FORWARD-LOOKING STATEMENTS This presentation contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. These forward-looking statements, which are based on current expectations, estimates and projections about the industry and markets in which MAA operates and beliefs of and assumptions made by MAA management, involve uncertainties that could significantly affect the financial results of MAA. Words such as “expects,” “anticipates,” “intends,” “plans,” “believes,” “seeks,” “estimates,” and variations of such words and similar expressions are intended to identify such forward-looking statements, which are not historical in nature. In this presentation, forward-looking statements include, but are not limited to, statements about forecasted operating results, the outlook for new supply, expected benefits and synergies from the merger with Post Properties, Inc. and the timing of those benefits and synergies, anticipated occupancy rates, the anticipated value of current development projects and lease-up communities, estimated costs of property development, the anticipated timing of completion of current development projects and the stabilization of such projects, MAA’s future development projects, the anticipated stabilization of communities in lease-up, the anticipated scope of MAA’s future redevelopment activities and projected redevelopment costs and incremental rent growth, and other information that is not historical. All statements that address operating performance, events or developments that MAA anticipates or expects will occur in the future are forward-looking statements. These statements are not guarantees of future performance and involve certain risks, uncertainties and assumptions that are difficult to predict. Although MAA believes the expectations reflected in any forward-looking statements are based on reasonable assumptions, MAA can give no assurance that its expectations will be achieved, and therefore actual outcomes and results may differ materially from what is expressed or forecasted in such forward-looking statements. Some of the factors that may affect outcomes and results include, but are not limited to: inability to generate sufficient cash flows due to market conditions, changes in supply and/or demand, competition, uninsured losses, changes in tax and housing laws, or other factors; exposure as a multifamily-focused REIT to risks inherent in investments in a single industry and sector; adverse changes in real estate markets; failure of new acquisitions to achieve anticipated results or be efficiently integrated; failure of development communities to be completed, if at all, within budget and on a timely basis or to lease-up as anticipated; unexpected capital needs; changes in operating costs, including real estate taxes, utilities and insurance costs; losses from catastrophes in excess of our insurance coverage; level and volatility of interest or capitalization rates or capital market conditions; the effect of any rating agency actions; inability to attract and retain qualified personnel; cyberliability or potential liability for breaches of our privacy or information security systems; adverse legislative or regulatory tax changes; adverse legal proceedings; compliance costs associated with laws requiring access for disabled persons; and those additional risks and factors discussed in reports filed with the Securities and Exchange Commission by MAA from time to time, including those discussed under the heading “Risk Factors” in MAA’s most recently filed Annual Report on Form 10-K and Quarterly Reports on Form 10-Q. MAA undertakes no duty to update any forward-looking statements appearing in this presentation.

Third party data suggests that the supply outlook for our markets will show modest improvement with market level supply expected to decline slightly from deliveries in 2018 Our internal budgeting process takes this data and further identifies the new supply expected to most impact our properties, i.e. identify supply within a certain radius of our properties as opposed to market level or submarket level supply While the more targeted supply picture varies from the market level supply in some metros, overall we similarly expect some decline in supply for our portfolio as compared to 2018 Assuming the demand outlook (job growth) stays similar to what we have seen in 2018, we think this suggests some improvement in revenue fundamentals in 2019 as compared to 2018 2019 SUPPLY OUTLOOK 7 Current 2019 Targeted Supply Outlook MAA Portfolio Source: Axiometrics , Internal data

2019 FFO CONSIDERATIONS Our current 2018 FFO guidance includes several non - core or non - recurring items, detailed below: • Debt mark to market credit adjustment of $9.5M to $10.5M (credit to FFO) • Life insurance settlement of $4.4M (credit to FFO) • Land sale gains of $3.9M (credit to FFO) • Debt extinguishment gains of $2.4M related to expected debt payoffs (credit to FFO) • Merger/integration costs of $8.5M to $10M (debit to FFO) • Total FFO impact in 2018 of $11.5 million at the midpoint; or approximately $0.10 per share Also, in our Q3 earnings release, we reduced our acquisition guidance from $325 million at the midpoint to $104.5 million. While this change has a minimal impact on 2018 FFO, it does impact our 2019 FFO expectations. Currently, for 2019 FFO, we expect: • Debt mark to market adjustment of $300k (credit to FFO ); and essentially $0 beyond 2019. While it is non - cash, the reduction in this mark to market credit adjustment from 2018 to 2019 will add approximately 20bps to our 2019 effective interest rate • Minimal activity in any of the other non - core items mentioned above that are impacting 2018 FFO • Normalizing year over year expense growth as the comparative benefit of Post expense synergies diminishes, and our expectatio n of continued upward pressure on labor costs will impact personnel and upward pressure on property values will impact real est ate taxes • Normalizing overhead costs (G&A and property management) – 2018 overhead reflected some non - recurring items that benefited 2018 expense as well as some open positions that are expected to be fully staffed now that the integration is complete • Our updated overhead guidance for 2018 is $7 million lower than our original guidance, which was already inclusive of capturi ng $20 million of merger overhead synergies • 2019 overhead to reflect more of a normal increase off of original 2018 expectations 18

As an owner and operator of real estate, MAA considers Adjusted EBITDAre to be an important measure of performance from core operations because Adjusted EBITDAre does not include various income and expense items that are not indicative of operating performance. MAA's computation of Adjusted EBITDAre may differ from the methodology utilized by other companies to calculate Adjusted EBITDAre . Adjusted EBITDAre should not be considered as an alternative to Net income available for MAA common shareholders as an indicator of financial performance. Adjusted Funds From Operations (AFFO) AFFO is composed of FFO less recurring capital expenditures. In order to better align the classification of capital expenditu res with business goals, certain capital expenditures related to commercial properties have been reclassified out of recurring capital expenditures fo r c omparative purposes. AFFO should not be considered as an alternative to Net income available for MAA common shareholders. As an owner and operato r o f real estate, MAA considers AFFO to be an important measure of performance from operations because AFFO measures the ability to control rev enu es, expenses and recurring capital expenditures. EBITDA For purposes of calculations in this release, Earnings Before Interest, Income Taxes, Depreciation and Amortization, or EBITDA, i s c omposed of net income plus depreciation and amortization, interest expense, and income taxes.

EBITDA should not be considered as an alternative to Net income available for MAA common shareholders as an indicator of financial performance . EBITDA re For purposes of calculations in this release, Earnings Before Interest, Income Taxes, Depreciation and Amortization for real est ate, or EBITDAre , is composed of EBITDA, as defined above, excluding the gain or loss on sale of depreciable asset sales and plus adjustments to r efl ect MAA's share of EBITDAre of unconsolidated affiliates. As an owner and operator of real estate, MAA considers EBITDAre to be an important measure of performance from core operations because EBITDAre does not include various expense items that are not indicative of operating performance. While MAA's definition of EBITDAre is in accordance with NAREIT's definition, it may differ from the methodology utilized by other companies to calculate EBITDAre . EBITDAre should not be considered as an alternative to Net income available for MAA common shareholders as an indicator of financial p er formance. 27

DEFINITIONS OF NON - GAAP FINANCIAL MEASURES Funds Available for Distribution (FAD) FAD is composed of FFO less total capital expenditures, excluding development spending and property acquisitions. FAD should not be considered as an alternative to Net income available for MAA common shareholders.

Because noncontrolling interest is added back, FFO, when used in this document, represents FFO attributable to the Company. While MAA's definition of FFO is in accordance with the N ARE IT's definition, it may differ from the methodology for calculating FFO utilized by other REITs and, accordingly, may not be comparable to such other RE ITs. FFO should not be considered as an alternative to Net income available for MAA common shareholders as an indicator of operating performance. M AA believes that FFO is helpful in understanding operating performance in that FFO excludes depreciation and amortization of real estate asset s. MAA believes that GAAP historical cost depreciation of real estate assets is generally not correlated with changes in the value of those assets , w hose value does not diminish predictably over time, as historical cost depreciation implies . Gross Assets Gross Assets represents Total assets plus Accumulated depreciation and accumulated depreciation for Assets held for sale, whi ch is included in "Assets held for sale" on the Consolidated Balance Sheets. MAA believes that Gross Assets can be used as a helpful tool in e val uating its balance sheet positions. MAA believes that GAAP historical cost depreciation of real estate assets is generally not correlated with cha nges in the value of those assets, whose value does not diminish predictably over time, as historical cost depreciation implies . Gross Real Estate Assets Gross Real Estate Assets represents Real estate assets, net plus Accumulated depreciation and accumulated depreciation for As set s held for sale, which is included in "Assets held for sale" on the Consolidated Balance Sheets, plus Cash and cash equivalents plus 1031(b) e xch ange proceeds included in "Restricted cash" on the Consolidated Balance Sheets.

NOI should not be considered as an alternative to Net in com e available for MAA common shareholders. MAA believes NOI by market is a helpful tool in evaluating the operating performance within MAA's marke ts because it measures the core operations of property performance by excluding corporate level expenses and other items not related to pro per ty operating performance . Recurring Adjusted EBITDA re Recurring Adjusted EBITDAre represents Adjusted EBITDAre further adjusted to exclude certain items that are not considered part of MAA's core business operations such as acquisition and merger and integration expenses. MAA believes Recurring Adjusted EBITDAre is an important performance measure as it adjusts for certain items that by their nature are not comparable over periods and therefore tend t o o bscure actual operating performance. MAA's definition of Recurring Adjusted EBITDAre may differ from the methodology utilized by other companies to calculate Recurring Adjusted EBITDAre . Recurring Adjusted EBITDAre should not be considered as an alternative to Net income available for MAA common shareholders as an indicator of operating performance . Same Store NOI Same Store NOI represents total operating revenues less total property operating expenses, excluding depreciation, for all pr ope rties classified within the Same Store Portfolio during the period. Same Store NOI should not be considered as an alternative to Net income available fo r MAA common shareholders.
