The bill aims to expand and preserve permanently affordable homeownership through shared equity models, which restrict resale values to maintain affordability for future low- and moderate-income buyers. It establishes the Lasting Home Affordability Fund within the Treasury Department, authorizing $100 million for fiscal year 2027. This fund will provide grants to state agencies, housing authorities, and community development financial institutions, which will then offer low-interest (up to 3%) construction loans to local governments, nonprofits, and community land trusts. These loans support the construction or rehabilitation of housing units that must remain affordable for low- and moderate-income individuals for at least 99 years, prioritizing areas with high housing costs or displacement risk. Additionally, the bill creates the Lasting Affordability Homeownership Grant Pilot Program under the Department of Housing and Urban Development (HUD), allocating $100 million annually from fiscal years 2027 through 2031. This pilot directly grants funds to eligible entities for purchasing vacant land for development or existing properties for rehabilitation. Homes developed must be sold to households earning up to 80% of the area median income (120% in rural areas) and include mechanisms like ground leases or deed restrictions to ensure permanent affordability through a resale formula. To bolster these efforts, the bill mandates HUD to establish shared equity housing research and awareness programs . This includes conducting research on best practices for community land trusts and other shared equity models, alongside providing technical assistance and capacity building to relevant organizations. HUD is also tasked with launching public awareness and outreach campaigns to educate consumers, lenders, and real estate professionals about the benefits and responsibilities of shared equity homeownership. Finally, the legislation amends federal law to facilitate the use of surplus federal land for affordable housing. It authorizes the conveyance of suitable surplus real property to community land trusts or other shared equity homeownership models. These conveyances will include deed restrictions ensuring the property's perpetual use for affordable housing, with a significant discount (at least 75%) on the market value to reflect the public benefit.
