The "Pro-Housing Act of 2025" aims to increase affordable housing development through two key programs: a grant and loan pilot program managed by the Department of Housing and Urban Development (HUD) for local housing policy initiatives, and a General Services Administration (GSA) pilot program to transfer unused federal properties to state and local entities for affordable housing development. The HUD program will provide financial support and guidance to entities developing and implementing housing policy plans, while the GSA program will repurpose federal land for mixed-use or affordable housing projects. The bill authorizes \$200 million annually from 2026-2031 for the HUD grant and loan program. The GSA program will end 5 years after the enactment of this section.
