PRELIMINARY 2022 OUTLOOK – Basis for Expectations at the midpoint This preliminary outlook represents the midpoint of AIR’s current expectations. Please see page 5 for assumptions regarding Same Store revenue, expense, and NOI expectations. Please see pages 6 and 7 for additional context. Please see pages 8-11 for additional context. Expected year-over-year incremental contributions from 2021 acquisitions. See pages 12-14 for examples of value creation for properties added to the AIR operating platform. Property NOI lost from $1.7 billion of 2021 dispositions, largely offset by interest savings from $1.1 billion reduction in leverage, refinancing of other debt, and contribution from 2021 acquisitions. Please see pages 15-17 for information regarding AIR leverage relative to peers. Please see page 18 for a comparison of AIR’s cost structure relative to peers. Lease income is expected to increase in 2022 due to addition of two leases. Interest income declines by $0.03 year-over-year due to 2021 maturity of AIR’s “B-piece” from “old Aimco” debt securitization. Contribution from $600 million of 2022 acquisitions: $380 million during 1Q funded with borrowing using capacity created by 2021 dispositions $220 million during 1H funded with paired trades The preliminary 2022 outlook presented herein provides a reasonable expectation based on what we know now, including the midpoint of 2021 Same Store guidance. As is practice, AIR will provide 2022 guidance early in 2022. This guidance may well differ from these estimates due to external events such as changes in interest rates, incremental government intervention related to the pandemic, changes in the economy, or other factors.

Slide 5

PRELIMINARY 2022 OUTLOOK: Same Store NOI UP 12.0% at the midpoint Represents expectations for 2022 market rate growth, bad debt recovery, and other ancillary revenue items. Controllable operating expenses expected to be flat at the mid-point. Net utilities, insurance, and taxes are expected to grow by 430 to 510 basis points. +7.6% - 11.0% Earn-in of 2021 Lease Rates +2.2% +1.0% Anticipated Occupancy Uplift Other Factors (1) +0.6% - 4.0% Earn-in of current Market rates +3.8% Revenue Growth +7.6% - 11.0% Total Expenses (2) +2.0% - 2.8% NOI Growth +9.5% - 14.5%

Slide 12

AIR Platform Value Creation results when properties are first added to the AIR Platform NOI growth rates exceed market growth rates by 10% to 15% during the first two to four years, before reversion to long-term trend. This initial outperformance increases long-term IRRs from 6% to ~10%. In 2018, AIR acquired Bent Tree and four properties in Philadelphia, investing $468 million. In the two years following acquisition, NOI growth, net of the cost of capital to fund capital improvements, outperformed market growth by 11% annually. In 2021, AIR also acquired five properties, investing $750 million. During the next two years, NOI growth, net of the cost of capital to fund capital improvements, is expected to outperform market growth by 16% annually.

AIR leverage will be below peer average As of 3Q 2021 per company filings. Leverage to EBITDA (1)

Slide 16

AIR’s net cost of debt is peer-leading Peer data per company filings. AIR net cost of debt adjusted for planned payoffs. AIR’s cost of debt is currently reduced by a $534 million note receivable from Aimco. AIR intends to use the proceeds from the note repayment to reduce leverage. Adjusted for repayment of the note, AIR’s cost of debt is expected to be ~2.5% with a weighted average maturity of 7.6 years. Cost of Debt (1) (2)

Slide 17

Interest expense for peers computed based on leverage and weighted average cost of debt as reported in 3Q 2021 company filings. AIR net interest expense as computed based on expected year-end balances and estimated weighted average net cost. Same Store NOI for peers computed based on full year 2020 Same Store NOI grown at mid-point of full year guidance per 3Q 2021 company filings. AIR’s interest expense as a percentage of Same Store NOI is currently reduced by interest earned on the note receivable from Aimco. Adjusted for repayment of the note, AIR estimates its interest expense as a percentage of Same Store NOI would be 14%. Interest Expense % of Same Store NOI (1)(2) There are certain limitations when comparing the percentage of interest expense to various measures of cash flow among the peer group, among them: AIR has income streams in addition to Same Store NOI, such as lease income and NOI from its acquisition properties. Peers also have income streams in addition to Same Store NOI, such as development, mezzanine lending programs, and condominium sales. Utilizing Same Store NOI provides a rough, but the most readily available, basis for comparison of the relative importance of interest expense given that the same store portfolio represents the largest part of each peers’ business.

Air’s efficient G&A structure Increases shareholder returns Peer data per Green Street. AIR G&A as a percentage of GAV is presented as calculated utilizing the methodology outlined on page 21. This methodology differs from Green Street, which estimates AIR G&A at 11 bps of GAV. G&A as Percentage of GAV (1) (2) Large Cap MF REIT Average 20 basis points AIR measures G&A efficiency by dividing G&A costs by Gross Asset Value (“GAV”). AIR’s target is 15 basis points or below. Compensation earned by the CEO will be subordinated, if necessary, to meet this metric.

Slide 21

AIR definition of G&A and GAV One of AIR’s strategic objectives is to provide an efficient cost structure as measured by G&A as a percentage of assets. AIR’s target is 15 bps points or below. AIR intends to routinely track and report on this metric. Additionally, compensation earned by the CEO will be subordinated if necessary to meet this metric. Determination of GAV: For any calendar year, AIR intends to use a weighted average of quarterly estimates. Acquisitions and dispositions are included in the determination of GAV in the period the transaction occurs. Determination of G&A expenses: All costs that are reported as G&A costs in our GAAP income statement.  Property management costs in excess of 3% of Property Revenues; eliminating any distortion from allocation of costs. Asset Management fees earned from joint ventures serve to reduce G&A costs. Asset Management fees are paid by joint venture partners in reimbursement of G&A services provided by AIR. AIR has determined that certain costs previously included in “other expenses” and “non-real estate depreciation” in supplemental schedule 2 to our earnings release are more appropriately considered as G&A expenses, and as such will be including these costs in G&A in future reporting periods. CEO has agreed to subordinate compensation to achieve G&A of 15 basis points. Amount is based on AIR’s current estimate of quarterly GAV. Year-end GAV has been reduced to reflect the $1.7 billion of estimated 4Q 2021 dispositions. Green Street’s estimated GAV, adjusted for dispositions is $12.9 billion. 2021 G&A Expenses, before asset management income (25,400,000) Reclassification of costs previously included in "other expense" and non-real estate depreciation (1) (2,110,000) (27,510,000) Estimated 2021 asset management income 4,500,000 Reimbursed by Aimco 5,800,000 (17,210,000) Estimated Property Management expenses in excess of property management income (3,500,000) (20,710,000) Estimated costs in excess of 15 basis points (2) 1,200,000 (19,510,000) Estimated average GAV (3) 13,000,000,000 G&A as a % of average GAV 0.15% Comparison to Green Street Green Street also regularly tracks and reports on this metric. Using GSA’s methodology, AIR’s G&A as percentage of assets is 11bps. Green Street’s determination of G&A expense differs from AIR’s method. Green Street estimates G&A expenses based on a forward 12-month estimate. This estimate is based on company provided guidance, historical trends, and their judgment. AIR’s calculation is based on current year expectations. It is important to note that both AIR and Green Street include, within G&A, Property Management costs in excess of 3% of revenues. In computing GAV, AIR uses a weighted average of quarterly estimates. Acquisitions and dispositions are reflected in GAV in the period the transaction occurs. Green Street uses a spot estimate based on their current GAV estimate.
