Description of Business [Abstract]
Description Of Business	1. Description of Business Business. Formed on May 25, 1993, Camden Property Trust, a Texas real estate investment trust (“REIT”), and all consolidated subsidiaries are primarily engaged in the ownership, management, development, redevelopment, acquisition, and construction of multifamily apartment communities. Our multifamily apartment communities are referred to as “communities,” “multifamily communities,” “properties,” or “multifamily properties” in the following discussion. As of December 31, 2018 , we owned interests in, operated, or were developing 167 multifamily properties comprised of 56,858 apartment homes across the United States. Of the 167 properties, six properties were under construction, and will consist of a total of 1,698 apartment homes when completed. We also own land holdings which we may develop into multifamily communities in the future.

Accounting Policies [Abstract]
Summary Of Significant Accounting Policies And Recent Accounting Pronouncements	2. Summary of Significant Accounting Policies and Recent Accounting Pronouncements Principles of Consolidation . Our consolidated financial statements include our accounts and the accounts of other subsidiaries and joint ventures (including partnerships and limited liability companies) over which we have control. All intercompany transactions, balances, and profits have been eliminated in consolidation. Investments acquired or created are evaluated based on the accounting guidance relating to variable interest entities (“VIEs”), which requires the consolidation of VIEs in which we are considered to be the primary beneficiary. If the investment is determined not to be a VIE, then the investment is evaluated for consolidation primarily using a voting interest model. In determining if we have a controlling financial interest, we consider factors such as ownership interests, authority to make decisions, kick-out rights and participating rights. As of December 31, 2018 , two of our consolidated operating partnerships are VIEs. We are considered the primary beneficiary of both consolidated operating partnerships and therefore consolidate these operating partnerships. We hold the sole 1% general partnership interest in each of these consolidated operating partnership VIEs. During the year ended December 31, 2018 , certain unit holders of one of these consolidated operating partnerships redeemed their operating partnership units in exchange for cash consideration of approximately $14.4 million , and as of December 31, 2018 , we held approximately 95% of the outstanding common limited partnership units. We held approximately 92% of the outstanding common limited partnership units of the other consolidated operating partnership as of December 31, 2018 . Acquisitions of Real Estate . Upon acquisition of real estate, we determine the fair value of tangible and intangible assets, which includes land, buildings (as-if-vacant), furniture and fixtures, the value of in-place leases, including above and below market leases, and acquired liabilities. In estimating these values, we apply methods similar to those used by independent appraisers of income-producing property. Estimates of fair value of acquired debt are based upon interest rates available for the issuance of debt with similar terms and remaining maturities. Depreciation is computed on a straight-line basis over the remaining useful lives of the related tangible assets. The value of in-place leases and above or below market leases is amortized over the estimated average remaining life of leases in place at the time of acquisition; the net carrying value of in-place leases are included in other assets, net and the net carrying value of above or below market leases are included in other liabilities, net in our condensed consolidated balance sheets. During the year ended December 31, 2018 and 2017 , we recognized amortization expense of approximately $9.4 million and $1.3 million , respectively, related to in-place leases. We recognized revenue of approximately $0.2 million related to net below market leases for the year ended December 31, 2018 , and did not recognize any revenue related to net below market leases for the year ended December 31, 2017 . During the year ended December 31, 2018 , the weighted average amortization periods for in-place and net below market leases were approximately seven months and five months , respectively. During the year ended December 31, 2017 , the weighted average amortization period for in-place leases was approximately six months. We did not recognize any revenue or amortization expense related to below market or in-place leases for the year ended December 31, 2016. Asset Impairment . Long-lived assets are reviewed for impairment annually or whenever events or changes in circumstances indicate the carrying amount of an asset may not be recoverable. Impairment may exist if estimated future undiscounted cash flows associated with long-lived assets are not sufficient to recover the carrying value of such assets. We consider projected future undiscounted cash flows, trends, strategic decisions regarding future development plans, and other factors in our assessment of whether impairment conditions exist. While we believe our estimates of future cash flows are reasonable, different assumptions regarding a number of factors, including market rents, economic conditions, and occupancies, could significantly affect these estimates. In estimating fair value, management uses appraisals, management estimates, and discounted cash flow calculations which utilize inputs from a marketplace participant’s perspective. When impairment exists, the long-lived asset is adjusted to its fair value. In addition, we evaluate our equity investments in joint ventures and if we believe there is an other than temporary decline in market value of our investment below our carrying value, we will record an impairment charge. We did not record any impairment charges for the years ended December 31, 2018 , 2017 , or 2016 . The value of our properties under development depends on market conditions, including estimates of the project start date as well as estimates of demand for multifamily communities. We have reviewed market trends and other marketplace information and have incorporated this information as well as our current outlook into the assumptions we use in our impairment analyses. Due to the judgment and assumptions applied in the impairment analyses, it is possible actual results could differ substantially from those estimated. We believe the carrying value of our operating real estate assets, properties under development, and land is currently recoverable. However, if market conditions deteriorate or if changes in our development strategy significantly affect any key assumptions used in our fair value estimates, we may need to take material charges in future periods for impairments related to existing assets. Any such material non-cash charges could have an adverse effect on our consolidated financial position and results of operations. Cash and Cash Equivalents . All cash and investments in money market accounts and other highly liquid securities with a maturity of three months or less at the date of purchase are considered to be cash and cash equivalents. We maintain the majority of our cash and cash equivalents at major financial institutions in the United States and deposits with these financial institutions may exceed the amount of insurance provided on such deposits; however, we regularly monitor the financial stability of these financial institutions and believe we are not currently exposed to any significant default risk with respect to these deposits. Short-term Investments . Our short-term investments consisted of certificates of deposit which have original maturities of more than three months but less than one year. Cost Capitalization . Real estate assets are carried at cost plus capitalized carrying charges. Carrying charges are primarily interest and real estate taxes which are capitalized as part of properties under development. Capitalized interest is generally based on the weighted average interest rate of our unsecured debt. Expenditures directly related to the development and improvement of real estate assets are capitalized at cost as land and buildings and improvements. Indirect development costs, including salaries and benefits and other related costs directly attributable to the development of properties, are also capitalized. We begin capitalizing development, construction, and carrying costs when the development of the future real estate asset is probable and activities necessary to prepare the underlying real estate for its intended use have been initiated. All construction and certain carrying costs are capitalized and reported in the balance sheet as properties under development until the apartment homes are substantially completed. As apartment homes within development properties are completed, the total capitalized development cost of each apartment home is transferred from properties under development including land to buildings and improvements. As discussed above, carrying charges are principally interest and real estate taxes capitalized as part of properties under development. Capitalized interest was approximately $13.6 million , $15.2 million , and $18.2 million for the years ended December 31, 2018 , 2017 , and 2016 , respectively. Capitalized real estate taxes were approximately $2.2 million , $2.4 million , and $4.5 million for the years ended December 31, 2018 , 2017 , and 2016 , respectively. Where possible, we stage our construction to allow leasing and occupancy during the construction period, which we believe minimizes the duration of the lease-up period following completion of construction. Our accounting policy related to properties in the development and leasing phase is to expense all operating expenses associated with completed apartment homes. We capitalize renovation and improvement costs we believe extend the economic lives of depreciable property. Capital expenditures subsequent to initial construction are capitalized and depreciated over their estimated useful lives. We also incur expenditures related to renovation and construction of office space we lease and we capitalize these leasehold improvements as furniture, fixtures, equipment and other. We depreciate these costs using the straight-line method over the shorter of the lease term or the useful life of the improvement. Depreciation and amortization is computed over the expected useful lives of depreciable property on a straight-line basis with lives generally as follows: Estimated Useful Life Buildings and improvements 5-35 years Furniture, fixtures, equipment and other 3-20 years Intangible assets/liabilities (in-place leases and below market leases) underlying lease term Derivative Financial Instruments. Derivative financial instruments are recorded in the consolidated balance sheets at fair value and we do not apply master netting for financial reporting purposes. Accounting for changes in the fair value of derivatives depends on the intended use of the derivative, whether we have elected to designate a derivative in a hedging relationship and apply hedge accounting, and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. Derivatives designated and qualifying as a hedge of the exposure to variability in expected future cash flows or other types of forecasted transactions are cash flow hedges. Hedge accounting generally provides for the matching of the timing of gain or loss recognition on the hedging instrument with the recognition of the changes attributable to the earnings effect of the hedged transactions. We may enter into derivative contracts which are intended to economically hedge certain of our risks, for which hedge accounting does not apply or we elect not to apply hedge accounting. Discontinued Operations . A property is classified as a discontinued operation when the disposal represents a strategic shift, such as disposal of a major line of business, a major geographical area or a major equity investment. The results of operations for properties sold during the period or classified as held for sale at the end of the period, and meeting the above criteria of discontinued operations, are classified as discontinued operations for all periods presented. The property-specific components of earnings classified as discontinued operations include separately identifiable property-specific revenues, expenses, depreciation, and interest expense, if any. The gain or loss resulting from the eventual disposal of the held for sale properties meeting the criteria of discontinued operations is also classified within discontinued operations. Real estate assets held for sale are measured at the lower of carrying amount or fair value less costs to sell and are presented separately in the accompanying consolidated balance sheets. Subsequent to classification of a property as held for sale, no further depreciation is recorded. Consolidated operating properties sold or classified as held for sale, which do not meet the above criteria of discontinued operations are not included in discontinued operations and the related gains and losses are included in continuing operations. Properties sold by our unconsolidated entities which do not meet the above criteria of discontinued operations are not included in discontinued operations and related gains or losses are reported as a component of equity in income of joint ventures. Gains on sale of real estate are recognized using the full accrual or partial sale methods, as applicable, in accordance with accounting principles generally accepted in the United States of America ("GAAP"), provided various criteria relating to the terms of sale and any subsequent involvement with the real estate sold are satisfied. See Note 8, "Acquisitions, Dispositions, and Discontinued Operations," for discussion of discontinued operations for the year ended December 31, 2016. There were no discontinued operations for the years ended 2018 or 2017 . Fair Value . For financial assets and liabilities recorded at fair value on a recurring or non-recurring basis, fair value is the price we would receive to sell an asset, or pay to transfer a liability, in an orderly transaction with a market participant at the measurement date. In the absence of such data, fair value is estimated using internal information consistent with what market participants would use in a hypothetical transaction. In determining fair value, observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect our market assumptions; preference is given to observable inputs. These two types of inputs create the following fair value hierarchy: • Level 1: Quoted prices for identical instruments in active markets. • Level 2: Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations whose inputs are observable or whose significant value drivers are observable. • Level 3: Significant inputs to the valuation model are unobservable. Recurring Fair Value Measurements. The following describes the valuation methodologies we use to measure different financial instruments at fair value on a recurring basis: Deferred Compensation Plan Investments. The estimated fair values of investment securities classified as deferred compensation plan investments are based on quoted market prices utilizing public information for the same transactions. Our deferred compensation plan investments are recorded in other assets in our consolidated balance sheets. The inputs associated with the valuation of our recurring deferred compensation plan investments are included in Level 1 of the fair value hierarchy. Derivative Financial Instruments. The estimated fair values of derivative financial instruments are valued using widely accepted valuation techniques including discounted cash flow analysis on the expected cash flows of each derivative. This analysis reflects the contractual terms of the derivatives, including the period to maturity, and uses observable market-based inputs, including interest rate curves and volatility. The fair values of interest rate swaps and caps are estimated using the market-standard methodology of netting the discounted fixed cash payments and the discounted expected variable cash receipts. The variable cash receipts are based on an expectation of interest rates (forward curves) derived from observable market interest rate curves. In addition, credit valuation adjustments, which consider the impact of any credit enhancements to the contracts, are incorporated in the fair values to account for potential nonperformance risk, including our own nonperformance risk and the respective counterparty’s nonperformance risk. The fair value of interest rate caps is determined using the market-standard methodology of discounting the future expected cash receipts which would occur if variable interest rates rise above the strike rate of the caps. The variable interest rates used in the calculation of projected receipts on the cap are based on an expectation of future interest rates derived from observed market interest rate curves and volatilities. Although we have determined the majority of the inputs used to value our derivatives fall within Level 2 of the fair value hierarchy, the credit valuation adjustments associated with our derivatives utilize Level 3 inputs, such as estimates of current credit spreads, to evaluate the likelihood of default. However, we have assessed the significance of the impact of the credit valuation adjustments on the overall valuation of our derivative positions and have determined the credit valuation adjustments are not significant to the overall valuation of our derivatives. As a result, we have determined our derivative valuations in their entirety are classified in Level 2 of the fair value hierarchy. Non-recurring Fair Value Measurements. Certain assets are measured at fair value on a non-recurring basis. These assets are not measured at fair value on an ongoing basis, but are subject to fair value adjustments in certain circumstances. Long-lived assets such as the land, real estate asset, and in-place leases acquired with an operating property are measured in the form of cash received unless otherwise noted. These assets are recorded at fair value if they are impaired using the fair value methodologies used to measure long-lived assets described above at "Asset Impairment." Non-recurring fair value disclosures are not provided for impairments on assets disposed during the period because they are no longer owned by us. The inputs associated with the valuation of long-lived assets are generally included in Level 3 of the fair value hierarchy, unless a quoted price for a similar long-lived asset in an active market exists, at which time they are included in Level 2 of the fair value hierarchy. Financial Instrument Fair Value Disclosures. As of December 31, 2018 and 2017 , the carrying values of cash and cash equivalents, short-term investments, accounts receivable, accounts payable, accrued expenses and distributions payable represent fair value because of the short-term nature of these instruments. The carrying value of restricted cash approximates its fair value based on the nature of our assessment of the ability to recover these amounts. The carrying value of our notes receivable, which are included in other assets, net in our consolidated balance sheets, approximates their fair value. The estimated fair values are based on certain factors, such as market interest rates, terms of the note and credit worthiness of the borrower. These financial instruments utilize Level 3 inputs. In calculating the fair value of our notes payable, interest rate and spread assumptions reflect current credit worthiness and market conditions available for the issuance of notes payable with similar terms and remaining maturities. These financial instruments utilize Level 2 inputs. Income Recognition . Our rental revenue is recognized on a straight-line basis and other property revenue is recorded when due from residents and is recognized as it is earned. Other property revenue consists primarily of utility rebillings and administrative, application, and other transactional fees charged to our residents. Our apartment homes are rented to residents on lease terms generally ranging from twelve to fifteen months, with monthly payments due in advance. All other sources of income, including interest and fee and asset management income, are recognized as earned. See Note 3, "Revenues," for further discussion. Operations of multifamily properties acquired are recorded from the date of acquisition in accordance with the acquisition method of accounting. In management’s opinion, due to the number of residents, the types and diversity of submarkets in which our properties operate, and the collection terms, there is no significant concentration of credit risk. Reclassifications. Certain reclassifications have been made to amounts in prior period financial statements to conform to the current period presentation. As of December 31, 2018 , we reclassified certain insignificant amounts within investing activities which had no impact on our consolidated statements of cash flows for the years ended December 31, 2017 and 2016 . Insurance . Our primary lines of insurance coverage are property, general liability, health, and workers’ compensation. We believe our insurance coverage adequately insures our properties against the risk of loss attributable to fire, earthquake, hurricane, tornado, flood, and other perils and adequately insures us against other risks. Losses are accrued based upon our estimates of the aggregate liability for claims incurred using certain actuarial assumptions followed in the insurance industry and based on our experience. Other Assets, Net . Other assets in our consolidated financial statements include investments under deferred compensation plans, deferred financing costs, non-real estate leasehold improvements and equipment, notes receivable, prepaid expenses, and other miscellaneous receivables. Investments under deferred compensation plans are classified as trading securities and are adjusted to fair market value at period end. For a further discussion of our investments under deferred compensation plans, see Note 12, “Share-based Compensation and Benefit Plans.” Deferred financing costs are related to our unsecured credit facility and unsecured short-term borrowing facility, and are amortized no longer than the terms of the related facilities on the straight-line method, which approximates the effective interest method. Corporate leasehold improvements and equipment are depreciated using the straight-line method over the shorter of the expected useful lives or the lease terms which generally range from three to ten years. Notes Receivable. We have one note receivable included in Other assets, net in our consolidated balance sheets, relating to a real estate secured loan to an unaffiliated third party. During 2018, we received payments of approximately $9.5 million in principal and approximately $0.5 million in interest on this note which matures on October 1, 2025. At December 31, 2018 and 2017 , the outstanding note receivable balance was approximately $9.3 million and $18.8 million , respectively, and the weighted average interest rate was approximately 4.0% for each of the years ended December 31, 2018 and 2017 . Interest is recognized over the life of the note and is included in interest and other income in our consolidated statements of income and comprehensive income. We consider a note receivable to be impaired if it is probable we will not collect all contractually due principal and interest, and we do not accrue interest when a note is considered impaired and an allowance is recorded for any principal and previously accrued interest which is not believed to be collectible. All cash receipts on impaired notes are applied to reduce the principal amount of such notes until the principal has been recovered and, thereafter, are recognized as interest income. There were no impairments as of December 31, 2018 or 2017 . Reportable Segments . We operate in a single reportable segment which includes the ownership, management, development, redevelopment, acquisition, and construction of multifamily apartment communities. Each of our operating properties is considered a separate operating segment as each property earns revenues and incurs expenses, individual operating results are reviewed and discrete financial information is available. We do not distinguish or group our consolidated operations based on geography, size or type. Our multifamily apartment communities have similar long-term economic characteristics and provide similar products and services to our residents. Further, all material operations are within the United States and no multifamily apartment community comprises more than 10% of consolidated revenues. As a result, our operating properties are aggregated into a single reportable segment. Our multifamily communities generate rental revenue and other income through the leasing of apartment homes, which comprised approximately 99% of our total property revenues and total non-property income, excluding income on deferred compensation plans, for each of the years ended December 31, 2018 , 2017 , and 2016 . Restricted Cash . Restricted cash consists of escrow deposits held by lenders for property taxes, insurance and replacement reserves, cash required to be segregated for the repayment of residents’ security deposits, and escrowed amounts related to our development and acquisition activities. Substantially all restricted cash is invested in demand and short-term instruments. Share-based Compensation . Compensation expense associated with share-based awards is recognized in our consolidated statements of income and comprehensive income using the grant-date fair values. Compensation cost for all share-based awards, including options, requires measurement at estimated fair value on the grant date and recognition of compensation expense over the requisite service period for awards expected to vest. The fair value of stock option grants is estimated using the Black-Scholes valuation model. Valuation models require the input of assumptions, including judgments to estimate the expected stock price volatility, expected life, and forfeiture rate. The compensation cost for share-based awards is based on the market value of the shares on the date of grant and is adjusted as actual forfeitures occur. Use of Estimates . In the application of GAAP, management is required to make estimates and assumptions which affect the reported amounts of assets and liabilities at the date of the financial statements, results of operations during the reporting periods, and related disclosures. Our more significant estimates include estimates supporting our impairment analysis related to the carrying values of our real estate assets. These estimates are based on historical experience and other assumptions believed to be reasonable under the circumstances. Future events rarely develop exactly as forecasted, and the best estimates routinely require adjustment. Recent Accounting Pronouncements. In October 2018, the Financial Accounting Standards Board ("FASB") issue d Accounting Standards Update 2018-16 ("ASU 2018-16"), "Derivatives and Hedging (Topic 815): Inclusion of the Secured Overnight Financing Rate (SOFR) Overnight Index Swap (OIS) Rate as a Benchmark Interest Rate for Hedge Accounting Purposes." ASU 2018-16 permits the use of the overnight index swap rate based on the Secured Overnight Financing Rate to be used as a U.S. benchmark interest rate for hedge accounting purposes. ASU 2018-16 is effective for public entities which have already adopted ASU 2017-12 beginning after December 31, 2018. Since we already adopted ASU 2017-12, we adopted ASU 2018-16 as of January 1, 2019 with no impact on our existing hedges. We will consider these changes for qualifying new or redesignated hedging relationships entered into in the future. In August 2018, the FASB issued ASU 2018-15 "Intangibles—Goodwill and Other— Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract." ASU 2018-15 clarifies certain implementation costs relating to a cloud computing arrangement which is considered to be a service contract should be capitalized as if the arrangement was an internal-use software project. The standard also requires costs associated with an implementation to be classified where the fees are recorded in financial statements for such arrangements. ASU 2018-15 is effective for interim and annual periods beginning after December 15, 2019, and early adoption is permitted. This standard may be applied using the prospective transition method which is applicable to service contracts entered, renewed, or materially modified after the effective date or the retrospective transition method which allows us to recognize a cumulative effect adjustment to the opening balance of retained earnings, if any, as of the adoption date. We anticipate adopting ASU 2018-15 as of January 1, 2020, using the retrospective transition method and we do not expect our adoption to have a material impact on our consolidated financial statements. In August 2018, the FASB issued ASU 2018-13 " Fair Value Measurement (Topic 820): Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurement. " ASU 2018-13 removes, modifies, and adds certain fair value disclosure requirements including (i) the removal of disclosures regarding amounts, reasons, and timing for transfers between Levels 1 and 2 as well as descriptions of valuation processes used for Level 3 measurements of the fair value hierarchy; (ii) the modification of disclosures for the timing of liquidation of investee assets; (iii) the clarification of the narrative description of the measurement uncertainty of Level 3 fair value measurements at the reporting date does not need to include sensitivity of future changes; (iv) the addition of disclosures related to changes in unrealized gains and losses in other comprehensive income for recurring Level 3 fair value measurements to also be included in the statement of comprehensive income; and (v) the addition of disclosures for the range and weighted average of significant unobservable inputs. ASU 2018-13 is effective January 1, 2020 for the additional disclosures and early adoption of the removal and amended disclosures is allowed. We expect to adopt ASU 2018-13 as of January 1, 2020 and do not expect the adoption to have a material impact on our consolidated financial statements. In May 2014, the FASB issued ASU 2014-09 "Revenue from Contracts with Customers." ASU 2014-09 prescribes a single, common revenue standard to replace most existing revenue recognition guidance in GAAP, including most industry-specific requirements. The standard outlines a five-step model whereby revenue is recognized as performance obligations within a contract are satisfied. Several ASUs intended to promote a more consistent interpretation and application of the principles outlined in the standard have been issued since the issuance of ASU 2014-09 which modify certain sections of the new revenue recognition standard. We adopted ASU 2014-09 and all related amendments effective January 1, 2018 using the modified retrospective with cumulative effect transition method. This method requires us to recognize the cumulative effect of initially applying the new revenue standard as an adjustment, if any, to the opening balance of retained earnings, which had no impact on our consolidated financial statements upon adoption. See Note 3, "Revenues," for additional disclosures required by the ASU. In February 2016, the FASB issued ASU 2016-02, "Leases." ASU 2016-02 supersedes the current accounting for leases. The new lease standard retains three distinct types of leases which are similar to existing guidance for lessors: operating, sales-type, and financing, and aligns many of the underlying lessor model principles with those in the new revenue standard. For lessees, the new lease standard retains two distinct types of leases, finance and operating; and (i) requires lessees to record a right of use asset and a related liability for the rights and obligations associated with a lease, regardless of lease classification, and recognize lease expense in a manner similar to current accounting and (ii) eliminates most real estate specific lease provisions. We adopted ASU 2016-02 and its related amendments as of January 1, 2019 using the transition practical expedient which allows us to recognize a cumulative-effect adjustment to the opening balance of retained earnings as of the adoption date as well as other elected practical expedients. We have identified our lease commitments and finalized our evaluation on our consolidated financial statements and on our internal accounting processes. Substantially all of our real estate lessor commitments will continue to be accounted for as operating leases and the new leasing standard will not have a material impact on rental revenues. Our lessee operating lease commitments are subject to the standard and recognized as operating lease

Revenue Recognition, Leases [Abstract]
Revenue Recognition, Leases [Policy Text Block]	3. Revenue On January 1, 2018, we adopted ASU 2014-09 and all related amendments in accordance with ASU 2014-09 and elected to apply the new revenue standard to those contracts which were not completed as of January 1, 2018. We also elected to omit disclosing the value of unsatisfied performance obligations for (i) contracts with an original expected length of one year or less and (ii) contracts for which the invoiced amount directly corresponds to the value transferred to the customer as provided for in the practical expedients. Our adoption of ASU 2014-09 and its related amendments did not have a material impact upon our consolidated financial statements as the majority of our revenues are derived from real estate lease contracts which are scoped out of ASU 2014-09. Our presentation of revenue within our condensed consolidated statements of income and comprehensive income is separated into its component parts by the nature and timing of the revenue streams. Our revenue within the scope of this new revenue standard is recognized when the services are transferred to our customers for an amount which reflects the consideration we expect to receive in exchange for those services rendered and include the following: Other Property Revenues. The items within other property revenues relate to non-lease components within a lease contract and primarily consist of utility rebillings which are usually recognized over time and other transactional fees primarily recognized at a point-in-time. These fees are charged to our residents and recognized monthly as the performance obligation is satisfied. Upon our adoption of ASU 2014-09, we are now presenting certain revenue items, historically included as a component of other property revenues, as rental revenues due to the nature and timing of revenue recognition for these items being more closely aligned to a lease. This new presentation has been applied prospectively as this reclassification will not have an impact upon total property revenues or the opening balance of retained earnings. Approximately $22.2 million of rental revenue is related to this presentation for the year ended December 31, 2018 . Had ASU 2014-09 been effective as of January 1, 2017, we would have reclassified approximately $21.9 million from other property revenues to rental revenue for the year ended December 31, 2017 . Fee and Asset Management Income. Management fee income primarily consists of fees charged to our unconsolidated joint ventures for managing the joint venture, and the development, redevelopment and capital expenditures of their operating communities. While the individual activities related to these fees may vary, the services provided are substantially similar, have the same pattern of transfer, and are considered to be individual performance obligations composed of a series of distinct services, recognized monthly as earned. We also generate construction fees for construction management and general contracting services provided to third-party owners of multifamily, commercial, and retail properties. These fees are recognized as we satisfy our single performance obligation over time based on a percentage-of-completion of cost basis which we believe is an accurate depiction of the transfer of control to our customers. For these contracts, significant judgment is used to estimate the cost plus margin for the project fee and our profitability on those contracts is dependent on the ability to accurately predict such factors. Contract Balances. We record third-party construction receivables for amounts where we have unconditional rights to payment but have not received and liabilities for amounts incurred but not paid. For the years ended December 31, 2018 and 2017 , these contract receivable and liability balances were immaterial.

Earnings Per Share [Abstract]
Per Share Data	4. Per Share Data Basic earnings per share are computed using net income attributable to common shareholders and the weighted average number of common shares outstanding. Diluted earnings per share reflect common shares issuable from the assumed conversion of common share options and share awards granted and units convertible into common shares. Only those items having a dilutive impact on our basic earnings per share are included in diluted earnings per share. Our unvested share-based awards are considered participating securities and are reflected in the calculation of basic and diluted earnings per share using the two-class method. The number of common share equivalent securities excluded from the diluted earnings per share calculation was approximately 2.1 million , 1.5 million , and 2.4 million for the years ended December 31, 2018 , 2017 , and 2016 , respectively. These securities, which include common share options and share awards granted and units convertible into common shares, were excluded from the diluted earnings per share calculation as they are anti-dilutive. The following table presents information necessary to calculate basic and diluted earnings per share for the periods indicated: Year Ended December 31, (in thousands, except per share amounts) 2018 2017 2016 Earnings per common share calculation – basic Income from continuing operations attributable to common shareholders $ 156,128 $ 196,422 $ 436,981 Amount allocated to participating securities (1,107 ) (660 ) (6,304 ) Income from continuing operations attributable to common shareholders, net of amount allocated to participating securities $ 155,021 $ 195,762 $ 430,677 Discontinued operations, including gain on sale, attributable to common shareholders — — 382,842 Net income attributable to common shareholders – basic $ 155,021 $ 195,762 $ 813,519 Earnings per common share from continuing operations $ 1.63 $ 2.14 $ 4.81 Earnings per common share from discontinued operations — — 4.27 Total earnings per common share – basic $ 1.63 $ 2.14 $ 9.08 Weighted average number of common shares outstanding – basic 95,208 91,499 89,580 Year Ended December 31, (in thousands, except per share amounts) 2018 2017 2016 Earnings per common share calculation – diluted Income from continuing operations attributable to common shareholders, net of amount allocated to participating securities $ 155,021 $ 195,762 $ 430,677 Income allocated to common units from continuing operations — 1,174 — Income from continuing operations attributable to common shareholders, as adjusted $ 155,021 $ 196,936 $ 430,677 Discontinued operations, including gain on sale, attributable to common shareholders — — 382,842 Net income attributable to common shareholders – diluted $ 155,021 $ 196,936 $ 813,519 Earnings per common share from continuing operations $ 1.63 $ 2.13 $ 4.79 Earnings per common share from discontinued operations — — 4.26 Total earnings per common share – diluted $ 1.63 $ 2.13 $ 9.05 Weighted average number of common shares outstanding – basic 95,208 91,499 89,580 Incremental shares issuable from assumed conversion of: Common share options and share awards granted 158 211 323 Common units — 805 — Weighted average number of common shares outstanding – diluted 95,366 92,515 89,903

Stockholders' Equity Note [Abstract]
Common Shares [Text Block]	5. Common Shares In May 2017, we created an at-the market ("ATM") share offering program through which we can, but have no obligation to, sell common shares having an aggregate offering price of up to $315.3 million (the "2017 ATM program"), in amounts and at times as we determine, into the existing trading market at current market prices as well as through negotiated transactions. Actual sales from time to time may depend on a variety of factors including, among others, market conditions, the trading price of our common shares, and determinations by management of the appropriate sources of funding for us. The proceeds from the sale of our common shares under the 2017 ATM program are intended to be used for general corporate purposes, which may include reducing future borrowings under our unsecured line of credit or short-term borrowing facilities, the repayment of other indebtedness, the redemption or other repurchase of outstanding debt or equity securities, funding for development activities, and financing for acquisitions. For the year ended December 31, 2018, we did not sell any shares under the 2017 ATM program. The following table presents activity under the 2017 ATM program for the year ended December 31, 2017: (in thousands, except per share amounts) Year Ended December 31, 2017 Total net consideration $ 2,513.6 Common shares sold 28.1 Average price per share $ 90.44 As of the date of this filing, we had common shares having an aggregate offering price of up to $312.8 million remaining available for sale under the 2017 ATM program. No additional shares were sold under the 2017 ATM program subsequent to December 31, 2018 through the date of this filing. We have a repurchase plan approved by our Board of Trust Managers which allows for the repurchase of up to $500 million of our common equity securities through open market purchases, block purchases, and privately negotiated transactions. In 2018, we repurchased 3,222 common shares for approximately $0.3 million . As of the date of this filing, the remaining dollar value of our common equity securities authorized to be repurchased under the program was approximately $269.5 million . There were no repurchases for the years ended December 31, 2017 or 2016 under this program, or subsequent to December 31, 2018 through the date of this filing. We currently have an automatic shelf registration statement which allows us to offer, from time to time, common shares, preferred shares, debt securities, or warrants. Our Amended and Restated Declaration of Trust provides we may issue up to 185 million shares of beneficial interest, consisting of 175 million common shares and 10 million preferred shares. At December 31, 2018 , we had approximately 93.2 million common shares outstanding, net of treasury shares and shares held in our deferred compensation arrangements, and no preferred shares outstanding. In addition to our 2016 quarterly dividends, our Board of Trust Managers declared a special dividend of $ 4.25 per common share to our common shareholders of record as of September 23, 2016 , consisting of gains on dispositions of assets completed in 2016, which was paid on September 30, 2016 . We also paid equivalent amounts per unit to holders of the common operating partnership units.

Operating Partnerships [Abstract]
Operating Partnerships [Text Block]	6. Operating Partnerships At December 31, 2018 , approximately 4% of our consolidated multifamily apartment homes were held in Camden Operating, L.P. (“Camden Operating” or the “operating partnership”). Camden Operating has 11.9 million outstanding common limited partnership units and as of December 31, 2018 , we held approximately 92% of the outstanding common limited partnership units and the sole 1% general partnership interest of the operating partnership. The remaining common limited partnership units, comprising approximately 0.8 million units, are primarily held by former officers, directors, and investors of Paragon Group, Inc., which we acquired in 1997. Each common limited partnership unit is redeemable for one common share of Camden Property Trust or cash at our election. Holders of common limited partnership units are not entitled to rights as shareholders prior to redemption of their common limited partnership units. No member of our management owns Camden Operating common limited partnership units. At December 31, 2018 , approximately 33% of our consolidated multifamily apartment homes were held in Camden Summit Partnership, L.P. (the “Camden Summit Partnership”). Camden Summit Partnership has 22.8 million outstanding common limited partnership units and as of December 31, 2018 , we held approximately 95% of the outstanding common limited partnership units and the sole 1% general partnership interest of Camden Summit Partnership. The remaining common limited partnership units, comprising approximately 1.0 million units, are primarily held by former officers, directors, and investors of Summit Properties Inc., which we acquired in 2005. Each common limited partnership unit is redeemable for one common share of Camden Property Trust or cash at our election and holders of common limited partnership units are not entitled to rights as shareholders prior to redemption of their common limited partnership units. No member of our management owns Camden Summit Partnership common limited partnership units, and two of our ten trust managers own Camden Summit Partnership common limited partnership units. During 2018, we entered into an agreement with certain holders of common units of limited partnership interest in the Camden Summit Partnership, which holders included two of our Trust Managers. This agreement modifies the original terms of the Tax Protection Agreement dated February 28, 2005 which states the Camden Summit Partnership must maintain a certain amount of secured debt until February 28, 2020 to protect the negative tax capital of the unitholders or reimburse the unitholders for income taxes incurred from the repayment of this indebtedness. Pursuant to this 2018 agreement, Camden Summit Partnership issued $100.0 million of unsecured debt with an unrelated third party which was guaranteed by Camden Property Trust. Additionally, each such unitholder agreed to indemnify Camden Property Trust for their portion of the unsecured debt equal to the amount of income and gain which would be required to be recognized by the unitholder due to their negative tax capital account; the indemnities are for a one-year period with an annual October 15 renewal right. These amounts were approximately $21.2 million in the aggregate for the two Trust Managers which are holders of common units of limited partner interest in Camden Summit Partnership. In return, Camden Summit Partnership agreed to extend the duration of the Tax Protection Agreement for two years for each year such unitholder's indemnification agreement remains in place.

In order for us to continue to qualify as a REIT we must meet a number of organizational and operational requirements, including a requirement to distribute annual dividends to our shareholders equal to a minimum of 90% of our adjusted taxable income. As a REIT, we generally will not be subject to federal income tax on our taxable income at the corporate level to the extent such income is distributed to our shareholders annually. If our taxable income exceeds our dividends in a tax year, REIT tax rules allow us to designate dividends from the subsequent tax year in order to avoid current taxation on undistributed income. If we fail to qualify as a REIT in any taxable year, we will be subject to federal and state income taxes at regular corporate rates, including for taxable years ended before January 1, 2019 any applicable alternative minimum tax. In addition, we may not be able to requalify as a REIT for the four subsequent taxable years. Historically, we have incurred only state and local income, franchise, and excise taxes. Taxable income from non-REIT activities managed through taxable REIT subsidiaries is subject to applicable federal, state, and local income taxes. Our operating partnerships are flow-through entities and are not subject to federal income taxes at the entity level. We have recorded income, franchise, and excise taxes in the consolidated statements of income and comprehensive income for the years ended December 31, 2018 , 2017 and 2016 as income tax expense. Income taxes for the years ended December 31, 2018 , 2017 and 2016 , primarily related to state income tax and federal taxes on certain of our taxable REIT subsidiaries. We have no significant temporary or permanent differences or tax credits associated with our taxable REIT subsidiaries. For income tax purposes, distributions to common shareholders are characterized as ordinary income, capital gains or as a return of a shareholder's invested capital. A summary of the income tax characterization of our distributions paid per common share for the years ended December 31, 2018 , 2017 and 2016 is set forth in the following table: Year Ended December 31, 2018 2017 2016 Common Share Distributions Ordinary income $ 2.99 $ 2.38 $ — Long-term capital gain 0.09 0.41 5.02 Unrecaptured Sec. 1250 gain — 0.21 2.23 Total $ 3.08 $ 3.00 $ 7.25 We have taxable REIT subsidiaries which are subject to federal and state income taxes. At December 31, 2018 , our taxable REIT subsidiaries had immaterial net operating loss carryforwards (“NOL’s”) which expire in years 2034 to 2037 and no benefits related to these NOL’s have been recognized in our consolidated financial statements. The carrying value of net assets reported in our consolidated financial statements at December 31, 2018 exceeded the tax basis by approximately $1.3 billion . Income Tax Expense . For the tax year ended December 31, 2018 , we had income tax expense of approximately $1.4 million , and $1.2 million and $1.6 million for the tax years ended December 31, 2017 and 2016 , respectively. Income tax for the years ended December 31, 2018 , 2017 , and 2016 was comprised mainly of state income tax and federal income tax related to one of our taxable REIT subsidiaries. Income Tax Expense – Deferred . For the years ended December 31, 2018 , 2017 , and 2016 , our deferred tax expense was not significant. The income tax returns of Camden Property Trust and its subsidiaries are subject to examination by federal, state and local tax jurisdictions for years 2015 through 2017 . Tax attributes generated in years prior to 2015 are also subject to challenge in any examination of those tax years. We believe we have no uncertain tax positions or unrecognized tax benefits requiring disclosure as of and for the periods presented. Tax reform . The 2017 Tax Act was passed on December 22, 2017 which includes a number of changes to the corporate income tax system, including but not limited to a reduction in the statutory federal corporate income tax rate from 35% to 21% for non-REIT “C” corporations, changes to deductions for certain pass-through business income, and possible limitations on interest expense, depreciation and the deductibility of executive compensation. As a REIT, we generally will not be subject to federal income tax on our taxable income at the corporate level and the changes from the 2017 Tax Act did not have a material impact on our consolidated financial statements.

Equity Method Investments and Joint Ventures [Abstract]
Investments In Joint Ventures	9. Investments in Joint Ventures Our equity investments in unconsolidated joint ventures, which we account for utilizing the equity method of accounting, consists of three funds (collectively, the "Funds"). At December 31, 2018 , 2017 , and 2016 , we had two discretionary investment funds in which we had an ownership interest of 31.3% in each of these funds. In March 2015, we completed the formation of a third fund with an unaffiliated third party for additional multifamily investments of up to $450.0 million . We have a 20.0% ownership interest in this third fund, and it did not own any properties in 2018 , 2017 , or 2016 . We provide property and asset management and other services to the Funds which own operating properties and we may also provide construction and development services to the Funds which own properties under development. The following table summarizes the combined balance sheet and statement of income data for the Funds as of and for the periods presented: (in millions) 2018 2017 Total assets $ 695.2 $ 715.9 Total third-party debt 510.7 514.5 Total equity 158.4 174.5 2018 2017 2016 Total revenues $ 127.4 $ 121.9 $ 119.8 Net income (1) 16.4 13.5 14.8 Equity in income (2) (3) 7.8 6.8 7.1 (1) Net income for the years ended December 31, 2017 includes approximately $1.3 million of property expense, respectively, relating to Hurricanes Harvey and Irma in the third quarter of 2017. (2) Equity in income excludes our ownership interest of fee income from various services provided by us to the Funds. (3) Equity in income for the years ended December 31, 2017 includes our ownership interest of the hurricane related recoveries and expenses of approximately $0.4 million , respectively. The Funds in which we have a partial interest have been funded in part with secured third-party debt. As of December 31, 2018 , we had no outstanding guarantees related to debt of the Funds. We may earn fees for property and asset management, construction, development, and other services related to joint ventures in which we own an equity interest and may earn a promoted equity interest if certain thresholds are met. We eliminate fee income for services provided to these joint ventures to the extent of our ownership. Fees earned for these services, net of eliminations, were approximately $5.7 million , $5.8 million , and $5.3 million for the years ended December 31, 2018 , 2017 , and 2016 , respectively.

In August 2015, we amended and restated our $500 million unsecured credit facility, which extended the maturity date from September 2015 to August 2019 , with two six-month options to extend the maturity date at our election to August 2020 , and increased the availability to $600 million , with the option to further increase it to $900 million by either adding additional banks to the facility or obtaining the agreement of the existing banks to increase their commitments. The interest rate on this credit facility is based upon the London Interbank Offered Rate ("LIBOR") plus a margin which is subject to change as our credit ratings change. Advances under this credit facility may be priced at the scheduled rates, or we may enter into bid rate loans with participating banks at rates below the scheduled rates. These bid rate loans have terms of 180 days or less and may not exceed the lesser of $300 million or the remaining amount available under the credit facility. This credit facility is subject to customary financial covenants and limitations. We believe we are in compliance with all such financial covenants and limitations on the date of this filing. Our credit facility provides us with the ability to issue up to $50 million in letters of credit. While our issuance of letters of credit does not increase our borrowings outstanding under our credit facility, it does reduce the amount available. At December 31, 2018 , we had no amounts outstanding on our $600 million credit facility and we had outstanding letters of credit totaling approximately $10.1 million , leaving approximately $589.9 million available under our credit facility. In May 2018, we extended the term on our $45.0 million unsecured short-term borrowing facility from May 2018 to May 2019 . The interest rate is based on LIBOR plus 0.95% . At December 31, 2018 , we had no amounts outstanding on this unsecured short-term borrowing facility, leaving $45.0 million available under this facility. In September 2018, we entered into a $100.0 million three -year unsecured floating-rate term loan with an unrelated third party, which was funded in October 2018. The interest rate on the term loan is based on LIBOR plus a margin which is subject to change as our credit ratings change. See Note 6, "Operating Partnerships" for a further discussion of this transaction. In October 2018, we repaid at maturity our $175.0 million variable rate secured conventional mortgage notes and $205.0 million of outstanding fixed rate secured conventional mortgage notes which were scheduled to mature in 2018 from our unsecured line of credit, other short-term borrowings, and the $100.0 million term loan discussed above. Also in October 2018, we issued $400.0 million aggregate principal amount of 4.100% senior unsecured notes due October 15, 2028 (the "2028 Notes") under our existing shelf registration statement. The 2028 Notes were offered to the public at 99.893% of their face amount with a stated rate of 4.100% and a yield to maturity of 4.113% . After giving effect to the settlement of the swap agreements as discussed below in Note 11, "Derivative Financial Instruments and Hedging Activities," and deducting the underwriting discounts and other estimated expenses of the offering, the effective annual interest rate on the 2028 Notes is approximately 3.74% . We received net proceeds of approximately $396.1 million , net of underwriting discounts and other estimated offering expenses. Interest on the 2028 Notes is payable semi-annually on April 15 and October 15, beginning April 15, 2019. We may redeem the 2028 Notes, in whole or in part, at any time at a redemption price equal to the principal amount and accrued interest of the notes being redeemed, plus a make-whole provision. If, however, we redeem the 2028 Notes 90 days or fewer prior to the maturity date, the redemption price will equal 100% of the principal amount of the 2028 Notes to be redeemed plus accrued and unpaid interest on the amount being redeemed to the redemption date. The 2028 Notes are direct, senior unsecured obligations and rank equally with all of our other unsecured and unsubordinated indebtedness. We used the proceeds from the offering of the 2028 Notes to repay outstanding balances on our unsecured line of credit and other short-term borrowings (including amounts incurred to repay the $380.0 million secured unconventional mortgage notes) and the remainder for general corporate purposes. At December 31, 2018 , we had $99.6 million outstanding floating rate debt with a weight average interest rate on this debt of approximately 3.3% . At December 31, 2017 , we had outstanding floating rate debt of approximately $175.0 million with a weighted average interest rate on this debt of approximately 1.9% . Our indebtedness had a weighted average maturity of 4.9 years at December 31, 2018 . The table below is a summary of the maturity dates of our outstanding debt and principal amortizations, and the weighted average interest rates on such debt, at December 31, 2018 : (in millions) Amount Weighted Average Interest Rate 2019 $ 437.3 5.2 % 2020 (1) (1.9 ) — 2021 248.5 4.8 2022 448.8 3.2 2023 249.8 5.1 Thereafter 939.1 3.9 Total $ 2,321.6 4.2 % (1) Includes only amortization of debt discounts and debt issuance costs, net of scheduled principal payments. Subsequent to December 31, 2018, we repaid $200.0 million of secured notes utilizing our unsecured credit facility.

Derivative Instruments and Hedging Activities Fair Value [Abstract]
Derivative Instruments and Hedging Activities Disclosure [Text Block]	11. Derivative Financial Instruments and Hedging Activities Risk Management Objective of Using Derivatives. We are exposed to certain risks arising from both our business operations and economic conditions. We principally manage our exposures to a wide variety of business and operational risks through management of our core business activities. We manage economic risks, including interest rate, liquidity, and credit risk, primarily by managing the amount, sources, and duration of our debt funding and the use of derivative financial instruments. Specifically, we may enter into derivative financial instruments to manage exposures arising from business activities resulting in differences in the amount, timing, and duration of our known or expected cash payments principally related to our borrowings. See Note 2, "Summary of Significant Accounting Policies and Recent Accounting Pronouncements" for a further discussion of derivative financial instruments. Cash Flow Hedges of Interest Rate Risk. Our objectives in using interest rate derivatives are to add stability to interest expense and to manage our exposure to interest rate movements. To accomplish these objectives, we primarily use interest rate swaps and caps as part of our interest rate risk management strategy. Interest rate swaps involve the receipt of variable rate amounts from a counterparty in exchange for us making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount. Interest rate caps involve the receipt of variable rate amounts from a counterparty if interest rates rise above the strike rate on the contract in exchange for an upfront premium. Our interest rate swaps and caps hedge interest expense and net proceeds from the settlement of such hedges will be classified as operating activities in the consolidated statement of cash flows. Designated Hedges. The gain or loss on the derivatives designated and qualifying as cash flow hedges is reported as a component of other comprehensive income or loss and subsequently reclassified into earnings in the period the hedged forecasted transaction affects earnings and presented in the same line item as the earnings effect of the hedged item. During 2018, we entered into four designated hedges with a total notional value of $500.0 million to hedge a portion of anticipated future fixed rate debt issuances in 2018 and 2019. At December 31, 2018, we had a total of two designated hedges outstanding with a total notional value of $300.0 million to hedge a portion of anticipated future fixed rate debt issuances in 2019. At December 31, 2017, we had a total of three designated hedges outstanding with a total notional value of $200.0 million to hedge a portion of anticipated future fixed rate debt issuances in 2018. In connection with the issuance of our 2028 Notes, we settled an aggregate of $400.0 million forward interest rate swap designated hedges resulting in a cash receipt of approximately $15.9 million which was recorded in accumulated other comprehensive income on our consolidated balance sheets and will be recognized over the life of the issued debt as an adjustment to interest expense. Non-Designated Hedges. Derivatives are not entered into for trading or speculative purposes and are used to manage our exposure to interest rate movements and other identified risks. Our non-designated hedges are either specifically non-designated by management or do not meet strict hedge accounting requirements. Changes in the fair value of derivatives not designated in hedging relationships are recorded directly in earnings in interest and other income. At December 31, 2018 and 2017, we did not have any non-designated hedges outstanding. The table below presents the fair value of our derivative financial instruments as well as their classification in the consolidated balance sheets at December 31, 2018 and 2017: Asset Derivatives Liability Derivatives December 31, 2018 (1) December 31, 2017 December 31, 2018 (1) December 31, 2017 (in millions) Balance Sheet Fair Balance Sheet Fair Balance Sheet Fair Balance Sheet Fair Derivatives designated as hedging instruments Interest Rate Swaps Other Assets $ — Other Assets $ 2.2 Other Liabilities $ 7.4 Other Liabilities $ 0.5 (1) The derivatives subject to master netting arrangements are presented on a gross basis on our condensed consolidated balance sheet as of December 31, 2018 . There were no derivative contracts in a master netting arrangement as of December 31, 2018 and 2017. The table below presents the effect of our derivative financial instruments in the consolidated statements of income and comprehensive income for the year ended December 31, 2018 and 2017: (in millions) Unrealized Gain Recognized in Other Location of Gain Amount of Gain Derivatives in Cash Flow Hedging Relationships 2018 2017 2018 2017 Interest Rate Swaps $ 6.8 $ 1.7 Interest expense $ 0.4 $ — As of December 31, 2018 , the amount we expect to be reclassified into earnings in the next 12 months as a decrease to interest expense is approximately $0.7 million . Credit-Risk-Related Contingent Features. Derivative financial investments expose us to credit risk in the event of non-performance by the counterparties under the terms of the interest rate hedge agreements. The Company has an agreement with a derivative counterparty that contains 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, 2018 , the fair value of derivatives in a net liability position, which excludes any adjustment for nonperformance risk, related to these agreements was approximately $7.4 million .

Share-based Compensation [Abstract]
Share-Based Compensation and Benefit Plans	12. Share-based Compensation and Benefit Plans Incentive Compensation. We currently maintain the 2018 Share Incentive Plan (the “2018 Share Plan”) and the 2011 Share Incentive Plan (the “2011 Share Plan”), although no new awards may be granted under the 2011 Plan. Each of these plans were approved by the Company’s shareholders. The shares available for awards under the 2018 Share Plan are, subject to certain other limits under the plan, generally available for any type of award authorized under the 2018 Share Plan, including stock options, stock appreciation rights, restricted stock awards, stock bonuses and other stock-based awards. Persons eligible to receive awards under the 2018 Share Plan include officers and employees of the Company or any of its subsidiaries, Trust Managers of the Company, and certain consultants and advisors to the Company or any of its subsidiaries. A total of 9.7 million shares (“Share Limit”) was authorized under the 2018 Share Plan. Shares issued or to be issued are counted against the Share Limit as set forth as (1) 3.45 to 1.0 for every share award, excluding stock options and share appreciation rights, granted, and (2) 1.0 to 1.0 for every share of stock option or share appreciation right granted. As of December 31, 2018 , there were approximately 8.2 million common shares available under the 2018 Share Plan, which would result in approximately 2.4 million shares which could be granted pursuant to full value awards conversion ratios as defined under the plan. Total compensation cost for option and share awards charged against income was approximately $17.8 million , $ 18.8 million , and $ 21.3 million for 2018 , 2017 and 2016 , respectively. Total capitalized compensation cost for option and share awards was approximately $3.0 million for the year ended December 31, 2018 , and was $3.8 million for both years ended December 31, 2017, and 2016. A summary of activity under our share incentive plans for the year ended December 31, 2018 is shown below: Options Outstanding Weighted Average Exercise / Grant Price Nonvested Share Awards Outstanding Weighted Average Exercise / Grant Price Options and nonvested share awards outstanding at December 31, 2017 68,978 $ 61.15 499,898 $ 75.80 Granted 9,994 78.55 232,478 82.81 Exercised/Vested (78,972 ) 63.35 (316,668 ) 75.66 Forfeited — — (25,027 ) 79.83 Total options and nonvested share awards outstanding at December 31, 2018 — $ — 390,681 $ 79.82 Options. Stock options other than reload options have a contractual life of ten years and vest over periods up to five years. Reload options vest at the grant date. Reload options are granted for the number of shares tendered as payment for the exercise price upon the exercise of an option with a reload provision. The reload options granted had an exercise price equal to the fair market value of a common share on the date of grant and expired on the same date as the original options which were exercised. None of our current incentive compensation plans carry reload option rights, and all of our obligations relating to reload options have been satisfied as of December 31, 2018. Expense for stock options is based on grant date fair value and recognized on a straight-line method over the vesting period. We estimate the fair values of each option award on the date of grant using the Black-Scholes option pricing model. The weighted-average fair value of reload stock options granted during the years ended December 31, 2018, 2017 and 2016 and the weighted-average assumptions for such grants were as follows: Year Ended Year Ended Year Ended December 31, 2016 Weighted average fair value of options granted $4.11 $5.25 $6.71 Expected volatility 15.1% 18.9% 18.0% Risk-free interest rate 2.0% 1.3% 0.9% Expected dividend yield 3.3% 5.5% 3.8% Expected life 1 year 2 years 3 years Our computations of expected volatility for 2018 , 2017 , and 2016 are based on the historical volatility of our common shares over a time period equal to the expected life of the option and ending on the grant date, and the interest rate for periods within the contractual life of the award is based on the U.S. Treasury yield curve in effect at the time of grant. The expected dividend yield on our common shares is based on the historical dividend yield over the expected term of the options granted. Our computation of expected life is based upon historical experience of similar awards, giving consideration to the contractual terms of the share-based awards. The total intrinsic value of options exercised was approximately $2.0 million , $2.2 million , and $8.9 million during the years ended December 31, 2018 , 2017, and 2016, respectively. At December 31, 2018 , there was no unrecognized compensation cost related to unvested options and there were no options outstanding. Share Awards and Vesting. Share awards for employees vest over periods up to five years and are valued at the market value of the shares on the grant date. In the event the holder of the share awards attains at least age 65, with ten or more years of service ("Retirement Eligibility") before the term in which the awards are scheduled to vest, the value of the share awards is amortized from the date of grant to the individual's Retirement Eligibility date. At December 31, 2018 , the weighted average fair value of share awards granted was $82.81 , $83.41 and $74.92 in 2018, 2017 and 2016, respectively. The total fair value of shares vested during the years ended December 31, 2018 , 2017 and 2016 was approximately $24.0 million , $ 23.1 million , and $ 27.2 million , respectively. At December 31, 2018 , the unamortized value of previously issued unvested share awards was approximately $15.4 million which is expected to be amortized over the next two years. Employee Share Purchase Plan (“ESPP”). In May 2018, our shareholders approved the 2018 Employee Share Purchase Plan (the "2018 ESPP") which amends and restates our 1999 Employee Share Purchase Plan (the "1999 ESPP") effective with the offering period commencing in June 2018. Under the 2018 ESPP, we may issue up to a total of approximately 500,000 common shares. The 2018 ESPP permits eligible employees to purchase our common shares either through payroll deductions or through semi-annual contributions. Each offering period has a six month duration commencing in June and December for which shares may be purchased at 85% of the market value, as defined on the first or last day of the offering period, whichever price is lower. We currently use treasury shares to satisfy ESPP share requirements. Each participant must hold the shares purchased for nine months in order to receive the discount, and a participant may not purchase more than $25,000 in value of shares during any plan year, as defined. The following table presents information related to our ESPP: 2018 2017 2016 Shares purchased 15,330 18,986 20,797 Weighted average fair value of shares purchased $ 90.93 $ 89.89 $ 82.33 Expense recorded (in millions) $ 0.2 $ 0.3 $ 0.4 Rabbi Trust. We established a rabbi trust for a select group of participants in which share awards granted under the share incentive plan and salary and other cash amounts earned may be deposited. The rabbi trust is only in use for deferrals made prior to 2005, including bonuses related to service in 2004 but paid in 2005. The rabbi trust is an irrevocable trust and no portion of the trust fund may be used for any purpose other than the delivery of those assets to the participants. The assets held in the rabbi trust are subject to the claims of our general creditors in the event of bankruptcy or insolvency. The value of the assets of the rabbi trust is consolidated into our financial statements. Granted share awards held by the rabbi trust are classified in equity in a manner similar to the manner in which treasury stock is accounted. Subsequent changes in the fair value of the shares are not recognized. The deferred compensation obligation is classified as an equity instrument and changes in the fair value of the amount owed to the participant are not recognized. At both December 31, 2018 and 2017 , approximately 1.7 million share awards were held in the rabbi trust. Additionally, as of December 31, 2018 and 2017 , the rabbi trust held trading securities totaling approximately $14.9 million and $26.7 million , respectively, which represents cash deferrals made by plan participants. Market value fluctuations on these trading securities are recognized in income in accordance with GAAP and the liability due to participants is adjusted accordingly. At December 31, 2018 and 2017 , approximately $ 21.2 million and $ 22.3 million , respectively, was required to be paid to us by plan participants upon the withdrawal of any assets from the rabbi trust, and is included in “Accounts receivable-affiliates” in our consolidated financial statements. Non-Qualified Deferred Compensation Share Awards. In 2004, we established a Non-Qualified Deferred Compensation Plan which is an unfunded arrangement established and maintained primarily for the benefit of a select group of participants. Eligible participants commence participation in this plan on the date the deferral election first becomes effective. We credit to the participant's account an amount equal to the amount designated as the participant's deferral for the plan year as indicated in the participant's deferral election(s). Any modification to or termination of the plan will not reduce a participant's right to any vested amounts already credited to his or her account. Approximately 0.7 million and 1.0 million share awards were held in the plan at December 31, 2018 and 2017 , respectively. Additionally, as of December 31, 2018 and 2017 , the plan held trading securities totaling approximately $129.8 million and $ 93.6 million , respectively, which represents cash deferrals made by plan participants and diversification of share awards within the plan to trading securities. Market value fluctuations on these trading securities are recognized in income in accordance with GAAP and the liability due to participants is adjusted accordingly. The assets held in the Non-Qualified Deferred Compensation Plan are subject to the claims of our general creditors in the event of bankruptcy or insolvency. The plan, as amended, permitted diversification of fully vested share awards into other equity securities subject to a six month holding period. Balances within temporary equity in our consolidated balance sheets relate to fully vested awards and the proportionate share of nonvested awards of participants within our Non-Qualified Deferred Compensation Plan who were permitted to diversify their shares into other equity securities. The following table summarizes the eligible share award activity for the twelve months ended December 31: (in thousands) 2018 2017 Temporary equity: Balance at inception/beginning of period $ 77,230 $ 77,037 Change in classification 16,407 13,388 Change in redemption value (669 ) 10,038 Diversification of share awards (429 and 261 shares during December 31, 2018 and 2017, respectively) (40,294 ) (23,233 ) Balance at December 31 $ 52,674 $ 77,230 In December 2018, the plan was amended and restated and effective January 1, 2019 participants in the plan are no longer able to diversify their common shares six months after vesting. Thus, the fully vested share awards and the proportionate share of nonvested share awards eligible for diversification at the amendment date were reclassified on the effective date from temporary equity into additional paid-in capital in our consolidated balance sheet. Deferred share-based compensation cannot be diversified, and distributions from this plan are made in the same form as the original deferral. 401(k) Savings Plan. We have a 401(k) savings plan, which is a voluntary defined contribution plan, which provides participating employees the ability to elect to contribute up to 60 percent of eligible compensation, subject to limitations as defined by the federal tax code, with the Company making matching contributions up to a predetermined limit. The matching contributions made for the year ended December 31, 2018 , was approximately $2.9 million , and were approximately $2.7 million for the each of the years ended December 31, 2017 and 2016 . Employees become vested in our matching contributions 33% after one year of service, 67% after two years of service and 100% after three years of service.

Nonrecurring Fair Value Disclosures. The nonrecurring fair value disclosures inputs under the fair value hierarchy are discussed in Note 2, “Summary of Significant Accounting Policies and Recent Accounting Pronouncements.” We completed three asset acquisitions of operating properties during the year ended December 31, 2018 and one asset acquisition of an operating property during the year ended December 31, 2017. We recorded the real estate assets and identifiable below market and in-place leases at their relative fair values based upon methods similar to those used by independent appraisers of income producing properties. The fair value measurements associated with the valuation of these acquired assets represent Level 3 measurements within the fair value hierarchy. See Note 8, "Acquisitions, Dispositions, and Discontinued Operations" for a further discussion about these acquisitions. Financial Instrument Fair Value Disclosures.

Commitments and Contingencies Disclosure [Abstract]
Commitments And Contingencies	15. Commitments and Contingencies Construction Contracts. As of December 31, 2018 , we estimate the additional cost to complete the six consolidated projects currently under construction to be approximately $335.2 million . We expect to fund this amount through a combination of one or more of the following: cash flows generated from operations, draws on our unsecured credit facility or other short-term borrowing, the use of debt and equity offerings under our automatic shelf registration statement, proceeds from property dispositions, equity issued from our 2017 ATM program, other unsecured borrowings or secured mortgages. Litigation . We are subject to various legal proceedings and claims which arise in the ordinary course of business. Matters which arise out of allegations of bodily injury, property damage, and employment practices are generally covered by insurance. While the resolution of these legal proceedings and claims cannot be predicted with certainty, management believes the final outcome of such matters will not have a material adverse effect on our consolidated financial statements. Other Commitments and Contingencies. In the ordinary course of our business, we issue letters of intent indicating a willingness to negotiate for acquisitions, dispositions, or joint ventures and also enter into arrangements contemplating various transactions. Such letters of intent and other arrangements are non-binding as to either party unless and until a definitive contract is entered into by the parties. Even if definitive contracts relating to the purchase or sale of real property are entered into, these contracts generally provide the purchaser with time to evaluate the property and conduct due diligence, during which periods the purchaser will have the ability to terminate the contracts without penalty or forfeiture of any deposit or earnest money. There can be no assurance definitive contracts will be entered into with respect to any matter covered by letters of intent or we will consummate any transaction contemplated by any definitive contract. Furthermore, due diligence periods for real property are frequently extended as needed. An acquisition or sale of real property becomes probable at the time the due diligence period expires and the definitive contract has not been terminated. We are then at risk under a real property acquisition contract, but generally only to the extent of any earnest money deposits associated with the contract, and are obligated to sell under a real property sales contract. At December 31, 2018 , we had $2.9 million in earnest money deposits of which $0.4 million is non-refundable for potential acquisitions of operating properties and land which are included in other assets, net in our consolidated balance sheet. Lease Commitments. At December 31, 2018 , we had long-term leases covering certain land, office facilities and equipment. Rental expense totaled approximately $3.8 million , $4.0 million , and $4.1 million for the years ended December 31, 2018 , 2017 and 2016 , respectively. Minimum annual rental commitments for the years ending December 31, 2019 through 2023 are approximately $2.9 million , $3.0 million , $3.1 million , $2.7 million and $2.6 million , respectively, and approximately $4.5 million in the aggregate thereafter. Investments in Joint Ventures. We have entered into, and may continue in the future to enter into, joint ventures or partnerships (including limited liability companies) through which we own an indirect economic interest in less than 100% of the community or land owned directly by the joint venture or partnership. Our decision whether to hold the entire interest in an apartment community or land ourselves, or to have an indirect interest in the community or land through a joint venture or partnership, is based on a variety of factors and considerations, including: (i) our projection, in some circumstances, that we will achieve higher returns on our invested capital or reduce our risk if a joint venture or partnership vehicle is used; (ii) our desire to diversify our portfolio of investments by market; (iii) our desire at times to preserve our capital resources to maintain liquidity or balance sheet strength; and (iv) the economic and tax terms required by a seller of land or of a community, who may prefer or who may require less payment if the land or community is contributed to a joint venture or partnership. Investments in joint ventures or partnerships are not limited to a specified percentage of our assets. Each joint venture or partnership agreement is individually negotiated, and our ability to operate or dispose of land or of a community in our sole discretion may be limited to varying degrees in our existing joint venture agreements and may be limited to varying degrees depending on the terms of future joint venture agreements. Employment Agreements. At December 31, 2018 , we had employment agreements with 13 of our senior officers, the terms of which expire at various times through August 20, 2019. Such agreements provide for minimum salary levels as well as various incentive compensation arrangements, which are payable based on the attainment of specific goals. The agreements also provide for severance payments plus a gross-up payment if certain situations occur, such as termination without cause or a change of control. In the case of 10 of the agreements, the severance payment equals one times the respective current annual base salary in the case of termination without cause and 2.99 times the respective average annual base salary over the previous three fiscal years in the case of a change of control and a termination of employment or a material adverse change in the scope of their duties. In the case of one agreement, the severance payment equals one times the respective current annual base salary for termination without cause and 2.99 times the greater of current gross income or average gross income over the previous three fiscal years in the case of a change of control. In the case of the other two agreements, the severance payment generally equals 2.99 times the respective average annual compensation over the previous three fiscal years in connection with, among other things, a termination without cause or a change of control, and the officer would be entitled to receive continuation and vesting of certain benefits in the case of such termination.

Summary of Significant Accoun_2

Summary of Significant Accounting Policies and Recent Accounting Pronouncements (Policies)	12 Months Ended
	Dec. 31, 2018
Accounting Policies [Abstract]
Principles Of Consolidation	Principles of Consolidation . Our consolidated financial statements include our accounts and the accounts of other subsidiaries and joint ventures (including partnerships and limited liability companies) over which we have control. All intercompany transactions, balances, and profits have been eliminated in consolidation. Investments acquired or created are evaluated based on the accounting guidance relating to variable interest entities (“VIEs”), which requires the consolidation of VIEs in which we are considered to be the primary beneficiary. If the investment is determined not to be a VIE, then the investment is evaluated for consolidation primarily using a voting interest model. In determining if we have a controlling financial interest, we consider factors such as ownership interests, authority to make decisions, kick-out rights and participating rights.
Acquisitions of Real Estate	Acquisitions of Real Estate . Upon acquisition of real estate, we determine the fair value of tangible and intangible assets, which includes land, buildings (as-if-vacant), furniture and fixtures, the value of in-place leases, including above and below market leases, and acquired liabilities. In estimating these values, we apply methods similar to those used by independent appraisers of income-producing property. Estimates of fair value of acquired debt are based upon interest rates available for the issuance of debt with similar terms and remaining maturities. Depreciation is computed on a straight-line basis over the remaining useful lives of the related tangible assets. The value of in-place leases and above or below market leases is amortized over the estimated average remaining life of leases in place at the time of acquisition; the net carrying value of in-place leases are included in other assets, net and the net carrying value of above or below market leases are included in other liabilities, net in our condensed consolidated balance sheets. During the year ended December 31, 2018 and 2017 , we recognized amortization expense of approximately $9.4 million and $1.3 million , respectively, related to in-place leases. We recognized revenue of approximately $0.2 million related to net below market leases for the year ended December 31, 2018 , and did not recognize any revenue related to net below market leases for the year ended December 31, 2017 . During the year ended December 31, 2018 , the weighted average amortization periods for in-place and net below market leases were approximately seven months and five months , respectively. During the year ended December 31, 2017 , the weighted average amortization period for in-place leases was approximately six months. We did not recognize any revenue or amortization expense related to below market or in-place leases for the year ended December 31, 2016.
Asset Impairment	Asset Impairment . Long-lived assets are reviewed for impairment annually or whenever events or changes in circumstances indicate the carrying amount of an asset may not be recoverable. Impairment may exist if estimated future undiscounted cash flows associated with long-lived assets are not sufficient to recover the carrying value of such assets. We consider projected future undiscounted cash flows, trends, strategic decisions regarding future development plans, and other factors in our assessment of whether impairment conditions exist. While we believe our estimates of future cash flows are reasonable, different assumptions regarding a number of factors, including market rents, economic conditions, and occupancies, could significantly affect these estimates. In estimating fair value, management uses appraisals, management estimates, and discounted cash flow calculations which utilize inputs from a marketplace participant’s perspective. When impairment exists, the long-lived asset is adjusted to its fair value. In addition, we evaluate our equity investments in joint ventures and if we believe there is an other than temporary decline in market value of our investment below our carrying value, we will record an impairment charge. We did not record any impairment charges for the years ended December 31, 2018 , 2017 , or 2016 . The value of our properties under development depends on market conditions, including estimates of the project start date as well as estimates of demand for multifamily communities. We have reviewed market trends and other marketplace information and have incorporated this information as well as our current outlook into the assumptions we use in our impairment analyses. Due to the judgment and assumptions applied in the impairment analyses, it is possible actual results could differ substantially from those estimated. We believe the carrying value of our operating real estate assets, properties under development, and land is currently recoverable. However, if market conditions deteriorate or if changes in our development strategy significantly affect any key assumptions used in our fair value estimates, we may need to take material charges in future periods for impairments related to existing assets. Any such material non-cash charges could have an adverse effect on our consolidated financial position and results of operations.
Cash, Cash Equivalents, and Short-term Investments	Cash and Cash Equivalents . All cash and investments in money market accounts and other highly liquid securities with a maturity of three months or less at the date of purchase are considered to be cash and cash equivalents. We maintain the majority of our cash and cash equivalents at major financial institutions in the United States and deposits with these financial institutions may exceed the amount of insurance provided on such deposits; however, we regularly monitor the financial stability of these financial institutions and believe we are not currently exposed to any significant default risk with respect to these deposits.
Cost Capitalization	Cost Capitalization . Real estate assets are carried at cost plus capitalized carrying charges. Carrying charges are primarily interest and real estate taxes which are capitalized as part of properties under development. Capitalized interest is generally based on the weighted average interest rate of our unsecured debt. Expenditures directly related to the development and improvement of real estate assets are capitalized at cost as land and buildings and improvements. Indirect development costs, including salaries and benefits and other related costs directly attributable to the development of properties, are also capitalized. We begin capitalizing development, construction, and carrying costs when the development of the future real estate asset is probable and activities necessary to prepare the underlying real estate for its intended use have been initiated. All construction and certain carrying costs are capitalized and reported in the balance sheet as properties under development until the apartment homes are substantially completed. As apartment homes within development properties are completed, the total capitalized development cost of each apartment home is transferred from properties under development including land to buildings and improvements. As discussed above, carrying charges are principally interest and real estate taxes capitalized as part of properties under development. Capitalized interest was approximately $13.6 million , $15.2 million , and $18.2 million for the years ended December 31, 2018 , 2017 , and 2016 , respectively. Capitalized real estate taxes were approximately $2.2 million , $2.4 million , and $4.5 million for the years ended December 31, 2018 , 2017 , and 2016 , respectively. Where possible, we stage our construction to allow leasing and occupancy during the construction period, which we believe minimizes the duration of the lease-up period following completion of construction. Our accounting policy related to properties in the development and leasing phase is to expense all operating expenses associated with completed apartment homes. We capitalize renovation and improvement costs we believe extend the economic lives of depreciable property. Capital expenditures subsequent to initial construction are capitalized and depreciated over their estimated useful lives. We also incur expenditures related to renovation and construction of office space we lease and we capitalize these leasehold improvements as furniture, fixtures, equipment and other. We depreciate these costs using the straight-line method over the shorter of the lease term or the useful life of the improvement. Depreciation and amortization is computed over the expected useful lives of depreciable property on a straight-line basis with lives generally as follows: Estimated Useful Life Buildings and improvements 5-35 years Furniture, fixtures, equipment and other 3-20 years Intangible assets/liabilities (in-place leases and below market leases) underlying lease term
Derivative Financial Instruments	Derivative Financial Instruments. Derivative financial instruments are recorded in the consolidated balance sheets at fair value and we do not apply master netting for financial reporting purposes. Accounting for changes in the fair value of derivatives depends on the intended use of the derivative, whether we have elected to designate a derivative in a hedging relationship and apply hedge accounting, and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. Derivatives designated and qualifying as a hedge of the exposure to variability in expected future cash flows or other types of forecasted transactions are cash flow hedges. Hedge accounting generally provides for the matching of the timing of gain or loss recognition on the hedging instrument with the recognition of the changes attributable to the earnings effect of the hedged transactions. We may enter into derivative contracts which are intended to economically hedge certain of our risks, for which hedge accounting does not apply or we elect not to apply hedge accounting.
Discontinued Operations	Discontinued Operations . A property is classified as a discontinued operation when the disposal represents a strategic shift, such as disposal of a major line of business, a major geographical area or a major equity investment. The results of operations for properties sold during the period or classified as held for sale at the end of the period, and meeting the above criteria of discontinued operations, are classified as discontinued operations for all periods presented. The property-specific components of earnings classified as discontinued operations include separately identifiable property-specific revenues, expenses, depreciation, and interest expense, if any. The gain or loss resulting from the eventual disposal of the held for sale properties meeting the criteria of discontinued operations is also classified within discontinued operations. Real estate assets held for sale are measured at the lower of carrying amount or fair value less costs to sell and are presented separately in the accompanying consolidated balance sheets. Subsequent to classification of a property as held for sale, no further depreciation is recorded. Consolidated operating properties sold or classified as held for sale, which do not meet the above criteria of discontinued operations are not included in discontinued operations and the related gains and losses are included in continuing operations. Properties sold by our unconsolidated entities which do not meet the above criteria of discontinued operations are not included in discontinued operations and related gains or losses are reported as a component of equity in income of joint ventures. Gains on sale of real estate are recognized using the full accrual or partial sale methods, as applicable, in accordance with accounting principles generally accepted in the United States of America ("GAAP"), provided various criteria relating to the terms of sale and any subsequent involvement with the real estate sold are satisfied. See Note 8, "Acquisitions, Dispositions, and Discontinued Operations," for discussion of discontinued operations for the year ended December 31, 2016.
Fair Value	Fair Value . For financial assets and liabilities recorded at fair value on a recurring or non-recurring basis, fair value is the price we would receive to sell an asset, or pay to transfer a liability, in an orderly transaction with a market participant at the measurement date. In the absence of such data, fair value is estimated using internal information consistent with what market participants would use in a hypothetical transaction. In determining fair value, observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect our market assumptions; preference is given to observable inputs. These two types of inputs create the following fair value hierarchy: • Level 1: Quoted prices for identical instruments in active markets. • Level 2: Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations whose inputs are observable or whose significant value drivers are observable. • Level 3: Significant inputs to the valuation model are unobservable. Recurring Fair Value Measurements. The following describes the valuation methodologies we use to measure different financial instruments at fair value on a recurring basis: Deferred Compensation Plan Investments. The estimated fair values of investment securities classified as deferred compensation plan investments are based on quoted market prices utilizing public information for the same transactions. Our deferred compensation plan investments are recorded in other assets in our consolidated balance sheets. The inputs associated with the valuation of our recurring deferred compensation plan investments are included in Level 1 of the fair value hierarchy. Derivative Financial Instruments. The estimated fair values of derivative financial instruments are valued using widely accepted valuation techniques including discounted cash flow analysis on the expected cash flows of each derivative. This analysis reflects the contractual terms of the derivatives, including the period to maturity, and uses observable market-based inputs, including interest rate curves and volatility. The fair values of interest rate swaps and caps are estimated using the market-standard methodology of netting the discounted fixed cash payments and the discounted expected variable cash receipts. The variable cash receipts are based on an expectation of interest rates (forward curves) derived from observable market interest rate curves. In addition, credit valuation adjustments, which consider the impact of any credit enhancements to the contracts, are incorporated in the fair values to account for potential nonperformance risk, including our own nonperformance risk and the respective counterparty’s nonperformance risk. The fair value of interest rate caps is determined using the market-standard methodology of discounting the future expected cash receipts which would occur if variable interest rates rise above the strike rate of the caps. The variable interest rates used in the calculation of projected receipts on the cap are based on an expectation of future interest rates derived from observed market interest rate curves and volatilities. Although we have determined the majority of the inputs used to value our derivatives fall within Level 2 of the fair value hierarchy, the credit valuation adjustments associated with our derivatives utilize Level 3 inputs, such as estimates of current credit spreads, to evaluate the likelihood of default. However, we have assessed the significance of the impact of the credit valuation adjustments on the overall valuation of our derivative positions and have determined the credit valuation adjustments are not significant to the overall valuation of our derivatives. As a result, we have determined our derivative valuations in their entirety are classified in Level 2 of the fair value hierarchy. Non-recurring Fair Value Measurements. Certain assets are measured at fair value on a non-recurring basis. These assets are not measured at fair value on an ongoing basis, but are subject to fair value adjustments in certain circumstances. Long-lived assets such as the land, real estate asset, and in-place leases acquired with an operating property are measured in the form of cash received unless otherwise noted. These assets are recorded at fair value if they are impaired using the fair value methodologies used to measure long-lived assets described above at "Asset Impairment." Non-recurring fair value disclosures are not provided for impairments on assets disposed during the period because they are no longer owned by us. The inputs associated with the valuation of long-lived assets are generally included in Level 3 of the fair value hierarchy, unless a quoted price for a similar long-lived asset in an active market exists, at which time they are included in Level 2 of the fair value hierarchy. Financial Instrument Fair Value Disclosures. As of December 31, 2018 and 2017 , the carrying values of cash and cash equivalents, short-term investments, accounts receivable, accounts payable, accrued expenses and distributions payable represent fair value because of the short-term nature of these instruments. The carrying value of restricted cash approximates its fair value based on the nature of our assessment of the ability to recover these amounts. The carrying value of our notes receivable, which are included in other assets, net in our consolidated balance sheets, approximates their fair value. The estimated fair values are based on certain factors, such as market interest rates, terms of the note and credit worthiness of the borrower. These financial instruments utilize Level 3 inputs. In calculating the fair value of our notes payable, interest rate and spread assumptions reflect current credit worthiness and market conditions available for the issuance of notes payable with similar terms and remaining maturities. These financial instruments utilize Level 2 inputs.
Income Recognition	Income Recognition . Our rental revenue is recognized on a straight-line basis and other property revenue is recorded when due from residents and is recognized as it is earned. Other property revenue consists primarily of utility rebillings and administrative, application, and other transactional fees charged to our residents. Our apartment homes are rented to residents on lease terms generally ranging from twelve to fifteen months, with monthly payments due in advance. All other sources of income, including interest and fee and asset management income, are recognized as earned. See Note 3, "Revenues," for further discussion. Operations of multifamily properties acquired are recorded from the date of acquisition in accordance with the acquisition method of accounting. In management’s opinion, due to the number of residents, the types and diversity of submarkets in which our properties operate, and the collection terms, there is no significant concentration of credit risk.
Reclassifications	Reclassifications. Certain reclassifications have been made to amounts in prior period financial statements to conform to the current period presentation. As of December 31, 2018 , we reclassified certain insignificant amounts within investing activities which had no impact on our consolidated statements of cash flows for the years ended December 31, 2017 and 2016 .
Insurance	Insurance . Our primary lines of insurance coverage are property, general liability, health, and workers’ compensation. We believe our insurance coverage adequately insures our properties against the risk of loss attributable to fire, earthquake, hurricane, tornado, flood, and other perils and adequately insures us against other risks. Losses are accrued based upon our estimates of the aggregate liability for claims incurred using certain actuarial assumptions followed in the insurance industry and based on our experience.
Other Assets, Net	Other Assets, Net . Other assets in our consolidated financial statements include investments under deferred compensation plans, deferred financing costs, non-real estate leasehold improvements and equipment, notes receivable, prepaid expenses, and other miscellaneous receivables. Investments under deferred compensation plans are classified as trading securities and are adjusted to fair market value at period end. For a further discussion of our investments under deferred compensation plans, see Note 12, “Share-based Compensation and Benefit Plans.” Deferred financing costs are related to our unsecured credit facility and unsecured short-term borrowing facility, and are amortized no longer than the terms of the related facilities on the straight-line method, which approximates the effective interest method. Corporate leasehold improvements and equipment are depreciated using the straight-line method over the shorter of the expected useful lives or the lease terms which generally range from three to ten years. Notes Receivable. We have one note receivable included in Other assets, net in our consolidated balance sheets, relating to a real estate secured loan to an unaffiliated third party. During 2018, we received payments of approximately $9.5 million in principal and approximately $0.5 million in interest on this note which matures on October 1, 2025. At December 31, 2018 and 2017 , the outstanding note receivable balance was approximately $9.3 million and $18.8 million , respectively, and the weighted average interest rate was approximately 4.0% for each of the years ended December 31, 2018 and 2017 . Interest is recognized over the life of the note and is included in interest and other income in our consolidated statements of income and comprehensive income. We consider a note receivable to be impaired if it is probable we will not collect all contractually due principal and interest, and we do not accrue interest when a note is considered impaired and an allowance is recorded for any principal and previously accrued interest which is not believed to be collectible. All cash receipts on impaired notes are applied to reduce the principal amount of such notes until the principal has been recovered and, thereafter, are recognized as interest income. There were no impairments as of December 31, 2018 or 2017 .
Reportable Segments	Reportable Segments . We operate in a single reportable segment which includes the ownership, management, development, redevelopment, acquisition, and construction of multifamily apartment communities. Each of our operating properties is considered a separate operating segment as each property earns revenues and incurs expenses, individual operating results are reviewed and discrete financial information is available. We do not distinguish or group our consolidated operations based on geography, size or type. Our multifamily apartment communities have similar long-term economic characteristics and provide similar products and services to our residents. Further, all material operations are within the United States and no multifamily apartment community comprises more than 10% of consolidated revenues. As a result, our operating properties are aggregated into a single reportable segment. Our multifamily communities generate rental revenue and other income through the leasing of apartment homes, which comprised approximately 99% of our total property revenues and total non-property income, excluding income on deferred compensation plans, for each of the years ended December 31, 2018 , 2017 , and 2016 .
Restricted Cash	Restricted Cash . Restricted cash consists of escrow deposits held by lenders for property taxes, insurance and replacement reserves, cash required to be segregated for the repayment of residents’ security deposits, and escrowed amounts related to our development and acquisition activities. Substantially all restricted cash is invested in demand and short-term instruments.
Share-based Compensation	Share-based Compensation . Compensation expense associated with share-based awards is recognized in our consolidated statements of income and comprehensive income using the grant-date fair values. Compensation cost for all share-based awards, including options, requires measurement at estimated fair value on the grant date and recognition of compensation expense over the requisite service period for awards expected to vest. The fair value of stock option grants is estimated using the Black-Scholes valuation model. Valuation models require the input of assumptions, including judgments to estimate the expected stock price volatility, expected life, and forfeiture rate. The compensation cost for share-based awards is based on the market value of the shares on the date of grant and is adjusted as actual forfeitures occur.
Use of Estimates	Use of Estimates . In the application of GAAP, management is required to make estimates and assumptions which affect the reported amounts of assets and liabilities at the date of the financial statements, results of operations during the reporting periods, and related disclosures. Our more significant estimates include estimates supporting our impairment analysis related to the carrying values of our real estate assets. These estimates are based on historical experience and other assumptions believed to be reasonable under the circumstances. Future events rarely develop exactly as forecasted, and the best estimates routinely require adjustment.
Recent Accounting Pronouncements	Recent Accounting Pronouncements. In October 2018, the Financial Accounting Standards Board ("FASB") issue d Accounting Standards Update 2018-16 ("ASU 2018-16"), "Derivatives and Hedging (Topic 815): Inclusion of the Secured Overnight Financing Rate (SOFR) Overnight Index Swap (OIS) Rate as a Benchmark Interest Rate for Hedge Accounting Purposes." ASU 2018-16 permits the use of the overnight index swap rate based on the Secured Overnight Financing Rate to be used as a U.S. benchmark interest rate for hedge accounting purposes. ASU 2018-16 is effective for public entities which have already adopted ASU 2017-12 beginning after December 31, 2018. Since we already adopted ASU 2017-12, we adopted ASU 2018-16 as of January 1, 2019 with no impact on our existing hedges. We will consider these changes for qualifying new or redesignated hedging relationships entered into in the future. In August 2018, the FASB issued ASU 2018-15 "Intangibles—Goodwill and Other— Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract." ASU 2018-15 clarifies certain implementation costs relating to a cloud computing arrangement which is considered to be a service contract should be capitalized as if the arrangement was an internal-use software project. The standard also requires costs associated with an implementation to be classified where the fees are recorded in financial statements for such arrangements. ASU 2018-15 is effective for interim and annual periods beginning after December 15, 2019, and early adoption is permitted. This standard may be applied using the prospective transition method which is applicable to service contracts entered, renewed, or materially modified after the effective date or the retrospective transition method which allows us to recognize a cumulative effect adjustment to the opening balance of retained earnings, if any, as of the adoption date. We anticipate adopting ASU 2018-15 as of January 1, 2020, using the retrospective transition method and we do not expect our adoption to have a material impact on our consolidated financial statements. In August 2018, the FASB issued ASU 2018-13 " Fair Value Measurement (Topic 820): Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurement. " ASU 2018-13 removes, modifies, and adds certain fair value disclosure requirements including (i) the removal of disclosures regarding amounts, reasons, and timing for transfers between Levels 1 and 2 as well as descriptions of valuation processes used for Level 3 measurements of the fair value hierarchy; (ii) the modification of disclosures for the timing of liquidation of investee assets; (iii) the clarification of the narrative description of the measurement uncertainty of Level 3 fair value measurements at the reporting date does not need to include sensitivity of future changes; (iv) the addition of disclosures related to changes in unrealized gains and losses in other comprehensive income for recurring Level 3 fair value measurements to also be included in the statement of comprehensive income; and (v) the addition of disclosures for the range and weighted average of significant unobservable inputs. ASU 2018-13 is effective January 1, 2020 for the additional disclosures and early adoption of the removal and amended disclosures is allowed. We expect to adopt ASU 2018-13 as of January 1, 2020 and do not expect the adoption to have a material impact on our consolidated financial statements. In May 2014, the FASB issued ASU 2014-09 "Revenue from Contracts with Customers." ASU 2014-09 prescribes a single, common revenue standard to replace most existing revenue recognition guidance in GAAP, including most industry-specific requirements. The standard outlines a five-step model whereby revenue is recognized as performance obligations within a contract are satisfied. Several ASUs intended to promote a more consistent interpretation and application of the principles outlined in the standard have been issued since the issuance of ASU 2014-09 which modify certain sections of the new revenue recognition standard. We adopted ASU 2014-09 and all related amendments effective January 1, 2018 using the modified retrospective with cumulative effect transition method. This method requires us to recognize the cumulative effect of initially applying the new revenue standard as an adjustment, if any, to the opening balance of retained earnings, which had no impact on our consolidated financial statements upon adoption. See Note 3, "Revenues," for additional disclosures required by the ASU. In February 2016, the FASB issued ASU 2016-02, "Leases." ASU 2016-02 supersedes the current accounting for leases. The new lease standard retains three distinct types of leases which are similar to existing guidance for lessors: operating, sales-type, and financing, and aligns many of the underlying lessor model principles with those in the new revenue standard. For lessees, the new lease standard retains two distinct types of leases, finance and operating; and (i) requires lessees to record a right of use asset and a related liability for the rights and obligations associated with a lease, regardless of lease classification, and recognize lease expense in a manner similar to current accounting and (ii) eliminates most real estate specific lease provisions. We adopted ASU 2016-02 and its related amendments as of January 1, 2019 using the transition practical expedient which allows us to recognize a cumulative-effect adjustment to the opening balance of retained earnings as of the adoption date as well as other elected practical expedients. We have identified our lease commitments and finalized our evaluation on our consolidated financial statements and on our internal accounting processes. Substantially all of our real estate lessor commitments will continue to be accounted for as operating leases and the new leasing standard will not have a material impact on rental revenues. Our lessee operating lease commitments are subject to the standard and recognized as operating lease liabilities and right-of-use assets upon adoption. Our adoption of the new leasing standard will not have a material impact on our consolidated financial statements. Upon our adoption of ASU 2016-02 as of January 1, 2019, we will increase lease liabilities by approximately $16.6 million along with a corresponding right-of-use assets on our consolidated balance sheet, and this ASU will not have any impact on our consolidated statement of income upon adoption.
