Accounting Policies [Abstract]
Significant Accounting Policies	Significant Accounting Policies Basis of Presentation The accompanying condensed consolidated financial statements were prepared in accordance with U.S. generally accepted accounting principles ("GAAP"). The condensed consolidated financial statements include the financial position and results of operations of the Company and its consolidated subsidiaries, including the Operating Partnership, its wholly-owned subsidiaries, and any interests in variable interest entities ("VIEs") where the Company has been determined to be the primary beneficiary. All significant intercompany transactions and balances have been eliminated in consolidation. In the opinion of management, the condensed consolidated financial statements reflect all adjustments, consisting of normal recurring accruals, which are necessary for the fair presentation of the financial condition and results of operations for the interim periods presented. The accompanying condensed consolidated financial statements were prepared in accordance with the requirements for interim financial information. Accordingly, these interim financial statements have not been audited and exclude certain disclosures required for annual financial statements. Also, the operating results presented for interim periods are not necessarily indicative of the results that may be expected for any other interim period or for the entire year, particularly in light of the novel coronavirus ("COVID-19") pandemic and its effects on the domestic and global economies. The pandemic has led governments and other authorities around the world, including federal, state and local authorities in the United States, to impose measures intended to control its spread, including restrictions on freedom of movement and business operations such as travel bans, border closings, business closures, quarantines and shelter-in-place orders, causing many of the Company’s tenants, particularly in the Company’s retail portfolio, to suspend or limit operations. We expect to continue to experience effects on our business as the impacts from COVID-19 and the related responses continue to develop. These interim financial statements should be read in conjunction with the audited consolidated financial statements of the Company included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2019 . Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported and disclosed. Such estimates are based on management’s historical experience and best judgment after considering past, current, and expected events and economic conditions. Actual results could differ significantly from management’s estimates. Reclassifications Certain items have been reclassified from their prior year classifications to conform to the current year presentation. These reclassifications had no effect on net income or stockholders' equity as previously reported. Recent Accounting Pronouncements Accounting Standards Adopted in 2020 Credit losses In June 2016, the Financial Accounting Standard Board ("FASB") issued ASU 2016-13, Financial Instruments - Credit Losses - Measurement of Credit Losses on Financial Instruments (Topic 326). ASU 2016-13 significantly changes how entities will measure credit losses for most financial assets and certain other instruments that are not measured at fair value through net income. The guidance replaces the "incurred loss" approach under previous guidance with an "expected loss" model for instruments measured at amortized cost, such as the Company's notes receivable, construction receivables, and off-balance sheet credit exposures. The amendment requires entities to consider a broader range of information to estimate expected credit losses, which may result in earlier recognition of losses. The Company adopted the new standard on January 1, 2020, using the modified retrospective transition method and recorded a noncash cumulative effect adjustment to record a reduction to retained earnings of $3.0 million , $2.8 million of which relates to the Company's mezzanine loans and $0.2 million of which relates to the Company's construction accounts receivable. See Note 6—Notes Receivable and Current Expected Credit Losses, for more information. Fair Value Measurements In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement - Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement (Topic 820). The ASU is part of the FASB's disclosure framework project to improve the effectiveness of disclosures in the notes to financial statements by facilitating clear communication of the information required by generally accepted accounting principles. The ASU modifies disclosure requirements on fair value measurements in Topic 820. The Company adopted the new standard on January 1, 2020. Adoption of the ASU did not have a material impact on disclosures in the Company's consolidated financial statements. See Note 12—Fair Value of Financial Instruments, for more information on the Company's presentation of the fair value of financial instruments. Pending Accounting Guidance Lease Modification Accounting Q&A In April 2020, the FASB staff issued a question and answer document (the "Lease Modification Q&A") focused on the application of lease accounting guidance to lease concessions provided as a result of the COVID-19 pandemic. Under existing lease guidance, the Company would have to determine, on a lease by lease basis, if a lease concession was the result of a new arrangement reached with the tenant (treated within the lease modification accounting framework) or if a lease concession was under the enforceable rights and obligations within the existing lease agreement (precluded from applying the lease modification accounting framework). The Lease Modification Q&A allows lessors, if certain criteria have been met, to bypass the lease by lease analysis, and instead elect to either apply the lease modification accounting framework or not, with such election applied consistently to leases with similar characteristics and similar circumstances. The Company is evaluating the Lease Modification Q&A. Other Accounting Policies See the Company's Annual Report on Form 10-K for the year ended December 31, 2019 for a description of other accounting principles upon which basis the accompanying consolidated financial statements were prepared.

Segments

Segment Reporting [Abstract]
Segments	Segments Net operating income (segment revenues minus segment expenses) is the measure used by the Company’s chief operating decision-maker to assess segment performance. Net operating income is not a measure of operating income or cash flows from operating activities as measured by GAAP and is not indicative of cash available to fund cash needs. As a result, net operating income should not be considered an alternative to cash flows as a measure of liquidity. Not all companies calculate net operating income in the same manner. The Company considers net operating income to be an appropriate supplemental measure to net income because it assists both investors and management in understanding the core operations of the Company’s real estate and construction businesses. Net operating income of the Company’s reportable segments for the three months ended March 31, 2020 and 2019 was as follows (in thousands): Three Months Ended March 31, 2020 2019 Office real estate Rental revenues $ 10,192 $ 5,556 Rental expenses 2,546 1,486 Real estate taxes 1,146 526 Segment net operating income 6,500 3,544 Retail real estate Rental revenues 20,411 17,257 Rental expenses 3,020 2,600 Real estate taxes 2,166 1,811 Segment net operating income 15,225 12,846 Multifamily residential real estate Rental revenues 11,686 8,096 Rental expenses 3,809 2,639 Real estate taxes 1,021 791 Segment net operating income 6,856 4,666 General contracting and real estate services Segment revenues 47,268 17,036 Segment expenses 45,550 16,286 Segment gross profit 1,718 750 Net operating income $ 30,299 $ 21,806 Rental expenses represent costs directly associated with the operation and management of the Company’s real estate properties. Rental expenses include asset management expenses, property management fees, repairs and maintenance, insurance, and utilities. General contracting and real estate services revenues for the three months ended March 31, 2020 and 2019 exclude revenue related to intercompany construction contracts of $13.1 million and $30.2 million , respectively, as it is eliminated in consolidation. General contracting and real estate services expenses for the three months ended March 31, 2020 and 2019 exclude expenses related to intercompany construction contracts of $13.0 million and $29.9 million , respectively. The following table reconciles net operating income to net income, the most directly comparable GAAP measure, for the three months ended March 31, 2020 and 2019 (in thousands): Three Months Ended March 31, 2020 2019 Net operating income $ 30,299 $ 21,806 Depreciation and amortization (14,279 ) (9,904 ) Amortization of right-of-use assets - finance leases (147 ) — General and administrative expenses (3,793 ) (3,401 ) Acquisition, development and other pursuit costs (27 ) (400 ) Impairment charges (158 ) — Interest income 7,226 5,319 Interest expense on indebtedness (7,959 ) (5,886 ) Interest expense on finance leases (229 ) — Equity in income of unconsolidated real estate entities — 273 Change in fair value of interest rate derivatives (1,736 ) (1,463 ) Provision for unrealized credit losses (377 ) — Other income (expense), net 58 60 Income tax benefit 257 110 Net income $ 9,135 $ 6,514

Leases [Abstract]
Leases	Leases Lessee Disclosures As a lessee, the Company has eight ground leases on seven properties with initial terms that range from 5 to 65 years and options to extend up to an additional 70 years in certain cases. The exercise of lease renewal options is at the Company's sole discretion. The depreciable life of assets and leasehold improvements are limited by the expected lease term. Six of these leases have been classified as operating leases and two of these leases have been classified as finance leases. The Company's lease agreements do not contain any residual value guarantees or material restrictive covenants.

Interest on the mezzanine loans is accrued and funded utilizing the interest reserves for each loan, which are components of the respective maximum loan commitments, and such accrued interest is added to the loan receivable balances. The Company recognized interest income for the three months ended March 31, 2020 and 2019 as follows (in thousands): Three Months Ended March 31, Development Project 2020 2019 1405 Point $ — $ 610 The Residences at Annapolis Junction 2,468 (a) 2,024 (b) North Decatur Square — 638 Delray Plaza 489 310 Nexton Square 391 510 Interlock Commercial 3,017 (a) 743 Solis Apartments at Interlock 838 463 Total mezzanine 7,203 5,298 Other interest income 23 21 Total interest income $ 7,226 $ 5,319 ________________________________________ (a) Includes partial recognition of interest income related to an exit fee that is due upon repayment of the loan. (b) Includes amortization of the $5.0 million loan modification fee paid by the borrower in November 2018. Delray Plaza On March 3, 2020, the Delray Plaza loan was modified to increase the maximum amount of the loan to $17.0 million , with $2.0 million of additional funds borrowed at an interest rate of 6% in order to fund final development activities. The borrower pledged 125,832 Class A Units as additional collateral for this loan. Current Expected Credit Losses The Company is exposed to credit losses primarily through its mezzanine lending activities. As of March 31, 2020, the Company had five mezzanine loans, all of which are secured by second liens on development projects in various stages of completion or lease-up. Each of these projects is subject to a loan that is senior to the Company’s mezzanine loan. Interest on these loans is paid in kind and is generally not expected to be paid until a sale of the project after completion of the development. The Company's management performs a quarterly analysis of the loan portfolio to determine the risk of credit loss based on the progress of development activities including leasing activities, projected development costs, and current and projected mezzanine and senior construction loan balances. The Company estimates future losses on its notes receivable using risk ratings that correspond to probabilities of default and loss given default. The Company's risk ratings are as follows: • Pass: loans in this category are adequately collateralized by a development project with conditions materially consistent with the Company's underwriting assumptions. • Special Mention: loans in this category show signs that the economic performance of the project may suffer as a result of slower-than-expected leasing activity or an extended development or marketing timeline. Loans in this category warrant increased monitoring by management. • Substandard: loans in this category may not be fully collected by the Company unless remediation actions are taken. Remediation actions may include obtaining additional collateral or assisting the borrower with asset management activities to prepare the project for sale. The Company may also consider placing the loan on non-accrual status if it does not believe that additional interest accruals will ultimately be collected. On a quarterly basis, the Company compares the risk inherent in its loans to industry loan loss data experienced during past business cycles. The Company updated the risk ratings for each of its notes receivable during the three months ended March 31, 2020. The Company obtained industry loan loss data relative to these risk ratings as of December 31, 2019. The following table presents amortized cost basis of the portfolio by year of origination and risk rating as of March 31, 2020 (in thousands): Year of Origination Risk Ratings 2020 2019 2018 2017 2016 Total Pass $ — $ — $ 120,495 $ — $ — $ 120,495 Special Mention — — — — — — Substandard — — — 14,839 42,150 56,989 Total amortized cost basis $ — $ — $ 120,495 $ 14,839 $ 42,150 $ 177,484 As of December 31, 2019 , there was no allowance for loan losses.

Non-employee director restricted stock awards vest either immediately upon grant or over a period of one year , subject to continued service to the Company. Unvested restricted stock awards are entitled to receive dividends from their grant date. During the three months ended March 31, 2020 , the Company issued performance-based awards in the form of restricted stock units to certain employees. The performance period for these awards is three years , with a required two -year service period immediately following the expiration of the performance period in order to fully vest.

Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments	Fair Value of Financial Instruments Fair value measurements are based on assumptions that market participants would use in pricing an asset or a liability. The hierarchy for inputs used in measuring fair value is as follows: Level 1 — quoted prices in active markets for identical assets or liabilities Level 2 — observable inputs other than quoted prices in active markets for identical assets and liabilities Level 3 — unobservable inputs Except as disclosed below, the carrying amounts of the Company’s financial instruments approximate their fair values. Financial assets and liabilities whose fair values are measured on a recurring basis using Level 2 inputs consist of interest rate swaps and caps. The Company measures the fair values of these assets and liabilities based on prices provided by independent market participants that are based on observable inputs using market-based valuation techniques. Financial assets and liabilities whose fair values are not measured at fair value but for which the fair value is disclosed include the Company's notes receivable and indebtedness. The fair value is estimated by discounting the future cash flows of each instrument at estimated market rates consistent with the maturity, credit characteristics, and other terms of the arrangements, which are Level 3 inputs under the fair value hierarchy. In certain cases, the inputs used to estimate the fair value may fall into different levels of the fair value hierarchy. For disclosure purposes, the level within which the fair value measurement is categorized is based on the lowest level input that is significant to the fair value measurement. Considerable judgment is used to estimate the fair value of financial instruments. The estimates of fair value presented herein are not necessarily indicative of the amounts that could be realized upon disposition of the financial instruments. The carrying amounts and fair values of the Company’s financial instruments as of March 31, 2020 and December 31, 2019 were as follows (in thousands): March 31, 2020 December 31, 2019 Carrying Value Fair Value Carrying Value Fair Value Indebtedness $ 1,006,617 $ 1,009,377 $ 950,537 $ 958,421 Notes receivable 178,652 173,422 159,371 159,371 Interest rate swap liabilities 16,431 16,431 7,720 7,720 Interest rate swap and cap assets 143 143 25 25

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Legal Proceedings The Company is from time to time involved in various disputes, lawsuits, warranty claims, environmental and other matters arising in the ordinary course of business. Management makes assumptions and estimates concerning the likelihood and amount of any potential loss relating to these matters. The Company currently is a party to various legal proceedings, none of which management expects will have a material adverse effect on the Company’s financial position, results of operations, or liquidity. Management accrues a liability for litigation if an unfavorable outcome is determined to be probable and the amount of loss can be reasonably estimated. If an unfavorable outcome is determined to be probable and a range of loss can be reasonably estimated, management accrues the best estimate within the range; however, if no amount within the range is a better estimate than any other, the minimum amount within the range is accrued. Legal fees related to litigation are expensed as incurred. Management does not believe that the ultimate outcome of these matters, either individually or in the aggregate, could have a material adverse effect on the Company’s financial position or results of operations; however, litigation is subject to inherent uncertainties. Under the Company’s leases, tenants are typically obligated to indemnify the Company from and against all liabilities, costs, and expenses imposed upon or asserted against it as owner of the properties due to certain matters relating to the operation of the properties by the tenant. Guarantees In connection with the Company's mezzanine lending activities, the Company has made guarantees to pay portions of certain senior loans of third parties associated with the development projects. The following table summarizes the guarantees made by the Company as of March 31, 2020 (in thousands): Development project Payment guarantee amount The Residences at Annapolis Junction $ 8,300 Delray Plaza 5,180 Nexton Square 12,600 Interlock Commercial (1) 30,654 Total $ 56,734 ________________________________________ (1) In May 2020, the borrower for the Interlock Commercial loan modified the senior construction loan on the project. As part of this modification, the Company agreed to increase its payment guaranty for this senior loan to $34.3 million . Commitments The Company has a bonding line of credit for its general contracting construction business and is contingently liable under performance and payment bonds, bonds for cancellation of mechanics liens and defect bonds. Such bonds collectively totaled $4.0 million and $4.3 million as of March 31, 2020 and December 31, 2019 , respectively. In addition, as of March 31, 2020 , the Company has outstanding a letter of credit for $9.5 million to secure certain performances of the Company's subsidiary construction company under a related party project.

Subsequent Events [Abstract]
Subsequent Events	Subsequent Events The Company has evaluated subsequent events through the date on which this Form 10-Q was filed, the date on which these financial statements were issued, and identified the items below for discussion. COVID-19 The Company is closely monitoring the impact of the COVID-19 pandemic on all aspects of its business, including the impact on its tenants, rental revenue, business partners, and construction timelines. The Company has proactively deferred the previously announced Chronicle Mill, Southern Post, and Ten Tryon development projects in order to provide additional balance sheet flexibility until economic conditions stabilize, each of which had previously been scheduled to commence during the second quarter of 2020. The extent of the pandemic’s effect on the Company’s operational and financial performance will depend on future developments, including the duration, spread and intensity of the pandemic and the duration of government measures to mitigate the pandemic, all of which are uncertain and difficult to predict. As a result of the pandemic, the Company could experience material impacts on its business, results of operations and cash flows in the remainder of 2020. The Coronavirus Aid, Relief and Economic Security Act, or the CARES Act, was enacted on March 27, 2020 in the United States. The Company continues to assess the potential impacts of this legislation, including the eligibility of the Company and its tenants for funding under programs designed to provide financial assistance to U.S. businesses. The Company has availed itself of the option to defer payment of the employer share of Social Security payroll taxes that would otherwise have been owed from the date of enactment of the CARES Act through December 31, 2020. Leases Due to the business disruptions and challenges severely affecting the global economy caused by the COVID-19 pandemic, the Company is working with tenants to provide rent deferrals, where warranted. See Note 2—Summary of Significant Accounting Policies for a discussion of additional guidance issued by the FASB regarding accounting for lease concessions. Real Estate dispositions On April 8, 2020, the Company’s agreement to sell a portfolio of seven retail properties for $106.5 million , as described in Note 5, was terminated. Notes Receivable Effective April 1, 2020, the Company placed the mezzanine loans for Delray Plaza and The Residences at Annapolis Junction on non-accrual status. These loans have accrued interest up to the point that the outstanding debt is approximately equal to the net realizable value of the underlying development projects. In May 2020, the Company modified the Interlock Commercial loan to allow for an additional $7.0 million of loan funding for purposes of building townhome units as an additional phase of this development project. The borrower also modified the senior construction loan on the project. As part of this modification, the Company agreed to increase its payment guaranty for this senior loan to $34.3 million . Indebtedness In April 2020, the Company borrowed $4.9 million on its construction loans to fund development activities. In April 2020, the Company proactively obtained a waiver from the lender for the Premier Retail/Apartments property wherein the Company will not have to meet the minimum debt service coverage requirement for the period ending June 30, 2020. The Company also proactively obtained a waiver from the lender for the 249 Central Park, Fountain Plaza Retail, and South Retail properties wherein the Company will not have to meet the minimum debt service coverage requirement for the periods ending June 30, 2020 and December 31, 2020. Equity On April 2, 2020, the Company paid cash dividends of $12.4 million to common stockholders, and the Operating Partnership paid cash distributions of $4.7 million to holders of Class A Units other than the Company. On April 15, 2020, the Company paid cash dividends of $1.1 million to holders of shares of Series A Preferred Stock. On April 30, 2020, the Company announced that its Board of Directors declared a cash dividend of $0.421875 per share of Series A Preferred Stock for the second quarter of 2020. The dividend will be payable in cash on July 15, 2020 to stockholders of record on July 1, 2020. On April 30, 2020, the Company announced that its Board of Directors suspended quarterly cash dividends on common stock and cash distributions on Class A Units.

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying condensed consolidated financial statements were prepared in accordance with U.S. generally accepted accounting principles ("GAAP"). The condensed consolidated financial statements include the financial position and results of operations of the Company and its consolidated subsidiaries, including the Operating Partnership, its wholly-owned subsidiaries, and any interests in variable interest entities ("VIEs") where the Company has been determined to be the primary beneficiary. All significant intercompany transactions and balances have been eliminated in consolidation. In the opinion of management, the condensed consolidated financial statements reflect all adjustments, consisting of normal recurring accruals, which are necessary for the fair presentation of the financial condition and results of operations for the interim periods presented. The accompanying condensed consolidated financial statements were prepared in accordance with the requirements for interim financial information. Accordingly, these interim financial statements have not been audited and exclude certain disclosures required for annual financial statements. Also, the operating results presented for interim periods are not necessarily indicative of the results that may be expected for any other interim period or for the entire year, particularly in light of the novel coronavirus ("COVID-19") pandemic and its effects on the domestic and global economies. The pandemic has led governments and other authorities around the world, including federal, state and local authorities in the United States, to impose measures intended to control its spread, including restrictions on freedom of movement and business operations such as travel bans, border closings, business closures, quarantines and shelter-in-place orders, causing many of the Company’s tenants, particularly in the Company’s retail portfolio, to suspend or limit operations. We expect to continue to experience effects on our business as the impacts from COVID-19 and the related responses continue to develop. These interim financial statements should be read in conjunction with the audited consolidated financial statements of the Company included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2019 .
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported and disclosed. Such estimates are based on management’s historical experience and best judgment after considering past, current, and expected events and economic conditions. Actual results could differ significantly from management’s estimates.
Reclassification	Reclassifications Certain items have been reclassified from their prior year classifications to conform to the current year presentation. These reclassifications had no effect on net income or stockholders' equity as previously reported.
Recent Accounting Pronouncements	Recent Accounting Pronouncements Accounting Standards Adopted in 2020 Credit losses In June 2016, the Financial Accounting Standard Board ("FASB") issued ASU 2016-13, Financial Instruments - Credit Losses - Measurement of Credit Losses on Financial Instruments (Topic 326). ASU 2016-13 significantly changes how entities will measure credit losses for most financial assets and certain other instruments that are not measured at fair value through net income. The guidance replaces the "incurred loss" approach under previous guidance with an "expected loss" model for instruments measured at amortized cost, such as the Company's notes receivable, construction receivables, and off-balance sheet credit exposures. The amendment requires entities to consider a broader range of information to estimate expected credit losses, which may result in earlier recognition of losses. The Company adopted the new standard on January 1, 2020, using the modified retrospective transition method and recorded a noncash cumulative effect adjustment to record a reduction to retained earnings of $3.0 million , $2.8 million of which relates to the Company's mezzanine loans and $0.2 million of which relates to the Company's construction accounts receivable. See Note 6—Notes Receivable and Current Expected Credit Losses, for more information. Fair Value Measurements In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement - Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement (Topic 820). The ASU is part of the FASB's disclosure framework project to improve the effectiveness of disclosures in the notes to financial statements by facilitating clear communication of the information required by generally accepted accounting principles. The ASU modifies disclosure requirements on fair value measurements in Topic 820. The Company adopted the new standard on January 1, 2020. Adoption of the ASU did not have a material impact on disclosures in the Company's consolidated financial statements. See Note 12—Fair Value of Financial Instruments, for more information on the Company's presentation of the fair value of financial instruments. Pending Accounting Guidance Lease Modification Accounting Q&A In April 2020, the FASB staff issued a question and answer document (the "Lease Modification Q&A") focused on the application of lease accounting guidance to lease concessions provided as a result of the COVID-19 pandemic. Under existing lease guidance, the Company would have to determine, on a lease by lease basis, if a lease concession was the result of a new arrangement reached with the tenant (treated within the lease modification accounting framework) or if a lease concession was under the enforceable rights and obligations within the existing lease agreement (precluded from applying the lease modification accounting framework). The Lease Modification Q&A allows lessors, if certain criteria have been met, to bypass the lease by lease analysis, and instead elect to either apply the lease modification accounting framework or not, with such election applied consistently to leases with similar characteristics and similar circumstances. The Company is evaluating the Lease Modification Q&A.
Segments	Segments Net operating income (segment revenues minus segment expenses) is the measure used by the Company’s chief operating decision-maker to assess segment performance. Net operating income is not a measure of operating income or cash flows from operating activities as measured by GAAP and is not indicative of cash available to fund cash needs. As a result, net operating income should not be considered an alternative to cash flows as a measure of liquidity. Not all companies calculate net operating income in the same manner. The Company considers net operating income to be an appropriate supplemental measure to net income because it assists both investors and management in understanding the core operations of the Company’s real estate and construction businesses.
Construction Contracts	The Company defers pre-contract costs when such costs are directly associated with specific anticipated contracts and their recovery is probable.Construction Contracts Construction contract costs and estimated earnings in excess of billings represent reimbursable costs and amounts earned under contracts in progress as of the balance sheet date. Such amounts become billable according to contract terms, which usually consider the passage of time, achievement of certain milestones, or completion of the project. The Company expects to bill and collect substantially all construction contract costs and estimated earnings in excess of billings as of March 31, 2020 during the next twelve months. Billings in excess of construction contract costs and estimated earnings represent billings or collections on contracts made in advance of revenue recognized.
Derivative Financial Instruments	Derivative Financial Instruments The Company enters into interest rate derivative contracts to manage exposure to interest rate risks. The Company does not use derivative financial instruments for trading or speculative purposes. Derivative financial instruments are recognized at fair value and presented within other assets and other liabilities in the condensed consolidated balance sheets. Gains and losses resulting from changes in the fair value of derivatives that are neither designated nor qualify as hedging instruments are recognized within the change in fair value of interest rate derivatives in the condensed consolidated statements of comprehensive income. For derivatives that qualify as cash flow hedges, the gain or loss is reported as a component of other comprehensive income (loss) and reclassified into earnings in the periods during which the hedged forecasted transaction affects earnings.
Fair Value of Financial Instruments	Fair Value of Financial Instruments Fair value measurements are based on assumptions that market participants would use in pricing an asset or a liability. The hierarchy for inputs used in measuring fair value is as follows: Level 1 — quoted prices in active markets for identical assets or liabilities Level 2 — observable inputs other than quoted prices in active markets for identical assets and liabilities Level 3 — unobservable inputs Except as disclosed below, the carrying amounts of the Company’s financial instruments approximate their fair values. Financial assets and liabilities whose fair values are measured on a recurring basis using Level 2 inputs consist of interest rate swaps and caps. The Company measures the fair values of these assets and liabilities based on prices provided by independent market participants that are based on observable inputs using market-based valuation techniques. Financial assets and liabilities whose fair values are not measured at fair value but for which the fair value is disclosed include the Company's notes receivable and indebtedness. The fair value is estimated by discounting the future cash flows of each instrument at estimated market rates consistent with the maturity, credit characteristics, and other terms of the arrangements, which are Level 3 inputs under the fair value hierarchy. In certain cases, the inputs used to estimate the fair value may fall into different levels of the fair value hierarchy. For disclosure purposes, the level within which the fair value measurement is categorized is based on the lowest level input that is significant to the fair value measurement. Considerable judgment is used to estimate the fair value of financial instruments. The estimates of fair value presented herein are not necessarily indicative of the amounts that could be realized upon disposition of the financial instruments.
