NOTES TO CONDENSED FINANCIAL STATEMENTS

FOR THE THREE AND SIX MONTHS ENDED JUNE 30, 2007

UNAUDITED

NOTE 1 — BASIS OF PRESENTATION

The accompanying unaudited condensed financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by accounting principles generally accepted in the United States of America for complete financial statements and should therefore be read in conjunction with the financial statements and notes thereto contained in the annual report on Form 10-K for the year ended December 31, 2006 for Del Taco Income Properties IV (the Partnership or the Company). In the opinion of management, all adjustments (consisting of normal recurring accruals) necessary to present fairly the Partnership’s financial position at June 30, 2007, the results of operations for the three and six month periods ended June 30, 2007 and 2006 and cash flows for the six month periods ended June 30, 2007 and 2006 have been included. Operating results for the three and six months ended June 30, 2007 are not necessarily indicative of the results that may be expected for the year ending December 31, 2007.

NOTE 2 — NET INCOME PER LIMITED PARTNERSHIP UNIT

Net income per limited partnership unit is based on net income attributable to the limited partners (after 1% allocation to the general partner) using the weighted average number of units outstanding during the periods presented which amounted to 165,375 in 2007 and 2006.

Pursuant to the partnership agreement, annual partnership income or loss is allocated one percent to Del Taco LLC, formerly known as Del Taco Inc., (Del Taco or the General Partner) and 99 percent to the limited partners. Partnership gains from any sale or refinancing will be allocated one percent to the General Partner and 99 percent to the limited partners until allocated gains and profits equal losses, distributions and syndication costs, and until each class of limited partners receive their priority return as defined in the partnership agreement. Additional gains will be allocated 12 percent to the General Partner and 88 percent to the limited partners.

NOTE 3 — LEASING ACTIVITIES

The Partnership leases certain properties for operation of restaurants to Del Taco on a triple net basis. The leases are for terms of 32 years commencing with the completion of the restaurant facility located on each property and require monthly rentals equal to 12 percent of the gross sales of the restaurants. The leases terminate in the years 2023 to 2024. There is no minimum rental under any of the leases.

NOTES TO CONDENSED FINANCIAL STATEMENTS — CONTINUED

FOR THE THREE AND SIX MONTHS ENDED JUNE 30, 2007

UNAUDITED

NOTE 3 — LEASING ACTIVITIES — continued

For the three months ended June 30, 2006, the two restaurants operated by Del Taco, for which the Partnership is the lessor, had combined, unaudited sales of $576,328 and unaudited net income of $15,505 as compared to $570,571 and $28,056, respectively, for the corresponding period in 2006. Net income or loss of each restaurant includes charges for general and administrative expenses incurred in connection with supervision of restaurant operations and interest expense. For the three months ended June 30, 2007, the one restaurant operated by a Del Taco franchisee, for which the Partnership is the lessor, had unaudited sales of $339,887 as compared with $393,771 during the same period in 2006.

For the six months ended June 30, 2007, the two restaurants operated by Del Taco, for which the Partnership is the lessor, had combined, unaudited sales of $1,127,412 and unaudited net income of $34,452 as compared to $1,121,248 and $75,648, respectively, for the corresponding period in 2006. Net income or loss of each restaurant includes charges for general and administrative expenses incurred in connection with supervision of restaurant operations and interest expense and the decrease in net income from the corresponding period of the prior year primarily relates to additional interest expense from the debt that was issued in connection with the acquisition of Del Taco (see Note 8). For the six months ended June 30, 2007, the one restaurant operated by a Del Taco franchisee, for which the Partnership is the lessor, had unaudited sales of $660,355 as compared with $759,802 during the same period in 2006.

NOTE 4 — TRANSACTIONS WITH DEL TACO

The receivable from Del Taco consists primarily of rent accrued for the month of June 2007. The June rent was collected in July 2007.

Del Taco serves in the capacity of general partner in other partnerships which are engaged in the business of operating restaurants, and three other partnerships which were formed for the purpose of acquiring real property in California for construction of Mexican-American restaurants for lease under long-term agreements to Del Taco for operation under the Del Taco trade name.

In addition, see Note 5 with respect to certain distributions to the General Partner.

NOTE 5 — DISTRIBUTIONS

Total cash distributions declared and paid in January and April 2007 were $104,512 and $88,611, respectively. On July 23, 2007, a distribution to the limited partners of $75,486, or approximately $0.46 per limited partnership unit, was declared. Such distribution was paid July 30, 2007. The General Partner also received a distribution of $762 with respect to its 1% partnership interest.

FOR THE THREE AND SIX MONTHS ENDED JUNE 30, 2007

UNAUDITED

NOTE 6 — PAYABLE TO LIMITED PARTNERS

Payable to limited partners represents a reclassification from cash for distribution checks made to limited partners that have remained outstanding for six months or longer.

NOTE 7 — CONCENTRATION OF RISK

The three restaurants leased to Del Taco make up all of the income producing assets of the Partnership and contributed all of the Partnership’s rental revenues during the three and six months ended June 30, 2007 and 2006. Therefore, the business of the Partnership is entirely dependent on the success of the Del Taco trade name restaurants that lease the properties.

NOTE 8 — ACQUISITION OF GENERAL PARTNER

On January 30, 2006, the parent company of the General Partner entered into an agreement to sell all of its issued and outstanding common stock to Sagittarius Acquisitions II, Inc. The transaction was consummated on March 29, 2006 and did not have an impact on the financial position, results of operations or cash flows of the Partnership.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

Liquidity and Capital Resources

Del Taco Income Properties IV (the Partnership or the Company) offered limited partnership units for sale between June 1987 and June 1988. $4.135 million was raised through the sale of limited partnership units and used to acquire sites and build three restaurants and also to pay commissions to brokers and to reimburse Del Taco LLC (Del Taco or the General Partner) for offering costs incurred. In February of 1992, approximately $442,000 raised during the offering but not required to acquire sites and build restaurants was distributed to the limited partners.

The three restaurants leased to Del Taco make up all of the income producing assets of the Partnership. Therefore, the business of the Partnership is entirely dependent on the success of the Del Taco trade name restaurants that lease the properties. The success of the restaurants is dependent on a large variety of factors, including, but not limited to, competition, consumer demand and preference for fast food, in general, and for Mexican-American food in particular.

Results of Operations

The Partnership owns three properties that are under long-term lease to Del Taco for restaurant operations (Del Taco, in turn, has sub-leased one of the restaurants to a Del Taco franchisee).

The following table sets forth rental revenue earned by restaurant for the three and six months ended June 30, 2007 and 2006 (unaudited):

	Three Months Ended				Six Months Ended
	June 30,				June 30,
	2007		2006		2007		2006
Orangethorpe Ave., Placentia, CA	$	46,390	$	45,099	$	90,121	$	88,287
Lakeshore Drive, Lake Elsinore, CA		40,787		47,253		79,243		91,176
Highland Ave., San Bernardino, CA		22,769		23,369		45,168		46,263
Total	$	109,946	$	115,721	$	214,532	$	225,726

The Partnership receives rental revenues equal to 12 percent of gross sales from the restaurants. The Partnership earned rental revenue of $109,946 during the three month period ended June 30, 2007, which represents a decrease of $5,775 from the corresponding period in 2006. The Partnership earned rental revenue of $214,532 during the six month period ended June 30, 2007, which represents a decrease of $11,194 from the corresponding period in 2006. The changes in rental revenue between 2007 and 2006 are directly attributable to changes in sales levels at the restaurants under lease due to local competitive and industry factors.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations — continued

The following table breaks down general and administrative expenses by type of expense:

	Percent of Total
	General & Administrative Expense
	Three Months Ended						Six Months Ended
	June 30,						June 30,
	2007			2006			2007			2006
Accounting fees		66.36	%		61.04	%		81.94	%		77.69	%
Distribution of information to limited partners		33.64	%		38.96	%		18.06	%		22.31	%
		100.00	%		100.00	%		100.00	%		100.00	%

General and administrative costs for the three month and six month periods ended June 30, 2007 were essentially the same as the corresponding periods in 2006.

For the three month period ended June 30, 2007, net income decreased by $5,824 from 2006 to 2007 due to the decrease in revenues of $5,775, the decrease in interest and other income of $53, partially offset by the decrease in general and administrative expenses of $4. For the six month period ended June 30, 2007, net income decreased by $11,763 from 2006 to 2007 due to a decrease in revenues of $11,194, the decrease in interest and other income of $205, and the increase in general and administrative expenses of $364.

Critical Accounting Policies and Estimates

Management’s discussion and analysis of financial condition and results of operations, as well as disclosures included elsewhere in this report on Form 10-Q are based upon the Partnership’s financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States of America. The preparation of these financial statements requires management to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses. The Partnership believes the critical accounting policies that most impact the financial statements are described below. A summary of the significant accounting policies of the Partnership can be found in Note 1 to the Financial Statements which is included in the Partnership’s December 31, 2006 Form 10-K.

Property and Equipment: Property and equipment is stated at cost. Depreciation is computed using the straight-line method over estimated useful lives which are 20 years for land improvements, 35 years for buildings and improvements, and 10 years for machinery and equipment.

The partnership accounts for property and equipment in accordance with Statement of Financial Accounting Standards (SFAS) No. 144, “Accounting for the Impairment or Disposal of Long Lived Assets.” SFAS 144 requires that long-lived assets be reviewed for impairment whenever events or changes in circumstances indicate that the carrying value of the asset may not be recoverable. In evaluating long-lived assets held for use, an impairment loss is recognized if the sum of the expected future cash flows (undiscounted and without interest charges) is less than the carrying value of the asset. Once a determination has been made that an impairment loss should be recognized for long-lived assets, various assumptions and estimates are used to determine fair value including, among others, estimated costs of construction and development, recent sales of comparable properties and the opinions of fair value prepared by independent real estate appraisers. Long-lived assets to be disposed of are reported at the lower of carrying amount or fair value less cost to sell.

Item 3. Quantitative and Qualitative Disclosures About Market Risk.

None.

-11-

Item 4. Controls and Procedures

(a) Evaluation of disclosure controls and procedures:

As of the end of the period covered by this quarterly report, we carried out an evaluation, under the supervision and with the participation of the Company’s management, including the Company’s President and Treasurer, of the effectiveness of the design and operation of the Company’s disclosure controls and procedures. Based upon that evaluation, the President and Treasurer concluded that the Company’s disclosure controls and procedures are effective in timely alerting them to material information relating to the Company required to be included in the Company’s periodic Securities and Exchange Commission filings.

(b) Changes in internal controls:

There were no significant changes in the Company’s internal controls over financial reporting that occurred during our most recent fiscal quarter that materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

(c) Asset-Backed issuers:

Not applicable.
