in Foster City, CA
Foster City sits in San Mateo County, which makes USDA loans nearly impossible here. The program targets rural areas, and this peninsula city doesn't qualify. FHA loans work anywhere, which gives them a major advantage in this market.
Both programs offer low barriers to entry for first-time buyers. FHA requires just 3.5% down with credit scores as low as 580. USDA offers zero down but has strict location and income limits that rarely align with Bay Area properties.
FHA loans let you put down 3.5% with a 580 credit score. You'll pay mortgage insurance for the loan's life on most FHA mortgages, which adds roughly 0.85% annually to your payment. These loans cap at $1,249,125 in San Mateo County as of February 2026.
Debt-to-income ratios can stretch to 50% with strong compensating factors. Sellers can contribute up to 6% toward your closing costs. Non-occupant co-borrowers help you qualify without living in the home, which matters when Bay Area prices strain your income.
USDA loans require zero down payment and accept credit scores around 640. The program charges a 1% upfront guarantee fee plus 0.35% annual fee, which costs less than FHA insurance. Income limits cap at 115% of area median, and the property must sit in a USDA-eligible zone.
Foster City doesn't meet USDA's rural or suburban definitions. The program works in places like Pescadero or La Honda in San Mateo County, but not incorporated cities along the peninsula. You'd need to look at properties in different counties entirely.
Local decision guide
Use this comparison to weigh FHA Loans and USDA Loans through local payment fit, eligibility, documentation, and timing before choosing a path in Foster City.

Location eligibility kills USDA for most San Mateo buyers. FHA works on any property type that meets standards, while USDA restricts you to eligible rural zones. The Fed may cut rates later this year, but that helps both programs equally since neither ties to specific rate sheets.
Down payment separates them most. USDA's zero down beats FHA's 3.5%, but you can't use it here anyway. FHA mortgage insurance costs more annually but lets you buy in desirable areas. Income limits don't exist with FHA, while USDA caps your household earnings.
FHA is your only option between these two in Foster City. USDA doesn't cover this area, so comparing them here is theoretical. If you're set on zero down, look at VA loans if you qualify or wait until you save 3.5% for FHA.
Some borrowers search for USDA properties in nearby counties, but commuting from rural areas defeats the purpose of buying near Foster City. Take the FHA route, save your 3.5%, and buy where you actually want to live. Location matters more than saving two percentage points on a down payment.
No. USDA works in unincorporated areas like Pescadero but not cities like Foster City. Check USDA's eligibility map before searching properties.
USDA charges 0.35% annually versus FHA's 0.85%. But USDA's location restrictions make this irrelevant for Foster City buyers.
FHA goes as low as 580, while USDA typically needs 640 minimum. FHA is more flexible with credit challenges.
USDA lets you drop insurance after reaching 80% equity and 11 years. FHA requires insurance for the loan's life on most mortgages.
USDA won't work here. Check VA eligibility if you've served, or consider down payment assistance programs paired with FHA financing.
