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 its 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 by management 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.

Rowe Price's new global headquarters. This letter of credit was available for draw down on the revolving credit facility in the event the Company did not meet its equity requirement. The letter of credit expired on January 4, 2022 and was not required to be renewed. Unfunded Loan Commitments The Company has certain commitments related to its notes receivable investments that it may be required to fund in the future.

As of December 31, 2023, the Company had six notes receivable with a total of $46.3 million of unfunded commitments. If commitments are funded in the future, interest will be charged at rates consistent with the existing investments.
