Accounting Policies [Abstract]
Use of Estimates	Use of Estimates The preparation of the condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and accompanying notes. Actual results could materially differ from those estimates.
Real Estate Acquisition Valuation	Real Estate Acquisition Valuation The Company accounts for the acquisition of income-producing real estate or real estate that will be used for the production of income as a business combination. All assets acquired and liabilities assumed in a business combination are measured at their acquisition-date fair values. Acquisition pursuit costs are expensed as incurred and restructuring costs that do not meet the definition of a liability at the acquisition date are expensed in periods subsequent to the acquisition date. During the three and nine months ended September 30, 2012, the Company expensed $0.4 million and $1.2 million, respectively, of acquisition pursuit costs. During the three and nine months ended September 30, 2011, the Company expensed $2.6 million and $3.0 million, respectively, of acquisition pursuit costs. The Company's acquisition pursuit costs are included in general and administrative expense on the accompanying condensed consolidated statements of income. Estimates of the fair values of the tangible assets, identifiable intangibles and assumed liabilities require the Company to make significant assumptions to estimate market lease rates, property-operating expenses, carrying costs during lease-up periods, discount rates, market absorption periods, and the number of years the property will be held for investment. The use of inappropriate assumptions would result in an incorrect valuation of the Company’s acquired tangible assets, identifiable intangibles and assumed liabilities, which would impact the amount of the Company’s net income.
Interest Income	Interest Income The Company's loans receivable are recorded at amortized cost on the accompanying consolidated balance sheets. The amortized cost of a real estate loan receivable is the outstanding unpaid principal balance, net of unamortized costs and fees directly associated with the origination of the loan. The Company reviews on a quarterly basis credit quality indicators such as payment status, changes affecting the underlying real estate collateral (for collateral dependent loans), changes affecting the operations of the facilities securing the loans, and national and regional economic factors. The Company's loans receivable are evaluated for impairment at each balance sheet date. The Company considers a loan to be impaired when, based upon current information and events, it believes that it is probable that the Company will be unable to collect all amounts due under the contractual terms of the loan agreement resulting from the borrower's failure to repay contractual amounts due, the granting of a concession by the Company or the Company's expectation that it will receive assets with fair values less than the carrying value of the loan in satisfaction of the loan. If a loan is considered to be impaired, a reserve is established when the present value of payments expected to be received, observable market prices, the estimated fair value of the collateral (for loans that are dependent on the collateral for repayment) or amounts expected to be received in satisfaction of a loan are lower than the carrying value of that loan. As of September 30, 2012, all of the Company's loans are performing and none are considered to be impaired. Interest income on the Company’s loans receivable is recognized on an accrual basis over the life of the investment using the interest method. Direct loan origination costs are amortized over the term of the loan as an adjustment to interest income. When concerns exist as to the ultimate collection of principal or interest due under a loan, the loan is placed on nonaccrual status and the Company will not recognize interest income until the cash is received, or the loan returns to accrual status. If the Company determines the collection of interest according to the contractual terms of the loan is probable, the Company will resume the accrual of interest.
