The Federal Housing Administration, generally known as "FHA", provides mortgage insurance on loans made by FHA-approved lenders throughout the United States and its territories. FHA insures mortgages on single family and multifamily homes including manufactured homes and hospitals. It is the largest insurer of mortgages in the world, insuring over 34 million properties since its inception in 1934.

Unlike conventional loans that adhere to strict underwriting guidelines, FHA-insured loans require very little cash investment to close a loan. There is more flexibility in calculating household income and payment ratios. The cost of the mortgage insurance is passed along to the homeowner and typically is included in the monthly payment. In most cases, the insurance cost to the homeowner will drop off after five years or when the remaining balance on the loan is 78 percent of the value of the property -whichever is longer.

These loans have extremely flexible underwriting guidelines and allow the borrower to finance up to 97% of the value of the home. The borrower can also finance the upfront mortgage insurance premium.
