Summary of Significant Accounting Policies (Policies)	Jun. 30, 2013
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation Our accompanying unaudited condensed consolidated financial statements include our accounts and those of our operating partnership, or the OP, the wholly-owned subsidiaries of our OP and any consolidated variable interest entities. We operate in an umbrella partnership REIT structure in which subsidiaries of our OP own all of the properties acquired on our behalf. Because we are the sole general partner of our OP and have sole control over its management and major operating decisions (even if additional limited partners are admitted), the accounts of our OP are consolidated. As of June 30, 2013 and December 31, 2012, we owned an approximately 98.89% and 99.93%, respectively, interest in our OP.
Reclassifications	Reclassifications To better present our real estate related balances, we have chosen to break out the details of real estate investments (net) in our balance sheet as opposed to disclosing the details in a footnote. In addition, we have reclassified certain accounts, as further discussed below, in our previously issued balance sheet to conform to current period presentation. In place leases and tenant relationship intangibles are now included in real estate investments (net) as lease intangibles. In addition, accounts and other receivables (net) have been combined with receivables and other assets (net). None of the revised reclassifications reflect corrections of any amounts.
Listing Expenses	Listing Expenses Listing expenses primarily include fees associated with the Listing and share-based compensation expense associated with the long term incentive program, or LTIP, awards that we granted in connection with the Listing.
Noncontrolling Interests	Noncontrolling Interests Net income attributable to noncontrolling interests in our accompanying condensed consolidated income statement relates to both noncontrolling interest reflected within equity and redeemable noncontrolling interest of limited partners reflected outside of equity in our accompanying condensed consolidated balance sheets.
Recently Issued or Adopted Accounting Pronouncements	Recently Issued or Adopted Accounting Pronouncements In January 2013, the Financial Accounting Standards Board, or the FASB, issued Accounting Standards Update, or ASU, 2013-01, Balance Sheet (Topic 210) - Clarifying the Scope of Disclosures about Offsetting Assets and Liabilities, or ASU 2013-01, which clarifies the scope of ASU 2011-11, Balance Sheet (Topic 210) - Disclosures about Offsetting Assets and Liabilities. ASU 2013-01 requires entities to disclose both gross and net information about derivatives, including bifurcated embedded derivatives, repurchase agreements and reverse purchase agreements and securities borrowing and securities lending transactions that are subject to an agreement similar to a master netting arrangement. Entities are required to apply these disclosures for annual reporting periods beginning on or after January 1, 2013, and interim periods within those annual periods. An entity must provide the disclosures required by those amendments retrospectively for all comparative periods presented. We adopted ASU 2011-11 and ASU 2013-01 in the first quarter of fiscal 2013 and have reflected the adoption in our disclosures to our interim condensed consolidated financial statements.
