Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation and Summary of Significant Accounting Policies	The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. The consolidated financial statements include the accounts of the Company, its wholly owned subsidiaries and joint ventures in which the Company has a controlling interest. The other partners' equity interests in the consolidated joint ventures are reflected as noncontrolling interests in the consolidated financial statements. The Company also consolidates subsidiaries where the entity is a variable interest entity ("VIE") and it is the primary beneficiary and has the power to direct the activities of the VIE and has the obligation to absorb losses or the right to receive benefits from the VIE that could potentially be significant to the VIE. At September 30, 2015 and December 31, 2014, the Company did not have any VIEs that required consolidation. All significant intercompany transactions and accounts have been eliminated in the accompanying financial statements. The Company consolidates certain joint ventures where it exercises control over major operating and management decisions, or where the Company is the sole general partner and the limited partners do not possess kick-out rights or other substantive participating rights. The equity method of accounting is used for those joint ventures that do not meet the criteria for consolidation and where the Company does not control these joint ventures, but exercises significant influence. The cost method of accounting is used for investments in which the Company does not have significant influence. The investments are reviewed for impairment when indicators of impairment exist. The accompanying unaudited condensed consolidated financial statements reflect all adjustments that are, in the opinion of management, necessary for a fair statement of the results for the interim periods presented. All such adjustments are of a normal recurring nature. The preparation of financial statements in conformity with United States generally accepted accounting principles ("GAAP") requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from these estimates. Operating results for the three and nine months ended September 30, 2015 are not necessarily indicative of the results that may be expected for the year ended December 31, 2015. These financial statements should be read in conjunction with the 2014 annual report on Form 10-K and the audited financial statements included therein and the notes thereto. The balance sheet at December 31, 2014 has been derived from the audited financial statements as of that date but does not include all of the information and footnotes required by GAAP for complete financial statements.
Reclassifications	Reclassifications Certain reclassifications have been made in the 2014 consolidated financial statements to conform to the 2015 classifications with no impact on previously reported net income or equity.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2014-09, "Revenue from Contracts with Customers." This update was initiated in a joint project between the FASB and the International Accounting Standards Board to clarify the principles for recognizing revenue and to develop a common revenue standard for GAAP and International Financial Reporting Standards that would: (1) remove inconsistencies and weaknesses in revenue requirements; (2) provide a more robust framework for addressing revenue issues; (3) improve comparability of revenue recognition practices across entities, industries, jurisdictions, and capital markets; (4) provide more useful information to users of financial statements through improved disclosure requirements; and (5) simplify the preparation of financial statements by reducing the number of requirements to which an entity must refer. The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods and services. This update was initially effective for interim and annual reporting periods beginning after December 15, 2016, and early application was not permitted. In 2015, the FASB deferred the effective date by one year to December 15, 2017 for annual reporting periods beginning after that date with early adoption of the standard permitted, but not before the original effective date of December 15, 2016. The standard allows for either "full retrospective" adoption, meaning the standard is applied to all of the periods presented, or "modified retrospective" adoption, meaning the standard is applied only to the most recent period presented in the financial statements. The Company is currently assessing this guidance for future implementation. In January 2015, the FASB issued ASU No. 2015-01, "Income Statement - Extraordinary and Unusual Items (Subtopic 225-20): Simplifying Income Statement Presentation by Eliminating the Concept of Extraordinary Items," ("ASU 2015-01"). ASU 2015-01 eliminates the concept of an extraordinary item from GAAP. As a result, an entity will no longer be required to segregate extraordinary items from the results of ordinary operations, to separately present an extraordinary item on its income statement, net of tax, after income from continuing operations or to disclose income taxes and earnings-per-share data applicable to an extraordinary item. However, ASU 2015-01 will still retain the presentation and disclosure guidance for items that are unusual in nature and occur infrequently. ASU 2015-01 will be effective for the Company’s fiscal year beginning January 1, 2016 and subsequent interim periods. The adoption of ASU 2015-01 is not expected to have a material effect on the Company’s consolidated financial statements. In February 2015, the FASB issued new consolidation guidance which makes changes to both the variable interest model and the voting model. The new standard specifically eliminates the presumption in the current voting model that a general partner controls a limited partnership or similar entity unless that presumption can be overcome. Generally, only a single limited partner that is able to exercise substantive kick-out rights will consolidate. The new standard will be effective for the Company beginning on January 1, 2016 and early adoption is permitted, including adoption in an interim period. The new standard must be applied using a modified retrospective approach by recording either a cumulative-effect adjustment to equity as of the beginning of the period of adoption or retrospectively to each period presented. The Company is currently evaluating the impact of adopting the new standard on its consolidated financial statements. In April 2015, the FASB issued ASU No. 2015-03, "Simplifying the Presentation of Debt Issuance Costs." This standard amends existing guidance to require the presentation of debt issuance costs in the balance sheet as a deduction from the carrying amount of the related debt liability instead of a deferred charge. It is effective for annual reporting periods beginning after December 15, 2015, with early adoption permitted. Retrospective application of the guidance set forth in this update is required, and as such, once effective, will result in a reclassification of the deferred financing costs currently recorded in receivables and other assets within the consolidated balance sheet to a direct deduction from the carrying amount of debt within total liabilities. In September 2015, the FASB issued ASU No. 2015-16, "Business Combinations (Topic 805): Simplifying the Accounting for Measurement-Period Adjustments," ("ASU 2015-16"). ASU 2015-16 requires an acquirer to recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined. Previously, adjustments to provisional amounts were applied retrospectively. This update requires an entity to present separately on the face of the income statement or disclose in the notes the portion of the amount recorded in current-period earnings by line item that would have been recorded in previous reporting periods if the adjustment to the provisional amounts had been recognized as of the acquisition date. ASU 2015-16 will be effective for the Company’s fiscal year beginning January 1, 2016 and subsequent interim periods. The adoption of ASU 2015-16 is not expected to have a material effect on the Company’s consolidated financial statements.
Fair Values of Financial Instruments	The methods and assumptions used to estimate fair value for each class of financial asset or liability are discussed below: Cash and cash equivalents: The carrying amounts for cash and cash equivalents approximate fair value. Mortgage loan receivable: The carrying amount for mortgage loan receivable approximates fair value. Interest rate swap agreements: The fair value of the interest rate swaps is determined by estimating the expected cash flows over the life of the swap using the mid-market rate and price environment as of the last trading day of the reporting period. This information is considered a Level 2 input as defined by ASC 820. Mortgage notes payable: The fair value of mortgage notes payable is estimated using discounted cash flow analysis, based on the Company's current incremental borrowing rates for similar types of borrowing arrangements. This information is considered a Level 2 input as defined by ASC 820. Notes payable to banks: The fair value of the Company's notes payable to banks is estimated by discounting expected cash flows at current market rates. This information is considered a Level 2 input as defined by ASC 820. Non-financial assets and liabilities recorded at fair value on a non-recurring basis include the following: (1) non-financial assets and liabilities measured at fair value in a business combination; (2) impairment or disposal of long-lived assets measured at fair value; and (3) equity method investments or cost method investments measured at fair value due to an impairment. The fair values assigned to the Company's purchase price allocations utilize Level 2 and Level 3 inputs as defined by ASC 820. The fair value assigned to the long-lived assets for which there was impairment recorded utilize Level 2 inputs as defined by ASC 820.
