The purpose of the direct RHS single family housing loan programs is to provide low- and very low-income people who will live in rural areas with an opportunity to own adequate but modest, decent, safe, and sanitary dwellings and related facilities. The section 502 program offers persons who do not currently own adequate housing, and who cannot obtain other credit, the opportunity to acquire, build, rehabilitate, improve, or relocate dwellings in rural areas. The section 504 program offers loans to very low-income homeowners who cannot obtain other credit to repair or rehabilitate their properties. The section 504 program also offers grants to homeowners age 62 or older who cannot obtain a loan to correct health and safety hazards or to make the unit accessible to household members with disabilities.
