The Rural Housing Repair Loans and Grants program provides loans and grants to very low-income homeowners to repair, improve, modernize, or to remove health and safety hazards in their rural dwellings. Loans are arranged for up to 20 years at 1 percent interest. Grants may be arranged for recipients who are 62 years of age or older and can be used only to pay for repairs and improvements to remove health and safety hazards. Loan/grant combinations may be arranged for applicants who can repay part of the cost. Very low-income for this program is defined as below 50 percent of the area median income.
