Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Legal Proceedings The Company is from time to time involved in various disputes, lawsuits, warranty claims, environmental and other matters arising in the ordinary course of business. Management makes assumptions and estimates concerning the likelihood and amount of any potential loss relating to these matters. The Company currently is a party to various legal proceedings, none of which management expects will have a material adverse effect on the Company’s financial position, results of operations, or liquidity. Management accrues a liability for litigation if an unfavorable outcome is determined to be probable and the amount of loss can be reasonably estimated. If an unfavorable outcome is determined to be probable and a range of loss can be reasonably estimated, management accrues the best estimate within the range; however, if no amount within the range is a better estimate than any other, the minimum amount within the range is accrued. Legal fees related to litigation are expensed as incurred. Management does not believe that the ultimate outcome of these matters, either individually or in the aggregate, could have a material adverse effect on the Company’s financial position or results of operations; however, litigation is subject to inherent uncertainties. Under the Company’s leases, tenants are typically obligated to indemnify the Company from and against all liabilities, costs, and expenses imposed upon or asserted against it as owner of the properties due to certain matters relating to the operation of the properties by the tenant. Guarantees In connection with the Company's mezzanine lending activities, the Company has made guarantees to pay portions of certain senior loans of third parties associated with the development projects. As of September 30, 2021, the Company had an outstanding payment guarantee for Interlock Commercial for $37.5 million. The Company has recorded a $1.6 million liability and corresponding addition to notes receivable relating to this guarantee. Commitments The Company has a bonding line of credit for its general contracting construction business and is contingently liable under performance and payment bonds, bonds for cancellation of mechanics liens and defect bonds. Such bonds collectively totaled $2.1 million and $2.4 million as of September 30, 2021 and December 31, 2020, respectively. In addition, as of September 30, 2021, the Company has outstanding a letter of credit for $9.5 million to secure certain performances of the Company's subsidiary construction company under a related party project. On January 7, 2021, the Operating Partnership entered into a $15.0 million standby letter of credit using the available capacity under the credit facility to guarantee the funding of its investment in the Harbor Point Parcel 3 joint venture, which is the developer of T. Rowe Price's new global headquarters. This letter of credit is available for draw down on the revolving credit facility in the event the Company does not meet its equity requirement. Unfunded Loan Commitments The Company has certain commitments related to its notes receivable investments that it may be required to fund in the future. The Company is generally obligated to fund these commitments at the request of the borrower or upon the occurrence of events outside of the Company's direct control. As of September 30, 2021, the Company had two notes receivable with commitments totaling approximately $6.6 million. If commitments are funded in the future, interest will be charged at rates consistent with the existing investments.
