PART I

ITEM 1. BUSINESS.

AEI Income & Growth Fund XXI Limited Partnership (the "Partnership" or the "Registrant") is a limited partnership which was organized pursuant to the laws of the State of Minnesota on August 22, 1994. The registrant is comprised of AEI Fund Management XXI, Inc. (“AFM”) as Managing General Partner, the Estate of Robert P. Johnson as the Individual General Partner, and purchasers of partnership units as Limited Partners. The Partnership offered for sale up to $24,000,000 of limited partnership interests (the "Units") (24,000 Units at $1,000 per Unit) pursuant to a registration statement effective February 1, 1995. The Partnership commenced operations on April 14, 1995 when minimum subscriptions of 1,500 Limited Partnership Units ($1,500,000) were accepted. On January 31, 1997, the Partnership offering terminated when the maximum subscription limit of 24,000 Limited Partnership Units ($24,000,000) was reached.

The Partnership was organized to acquire existing and newly constructed commercial properties located in the United States, to lease such properties to tenants under net leases, to hold such properties and to eventually sell such properties. From subscription proceeds, the Partnership purchased ten properties including partial interests in seven properties, at a total cost of $19,686,525. The balance of the subscription proceeds was applied to organization and syndication costs, working capital reserves and distributions, which represented a return of capital. The properties are commercial, single tenant buildings leased under net leases.

The Partnership's properties were purchased without any indebtedness. The Partnership will not finance properties in the future to obtain proceeds for new property acquisitions. If it is required to do so, the Partnership may incur short-term indebtedness, which may be secured by a portion of the Partnership's properties, to finance day-to-day cash flow requirements (including cash flow necessary to repurchase Units). The amount of borrowings that may be secured by the properties is limited in the aggregate to 10% of the purchase price of all properties. The Partnership will not incur borrowings to pay distributions and will not incur borrowings while there is cash available for distributions.

The Partnership will hold its properties until the General Partners determine that the sale or other disposition of the properties is advantageous in view of the Partnership's investment objectives. In deciding whether to sell properties, the General Partners will consider factors such as potential appreciation, net cash flow and income tax considerations. The Partnership expects to sell some or all of its properties prior to its final liquidation and to reinvest the proceeds from such sales in additional properties. The Partnership reserves the right, at the discretion of the General Partners, to either distribute proceeds from the sale of properties to the Partners or to reinvest such proceeds in additional properties, provided that sufficient proceeds are distributed to the Limited Partners to pay federal and state income taxes related to any taxable gain recognized as a result of the sale.

2

ITEM 1. BUSINESS. (Continued)

In January 2021, the Managing General Partner mailed a Consent Statement (Proxy) seeking the consent of the Limited Partners to continue the Partnership for an additional 60 months or to initiate the final disposition, liquidation and distribution of all of the Partnership’s properties and assets. On March 3, 2021, the votes were counted and neither proposal received the required majority vote. As a result, the Managing General Partner will continue the operations of the Partnership for an additional 60 months at which time it will ask the Limited Partners to vote on the same two proposals.

Leases

Although there are variations in the specific terms of the leases, the following is a summary of the general terms of the Partnership's leases. The properties are leased to tenants under net leases, classified as operating leases. Under a net lease, the tenant is responsible for real estate taxes, insurance, maintenance, repairs and operating expenses for the property. For some leases, the Partnership is responsible for repairs to the structural components of the building, the roof, and the parking lot. At the time the properties were acquired, the remaining primary lease terms varied from 10 to 18 years. The leases provide the tenants with two to four five-year renewal options subject to the same terms and conditions as the primary term. The leases provide for base annual rental payments, payable in monthly installments, and contain rent clauses which entitle the Partnership to receive additional rent in future years based on stated rent increases.

Property Activity During the Last Three Years

As of December 31, 2018, the Partnership owned interests in seven properties with a total cost of $14,645,171. During the years ended December 31, 2019, 2020 and 2021, the Partnership sold three property interests and received net sale proceeds of $2,730,563, $1,465,286 and $2,477,214, which resulted in net gains of $804,853, $677,237 and $13,198, respectively. During 2021, the Partnership expended $1,805,735 to purchase one additional property interest as it reinvested cash generated from property sales. As of December 31, 2021, the Partnership owned interests in five properties with a total cost of $10,708,539.

Major Tenants

During 2021, three tenants each contributed more than ten percent of the Partnership's total rental income. The major tenants in aggregate contributed 87% of total rental income in 2021. It is anticipated that, based on minimum rental payments required under the leases, each major tenant will continue to contribute more than ten percent of rental income in 2022. Additionally, the tenant Advanced Auto will become a major tenant because the property was purchased in 2021. Any failure of these major tenants could materially affect the Partnership's net income and cash distributions.

ITEM 1. BUSINESS. (Continued)

Competition

The Partnership is a minor factor in the commercial real estate business. There are numerous entities engaged in the commercial real estate business which have greater financial resources than the Partnership. At the time the Partnership elects to dispose of its properties, the Partnership will be in competition with other persons and entities to find buyers for its properties.

Employees

The Partnership has no direct employees. Management services are performed for the Partnership by AEI Fund Management, Inc. (Management Company), an affiliate of AFM. For the past two fiscal years, despite the COVID-19 pandemic, the Management Company has not made any reductions to employee compensation plans or employee benefit plans. The Management Company has increased the number of employees from 36 on December 31, 2020 to 39 at December 31, 2021 to support AFM’s business operations.

The Management Company believes the people who work for the company are its most important resources and are critical to its continued success. The Management Company focuses significant attention toward attracting and retaining talented and experienced individuals to manage and support its operations. The Management Company’s people are expected to exhibit and promote honest, ethical and respectful conduct in the workplace. All of the Management Company’s employees must adhere to a code of conduct that is outlined in AEI’s employee handbook which sets standards for appropriate behavior which includes preventing, identifying, reporting and stopping any type of discrimination.

Compensation and Benefits

The Management Company believes its compensation package and benefits are competitive with others in its industry. In addition to base pay, all eligible employees participate in the Management Company bonus program. The Management Company also offers employees a broad range of benefits, including medical, dental and ancillary health benefits and paid parental leave.

Workplace Safety and Wellness

The safety and well-being of the Management Companies employees is its priority. During the COVID-19 pandemic, the Management Company implemented a COVID-19 Preparedness Plan which included safety protocols to assist in mitigating the risk of exposure to its employees and visitors. These protocols include complying with health and safety standards as required by federal, state and local government agencies, taking into consideration guidelines of the Centers for Disease Control and Prevention and other public health authorities. Many of the Management Company’s operational functions during this time have required modification, including most of its employees working remotely. The Management Company’s experienced teams of people adapted to the changes in the work environment and have managed business successfully during this challenging time.

Investment Objectives

The Partnership's investment objectives are to acquire existing or newly-developed commercial properties throughout the United States that offer the potential for (i) regular cash distributions of lease income; (ii) growth in lease income through rent escalation provisions; (iii) preservation of capital through all-cash transactions; (iv) capital growth through appreciation in the value of properties; and (v) stable property performance through long-term lease contracts. The Partnership does not have a policy, and there is no limitation, as to the amount or percentage of assets that may be invested in any one property. However, to the extent possible, the General Partners attempt to diversify the properties by tenant and geographic location.

Description of Properties

The Partnership's properties are commercial, single tenant buildings. The properties were acquired on a debt-free basis and are leased to tenants under net leases, classified as operating leases. The Partnership holds an undivided fee simple interest in the properties.

The Partnership's properties are subject to the general competitive conditions incident to the ownership of single tenant investment real estate. Since each property is leased under a longterm lease, there is little competition until the Partnership decides to sell the property. At this time, the Partnership will be competing with other real estate owners, on both a national and local level, in attempting to find buyers for the properties. In the event of a tenant default, the Partnership would be competing with other real estate owners, who have property vacancies, to attract a new tenant to lease the property. The Partnership's tenants operate in industries that are competitive and can be affected by factors such as changes in regional or local economies, seasonality and changes in consumer preference.

ITEM 2. PROPERTIES. (Continued)

The following table is a summary of the properties that the Partnership acquired and owned as of December 31, 2021.

(1)  Does not include acquisition costs that were expensed.

The properties listed above with a partial ownership percentage are owned with the following affiliated entities:  Jared Jewelry store in Hanover, Maryland (AEI Net Lease Income & Growth Fund XX Limited Partnership); Jared Jewelry store in Auburn Hills, Michigan (AEI Income & Growth Fund 25 LLC); and Best Buy store (AEI Income & Growth Fund 26 LLC).

The Partnership accounts for properties owned as tenants-in-common with affiliated entities and/or unrelated third parties using the proportionate consolidation method. Each tenant-in-common owns a separate, undivided interest in the properties. Any tenant-in-common that holds more than a 50% interest does not control decisions over the other tenant-in-common interests. The financial statements reflect only this Partnership's percentage share of the properties' land, building, liabilities, revenues and expenses.

At the time the properties were acquired, the remaining primary lease terms varied from 10 to 18 years. The leases provide the tenants with two to four five-year renewal options subject to the same terms and conditions as the primary term. The leases for the Best Buy store, Jared Jewelry store in Auburn Hills, and Jared Jewelry store in Hanover were extended to end on January 19, 2023, December 31, 2024, and January 31, 2029, respectively.

Pursuant to the lease agreements, the tenants are required to provide proof of adequate insurance coverage on the properties they occupy. The General Partners believe the properties are adequately covered by insurance and consider the properties to be well-maintained and sufficient for the Partnership's operations.

ITEM 2. PROPERTIES. (Continued)

For tax purposes, the Partnership's properties are depreciated under the Modified Accelerated Cost Recovery System (MACRS). The largest depreciable component of a property is the building which is depreciated using the straight-line method over 39 years. The remaining depreciable component of a property is land improvements which are depreciated using an accelerated method over 15 years. Since the Partnership has tax-exempt Partners, the Partnership is subject to the rules of Section 168(h)(6) of the Internal Revenue Code which requires a percentage of the properties' depreciable components to be depreciated over longer lives using the straight-line method. In general, the federal tax basis of the properties for tax depreciation purposes equals the book depreciable cost of the properties plus the amortizable cost of the related intangible lease assets, except for properties purchased during 2009 through 2017. For those properties, acquisition expenses that were expensed for book purposes were capitalized and added to the basis of the property for tax depreciation purposes.

At December 31, 2021, all properties listed above were 100% occupied.

Other Information

Effective April 11, 2016, the Financial Industry Regulatory Authority (“FINRA”) implemented Rule 2310, a revised rule that requires securities broker-dealers to report on customer account statements the value of investment units of non-traded securities, such as REITs, LLCs and Limited Partnerships, provided that the per unit value is derived using methodology set forth by the rule.

At December 31, 2021, the estimated value of the Partnership's Units was $808 per Unit. The Managing General Partner is the party responsible for the estimated value per Unit. The estimated value was derived using methodology that conforms to standard industry practice and based upon material assistance and/or confirmation by third-party valuation expert(s), in accordance with the appraised value method set forth in FINRA Rule 2340(c)(1)(B).

ITEM 5. MARKET FOR REGISTRANT’S COMMON EQUITY, RELATED STOCK-

                 HOLDER MATTERS AND ISSUER PURCHASES OF EQUITY SECURITIES.

In determining the estimated value of each property, the Managing General Partner relied on some or all of the following external information sources, as well as its own experience in the commercial, net leased property industry and knowledge of each property:

●

Opinions of value from real estate brokerage firms

●

Appraisal reports from independent commercial property appraisers

●

Industry market reports from real estate brokerage and appraisal firms

●

Market values from comparable properties listed for sale or recently sold

●

Interviews with real estate brokers and tenants

●

Tenant financial reports and other credit information, where available

The per Unit value was the aggregate estimated value of the Partnership's assets less the Partnership's liabilities, and less the value attributable to the interest of the General Partners, divided by the number of Units outstanding. The Partnership's cash, receivables and liabilities were valued at face value as of September 30, 2021. Each of the Partnership's properties were valued by dividing their annual rental income as of December 1, 2021 by a capitalization rate the Managing General Partner believed, based upon the aforementioned valuation process, to be representative of the retail market for the sale of each property. The resulting value for each property was reviewed to determine that it also reflected circumstances that may have been unique to each specific property. For recently acquired properties, an appraisal report received at or near the time of acquisition from an independent commercial property appraiser was used to determine the value of the property. The appraisal report is used to value the property for approximately one year after the date of acquisition. The valuations were estimates only, and were based on a number of assumptions which may not be accurate or complete. In addition, property values are subject to change and could decline after the date of the valuations. Accordingly, this estimated value should not be viewed as the amount at which a Limited Partner may be able to sell his units, or the fair market value of the Partnership properties, nor does it represent the amount of net proceeds Limited Partners would receive if the Partnership properties were sold and the proceeds distributed in a liquidation of the Partnership.

The following table provides a breakdown of each major asset type, liabilities and the number of Units that were used to calculate the estimated value per Unit, using the methodology described above, as of December 31, 2021 and 2020:

		December 31, 2021		December 31, 2020
Properties	$	11,225,000	$	10,197,000
Cash		3,269,000		4,567,000

ITEM 6. (Reserved)

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL

                 CONDITION AND RESULTS OF OPERATIONS.

This section contains "forward-looking statements" which represent management's expectations or beliefs concerning future events, including statements regarding anticipated application of cash, expected returns from rental income, growth in revenue, the sufficiency of cash to meet operating expenses, rates of distribution, and other matters. These, and other forward-looking statements, should be evaluated in the context of a number of factors that may affect the Partnership's financial condition and results of operations, including the following:

—

Market and economic conditions which affect the value of the properties the Partnership owns and the cash from rental income such properties generate;

—

the federal income tax consequences of rental income, deductions, gain on sales and other items and the effects of these consequences for the Partners;

—

resolution by the General Partners of conflicts with which they may be confronted;

—

the success of the General Partners of locating properties with favorable risk return characteristics;

—

the effect of tenant defaults; and

—

the condition of the industries in which the tenants of properties owned by the Partnership operate.

Application of Critical Accounting Policies

The Partnership’s financial statements have been prepared in accordance with US GAAP. Preparing the financial statements requires management to use judgment in the application of these accounting policies, including making estimates and assumptions. These judgments will affect the reported amounts of the Partnership’s assets and liabilities and the disclosure of contingent assets and liabilities as of the dates of the financial statements and will affect the reported amounts of revenue and expenses during the reporting periods. It is possible that the carrying amount of the Partnership’s assets and liabilities, or the results of reported operations, will be affected if management’s estimates or assumptions prove inaccurate.

Management of the Partnership evaluates the following accounting estimates on an ongoing basis, and has discussed the development and selection of these estimates and the management discussion and analysis disclosures regarding them with the managing partner of the Partnership.

10

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS. (Continued)

Allocation of Purchase Price of Acquired Properties

Upon acquisition of real properties, the Partnership records them in the financial statements at cost. The purchase price is allocated to tangible assets, consisting of land and building, and to identified intangible assets and liabilities, which may include the value of above market and below market leases and the value of in-place leases. The allocation of the purchase price is based upon the relative fair value of each component of the property. Although independent appraisals may be used to assist in the determination of fair value, in many cases these values will be based upon management’s assessment of each property, the selling prices of comparable properties and the discounted value of cash flows from the asset.

The fair values of above market and below market in-place leases will be recorded based on the present value (using an interest rate which reflects the risks associated with the leases acquired) of the difference between (i) the contractual amounts to be paid pursuant to the in-place leases and (ii) an estimate of fair market lease rates for the corresponding in-place leases measured over a period equal to the non-cancelable term of the lease including any bargain renewal periods. The above market and below market lease values will be capitalized as intangible lease assets or liabilities. Above market lease values will be amortized as an adjustment of rental income over the remaining term of the respective leases. Below market lease values will be amortized as an adjustment of rental income over the remaining term of the respective leases, including any bargain renewal periods. If a lease were to be terminated prior to its stated expiration, all unamortized amounts of above market and below market in-place lease values relating to that lease would be recorded as an adjustment to rental income.

The fair values of in-place leases will include estimated direct costs associated with obtaining a new tenant, and opportunity costs associated with lost rentals which are avoided by acquiring an in-place lease. Direct costs associated with obtaining a new tenant may include commissions, tenant improvements, and other direct costs and are estimated, in part, by management’s consideration of current market costs to execute a similar lease. These direct costs will be included in intangible lease assets on the balance sheet and will be amortized to expense over the remaining term of the respective leases. The value of opportunity costs will be calculated using the contractual amounts to be paid pursuant to the in-place leases over a market absorption period for a similar lease. These intangibles will be included in intangible lease assets on the balance sheet and will be amortized to expense over the remaining term of the respective leases. If a lease were to be terminated prior to its stated expiration, all unamortized amounts of in-place lease assets relating to that lease would be expensed.

The determination of the relative fair values of the assets and liabilities acquired will require the use of significant assumptions with regard to the current market rental rates, rental growth rates, discount and capitalization rates, interest rates and other variables. If management’s estimates or assumptions prove inaccurate, the result would be an inaccurate allocation of purchase price, which could impact the amount of reported net income.

11

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS. (Continued)

Carrying Value of Properties

Properties are carried at original cost, less accumulated depreciation and amortization. The Partnership tests long-lived assets for recoverability when events or changes in circumstances indicate that the carrying value may not be recoverable. For properties the Partnership will hold and operate, management determines whether impairment has occurred by comparing the property’s probability-weighted future undiscounted cash flows to its current carrying value. For properties held for sale, management determines whether impairment has occurred by comparing the property’s estimated fair value less cost to sell to its current carrying value. If the carrying value is greater than the net realizable value, an impairment loss is recorded to reduce the carrying value of the property to its net realizable value. Changes in these assumptions or analysis may cause material changes in the carrying value of the properties.

Allocation of Expenses

AEI Fund Management, Inc. allocates expenses to each of the funds they manage primarily on the basis of the number of hours devoted by their employees to each fund’s affairs. They also allocate expenses at the end of each month that are not directly related to a fund’s operations based upon the number of investors in the fund and the fund’s capitalization relative to other funds they manage. The Partnership reimburses these expenses subject to detailed limitations contained in the Partnership Agreement.

Factors Which May Influence Results of Operations

The Partnership is not aware of any material trends or uncertainties, other than national economic conditions affecting real estate generally, that may reasonably be expected to have a material impact, favorable or unfavorable, on revenues and investment property value. However, due to the outbreak of the coronavirus (COVID-19) in the U.S. and globally, our tenants and operating partners may be impacted. See Note 8 on COVID-19 effect on our operations. The impact of COVID-19 on our future results could still be significant and will largely depend on continuing developments, which are highly uncertain and cannot be predicted, including new information which may emerge concerning the severity of COVID-19, the success of actions taken to contain or treat COVID-19, and reactions by consumers, companies, governmental entities and capital markets.

Results of Operations

For the years ended December 31, 2021 and 2020, the Partnership recognized rental income of $838,417 and $830,552, respectively. In 2021, rental income increased due to one property acquisition and rent commencement of the Burlington retail store discussed below. These increases were partially offset by the sale of one property in 2020. Based on the scheduled rent for the properties owned as of February 28, 2022, the Partnership expects to recognize rental income of approximately $628,000 in 2022.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS. (Continued)

For the years ended December 31, 2021 and 2020, the Partnership incurred Partnership administration expenses from affiliated parties of $157,584 and $138,479, respectively. These administration expenses include costs associated with the management of the properties, processing distributions, reporting requirements and communicating with the Limited Partners. During the same periods, the Partnership incurred Partnership administration and property management expenses from unrelated parties of $87,413 and $87,103, respectively. These expenses represent direct payments to third parties for legal and filing fees, direct administrative costs, outside audit costs, taxes, insurance and other property costs.

The Partnership owned a 30% interest in the Gander Mountain store in Champaign, Illinois. The remaining interests in the property were owned by affiliates of the Partnership. On March 10, 2017, Gander Mountain Company filed for Chapter 11 reorganization and announced it was closing the store, following a liquidation sale of its onsite assets. In June 2017, the tenant filed a motion with the bankruptcy court to reject the lease for this store effective June 30, 2017. At this time, the tenant returned possession of the property to the owners and the Partnership became responsible for its 30% share of real estate taxes and other costs associated with maintaining the property. The tenant paid rent through June 2017.

On August 11, 2020, the Partnership entered into a lease agreement with a primary term of 10 years with Burlington Coat Factory of Texas, Inc. (“Burlington”) as a replacement tenant for 62% of the square footage of the property. The tenant’s obligations under the lease are guaranteed by Burlington Coat Factory Warehouse Corporation. The tenant will operate a Burlington retail store in the space. The Partnership’s 30% share of annual rent is $102,980 and commenced on May 7, 2021. The Partnership was responsible for paying its 30% share of the buildout of the space, which was $612,992. As part of the agreement, the Partnership paid a tenant improvement allowance of $66,201 that was capitalized. The Partnership paid its 30% share of lease commissions due to real estate brokers totaling $63,443 that were owed as part of the lease transaction. This amount was capitalized and is being amortized over the term of the lease.

On February 5, 2021, the Partnership entered into a lease agreement with a primary term of 10 years with Five Below, Inc. as a replacement tenant for 38% of the square footage of the property. The tenant will operate a Five Below retail store in the space. The Partnerships 30% share of the annual rent is $62,093 and commenced on August 27, 2021. The Partnership is responsible for its 30% share of the buildout of the space, which was $250,988. As part of the agreement, the Partnership paid a tenant improvement allowance of $21,995 that was capitalized. The Partnership paid its 30% share of lease commissions due to real estate brokers totaling $40,804 that were due as part of the lease transaction. This amount was capitalized and will be amortized over the term of the lease.

In March 2019, the Partnership entered into an agreement with the tenant of the Jared Jewelry store in Auburn Hills, Michigan to extend the lease term five years to end on December 31, 2024. As part of the agreement, the annual rent decreased from $124,049 to $105,560 effective January 1, 2020.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS. (Continued)

In July 2021, the Partnership entered into an agreement with the tenant of the Jared Jewelry store in Hanover, Maryland to extend the lease term seven years to end on January 31, 2029. As part of the agreement, the annual rent will decrease from $224,340 to $167,500 effective February 1, 2022.

For the years ended December 31, 2021 and 2020, the Partnership recognized interest income of $3,608 and $8,181, respectively.

Management believes inflation has not significantly affected income from operations. Leases may contain rent increases, based on the increase in the Consumer Price Index over a specified period, which will result in an increase in rental income over the term of the leases. Inflation also may cause the real estate to appreciate in value. However, inflation and changing prices may have an adverse impact on the operating margins of the properties' tenants, which could impair their ability to pay rent and subsequently reduce the Net Cash Flow available for distributions.

Liquidity and Capital Resources

During the year ended December 31, 2021, the Partnership's cash balance decreased $1,082,540 primarily as a result of distributions paid to the Partners and cash used to repurchase units in excess of cash generated from operating activities and cash used for property and lease acquisition costs, which was partially offset by cash generated from the sale of a property. During the year ended December 31, 2020, the Partnership's cash balances increased $1,110,717 as a result of cash generated from the sale of property, which was partially offset by distributions paid to the Partners in excess of cash generated from operating activities and cash used for property and lease acquisition costs.

Net cash provided by operating activities decreased from $593,239 in 2020 to $570,493 in 2021 as a result of net timing differences in the collection of payments from the tenants and the payment of expenses in addition to a decrease in interest income, which was partially offset by an increase in total rental income in 2021.

The major components of the Partnership's cash flow from investing activities are investments in real estate and proceeds from the sale of real estate. During the years ended December 31, 2021 and 2020, the partnership expended $740,125 and $316,297, respectively, of property and lease acquisition costs related to its property in Champaign, Illinois. During the same periods, the Partnership generated cash flow from the sale of real estate of $2,477,214 and $1,465,286, respectively. During the same periods, the Partnership expended $2,545,860 and $316,297, respectively, to invest in real properties.

In October 2020, the Partnership entered into an agreement to sell its 55% interest in the Fresenius Medical Center in Shreveport, Louisiana to an unrelated third party. On December 18, 2020, the sale closed with the Partnership receiving net proceeds of $1,465,286, which resulted in a net gain of $677,237. At the time of sale, the cost and related accumulated depreciation was $1,407,367 and $619,318, respectively.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS. (Continued)

On May 14, 2021, the Partnership purchased an Advance Auto Parts store in Chelsea, Alabama for $1,802,200. The Partnership allocated $158,736 of the purchase price to Acquired Intangible Lease Assets, representing in-place lease intangibles. The property is leased to Advance Stores Company, Incorporated under a lease agreement with a remaining primary term of 10.4 years (as of the date of purchase) and annual rent of $110,000.

In August 2021, the Partnership entered into an agreement to sell its 30% interest in the Burlington Coat Factory and Five Below in Champaign, Illinois to an unrelated third party. On September 28, 2021, the sale closed with the Partnership receiving net proceeds of $2,477,214, which resulted in a net gain of $13,198. At the time of the sale, the cost and related accumulated depreciation was $3,178,923 and $714,907, respectively.

In December 2021, the Partnership entered into an agreement to sell its 50% interest in the Jared Jewelry store in Hanover, Maryland to an unrelated third party. On February 14, 2022, the sale closed with the Partnership receiving net proceeds of approximately $2,464,000, which resulted in a net gain of approximately $1,282,000. At the time of sale, the cost and related accumulated depreciation was $1,989,135 and $806,579, respectively.

On March 22, 2022, the Partnership purchase a 40% interest of the Memorial Hospital property in Diamondhead Mississippi for $1,580,000.  The partnership estimates it will allocated $196,000 of the purchase price to Acquired Lease Assets, representing in-place intangibles.  The property is leased to Memorial Hospital at Gulfport, Incorporated under a lease agreement with a remaining primary term of 5.3 years (as of date of purchase) and annual rent of $100,320 scheduled to increase annually at 2%.

The Partnership's primary use of cash flow, other than investment in real estate, is distribution payments to Partners and cash used to repurchase Units. The Partnership declares its regular quarterly distributions before the end of each quarter and pays the distribution in the first week after the end of each quarter. The Partnership attempts to maintain a stable distribution rate from quarter to quarter. The Partnership may repurchase tendered Units on April 1st and October 1st of each year subject to limitations.

For the years ended December 31, 2021 and 2020, the Partnership declared distributions of $613,731 and $567,269, respectively, which were distributed 99% to the Limited Partners and 1% to the General Partners. The Limited Partners received distributions of $607,594 and $561,596 and the General Partners received distributions of $6,137 and $5,673 for the years, respectively. The Partnership temporarily reduced distribution rates for the three month periods ended June 30 and September 30, 2020 due to rent deferral agreements entered with tenants and concerns regarding the ongoing COVID-19 situation.

15

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS. (Continued)

The Partnership may repurchase Units from Limited Partners who have tendered their Units to the Partnership. Such Units may be acquired at a discount. The Partnership will not be obligated to purchase in any year any number of Units that, when aggregated with all other transfers of Units that have occurred since the beginning of the same calendar year (excluding Permitted Transfers as defined in the Partnership Agreement), would exceed 5% of the total number of Units outstanding on January 1 of such year. In no event shall the Partnership be obligated to purchase Units if, in the sole discretion of the Managing General Partner, such purchase would impair the capital or operation of the Partnership.

On April 1, 2021, the Partnership repurchased a total of 843.97 Units for $610,604 from 36 Limited Partners in accordance with the Partnership Agreement. The Partnership acquired these Units using net sales proceeds. On October 1, 2021, the Partnership repurchased a total of 518.17 Units for $389,248 from 39 Partners. The Partnership acquired these Units using net sales proceeds. The repurchases increase the remaining Limited Partners' ownership interest in the Partnership. As a result of these repurchases and pursuant to the Partnership Agreement, the General Partners received distributions of $10,100 in 2021. During 2020, the Partnership did not repurchase any Units from Limited Partners.

The continuing rent payments from the properties, together with cash generated from property sales, should be adequate to fund continuing distributions and meet other Partnership obligations on both a short-term and long-term basis.

Off-Balance Sheet Arrangements

As of December 31, 2021, the Partnership had no material off-balance sheet arrangements that had or are reasonably likely to have current or future effects on its financial condition, results of operations, liquidity or capital resources.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Partners:

AEI Income & Growth Fund XXI Limited Partnership

St. Paul, Minnesota

Opinion on the Financial Statements

We have audited the accompanying balance sheets of AEI Income & Growth Fund XXI Limited Partnership (a Minnesota limited partnership) (the "Partnership”) as of December 31, 2021 and 2020, and the related statements of income, changes in partners’ capital, and cash flows for each of the years in the two-year period ended December 31, 2021, and the related notes (collectively referred to as the financial statements). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Partnership as of December 31, 2021 and 2020, and the results of its operations and its cash flows for each of the years in the two-year period ended December 31, 2021, in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

These financial statements are the responsibility of the Partnership’s management. Our responsibility is to express an opinion on the Partnership’s financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Partnership in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Partnership is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over financial reporting, but not for the purpose of expressing an opinion on the effectiveness of the Partnership’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matters

Critical audit matters are matters arising from the current period audit of the financial statements that were communicated or required to be communicated to the audit committee and that (1) relate to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. We determined that there were no critical audit matters.

AEI INCOME & GROWTH FUND XXI LIMITED PARTNERSHIP

NOTES TO FINANCIAL STATEMENTS

DECEMBER 31, 2021 AND 2020

(1)  Organization –

AEI Income & Growth Fund XXI Limited Partnership (“Partnership”) was formed to acquire and lease commercial properties to operating tenants. The Partnership's operations are managed by AEI Fund Management XXI, Inc. (“AFM”), the Managing General Partner. The Estate of Robert P. Johnson serves as the Individual General Partner. AFM is a wholly owned subsidiary of AEI Capital Corporation of which the Robert P. Johnson Trust and Patricia Johnson, the wife of the deceased, own a majority interest. AEI Fund Management, Inc. (“AEI”), an affiliate of AFM, performs the administrative and operating functions for the Partnership.

The terms of the Partnership offering called for a subscription price of $1,000 per Limited Partnership Unit, payable on acceptance of the offer. The Partnership commenced operations on April 14, 1995 when minimum subscriptions of 1,500 Limited Partnership Units ($1,500,000) were accepted. On January 31, 1997, the offering terminated when the maximum subscription limit of 24,000 Limited Partnership Units was reached. Under the terms of the Limited Partnership Agreement, the Limited Partners and General Partners contributed funds of $24,000,000 and $1,000, respectively.

During operations, any Net Cash Flow, as defined, which the General Partners determine to distribute will be distributed 90% to the Limited Partners and 10% to the General Partners; provided, however, that such distributions to the General Partners will be subordinated to the Limited Partners first receiving an annual, noncumulative distribution of Net Cash Flow equal to 10% of their Adjusted Capital Contribution, as defined, and, provided further, that in no event will the General Partners receive less than 1% of such Net Cash Flow per annum. Distributions to Limited Partners will be made pro rata by Units.

Any Net Proceeds of Sale, as defined, from the sale or financing of properties which the General Partners determine to distribute will, after provisions for debts and reserves, be paid in the following manner: (i) first, 99% to the Limited Partners and 1% to the General Partners until the Limited Partners receive an amount equal to: (a) their Adjusted Capital Contribution plus (b) an amount equal to 10% of their Adjusted Capital Contribution per annum, cumulative but not compounded, to the extent not previously distributed from Net Cash Flow;  (ii) any remaining balance will be distributed 90% to the Limited Partners and 10% to the General Partners. Distributions to the Limited Partners will be made pro rata by Units.

For tax purposes, profits from operations, other than profits attributable to the sale, exchange, financing, refinancing or other disposition of property, will be allocated first in the same ratio in which, and to the extent, Net Cash Flow is distributed to the Partners for such year. Any additional profits will be allocated in the same ratio as the last dollar of Net Cash Flow is distributed. Net losses from operations will be allocated 99% to the Limited Partners and 1% to the General Partners.

23

AEI INCOME & GROWTH FUND XXI LIMITED PARTNERSHIP

NOTES TO FINANCIAL STATEMENTS

DECEMBER 31, 2021 AND 2020

(1)  Organization – (Continued)

For tax purposes, profits arising from the sale, financing, or other disposition of property will be allocated in accordance with the Partnership Agreement as follows: (i) first, to those partners with deficit balances in their capital accounts in an amount equal to the sum of such deficit balances; (ii) second, 99% to the Limited Partners and 1% to the General Partners until the aggregate balance in the Limited Partners' capital accounts equals the sum of the Limited Partners' Adjusted Capital Contributions plus an amount equal to 10% of their Adjusted Capital Contributions per annum, cumulative but not compounded, to the extent not previously allocated; (iii) third, the balance of any remaining gain will then be allocated 90% to the Limited Partners and 10% to the General Partners. Losses will be allocated 98% to the Limited Partners and 2% to the General Partners.

The General Partners are not required to currently fund a deficit capital balance. Upon liquidation of the Partnership or withdrawal by a General Partner, the General Partners will contribute to the Partnership an amount equal to the lesser of the deficit balances in their capital accounts or 1% of total Limited Partners' and General Partners' capital contributions.

In January 2021, the Managing General Partner mailed a Consent Statement (Proxy) seeking the consent of the Limited Partners to continue the Partnership for an additional 60 months or to initiate the final disposition, liquidation and distribution of all of the Partnership’s properties and assets. On March 3, 2021, the votes were counted and neither proposal received the required majority vote. As a result, the Managing General Partner will continue the operations of the Partnership for an additional 60 months at which time it will ask the Limited Partners to vote on the same two proposals.

(2)  Summary of Significant Accounting Policies –

Financial Statement Presentation

The accounts of the Partnership are maintained on the accrual basis of accounting for both federal income tax purposes and financial reporting purposes.

Accounting Estimates

Management uses estimates and assumptions in preparing these financial statements in accordance with United States Generally Accepted Accounting Principles (US GAAP). Those estimates and assumptions may affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities, and the reported revenues and expenses. Actual results could differ from those estimates, and the difference could be material. Significant items, subject to such estimates and assumptions, include the carrying value of real estate held for investment, real estate held for sale and the allocation of purchase price of real estate assets and intangible assets.

24

AEI INCOME & GROWTH FUND XXI LIMITED PARTNERSHIP

NOTES TO FINANCIAL STATEMENTS

DECEMBER 31, 2021 AND 2020

(2)  Summary of Significant Accounting Policies – (Continued)

The Partnership regularly assesses whether market events and conditions indicate that it is reasonably possible to recover the carrying amounts of its investments in real estate from future operations and sales. A change in those market events and conditions could have a material effect on the carrying amount of its real estate.

Cash Concentrations of Credit Risk

The Partnership's cash is deposited in one financial institution and at times during the year it may exceed FDIC insurance limits.

Rent Receivables

Credit terms are extended to tenants in the normal course of business. The Partnership performs ongoing credit evaluations of its customers’ financial condition and, generally, requires no collateral.

Rent receivables are recorded at their estimated net realizable value. The Partnership follows a policy of providing an allowance for doubtful accounts; however, based on historical experience, and its evaluation of the current status of receivables, the Partnership is of the belief that such accounts, if any, will be collectible in all material respects and thus an allowance is not necessary. Accounts are considered past due if payment is not made on a timely basis in accordance with the Partnership’s credit terms. Receivables considered uncollectible are written off.

Income Taxes

The income or loss of the Partnership for federal income tax reporting purposes is includable in the income tax returns of the partners. In general, no recognition has been given to income taxes in the accompanying financial statements.

The tax return and the amount of distributable Partnership income or loss are subject to examination by federal and state taxing authorities. If such an examination results in changes to distributable Partnership income or loss, the taxable income of the partners would be adjusted accordingly. Primarily due to its tax status as a partnership, the Partnership has no significant tax uncertainties that require recognition or disclosure. The Partnership is no longer subject to U.S. federal income tax examinations for tax years before 2018, and with few exceptions, is no longer subject to state tax examinations for tax years before 2018.

AEI INCOME & GROWTH FUND XXI LIMITED PARTNERSHIP

NOTES TO FINANCIAL STATEMENTS

DECEMBER 31, 2021 AND 2020

(2)  Summary of Significant Accounting Policies – (Continued)

Revenue Recognition

The Partnership's real estate is leased under net leases, classified as operating leases. The leases provide for base annual rental payments payable in monthly installments. The Partnership recognizes rental income according to the terms of the individual leases. For deferred rents due to COVID-19, the Partnership recognizes the deferred rent related to the month it applies and records a rental receivable. For leases that contain stated rental increases, the increases are recognized in the year in which they are effective. Contingent rental payments are recognized when the contingencies on which the payments are based are satisfied and the rental payments become due under the terms of the leases.

Real Estate Investments

Upon acquisition of real properties, the Partnership records them in the financial statements at cost. The purchase price is allocated to tangible assets, consisting of land and building, and to identified intangible assets and liabilities, which may include the value of above market and below market leases and the value of in-place leases. The allocation of the purchase price is based upon the relative fair value of each component of the property. Although independent appraisals may be used to assist in the determination of fair value, in many cases these values will be based upon management’s assessment of each property, the selling prices of comparable properties and the discounted value of cash flows from the asset.

The fair values of above market and below market in-place leases will be recorded based on the present value (using an interest rate which reflects the risks associated with the leases acquired) of the difference between (i) the contractual amounts to be paid pursuant to the in-place leases and (ii) an estimate of fair market lease rates for the corresponding in-place leases measured over a period equal to the non-cancelable term of the lease including any bargain renewal periods. The above market and below market lease values will be capitalized as intangible lease assets or liabilities. Above market lease values will be amortized as an adjustment of rental income over the remaining term of the respective leases. Below market lease values will be amortized as an adjustment of rental income over the remaining term of the respective leases, including any bargain renewal periods. If a lease were to be terminated prior to its stated expiration, all unamortized amounts of above market and below market in-place lease values relating to that lease would be recorded as an adjustment to rental income.

26

AEI INCOME & GROWTH FUND XXI LIMITED PARTNERSHIP

NOTES TO FINANCIAL STATEMENTS

DECEMBER 31, 2021 AND 2020

(2)  Summary of Significant Accounting Policies – (Continued)

The fair values of in-place leases will include estimated direct costs associated with obtaining a new tenant, and opportunity costs associated with lost rentals which are avoided by acquiring an in-place lease. Direct costs associated with obtaining a new tenant may include commissions, tenant improvements, and other direct costs and are estimated, in part, by management’s consideration of current market costs to execute a similar lease. These direct costs will be included in intangible lease assets on the balance sheet and will be amortized to expense over the remaining term of the respective leases. The value of opportunity costs will be calculated using the contractual amounts to be paid pursuant to the in-place leases over a market absorption period for a similar lease. These intangibles will be included in intangible lease assets on the balance sheet and will be amortized to expense over the remaining term of the respective leases. If a lease were to be terminated prior to its stated expiration, all unamortized amounts of in-place lease assets relating to that lease would be expensed.

The Partnership tests real estate for recoverability when events or changes in circumstances indicate that the carrying value may not be recoverable. For properties the Partnership will hold and operate, it compares the carrying amount of the property to the estimated probability-weighted future undiscounted cash flows expected to result from the property and its eventual disposition. If the sum of the expected future cash flows is less than the carrying amount of the property, the Partnership recognizes an impairment loss equal to the amount by which the carrying amount of the property exceeds the fair value of the property. For properties held for sale, the Partnership determines whether impairment has occurred by comparing the property’s estimated fair value less cost to sell to its current carrying value. If the carrying value is greater than the net realizable value, an impairment loss is recorded to reduce the carrying value of the property to its net realizable value.

For financial reporting purposes, the buildings owned by the Partnership are depreciated using the straight-line method over an estimated useful life of 25 years. Intangible lease assets are amortized using the straight-line method for financial reporting purposes based on the remaining life of the lease.

The disposition of a property or classification of a property as Real Estate Held for Sale by the Partnership does not represent a strategic shift that will have a major effect on the Partnership’s operations and financial results. Therefore, the results from operating and selling the property are included in continuing operations.

The Partnership accounts for properties owned as tenants-in-common with affiliated entities and/or unrelated third parties using the proportionate consolidation method. Each tenant-in-common owns a separate, undivided interest in the properties. Any tenant-in-common that holds more than a 50% interest does not control decisions over the other tenant-in-common interests. The financial statements reflect only this Partnership's percentage share of the properties' land, building, intangible assets, liabilities, revenues and expenses.

(2)  Summary of Significant Accounting Policies – (Continued)

The Partnership's properties are subject to environmental laws and regulations adopted by various governmental entities in the jurisdiction in which the properties are located. These laws could require the Partnership to investigate and remediate the effects of the release or disposal of hazardous materials at these locations if found. For each property, an environmental assessment is completed prior to acquisition. In addition, the lease agreements typically strictly prohibit the production, handling, or storage of hazardous materials (except where incidental to the tenant’s business such as use of cleaning supplies) in violation of applicable law to restrict environmental and other damage. Environmental liabilities are recorded when it is determined the liability is probable and the costs can reasonably be estimated. There were no environmental issues noted or liabilities recorded at December 31, 2021 and 2020.

Fair Value Measurements

As of December 31, 2021 and 2020, the Partnership had no assets or liabilities measured at fair value on a recurring basis or nonrecurring basis.

Income Per Unit

Income per Limited Partnership Unit is calculated based on the weighted average number of Limited Partnership Units outstanding during each period presented. Diluted income per Limited Partnership Unit considers the effect of any potentially dilutive Unit equivalents, of which the Partnership had none for each of the years ended December 31, 2021 and 2020.

Reportable Segments

The Partnership invests in single tenant commercial properties throughout the United States that are net leased to tenants in various industries. Because these net leased properties have similar economic characteristics, the Partnership evaluates operating performance on an overall portfolio basis. Therefore, the Partnership’s properties are classified as one reportable segment.

Recently Adopted Accounting Pronouncements

In April 2020, the Financial Accounting Standards Board (FASB) issued a question-and-answer document (the “Lease Modification Q&A”) focused on the application of lease accounting guidance to lease concessions provided as a result of COVID-19. Under existing lease guidance, the Partnership would have to determine, on a lease by lease basis, if a lease concession was the result of a new arrangement reached with the tenant or if a lease concession was under the enforceable rights and obligations within the existing lease agreement. The Lease Modification Q&A clarifies that entities may elect to not evaluate whether lease-related relief that lessors provide to mitigate the economic effects of COVID-19 on lessees is a lease modification under current lease guidance. Instead, an entity that elects not to evaluate whether a concession directly related to COVID-19 is a modification can then elect whether to apply the modification guidance.

(2)  Summary of Significant Accounting Policies – (Continued)

During the year ended December 31, 2020, the Partnership provided lease concessions to certain tenants in response to the impact of COVID-19, in the form of rent deferrals. The Partnership has made an election to account for such lease concessions consistent with how those concessions would be accounted for under lease guidance if enforceable rights and obligations for those concessions had already existed in the leases. This election is available for concessions related to the effects of the COVID-19 pandemic that do not result in a substantial increase in the rights as lessor, including concessions that result in the total payments required by the modified lease being substantially the same as or less than total payments required by the original lease.

Substantially all of the Partnership’s concessions to date provide for a deferral of payments with no substantive changes to the consideration in the original lease. These deferrals affect the timing, but not the amount, of the lease payments. The Partnership is accounting for these deferrals as if no changes to the lease were made. Under this accounting, the Partnership increases its rent receivables as tenant payments accrue and continues to recognize rental income. During the year ended December 31, 2020, the Partnership has entered into lease modifications that deferred $51,584, which was recognized as rental income for those deferred months in 2020. The rent receivable related to these rental deferrals is $4,299 as of December 31, 2021.

Other accounting standards that have been issued or proposed by the FASB are currently not applicable to the Company or are not expected to have a significant impact on the Company’s financial position, results of operations and cash flows.

At the time the properties were acquired, the remaining primary lease terms varied from 10 to 18 years. The leases provide the tenants with two to four five-year renewal options subject to the same terms and conditions as the primary term. The leases for the Best Buy store, Jared Jewelry store in Auburn Hills, and Jared Jewelry store in Hanover were extended to end on January 19, 2023, December 31, 2024, and January 31, 2029, respectively.

(8)  COVID-19 Outbreak –

During the first quarter of 2020, there was a global outbreak of COVID-19 which continues to adversely impact global commercial activity and has contributed to significant volatility in financial markets. The global impact of the outbreak has been rapidly evolving, and as cases of the virus have continued to be identified in additional countries, many countries have reacted by instituting quarantines, placing restrictions on travel, and limiting hours of operations of non-essential offices and retail centers. Such actions are creating disruption in global supply chains, and adversely impacting a number of industries, such as retail, restaurants and transportation. The outbreak could have a continued adverse impact on economic and market conditions and trigger a period of global economic slowdown. The rapid development and fluidity of this situation precludes any prediction as to the ultimate adverse impact of COVID-19. Nevertheless, COVID19 presents material uncertainty and risk with respect to the Partnership’s performance and financial results, such as the potential negative impact to the tenants of its properties, the potential closure of certain of its properties, increased costs of operations, decrease in values of its properties, changes in law and/or regulation, and uncertainty regarding government and regulatory policy. Up to the date of this filing, the Partnership has entered into rent deferral agreements with two tenants of the six properties owned by the Partnership. In June 2020, the Partnership entered into an agreement with the tenant of the Jared Jewelry store in Auburn Hills, Michigan and Hanover, Maryland to defer base rent in April and May 2020. The tenants started paying the deferred amounts in twelve equal monthly installments beginning on February 1, 2021.

The Partnership has elected not to account for these deferrals of rent as a lease modification under COVID-19 guidance issued by the FASB. Deferred rent of $51,584 was recognized as rental income during the year ended December 31, 2020 and a corresponding rent receivable was recorded. The rent receivable related to these rental deferrals is $4,299 as of December 31, 2021. The Partnership continues to work closely with tenants to determine the best course of action to meet the tenants short-term rental needs during these unprecedented times.

Under the supervision and with the participation of management, including its President and Chief Financial Officer, the Managing General Partner of the Partnership evaluated the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rule 13a-15(e) under the Securities Exchange Act of 1934 (the “Exchange Act”)). Based upon that evaluation, the President and Chief Financial Officer of the Managing General Partner concluded that, as of the end of the period covered by this report, our disclosure controls and procedures were effective in ensuring that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in applicable rules and forms and that such information is accumulated and communicated to management, including the President and Chief Financial Officer of the Managing General Partner, in a manner that allows timely decisions regarding required disclosure.

(b)  Internal Control Over Financial Reporting.

(i) Management’s Report on Internal Control Over Financial Reporting. The Managing General Partner, through its management, is responsible for establishing and maintaining adequate internal control over our financial reporting, as defined in Rule 13a-15(f) under the Exchange Act, and for performing an assessment of the effectiveness of our internal control over financial reporting as of December 31, 2020. Internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with US GAAP. Our system of internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the Partnership; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with US GAAP, and that receipts and expenditures of the Partnership are being made only in accordance with authorizations of management of the Managing General Partner; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the Partnership's assets that could have a material effect on the financial statements.

Management of the Managing General Partner performed an assessment of the effectiveness of our internal control over financial reporting as of December 31, 2021 based upon criteria in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”). Based on our assessment, management of the Managing General Partner determined that our internal control over financial reporting was effective as of December 31, 2021 based on the criteria in Internal Control-Integrated Framework (2013) issued by the COSO.

All of the duties that might be assigned to an audit committee are assigned to Patricia Johnson, the wife of the deceased. Mrs. Johnson is not an audit committee financial expert, as defined.

Before the independent auditors are engaged, Mr. Johnson, as the sole director of AFM, approves all audit-related fees, and all permissible nonaudit fees, for services of our auditors.

Section 16(a) Beneficial Ownership Reporting Compliance

Under federal securities laws, the directors and officers of the General Partner of the Partnership, and any beneficial owner of more than 10% of a class of equity securities of the Partnership, are required to report their ownership of the Partnership's equity securities and any changes in such ownership to the Securities and Exchange Commission (the "Commission"). Specific due dates for these reports have been established by the Commission, and the Partnership is required to disclose in this Annual Report on 10-K any delinquent filing of such reports and any failure to file such reports during the fiscal year ended December 31, 2021. Based upon information provided by officers and directors of the General Partner, all officers, directors and 10% owners filed all reports on a timely basis in the 2021 fiscal year.

ITEM 11. EXECUTIVE COMPENSATION.

The General Partner and affiliates are reimbursed at cost for all services performed on behalf of the registrant and for all third party expenses paid on behalf of the registrant. The cost for services performed on behalf of the registrant is based on actual time spent performing such services plus an overhead burden. These services include organizing the registrant and arranging for the offer and sale of Units, reviewing properties for acquisition and rendering administrative, property management and property sales services. The amount and nature of such payments are detailed in Item 13 of this annual report on Form 10-K.

The persons set forth in the preceding table hold sole voting power and power of disposition with respect to all of the Units set forth opposite their names.

ITEM 13. CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS, AND

                   DIRECTOR INDEPENDENCE.

The registrant, AFM and its affiliates have common management and utilize the same facilities. As a result, certain administrative expenses are allocated among these related entities. All of such activities and any other transactions involving the affiliates of the General Partner of the registrant are governed by, and are conducted in conformity with, the limitations set forth in the Limited Partnership Agreement of the registrant. Reference is made to Note 3 of the Financial Statements, as presented, and is incorporated herein by reference, for details of related party transactions for the years ended December 31, 2021 and 2020.

Neither the registrant, nor the Managing General Partner of the registrant, has a board of directors consisting of any members who are “independent.”  In 2020 through date of his death, the sole director of the Managing General Partner, Robert P. Johnson, was also the Individual General Partner of the registrant, and was the Chief Executive Officer, and indirectly the principal owner, of the Managing General Partner. Patricia Johnson now serves as the sole director of the Managing General Partner.  Accordingly, there is no disinterested board, or other functioning body, that reviews related party transactions, or the transactions between the registrant and the General Partners, except as performed in connection with the audit of its financial statements.

41

ITEM 13. CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS, AND

                   DIRECTOR INDEPENDENCE. (Continued)

The cumulative reimbursements subject to this limitation are reimbursements for (i) organization and offering expenses, including commissions, (ii) acquisition expenses, (iii) services provided in the sales effort of properties, and (iv) expenses of controlling persons and overhead expenses directly attributable to the forgoing services or attributable to administrative services. As of December 31, 2021, these cumulative reimbursements to the General Partners and their affiliates did not exceed the limitation amount.

The following table sets forth the forms of compensation, distributions and cost reimbursements paid by the registrant to the General Partners or their Affiliates in connection with the operation of the Fund for the period from inception through December 31, 2021.

(1)  Organization –

AEI Income & Growth Fund XXI Limited Partnership (“Partnership”) was formed to acquire and lease commercial properties to operating tenants. The Partnership's operations are managed by AEI Fund Management XXI, Inc. (“AFM”), the Managing General Partner. The Estate of Robert P. Johnson serves as the Individual General Partner. AFM is a wholly owned subsidiary of AEI Capital Corporation of which the Robert P. Johnson Trust and Patricia Johnson, the wife of the deceased, own a majority interest. AEI Fund Management, Inc. (“AEI”), an affiliate of AFM, performs the administrative and operating functions for the Partnership.

The terms of the Partnership offering called for a subscription price of $1,000 per Limited Partnership Unit, payable on acceptance of the offer. The Partnership commenced operations on April 14, 1995 when minimum subscriptions of 1,500 Limited Partnership Units ($1,500,000) were accepted. On January 31, 1997, the offering terminated when the maximum subscription limit of 24,000 Limited Partnership Units was reached. Under the terms of the Limited Partnership Agreement, the Limited Partners and General Partners contributed funds of $24,000,000 and $1,000, respectively.

During operations, any Net Cash Flow, as defined, which the General Partners determine to distribute will be distributed 90% to the Limited Partners and 10% to the General Partners; provided, however, that such distributions to the General Partners will be subordinated to the Limited Partners first receiving an annual, noncumulative distribution of Net Cash Flow equal to 10% of their Adjusted Capital Contribution, as defined, and, provided further, that in no event will the General Partners receive less than 1% of such Net Cash Flow per annum. Distributions to Limited Partners will be made pro rata by Units.

Any Net Proceeds of Sale, as defined, from the sale or financing of properties which the General Partners determine to distribute will, after provisions for debts and reserves, be paid in the following manner: (i) first, 99% to the Limited Partners and 1% to the General Partners until the Limited Partners receive an amount equal to: (a) their Adjusted Capital Contribution plus (b) an amount equal to 10% of their Adjusted Capital Contribution per annum, cumulative but not compounded, to the extent not previously distributed from Net Cash Flow;  (ii) any remaining balance will be distributed 90% to the Limited Partners and 10% to the General Partners. Distributions to the Limited Partners will be made pro rata by Units.

For tax purposes, profits from operations, other than profits attributable to the sale, exchange, financing, refinancing or other disposition of property, will be allocated first in the same ratio in which, and to the extent, Net Cash Flow is distributed to the Partners for such year. Any additional profits will be allocated in the same ratio as the last dollar of Net Cash Flow is distributed. Net losses from operations will be allocated 99% to the Limited Partners and 1% to the General Partners.

For tax purposes, profits arising from the sale, financing, or other disposition of property will be allocated in accordance with the Partnership Agreement as follows: (i) first, to those partners with deficit balances in their capital accounts in an amount equal to the sum of such deficit balances; (ii) second, 99% to the Limited Partners and 1% to the General Partners until the aggregate balance in the Limited Partners' capital accounts equals the sum of the Limited Partners' Adjusted Capital Contributions plus an amount equal to 10% of their Adjusted Capital Contributions per annum, cumulative but not compounded, to the extent not previously allocated; (iii) third, the balance of any remaining gain will then be allocated 90% to the Limited Partners and 10% to the General Partners. Losses will be allocated 98% to the Limited Partners and 2% to the General Partners.

The General Partners are not required to currently fund a deficit capital balance. Upon liquidation of the Partnership or withdrawal by a General Partner, the General Partners will contribute to the Partnership an amount equal to the lesser of the deficit balances in their capital accounts or 1% of total Limited Partners' and General Partners' capital contributions.

In January 2021, the Managing General Partner mailed a Consent Statement (Proxy) seeking the consent of the Limited Partners to continue the Partnership for an additional 60 months or to initiate the final disposition, liquidation and distribution of all of the Partnership’s properties and assets. On March 3, 2021, the votes were counted and neither proposal received the required majority vote. As a result, the Managing General Partner will continue the operations of the Partnership for an additional 60 months at which time it will ask the Limited Partners to vote on the same two proposals.

Accounting Policies [Abstract]

Significant Accounting Policies [Text Block]

(2)  Summary of Significant Accounting Policies –

Financial Statement Presentation

The accounts of the Partnership are maintained on the accrual basis of accounting for both federal income tax purposes and financial reporting purposes.

Accounting Estimates

Management uses estimates and assumptions in preparing these financial statements in accordance with United States Generally Accepted Accounting Principles (US GAAP). Those estimates and assumptions may affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities, and the reported revenues and expenses. Actual results could differ from those estimates, and the difference could be material. Significant items, subject to such estimates and assumptions, include the carrying value of real estate held for investment, real estate held for sale and the allocation of purchase price of real estate assets and intangible assets.

The Partnership regularly assesses whether market events and conditions indicate that it is reasonably possible to recover the carrying amounts of its investments in real estate from future operations and sales. A change in those market events and conditions could have a material effect on the carrying amount of its real estate.

Cash Concentrations of Credit Risk

The Partnership's cash is deposited in one financial institution and at times during the year it may exceed FDIC insurance limits.

Rent Receivables

Credit terms are extended to tenants in the normal course of business. The Partnership performs ongoing credit evaluations of its customers’ financial condition and, generally, requires no collateral.

Rent receivables are recorded at their estimated net realizable value. The Partnership follows a policy of providing an allowance for doubtful accounts; however, based on historical experience, and its evaluation of the current status of receivables, the Partnership is of the belief that such accounts, if any, will be collectible in all material respects and thus an allowance is not necessary. Accounts are considered past due if payment is not made on a timely basis in accordance with the Partnership’s credit terms. Receivables considered uncollectible are written off.

Income Taxes

The income or loss of the Partnership for federal income tax reporting purposes is includable in the income tax returns of the partners. In general, no recognition has been given to income taxes in the accompanying financial statements.

The tax return and the amount of distributable Partnership income or loss are subject to examination by federal and state taxing authorities. If such an examination results in changes to distributable Partnership income or loss, the taxable income of the partners would be adjusted accordingly. Primarily due to its tax status as a partnership, the Partnership has no significant tax uncertainties that require recognition or disclosure. The Partnership is no longer subject to U.S. federal income tax examinations for tax years before 2018, and with few exceptions, is no longer subject to state tax examinations for tax years before 2018.

Revenue Recognition

The Partnership's real estate is leased under net leases, classified as operating leases. The leases provide for base annual rental payments payable in monthly installments. The Partnership recognizes rental income according to the terms of the individual leases. For deferred rents due to COVID-19, the Partnership recognizes the deferred rent related to the month it applies and records a rental receivable. For leases that contain stated rental increases, the increases are recognized in the year in which they are effective. Contingent rental payments are recognized when the contingencies on which the payments are based are satisfied and the rental payments become due under the terms of the leases.

Real Estate Investments

Upon acquisition of real properties, the Partnership records them in the financial statements at cost. The purchase price is allocated to tangible assets, consisting of land and building, and to identified intangible assets and liabilities, which may include the value of above market and below market leases and the value of in-place leases. The allocation of the purchase price is based upon the relative fair value of each component of the property. Although independent appraisals may be used to assist in the determination of fair value, in many cases these values will be based upon management’s assessment of each property, the selling prices of comparable properties and the discounted value of cash flows from the asset.

The fair values of above market and below market in-place leases will be recorded based on the present value (using an interest rate which reflects the risks associated with the leases acquired) of the difference between (i) the contractual amounts to be paid pursuant to the in-place leases and (ii) an estimate of fair market lease rates for the corresponding in-place leases measured over a period equal to the non-cancelable term of the lease including any bargain renewal periods. The above market and below market lease values will be capitalized as intangible lease assets or liabilities. Above market lease values will be amortized as an adjustment of rental income over the remaining term of the respective leases. Below market lease values will be amortized as an adjustment of rental income over the remaining term of the respective leases, including any bargain renewal periods. If a lease were to be terminated prior to its stated expiration, all unamortized amounts of above market and below market in-place lease values relating to that lease would be recorded as an adjustment to rental income.

The fair values of in-place leases will include estimated direct costs associated with obtaining a new tenant, and opportunity costs associated with lost rentals which are avoided by acquiring an in-place lease. Direct costs associated with obtaining a new tenant may include commissions, tenant improvements, and other direct costs and are estimated, in part, by management’s consideration of current market costs to execute a similar lease. These direct costs will be included in intangible lease assets on the balance sheet and will be amortized to expense over the remaining term of the respective leases. The value of opportunity costs will be calculated using the contractual amounts to be paid pursuant to the in-place leases over a market absorption period for a similar lease. These intangibles will be included in intangible lease assets on the balance sheet and will be amortized to expense over the remaining term of the respective leases. If a lease were to be terminated prior to its stated expiration, all unamortized amounts of in-place lease assets relating to that lease would be expensed.

The Partnership tests real estate for recoverability when events or changes in circumstances indicate that the carrying value may not be recoverable. For properties the Partnership will hold and operate, it compares the carrying amount of the property to the estimated probability-weighted future undiscounted cash flows expected to result from the property and its eventual disposition. If the sum of the expected future cash flows is less than the carrying amount of the property, the Partnership recognizes an impairment loss equal to the amount by which the carrying amount of the property exceeds the fair value of the property. For properties held for sale, the Partnership determines whether impairment has occurred by comparing the property’s estimated fair value less cost to sell to its current carrying value. If the carrying value is greater than the net realizable value, an impairment loss is recorded to reduce the carrying value of the property to its net realizable value.

For financial reporting purposes, the buildings owned by the Partnership are depreciated using the straight-line method over an estimated useful life of 25 years. Intangible lease assets are amortized using the straight-line method for financial reporting purposes based on the remaining life of the lease.

The disposition of a property or classification of a property as Real Estate Held for Sale by the Partnership does not represent a strategic shift that will have a major effect on the Partnership’s operations and financial results. Therefore, the results from operating and selling the property are included in continuing operations.

The Partnership accounts for properties owned as tenants-in-common with affiliated entities and/or unrelated third parties using the proportionate consolidation method. Each tenant-in-common owns a separate, undivided interest in the properties. Any tenant-in-common that holds more than a 50% interest does not control decisions over the other tenant-in-common interests. The financial statements reflect only this Partnership's percentage share of the properties' land, building, intangible assets, liabilities, revenues and expenses.

The Partnership's properties are subject to environmental laws and regulations adopted by various governmental entities in the jurisdiction in which the properties are located. These laws could require the Partnership to investigate and remediate the effects of the release or disposal of hazardous materials at these locations if found. For each property, an environmental assessment is completed prior to acquisition. In addition, the lease agreements typically strictly prohibit the production, handling, or storage of hazardous materials (except where incidental to the tenant’s business such as use of cleaning supplies) in violation of applicable law to restrict environmental and other damage. Environmental liabilities are recorded when it is determined the liability is probable and the costs can reasonably be estimated. There were no environmental issues noted or liabilities recorded at December 31, 2021 and 2020.

Fair Value Measurements

As of December 31, 2021 and 2020, the Partnership had no assets or liabilities measured at fair value on a recurring basis or nonrecurring basis.

Income Per Unit

Income per Limited Partnership Unit is calculated based on the weighted average number of Limited Partnership Units outstanding during each period presented. Diluted income per Limited Partnership Unit considers the effect of any potentially dilutive Unit equivalents, of which the Partnership had none for each of the years ended December 31, 2021 and 2020.

Reportable Segments

The Partnership invests in single tenant commercial properties throughout the United States that are net leased to tenants in various industries. Because these net leased properties have similar economic characteristics, the Partnership evaluates operating performance on an overall portfolio basis. Therefore, the Partnership’s properties are classified as one reportable segment.

Recently Adopted Accounting Pronouncements

In April 2020, the Financial Accounting Standards Board (FASB) issued a question-and-answer document (the “Lease Modification Q&A”) focused on the application of lease accounting guidance to lease concessions provided as a result of COVID-19. Under existing lease guidance, the Partnership would have to determine, on a lease by lease basis, if a lease concession was the result of a new arrangement reached with the tenant or if a lease concession was under the enforceable rights and obligations within the existing lease agreement. The Lease Modification Q&A clarifies that entities may elect to not evaluate whether lease-related relief that lessors provide to mitigate the economic effects of COVID-19 on lessees is a lease modification under current lease guidance. Instead, an entity that elects not to evaluate whether a concession directly related to COVID-19 is a modification can then elect whether to apply the modification guidance.

During the year ended December 31, 2020, the Partnership provided lease concessions to certain tenants in response to the impact of COVID-19, in the form of rent deferrals. The Partnership has made an election to account for such lease concessions consistent with how those concessions would be accounted for under lease guidance if enforceable rights and obligations for those concessions had already existed in the leases. This election is available for concessions related to the effects of the COVID-19 pandemic that do not result in a substantial increase in the rights as lessor, including concessions that result in the total payments required by the modified lease being substantially the same as or less than total payments required by the original lease.

Substantially all of the Partnership’s concessions to date provide for a deferral of payments with no substantive changes to the consideration in the original lease. These deferrals affect the timing, but not the amount, of the lease payments. The Partnership is accounting for these deferrals as if no changes to the lease were made. Under this accounting, the Partnership increases its rent receivables as tenant payments accrue and continues to recognize rental income. During the year ended December 31, 2020, the Partnership has entered into lease modifications that deferred $51,584, which was recognized as rental income for those deferred months in 2020. The rent receivable related to these rental deferrals is $4,299 as of December 31, 2021.

Other accounting standards that have been issued or proposed by the FASB are currently not applicable to the Company or are not expected to have a significant impact on the Company’s financial position, results of operations and cash flows.

The Partnership leases its properties to tenants under net leases, classified as operating leases. Under a net lease, the tenant is responsible for real estate taxes, insurance, maintenance, repairs and operating expenses for the property. For some leases, the Partnership is responsible for repairs to the structural components of the building, the roof, and the parking lot. At the time the properties were acquired, the remaining primary lease terms varied from 10 to 18 years. The leases provide the tenants with two to four five-year renewal options subject to the same terms and conditions as the primary term.

The Limited Partners received distributions of $607,594 and $561,596 and the General Partners received distributions of $6,137 and $5,673 for the years, respectively. The Limited Partners' distributions represented $33.70 and $29.89 per Limited Partnership Unit outstanding using 18,029 and 18,791 weighted average Units in 2021 and 2020, respectively. The distributions represented $14.12 and $29.89 per Unit of Net Income and $19.58 and $0 per Unit of contributed capital in 2021 and 2020, respectively.

The Partnership may repurchase Units from Limited Partners who have tendered their Units to the Partnership. Such Units may be acquired at a discount. The Partnership will not be obligated to purchase in any year any number of Units that, when aggregated with all other transfers of Units that have occurred since the beginning of the same calendar year (excluding Permitted Transfers as defined in the Partnership Agreement), would exceed 5% of the total number of Units outstanding on January 1 of such year. In no event shall the Partnership be obligated to purchase Units if, in the sole discretion of the Managing General Partner, such purchase would impair the capital or operation of the Partnership.

On April 1, 2021, the Partnership repurchased a total of 843.97 Units for $610,604 from 36 Limited Partners in accordance with the Partnership Agreement. The Partnership acquired these Units using net sales proceeds. On October 1, 2021, the Partnership repurchased a total of 518.17 Units for $389,248 from 39 Partners. The Partnership acquired these Units using net sales proceeds. The repurchases increase the remaining Limited Partners' ownership interest in the Partnership. As a result of these repurchases and pursuant to the Partnership Agreement, the General Partners received distributions of $10,100 in 2021. During 2020, the Partnership did not repurchase any Units from Limited Partners.

COVID-19 Outbreak [Abstract]

COVID-19 Outbreak [Text Block]

(8)  COVID-19 Outbreak –

During the first quarter of 2020, there was a global outbreak of COVID-19 which continues to adversely impact global commercial activity and has contributed to significant volatility in financial markets. The global impact of the outbreak has been rapidly evolving, and as cases of the virus have continued to be identified in additional countries, many countries have reacted by instituting quarantines, placing restrictions on travel, and limiting hours of operations of non-essential offices and retail centers. Such actions are creating disruption in global supply chains, and adversely impacting a number of industries, such as retail, restaurants and transportation. The outbreak could have a continued adverse impact on economic and market conditions and trigger a period of global economic slowdown. The rapid development and fluidity of this situation precludes any prediction as to the ultimate adverse impact of COVID-19. Nevertheless, COVID19 presents material uncertainty and risk with respect to the Partnership’s performance and financial results, such as the potential negative impact to the tenants of its properties, the potential closure of certain of its properties, increased costs of operations, decrease in values of its properties, changes in law and/or regulation, and uncertainty regarding government and regulatory policy. Up to the date of this filing, the Partnership has entered into rent deferral agreements with two tenants of the six properties owned by the Partnership. In June 2020, the Partnership entered into an agreement with the tenant of the Jared Jewelry store in Auburn Hills, Michigan and Hanover, Maryland to defer base rent in April and May 2020. The tenants started paying the deferred amounts in twelve equal monthly installments beginning on February 1, 2021.

The Partnership has elected not to account for these deferrals of rent as a lease modification under COVID-19 guidance issued by the FASB. Deferred rent of $51,584 was recognized as rental income during the year ended December 31, 2020 and a corresponding rent receivable was recorded. The rent receivable related to these rental deferrals is $4,299 as of December 31, 2021. The Partnership continues to work closely with tenants to determine the best course of action to meet the tenants short-term rental needs during these unprecedented times.

Accounting Policies [Abstract]

Distribution Policy, Members or Limited Partners, Description

During operations, any Net Cash Flow, as defined, which the General Partners determine to distribute will be distributed 90% to the Limited Partners and 10% to the General Partners; provided, however, that such distributions to the General Partners will be subordinated to the Limited Partners first receiving an annual, noncumulative distribution of Net Cash Flow equal to 10% of their Adjusted Capital Contribution, as defined, and, provided further, that in no event will the General Partners receive less than 1% of such Net Cash Flow per annum. Distributions to Limited Partners will be made pro rata by Units. Any Net Proceeds of Sale, as defined, from the sale or financing of properties which the General Partners determine to distribute will, after provisions for debts and reserves, be paid in the following manner: (i) first, 99% to the Limited Partners and 1% to the General Partners until the Limited Partners receive an amount equal to: (a) their Adjusted Capital Contribution plus (b) an amount equal to 10% of their Adjusted Capital Contribution per annum, cumulative but not compounded, to the extent not previously distributed from Net Cash Flow;  (ii) any remaining balance will be distributed 90% to the Limited Partners and 10% to the General Partners. Distributions to the Limited Partners will be made pro rata by Units.

Key Provisions of Operating or Partnership Agreement, Description

For tax purposes, profits from operations, other than profits attributable to the sale, exchange, financing, refinancing or other disposition of property, will be allocated first in the same ratio in which, and to the extent, Net Cash Flow is distributed to the Partners for such year. Any additional profits will be allocated in the same ratio as the last dollar of Net Cash Flow is distributed. Net losses from operations will be allocated 99% to the Limited Partners and 1% to the General Partners. For tax purposes, profits arising from the sale, financing, or other disposition of property will be allocated in accordance with the Partnership Agreement as follows: (i) first, to those partners with deficit balances in their capital accounts in an amount equal to the sum of such deficit balances; (ii) second, 99% to the Limited Partners and 1% to the General Partners until the aggregate balance in the Limited Partners' capital accounts equals the sum of the Limited Partners' Adjusted Capital Contributions plus an amount equal to 10% of their Adjusted Capital Contributions per annum, cumulative but not compounded, to the extent not previously allocated; (iii) third, the balance of any remaining gain will then be allocated 90% to the Limited Partners and 10% to the General Partners. Losses will be allocated 98% to the Limited Partners and 2% to the General Partners.   The General Partners are not required to currently fund a deficit capital balance. Upon liquidation of the Partnership or withdrawal by a General Partner, the General Partners will contribute to the Partnership an amount equal to the lesser of the deficit balances in their capital accounts or 1% of total Limited Partners' and General Partners' capital contributions

Basis of Accounting, Policy [Policy Text Block]

The accounts of the Partnership are maintained on the accrual basis of accounting for both federal income tax purposes and financial reporting purposes.

Use of Estimates, Policy [Policy Text Block]

Management uses estimates and assumptions in preparing these financial statements in accordance with United States Generally Accepted Accounting Principles (US GAAP). Those estimates and assumptions may affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities, and the reported revenues and expenses. Actual results could differ from those estimates, and the difference could be material. Significant items, subject to such estimates and assumptions, include the carrying value of real estate held for investment, real estate held for sale and the allocation of purchase price of real estate assets and intangible assets.

The Partnership regularly assesses whether market events and conditions indicate that it is reasonably possible to recover the carrying amounts of its investments in real estate from future operations and sales. A change in those market events and conditions could have a material effect on the carrying amount of its real estate.

Concentration Risk, Credit Risk, Policy [Policy Text Block]

The Partnership's cash is deposited in one financial institution and at times during the year it may exceed FDIC insurance limits.

Receivable [Policy Text Block]

Credit terms are extended to tenants in the normal course of business. The Partnership performs ongoing credit evaluations of its customers’ financial condition and, generally, requires no collateral.

Rent receivables are recorded at their estimated net realizable value. The Partnership follows a policy of providing an allowance for doubtful accounts; however, based on historical experience, and its evaluation of the current status of receivables, the Partnership is of the belief that such accounts, if any, will be collectible in all material respects and thus an allowance is not necessary. Accounts are considered past due if payment is not made on a timely basis in accordance with the Partnership’s credit terms. Receivables considered uncollectible are written off.

Income Tax, Policy [Policy Text Block]

The income or loss of the Partnership for federal income tax reporting purposes is includable in the income tax returns of the partners. In general, no recognition has been given to income taxes in the accompanying financial statements.

The tax return and the amount of distributable Partnership income or loss are subject to examination by federal and state taxing authorities. If such an examination results in changes to distributable Partnership income or loss, the taxable income of the partners would be adjusted accordingly. Primarily due to its tax status as a partnership, the Partnership has no significant tax uncertainties that require recognition or disclosure. The Partnership is no longer subject to U.S. federal income tax examinations for tax years before 2018, and with few exceptions, is no longer subject to state tax examinations for tax years before 2018

Revenue Recognition, Leases [Policy Text Block]

The Partnership's real estate is leased under net leases, classified as operating leases. The leases provide for base annual rental payments payable in monthly installments. The Partnership recognizes rental income according to the terms of the individual leases. For deferred rents due to COVID-19, the Partnership recognizes the deferred rent related to the month it applies and records a rental receivable. For leases that contain stated rental increases, the increases are recognized in the year in which they are effective. Contingent rental payments are recognized when the contingencies on which the payments are based are satisfied and the rental payments become due under the terms of the leases.

Property, Plant and Equipment, Policy [Policy Text Block]

Upon acquisition of real properties, the Partnership records them in the financial statements at cost. The purchase price is allocated to tangible assets, consisting of land and building, and to identified intangible assets and liabilities, which may include the value of above market and below market leases and the value of in-place leases. The allocation of the purchase price is based upon the relative fair value of each component of the property. Although independent appraisals may be used to assist in the determination of fair value, in many cases these values will be based upon management’s assessment of each property, the selling prices of comparable properties and the discounted value of cash flows from the asset.

The fair values of above market and below market in-place leases will be recorded based on the present value (using an interest rate which reflects the risks associated with the leases acquired) of the difference between (i) the contractual amounts to be paid pursuant to the in-place leases and (ii) an estimate of fair market lease rates for the corresponding in-place leases measured over a period equal to the non-cancelable term of the lease including any bargain renewal periods. The above market and below market lease values will be capitalized as intangible lease assets or liabilities. Above market lease values will be amortized as an adjustment of rental income over the remaining term of the respective leases. Below market lease values will be amortized as an adjustment of rental income over the remaining term of the respective leases, including any bargain renewal periods. If a lease were to be terminated prior to its stated expiration, all unamortized amounts of above market and below market in-place lease values relating to that lease would be recorded as an adjustment to rental income.

The fair values of in-place leases will include estimated direct costs associated with obtaining a new tenant, and opportunity costs associated with lost rentals which are avoided by acquiring an in-place lease. Direct costs associated with obtaining a new tenant may include commissions, tenant improvements, and other direct costs and are estimated, in part, by management’s consideration of current market costs to execute a similar lease. These direct costs will be included in intangible lease assets on the balance sheet and will be amortized to expense over the remaining term of the respective leases. The value of opportunity costs will be calculated using the contractual amounts to be paid pursuant to the in-place leases over a market absorption period for a similar lease. These intangibles will be included in intangible lease assets on the balance sheet and will be amortized to expense over the remaining term of the respective leases. If a lease were to be terminated prior to its stated expiration, all unamortized amounts of in-place lease assets relating to that lease would be expensed.

The Partnership tests real estate for recoverability when events or changes in circumstances indicate that the carrying value may not be recoverable. For properties the Partnership will hold and operate, it compares the carrying amount of the property to the estimated probability-weighted future undiscounted cash flows expected to result from the property and its eventual disposition. If the sum of the expected future cash flows is less than the carrying amount of the property, the Partnership recognizes an impairment loss equal to the amount by which the carrying amount of the property exceeds the fair value of the property. For properties held for sale, the Partnership determines whether impairment has occurred by comparing the property’s estimated fair value less cost to sell to its current carrying value. If the carrying value is greater than the net realizable value, an impairment loss is recorded to reduce the carrying value of the property to its net realizable value.

For financial reporting purposes, the buildings owned by the Partnership are depreciated using the straight-line method over an estimated useful life of 25 years. Intangible lease assets are amortized using the straight-line method for financial reporting purposes based on the remaining life of the lease.

The disposition of a property or classification of a property as Real Estate Held for Sale by the Partnership does not represent a strategic shift that will have a major effect on the Partnership’s operations and financial results. Therefore, the results from operating and selling the property are included in continuing operations.

The Partnership accounts for properties owned as tenants-in-common with affiliated entities and/or unrelated third parties using the proportionate consolidation method. Each tenant-in-common owns a separate, undivided interest in the properties. Any tenant-in-common that holds more than a 50% interest does not control decisions over the other tenant-in-common interests. The financial statements reflect only this Partnership's percentage share of the properties' land, building, intangible assets, liabilities, revenues and expenses.

The Partnership's properties are subject to environmental laws and regulations adopted by various governmental entities in the jurisdiction in which the properties are located. These laws could require the Partnership to investigate and remediate the effects of the release or disposal of hazardous materials at these locations if found. For each property, an environmental assessment is completed prior to acquisition. In addition, the lease agreements typically strictly prohibit the production, handling, or storage of hazardous materials (except where incidental to the tenant’s business such as use of cleaning supplies) in violation of applicable law to restrict environmental and other damage. Environmental liabilities are recorded when it is determined the liability is probable and the costs can reasonably be estimated. There were no environmental issues noted or liabilities recorded at December 31, 2021 and 2020.

Fair Value of Financial Instruments, Policy [Policy Text Block]

As of December 31, 2021 and 2020, the Partnership had no assets or liabilities measured at fair value on a recurring basis or nonrecurring basis.

Earnings Per Share, Policy [Policy Text Block]

Income per Limited Partnership Unit is calculated based on the weighted average number of Limited Partnership Units outstanding during each period presented. Diluted income per Limited Partnership Unit considers the effect of any potentially dilutive Unit equivalents, of which the Partnership had none for each of the years ended December 31, 2021 and 2020

Segment Reporting, Policy [Policy Text Block]

The Partnership invests in single tenant commercial properties throughout the United States that are net leased to tenants in various industries. Because these net leased properties have similar economic characteristics, the Partnership evaluates operating performance on an overall portfolio basis. Therefore, the Partnership’s properties are classified as one reportable segment

New Accounting Pronouncements, Policy [Policy Text Block]

In April 2020, the Financial Accounting Standards Board (FASB) issued a question-and-answer document (the “Lease Modification Q&A”) focused on the application of lease accounting guidance to lease concessions provided as a result of COVID-19. Under existing lease guidance, the Partnership would have to determine, on a lease by lease basis, if a lease concession was the result of a new arrangement reached with the tenant or if a lease concession was under the enforceable rights and obligations within the existing lease agreement. The Lease Modification Q&A clarifies that entities may elect to not evaluate whether lease-related relief that lessors provide to mitigate the economic effects of COVID-19 on lessees is a lease modification under current lease guidance. Instead, an entity that elects not to evaluate whether a concession directly related to COVID-19 is a modification can then elect whether to apply the modification guidance.

During the year ended December 31, 2020, the Partnership provided lease concessions to certain tenants in response to the impact of COVID-19, in the form of rent deferrals. The Partnership has made an election to account for such lease concessions consistent with how those concessions would be accounted for under lease guidance if enforceable rights and obligations for those concessions had already existed in the leases. This election is available for concessions related to the effects of the COVID-19 pandemic that do not result in a substantial increase in the rights as lessor, including concessions that result in the total payments required by the modified lease being substantially the same as or less than total payments required by the original lease.

Substantially all of the Partnership’s concessions to date provide for a deferral of payments with no substantive changes to the consideration in the original lease. These deferrals affect the timing, but not the amount, of the lease payments. The Partnership is accounting for these deferrals as if no changes to the lease were made. Under this accounting, the Partnership increases its rent receivables as tenant payments accrue and continues to recognize rental income. During the year ended December 31, 2020, the Partnership has entered into lease modifications that deferred $51,584, which was recognized as rental income for those deferred months in 2020. The rent receivable related to these rental deferrals is $4,299 as of December 31, 2021.

Other accounting standards that have been issued or proposed by the FASB are currently not applicable to the Company or are not expected to have a significant impact on the Company’s financial position, results of operations and cash flows.
