Here is how the program works specifically for buyers, owners, and investors in Sonoma County and the rest of Sonoma County.

Why this fits Sonoma County

Sonoma County is our home market. Fire-zone insurance, well and septic property callouts, and wine-country appraisal knowledge separate lenders that price competitively here from those that don't.

  • Buyers with 620+ credit
  • 3-20% down payments
  • Primary, second-home, and investment purchases
Local considerations
  • Wildfire insurance availability (Zone 2/3)
  • Well and septic property inspections
  • USDA-eligible outlying areas
  • San Francisco, Marin, Alameda, Contra Costa, and Santa Clara counties carry the $1,209,750 high-balance ceiling.
  • Sonoma County sits at a mid-tier limit, so buyers around $900K should check whether high-balance or jumbo prices better.
  • Sacramento and Solano purchases usually fall inside the baseline limit, which is the cheapest pricing tier available.
Real-World Example

How a conventional loan file runs.

Petaluma first-time buyer, 5% down

A dual-income couple buying their first home in Petaluma with limited savings but strong credit and no consumer debt.

Purchase price
$785,000
Down payment
5% ($39,250)
Credit score
748
Mortgage insurance
Removable at 80% LTV

Conventional beat FHA by roughly $180 per month once mortgage insurance was compared, and the PMI drops off entirely once the balance hits 78% of value.

Walnut Creek move-up buyer, 20% down

Selling an existing home and rolling equity into a larger property, closing both transactions in the same week.

Purchase price
$1,180,000
Down payment
20% ($236,000)
Loan type
High-balance conforming
Mortgage insurance
None

Staying at the high-balance conforming limit instead of crossing into jumbo saved a meaningful amount in rate and avoided jumbo reserve requirements.

Examples are illustrative composites of typical files, not offers of credit or guarantees of terms.
