Actual results may differ materially from those described in these forward-looking statements and, in addition, will be affected by a variety of risks and factors, some of which are beyond the control of Aimco, including, without limitation: financing risks, including the availability and cost of capital markets financing and the risk that our cash flows from operations may be insufficient to meet required payments of principal and interest; earnings may not be sufficient to maintain compliance with debt covenants; real estate risks, including fluctuations in real estate values and the general economic climate in the markets in which we operate and competition for residents in such markets; national and local economic conditions; the terms of governmental regulations that affect Aimco and interpretations of those regulations; the competitive environment in which Aimco operates; the timing of acquisitions and dispositions; insurance risk, including the cost of insurance; natural disasters and severe weather such as hurricanes; litigation, including costs associated with prosecuting or defending claims and any adverse outcomes; energy costs; 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 Aimco. In addition, our current and continuing qualification as a real estate investment trust involves the application of highly technical and complex provisions of the Internal Revenue Code and depends on our ability to meet the various requirements imposed by the Internal Revenue Code, through actual operating results, distribution levels and diversity of stock ownership.

Atlanta Boston Chicago Dallas-Fort Worth Denver East Bay Houston Los Angeles Manhattan Miami Orange County Other Target Florida Markets Philadelphia Phoenix San Diego San Francisco San Jose Seattle Suburban New York/New Jersey Washington - NoVA - MD 20 Markets represent 85% of national apartment market cap* * Source: PPR as of 12/31/2009. Capital Allocation Strategy Concentrate capital in 20 target markets

16 Capital Recycling Strategy Reinvestment: Increase investment in conventional assets located in priority markets. Redevelopment and enhancement of existing assets. Acquisition of B/B+ quality assets. Continually improve portfolio through capital recycling Objectives: Increase Aimco rents compared to local market averages. Provide for higher rental rate growth. Dispositions: Sell 5 - 10% of lowest-rated assets annually. Reduce affordable portfolio to 10% of NAV.

17 Conventional Portfolio Transformation Excludes casualties and property management expenses. NOI less assumed capital replacement expenditures of $850 per unit. Sale of lower-rated assets have improved overall portfolio quality. Further asset sales will be pursued only if accretive investment opportunities exist.

18 Aimco Growth Drivers Aimco has the opportunity to grow through internal and external resources Internal: Rent growth - Aimco projected revenue growth is consistent with peers. Redevelopment - Aimco has a pipeline of assets that have the potential to generate yields at a premium to acquisitions. Financial leverage - In a rising market, financial leverage magnifies positive results. External: Acquisitions - Aimco can fund acquisitions: in the property debt markets with equity raised by selling assets with rents below our portfolio average or by issuing common shares Capital markets - Aimco has the opportunity to restructure maturing property debt and lock in historically low interest rates for the next ten years.

Aimco's dividend has room to grow with a current pay-out of approximately 45% of AFFO. Upside opportunities for Aimco stockholders:

20 2010 Property Operations Objectives Maximize revenues while reducing costs Average Daily Occupancy (ADO) - Maintain ADO above 95% with continued high resident quality standards. Year-to-date 2010 ADO was 95.8%. Rates - Take advantage of higher demand markets with higher occupancies to increase rates using revenue management tools. Renewals - Stay focused on the residents we already have. Renewals will remain a major focus for all properties. Service - Service will remain a high priority. We will continue resident touch point programs in support of retention of current residents. Expenses - Continued strong focus on expense control activities. We expect on-site productivity gains, lower marketing cost per lead and reductions in contract service costs through aggressive vendor management. We will continue to invest capital in maintaining our properties with NO reduction in our per door spend for repairs and maintenance and capital replacements.

21 Diversified Portfolio Reduces Volatility During 2009, NOI was essentially flat across our diversified portfolio. Expect 2010 total portfolio NOI to be -0.5% to 0.5% compared to 2009. Stability of Affordable NOI provides offset to volatility in Conventional Same Store NOI. Lease-up of short cycle redevelopment business offset Conventional Same Store NOI decline over the past year. Over the coming quarters, this benefit will be reduced as virtually all redevelopment units were on-line at the end of 1Q 2010.

22 2010 Same-Store Portfolio Performance

23 History of Competitive Operating Results Operating performance exceeds peer average on a year-to-date basis and over the last one, three and five years. * * Represents the average of results reported by AvalonBay, Camden, Equity Residential, Essex, Home Properties and UDR.

24 Property Operations Update Rental rates for renewals have been positive since February. Strong Average Daily Occupancy provides support for rental rates. August 2010 ADO was 96.2%. Rental rates for new leases remain negative compared to rental rates on expiring leases, but the rate of decline has eased and is positive in many markets.

25 Consistent Investment in Physical Assets Sustained rate of reinvestment in asset quality, notwithstanding the economy. Invested approximately $2.2 billion in the portfolio since 2005. Continued investment in properties through: Planned Replacement Program Energy investments Redevelopment where appropriate

26 Aimco Balance Sheet Non-recourse debt ? limited entity risk. Single-property loans with 60% initial LTV. Discipline of amortization to <50% LTV at maturity. Long-dated, laddered maturities. Primarily fixed interest rates. Assumable by buyers. Perpetual preferred securities ? no refunding and very limited re- pricing risk, with only $37 million subject to a potential rate reset in 2015. Property debt and perpetual preferred securities provide balance sheet safety

27 Aimco Financing Strategy For purposes of this analysis, peer group is comprised of Camden, Equity Residential, Essex, Home Properties, UDR. Data as of 6/30/2010 as reported by SNL Financial. Represents balances as of June 30, 2010 adjusted for July 2010 repayment of remaining balance of $25 million of term debt. Aimco is financed primarily with long-term, fixed-rate, non-recourse, amortizing property debt with a weighted-average interest rate of 5.5%. Weighted-average maturity of debt of eight years is more than 30% longer than Aimco's apartment peer average(1). Perpetual preferred stock and preferred partnership units carry a weighted- average dividend rate of 7.6%. No recourse debt.

28 Improving Coverage to Target Target leverage: EBITDA coverage of interest: 2.25x EBITDA coverage of interest and preferred dividends: 1.80x Current leverage: EBITDA coverage of interest: 2.04x EBITDA coverage of interest and preferred dividends: 1.67x Improve coverage, primarily through cyclical NOI recovery, and from scheduled debt amortization. Coverage targets expected to be met within the next three to four years. Aimco expects to improve coverages to target levels over the next three to four years

29 2010 Balance Sheet & Liquidity Uses largely balanced with internal sources of cash. No debt maturities in 2010. Limited 2011 maturities ($105 million). 2010 property debt activity will focus on loans maturing in 2012 to 2014 to lock in current low interest rates. Line of credit is unused and available, except for short-term borrowings and collateralized letters of credit. Liquidity is strong
