USDA is a great program, but it does have some income and location restrictions that are unique to the program.

The Section 502 Guaranteed Loan Program assists approved lenders in providing low- and moderate-income households the opportunity to own adequate, modest, decent, safe and sanitary dwellings as their primary residence in eligible rural areas. Eligible applicants may purchase a dwelling in an eligible rural area with 100% financing. This program helps lenders work with low- and moderate-income households living in rural areas to make homeownership a reality. Providing affordable homeownership opportunities promotes prosperity, which in turn creates thriving communities and improves the quality of life in rural areas.
