FHA requires 3.5% down at 580 FICO and carries lifetime mortgage insurance. Conventional 97 requires 3% down at 620 FICO with cancellable PMI. For 580–619 FICO: FHA is your only path. For 620+ FICO: run the mortgage insurance math — conventional often wins at 680+ due to cancellable PMI. Both programs detailed by HUD at hud.gov and FHFA at fhfa.gov.

FHA requires 3.5% down for borrowers with 580+ FICO, or 10% down for 500–579 FICO. Conventional loans through Fannie Mae's HomeReady and Freddie Mac's Home Possible programs require as little as 3% down for qualifying first-time homebuyers (620+ FICO). The Conventional 97 product also allows 3% down for borrowers within conforming loan limits.

FHA minimum: 580 FICO for 3.5% down; 500–579 FICO with 10% down (lender overlays often set the practical floor higher at 620). Conventional minimum: 620 FICO for most conforming products. The key practical difference: for borrowers at 580–619 FICO, FHA is typically the only path to 3.5% down. At 620+, the choice turns on mortgage insurance cost.

This is the key long-run cost difference. Conventional PMI cancels automatically once you reach 20% equity (Homeowners Protection Act, 12 U.S.C. § 4902). FHA MIP cannot be canceled for loans with less than 10% down originated after June 3, 2013 — it lasts the life of the loan. For 10%+ down FHA loans originated after 2013, MIP lasts 11 years. Borrowers at 620+ FICO who qualify for either loan should run the lifetime MIP vs PMI math to find the lower total-cost path. Source: HUD Mortgagee Letter 2013-04; CFPB at consumerfinance.gov.
FHA loan limits are set by HUD annually by county, ranging from the national floor ($524,225 for a single-unit home in most areas in 2025) to the ceiling in high-cost markets (up to $1,209,750). Conventional conforming loan limits are set by FHFA annually — the 2025 baseline conforming limit is $806,500 for a single-unit home in most areas, with higher limits in designated high-cost counties. For loan amounts above conforming limits, a jumbo loan (conventional or non-conforming) is required; FHA does not have a jumbo equivalent.

Both FHA and conventional loans allow financing for 2–4 unit properties (duplexes, triplexes, four-plexes) if you occupy one unit as your primary residence. FHA loan limits increase for multi-unit properties — a 4-unit FHA loan in most areas has a higher limit than a single-family FHA loan. Conventional multi-unit loans require meeting the applicable conforming limit. Rental income from the other units can sometimes be used to help qualify for either loan type, subject to lender and GSE guidelines.

FHA mortgage rates are generally slightly lower than conventional rates on the surface because of the government guarantee — but the total cost comparison must include FHA MIP (upfront 1.75% + annual 0.55–0.85%). For borrowers with 620–679 FICO and less than 20% down, FHA often produces a lower payment despite MIP. For borrowers with 680+ FICO, conventional with PMI may be cheaper over the life of the loan because PMI cancels at 20% equity while FHA MIP does not.
