Consolidation And Basis Of Presentation And Significant Accounting Policies [Abstract]
Organization and Summary of Significant Accounting Policies	1. Organization and Summary of Significant Accounting Policies Unless the context otherwise requires, all references to the “Company” refer collectively to Mid-America Apartment Communities, Inc., together with its consolidated subsidiaries, including Mid-America Apartments, L.P. Unless the context otherwise requires, all references to “MAA” refer only to Mid-America Apartment Communities, Inc., and not any of its consolidated subsidiaries. Unless the context otherwise requires, the references to the “Operating Partnership” or “MAALP” refer to Mid-America Apartments, L.P. together with its consolidated subsidiaries. “Common stock” refers to the common stock of MAA and, unless the context otherwise requires, “shareholders” refers to the holders of shares of MAA’s common stock. The common units of limited partnership interests in the Operating Partnership are referred to as “OP Units,” and the holders of the OP Units are referred to as “common unitholders”. As of December 31, 2019, MAA owned 114,246,393 OP Units (or 96.6% of the total number of OP Units). MAA conducts substantially all of its business and holds substantially all of its assets, directly or indirectly, through the Operating Partnership, and by virtue of its ownership of the OP Units and being the Operating Partnership's sole general partner, MAA has the ability to control all of the day-to-day operations of the Operating Partnership. Management believes combining the notes to the consolidated financial statements of MAA and the Operating Partnership results in the following benefits: • enhances a readers' understanding of MAA and the Operating Partnership by enabling the reader to view the business as a whole in the same manner that management views and operates the business; • eliminates duplicative disclosure and provides a more streamlined and readable presentation since a substantial portion of the disclosure applies to both MAA and the Operating Partnership; and • creates time and cost efficiencies through the preparation of one combined set of notes instead of two separate sets. MAA, an S&P 500 company, is a multifamily-focused, self-administered and self-managed real estate investment trust, or REIT. Management operates MAA and the Operating Partnership as one business. The management of the Company is comprised of individuals who are officers of MAA and employees of the Operating Partnership. Management believes it is important to understand the few differences between MAA and the Operating Partnership in the context of how MAA and the Operating Partnership operate as a consolidated company. MAA and the Operating Partnership are structured as an umbrella partnership REIT, or UPREIT. MAA's interest in the Operating Partnership entitles MAA to share in cash distributions from, and in the profits and losses of, the Operating Partnership in proportion to MAA's percentage interest therein and entitles MAA to vote on substantially all matters requiring a vote of the partners. MAA's only material asset is its ownership of limited partnership interests in the Operating Partnership (other than cash held by MAA from time to time); therefore, MAA’s primary function is acting as the sole general partner of the Operating Partnership, issuing public equity from time to time and guaranteeing certain debt of the Operating Partnership. The Operating Partnership holds, directly or indirectly, all of the Company's real estate assets. Except for net proceeds from public equity issuances by MAA, which are contributed to the Operating Partnership in exchange for limited partnership interests, the Operating Partnership generates the capital required by the business through the Operating Partnership's operations, direct or indirect incurrence of indebtedness and issuance of OP Units. The presentations of MAA's shareholders' equity and the Operating Partnership's capital are the principal areas of difference between the consolidated financial statements of MAA and those of the Operating Partnership. MAA's shareholders' equity may include shares of preferred stock, shares of common stock, additional paid-in capital, cumulative earnings, cumulative distributions, noncontrolling interest, treasury shares, accumulated other comprehensive income and redeemable common stock. The Operating Partnership's capital may include common capital and preferred capital of the general partner (MAA), limited partners' common capital and preferred capital, noncontrolling interest, accumulated other comprehensive income and redeemable common units. Holders of OP Units (other than MAA) may require the Operating Partnership to redeem their OP Units from time to time, in which case the Operating Partnership may, at its option, pay the redemption price either in cash (in an amount per OP Unit equal, in general, to the average closing price of MAA's common stock on the New York Stock Exchange, or NYSE, over a specified period prior to the redemption date) or by delivering one share of MAA's common stock (subject to adjustment under specified circumstances) for each OP Unit so redeemed. Organization of Mid-America Apartment Communities, Inc. The Company owns, operates, acquires and selectively develops apartment communities primarily located in the Southeast, Southwest and Mid-Atlantic regions of the United States. As of December 31, 2019, the Company owned and operated 299 apartment communities through the Operating Partnership and its subsidiaries and had an ownership interest in one apartment community through an unconsolidated real estate joint venture. As of December 31, 2019, the Company had seven development communities under construction totaling 2,108 apartment units. Total expected costs for the seven development projects are $489.5 million, of which $ million had been incurred through December 31, 2019 . The Company expects to complete one de velopment in the first half of 2020, one development in the second half of 2020 , one development in the first half of 2021, three developments in the second half of 2021, and one development in the first half of 2022 . of the Company's apartment communities include retail components with approximately square feet of gross leasable space. The Company also has four commercial properties with approximately 260,000 square feet of combined gross leasable area. The Company’s apartment communities and commercial properties are located across states and the District of Columbia. Basis of Presentation and Principles of Consolidation The accompanying consolidated financial statements have been prepared by the Company's management in accordance with United States generally accepted accounting principles, or GAAP, and applicable rules and regulations of the Securities and Exchange Commission, or the SEC. The consolidated financial statements of MAA presented herein include the accounts of MAA, the Operating Partnership and all other subsidiaries in which MAA has a controlling financial interest. MAA owns, directly or indirectly, approximately 80% to 100% of all consolidated subsidiaries, including the Operating Partnership. The consolidated financial statements of MAALP presented herein include the accounts of MAALP and all other subsidiaries in which MAALP has a controlling financial interest. MAALP owns, directly or indirectly, 80% to 100% of all consolidated subsidiaries. In management's opinion, all adjustments necessary for a fair presentation of the consolidated financial statements have been included, and all such adjustments were of a normal recurring nature. All significant intercompany accounts and transactions have been eliminated in consolidation. The Company invests in entities which may qualify as variable interest entities, or VIEs, and MAALP is considered a VIE. A VIE is a legal entity in which the equity investors lack sufficient equity at risk for the entity to finance its activities without additional subordinated financial support or, as a group, the holders of the equity investment at risk lack the power to direct the activities of a legal entity as well as the obligation to absorb its expected losses or the right to receive its expected residual returns. MAALP is classified as a VIE because the limited partners lack substantive kick-out rights and substantive participating rights. The Company consolidates all VIEs for which it is the primary beneficiary and uses the equity method to account for investments that qualify as VIEs but for which it is not the primary beneficiary. In determining whether the Company is the primary beneficiary of a VIE, management considers both qualitative and quantitative factors, including, but not limited to, those activities that most significantly impact the VIE's economic performance and which party controls such activities. The Company uses the equity method of accounting for its investments in entities for which the Company exercises significant influence, but does not have the ability to exercise control. The factors considered in determining whether the Company has the ability to exercise control include ownership of voting interests and participatory rights of investors (see “Investments in Unconsolidated Affiliates” below). Changes in Presentation In order to simplify the Company's presentation of cash flows from financing activities within the Consolidated Statements of Cash Flows, the Company combined “Repurchase of common stock / units”; “Debt prepayment and extinguishment costs”; “Proceeds from issuances of common shares / units”; and “Exercise of stock / unit options” into one line, “Net change in other financing activities” within the cash flows from financing activities section. No presentation changes were made to the cash flows from operating or investing activities sections of the Consolidated Statements of Cash Flows. Prior year amounts have been changed to conform to the Company's current year presentation. These changes in presentation had no effect on the Company's ending cash, cash equivalents and restricted cash balances and did not impact the classification of cash flows between operating, investing and financing activities. Noncontrolling Interests As of December 31, 2019, the Company had two types of noncontrolling interests with respect to its consolidated subsidiaries, (1) noncontrolling interests related to the common unitholders of its Operating Partnership and (2) noncontrolling interests related to its consolidated real estate entities. The noncontrolling interests relating to the limited partnership interests in the Operating Partnership are owned by the holders of the Class A OP Units. MAA is the sole general partner of the Operating Partnership and holds all of the outstanding Class B OP Units. Net income (after allocations to preferred ownership interests) is allocated to MAA and the noncontrolling interests based on their respective ownership percentages of the Operating Partnership. Issuance of additional Class A OP Units or Class B OP Units changes the ownership percentage of both the noncontrolling interests and MAA. The issuance of Class B OP Units generally occurs when MAA issues common stock and the issuance proceeds are contributed to the Operating Partnership in exchange for Class B OP Units equal to the number of shares of MAA's common stock issued. At each reporting period, the allocation between total MAA shareholders’ equity and noncontrolling interests is adjusted to account for the change in the respective percentage ownership of the underlying equity of the Operating Partnership. MAA’s Board of Directors established economic rights in respect to each Class A OP Unit that were equivalent to the economic rights in respect to each share of MAA common stock. See Note 9 for additional details. The noncontrolling interests relating to the Company’s consolidated real estate entities are owned by private real estate companies that are generally responsible for the development and construction of the apartment communities that are owned through the consolidated real estate entities with a noncontrolling interest. The entities were determined to be VIE’s with the Company designated as the primary beneficiary. As a result, the accounts of the entities are consolidated by the Company. During the year ended December 31, 2019, the Company acquired a partial ownership interest in two consolidated real estate entities and acquired the noncontrolling interest of one consolidated real estate entity for cash proceeds of $ 10.9 million. As of December 31, 2019, the consolidated assets and liabilities of the Company’s consolidated real estate entities with a noncontrolling interest were $ million and $ 3.2 million, respectively. As of December 31, 2018, the consolidated assets and liabilities of the Company’s consolidated real estate entity with a noncontrolling interest were $ 85.7 million and $ 1.3 million, respectively. Use of Estimates Management has made a number of estimates and assumptions relating to the reporting of assets and liabilities, the disclosure of contingent assets and liabilities, and the reported amounts of revenues and expenses to prepare these financial statements and notes in conformity with GAAP. Actual results could differ from those estimates. Rental Costs Costs associated with rental activities are expensed as incurred and include advertising expenses, which were $20.8 million, $20.2 million, and $18.8 million for the years ended December 31, 2019, 2018 and 2017, respectively. Real Estate Assets and Depreciation and Amortization Real estate assets are carried at depreciated cost and consist of land, buildings and improvements and other and development and capital improvements in progress (see “Development Costs” below). Repairs and maintenance costs are expensed as incurred, while significant improvements, renovations and recurring capital replacements are capitalized and depreciated over their estimated useful lives. Recurring capital replacements typically include scheduled carpet replacement, new roofs, HVAC units, plumbing, concrete, masonry and other paving, pools and various exterior building improvements. In addition to these costs, the Company also capitalizes salary costs directly identifiable with renovation work. These expenditures extend the useful life of the property and increase the property’s fair market value. The cost of interior painting and blinds are typically expensed as incurred. Depreciation is computed on a straight-line basis over the estimated useful lives of the related assets, which range from five to 40 years. The Consolidated Balance Sheets line “Buildings and improvements and other” includes land improvements and buildings, which have a useful life ranging from eight to 40 years, as well as furniture, fixtures and equipment, which have a useful life of five years. Development Costs Development projects and the related carrying costs, including interest, property taxes, insurance and allocated direct development salary costs during the construction period, are capitalized and reported in the accompanying Consolidated Balance Sheets as “Development and capital improvements in progress” during the construction period. Interest is capitalized in accordance with accounting standards governing the capitalization of interest. Upon completion and certification for occupancy of individual buildings or floors within a development, amounts representing the completed portion of total estimated development costs for the project are transferred to “Buildings and improvements and other” as real estate held for investment. Capitalization of interest, property taxes, insurance and allocated direct development salary costs cease upon the transfer. The assets are depreciated over their estimated useful lives. Total capitalized costs (including capitalized interest, salaries and real estate taxes) during the years ended December 31, 2019, 2018 and 2017 were $6.5 million, $4.2 million and $11.0 million, respectively. Certain costs associated with the lease-up of development projects, including cost of model units, furnishings and signs, are capitalized and amortized over their respective estimated useful lives. All other costs relating to renting development projects are expensed as incurred. Acquisition of Real Estate Assets In accordance with Accounting Standards Codification, or ASC, Topic 805, Business Combinations The purchase price of an acquired property is allocated based on the relative fair value of the individual components as a proportion of the total assets acquired. The Company allocates the cost of the tangible assets of an acquired property by valuing the building as if it were vacant, based on management’s determination of the relative fair values of these assets. Management determines the as-if-vacant fair value of a building using methods similar to those used by independent appraisers. These methods include using stabilized net operating income, or NOI, and market specific capitalization and discount rates. In allocating the cost of identified intangible assets of an acquired property, the in-place leases are valued based on current rent rates and time and cost to lease a unit. Management concluded that the residential leases acquired in connection with each of its property acquisitions approximate at-market rates since the residential lease terms generally do not extend beyond one year. For residential leases, the fair value of the in-place leases and resident relationships is amortized over six months, which represents the estimated remaining term of the tenant leases. For retail and commercial leases, the fair value of in-place leases and tenant relationships is amortized over the remaining term of the leases. The net amount of these lease intangibles included in “Other assets” totaled $2.6 million and $3.9 million as of December 31, 2019 and 2018, respectively. Impairment of Long-lived Assets The Company accounts for long-lived assets in accordance with the provisions of accounting standards for the impairment or disposal of long-lived assets. Management periodically evaluates long-lived assets, including investments in real estate, for indicators that would suggest that the carrying amount of the assets may not be recoverable. The judgments regarding the existence of such indicators are based on factors such as operating performance, market conditions and legal factors. Long-lived assets, such as real estate assets, equipment and purchased intangibles subject to amortization, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to estimated undiscounted future cash flows expected to be generated by the asset. If the carrying amount of an asset exceeds its estimated future cash flows, an impairment charge is recognized for the amount by which the carrying amount of the asset exceeds the fair value of the asset. Assets to be disposed of are separately presented in the Consolidated Balance Sheets and reported at the lower of the carrying amount or fair value less costs to sell, and are no longer depreciated. The assets and liabilities of a disposed group or a property classified as held for sale are presented separately in the appropriate asset and liability sections of the Consolidated Balance Sheets. Undeveloped Land Undeveloped land includes sites intended for future multifamily developments, sites for future commercial development and sites intended for residential use, which are carried at the lower of cost or fair value in accordance with GAAP. Any costs incurred prior to commencement of pre-development activities are expensed as incurred. Investments in Unconsolidated Affiliates The Company uses the equity method to account for its investments in a real estate joint venture and a limited partnership that both qualify as a VIE. Management determined the Company is not the primary beneficiary in either investment but does have the ability to exert significant influence over the operations and financial policies of the real estate joint venture and considers its investment in the limited partnership to be more than minor. As of December 31, 2019 and 2018, the Company's investment in the real estate joint venture was $43.7 million and $44.2 million, respectively. As of December 31, 2019 and 2018, the Company's investment in the limited partnership was $13.1 million and $3.8 million, respectively, and is included in “Other assets” in the accompanying Consolidated Balance Sheets. As of December 31, 2019, the Company was committed until September 2022 to make additional capital contributions totaling $8.2 million if and when called by the general partner of the limited partnership. Cash and Cash Equivalents Investments in money market accounts and certificates of deposit with original maturities of three months or less are considered to be cash equivalents. Restricted Cash Restricted cash consists of security deposits required to be held separately, escrow deposits held by lenders for property taxes, insurance, debt service and replacement reserves, and exchanges under Section 1031(b) of the Internal Revenue Code of 1986, as amended, or the Code. Section 1031(b) exchanges are presented within cash, cash equivalents and restricted cash reported in the Consolidated Statements of Cash Flows. Other Assets Other assets consist primarily of receivables and deposits from residents, the value of derivative contracts, right-of-use lease assets, investment in a limited partnership, deferred rental concessions, deferred financing costs relating to a revolving credit facility and other prepaid expenses. Also included in other assets are the fair market value of in-place leases and resident relationships, net of accumulated amortization. Accrued Expenses and Other Liabilities Accrued expenses consist of accrued dividends payable, accrued real estate taxes, accrued interest payable, accrued loss contingencies (see Note 11), accounts payable, right-of-use lease liabilities, security deposits not related to restricted cash, other accrued expenses, and unearned income. Significant accruals include accrued dividends payable of $118.3 million and $113.2 million as of December 31, 2019 and 2018, respectively; accrued real estate taxes of $131.9 million loss contingencies of $ 8.6 million and $ 8.7 million as of December 31, 2019 and 2018 , respectively; security deposits of $ 19.4 million and $ 18.7 million as of December 31, 2019 and 2018 , respectively; and accrued interest payable of $ 21.4 million and $ million as of December 31, 2019 and 2018 , respectively. Income Taxes MAA has elected to be taxed as a REIT under the Code and intends to continue to operate in such a manner. The current and continuing qualification as a REIT depends on MAA's ability to meet the various requirements imposed by the Code, which are related to organizational structure, distribution levels, diversity of stock ownership and certain requirements with respect to the nature and diversity of MAA’s assets and sources of MAA’s gross income. As long as MAA qualifies for taxation as a REIT, it will generally not be subject to United States federal corporate income tax on its taxable income that is currently distributed to shareholders. This treatment substantially eliminates the “double taxation” (i.e., income taxation at both the corporate and shareholder levels) that generally results from an investment in a corporation. Even if MAA qualifies as a REIT, MAA may be subject to United States federal income and excise taxes in certain situations, such as if MAA fails to distribute timely all of its taxable income with respect to a taxable year. MAA also will be required to pay a 100% tax on any net income on non-arm’s length transactions between MAA and one of its taxable REIT subsidiaries, or TRS. Furthermore, MAA and its shareholders may be subject to state or local taxation in various state or local jurisdictions, including those in which MAA transacts business or its shareholders reside, and the applicable state and local tax laws may not conform to the United States federal income tax treatment. Any taxes imposed on MAA would reduce its operating cash flows and net income. The Company has elected TRS status for certain of its corporate subsidiaries. As a result, the TRS incur both federal and state income taxes on any taxable income after consideration of any net operating losses. The TRS use the liability method of accounting for income taxes. Deferred income tax assets and liabilities are recognized for future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities from a change in tax rate is recognized in earnings in the period of the enactment date. A valuation allowance is provided when it is more likely than not that all or some portion of the deferred tax assets will not be realized. The Company recognizes liabilities for uncertain income tax positions based on a two-step process. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates that it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation processes, if any. The second step requires the Company to estimate and measure the tax benefit as the largest amount that is more likely than not to be realized upon ultimate settlement. See Note 7 for additional disclosures regarding income taxes. Fair Value Measurements The Company applies the guidance in ASC Topic 820, Fair Value Measurements and Disclosures Level 1 - Quoted prices in active markets for identical assets or liabilities that are accessible at the measurement date. Level 2 - Inputs other than quoted prices that are observable for the asset or liability, either directly or indirectly. Level 3 - Unobservable inputs for the assets or liability. Leases In 2016, the Financial Accounting Standards Board, or FASB, issued Accounting Standard Update, or ASU, 2016-02, Leases Comparative periods presented in this Annual Report on Form 10-K continue to apply guidance in ASC Topic 840, Leases, revenues as the Company's residential, retail and commercial leases, where it is the lessor, will continue to be accounted for as operating leases. Management has elected available practical expedients that provide lessors an option not to separate lease and non-lease components when certain criteria are met, and instead, allow for those components to be accounted for as a single lease component. B eginning with the effective date of the adoption of the new standard, rental revenues and non-lease reimbursable property revenues meet the criteria to be aggregated into a single lease component and are reported in the line item, “ Rental revenues ” , as presented in the disaggregation of the Company's revenues in Note 13. The Company is the lessee under certain ground, office, equipment and other operating leases. Based on its election of the package of practical expedients provided in ASU 2016-02, the Company did not reassess the classification of existing leases with its adoption of ASC Topic 842. The Company’s existing leases as of January 1, 2019 have continued to be accounted for as operating leases; however, if contracts are modified subsequent to the adoption of the new standard, the Company is required to reassess the contracts using guidance provided under ASC Topic 842. The Company recognized total right-of-use assets of $54.3 million within “Other assets” and related lease obligations of $33.6 million within “Accrued expenses and other liabilities” in its Consolidated Balance Sheets for leases in effect as of January 1, 2019. As of December 31, 2019, right-of-use assets and the related lease obligations totaled $53.8 million and $33.1 million, respectively. As most leases do not provide a readily determinable implicit rate to discount future minimum lease payments to present value, management estimated the Company's incremental borrowing rate based on information available as of the date of adoption and based on the remaining lease terms as of the date of initial application. Operating leases recognized upon adoption had a weighted-average remaining lease term of approximately 33 years and management estimated a weighted-average discount rate of approximately 4.4%. Operating leases as of December 31, 2019 have a weighted-average remaining lease term of approximately 32 years and a weighted-average discount rate of approximately 4.4%. Lease expense recognized for the years ended December 31, 2019, 2018 and 2017 was immaterial to the Company and was recognized in a similar manner for all years presented. Cash paid for amounts included in the measurement of operating lease liabilities during the year ended December 31, 2019 was also immaterial. Revenue Recognition The Company primarily leases multifamily residential apartments under operating leases generally due on a monthly basis with terms of approximately one year or less, which are recorded as operating leases. Rental revenues are recognized in accordance with ASC Topic 842 using a method that represents a straight-line basis over the term of the lease. In addition, in circumstances where a lease incentive is provided to tenants, the incentive is recognized as a reduction of rental revenues on a straight-line basis over the reasonably assured lease term. Rental revenues represent approximately 93% of the Company's total revenues and include gross rents charged less adjustments for concessions and bad debt. Approximately 6% of the Company's total revenues represents reimbursable property revenues from its tenants for utility reimbursements, which are generally recognized and due on a monthly basis as tenants obtain control of the service over the term of the lease. The remaining 1% of the Company's total revenues represents other non-lease revenues primarily driven by nonrefundable fees and commissions. With the adoption of ASC Topic 842, rental revenues and non-lease reimbursable property revenues meet the criteria to be aggregated into a single lease component and are reported on a combined basis, while non-lease reimbursable property revenues recognized prior to January 1, 2019 is reported as non-lease revenues and recognized in accordance with ASC Topic 606, Revenue Recognition. Recently Issued Accounting Pronouncements In June 2016, the FASB issued ASU No. 2016-13, Measurement of Credit Losses on Financial Instruments

Earnings Per Common Share Of M A A [Abstract]
Earnings per Common Share of MAA	2 . Earnings per Common Share of MAA Basic earnings per share is computed by dividing net income available to MAA common shareholders by the weighted average number of common shares outstanding during the period. All outstanding unvested restricted share awards contain rights to non-forfeitable dividends and participate in undistributed earnings with shareholders and, accordingly, are considered participating securities that are included in the two-class method of computing basic earnings per share. Both the unvested restricted shares and other potentially dilutive common shares, and the related impact to earnings, are considered when calculating earnings per share on a diluted basis with diluted earnings per share being the more dilutive of the treasury stock or two-class methods. OP Units are included in dilutive earnings per share calculations when the units are dilutive to earnings per share. For the years ended December 31, 2019, 2018 and 2017, MAA's diluted earnings per share was computed using the treasury stock method as presented below (dollars and shares in thousands, except per share amounts): 2019 2018 2017 Calculation of Earnings per common share - basic Net income $ 366,618 $ 231,022 $ 340,536 Net income attributable to noncontrolling interests (12,807 ) (8,123 ) (12,157 ) Unvested restricted stock (allocation of earnings) (519 ) (291 ) (535 ) Preferred dividends (3,688 ) (3,688 ) (3,688 ) Net income available for MAA common shareholders, adjusted $ 349,604 $ 218,920 $ 324,156 Weighted average common shares - basic 113,854 113,638 113,407 Earnings per common share - basic $ 3.07 $ 1.93 $ 2.86 Calculation of Earnings per common share - diluted Net income $ 366,618 $ 231,022 $ 340,536 Net income attributable to noncontrolling interests (12,807 ) (1) (8,123 ) (1) (12,157 ) (1) Preferred dividends (3,688 ) (3,688 ) (3,688 ) Net income available for MAA common shareholders, adjusted $ 350,123 $ 219,211 $ 324,691 Weighted average common shares - basic 113,854 113,638 113,407 Effect of dilutive securities 259 198 280 Weighted average common shares - diluted 114,113 113,836 113,687 Earnings per common share - diluted $ 3.07 $ 1.93 $ 2.86 (1)

Earnings per OP Unit of MAALP	3 . Earnings per OP Unit of MAALP Basic earnings per common unit is computed using the two-class method by dividing net income available for common unitholders by the weighted average number of OP Units outstanding during the period. All outstanding unvested restricted unit awards contain rights to non-forfeitable distributions and participate in undistributed earnings with common unitholders and, accordingly, are considered participating securities that are included in the two-class method of computing basic earnings per common unit. Diluted earnings per common unit reflects the potential dilution that could occur if securities or other contracts to issue OP Units were exercised or converted into OP Units. Both the unvested restricted unit awards and other potentially dilutive common units, and the related impact to earnings, are considered when calculating earnings per common unit on a diluted basis with diluted earnings per common unit being the more dilutive of the treasury stock or two-class methods.

Stock-Based Compensation

Stock Based Compensation [Abstract]
Stock-Based Compensation	4 . Overview MAA accounts for its stock-based employee compensation plans in accordance with accounting standards governing stock-based compensation. These standards require an entity to measure the cost of employee services received in exchange for an award of an equity instrument based on the award's fair value on the grant date and recognize the cost over the period during which the employee is required to provide service in exchange for the award, which is generally the vesting period. Any liability awards issued are remeasured at each reporting period. MAA’s stock compensation plans consist of a number of incentives provided to attract and retain independent directors, executive officers and key employees. Incentives are currently granted under the Second Amended and Restated 2013 Stock Incentive Plan, or the Stock Plan, which was approved at the 2018 annual meeting of MAA shareholders. The Stock Plan allows for the grant of restricted stock and stock options up to 2,000,000 shares. MAA believes that such awards better align the interests of its employees with those of its shareholders. Compensation expense is generally recognized for service based restricted stock awards using the straight-line method over the vesting period of the shares regardless of cliff or ratable vesting distinctions. Compensation expense for market and performance based restricted stock awards is generally recognized using the accelerated amortization method with each vesting tranche valued as a separate award, with a separate vesting date, consistent with the estimated value of the award at each period end. Additionally, compensation expense is adjusted for actual forfeitures for all awards in the period that the award was forfeited. Compensation expense for stock options is generally recognized on a straight-line basis over the requisite service period. MAA presents stock compensation expense in the Consolidated Statements of Operations in “General and administrative expenses”. Total compensation expense under the Stock Plan was $14.7 million, $12.9 million and $10.8 million for the years ended December 31, 2019, 2018 and 2017, respectively. Of these amounts, total compensation expense capitalized was $1.0 million, $0.5 million and $0.2 million for the years ended December 31, 2019, 2018 and 2017, respectively. As of December 31, 2019, the total unrecognized compensation expense was $13.9 million. This cost is expected to be recognized over the remaining weighted average period of 0.9 years. Total cash paid for the settlement of plan shares totaled $3.7 million, $2.9 million and $4.8 million for the years ended December 31, 2019, 2018 and 2017, respectively. Information concerning grants under the Stock Plan is provided below. Restricted Stock In general, restricted stock is earned based on either a service condition, performance condition, or market condition, or a combination thereof, and generally vests ratably over a period from at grant date to 5 years. Service based awards are earned when the employee remains employed over the requisite service period and are valued on the grant date based upon the market price of MAA common stock on the date of grant. Market based awards are earned when MAA reaches a specified stock price or specified return on the stock price (price appreciation plus dividends) and are valued on the grant date using a Monte Carlo simulation. Performance based awards are earned when MAA reaches certain operational goals, such as funds available for distribution targets, and are valued based upon the market price of MAA common stock on the date of grant as well as the probability of reaching the stated targets. MAA remeasures the fair value of the performance based awards each balance sheet date with adjustments made on a cumulative basis until the award is settled and the final compensation is known. The weighted average grant date fair value per share of restricted stock awards granted during the years ended December 31, 2019, 2018 and 2017, was $72.98, $71.85 and $84.53, respectively. The following is a summary of the key assumptions used in the valuation calculations for market based awards granted during the years ended December 31, 2019, 2018 and 2017: 2019 2018 2017 Risk free rate 2.578% 1.61% - 2.14% 0.65% - 1.57% Dividend yield 4.043% 3.884% 3.573% Volatility 18.95% 15.05% - 17.18% 20.43% - 21.85% Requisite service period 3 years 3 years 3 years The risk free rate was based on a zero coupon risk-free rate. The dividend yield was based on the closing stock price of MAA stock on the date of grant. Volatility for MAA was obtained by using a blend of both historical and implied volatility calculations. Historical volatility was based on the standard deviation of daily total continuous returns, and implied volatility was based on the trailing month average of daily implied volatilities interpolating between the volatilities implied by stock call option contracts that were closest to the terms shown and closest to the money. The requisite service period is based on the criteria for the separate programs according to the vesting schedule. For the years ended December 31, 2018 and 2017, the minimum risk free rate was based on a period of 0.25 years 3 years A summary of the status of the nonvested restricted shares as of December 31, 2019, and the changes for the year ended December 31, 2019, is presented below: Nonvested Shares Shares Weighted Average Grant-Date Fair Value Nonvested as of January 1, 2019 187,777 $ 88.79 Issued 173,174 88.59 Vested (125,381 ) 74.35 Forfeited (1,692 ) 95.44 Nonvested as of December 31, 2019 233,878 $ 96.33 The total fair value of shares vested during the years ended December 31, 2019, 2018 and 2017 was $9.3 million, $7.6 million and $10.5 million, respectively. Stock Options Stock options are earned when the employee remains employed over the requisite service period and vest ratably over a period from 0.3 years to 2.3 years. Stock options exercised result in new common shares being issued on the open market by the Company. The fair value of stock option awards is determined using the Monte Carlo valuation model. No stock options were granted during the years ended December 31, 2019, 2018 or 2017. A summary of the status of the outstanding stock options as of December 31, 2019 and the changes for the year ended December 31, 2019 is presented below: Stock Options Options Weighted Average Exercise Price Outstanding as of January 1, 2019 90,615 $ 77.16 Granted — — Exercised (69,852 ) 76.96 Expired — — Outstanding as of December 31, 2019 20,763 $ 77.82 All options outstanding as of December 31, 2019 were exercisable and had an intrinsic value of $1.2 million with a weighted average remaining term of 5.2 years. There were 69,852 options, 17,823 options and 21,006 options exercised during the years ended December 31, 2019, 2018 and 2017, respectively. Cash received from the exercise of stock options totaled $2.9 million, $0.9 million and $0.4 million for the years ended December 31, 2019, 2018 and 2017, respectively.

Fair Value Disclosures [Abstract]
Financial Instruments and Derivatives	6 . Financial Instruments and Derivatives Financial Instruments Not Carried at Fair Value Cash and cash equivalents, restricted cash and accrued expenses and other liabilities are carried at amounts that reasonably approximate their fair value due to their short term nature. Fixed rate notes payable as of December 31, 2019 and December 31, 2018, totaled $4.1 billion and $3.1 billion, respectively, and had estimated fair values of $4.5 billion and $3.1 billion (excluding prepayment penalties) as of December 31, 2019 and December 31, 2018, respectively. The carrying values of variable rate debt (excluding the effect of interest rate swap agreements) as of December 31, 2019 and December 31, 2018, totaled $0.4 billion and $1.1 billion, respectively, and had estimated fair values of $0.4 billion and $1.1 billion (excluding prepayment penalties) as of December 31, 2019 and December 31, 2018, respectively. The fair values of fixed rate debt are determined by using the present value of future cash outflows discounted with the applicable current market rate plus a credit spread. The fair values of variable rate debt are determined using the stated variable rate plus the current market credit spread. The variable rates reset every 30 to 90 days, and management concluded these rates reasonably estimate current market rates. Financial Instruments Measured at Fair Value on a Recurring Basis The Company uses interest rate swaps to add stability to interest expense and to manage, or hedge, its exposure to interest rate movements associated with its variable rate debt or as hedges in anticipation of future debt transactions. The fair values of interest rate swaps are determined using the market standard methodology of netting the discounted future fixed cash receipts (or payments) and the discounted expected variable cash payments (or receipts). The variable cash payments (or receipts) are based on an expectation of future interest rates (forward curves) derived from observable market interest rate curves. To comply with the provisions of ASC Topic 820, management incorporates credit valuation adjustments to appropriately reflect both its nonperformance risk and the respective counterparty’s nonperformance risk in the fair value measurements. In adjusting the fair value of the derivative contracts for the effect of nonperformance risk, the Company has considered the impact of netting and any applicable credit enhancements, such as collateral postings, thresholds, mutual puts and guarantees. Based on guidance issued by the FASB, the Company made an accounting policy election to measure the credit risk of its derivative financial instruments that are subject to master netting agreements on a net basis by counterparty portfolio. As of December 31, 2019, the Company had four outstanding interest rate derivatives with a total notional balance of $300.0 million that were designated as cash flow hedges of interest rate risk. The fair value of interest rate derivative contracts designated as hedging instruments recorded in “Other assets” in the accompanying Consolidated Balance Sheets was $0.1 million and $3.7 million as of December 31, 2019 and December 31, 2018, respectively. The fair value of interest rate derivative contract liabilities recorded in “Accrued expenses and other liabilities” in the accompanying Consolidated Balance Sheets was $5.3 million as of December 31, 2018. There were no interest rate derivative contract liabilities recorded as of December 31, 2019. The Company has recognized a derivative asset related to the redemption feature embedded in the MAA Series I preferred stock. The derivative asset is valued using widely accepted valuation techniques, including a discounted cash flow analysis in which the perpetual value of the preferred shares is compared to the value of the preferred shares assuming the call option is exercised, with the value of the bifurcated call option as the difference between the two values. The analysis reflects the contractual terms of the redeemable preferred shares, which are redeemable at the Company's option beginning on October 1, 2026 and at the redemption price of $50 per share (see Note 8 ). The Co mpany uses various inputs in the anlaysis , including trading data available on the preferred shares, coupon yields on preferred stock issuances from REITs with similar credit ratings as MAA and treasury rates to determine the fair value of the bifurcated call option. The redemption feature embedded in the MAA Series I preferred stock is reported as a derivative asset in “Other assets” in the accompanying Consolidated Balance Sheets and is adjusted to its fair value at each reporting date, with a corresponding non-cash adjustment to “Other non-operating income” in the accompanying Consolidated Statements of Operations. As a result of adjustments of non-cash income recorded to reflect the change in fair value of the derivative asset during the year ended December 31, 2019, the fair value of the embedded derivative asset increased to $36.5 The Company has determined the majority of the inputs used to value its outstanding debt and derivatives, including its embedded derivative, fall within Level 2 of the fair value hierarchy, and as a result, the fair value valuation of its debt and all of its derivatives held as of December 31, 2019 and December 31, 2018 were classified as Level 2 in the fair value hierarchy. The Company’s derivative financial instruments and their related gains and losses are reported in “Net change in operating accounts and other operating activities” in the accompanying Consolidated Statements of Cash Flows. Cash Flow Hedges of Interest Rate Risk The changes in the fair value of derivatives designated and that qualify as cash flow hedges is recorded in “Accumulated other comprehensive loss” and is subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings. As long as a hedging instrument is designated and the results of the effectiveness testing support that the instrument qualifies for hedge accounting treatment, there is no periodic measurement or recognition of ineffectiveness. Rather, the full impact of hedge gains and losses will be recognized in the period in which hedged transactions impact earnings, regardless of whether or not economic mismatches exist in the hedging relationship. Amounts reported in “Accumulated other comprehensive loss” related to derivatives designated as qualifying cash flow hedges will be reclassified to interest expense as interest payments are made on the Company's variable rate or fixed rate debt. During the next twelve months, the Company estimates that an additional $1.1 million Tabular Disclosure of the Effect of Derivative Instruments on the Statements of Operations The tables below present the effect of the Company's derivative financial instruments on the Consolidated Statements of Operations for the years ended December 31, 2019, 2018 and 2017, respectively (dollars in thousands): Derivatives in Cash Flow Hedging Relationships (Loss) Gain Recognized in OCI on Derivative Location of Gain (Loss) Reclassified Gain (Loss) Reclassified from Accumulated OCL into Interest Expense (1) For the Year ended December 31, 2019 2018 2017 from Accumulated OCL into Income 2019 2018 2017 Interest rate contracts $ (11,676 ) $ (751 ) $ 319 Interest expense $ 1,747 $ 1,938 $ (730 ) (1) Derivatives Not Designated as Hedging Instruments Location of Gain (Loss) Recognized in Gain (Loss) Recognized in Earnings on Derivative For the year ended December 31, Income on Derivative 2019 2018 2017 Preferred stock embedded derivative Other non-operating income $ 17,886 $ (2,576 ) $ 8,807 Credit-Risk-Related Contingent Features Certain of the Company's derivative contracts contain a provision where the Company could be declared in default on its derivative obligations if repayment of the underlying indebtedness is accelerated by the lender due to the Company's default on the indebtedness. As of December 31, 2019, the Company had not breached the provisions of these agreements. If the provisions had been breached, the Company could have been required to settle its obligations under the agreements, although there was no termination value liability as of December 31, 2019.

Income Taxes [Abstract]
Income Tax Disclosure	7 . Income Taxes Due to the structure of MAA as a REIT and the nature of the operations of its operating properties, no provision for federal income taxes has been made at the MAA level. In addition, as MAALP is structured as a limited partnership, and its partners recognize their proportionate share of income or loss in their tax returns, no provision for federal income taxes has been made at the MAALP level. Historically, the Company has incurred certain state and local income, excise and franchise taxes. Taxable REIT Subsidiaries A TRS is an entity that is subject to federal, state and any applicable local corporate income tax without the benefit of the dividends paid deduction applicable to REITs. The Company’s TRS did not generate any material taxable income or income tax expense for the years ended December 31, 2019, 2018 and 2017. The Company’s TRS generally provide the Company with third party services (property management services to a real estate joint venture and other services) for which the Company reimburses its TRS. In addition, one of the Company’s TRS has an investment in a limited partnership that generates investment income and losses. All intercompany transactions are eliminated in the accompanying consolidated financial statements. For the years ended December 31, 2019, 2018 and 2017, the reconciliation of income tax attributable to continuing operations for the Company’s TRS computed at the U.S. statutory rate to the income tax provision was as follows (in thousands): 2019 2018 2017 Tax expense at U.S. statutory rates on the Company's TRS income subject to tax $ 1,026 $ 115 $ 2,177 Valuation allowance — 127 (2,177 ) TRS income tax provision $ 1,026 $ 242 $ — Income tax expense primarily relates to the Texas-based margin tax for all Texas apartment communities in addition to the Company’s TRS income tax provision discussed above. Income tax expense for the Company for the years ended December 31, 2019, 2018 and 2017 was $3.7 million, $2.6 million and $2.6 million, respectively, and is presented in “Income tax expense” in the accompanying Consolidated Statements of Operations. The Company’s TRS deferred tax asset and liability balances as of December 31, 2019 and 2018 were immaterial. The TRS had no reserve for uncertain tax positions for the years ended December 31, 2019 and 2018, and management does not believe there will be any material changes in the TRS unrecognized tax positions over the next 12 months. If necessary, the TRS accrues interest and penalties on unrecognized tax benefits as a component of income tax expense. NOL Carryforwards As of December 31, 2019 and 2018, the Company held federal NOL carryforwards of $70.8 million and $71.5 million, respectively, for income tax purposes that expire in years 2019 to 2033. Utilization of any NOL carryforwards is subject to an annual limitation due to ownership change limitations provided by Section 382 of the Code and similar state provisions. The annual limitations may result in the expiration of NOL carryforwards before utilization. The Company may use these NOLs to offset all or a portion of the taxable income generated at the REIT level. Tax years 2016 through 2019 are subject to examination by the Internal Revenue Service. No tax examination is currently in process. Taxable Composition of Distributions For income tax purposes, dividends paid to holders of common stock primarily consist of ordinary income, return of capital, capital gains, qualified dividends and un-recaptured Section 1250 gains, or a combination thereof. For the years ended December 31, 2019, 2018 and 2017, dividends per share held for the entire year were estimated to be taxable as follows: 2019 2018 2017 Amount Percentage Amount Percentage Amount Percentage Ordinary income $ 3.51 91.4 % $ 3.66 99.3 % $ 2.79 80.2 % Capital gain 0.21 5.5 % 0.02 0.6 % 0.31 8.9 % Un-recaptured Section 1250 gain 0.12 3.1 % 0.01 0.1 % 0.38 10.9 % $ 3.84 100 % $ 3.69 100 % $ 3.48 100 % The Company designated the per share amounts above as capital gain dividends in accordance with the requirements of the Code. The difference between net income available to common shareholders for financial reporting purposes and taxable income before dividend deductions relates primarily to temporary differences such as depreciation and amortization and taxable gains on sold properties. U.S. Tax Reform In December 2017, the Tax Cuts and Jobs Act, or the Act, was enacted in the United States, requiring companies to account in 2017 for the current and future effects of the legislative changes. As REITs are pass-through entities for the purpose of U.S. federal taxation, the legislative changes created by the Act were largely not applicable to the Company. Generally, the effects to REITs resulting from the Act included a reduction in the TRS federal statutory tax rate to 21% and a one-time inclusion in REIT taxable income of foreign subsidiary earnings. As noted above, the Company's TRS recognized no material taxable income in 2019, 2018 and 2017, and the Company has no foreign subsidiaries. Management has concluded there was no material effect to the Company’s consolidated financial statements from either a tax or financial statement perspective as a result of the Act.

As of December 31, 2018, 113,844,267 shares of common stock of MAA and 4,111,301 OP Units (excluding the OP Units held by MAA) were issued and outstanding, representing a total of 117,955,568 common shares and units. Preferred Stock As of December 31, 2019, MAA had one outstanding series of cumulative redeemable preferred stock which has the following characteristics: Description Outstanding Shares Liquidation Preference (1) Optional Redemption Date Redemption Price (2) Stated Dividend Yield Approximate Dividend Rate Series I 867,846 $ 50.00 10/1/2026 $ 50.00 8.50% $ 4.25 (1) The total liquidation preference for the outstanding preferred stock is $43.4 million. (2) The redemption price is the price at which the preferred stock is redeemable, at MAA's option, for cash. See Note 6 for details of the valuation of the derivative asset related to the redemption feature embedded in the MAA Series I preferred stock. Direct Stock Purchase and Distribution Reinvestment Plan MAA has a Dividend and Distribution Reinvestment and Share Purchase Plan, or DRSPP, pursuant to which MAA’s common shareholders have the ability to reinvest all or part of their distributions from MAA into shares of MAA’s common stock and holders of Class A OP Units have the ability to reinvest all or part of their distributions from the Operating Partnership into MAA’s common stock. The DRSPP also provides the opportunity to make optional cash investments in MAA's common stock of at least $250, but not more than $5,000 in any given month, free of brokerage commissions and charges. MAA, in its absolute discretion, may grant waivers to allow for optional cash payments in excess of $5,000. To fulfill its obligations under the DRSPP, MAA may either issue additional shares of common stock or repurchase common stock in the open market. MAA currently has registered with the SEC the offer and sale of up to 1,940,500 shares of common stock pursuant to the DRSPP. MAA may elect to sell shares under the DRSPP at up to a 5% discount. Shares of MAA's common stock totaling 16,219 in 2019, 9,721 in 2018, and 9,568 in 2017 were acquired by participants under the DRSPP. MAA did not offer a discount for optional cash purchases in 2019, 2018 or 2017. At-the-Market Share Offering Program The Company has entered into separate distribution agreements with each of J.P. Morgan Securities LLC, BMO Capital Markets Corp. and KeyBanc Capital Markets Inc. to establish an at-the-market share offering program, or ATM program, allowing MAA to sell shares of its common stock from time to time into the existing market at current market prices or through negotiated transactions. Under the ATM program, MAA has the authority to issue up to an aggregate of 4.0 million shares of its common stock, at such times to be determined by MAA. The ATM program currently has a maturity of September 28, 2021. MAA has no obligation to issue shares through the ATM program. During the year ended December 31, 2019, MAA sold 146,301 shares December 31, 2019

Partners Capital Notes [Abstract]
Partners' Capital of MAALP	9 . Partners' Capital of MAALP Common units of limited partnership interests in MAALP are represented by OP Units. As of December 31, 2019, there were 118,313,567 OP Units outstanding, 114,246,393, or 96.6%, of which represent Class B OP Units (common units issued to or held by MAALP's general partner or any of its subsidiaries), which were owned by MAA, MAALP's general partner. The remaining 4,067,174 OP Units were Class A OP Units owned by Class A limited partners. As of December 31, 2018, there were 117,955,568 OP Units outstanding, 113,844,267, or 96.5%, of which were owned by MAA and 4,111,301 of which were owned by the Class A limited partners. MAA, as the sole general partner of MAALP, has full, complete and exclusive discretion to manage and control the business of MAALP subject to the restrictions specifically contained within MAALP's agreement of limited partnership, or the Partnership Agreement. Unless otherwise stated in the Partnership Agreement, this power includes, but is not limited to, acquiring, leasing or disposing of any real property; constructing buildings and making other improvements to properties owned; borrowing money, modifying or extinguishing current borrowings, issuing evidence of indebtedness and securing such indebtedness by mortgage, deed of trust, pledge or other lien on MAALP's assets; and distribution of MAALP's cash or other assets in accordance with the Partnership Agreement. MAA can generally, at its sole discretion, issue and redeem OP Units and determine the consideration to be received or the redemption price to be paid, as applicable. The general partner may delegate these and other powers granted if the general partner remains in supervision of the designee. Under the Partnership Agreement, MAALP may issue Class A OP Units and Class B OP Units. Class A OP Units are any OP Units other than Class B OP Units, while Class B OP Units are those issued to or held by MAALP's general partner or any of its subsidiaries. In general, the limited partners do not have the power to participate in the management or control of MAALP's business except in limited circumstances, including changes in the general partner and protective rights if the general partner acts outside of the provisions provided in the Partnership Agreement. The transferability of Class A OP Units is also limited by the Partnership Agreement. Net income (after allocations to preferred ownership interests) is allocated to the general partner and limited partners based on their respective ownership percentages of MAALP. Issuance or redemption of additional Class A OP Units or Class B OP Units changes the relative ownership percentage of the partners. The issuance of Class B OP Units generally occurs when MAA issues common stock and the proceeds from that issuance are contributed to MAALP in exchange for the issuance to MAA of a number of OP Units equal to the number of shares of common stock issued. Likewise, if MAA repurchases or redeems outstanding shares of common stock, MAALP generally redeems an equal number of Class B OP Units with similar terms held by MAA for a redemption price equal to the purchase price of those shares of common stock. At each reporting period, the allocation between general partner capital and limited partner capital is adjusted to account for the change in the respective percentage ownership of the underlying capital of MAALP. Holders of the Class A OP Units may require MAA to redeem their Class A OP Units, in which case MAA may, at its option, pay the redemption price either in cash (in an amount per Class A OP Unit equal, in general, to the average closing price of MAA's common stock on the NYSE over a specified period prior to the redemption date) or by delivering one share of MAA common stock (subject to adjustment under specified circumstances) for each Class A OP Unit so redeemed. As of December 31, 2019, a total of 4,067,174 As of December 31, 2019, MAALP had one outstanding series of cumulative redeemable preferred units, or the MAALP Series I Preferred Units. The MAALP Series I Preferred Units have the same characteristics as the MAA Series I preferred stock described in Note 8. As of December 31, 2019, 867,846 units of the MAALP Series I Preferred Units were outstanding.

Employee Benefit Plans [Abstract]
EMPLOYEE BENEFIT PLANS	10 . Employee Benefit Plans The following provides details of the employee benefit plans not previously discussed in Note 4. 401(k) Savings Plans MAA's 401(k) Savings Plan, or 401(k) Plan, is a defined contribution plan that satisfies the requirements of Section 401(a) and 401(k) of the Code. MAA's Board of Directors has the discretion to approve matching contributions to the 401(k) Plan. MAA recognized expense from the 401(k) Plan of $3.5 million, $3.2 million and $2.8 million for the years ended December 31, 2019, 2018 and 2017, respectively. Non-Qualified Executive Deferred Compensation Retirement Plan MAA has adopted the MAA Non-Qualified Executive Deferred Compensation Retirement Plan Amended and Restated effective January 1, 2016, or the Deferred Compensation Plan, for certain executive employees. Under the terms of the Deferred Compensation Plan, employees may elect to defer a percentage of their compensation and bonus, and MAA may, but is not obligated to, match a portion of the employees' salary deferral. MAA recognized expense on its match to the Deferred Compensation Plan for the years ended December 31, 2019, 2018 and 2017 of $0.3 million, $0.3 million and $0.2 million, respectively. Non-Qualified Deferred Compensation Plan for Outside Company Directors MAA has adopted the Non-Qualified Deferred Compensation Plan for Outside Company Directors as Amended effective November 20, 2010, or the Directors Deferred Compensation Plan, which allows non-employee directors to defer their director fees by having the fees held by MAA as shares of MAA's common stock. Directors can also choose to have their annual restricted stock grants issued into the Directors Deferred Compensation Plan. Amounts deferred through the Directors Deferred Compensation Plan are distributed to the directors in two annual installments beginning in the first 90 days of the year following the director’s departure from the board. Participating directors may choose to have the amount issued to them in shares of MAA's common stock or paid to them as cash at the market value of MAA's common stock as of the end of the year the director ceases to serve on the board. For the years ended December 31, 2019, 2018 and 2017, directors deferred 10,738 shares, 12,240 shares and 12,293 shares of common stock, respectively, with weighted-average grant date fair values of $117.73, $92.63 and $101.34, respectively, into the Directors Deferred Compensation Plan. The shares of common stock held in the Directors Deferred Compensation Plan are classified outside of permanent equity in redeemable stock with changes in redemption amount recorded immediately to retained earnings because the directors have redemption rights not solely within the control of MAA. Additionally, any shares that become mandatorily redeemable because a departed director has elected to receive a cash payout are recorded as a liability. MAA did not record a liability related to mandatorily redeemable shares for the years ended December 31, 2019, 2018 and 2017. Employee Stock Ownership Plan MAA’s Employee Stock Ownership Plan, or ESOP, is a non-contributory stock bonus plan that satisfies the requirements of Section 401(a) of the Code. On December 31, 2010, the ESOP was frozen by amendment, whereby effective January 1, 2011, no additional employees became eligible for the plan, no additional contributions were made to the ESOP, and all Participants with an account balance under the ESOP became 100% vested. The Company did not contribute to the ESOP during 2019, 2018 or 2017. As of December 31, 2019, there were 131,165

Loss Contingency [Abstract]
Commitments and Contingencies	11 . Commitments and Contingencies Leases The Company's leases include a ground lease expiring in 2074 related to one of its apartment communities and an office lease expiring in 2028 related to its corporate headquarters. Both leases contain stated rent increases that generally compensate for the impact of inflation. The Company also has other commitments related to immaterial office and equipment operating leases. The table below reconciles undiscounted cash flows for each of the first five years and total of the remaining years to the operating lease obligations recorded on the Consolidated Balance Sheets as of December 31, 2019 (in thousands): Operating Leases 2020 $ 2,825 2021 2,854 2022 2,885 2023 2,875 2024 2,853 Thereafter 65,863 Total minimum lease payments 80,155 Net present value adjustments (47,036 ) Operating lease obligations $ 33,119 Legal Proceedings In June 2016, plaintiffs Cathi Cleven and Tara Cleven, on behalf of a purported class of plaintiffs, filed a complaint against MAA and the Operating Partnership in the United States District Court for the Western District of Texas, Austin Division. In January 2017, Areli Arellano and Joe L. Martinez joined the lawsuit as additional plaintiffs. The lawsuit alleges that the Company (but not Post Properties (see the description of the Brown class action lawsuit below)) charged late fees at its Texas properties that violate Section 92.019 of the Texas Property Code, or Section 92.019, which provides that a landlord may not charge a tenant a late fee for failing to pay rent unless, among other things, the fee is a reasonable estimate of uncertain damages to the landlord that are incapable of precise calculation and result from the late payment of rent. The plaintiffs are seeking monetary damages and attorneys' fees and costs. In September 2018, the District Court certified a class proposed by the plaintiffs. Additionally, in September 2018, the District Court denied the Company’s motion for summary judgment and granted the plaintiffs’ motion for partial summary judgment. Because the District Court certified a class prior to granting the plaintiffs’ motion for partial summary judgment, the District Court’s ruling applies to the entire class. In October 2018, the Fifth Circuit Court of Appeals accepted the Company’s petition to review the District Court’s order granting class certification. In September 2019, the Fifth Circuit Court of Appeals heard the Company’s oral arguments. The Company also intends to appeal the District Court’s order granting plaintiff's motion for summary judgment to the Fifth Circuit Court of Appeals if permission to appeal is granted. The Company will continue to vigorously defend the action and pursue such appeals. Management estimates that the Company's maximum exposure in the lawsuit, given the class certification and summary judgment ruling, is $54.6 million , which includes both potential damages and attorneys' fees but excludes any prejudgment interest that may be awarded. In April 2017, plaintiff Nathaniel Brown, on behalf of a purported class of plaintiffs, filed a complaint against the Operating Partnership, as the successor by merger to Post Properties' primary operating partnership, and MAA in the United States District Court for the Western District of Texas, Austin Division. The lawsuit alleges that Post Properties (and, following the Post Properties merger in December 2016, the Operating Partnership) charged late fees at its Texas properties that violate Section 92.019. The plaintiffs are seeking monetary damages and attorney's fees and costs. In September 2018, the District Court certified a class proposed by the plaintiff. Additionally, in September 2018, the District Court denied the Company’s motion for summary judgment and granted the plaintiff’s motion for partial summary judgment. Because the District Court certified a class prior to granting the plaintiff’s motion for partial summary judgment, the District Court’s ruling applies to the entire class. In October 2018, the Fifth Circuit Court of Appeals accepted the Company's petition to review the District Court's order granting class certification. In September 2019, the Fifth Circuit Court of Appeals heard the Company’s oral arguments. The Company is subject to various other legal proceedings and claims that arise in the ordinary course of its business operations. Matters which arise out of allegations of bodily injury, property damage and employment practices are generally covered by insurance. While the resolution of these other matters cannot be predicted with certainty, management does not currently believe that such matters, either individually or in the aggregate, will have a material adverse effect on the Company's financial condition, results of operations or cash flows in the event of a negative outcome. Loss Contingencies The outcomes of claims, disputes and legal proceedings are subject to significant uncertainty. The Company records an accrual for loss contingencies when a loss is probable and the amount of the loss can be reasonably estimated. The Company also accrues an estimate of defense costs expected to be incurred in connection with legal matters. Management reviews these accruals quarterly and makes revisions based on changes in facts and circumstances. When a loss contingency is not both probable and reasonably estimable, management does not accrue the loss. However, if the loss (or an additional loss in excess of the accrual) is at least a reasonable possibility and material, then management discloses a reasonable estimate of the possible loss, or range of loss, if such reasonable estimate can be made. If the Company cannot make a reasonable estimate of the possible loss, or range of loss, then a statement to that effect is disclosed. The assessment of whether a loss is probable or a reasonable possibility, and whether the loss or range of loss is reasonably estimable, often involves a series of complex judgments about future events. Among the factors considered in this assessment, are the nature of existing legal proceedings and claims, the asserted or possible damages or loss contingency (if reasonably estimable), the progress of the matter, existing law and precedent, the opinions or views of legal counsel and other advisers, management's experience in similar matters, the facts available to management at the time of assessment, and how the Company intends to respond, or has responded, to the proceeding or claim. Management's assessment of these factors may change over time as individual proceedings or claims progress. For matters where management is not currently able to reasonably estimate a range of reasonably possible loss, the factors that have contributed to this determination include the following: (i) the damages sought are indeterminate; (ii) the proceedings are in the early stages; (iii) the matters involve novel or unsettled legal theories or a large or uncertain number of actual or potential cases or parties; and/or (iv) discussions with the parties in matters that are ultimately expected to be resolved through negotiation and settlement have not reached the point where management believes a reasonable estimate of loss, or range of loss, can be made. The Company believes that there is considerable uncertainty regarding the timing or ultimate resolution of such matters, including a possible eventual loss or business impact, if any. As of December 31, 2019 and December 31, 2018, the Company's accrual for loss contingencies relating to unresolved legal matters was $8.6 million and $8.7 million in the aggregate, respectively. The loss contingencies are presented in “Accrued expenses and other liabilities ” in the accompanying Consolidated Balance Sheets .

Related Party Transactions [Abstract]
Related Party Transactions	1 2 . Related Party Transactions The Company holds investments in unconsolidated affiliates accounted for under the equity method of accounting. All significant intercompany transactions were eliminated in the accompanying consolidated financial statements. The cash management of the Company is managed by the Operating Partnership. In general, cash receipts are remitted to the Operating Partnership and all cash disbursements are funded by the Operating Partnership. As a result of these transactions, the Operating Partnership had a payable to MAA, its general partner, of $19,000 as of December 31, 2019 and December 31, 2018, respectively. The Partnership Agreement does not require the due to/due from balance to be settled in cash until liquidation of the Operating Partnership, and therefore, there is no regular settlement schedule for such amounts.

Segment Information

Segment Information	12 Months Ended

Notes To Financial Statements [Abstract]
Segment Information	13 . Segment Information As of December 31, 2019, the Company owned and operated 299 multifamily apartment communities in 16 different states from which it derived all significant sources of earnings and operating cash flows. The Company views each consolidated apartment community as an operating segment. The Company's chief operating decision maker, which is the Company’s Chief Executive Officer, evaluates performance and determines resource allocations of each of the apartment communities on a Same Store and Non-Same Store and Other basis, as well as an individual apartment community basis. This is consistent with the aggregation criteria under GAAP as each of the apartment communities generally has similar economic characteristics, facilities, services, and tenants. The following reflects the two reportable segments for the Company: • Same Store communities are communities that the Company has owned and have been stabilized for at least a full 12 months. • Non-Same Store and Other includes recent acquisitions, communities in development or lease-up, communities that have been identified for disposition and communities that have incurred a significant casualty loss. Also included in Non-Same Store and Other are non-multifamily activities. On the first day of each calendar year, the Company determines the composition of its Same Store and Non-Same Store and Other reportable segments for that year as well as adjusts the previous year, which allows the Company to evaluate full period-over-period operating comparisons. Properties in development or lease-up are added to the Same Store portfolio on the first day of the calendar year after a community has been owned and stabilized for at least a full 12 months. Communities are considered stabilized after achieving 90% occupancy for 90 days. Communities that have been identified for disposition are excluded from the Same Store portfolio. The chief operating decision maker utilizes net operating income, or NOI, in evaluating the performance of its operating segments. Total NOI represents total property revenues less total property operating expenses, excluding depreciation and amortization, for all properties held during the period regardless of their status as held for sale. Management believes that NOI is a helpful tool in evaluating the operating performance of the segments because it measures the core operations of property performance by excluding corporate level expenses and other items not directly related to property operating performance. Revenues and NOI for each reportable segment for the years ended December 31, 2019, 2018 and 2017 were as follows (in thousands): 2019 2018 2017 Revenues: Same Store Rental revenues $ 1,505,775 $ 1,364,744 $ 1,313,836 Reimbursable property revenues (1) — 91,020 88,774 Other property revenues 12,100 11,696 12,229 Total Same Store revenues 1,517,875 1,467,460 1,414,839 Non-Same Store and Other Rental revenues 121,829 99,281 105,865 Reimbursable property revenues (1) — 3,744 5,282 Other property revenues 1,313 861 3,001 Total Non-Same Store and Other revenues 123,142 103,886 114,148 Total rental and other property revenues $ 1,641,017 $ 1,571,346 $ 1,528,987 Net Operating Income: Same Store NOI $ 956,075 $ 921,240 $ 889,176 Non-Same Store and Other NOI 72,097 55,518 63,080 Total NOI 1,028,172 976,758 952,256 Depreciation and amortization (496,843 ) (489,759 ) (493,708 ) Property management expenses (55,011 ) (47,633 ) (43,588 ) General and administrative expenses (46,121 ) (34,786 ) (40,194 ) Merger and integration expenses — (9,112 ) (19,990 ) Interest expense (179,847 ) (173,594 ) (154,751 ) Gain (loss) on sale of depreciable real estate assets 80,988 (39 ) 127,386 Gain on sale of non-depreciable real estate assets 12,047 4,532 21 Other non-operating income 25,275 5,434 14,353 Income tax expense (3,696 ) (2,611 ) (2,619 ) Income from real estate joint venture 1,654 1,832 1,370 Net income attributable to noncontrolling interests (12,807 ) (8,123 ) (12,157 ) Dividends to MAA Series I preferred shareholders (3,688 ) (3,688 ) (3,688 ) Net income available for MAA common shareholders $ 350,123 $ 219,211 $ 324,691 (1) Assets for each reportable segment as of December 31, 2019 and 2018 were as follows (in thousands): December 31, 2019 December 31, 2018 Assets: Same Store $ 9,661,935 $ 9,921,270 Non-Same Store and Other 1,362,974 1,233,351 Corporate assets 205,541 169,160 Total assets $ 11,230,450 $ 11,323,781

Organization and Summary of Significant Accounting Policies (Policies)	12 Months Ended

Accounting Policies [Abstract]
Basis of Presentation And Principles Of Consolidation	Basis of Presentation and Principles of Consolidation The accompanying consolidated financial statements have been prepared by the Company's management in accordance with United States generally accepted accounting principles, or GAAP, and applicable rules and regulations of the Securities and Exchange Commission, or the SEC. The consolidated financial statements of MAA presented herein include the accounts of MAA, the Operating Partnership and all other subsidiaries in which MAA has a controlling financial interest. MAA owns, directly or indirectly, approximately 80% to 100% of all consolidated subsidiaries, including the Operating Partnership. The consolidated financial statements of MAALP presented herein include the accounts of MAALP and all other subsidiaries in which MAALP has a controlling financial interest. MAALP owns, directly or indirectly, 80% to 100% of all consolidated subsidiaries. In management's opinion, all adjustments necessary for a fair presentation of the consolidated financial statements have been included, and all such adjustments were of a normal recurring nature. All significant intercompany accounts and transactions have been eliminated in consolidation. The Company invests in entities which may qualify as variable interest entities, or VIEs, and MAALP is considered a VIE. A VIE is a legal entity in which the equity investors lack sufficient equity at risk for the entity to finance its activities without additional subordinated financial support or, as a group, the holders of the equity investment at risk lack the power to direct the activities of a legal entity as well as the obligation to absorb its expected losses or the right to receive its expected residual returns. MAALP is classified as a VIE because the limited partners lack substantive kick-out rights and substantive participating rights. The Company consolidates all VIEs for which it is the primary beneficiary and uses the equity method to account for investments that qualify as VIEs but for which it is not the primary beneficiary. In determining whether the Company is the primary beneficiary of a VIE, management considers both qualitative and quantitative factors, including, but not limited to, those activities that most significantly impact the VIE's economic performance and which party controls such activities. The Company uses the equity method of accounting for its investments in entities for which the Company exercises significant influence, but does not have the ability to exercise control. The factors considered in determining whether the Company has the ability to exercise control include ownership of voting interests and participatory rights of investors (see “Investments in Unconsolidated Affiliates” below).
Changes in Presentation	Changes in Presentation In order to simplify the Company's presentation of cash flows from financing activities within the Consolidated Statements of Cash Flows, the Company combined “Repurchase of common stock / units”; “Debt prepayment and extinguishment costs”; “Proceeds from issuances of common shares / units”; and “Exercise of stock / unit options” into one line, “Net change in other financing activities” within the cash flows from financing activities section. No presentation changes were made to the cash flows from operating or investing activities sections of the Consolidated Statements of Cash Flows. Prior year amounts have been changed to conform to the Company's current year presentation. These changes in presentation had no effect on the Company's ending cash, cash equivalents and restricted cash balances and did not impact the classification of cash flows between operating, investing and financing activities.
Noncontrolling Interests	Noncontrolling Interests As of December 31, 2019, the Company had two types of noncontrolling interests with respect to its consolidated subsidiaries, (1) noncontrolling interests related to the common unitholders of its Operating Partnership and (2) noncontrolling interests related to its consolidated real estate entities. The noncontrolling interests relating to the limited partnership interests in the Operating Partnership are owned by the holders of the Class A OP Units. MAA is the sole general partner of the Operating Partnership and holds all of the outstanding Class B OP Units. Net income (after allocations to preferred ownership interests) is allocated to MAA and the noncontrolling interests based on their respective ownership percentages of the Operating Partnership. Issuance of additional Class A OP Units or Class B OP Units changes the ownership percentage of both the noncontrolling interests and MAA. The issuance of Class B OP Units generally occurs when MAA issues common stock and the issuance proceeds are contributed to the Operating Partnership in exchange for Class B OP Units equal to the number of shares of MAA's common stock issued. At each reporting period, the allocation between total MAA shareholders’ equity and noncontrolling interests is adjusted to account for the change in the respective percentage ownership of the underlying equity of the Operating Partnership. MAA’s Board of Directors established economic rights in respect to each Class A OP Unit that were equivalent to the economic rights in respect to each share of MAA common stock. See Note 9 for additional details. The noncontrolling interests relating to the Company’s consolidated real estate entities are owned by private real estate companies that are generally responsible for the development and construction of the apartment communities that are owned through the consolidated real estate entities with a noncontrolling interest. The entities were determined to be VIE’s with the Company designated as the primary beneficiary. As a result, the accounts of the entities are consolidated by the Company. During the year ended December 31, 2019, the Company acquired a partial ownership interest in two consolidated real estate entities and acquired the noncontrolling interest of one consolidated real estate entity for cash proceeds of $ 10.9 million. As of December 31, 2019, the consolidated assets and liabilities of the Company’s consolidated real estate entities with a noncontrolling interest were $ million and $ 3.2 million, respectively. As of December 31, 2018, the consolidated assets and liabilities of the Company’s consolidated real estate entity with a noncontrolling interest were $ 85.7 million and $ 1.3 million, respectively.
Use of Estimates	Use of Estimates Management has made a number of estimates and assumptions relating to the reporting of assets and liabilities, the disclosure of contingent assets and liabilities, and the reported amounts of revenues and expenses to prepare these financial statements and notes in conformity with GAAP. Actual results could differ from those estimates.
Rental Costs	Rental Costs Costs associated with rental activities are expensed as incurred and include advertising expenses, which were $20.8 million, $20.2 million, and $18.8 million for the years ended December 31, 2019, 2018 and 2017, respectively.
Real Estate Assets and Depreciation and Amortization	Real Estate Assets and Depreciation and Amortization Real estate assets are carried at depreciated cost and consist of land, buildings and improvements and other and development and capital improvements in progress (see “Development Costs” below). Repairs and maintenance costs are expensed as incurred, while significant improvements, renovations and recurring capital replacements are capitalized and depreciated over their estimated useful lives. Recurring capital replacements typically include scheduled carpet replacement, new roofs, HVAC units, plumbing, concrete, masonry and other paving, pools and various exterior building improvements. In addition to these costs, the Company also capitalizes salary costs directly identifiable with renovation work. These expenditures extend the useful life of the property and increase the property’s fair market value. The cost of interior painting and blinds are typically expensed as incurred. Depreciation is computed on a straight-line basis over the estimated useful lives of the related assets, which range from five to 40 years. The Consolidated Balance Sheets line “Buildings and improvements and other” includes land improvements and buildings, which have a useful life ranging from eight to 40 years, as well as furniture, fixtures and equipment, which have a useful life of five years.
Development Costs	Development Costs Development projects and the related carrying costs, including interest, property taxes, insurance and allocated direct development salary costs during the construction period, are capitalized and reported in the accompanying Consolidated Balance Sheets as “Development and capital improvements in progress” during the construction period. Interest is capitalized in accordance with accounting standards governing the capitalization of interest. Upon completion and certification for occupancy of individual buildings or floors within a development, amounts representing the completed portion of total estimated development costs for the project are transferred to “Buildings and improvements and other” as real estate held for investment. Capitalization of interest, property taxes, insurance and allocated direct development salary costs cease upon the transfer. The assets are depreciated over their estimated useful lives. Total capitalized costs (including capitalized interest, salaries and real estate taxes) during the years ended December 31, 2019, 2018 and 2017 were $6.5 million, $4.2 million and $11.0 million, respectively. Certain costs associated with the lease-up of development projects, including cost of model units, furnishings and signs, are capitalized and amortized over their respective estimated useful lives. All other costs relating to renting development projects are expensed as incurred.
Acquisition of Real Estate Assets	Acquisition of Real Estate Assets In accordance with Accounting Standards Codification, or ASC, Topic 805, Business Combinations The purchase price of an acquired property is allocated based on the relative fair value of the individual components as a proportion of the total assets acquired. The Company allocates the cost of the tangible assets of an acquired property by valuing the building as if it were vacant, based on management’s determination of the relative fair values of these assets. Management determines the as-if-vacant fair value of a building using methods similar to those used by independent appraisers. These methods include using stabilized net operating income, or NOI, and market specific capitalization and discount rates. In allocating the cost of identified intangible assets of an acquired property, the in-place leases are valued based on current rent rates and time and cost to lease a unit. Management concluded that the residential leases acquired in connection with each of its property acquisitions approximate at-market rates since the residential lease terms generally do not extend beyond one year. For residential leases, the fair value of the in-place leases and resident relationships is amortized over six months, which represents the estimated remaining term of the tenant leases. For retail and commercial leases, the fair value of in-place leases and tenant relationships is amortized over the remaining term of the leases. The net amount of these lease intangibles included in “Other assets” totaled $2.6 million and $3.9 million as of December 31, 2019 and 2018, respectively.
Impairment of Long-lived Assets, including Goodwill	Impairment of Long-lived Assets The Company accounts for long-lived assets in accordance with the provisions of accounting standards for the impairment or disposal of long-lived assets. Management periodically evaluates long-lived assets, including investments in real estate, for indicators that would suggest that the carrying amount of the assets may not be recoverable. The judgments regarding the existence of such indicators are based on factors such as operating performance, market conditions and legal factors. Long-lived assets, such as real estate assets, equipment and purchased intangibles subject to amortization, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to estimated undiscounted future cash flows expected to be generated by the asset. If the carrying amount of an asset exceeds its estimated future cash flows, an impairment charge is recognized for the amount by which the carrying amount of the asset exceeds the fair value of the asset. Assets to be disposed of are separately presented in the Consolidated Balance Sheets and reported at the lower of the carrying amount or fair value less costs to sell, and are no longer depreciated. The assets and liabilities of a disposed group or a property classified as held for sale are presented separately in the appropriate asset and liability sections of the Consolidated Balance Sheets.
Undeveloped Land	Undeveloped Land Undeveloped land includes sites intended for future multifamily developments, sites for future commercial development and sites intended for residential use, which are carried at the lower of cost or fair value in accordance with GAAP. Any costs incurred prior to commencement of pre-development activities are expensed as incurred.
Investments in Unconsolidated Affiliates	Investments in Unconsolidated Affiliates The Company uses the equity method to account for its investments in a real estate joint venture and a limited partnership that both qualify as a VIE. Management determined the Company is not the primary beneficiary in either investment but does have the ability to exert significant influence over the operations and financial policies of the real estate joint venture and considers its investment in the limited partnership to be more than minor. As of December 31, 2019 and 2018, the Company's investment in the real estate joint venture was $43.7 million and $44.2 million, respectively. As of December 31, 2019 and 2018, the Company's investment in the limited partnership was $13.1 million and $3.8 million, respectively, and is included in “Other assets” in the accompanying Consolidated Balance Sheets. As of December 31, 2019, the Company was committed until September 2022 to make additional capital contributions totaling $8.2 million if and when called by the general partner of the limited partnership.
Cash and Cash Equivalents	Cash and Cash Equivalents Investments in money market accounts and certificates of deposit with original maturities of three months or less are considered to be cash equivalents.
Restricted Cash	Restricted Cash Restricted cash consists of security deposits required to be held separately, escrow deposits held by lenders for property taxes, insurance, debt service and replacement reserves, and exchanges under Section 1031(b) of the Internal Revenue Code of 1986, as amended, or the Code. Section 1031(b) exchanges are presented within cash, cash equivalents and restricted cash reported in the Consolidated Statements of Cash Flows.
Other Assets	Other Assets Other assets consist primarily of receivables and deposits from residents, the value of derivative contracts, right-of-use lease assets, investment in a limited partnership, deferred rental concessions, deferred financing costs relating to a revolving credit facility and other prepaid expenses. Also included in other assets are the fair market value of in-place leases and resident relationships, net of accumulated amortization.
Accrued Expenses and Other Liabilities	Accrued Expenses and Other Liabilities Accrued expenses consist of accrued dividends payable, accrued real estate taxes, accrued interest payable, accrued loss contingencies (see Note 11), accounts payable, right-of-use lease liabilities, security deposits not related to restricted cash, other accrued expenses, and unearned income. Significant accruals include accrued dividends payable of $118.3 million and $113.2 million as of December 31, 2019 and 2018, respectively; accrued real estate taxes of $131.9 million loss contingencies of $ 8.6 million and $ 8.7 million as of December 31, 2019 and 2018 , respectively; security deposits of $ 19.4 million and $ 18.7 million as of December 31, 2019 and 2018 , respectively; and accrued interest payable of $ 21.4 million and $ million as of December 31, 2019 and 2018 , respectively.
Income Taxes	Income Taxes MAA has elected to be taxed as a REIT under the Code and intends to continue to operate in such a manner. The current and continuing qualification as a REIT depends on MAA's ability to meet the various requirements imposed by the Code, which are related to organizational structure, distribution levels, diversity of stock ownership and certain requirements with respect to the nature and diversity of MAA’s assets and sources of MAA’s gross income. As long as MAA qualifies for taxation as a REIT, it will generally not be subject to United States federal corporate income tax on its taxable income that is currently distributed to shareholders. This treatment substantially eliminates the “double taxation” (i.e., income taxation at both the corporate and shareholder levels) that generally results from an investment in a corporation. Even if MAA qualifies as a REIT, MAA may be subject to United States federal income and excise taxes in certain situations, such as if MAA fails to distribute timely all of its taxable income with respect to a taxable year. MAA also will be required to pay a 100% tax on any net income on non-arm’s length transactions between MAA and one of its taxable REIT subsidiaries, or TRS. Furthermore, MAA and its shareholders may be subject to state or local taxation in various state or local jurisdictions, including those in which MAA transacts business or its shareholders reside, and the applicable state and local tax laws may not conform to the United States federal income tax treatment. Any taxes imposed on MAA would reduce its operating cash flows and net income. The Company has elected TRS status for certain of its corporate subsidiaries. As a result, the TRS incur both federal and state income taxes on any taxable income after consideration of any net operating losses. The TRS use the liability method of accounting for income taxes. Deferred income tax assets and liabilities are recognized for future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities from a change in tax rate is recognized in earnings in the period of the enactment date. A valuation allowance is provided when it is more likely than not that all or some portion of the deferred tax assets will not be realized. The Company recognizes liabilities for uncertain income tax positions based on a two-step process. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates that it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation processes, if any. The second step requires the Company to estimate and measure the tax benefit as the largest amount that is more likely than not to be realized upon ultimate settlement. See Note 7 for additional disclosures regarding income taxes.
Fair value of derivative financial instruments	Fair Value Measurements The Company applies the guidance in ASC Topic 820, Fair Value Measurements and Disclosures Level 1 - Quoted prices in active markets for identical assets or liabilities that are accessible at the measurement date. Level 2 - Inputs other than quoted prices that are observable for the asset or liability, either directly or indirectly. Level 3 - Unobservable inputs for the assets or liability.
Leases	Leases In 2016, the Financial Accounting Standards Board, or FASB, issued Accounting Standard Update, or ASU, 2016-02, Leases Comparative periods presented in this Annual Report on Form 10-K continue to apply guidance in ASC Topic 840, Leases, revenues as the Company's residential, retail and commercial leases, where it is the lessor, will continue to be accounted for as operating leases. Management has elected available practical expedients that provide lessors an option not to separate lease and non-lease components when certain criteria are met, and instead, allow for those components to be accounted for as a single lease component. B eginning with the effective date of the adoption of the new standard, rental revenues and non-lease reimbursable property revenues meet the criteria to be aggregated into a single lease component and are reported in the line item, “ Rental revenues ” , as presented in the disaggregation of the Company's revenues in Note 13. The Company is the lessee under certain ground, office, equipment and other operating leases. Based on its election of the package of practical expedients provided in ASU 2016-02, the Company did not reassess the classification of existing leases with its adoption of ASC Topic 842. The Company’s existing leases as of January 1, 2019 have continued to be accounted for as operating leases; however, if contracts are modified subsequent to the adoption of the new standard, the Company is required to reassess the contracts using guidance provided under ASC Topic 842. The Company recognized total right-of-use assets of $54.3 million within “Other assets” and related lease obligations of $33.6 million within “Accrued expenses and other liabilities” in its Consolidated Balance Sheets for leases in effect as of January 1, 2019. As of December 31, 2019, right-of-use assets and the related lease obligations totaled $53.8 million and $33.1 million, respectively. As most leases do not provide a readily determinable implicit rate to discount future minimum lease payments to present value, management estimated the Company's incremental borrowing rate based on information available as of the date of adoption and based on the remaining lease terms as of the date of initial application. Operating leases recognized upon adoption had a weighted-average remaining lease term of approximately 33 years and management estimated a weighted-average discount rate of approximately 4.4%. Operating leases as of December 31, 2019 have a weighted-average remaining lease term of approximately 32 years and a weighted-average discount rate of approximately 4.4%. Lease expense recognized for the years ended December 31, 2019, 2018 and 2017 was immaterial to the Company and was recognized in a similar manner for all years presented. Cash paid for amounts included in the measurement of operating lease liabilities during the year ended December 31, 2019 was also immaterial.
Revenue Recognition	Revenue Recognition The Company primarily leases multifamily residential apartments under operating leases generally due on a monthly basis with terms of approximately one year or less, which are recorded as operating leases. Rental revenues are recognized in accordance with ASC Topic 842 using a method that represents a straight-line basis over the term of the lease. In addition, in circumstances where a lease incentive is provided to tenants, the incentive is recognized as a reduction of rental revenues on a straight-line basis over the reasonably assured lease term. Rental revenues represent approximately 93% of the Company's total revenues and include gross rents charged less adjustments for concessions and bad debt. Approximately 6% of the Company's total revenues represents reimbursable property revenues from its tenants for utility reimbursements, which are generally recognized and due on a monthly basis as tenants obtain control of the service over the term of the lease. The remaining 1% of the Company's total revenues represents other non-lease revenues primarily driven by nonrefundable fees and commissions. With the adoption of ASC Topic 842, rental revenues and non-lease reimbursable property revenues meet the criteria to be aggregated into a single lease component and are reported on a combined basis, while non-lease reimbursable property revenues recognized prior to January 1, 2019 is reported as non-lease revenues and recognized in accordance with ASC Topic 606, Revenue Recognition.
