2. Fee Income Fee income - a consistent source of annual income, where Aimco has the expertise and asset base to drive income growth: Generated from tax credit syndication, dispositions, refinancings Tax credit business is a sizable piece of the real estate industry at $5 billion/year Aimco owned properties are captive pipeline of ongoing activity Strong pipeline increases predictability of income stream Year to date, awarded 10 tax credit allocations for $52 million compared with 7 and $34 million, respectively in 2004 Grow the business: Market size is significant. Industry-wide more than $5B in tax credit equity invested annually for more than 100,000 units/year Aimco Capital is uniquely positioned with a national structure and management team

4. Portfolio Management Investing in desirable markets yet maintaining focus on long-term value Concentrate portfolio in fewer markets Reduce from 65 to approximately 38 markets, targeting by the end of 2008 Currently considering further consolidation resulting in fewer markets Expect to exit 8 markets in 2005 By year-end 2006, Aimco expects that 85% of conventional NAV will be comprised of properties located in coastal markets, the Mountain West and Chicago Capital recycling focused on reinvesting to build NAV

5. Entitlement Realize upside in land values through increasing density of use Aimco portfolio of B and C properties in A locations provides deep pipeline of opportunities Older properties built at lower densities Focus on locations where land is scarce Underlying land value may be greater than current improved value Currently have a number of active entitlement projects Potential increase in NAV due solely to rezoning Significant upside potential Takes time to recognize value in earnings by land sale income or profitable redevelopment Year-to-date progress includes Spring Hill Lake - proposed density increase from 2,899 units to 5,800 units where land value is estimated at $65k-$80k/unit 3 projects: in Scottsdale, AZ; San Bruno, CA; and Venice, CA are on track to receive combined increased densities of approximately 500 units

6. Cost of Capital Floating rate exposure Partially offset by floating rate assets Variability < $0.02/quarter based on Bloomberg compilations Leverage level good Aimco's capital structure is by design Property level debt offers the lowest risk WACC among lowest of REITs Capitalization plan To fund expanded redevelopment effort through refinancing existing property debt, construction borrowing and sales of Non Core properties Seek to reduce corporate debt while increasing average property LTVs to 60-65% We plan to use non-recourse property debt to fund the bulk of redevelopment spending and to refund corporate borrowings

7. G&A / Productivity We are very focused on driving a disciplined approach to expense controls through process and technology improvements Actions will reduce G&A and operating costs in 2006 Focus on process, automation and routinization to increase efficiency and take advantage of scale Continue to enhance budget and forecasting processes to provide improved visibility and accountability Consider appropriate sourcing including offshoring Systems Projects HFM/Essbase eProcurement PROs

D. 2006 Strategy Going into 2006, Aimco will be focused on: Property operations: Leveraging higher occupancy to drive increased rent. Disciplined expense control Fee income: Growing tax credit redevelopment stream to improve asset quality and generate continued strong fee income Redevelopment: Executing expanded program of value creation under Tim Beaudin Portfolio Management: Selling Non Core properties and reinvesting proceeds to generate higher returns through redevelopment, redemption of high cost preferreds and possibly share repurchases Entitlement: Completing active projects and realizing benefits to NAV and FFO Cost of Capital: Funding growth through property level borrowings, refinancings with targeted LTVs to 60-65% and proceeds from sale of Non Core properties while reducing corporate level borrowings G&A/Productivity: Begin realizing savings in G&A from investments in people, systems and processes as implemented in 2005 and continuing in 2006
