| Line of Credit Facility [Line Items] | |||||||||||
| Terms of the unsecured facility | The 2017 Credit Agreement, which applies to both the 2017 Credit Facility and 2017 Term Loan, includes certain restrictions and covenants which limit, among other things the incurrence of additional indebtedness, the incurrence of liens and the disposition of real estate properties (to the extent that: (i) such property dispositions cause the Company to default on any of the financial ratios of the 2017 Credit Agreement (described below), or (ii) the property dispositions are completed while the Company is under an event of default under the 2017 Credit Agreement, unless, under certain circumstances, such disposition is being carried out to cure such default), and which require compliance with financial ratios relating to the maximum leverage ratio (60 percent), the maximum amount of secured indebtedness (40 percent), the minimum amount of fixed charge coverage (1.5 times), the maximum amount of unsecured indebtedness (60 percent), the minimum amount of unencumbered property interest coverage (2.0 times) and certain investment limitations (generally 15 percent of total capitalization). | ||||||||||
| Terms of dividend restriction | The 2017 Credit Agreement contains “change of control” provisions that permit the lenders to declare a default and require the immediate repayment of all outstanding borrowings under the 2017 Credit Facility. These change of control provisions, which have been an event of default under the agreements governing the Company’s revolving credit facilities since June 2000, are triggered if, among other things, a majority of the seats on the Board of Directors (other than vacant seats) become occupied by directors who were neither nominated by the Board Directors nor appointed by a majority of directors nominated by the Board of Directors. Furthermore, the agreements governing the Company's Senior Unsecured Notes include cross-acceleration provisions that would constitute an event of default requiring immediate repayment of the Notes if the change of control provisions under the 2017 Credit Facility are triggered and the lenders declare a default and exercise their rights under the 2017 Credit Facility and accelerate repayment of the outstanding borrowings thereunder. In addition, construction loans secured by two multi-family residential property development projects contain cross-acceleration provisions similar to those in the agreements governing the Notes for defaults by the Company. If these change of control provisions were triggered, the Company could seek a forbearance, waiver or amendment of the change of control provisions from the lenders, however there can be no assurance that the Company would be able to obtain such forbearance, waiver or amendment on acceptable terms or at all. If an event of default has occurred and is continuing, the entire outstanding balance under the 2017 Credit Agreement may (or, in the case of any bankruptcy event of default, shall) become immediately due and payable, and the Company will not make any excess distributions except to enable the General Partner to continue to qualify as a REIT under the IRS Code. | ||||||||||
