Apartment Investment and Management Company
Announces First Quarter 2010 Results

Denver, Colorado – April 30, 2010 – Apartment Investment and Management Company (NYSE: AIV) announced today its first quarter 2010 results.

Chairman and Chief Executive Officer Terry Considine comments: “Aimco has a simple business plan to own and operate B/B+ quality apartments in the 20 largest U.S. markets. During the first quarter, we increased average daily occupancy to 96.0% in part because a record high percent of our customers chose to renew their leases and stay with us. And, while rental rates on new leases were down from the prior year, rental rates on renewals were up, starting in February and ending seven months of decline. In addition, we sold twelve properties and reduced our corporate term debt by $45 million in the quarter, and by an additional $10 million after quarter’s end. As we move forward in the year, we will continue to focus on providing excellent service to our customers, controlling costs, upgrading our portfolio and strengthening our balance sheet.”

Chief Financial Officer Ernie Freedman adds: “First quarter Pro forma FFO of $0.32 per share exceeded the high end of our guidance range by $0.02 per share, driven mainly by timing of offsite costs. Our guidance for full year 2010 is unchanged at $1.25 to $1.35 per share and we are establishing second quarter Pro forma FFO guidance of $0.28 to $0.34 per share.”

Earnings (loss) per share	$	(0.35	)	$	(0.34	)
Funds From Operations (FFO)	$	0.25		$	0.45

Pro forma Funds from Operations (Pro forma FFO)	$	0.32		$	0.42
Deduct Aimco’s share of capital replacements	$	(0.10	)	$	(0.08	)
Adjusted Funds From Operations (AFFO)	$	0.22		$	0.30

Net income (loss) – Net loss attributable to Aimco common stockholders for the quarter was $40.4 million, compared to net loss of $37.7 million for first quarter 2009. First quarter 2010 net loss was greater than first quarter 2009 primarily due to higher depreciation and amortization as assets under construction were brought into service over the past twelve months.

Funds From Operations – FFO is a non-GAAP financial measure defined in the glossary in Aimco’s Supplemental Information (the Glossary). FFO calculated in accordance with the definition prescribed by the National Association of Real Estate Investment Trusts (NAREIT) was $29.3 million, or $0.25 per share, compared with $51.3 million, or $0.45 per share, in first quarter 2009. Pro forma FFO, which represents FFO as prescribed by NAREIT but excludes operating real estate impairment losses and recoveries, was $36.9 million, or $0.32 per share, compared with $48.8 million, or $0.42 per share, in first quarter 2009. Lower results were primarily due to dilution from 2009 asset sales.

Property Operations

Property operating results discussed below represent Aimco’s Proportionate Share of reported amounts, which reflects property operating results adjusted for Aimco’s ownership in each property. This non-GAAP measure is defined in the Glossary.

Diversified Operating Portfolio – Aimco’s property operations consist primarily of Conventional with some Affordable real estate operations. Conventional real estate operations relate to Aimco’s diversified portfolio of market rate apartment communities and include Same Store Properties, Redevelopment Properties, Acquisition Properties, and Other Properties. See Supplemental Schedules 7a and 7b for detailed information on Aimco’s Conventional real estate portfolio, including selected operating results.

Affordable real estate operations relate to Aimco’s portfolio of properties with rents that are generally paid, in whole or part, by a government agency. Affordable properties tend to have relatively more stable rents and higher occupancy due to government rent payments and thus are much less affected by market fluctuations. See the Glossary for additional information about the property categories included in the table below and Schedules 1 and 2 in the Supplemental Information for financial and statistical information for these portfolios.

See the Glossary for further information and reconciliation to Aimco’s Supplemental Information.

Conventional Same Store Results – In first quarter 2010, the Conventional Same Store portfolio included 170 communities with 56,770 units, in which Aimco had a weighted average ownership of 92%.

AIMCO 1st Quarter 2010 Page 2

Comparing Conventional Same Store results in first quarter 2010 with first quarter 2009, total revenue decreased $3.1 million, or 1.8%. The decrease in revenue was primarily the result of lower average rent, down 5.5% or $59 per unit, from $1,065 per unit to $1,006 per unit, largely offset by higher average daily occupancy of 96.0% for first quarter 2010 compared to 93.3% for first quarter 2009. Rental rates on new leases transacted during the quarter were 7.0% lower than the expiring lease rates, while renewal rates were 0.1% higher than the expiring lease rates. New and renewal lease rates improved throughout the quarter, with March 2010 new lease rates 5.1% lower than the expiring lease rates and renewal rates 0.4% higher than the expiring lease rates. Conventional Same Store expenses increased $2.6 million or 3.9%, primarily due to increased snow removal costs in the Northeast, repairs and maintenance, and marketing expenses, partially offset by lower turn costs and administrative expenses. Refer to Supplemental Schedules 6a and 6b for additional details on Conventional Same Store operating results.

Portfolio

Aimco’s portfolio strategy focuses on B/B+ quality Conventional apartment communities located in the 20 largest U.S. markets, with a target capital allocation of 10% or less to Affordable apartment communities.

Aimco measures Conventional property asset quality based on average rents compared to local market average rents as reported by REIS, a third-party provider of commercial real estate performance information and analysis. Aimco defines A-quality assets as those with rents greater than 125% of local market average, B-quality assets as those with rents 90% to 125% of local market average and C-quality assets as those with rents less than 90% of local market average. For the fourth quarter 2009, the most current period for which REIS information is available, Aimco’s Conventional property rents averaged 103% of local market average rents.

For the first quarter 2010, average rents for the Conventional portfolio were $1,034 per unit, a 0.5% increase compared to first quarter 2009, primarily as a result of the sale of Conventional properties during 2009 with rents averaging 25% less than the retained portfolio.

Aimco’s geographic allocation strategy focuses on the 20 largest U.S. markets as measured by total apartment value. Aimco believes these markets to be deep, relatively liquid and possessing desirable long-term growth characteristics. These target markets are primarily coastal markets, and also include a number of Sun Belt cities and Chicago, Illinois. As Aimco executes this strategy, the company expects to reduce its investment in markets outside the 20 largest markets and to increase its investment in the 20 largest markets through redevelopment and acquisitions. During first quarter 2010, net operating income generated by Conventional properties located in the 20 largest markets accounted for 82.8% of total Conventional property net operating income, an increase of 2.9% compared to first quarter 2009.

In first quarter 2010, Aimco sold four Conventional properties and eight Affordable properties with 789 and 834 units, respectively, for $82.6 million in gross proceeds. Aimco’s share of net proceeds after distributions to limited partners, repayment of existing property debt and transaction costs was $17.1 million. Proceeds were used primarily to repay recourse term debt.

See Supplemental Schedules 7a and 7b for additional details regarding Aimco’s portfolio quality and capital allocation, and Supplemental Schedule 8 for additional details on disposition activity.

AIMCO 1st Quarter 2010 Page 3

Aimco’s recourse debt is limited to its revolving credit facility and corporate term debt, which together represented approximately 1% of Aimco’s leverage at the end of first quarter 2010. At that time, the balance on Aimco’s revolving credit facility was $14.8 million and available capacity was $121.4 million, net of $43.8 million of letters of credit drawn against the facility. Aimco’s revolving credit facility is used for working capital purposes and to secure letters of credit. The balance on Aimco’s corporate term debt of $45.0 million at March 31, 2010, matures in first quarter 2011. Subsequent to quarter’s end, Aimco repaid $10.0 million of the term debt, bringing the balance to $35.0 million at the end of April 2010.

In connection with its recourse obligations, Aimco is subject to Debt Service and Fixed Charge Coverage covenants, as defined in the Glossary. For first quarter 2010, Aimco’s Debt Service and Fixed Charge Coverage ratios were 1.59:1 and 1.35:1, compared to covenants in place during the quarter of 1.40:1 and 1.20:1, respectively, and fourth quarter 2009 ratios of 1.59:1 and 1.36:1. Aimco expects to remain in compliance with these covenants.

Net Asset Value Supplemental Information

[1]	Real estate includes Lincoln Place and Pacific Bay Vistas (formerly Treetops), which are predominantly vacant and have March 31, 2010, net book values of $142.3 million and $33.7 million, respectively, or $176.0 million in total. Aimco refers to these properties collectively as its redevelopment pipeline.
[2]	Aimco has notes receivable from consolidated partnerships that are eliminated in the GAAP balance sheet. The noncontrolling partners’ share of amounts payable to Aimco pursuant to those notes is added to the GAAP-based amounts to arrive at the proportionate balance presented.
[3]	Aimco’s internal NAV estimate is computed based on Aimco’s share of NOI and as such takes into account Aimco’s share of NOI attributable to unconsolidated partnerships. For this reason, investment in unconsolidated real estate partnerships is excluded from non-real estate assets in Aimco’s internal NAV computation.
[4]	Deferred financing costs, goodwill and investment in management contracts represent non-tangible assets for which cash has already been paid by Aimco. As such, these amounts are excluded from Aimco’s internal NAV computation.
[5]	Deferred income consists primarily of cash contributions received in connection with Aimco’s tax credit activities, which are deferred upon receipt and amortized into earnings in future periods as the tax credits and related tax benefits are delivered to the tax credit investors. Certain of Aimco’s tax credit arrangements provide for contributions to be made in installments, which contributions are not reflected in Aimco’s consolidated financial statements until such time as the contributions are received.
	Deferred income, including deferred tax credit income, represents a non-cash obligation, the amortization of which represents non-cash income in future periods. These non-cash liabilities and related income streams are excluded from Aimco’s internal estimates of NAV. However, amortization of deferred tax credit income is included in net income and, as such, FFO. Projected amortization of deferred tax credit contributions received and to be received is presented below.

(unaudited)

Aimco’s portfolio strategy focuses on B/B+ quality apartment communities located in the 20 largest U.S. markets as measured by total apartment value, with a target allocation to Conventional Properties of 90% or more. Aimco measures Conventional Property asset quality based on average rents compared to local market average rents as reported by REIS, with A-quality assets earning rents greater than 125% of local market average, B-quality assets earning rents 90% to 125% of local market average and C-quality assets earning rents less than 90% of local market average. Aimco’s geographic allocation strategy focuses on the 20 largest U.S. markets, with market quality measured in part based on long-term growth characteristics.

The following schedule illustrates Aimco’s Conventional Property portfolio quality and market growth projections based on 4Q 2009 data, as this is the most recent period for which third-party data is available.

Notes

[1]	NOI Cap Rate is calculated based on the trailing twelve month NOI prior to sale, less a 3.5% management fee, divided by the gross proceeds. Prior to 1Q 2010, Aimco provided a Free Cash Flow cap rate on this schedule, which represented an NOI cap rate assuming a 5% management fee and an adjustment of $300 per door for capital replacements.
[2]	Net Sales Proceeds are after repayment of existing debt, net working capital settlements, payment of transaction costs and prepayment penalties.
[3]	Year-to-date, Aimco has disposed of Conventional Properties in the following markets:

Capital Additions
(in thousands, except per unit data) (unaudited)

All capital additions are classified as either Capital Replacements (“CR”), Capital Improvements (“CI”), redevelopment or casualties. Non-redevelopment and non-casualty capital additions are apportioned between CR and CI based on the useful life of the capital item under consideration and the period Aimco has owned the property (i.e., the portion that was consumed during Aimco’s ownership of the item represents CR; the portion of the item that was consumed prior to Aimco’s ownership represents CI). See the Glossary for further descriptions.

Amounts below represent actual additions related to residential properties that are owned and managed by Aimco at the end of the period. These amounts include consolidated and unconsolidated properties and are not adjusted for Aimco’s ownership interest in such properties. Amounts do not include capital additions related to:

• properties sold during the period or properties held for sale at the end of the period;

• properties that are not multi-family such as commercial properties or fitness facilities; and

• properties that Aimco owns but does not manage.

See the Glossary for a reconciliation of these amounts to GAAP capital additions.

Glossary and Reconciliations of Non-GAAP Financial and Operating Measures

This Earnings Release and Supplemental Information include certain financial measures used by Aimco management that are not calculated in accordance with accounting principles generally accepted in the United States of America, or GAAP. Aimco’s definition and calculation of these non-GAAP financial and operating measures and other terms may differ from the definitions and methodologies used by other REITs and, accordingly, may not be comparable. These non-GAAP financial and operating measures should not be considered an alternative to GAAP net income or any other GAAP measurement of performance and should not be considered an alternative measure of liquidity.

ACQUISITION PROPERTIES: Properties that have been acquired during the twelve months prior to the current quarter-end that have not reached a stabilized level of occupancy during the current period and each period for which comparable results are presented.

ADJUSTED FUNDS FROM OPERATIONS (AFFO): AFFO is Pro forma FFO, as defined below, less Capital Replacement additions, also defined below, adjusted for the Aimco Operating Partnership’s share of such Capital Replacements. Similar to FFO, AFFO is helpful to investors in understanding Aimco’s performance because it captures features particular to real estate performance by recognizing that real estate generally appreciates over time or maintains residual value to a much greater extent than do other depreciating assets such as machinery, computers or other personal property. There can be no assurance that Aimco’s method for computing AFFO is comparable with that of other real estate investment trusts.

AFFORDABLE PROPERTIES: Affordable Properties benefit from governmental programs intended to provide housing to people with low or moderate incomes. These programs, which are usually administered by the U.S. Department of Housing and Urban Development, or HUD, or state housing finance agencies, typically provide mortgage insurance, favorable financing terms, tax-credit equity, or rental assistance payments to the property owners. Under these programs, rent adjustments are made in accordance with property-specific contracts between Aimco and HUD, with rent increases generally based on an adjustment factor set by HUD annually. Aimco targets an investment in Affordable Properties of 10% or less of Net Asset Value, which serves to offset the volatility of our Conventional portfolio; provide revenue growth that over time is similar to that of Conventional Properties; expand our investment opportunities; and provide helpful positioning with government bodies, benefiting Aimco’s business overall.

AIMCO OPERATING PARTNERSHIP: AIMCO Properties, L.P., a Delaware limited partnership, is the operating partnership in Aimco’s UPREIT structure. Aimco owns approximately 93% of the common partnership units of the Aimco Operating Partnership.

AIMCO PROPORTIONATE FINANCIAL INFORMATION: Non-GAAP measures representing Aimco’s share of financial information discussed in this Earnings Release and Supplemental Information. Aimco’s proportionate share of financial information includes Aimco’s share of unconsolidated real estate partnerships and excludes noncontrolling interests in consolidated real estate partnerships. Proportionate reporting benefits the users of Aimco’s financial information by providing the amount of revenues, expenses, assets and liabilities attributable only to Aimco stockholders. Aimco also refers to this measure as “Aimco’s Share” of financial information. See Supplemental Schedules 1, 3 and 4 for reconciliation of Aimco’s proportionate share of financial results to Aimco’s consolidated financial statements.

CAPITAL ADDITIONS DEFINITIONS AND RECONCILIATION

CAPITAL IMPROVEMENTS (CI): CI additions include all non-redevelopment capital additions that are made to enhance the value, profitability or useful life of an asset from its original purchase condition.

CAPITAL REPLACEMENTS (CR): Unlike CI additions, CR additions do not increase the value, profitability or useful life of an asset from its original purchase condition. They represent the share of additions that are deemed to replace the consumed portion of acquired capital assets. CR additions are deducted in the calculation of AFFO.

CASUALTY CAPITAL ADDITIONS: Capitalized costs incurred in connection with casualty losses and are associated with the restoration of the asset. A portion of the restoration costs is reimbursed by insurance carriers net of deductibles associated with each loss.

AIMCO 1st Quarter 2010 Page 16

Supplemental Schedule 9 contains capital additions information related to (1) residential properties that Aimco owns and manage at the end of the period, (2) properties that are consolidated in Aimco’s GAAP financial statements, and (3) properties that are accounted for under the equity method of accounting in Aimco’s GAAP financial statements. Amounts do not include capital additions related to:

• consolidated properties sold during the period or properties held for sale at the end of the period;

• consolidated properties that are not multi-family such as commercial properties or fitness facilities; or

• consolidated properties that Aimco owns but does not manage.

Aimco believes the capital addition detail provided in Supplemental Schedule 9 provides an enhanced understanding of capital additions related to our primary business of owning and operating apartment communities. A reconciliation of capital additions presented on Supplemental Schedule 9 to Aimco’s consolidated GAAP information is presented below.

	Three Months Ended
(in thousands) (unaudited)	March 31, 2010
Capital Additions per Schedule 9	$	34,938
Capital additions related to:
Unconsolidated real estate partnerships		(96	)
Consolidated sold and held for sale properties		298
Consolidated properties that are not multi-family, such as commercial properties or fitness facilities		13
Consolidated properties Aimco owns but does not manage		404
Consolidated capital additions	$	35,557

CONVENTIONAL PROPERTIES: Conventional Properties represent Aimco’s portfolio of market-rate apartment communities. Aimco focuses on owning and operating apartment communities with rents that are 100% to 125% of local market average rents and concentrates its investment in the 20 largest apartment markets in the United States, as measured by apartment value. Aimco targets an investment in Conventional Properties of 90% or more of Net Asset Value.

DEBT SERVICE COVERAGE RATIO: As defined in Aimco’s credit agreement, the ratio of (a) Aimco’s adjusted total earnings before interest, taxes, depreciation and amortization (which is reduced by certain capital expenditure reserves) to (b) the actual debt service, for the four fiscal quarters preceding the date of calculation.

EFFECTIVE UNITS: Unit count at 100% ownership multiplied by Aimco’s ownership share. Effective Units may be used to analyze Aimco proportionate financial measures on a per-unit basis.

EARNINGS BEFORE INTEREST, TAXES, DEPRECIATION AND AMORTIZATION (EBITDA): EBITDA is equal to Aimco’s adjusted total earnings before interest, taxes, depreciation and amortization as defined in Aimco’s credit agreement before capital addition reserves provided for in Aimco’s credit agreement. EBITDA is the numerator used in Aimco’s calculation of EBITDA Coverage of Interest Ratio and EBITDA Coverage of Preferred Dividends and Interest Ratio.

EBITDA COVERAGE OF INTEREST RATIO: The ratio of (a) Aimco’s EBITDA to (2) total interest expense charges, as provided for in Aimco’s credit agreement, for the four fiscal quarters preceding the date of calculation. This ratio is similar to Aimco’s Debt Service Coverage Ratio with the exception that Aimco’s EBITDA Coverage of Interest Ratio does not include capital addition reserves in the numerator and does not include debt amortization or capitalized interest in the denominator, while Debt Service Coverage Ratio does include these items. Aimco’s credit agreement does not contain any compliance thresholds for the EBITDA Coverage of Interest Ratio; however, Aimco management uses this ratio as one measure of leverage.

AIMCO 1st Quarter 2010 Page 17

EBITDA COVERAGE OF INTEREST AND PREFERRED DIVIDENDS RATIO: The ratio of (a) Aimco’s EBITDA to (2) the sum of total interest expense and dividends/distributions on preferred shares/units, as provided for in Aimco’s credit agreement, for the four fiscal quarters preceding the date of calculation. This ratio is similar to Aimco’s Fixed Charge Coverage Ratio with the exception that Aimco’s EBITDA Coverage of Interest and Preferred Dividends Ratio does not include capital addition reserves in the numerator and does not include debt amortization or capitalized interest in the denominator, while Fixed Charge Coverage Ratio does include these items. Aimco’s credit agreement does not contain any compliance thresholds for the EBITDA Coverage of Interest and Preferred Dividends Ratio; however, Aimco management uses this ratio as one measure of leverage.

FIXED CHARGE COVERAGE RATIO: As defined in Aimco’s credit agreement, the ratio of (a) Aimco’s adjusted total earnings before interest, taxes, depreciation and amortization (which is reduced by certain capital expenditure reserves) to (b) fixed charges, which represents the sum of total interest expense, debt amortization and dividends/distributions on preferred shares/units, for the four fiscal quarters preceding the date of calculation.

FEE MANAGED PROPERTIES: Aimco provides property management and/or asset management services for a portfolio of properties, primarily pursuant to long-term arrangements with affiliated parties. In certain cases, Aimco may indirectly own generally less than one percent of the operations of such properties through a partnership syndication or other fund.

FUNDS FROM OPERATIONS (FFO): FFO is a commonly used measure of REIT performance, which the National Association of Real Estate Investment Trusts (NAREIT) defines as net income, computed in accordance with GAAP, excluding gains from sales of depreciable property, plus depreciation and amortization, and after adjustments for unconsolidated partnerships and joint ventures. Aimco computes FFO for all periods presented in accordance with the guidance set forth by NAREIT’s April 1, 2002 White Paper.

In addition to FFO, Aimco uses PRO FORMA FUNDS FROM OPERATIONS (Pro forma FFO) to measure performance. Pro forma FFO represents FFO as defined above, excluding operating real estate impairments and preferred stock redemption related amounts (adjusted for noncontrolling interests). Both operating real estate impairment losses and preferred stock redemption related amounts are recurring items that affect Aimco’s operating results. Operating real estate impairment losses, net of related income tax benefits and noncontrolling interests, are excluded from Pro forma FFO because Aimco believes the inclusion of such losses in FFO is inconsistent with the treatment of gains on the disposition of operating real estate, which are not included in FFO. Aimco excludes preferred redemption related amounts (gains or losses) from Pro forma FFO because such amounts are not representative of operating results.

FFO and Pro forma FFO are helpful to investors in understanding Aimco’s performance because they capture features particular to real estate performance by recognizing that real estate generally appreciates over time or maintains residual value to a much greater extent than do other depreciating assets such as machinery, computers or other personal property. There can be no assurance that Aimco’s method for computing FFO is comparable with that of other real estate investment trusts. Net income (loss) attributable to Aimco common stockholders as determined in accordance with GAAP is reconciled to FFO as presented on Supplemental Schedule 1 below.

OTHER AFFORDABLE PROPERTIES: Affordable Properties that do not meet the Same Store property definition because (1) the property is under redevelopment, (2) the property is not managed by Aimco, and/or (3) Aimco’s ownership in the property is less than 10%.

OTHER CONVENTIONAL PROPERTIES: Conventional Properties that have significant rent control restrictions, university housing properties and properties that are not multi-family such as commercial properties or fitness facilities.

OTHER EXPENSES, NET: Other expenses, net includes franchise taxes, risk management activities related to our unconsolidated partnerships, certain other corporate expenses and partnership expenses (partnership level expenses incurred directly or indirectly for services such as audit, tax and legal).

PROPERTY NET OPERATING INCOME (NOI): NOI is defined by Aimco as total property rental and other property revenues less direct property operating expenses, including real estate taxes. NOI does not include: property management revenues, primarily from affiliates; casualties; off-site property management expenses; depreciation; or interest expense. NOI is helpful because it helps both investors and management to understand the operating performance of real estate excluding costs associated with decisions about acquisition pricing, overhead allocations and financing arrangements. NOI is considered by many in the real estate industry to be a useful measure for determining the value of real estate. A reconciliation of NOI as presented in this Earnings Release and Supplemental Information to Aimco’s consolidated GAAP amounts is provided on the following page.

REDEVELOPMENT PROPERTIES: Properties where (1) a substantial number of available units have been vacated for major renovations or have not been stabilized in occupancy for at least one year as of the earliest period presented, or (2) other significant renovation, such as exteriors, common areas or unit improvements (done upon lease expirations), is underway or has been complete for less than one year, as of the earliest period presented. In both cases the properties have been removed from the Same Store portfolio. Redevelopment properties are classified as either Conventional or Affordable. Aimco combines Affordable Redevelopment Properties with Other Affordable Properties for financial reporting purposes within its Supplemental Schedules 1 and 2.

SAME STORE PROPERTIES: Same Store properties are those properties (1) that are managed by Aimco, (2) in which Aimco’s ownership exceeds 10%, and (3) that have reached and maintained a stabilized level of occupancy during the current period and each period for which comparable results are presented. Same Store properties are classified as either Conventional or Affordable and properties classified in the consolidated financial statements as held for sale are not included in Same Store. To ensure comparability between periods, the proportionate Conventional Same Store information shown on Supplemental Schedules 6a and 6b is based on Aimco’s current period ownership.
