FHA Loan
An FHA loan is a mortgage insured by the Federal Housing Administration. The government insurance protects the lender if the borrower defaults, which lets lenders accept borrowers that a conventional loan might turn away.
The headline advantages are accessibility: a down payment as low as 3.5% with a credit score of 580+ (10% down for scores of 500-579), and more forgiving treatment of past credit problems.
The trade-off is the mortgage insurance premium (MIP): an upfront charge of 1.75% of the loan amount plus an annual premium paid monthly. Unlike the PMI on a conventional loan, MIP on a small-down-payment FHA loan lasts for the life of the loan — the usual way out is refinancing into a conventional loan once you build about 20% home equity. FHA loans also cap the loan size by county and require the home to pass FHA appraisal standards.
