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 during interim periods in 2020 and 2021. The pandemic has led to continuous changes in operational restrictions imposed by governments and other authorities around the world, including federal, state, and local authorities in the United States instituting 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 for certain periods of time. While operations in many areas have been allowed to fully or partially re-open, no assurance can be given that such closures or restrictions will not be reinstituted in the future. The extent of the COVID-19 pandemic’s effect on our business activity will depend on future developments, including the duration and intensity of the pandemic, the timing and effectiveness of COVID-19 vaccines (including against COVID-19 variant strains), the duration of, or the reinstatement of, government measures to mitigate the pandemic or address its effects and the timing and effectiveness of vaccine administration, all of which are uncertain and difficult to predict. Due to the uncertainty surrounding the COVID-19 pandemic, we are not able at this time to estimate the full effect of these factors on our business. 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, 2020.
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. The amounts previously classified as Interest expense on indebtedness and Interest expense on finance leases for the three and six months ended June 30, 2020 in the Condensed Consolidated Statement of Comprehensive Income are now included in a single line item as Interest expense. These reclassifications had no effect on net income or stockholders' equity as previously reported.
Recent Accounting Pronouncements	Recent Accounting Pronouncements Recently Issued Accounting Standards Not Yet Adopted: Reference Rate Reform In March 2020, the Financial Accounting Standards Board ("FASB") issued ASU 2020-04 Reference Rate Reform - Facilitation of the Effects of Reference Rate Reform on Financial Reporting (Topic 848), which became effective on March 12, 2020 and generally can be applied through December 31, 2022. ASU 2020-04 contains practical expedients for reference rate reform related activities that impact debt, leases, derivatives and other contracts. The guidance in ASU 2020-04 is optional and may be elected over time as reference rate reform activities occur. The Company is currently evaluating the effect that adopting this standard may have on its Consolidated Financial Statements. Earnings Per Share In August 2020, the FASB issued ASU 2020-06 an update to ASC Topic 470 and ASC Topic 815, which will be effective beginning January 1, 2022. ASU 2020-06 simplifies the accounting for convertible instruments and removes certain settlement conditions that are required for equity contracts to qualify for the derivative scope exception. This ASU also simplifies diluted earnings per share calculation in certain areas and provides updated disclosure requirements. The Company is currently evaluating the impact of ASU 2020-06 on its consolidated financial statements.
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	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 June 30, 2021 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. The Company defers pre-contract costs when such costs are directly associated with specific anticipated contracts and their recovery is probable.
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.
Legal Proceedings	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.

The Company is currently evaluating the effect that adopting this standard may have on its Consolidated Financial Statements.

Earnings Per Share

In August 2020, the FASB issued ASU 2020-06 an update to ASC Topic 470 and ASC Topic 815, which will be effective beginning January 1, 2022. ASU 2020-06 simplifies the accounting for convertible instruments and removes certain settlement conditions that are required for equity contracts to qualify for the derivative scope exception.

Billings in excess of construction contract costs and estimated earnings represent billings or collections on contracts made in advance of revenue recognized.

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.
