The Federal Housing Administration (FHA), also known as the Office of Housing within the Department of Housing and Urban Development (HUD), is a United States government agency founded by President Franklin Delano Roosevelt, established in part by the National Housing Act of 1934. Its primary function is to provide insurance for mortgages originated by private lenders for various types of properties, including single-family homes, multifamily rental properties, hospitals, and residential care facilities. FHA mortgage insurance serves to safeguard these private lenders from financial losses. In the event that a property owner defaults on their mortgage, FHA steps in to compensate the lender for the outstanding principal balance.
