This bill mandates that federal agencies, including the Departments of Agriculture, HUD, and Veterans Affairs, along with the GSA and FHFA, issue guidance within 180 days to restrict the sale of federally financed single-family homes. This guidance aims to prevent large institutional investors from acquiring homes that could otherwise be purchased by individual owner-occupants. Specifically, the guidance will require agencies to establish an agency-specific definition of a "large institutional investor" and prevent government programs from facilitating their acquisition of single-family homes. It will also restrict the disposal of federal assets to these investors and actively promote sales of real estate-owned properties to individual owner-occupants through measures like first-look policies and disclosure requirements. However, the guidance must include appropriate, narrowly tailored exceptions, such as for build-to-rent properties that are planned and constructed as rental communities, and other exceptions deemed necessary to support individual owner-occupant housing.
