Fairfax sits in one of California's priciest counties, which makes conforming loan limits especially relevant here. Most Marin properties push past standard conforming limits, but certain neighborhoods and condos still qualify.
The 2026 conforming limit for Marin County is higher than baseline national caps because it's designated a high-cost area. That expanded ceiling creates opportunities most buyers overlook when they assume everything here requires jumbo financing.
Conforming Loans in Fairfax
You need 620 minimum credit for most conforming loans, though 680+ unlocks better pricing. Down payments start at 3% for first-time buyers and 5% for repeat purchasers through certain programs.
Debt-to-income ratios cap at 50% in most cases. Lenders verify two years of steady employment and require full income documentation—W-2s, tax returns, pay stubs.
PMI applies when you put down less than 20%, but it drops off automatically once you hit 78% loan-to-value through payments. No lifetime mortgage insurance like FHA.

Every major lender offers conforming loans because Fannie and Freddie buy them on the secondary market. That universal appeal creates real rate competition—sometimes 0.25% to 0.50% spread between highest and lowest offers.

Condos and smaller single-family homes near downtown occasionally fit conforming limits. Buyers stretching their budget should check these pockets before assuming jumbo is inevitable.
