Not every lender offers USDA loans. Many retail banks skip them entirely. You need a lender approved by USDA's Rural Development program.
We work with wholesale lenders who actively close USDA deals in Sonoma County. That matters — USDA has its own underwriting timeline and quirks.
The biggest mistake I see: buyers assume all of Sonoma qualifies. It doesn't. Eligibility maps change, and city-center parcels often get excluded.
Run the address through USDA's eligibility tool before you fall in love with a property. We do this on every deal before wasting anyone's time.
FHA needs 3.5% down. Conventional needs at least 3%. USDA needs nothing. For buyers short on cash, that difference is significant.
