FORWARD-LOOKING STATEMENTS

The Private Securities Litigation Reform Act of 1995 provides a “safe harbor” for forward-looking statements in certain circumstances. Certain information included in this Annual Report contains or may contain information that is forward-looking within the meaning of the federal securities laws, including, without limitation, statements regarding the Partnership’s ability to maintain current or meet projected occupancy, rental rates and property operating results and the effect of redevelopments. Actual results may differ materially from those described in these forward-looking statements and, in addition, may be affected by a variety of risks and factors, some of which are beyond the Partnership’s control, including, without limitation: financing risks, including the availability and cost of financing and the risk that the Partnership’s cash flows from operations may be insufficient to meet required payments of principal and interest; natural disasters and severe weather such as hurricanes; national and local economic conditions, including the pace of job growth and the level of unemployment; energy costs; the terms of governmental regulations that affect the Partnership’s property and interpretations of those regulations; the competitive environment in which the Partnership operates; real estate risks, including fluctuations in real estate values and the general economic climate in local markets and competition for residents in such markets; insurance risk, including the cost of insurance; litigation, including costs associated with prosecuting or defending claims and any adverse outcomes; and possible environmental liabilities, including costs, fines or penalties that may be incurred due to necessary remediation of contamination of properties presently owned or previously owned by the Partnership. Readers should carefully review the Partnership’s financial statements and the notes thereto, as well as the other documents the Partnership files from time to time with the Securities and Exchange Commission.

PART I

Item 1.    Business

National Property Investors 6 (the "Partnership" or "Registrant") is a California limited partnership formed on October 15, 1982. The Partnership is engaged in the business of operating and holding real estate properties for investment. NPI Equity Investments, Inc., a Florida corporation, became the Partnership's managing general partner (the "Managing General Partner" or "NPI Equity") on June 21, 1991. The Managing General Partner is a subsidiary of Apartment Investment and Management Company ("Aimco"), a publicly traded real estate investment trust. The Partnership Agreement provides that the Partnership is to terminate on December 31, 2022, unless terminated prior to such date.

The Partnership, through its public offering of limited partnership units, sold 109,600 units aggregating $54,800,000. The general partner contributed capital in the amount of $1,000 for a 1% interest in the Partnership. Since its initial offering, the Partnership has not received, nor are limited partners required to make, additional capital contributions. The Partnership currently owns and operates one apartment complex located in Maryland.

The Partnership has no full time employees. Management and administrative services are provided by the Managing General Partner and by agents retained by the Managing General Partner. An affiliate of the Managing General Partner provided such property management services for the years ended December 31, 2014 and 2013.

A further description of the Partnership's business is included in "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations" included in this Form 10-K.

Item 1A. Risk Factors

Not applicable.

Item 2.    Property

The following table sets forth the Partnership's investment in property:

Property	Date of Purchase	Type of Ownership	Use
Colony at Kenilworth Apartments	03/15/84	Fee ownership, subject to first	Apartment
Towson, Maryland		and second mortgages	383 units

On February 2, 2015, the Partnership entered into a sale contract with a third party relating to the sale of Colony at Kenilworth Apartments. The sale is projected to close on March 31, 2015 with a sales price of $44,200,000. The Partnership has determined that certain held for sale criteria have not been met at December 31, 2014 and therefore continues to report the assets and liabilities of Colony at Kenilworth Apartments as held for investment and its operations as continuing operations.

Schedule of Property

Set forth below for the Partnership's investment property is the gross carrying value, accumulated depreciation, depreciable life, method of depreciation and Federal tax basis.

Property	Gross Carrying Value		Accumulated Depreciation		Depreciable Life	Method of Depreciation	Federal Tax Basis
	(in thousands)						(in thousands)
Colony at Kenilworth
Apartments	$	31,945	$	24,090	5-30 yrs	S/L	$	7,573

See "Note A – Organization and Summary of Significant Accounting Policies" to the financial statements included in "Item 8. Financial Statements and Supplementary Data" for a description of the Partnership's depreciation and capitalization policies.

Schedule of Property Indebtedness

The following table sets forth certain information relating to the loans encumbering the Partnership's property.

Property	Principal Balance at December 31, 2014		Fixed Interest Rate	Period Amortized	Maturity Date	Principal Balance Due at Maturity (1)
	(in thousands)					(in thousands)
Colony at Kenilworth

	$	22,638				$	19,866

(1) See “Note B - Mortgage Notes Payable” to the financial statements included in "Item 8. Financial Statements and Supplementary Data" for information with respect to the Partnership's ability to prepay the loans and other specific details about the loans.

Schedule of Rental Rates and Occupancy

Average annual rental rates and occupancy for 2014 and 2013 for the property were as follows:

Property	Average Annual Rental Rate				Average Annual Occupancy
	(per unit)
	2014		2013		2014		2013
Colony at Kenilworth Apartments	$	13,197	$	12,820	93	%	90	%

The real estate industry is highly competitive. The Partnership’s property is subject to competition from other residential apartment complexes in the area. The Managing General Partner believes that the property is adequately insured. The property is an apartment complex which leases units for terms of one year or less. No tenant leases 10% or more of the available rental space. The property is in good physical condition, subject to normal depreciation and deterioration as is typical for an asset of this type and age.

Schedule of Real Estate Taxes and Rate

Real estate taxes and rate in 2014 for the property were as follows:

	2014	2014
	Billing	Rate
	(in thousands)
Colony at Kenilworth Apartments (1)	$360	1.20%

(1)    Property’s tax year is not on a calendar year basis.

Capital Improvements

During the year ended December 31, 2014, the Partnership completed approximately $861,000 of capital improvements at Colony at Kenilworth Apartments, consisting primarily of retaining walls, building improvements, air conditioning upgrades and water heater, appliance and floor covering replacements. These improvements were funded from operating cash flow. The Partnership regularly evaluates the capital improvement needs of the property. While the Partnership has no material commitments for property improvements and replacements, certain routine capital expenditures are anticipated during 2015. Such capital expenditures will depend on the physical condition of the property as well as anticipated cash flow generated by the property.

Capital expenditures will be incurred only if cash is available from operations, Partnership reserves or advances from AIMCO Properties, L.P., although AIMCO Properties, L.P. does not have an obligation to fund such advances. To the extent that capital improvements are completed, the Partnership's distributable cash flow, if any, may be adversely affected at least in the short term.

Item 3.    Legal Proceedings

None.

Item 4.    Mine Safety Disclosures

Not applicable.

PART II

Item 5. Market for the Registrant’s Common Equity, Related Security Holder Matters and Issuer Purchases of Equity Securities

The Partnership, a publicly-held limited partnership, offered and sold 109,600 Limited Partnership Units (the “Units”) aggregating $54,800,000. As of December 31, 2014, the Partnership had 109,446 Units outstanding held by 1,874 limited partners of record. Affiliates of the Managing General Partner owned 76,622 Units or 70.01% at December 31, 2014. No public trading market has developed for the Units, and it is not anticipated that such a market will develop in the future.

There were no distributions made by the Partnership during the years ended December 31, 2014 and 2013. Future cash distributions will depend on the levels of cash generated from operations and the timing of the debt maturities, property sale and/or refinancings. The Partnership's cash available for distribution is reviewed on a monthly basis. In light of the significant amounts accrued and payable to affiliates of the Managing General Partner at December 31, 2014, there can be no assurance that the Partnership will generate sufficient funds from operations, after planned capital expenditures and repayment of amounts due to affiliates, to permit any distributions to its partners in 2015 or subsequent periods. See “Item 2. Property – Capital Improvements” for information relating to anticipated capital expenditures at the property.

In addition to its indirect ownership of the Managing General Partner interest in the Partnership, Aimco and its affiliates owned 76,622 Units in the Partnership representing 70.01% of the outstanding Units at December 31, 2014. A number of these Units were acquired pursuant to tender offers made by Aimco or its affiliates. It is possible that Aimco or its affiliates will acquire additional Units in exchange for cash or a combination of cash and units in AIMCO Properties, L.P., the operating partnership of Aimco, either through private purchases or tender offers. Pursuant to the Partnership Agreement, Unit holders holding a majority of the Units are entitled to take action with respect to a variety of matters that include, but are not limited to, voting on certain amendments to the Partnership Agreement and voting to remove the Managing General Partner. As a result of its ownership of 70.01% of the outstanding Units, Aimco and its affiliates are in a position to influence all such voting decisions with respect to the Partnership. However, with respect to the 47,624 Units acquired on January 19, 1996, AIMCO IPLP, L.P. ("IPLP"), an affiliate of the Managing General Partner and of Aimco, agreed to vote such Units: (i) against any increase in compensation payable to the Managing General Partner or to its affiliates; and (ii) on all other matters submitted by it or its affiliates, in proportion to the vote cast by third party unitholders.Except for the foregoing, no other limitations are imposed on IPLP's, Aimco's or any other affiliates' right to vote each Unit held. Although the Managing General Partner owes fiduciary duties to the limited partners of the Partnership, the Managing General Partner also owes fiduciary duties to Aimco as its sole stockholder. As a result, the duties of the Managing General Partner, as Managing General Partner, to the Partnership and its limited partners may come into conflict with the duties of the Managing General Partner to Aimco as its sole stockholder.

Item 6.    Selected Financial Data

Not applicable.

Item 7.    Management's Discussion and Analysis of Financial Condition and Results of Operations

This item should be read in conjunction with the financial statements and other items contained elsewhere in this report.

The Partnership’s financial results depend upon a number of factors including the ability to attract and maintain residents at the investment property, interest rates on mortgage loans, costs incurred to operate the investment property, general economic conditions and weather. As part of the ongoing business plan of the Partnership, the Managing General Partner monitors the rental market environment of its investment property to assess the feasibility of increasing rents, maintaining or increasing occupancy levels and protecting the Partnership from increases in expenses. As part of this plan, the Managing General Partner attempts to protect the Partnership from the burden of inflation-related increases in expenses by increasing rents and maintaining a high overall occupancy level. However, the Managing General Partner may use rental concessions and rental rate reductions to offset softening market conditions; accordingly, there is no guarantee that the Managing General Partner will be able to sustain such a plan. Further, a number of factors that are outside the control of the Partnership such as the local economic climate and weather can adversely or positively affect the Partnership’s financial results.

Results of Operations

The Partnership’s net loss for the years ended December 31, 2014 and 2013 was approximately $877,000 and $1,423,000, respectively. The decrease in net loss is due to an increase in total revenues and a decrease in total expenses.

Total revenues increased primarily due to an increase in rental income partially offset by a decrease in other income. Rental income increased due to increases in occupancy and the average rental rate and a decrease in bad debt expense.Other income decreased due to decreases in lease cancellation fees and cleaning and damage fees.

Total expenses decreased due to a decrease in depreciation expense, partially offset by an increase in general and administrative expense. Operating, interest and property tax expenses remained relatively constant for the comparable periods. Depreciation expense decreased due to assets becoming fully depreciated during 2013.

General and administrative expenses increased due to legal and other administrative costs related to a potential sale of the investment property. Also included in general and administrative expenses for the years ended December 31, 2014 and 2013 are management reimbursements to the Managing General Partner as allowed under the Partnership Agreement, costs associated with the quarterly and annual communications with investors and regulatory agencies and the annual audit required by the Partnership Agreement.

In April 2014, Colony at Kenilworth Apartments sustained damages from a fire which affected three apartment units. The estimated damages are approximately $160,000 and the Partnership expects to receive insurance proceeds. During the year ended December 31, 2014, the Partnership incurred reconstruction costs of approximately $133,000 of which approximately $74,000 were repair and clean-up costs that are included in operating expenses. The Partnership does not expect to record a loss from this event.

Liquidity and Capital Resources

At December 31, 2014, the Partnership had cash and cash equivalents of approximately $215,000, compared to approximately $261,000 at December 31, 2013. Cash and cash equivalents decreased approximately $46,000 due to approximately $864,000 of cash used in investing activities, partially offset by approximately$678,000 and $140,000 of cash provided by operating and financing activities, respectively. Cash used in investing activities consisted of property improvements and replacements. Cash provided by financing activities consisted of advances received from AIMCO Properties, L.P., partially offset by principal payments made on the mortgages encumbering the Partnership’s investment property.

The Partnership may receive advances of funds from AIMCO Properties, L.P., an affiliate of the Managing General Partner and the holder of a majority of the beneficial interest of the Partnership. During the years ended December 31, 2014 and 2013, AIMCO Properties, L.P. advanced the Partnership approximately $550,000 and $525,000, respectively, to fund real estate taxes at the Partnership’s investment property. The advances bear interest at the prime rate plus 2% (5.25% at December 31, 2014) per annum. Interest expense was approximately $587,000 and $534,000 for the years ended December 31, 2014 and 2013, respectively. During the year ended December 31, 2014, the Partnership paid $130,000 of accrued interest. At December 31, 2014 and 2013, the total advances and accrued interest owed to AIMCO Properties, L.P. was approximately $11,782,000 and $10,775,000, respectively, and is included in due to affiliates. The Partnership may receive additional advances of funds from

AIMCO Properties, L.P. although AIMCO Properties, L.P. is not obligated to provide such advances. For more information on AIMCO Properties, L.P., including copies of its audited balance sheet, please see its reports filed with the Securities and Exchange Commission.

The sufficiency of existing liquid assets to meet future liquidity and capital expenditure requirements is directly related to the level of capital expenditures required at the investment property to adequately maintain the physical asset and other operating needs of the Partnership and to comply with Federal, state, and local legal and regulatory requirements. The Managing General Partner monitors developments in the area of legal and regulatory compliance. The Partnership regularly evaluates the capital improvement needs of the property. While the Partnership has no material commitments for property improvements and replacements, certain routine capital expenditures are anticipated during 2015. Such capital expenditures will depend on the physical condition of the property as well as anticipated cash flow generated by the property. Capital expenditures will be incurred only if cash is available from operations, Partnership reserves or advances from AIMCO Properties, L.P., although AIMCO Properties, L.P. does not have an obligation to fund such advances. To the extent that capital improvements are completed, the Partnership's distributable cash flow, if any, may be adversely affected at least in the short term.

The Partnership’s assets are thought to be generally sufficient for any near-term needs (exclusive of capital improvements and repayment of advances from affiliates). If cash flows are insufficient for the Partnership to meet its current obligations, the Partnership may request additional advances of funds from AIMCO Properties, L.P., although AIMCO Properties, L.P. is not obligated to provide such advances. The mortgage indebtedness encumbering Colony at Kenilworth Apartments of approximately $22,638,000 matures in July 2019 and July 2021, at which time balloon payments of approximately $10,415,000 and $9,451,000, respectively, will be due. The Managing General Partner will attempt to refinance such indebtedness and/or sell the property prior to such maturity dates. If the property cannot be refinanced or sold for a sufficient amount, the Partnership will risk losing such property through foreclosure.

There were no distributions made by the Partnership during the years ended December 31, 2014 and 2013. Future cash distributions will depend on the levels of cash generated from operations and the timing of the debt maturities, property sale and/or refinancings. The Partnership's cash available for distribution is reviewed on a monthly basis. In light of the significant amounts accrued and payable to affiliates of the Managing General Partner at December 31, 2014, there can be no assurance that the Partnership will generate sufficient funds from operations, after planned capital expenditures and repayment of amounts due to affiliates, to permit any distributions to its partners in 2015 or subsequent periods.

On February 2, 2015, the Partnership entered into a sale contract with a third party relating to the sale of Colony at Kenilworth Apartments. The sale is projected to close on March 31, 2015 with a sales price of $44,200,000. The Partnership has determined that certain held for sale criteria have not been met at December 31, 2014 and therefore continues to report the assets and liabilities of Colony at Kenilworth Apartments as held for investment and its operations as continuing operations.

Critical Accounting Policies and Estimates

A summary of the Partnership’s significant accounting policies is included in "Note A – Organization and Summary of Significant Accounting Policies" which is included in the financial statements in "Item 8. Financial Statements and Supplementary Data". The ManagingGeneral Partner believes that the consistent application of these policies enables the Partnership to provide readers of the financial statements with useful and reliable information about the Partnership’s operating results and financial condition. The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires the Partnership to make estimates and assumptions. These estimates and assumptions affect the reported amounts of assets and liabilities at the date of the financial statements as well as reported amounts of revenues and expenses during the reporting period. Actual results could differ from these estimates. Judgments and assessments of uncertainties are required in applying the Partnership’s accounting policies in many areas. The Partnership believes that of its significant accounting policies, the following may involve a higher degree of judgment and complexity.

Impairment of Long-Lived Asset

Investment property is recorded at cost, less accumulated depreciation, unless the carrying amount of the asset is not recoverable. If events or circumstances indicate that the carrying amount of the property may not be recoverable, the Partnership will make an assessment of its recoverability by comparing the carrying amount to the Partnership’s estimate of the undiscounted future cash flows, excluding interest charges, of the property. If the carrying amount exceeds the estimated aggregate undiscounted future cash flows, the Partnership would recognize an impairment loss to the extent the carrying amount exceeds the estimated fair value of the property.

Real property investment is subject to varying degrees of risk. Several factors may adversely affect the economic performance and value of the Partnership’s investment property. These factors include, but are not limited to, general economic climate; competition from other apartment communities and other housing options; local conditions, such as loss of jobs or an increase in the supply of apartments that might adversely affect apartment occupancy or rental rates; changes in governmental regulations and the related cost of compliance; increases in operating costs (including real estate taxes) due to inflation and other factors, which may not be offset by increased rents; changes in tax laws and housing laws, including the enactment of rent control laws or other laws regulating multi-family housing; and changes in interest rates and the availability of financing. Any adverse changes in these and other factors could cause an impairment of the Partnership’s asset.

Revenue Recognition

The Partnership generally leases apartment units for twelve-month terms or less. The Partnership will offer rental concessions during particularly slow months or in response to heavy competition from other similar complexes in the area. Rental income attributable to leases, net of any concessions, is recognized on a straight-line basis over the term of the lease. The Partnership evaluates all accounts receivable from residents and establishes an allowance, after the application of security deposits, for accounts greater than 30 days past due on current residents and all receivables due from former residents.

The Partners

National Property Investors 6

We have audited the accompanying balance sheets of National Property Investors 6 as of December 31, 2014 and 2013, and the related statements of operations, changes in partners' deficit, and cash flows for each of the two years in the period ended December 31, 2014. These financial statements are the responsibility of the Partnership's management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. We were not engaged to perform an audit of the Partnership’s internal control over financial reporting. Our audit included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, 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. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management and evaluating the overall financial statement presentation. We believe that our audits provides a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of National Property Investors 6 at December 31, 2014 and 2013, and the results of its operations and its cash flows for each of the two years in the period ended December 31, 2014, in conformity with U.S. generally accepted accounting principles.

NOTES TO FINANCIAL STATEMENTS

December 31, 2014

Note A – Organization and Summary of Significant Accounting Policies

Organization

National Property Investors 6 (the "Partnership" or "Registrant") is a California limited partnership formed on October 15, 1982. The Partnership is engaged in the business of operating and holding one apartment property located in Towson, Maryland for investment. NPI Equity Investments, Inc., a Florida corporation, became the Partnership's managing general partner (the "Managing General Partner" or "NPI Equity") on June 21, 1991. The Managing General Partner is a subsidiary of Apartment Investment and Management Company ("Aimco"), a publicly traded real estate investment trust. The partnership agreement provides that the Partnership is to terminate on December 31, 2022.

Subsequent Events

The Partnership’s management evaluated subsequent events through the time this Annual Report on Form 10-K was filed.

Reclassifications

Certain reclassifications have been made to the 2013 balances to conform to the 2014 presentation.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates.

Abandoned Units

During the years ended December 31, 2014 and 2013, the number of limited partnership units (the “Units”) decreased by 50 and 28 Units, respectively, due to limited partners abandoning their Units. In abandoning his or her Units, a limited partner relinquishes all right, title and interest in the Partnership as of the date of the abandonment.

Net Loss Per Limited Partnership Unit

At December 31, 2014 and 2013, the Partnership had outstanding 109,446 and 109,496 Units, respectively. Net loss per Limited Partnership Unit is computed by dividing net loss allocated to the limited partners by the number of Units outstanding at the beginning of the fiscal year. The number of Units used was 109,496 and 109,524 Units for the years ended December 31, 2014 and 2013, respectively.

Allocation of Income, Loss and Distributions

Net income, net loss and distributions of cash of the Partnership are allocated between the general and limited partners in accordance with the provisions of the Partnership Agreement.

Note A – Organization and Summary of Significant Accounting Policies (continued)

Fair Value of Financial Statements

Financial Accounting Standards Board Accounting Standards Codification Topic 825, “Financial Instruments”, requires disclosure of fair value information about financial instruments, whether or not recognized in the balance sheet, for which it is practicable to estimate fair value. Fair value is defined as the amount at which the instruments could be exchanged in a current transaction between willing parties, other than in a forced or liquidation sale. The Partnership is required to classify these fair value measurements into one of three categories, based on the nature of the inputs used in the fair value measurement. Level 1 of the hierarchy includes fair value measurements based on unadjusted quoted prices in active markets for identical assets or liabilities the Partnership can access at the measurement date. Level 2 includes fair value measurements based on inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly. Level 3 includes fair value measurements based on unobservable inputs. The classification of fair value measurements is subjective and generally accepted accounting principles requires the Partnership to disclose more detailed information regarding those fair value measurements classified within the lower levels of the hierarchy. The Partnership believes that the carrying amount of its financial instruments (except for mortgage notes payable) approximates their fair value due to the short-term maturity of these instruments. The Partnership estimates the fair value of its mortgage notes payable by discounting future cash flows using a discount rate commensurate with that currently believed to be available to the Partnership for similar term, mortgage notes payable. The Partnership has classified this fair value measurement within Level 2 of the fair value hierarchy. At December 31, 2014, the fair value of the Partnership's mortgage notes payable at the Partnership's incremental borrowing rate was approximately $25,657,000.

Cash and Cash Equivalents

Cash and cash equivalents include cash on hand and cash in banks. At certain times, the amount of cash deposited at a bank may exceed the limit on insured deposits. Cash balances included approximately $215,000 and $261,000 at December 31, 2014 and 2013, respectively, that are maintained by an affiliated management company on behalf of affiliated entities in cash concentration accounts.

Tenant Security Deposits

The Partnership requires security deposits from lessees for the duration of the lease and such deposits are included in receivables and deposits. The security deposits are refunded when the tenant vacates, provided the tenant has not damaged the space and is current on rental payments.

Depreciation

Depreciation is provided by the straight-line method over the estimated lives of the apartment property and related personal property. For Federal income tax purposes, the modified accelerated cost recovery method is used for depreciation of

(1) real property over 27.5 years and (2) personal property additions over 5 years.

Deferred Costs

Loan costs of approximately $649,000 at both December 31, 2014 and 2013, less accumulated amortization of approximately $427,000 and $388,000, respectively, are included in other assets and are amortized over the term of the related loan agreements. The total amortization expense for each of the years ended December 31, 2014 and 2013 was approximately $39,000 and is included in interest expense. Amortization expense is expected to be approximately $39,000 for each of the years 2015 through 2018 and approximately $31,000 for 2019.

Leasing commissions and other direct costs incurred in connection with successful leasing efforts are deferred and amortized over the terms of the related leases. Amortization of these costs is included in operating expenses.

Note A – Organization and Summary of Significant Accounting Policies (continued)

Leases

The Partnership generally leases apartment units for twelve-month terms or less. The Partnership will offer rental concessions during particularly slow months or in response to heavy competition from other similar complexes in the area. Rental income attributable to leases, net of any concessions, is recognized on a straight-line basis over the term of the lease. The Partnership evaluates all accounts receivable from residents and establishes an allowance, after the application of security deposits, for accounts greater than 30 days past due on current residents and all receivables due from former residents.

Investment Property

Investment property consists of one apartment complex and is stated at cost, less accumulated depreciation, unless the carrying amount of the asset is not recoverable. The Partnership capitalizes costs incurred in connection with capital additions activities, including redevelopment and construction projects, other tangible property improvements and replacements of existing property components. Included in these capitalized costs are payroll costs associated with time spent by site employees in connection with capital additions activities at the property level. The Partnership capitalizes interest, property taxes and insurance during periods in which redevelopment and construction projects are in progress. The Partnership did not capitalize any costs related to interest, property taxes or insurance during the years ended December 31, 2014 and 2013. Capitalized costs are depreciated over the estimated useful life of the asset. The Partnership charges to expense as incurred costs including ordinary repairs, maintenance and resident turnover costs.

If events or circumstances indicate that the carrying amount of the property may not be recoverable, the Partnership will make an assessment of its recoverability by comparing the carrying amount to the Partnership’s estimate of the undiscounted future cash flows, excluding interest charges, of the property. If the carrying amount exceeds the estimated aggregate undiscounted future cash flows, the Partnership would recognize an impairment loss to the extent the carrying amount exceeds the estimated fair value of the property. No adjustments for impairment of value were necessary for the years ending December 31, 2014 and 2013.

Segment Reporting

ASC Topic 280-10, “Segment Reporting”, established standards for the way that public business enterprises report information about operating segments in annual financial statements and requires that those enterprises report selected information about operating segments in interim financial reports. ASC Topic 280-10 also established standards for related disclosures about products and services, geographic areas, and major customers. As defined in ASC Topic 280-10, the Partnership has only one reportable segment.

Advertising Costs

Advertising costs of approximately $85,000 for the years ended December 31, 2014 and 2013, respectively, were charged to expense as incurred and are included in operating expenses.

Recent Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board (“FASB”) and the International Accounting Standards Board issued their final standard on revenue from contracts with customers which was issued by the FASB as Accounting Standards Update 2014-09, Revenue from Contracts with Customers, or ASU 2014-09.  ASU 2014-09, which establishes a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers, supersedes most current generally accepted accounting principles applicable to revenue recognition and converges U.S. and international accounting standards in this area. The core principle of the new guidance is that revenue shall only be recognized when an entity has transferred control of goods or services to a customer and for an amount reflecting the consideration to which the entity expects to be entitled for such exchange.

ASU 2014-09 is effective for public entities for annual reporting periods beginning after December 15, 2016, with no early adoption permitted, and allows for full retrospective adoption applied to all periods presented or modified retrospective adoption with the cumulative effect of initially applying the standard recognized at the date of initial application.  The Partnership has not yet determined the effect ASU 2014-09 will have on its financial statements.

Note A – Organization and Summary of Significant Accounting Policies(continued)

In August 2014, The FASB issued Accounting Standards Update 2014-15, Presentation of Financial Statements-Going Concern, or ASU 2014-15. ASU 2014-15 requires management to evaluate whether there are conditions and events, considered in the aggregate, that raise substantial doubt about the entity’s ability to continue as a going concern within one year after the date that the financial statements are issued.

This evaluation should include consideration of whether it is probable that the entity will be unable to meet its obligations as they become due within one year after the date that the financial statements are issued, and should initially take into consideration the potential mitigating effect of management’s plans that have not been fully implemented as of the date that the financial statements are issued (e.g. plans to raise capital, borrow money, restructure debt, etc). Entities must disclose the principal conditions or events that raise substantial doubt about the entity’s ability to continue as a going concern, as well as management’s evaluation of those conditions and potential plans for mitigation.

ASU 2014-15 is effective for all entities for annual reporting periods ending after December 15, 2016, and interim periods thereafter, with early adoption permitted. The Partnership does not expect ASU 2014-15 to have a material effect on its financial statements.

Note B – Mortgage Notes Payable

The principal terms of mortgage notes payable are as follows:

(in thousands)
Property	Principal Balance at December 31, 2014		Principal Balance at December 31, 2013		Monthly Payment Including Interest		Stated Interest Rate	Maturity Date	Principal Balance Due at Maturity

The mortgage notes payable are fixed rate mortgages that are nonrecourse and are secured by pledge of the Partnership's investment property and by a pledge of revenue from the investment property. The mortgage notes payable include prepayment penalties if repaid prior to maturity. Further, the property may not be sold subject to existing indebtedness.

Note C – Income Taxes

The Partnership is classified as a partnership for Federal income tax purposes. Accordingly, no provision for income taxes is made in the financial statements of the Partnership. Taxable income or loss of the Partnership is reported in the income tax returns of its partners.

The following is a reconciliation of reported net loss and Federal taxable (loss) income (in thousands, except per unit data):

Note D – Transactions with Affiliated Parties

The Partnership has no employees and depends on the Managing General Partner and its affiliates for the management and administration of all Partnership activities. The Partnership Agreement provides for certain payments to affiliates for services and as reimbursement of certain expenses incurred by affiliates on behalf of the Partnership.

Affiliates of the Managing General Partner receive 5% of gross receipts from the Partnership's property as compensation for providing property management services. The Partnership paid to such affiliates approximately $260,000 and $247,000 for the years ended December 31, 2014 and 2013, respectively, which are included in operating expenses.

Affiliates of the Managing General Partner charged the Partnership for reimbursement of accountable administrative expenses amounting to approximately $116,000 and $139,000 for the years ended December 31, 2014 and 2013, respectively, which is included in general and administrative expenses and investment property. The portion of these reimbursements included in investment property for the years ended December 31, 2014 and 2013 are construction management services provided by an affiliate of the Managing General Partner of approximately $80,000 and $103,000, respectively. At December 31, 2013, approximately $163,000 of reimbursements were due to the Managing General Partner and are included in due to affiliates.

Note D – Transactions with Affiliated Parties(continued)

For services relating to the administration of the Partnership and operation of the Partnership's property, the Managing General Partner is entitled to receive payment for non-accountable expenses up to a maximum of $150,000 per year, based upon the number of Partnership units sold, subject to certain limitations. No such reimbursements were made during the years ended December 31, 2014 or 2013.

As compensation for services rendered in managing the Partnership, the Managing General Partner is entitled to receive Partnership management fees in conjunction with distributions of cash from operations, subject to certain limitations. No such Partnership management fees were earned or paid during the years ended December 31, 2014 or 2013.

The Partnership may receive advances of funds from AIMCO Properties, L.P., an affiliate of the Managing General Partner and the holder of a majority of the beneficial interest of the Partnership. During the years ended December 31, 2014 and 2013, AIMCO Properties, L.P. advanced the Partnership approximately $550,000 and $525,000, respectively, to fund real estate taxes at the Partnership’s investment property. The advances bear interest at the prime rate plus 2% (5.25% at December 31, 2014) per annum. Interest expense was approximately $587,000 and $534,000 for the years ended December 31, 2014 and 2013, respectively. During the year ended December 31, 2014, the Partnership paid $130,000 of accrued interest. At December 31, 2014 and 2013, the total advances and accrued interest owed to AIMCO Properties, L.P. was approximately $11,782,000 and $10,775,000, respectively, and is included in due to affiliates. The Partnership may receive additional advances of funds from AIMCO Properties, L.P. although AIMCO Properties, L.P. is not obligated to provide such advances. For more information on AIMCO Properties, L.P., including copies of its audited balance sheet, please see its reports filed with the Securities and Exchange Commission.

Upon the sale of the Partnership’s property, NPI Equity will be entitled to an Incentive Compensation Fee equal to 3% of the difference between the sales price of the property and the appraised value for such property at February 1, 1992. Payment of the Incentive Compensation Fee is subordinated to the receipt by the limited partners, of: (a) distributions from capital transaction proceeds of an amount equal to their appraised investment in the Partnership at February 1, 1992, and (b) distributions from all sources (capital transactions as well as cash flow) of an amount equal to six percent (6%) per annum cumulative, non-compounded, on their appraised investment in the Partnership at February 1, 1992. Prior to 2013, these preferences were met.

The Partnership insures its property up to certain limits through coverage provided by Aimco which is generally self-insured for a portion of losses and liabilities related to workers’ compensation, property casualty, general liability, and vehicle liability. The Partnership insures its property above the Aimco limits through insurance policies obtained by Aimco from insurers unaffiliated with the Managing General Partner. During the years ended December 31, 2014 and 2013, the Partnership was charged by Aimco and its affiliates approximately $64,000 and $60,000, respectively, for insurance coverage and fees associated with policy claims administration.

In addition to its indirect ownership of the Managing General Partner interest in the Partnership, Aimco and its affiliates owned 76,622 Units in the Partnership representing 70.01% of the outstanding Units at December 31, 2014. A number of these Units were acquired pursuant to tender offers made by Aimco or its affiliates. It is possible that Aimco or its affiliates will acquire additional Units in exchange for cash or a combination of cash and units in AIMCO Properties, L.P., the operating partnership of Aimco, either through private purchases or tender offers. Pursuant to the Partnership Agreement, Unit holders holding a majority of the Units are entitled to take action with respect to a variety of matters that include, but are not limited to, voting on certain amendments to the Partnership Agreement and voting to remove the Managing General Partner. As a result of its ownership of 70.01% of the outstanding Units, Aimco and its affiliates are in a position to influence all such voting decisions with respect to the Partnership. However, with respect to the 47,624 Units acquired on January 19, 1996, AIMCO IPLP, L.P. ("IPLP"), an affiliate of the Managing General Partner and of Aimco, agreed to vote such Units: (i) against any increase in compensation payable to the Managing General Partner or to its affiliates; and (ii) on all other matters submitted by it or its affiliates, in proportion to the vote cast by third party unitholders. Except for the foregoing, no other limitations are imposed on IPLP's, Aimco's or any other affiliates' right to vote each Unit held. Although the Managing General Partner owes fiduciary duties to the limited partners of the Partnership, the Managing General Partner also owes fiduciary duties to Aimco as its sole stockholder. As a result, the duties of the Managing General Partner, as Managing General Partner, to the Partnership and its limited partners may come into conflict with the duties of the Managing General Partner to Aimco as its sole stockholder.

Additions charged to expense	1,245			1,574
Retirement of assets	(358		)	(323		)

During the years ended December 31, 2014 and 2013, the Partnership retired and wrote-off property improvements and replacements no longer being used that had a cost basis of approximately $358,000 and $323,000, respectively, and accumulated depreciation of approximately $358,000 and $323,000, respectively, which are included in the table above.

The aggregate cost of the investment property for Federal income tax purposes at December 31, 2014 and 2013 is approximately $38,071,000 and $37,252,000, respectively. The accumulated depreciation taken for Federal income tax purposes at December 31, 2014 and 2013 is approximately $30,498,000 and $28,691,000, respectively.

Note F – Casualty Event

In April 2014, Colony at Kenilworth Apartments sustained damages from a fire which affected three apartment units. The estimated damages are approximately $160,000 and the Partnership expects to receive insurance proceeds. During the year ended December 31, 2014, the Partnership incurred reconstruction costs of approximately $133,000 of which approximately $74,000 were repair and clean-up costs that are included in operating expenses. The Partnership does not expect to record a loss from this event.

Note G – Contingencies

The Partnership is unaware of any pending or outstanding litigation matters involving it or its investment property that are not of a routine nature arising in the ordinary course of business.

Various Federal, state and local laws subject apartment community owners or operators to liability for management, and the costs of removal or remediation, of certain potentially hazardous materials that may be present in the land or buildings of an apartment community. Potentially hazardous materials may include polychlorinated biphenyls, petroleum-based fuels, lead-based paint, or asbestos. Such laws often impose liability without regard to fault or whether the owner or operator knew of, or was responsible for, the presence of such materials. The presence of, or the failure to manage or remediate properly, these materials may adversely affect occupancy at such apartment communities as well as the ability to sell or finance such apartment communities. In addition, governmental agencies may bring claims for costs associated with investigation and remediation actions, damages to natural resources and for potential fines or penalties in connection with such damage or with respect to the improper management of hazardous materials. Moreover, private plaintiffs may potentially make claims for personal injury, disease, disability or other infirmities related to the alleged presence of hazardous materials at an apartment community.

Note H – Subsequent Event

On February 2, 2015, the Partnership entered into a sale contract with a third party relating to the sale of Colony at Kenilworth Apartments. The sale is projected to close on March 31, 2015 with a sales price of $44,200,000. The Partnership has determined that certain held for sale criteria have not been met at December 31, 2014 and therefore continues to report the assets and liabilities of Colony at Kenilworth Apartments as held for investment and its operations as continuing operations.

Item 9. Changes in and Disagreements with Accountants on Accounting and Financial Disclosure

None.

Item 9A. Controls and Procedures

(a) Disclosure Controls and Procedures

The Partnership’s management, with the participation of the principal executive officer and principal financial officer of the Managing General Partner, who are the equivalent of the Partnership’s principal executive officer and principal financial officer, respectively, has evaluated the effectiveness of the Partnership’s disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) as of the end of the period covered by this report. Based on such evaluation, the principal executive officer and principal financial officer of the Managing General Partner, who are the equivalent of the Partnership’s principal executive officer and principal financial officer, respectively, have concluded that, as of the end of such period, the Partnership’s disclosure controls and procedures are effective.

Management’s Report on Internal Control Over Financial Reporting

The Partnership’s management is responsible for establishing and maintaining adequate internal control over financial reporting. Internal control over financial reporting is defined in Rule 13a-15(f) and 15d-15(f) under the Exchange Act as a process designed by, or under the supervision of, the principal executive and principal financial officers of the Managing General Partner, who are the equivalent of the Partnership’s principal executive officer and principal financial officer, respectively, and effected by the Partnership’s management and other personnel to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles and includes those policies and procedures that:

• pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of assets;

• provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures are being made only in accordance with authorizations of the Partnership’s management; and

• provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Projections of any evaluation of effectiveness to future periods are subject to the risks that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

The Partnership’s management assessed the effectiveness of the Partnership’s internal control over financial reporting as of December 31, 2014. In making this assessment, the Partnership’s management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control-Integrated Framework (2013 Framework).

Based on their assessment, the Partnership’s management concluded that, as of December 31, 2014, the Partnership’s internal control over financial reporting is effective.

This annual report does not include an attestation report of the Partnership’s registered public accounting firm regarding internal control over financial reporting. Management’s report was not subject to attestation by the Partnership’s registered public accounting firm pursuant to rules of the Securities and Exchange Commission that permit the Partnership to provide only management’s report in this annual report.

(b) Changes in Internal Control Over Financial Reporting.

There has been no change in the Partnership’s internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during the fourth quarter of 2014 that has materially affected, or is reasonably likely to materially affect, the Partnership’s internal control over financial reporting.

Item 13. Certain Relationships and Related Transactions, and Director Independence

The Partnership has no employees and depends on the Managing General Partner and its affiliates for the management and administration of all Partnership activities. The Partnership Agreement provides for certain payments to affiliates for services and as reimbursement of certain expenses incurred by affiliates on behalf of the Partnership.

Affiliates of the Managing General Partner receive 5% of gross receipts from the Partnership's property as compensation for providing property management services. The Partnership paid to such affiliates approximately $260,000 and $247,000 for the years ended December 31, 2014 and 2013, respectively, which are included in operating expense.

Affiliates of the Managing General Partner charged the Partnership for reimbursement of accountable administrative expenses amounting to approximately $116,000 and $139,000 for the years ended December 31, 2014 and 2013, respectively, which is included in general and administrative expenses and investment property. The portion of these reimbursements included in investment property for the years ended December 31, 2014 and 2013 are construction management services provided by an affiliate of the Managing General Partner of approximately $80,000 and $103,000, respectively. At December 31, 2013, approximately $163,000 of reimbursements were due to the Managing General Partner and are included in due to affiliates.

For services relating to the administration of the Partnership and operation of the Partnership's property, the Managing General Partner is entitled to receive payment for non-accountable expenses up to a maximum of $150,000 per year based upon the number of Partnership units sold, subject to certain limitations. No such reimbursements were made during the years ended December 31, 2014 or 2013.

As compensation for services rendered in managing the Partnership, the Managing General Partner is entitled to receive Partnership management fees in conjunction with distributions of cash from operations, subject to certain limitations. No such Partnership management fees were earned or paid during the years ended December 31, 2014 or 2013.

The Partnership may receive advances of funds from AIMCO Properties, L.P., an affiliate of the Managing General Partner and the holder of a majority of the beneficial interest of the Partnership. During the years ended December 31, 2014 and 2013, AIMCO Properties, L.P. advanced the Partnership approximately $550,000 and $525,000, respectively, to fund real estate taxes at the Partnership’s investment property. The advances bear interest at the prime rate plus 2% (5.25% at December 31, 2014) per annum. Interest expense was approximately $587,000 and $534,000 for the years ended December 31, 2014 and 2013, respectively. During the year ended December 31, 2014, the Partnership paid $130,000 of accrued interest. At December 31, 2014 and 2013, the total advances and accrued interest owed to AIMCO Properties, L.P. was approximately $11,782,000 and $10,775,000, respectively, and is included in due to affiliates. The Partnership may receive additional advances of funds from AIMCO Properties, L.P. although AIMCO Properties, L.P. is not obligated to provide such advances. For more information on

AIMCO Properties, L.P., including copies of its audited balance sheet, please see its reports filed with the Securities and Exchange Commission.

Upon the sale of the Partnership’s property, NPI Equity will be entitled to an Incentive Compensation Fee equal to 3% of the difference between the sales price of the property and the appraised value for such property at February 1, 1992. Payment of the Incentive Compensation Fee is subordinated to the receipt by the limited partners, of: (a) distributions from capital transaction proceeds of an amount equal to their appraised investment in the Partnership at February 1, 1992, and (b) distributions from all sources (capital transactions as well as cash flow) of an amount equal to six percent (6%) per annum cumulative, non-compounded, on their appraised investment in the Partnership at February 1, 1992. Prior to 2013, these preferences were met.

The Partnership insures its property up to certain limits through coverage provided by Aimco which is generally self-insured for a portion of losses and liabilities related to workers’ compensation, property casualty, general liability and vehicle liability. The Partnership insures its property above the Aimco limits through insurance policies obtained by Aimco from insurers unaffiliated with the Managing General Partner. During the years ended December 31, 2014 and 2013, the Partnership was charged by Aimco and its affiliates approximately $64,000 and $60,000, respectively, for insurance coverage and fees associated with policy claims administration.

In addition to its indirect ownership of the Managing General Partner interest in the Partnership, Aimco and its affiliates owned 76,622 Units in the Partnership representing 70.01% of the outstanding Units at December 31, 2014. A number of these Units were acquired pursuant to tender offers made by Aimco or its affiliates. It is possible that Aimco or its affiliates will acquire additional Units in exchange for cash or a combination of cash and units in AIMCO Properties, L.P., the operating partnership of Aimco, either through private purchases or tender offers. Pursuant to the Partnership Agreement, Unit holders holding a majority of the Units are entitled to take action with respect to a variety of matters that include, but are not limited to, voting on certain amendments to the Partnership Agreement and voting to remove the Managing General Partner. As a result of its ownership of 70.01% of the outstanding Units, Aimco and its affiliates are in a position to influence all such voting decisions with respect to the Partnership. However, with respect to the 47,624 Units acquired on January 19, 1996, AIMCO IPLP, L.P. ("IPLP"), an affiliate of the Managing General Partner and of Aimco, agreed to vote such Units: (i) against any increase in compensation payable to the Managing General Partner or to its affiliates; and (ii) on all other matters submitted by it or its affiliates, in proportion to the vote cast by third party unitholders.Except for the foregoing, no other limitations are imposed on IPLP's, Aimco's or any other affiliates' right to vote each Unit held. Although the Managing General Partner owes fiduciary duties to the limited partners of the Partnership, the Managing General Partner also owes fiduciary duties to Aimco as its sole stockholder. As a result, the duties of the Managing General Partner, as Managing General Partner, to the Partnership and its limited partners may come into conflict with the duties of the Managing General Partner to Aimco as its sole stockholder.

Neither of the Managing General Partner's directors is independent under the independence standards established for New York Stock Exchange listed companies as both directors are employed by the parent of the Managing General Partner.

Item 14. Principal Accounting Fees and Services

Tax Fees. Fees for tax services totaled approximately $6,000 for both 2014 and 2013.

As a result of its ownership of 70.01% of the outstanding Units, Aimco and its affiliates are in a position to influence all such voting decisions with respect to the Partnership. However, with respect to the 47,624 Units acquired on January 19, 1996, AIMCO IPLP, L.P. ("IPLP"), an affiliate of the Managing General Partner and of Aimco, agreed to vote such Units: (i) against any increase in compensation payable to the Managing General Partner or to its affiliates; and (ii) on all other matters submitted by it or its affiliates, in proportion to the vote cast by third party unitholders. Except for the foregoing, no other limitations are imposed on IPLP's, Aimco's or any other affiliates' right to vote each Unit held. Although the Managing General Partner owes fiduciary duties to the limited partners of the Partnership, the Managing General Partner also owes fiduciary duties to Aimco as its sole stockholder. As a result, the duties of the Managing General Partner, as Managing General Partner, to the Partnership and its limited partners may come into conflict with the duties of the Managing General Partner to Aimco as its sole stockholder.

Organization and Summary of Significant Accounting Policies (Notes)

Dec. 31, 2014

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Basis of Presentation

Note A – Organization and Summary of Significant Accounting Policies

Organization

National Property Investors 6 (the "Partnership" or "Registrant") is a California limited partnership formed on October 15, 1982. The Partnership is engaged in the business of operating and holding one apartment property located in Towson, Maryland for investment. NPI Equity Investments, Inc., a Florida corporation, became the Partnership's managing general partner (the "Managing General Partner" or "NPI Equity") on June 21, 1991. The Managing General Partner is a subsidiary of Apartment Investment and Management Company ("Aimco"), a publicly traded real estate investment trust. The partnership agreement provides that the Partnership is to terminate on December 31, 2022.

Subsequent Events

The Partnership’s management evaluated subsequent events through the time this Annual Report on Form 10-K was filed.

Reclassifications

Certain reclassifications have been made to the 2013 balances to conform to the 2014 presentation.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates.

Abandoned Units

During the years ended December 31, 2014 and 2013, the number of limited partnership units (the “Units”) decreased by 50 and 28 Units, respectively, due to limited partners abandoning their Units. In abandoning his or her Units, a limited partner relinquishes all right, title and interest in the Partnership as of the date of the abandonment.

Net Loss Per Limited Partnership Unit

At December 31, 2014 and 2013, the Partnership had outstanding 109,446 and 109,496 Units, respectively. Net loss per Limited Partnership Unit is computed by dividing net loss allocated to the limited partners by the number of Units outstanding at the beginning of the fiscal year. The number of Units used was 109,496 and 109,524 Units for the years ended December 31, 2014 and 2013, respectively.

Allocation of Income, Loss and Distributions

Net income, net loss and distributions of cash of the Partnership are allocated between the general and limited partners in accordance with the provisions of the Partnership Agreement.

Note A – Organization and Summary of Significant Accounting Policies (continued)

Fair Value of Financial Statements

Financial Accounting Standards Board Accounting Standards Codification Topic 825, “Financial Instruments”, requires disclosure of fair value information about financial instruments, whether or not recognized in the balance sheet, for which it is practicable to estimate fair value. Fair value is defined as the amount at which the instruments could be exchanged in a current transaction between willing parties, other than in a forced or liquidation sale. The Partnership is required to classify these fair value measurements into one of three categories, based on the nature of the inputs used in the fair value measurement. Level 1 of the hierarchy includes fair value measurements based on unadjusted quoted prices in active markets for identical assets or liabilities the Partnership can access at the measurement date. Level 2 includes fair value measurements based on inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly. Level 3 includes fair value measurements based on unobservable inputs. The classification of fair value measurements is subjective and generally accepted accounting principles requires the Partnership to disclose more detailed information regarding those fair value measurements classified within the lower levels of the hierarchy. The Partnership believes that the carrying amount of its financial instruments (except for mortgage notes payable) approximates their fair value due to the short-term maturity of these instruments. The Partnership estimates the fair value of its mortgage notes payable by discounting future cash flows using a discount rate commensurate with that currently believed to be available to the Partnership for similar term, mortgage notes payable. The Partnership has classified this fair value measurement within Level 2 of the fair value hierarchy. At December 31, 2014, the fair value of the Partnership's mortgage notes payable at the Partnership's incremental borrowing rate was approximately $25,657,000.

Cash and Cash Equivalents

Cash and cash equivalents include cash on hand and cash in banks. At certain times, the amount of cash deposited at a bank may exceed the limit on insured deposits. Cash balances included approximately $215,000 and $261,000 at December 31, 2014 and 2013, respectively, that are maintained by an affiliated management company on behalf of affiliated entities in cash concentration accounts.

Tenant Security Deposits

The Partnership requires security deposits from lessees for the duration of the lease and such deposits are included in receivables and deposits. The security deposits are refunded when the tenant vacates, provided the tenant has not damaged the space and is current on rental payments.

Depreciation

Depreciation is provided by the straight-line method over the estimated lives of the apartment property and related personal property. For Federal income tax purposes, the modified accelerated cost recovery method is used for depreciation of

(1) real property over 27.5 years and (2) personal property additions over 5 years.

Deferred Costs

Loan costs of approximately $649,000 at both December 31, 2014 and 2013, less accumulated amortization of approximately $427,000 and $388,000, respectively, are included in other assets and are amortized over the term of the related loan agreements. The total amortization expense for each of the years ended December 31, 2014 and 2013 was approximately $39,000 and is included in interest expense. Amortization expense is expected to be approximately $39,000 for each of the years 2015 through 2018 and approximately $31,000 for 2019.

Leasing commissions and other direct costs incurred in connection with successful leasing efforts are deferred and amortized over the terms of the related leases. Amortization of these costs is included in operating expenses.

Note A – Organization and Summary of Significant Accounting Policies (continued)

Leases

The Partnership generally leases apartment units for twelve-month terms or less. The Partnership will offer rental concessions during particularly slow months or in response to heavy competition from other similar complexes in the area. Rental income attributable to leases, net of any concessions, is recognized on a straight-line basis over the term of the lease. The Partnership evaluates all accounts receivable from residents and establishes an allowance, after the application of security deposits, for accounts greater than 30 days past due on current residents and all receivables due from former residents.

Investment Property

Investment property consists of one apartment complex and is stated at cost, less accumulated depreciation, unless the carrying amount of the asset is not recoverable. The Partnership capitalizes costs incurred in connection with capital additions activities, including redevelopment and construction projects, other tangible property improvements and replacements of existing property components. Included in these capitalized costs are payroll costs associated with time spent by site employees in connection with capital additions activities at the property level. The Partnership capitalizes interest, property taxes and insurance during periods in which redevelopment and construction projects are in progress. The Partnership did not capitalize any costs related to interest, property taxes or insurance during the years ended December 31, 2014 and 2013. Capitalized costs are depreciated over the estimated useful life of the asset. The Partnership charges to expense as incurred costs including ordinary repairs, maintenance and resident turnover costs.

If events or circumstances indicate that the carrying amount of the property may not be recoverable, the Partnership will make an assessment of its recoverability by comparing the carrying amount to the Partnership’s estimate of the undiscounted future cash flows, excluding interest charges, of the property. If the carrying amount exceeds the estimated aggregate undiscounted future cash flows, the Partnership would recognize an impairment loss to the extent the carrying amount exceeds the estimated fair value of the property. No adjustments for impairment of value were necessary for the years ending December 31, 2014 and 2013.

Segment Reporting

ASC Topic 280-10, “Segment Reporting”, established standards for the way that public business enterprises report information about operating segments in annual financial statements and requires that those enterprises report selected information about operating segments in interim financial reports. ASC Topic 280-10 also established standards for related disclosures about products and services, geographic areas, and major customers. As defined in ASC Topic 280-10, the Partnership has only one reportable segment.

Advertising Costs

Advertising costs of approximately $85,000 for the years ended December 31, 2014 and 2013, respectively, were charged to expense as incurred and are included in operating expenses.

Recent Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board (“FASB”) and the International Accounting Standards Board issued their final standard on revenue from contracts with customers which was issued by the FASB as Accounting Standards Update 2014-09, Revenue from Contracts with Customers, or ASU 2014-09.  ASU 2014-09, which establishes a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers, supersedes most current generally accepted accounting principles applicable to revenue recognition and converges U.S. and international accounting standards in this area. The core principle of the new guidance is that revenue shall only be recognized when an entity has transferred control of goods or services to a customer and for an amount reflecting the consideration to which the entity expects to be entitled for such exchange.

ASU 2014-09 is effective for public entities for annual reporting periods beginning after December 15, 2016, with no early adoption permitted, and allows for full retrospective adoption applied to all periods presented or modified retrospective adoption with the cumulative effect of initially applying the standard recognized at the date of initial application.  The Partnership has not yet determined the effect ASU 2014-09 will have on its financial statements.

Note A – Organization and Summary of Significant Accounting Policies(continued)

In August 2014, The FASB issued Accounting Standards Update 2014-15, Presentation of Financial Statements-Going Concern, or ASU 2014-15. ASU 2014-15 requires management to evaluate whether there are conditions and events, considered in the aggregate, that raise substantial doubt about the entity’s ability to continue as a going concern within one year after the date that the financial statements are issued.

This evaluation should include consideration of whether it is probable that the entity will be unable to meet its obligations as they become due within one year after the date that the financial statements are issued, and should initially take into consideration the potential mitigating effect of management’s plans that have not been fully implemented as of the date that the financial statements are issued (e.g. plans to raise capital, borrow money, restructure debt, etc). Entities must disclose the principal conditions or events that raise substantial doubt about the entity’s ability to continue as a going concern, as well as management’s evaluation of those conditions and potential plans for mitigation.

ASU 2014-15 is effective for all entities for annual reporting periods ending after December 15, 2016, and interim periods thereafter, with early adoption permitted. The Partnership does not expect ASU 2014-15 to have a material effect on its financial statements.

Contingencies

Note G – Contingencies

The Partnership is unaware of any pending or outstanding litigation matters involving it or its investment property that are not of a routine nature arising in the ordinary course of business.

Various Federal, state and local laws subject apartment community owners or operators to liability for management, and the costs of removal or remediation, of certain potentially hazardous materials that may be present in the land or buildings of an apartment community. Potentially hazardous materials may include polychlorinated biphenyls, petroleum-based fuels, lead-based paint, or asbestos. Such laws often impose liability without regard to fault or whether the owner or operator knew of, or was responsible for, the presence of such materials. The presence of, or the failure to manage or remediate properly, these materials may adversely affect occupancy at such apartment communities as well as the ability to sell or finance such apartment communities. In addition, governmental agencies may bring claims for costs associated with investigation and remediation actions, damages to natural resources and for potential fines or penalties in connection with such damage or with respect to the improper management of hazardous materials. Moreover, private plaintiffs may potentially make claims for personal injury, disease, disability or other infirmities related to the alleged presence of hazardous materials at an apartment community.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Business Description and Basis of Presentation [Text Block]

Organization

National Property Investors 6 (the "Partnership" or "Registrant") is a California limited partnership formed on October 15, 1982. The Partnership is engaged in the business of operating and holding one apartment property located in Towson, Maryland for investment. NPI Equity Investments, Inc., a Florida corporation, became the Partnership's managing general partner (the "Managing General Partner" or "NPI Equity") on June 21, 1991. The Managing General Partner is a subsidiary of Apartment Investment and Management Company ("Aimco"), a publicly traded real estate investment trust. The partnership agreement provides that the Partnership is to terminate on December 31, 2022.

Subsequent Events, Policy [Policy Text Block]

Subsequent Events

The Partnership’s management evaluated subsequent events through the time this Annual Report on Form 10-K was filed.

Reclassification, Policy [Policy Text Block]

Reclassifications

Certain reclassifications have been made to the 2013 balances to conform to the 2014 presentation.

Use of Estimates, Policy [Policy Text Block]

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates.

Abandoned Units [Policy Text Block]

Abandoned Units

During the years ended December 31, 2014 and 2013, the number of limited partnership units (the “Units”) decreased by 50 and 28 Units, respectively, due to limited partners abandoning their Units. In abandoning his or her Units, a limited partner relinquishes all right, title and interest in the Partnership as of the date of the abandonment.

Allocation Of Income Loss And Distributions [Policy Text Block]

Allocation of Income, Loss and Distributions

Net income, net loss and distributions of cash of the Partnership are allocated between the general and limited partners in accordance with the provisions of the Partnership Agreement.

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

Fair Value of Financial Statements

Financial Accounting Standards Board Accounting Standards Codification Topic 825, “Financial Instruments”, requires disclosure of fair value information about financial instruments, whether or not recognized in the balance sheet, for which it is practicable to estimate fair value. Fair value is defined as the amount at which the instruments could be exchanged in a current transaction between willing parties, other than in a forced or liquidation sale. The Partnership is required to classify these fair value measurements into one of three categories, based on the nature of the inputs used in the fair value measurement. Level 1 of the hierarchy includes fair value measurements based on unadjusted quoted prices in active markets for identical assets or liabilities the Partnership can access at the measurement date. Level 2 includes fair value measurements based on inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly. Level 3 includes fair value measurements based on unobservable inputs. The classification of fair value measurements is subjective and generally accepted accounting principles requires the Partnership to disclose more detailed information regarding those fair value measurements classified within the lower levels of the hierarchy. The Partnership believes that the carrying amount of its financial instruments (except for mortgage notes payable) approximates their fair value due to the short-term maturity of these instruments. The Partnership estimates the fair value of its mortgage notes payable by discounting future cash flows using a discount rate commensurate with that currently believed to be available to the Partnership for similar term, mortgage notes payable. The Partnership has classified this fair value measurement within Level 2 of the fair value hierarchy. At December 31, 2014, the fair value of the Partnership's mortgage notes payable at the Partnership's incremental borrowing rate was approximately $25,657,000.

Cash and Cash Equivalents, Policy [Policy Text Block]

Cash and Cash Equivalents

Cash and cash equivalents include cash on hand and cash in banks. At certain times, the amount of cash deposited at a bank may exceed the limit on insured deposits. Cash balances included approximately $215,000 and $261,000 at December 31, 2014 and 2013, respectively, that are maintained by an affiliated management company on behalf of affiliated entities in cash concentration accounts.

Tenant Security Deposits [Policy Text Block]

Tenant Security Deposits

The Partnership requires security deposits from lessees for the duration of the lease and such deposits are included in receivables and deposits. The security deposits are refunded when the tenant vacates, provided the tenant has not damaged the space and is current on rental payments.

Depreciation, Depletion, and Amortization [Policy Text Block]

Depreciation

Depreciation is provided by the straight-line method over the estimated lives of the apartment property and related personal property. For Federal income tax purposes, the modified accelerated cost recovery method is used for depreciation of

(1) real property over 27.5 years and (2) personal property additions over 5 years.

Deferred Charges, Policy [Policy Text Block]

Deferred Costs

Loan costs of approximately $649,000 at both December 31, 2014 and 2013, less accumulated amortization of approximately $427,000 and $388,000, respectively, are included in other assets and are amortized over the term of the related loan agreements. The total amortization expense for each of the years ended December 31, 2014 and 2013 was approximately $39,000 and is included in interest expense. Amortization expense is expected to be approximately $39,000 for each of the years 2015 through 2018 and approximately $31,000 for 2019.

Leasing commissions and other direct costs incurred in connection with successful leasing efforts are deferred and amortized over the terms of the related leases. Amortization of these costs is included in operating expenses.

Lease, Policy [Policy Text Block]

Leases

The Partnership generally leases apartment units for twelve-month terms or less. The Partnership will offer rental concessions during particularly slow months or in response to heavy competition from other similar complexes in the area. Rental income attributable to leases, net of any concessions, is recognized on a straight-line basis over the term of the lease. The Partnership evaluates all accounts receivable from residents and establishes an allowance, after the application of security deposits, for accounts greater than 30 days past due on current residents and all receivables due from former residents.

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

Investment Property

Investment property consists of one apartment complex and is stated at cost, less accumulated depreciation, unless the carrying amount of the asset is not recoverable. The Partnership capitalizes costs incurred in connection with capital additions activities, including redevelopment and construction projects, other tangible property improvements and replacements of existing property components. Included in these capitalized costs are payroll costs associated with time spent by site employees in connection with capital additions activities at the property level. The Partnership capitalizes interest, property taxes and insurance during periods in which redevelopment and construction projects are in progress. The Partnership did not capitalize any costs related to interest, property taxes or insurance during the years ended December 31, 2014 and 2013. Capitalized costs are depreciated over the estimated useful life of the asset. The Partnership charges to expense as incurred costs including ordinary repairs, maintenance and resident turnover costs.

If events or circumstances indicate that the carrying amount of the property may not be recoverable, the Partnership will make an assessment of its recoverability by comparing the carrying amount to the Partnership’s estimate of the undiscounted future cash flows, excluding interest charges, of the property. If the carrying amount exceeds the estimated aggregate undiscounted future cash flows, the Partnership would recognize an impairment loss to the extent the carrying amount exceeds the estimated fair value of the property. No adjustments for impairment of value were necessary for the years ending December 31, 2014 and 2013.

Segment Reporting, Policy [Policy Text Block]

Segment Reporting

ASC Topic 280-10, “Segment Reporting”, established standards for the way that public business enterprises report information about operating segments in annual financial statements and requires that those enterprises report selected information about operating segments in interim financial reports. ASC Topic 280-10 also established standards for related disclosures about products and services, geographic areas, and major customers. As defined in ASC Topic 280-10, the Partnership has only one reportable segment.

Advertising Costs, Policy [Policy Text Block]

Advertising Costs

Advertising costs of approximately $85,000 for the years ended December 31, 2014 and 2013, respectively, were charged to expense as incurred and are included in operating expenses.

New Accounting Pronouncements, Policy [Policy Text Block]

Recent Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board (“FASB”) and the International Accounting Standards Board issued their final standard on revenue from contracts with customers which was issued by the FASB as Accounting Standards Update 2014-09, Revenue from Contracts with Customers, or ASU 2014-09.  ASU 2014-09, which establishes a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers, supersedes most current generally accepted accounting principles applicable to revenue recognition and converges U.S. and international accounting standards in this area. The core principle of the new guidance is that revenue shall only be recognized when an entity has transferred control of goods or services to a customer and for an amount reflecting the consideration to which the entity expects to be entitled for such exchange.

ASU 2014-09 is effective for public entities for annual reporting periods beginning after December 15, 2016, with no early adoption permitted, and allows for full retrospective adoption applied to all periods presented or modified retrospective adoption with the cumulative effect of initially applying the standard recognized at the date of initial application.  The Partnership has not yet determined the effect ASU 2014-09 will have on its financial statements.

Note A – Organization and Summary of Significant Accounting Policies(continued)

In August 2014, The FASB issued Accounting Standards Update 2014-15, Presentation of Financial Statements-Going Concern, or ASU 2014-15. ASU 2014-15 requires management to evaluate whether there are conditions and events, considered in the aggregate, that raise substantial doubt about the entity’s ability to continue as a going concern within one year after the date that the financial statements are issued.

This evaluation should include consideration of whether it is probable that the entity will be unable to meet its obligations as they become due within one year after the date that the financial statements are issued, and should initially take into consideration the potential mitigating effect of management’s plans that have not been fully implemented as of the date that the financial statements are issued (e.g. plans to raise capital, borrow money, restructure debt, etc). Entities must disclose the principal conditions or events that raise substantial doubt about the entity’s ability to continue as a going concern, as well as management’s evaluation of those conditions and potential plans for mitigation.

ASU 2014-15 is effective for all entities for annual reporting periods ending after December 15, 2016, and interim periods thereafter, with early adoption permitted. The Partnership does not expect ASU 2014-15 to have a material effect on its financial statements.
