Debt Disclosure [Abstract]
Credit Facility	Credit Facility On March 30, 2012, the Company entered into a senior unsecured revolving credit facility in the amount of $40.0 million. The credit facility generally bore interest at a floating rate equal to LIBOR plus 2.50%, subject to adjustment as set forth in the credit agreement, and included an unused commitment fee per annum of (a) 0.2% if the unused balance of the facility was equal to or less than 50% of the available facility and (b) 0.3% if the unused balance of the facility exceeded 50% of the available facility. The credit facility was superseded by the following facility described below. On August 20, 2013, the Company entered into a $220.0 million credit facility, which provided for aggregate revolving loan borrowings of up to $110.0 million and aggregate term loan borrowings of up to $110.0 million. The credit facility contained an "accordion" feature to allow the Company, under certain circumstances, to increase the aggregate commitments under the credit facility to a maximum of $325.0 million. On December 23, 2013, the Company amended the credit facility to decrease the aggregate revolving loan borrowings to $50.0 million and increase the aggregate term loan borrowings to $340.0 million. The term loan component of the credit facility matures in August 2018 and the revolving loan component matures in August 2016. The Company has the option, based upon its corporate leverage, its consolidated net worth and a minimum number of properties in the borrowing base, to have the credit facility priced at either: (a) LIBOR, plus an applicable margin that ranges from 1.50% to 2.75%; or (b) the Base Rate (as defined below), plus an applicable margin that ranges from 0.50% to 1.75%. Base Rate is defined in the credit facility as the greatest of (i) the fluctuating annual rate of interest announced from time to time by the lender as its “prime rate,” (ii) 0.50% above the federal funds effective rate and (iii) 1.00% above the applicable one-month LIBOR. The outstanding balance of the term loan component of the credit facility as of March 31, 2014 and December 31, 2013 was $305.0 million with a weighted average interest rate of 2.18% and 2.19%, respectively, a portion of which is fixed with an interest rate swap. The unused borrowing capacity, based on the value of the borrowing base properties as of March 31, 2014, was $85.0 million. Availability of borrowings is based on a pool of eligible unencumbered real estate assets. The credit facility provides for monthly interest payments for each Base Rate loan and periodic payments for each LIBOR loan, based upon the applicable LIBOR loan period, with all principal outstanding being due on the maturity date. The credit facility may be prepaid at any time, in whole or in part, without premium or penalty. In the event of a default, the lenders have the right to terminate their obligations under the credit facility and to accelerate the payment on any unpaid principal amount of all outstanding loans. The credit facility requires the Company to meet certain financial covenants, including the maintenance of certain financial ratios (such as specified debt to equity and debt service coverage ratios) as well as the maintenance of a minimum net worth. As of March 31, 2014, the Company was in compliance with the debt covenants under the credit facility agreement. As described more fully in Note 18 - Subsequent Events, the credit facility commitments were subsequently increased to $705.0 million.
