The Federal Housing Administration (FHA) has been insuring lenders against loss on home loans since 1934, and has insured about 35 million homes at a mortgage volume of about $2 trillion. In past years, FHA was often the innovator in testing new mortgage products, but in recent years the private mortgage market has been offering mortgages that appealed to borrowers who otherwise may have sought FHA-insured home loans. As a result, the FHA share of the mortgage market declined.
