FHA insured loans are mortgages that are insured by the Department of Housing and Urban Development — which means the government is essentially guaranteeing it will pay the mortgage if you cannot. FHA insured loans require a much lower down payment on a house than most other financers…usually just 3.5%. Plus, qualifying for an FHA insured loan is often easier than qualifying for a conventional mortgage — making it attractive for homebuyers and homeowners alike.
