We launched the Washington Housing Initiative ("WHI") with the Federal City Council in June 2018 as a scalable market-driven model that uses private capital to help address the scarcity of housing for middle income families. The WHI Impact Pool completed fundraising in 2020 with capital commitments totaling $114.4 million, which included a commitment from us of $11.2 million. As of June 30, 2024, our remaining unfunded commitment was $2.9 million. During the second quarter of 2024, we combined our existing impact investing activities, including WHI, with the newly formed LEO Impact Capital ("LEO"), our workforce housing investment management platform. LEO aims to acquire, operate and preserve middle income housing in rapidly growing neighborhoods vulnerable to rising housing costs.
The third-party real estate services revenue, including expense reimbursements, from the JBG Legacy Funds and the WHI Impact Pool and its affiliates was $3.2 million and $7.2 million for the three and six months ended June 30, 2024, and $5.9 million and $10.8 million for the three and six months ended June 30, 2023. As of June 30, 2024 and December 31, 2023, we had receivables from the JBG Legacy Funds and the WHI Impact Pool and its affiliates totaling $2.3 million and $3.5 million for such services.
Commencing in March 2023, in connection with the sale of an 80.0% interest in 4747 Bethesda Avenue in 2023, we leased our corporate offices from an unconsolidated real estate venture and incurred $1.3 million and $2.8 million of rent expense for the three and six months ended June 30, 2024, and $1.6 million and $1.8 million of rent expense for the three and six months ended June 30, 2023,which was included in "General and administrative expense" in our statements of operations.
We have agreements with Building Maintenance Services ("BMS"), an entity in which we have a minor preferred interest, to supervise cleaning, engineering and security services at our properties. We paid BMS $2.2 million and $4.7 million for the three and six months ended June 30, 2024, and $2.3 million and $4.6 million for the three and six months ended June 30, 2023, which was included in "Property operating expenses" in our statements of operations.
