Four ways to pay for a typical home in Sonoma County

For a typical $815,500 home at Freddie Mac's average rate (7.18% as of November 5, 2026) over 30 years. The monthly payment adds principal and interest, the county's property tax, an example homeowners insurance and mortgage insurance when it applies.

  • Cash to close = down payment plus 3% of the price in closing costs (example).
  • Minimum score: FHA requires 580 or higher for the minimum down payment (HUD Handbook 4000.1). * Fannie Mae requires 620 when a loan is underwritten by hand; its automated system has no fixed minimum.

Loan limits

This is a high-cost area, so FHA limits in Sonoma County are above the national floor. The limit is set for the whole metro area (Santa Rosa-Petaluma, CA). If the loan you need is above these amounts, it doesn't fit FHA or it becomes a "jumbo" loan.

VA loans. If you have full VA entitlement, VA doesn't cap the loan amount. If you've used part of your entitlement, the calculation uses the county limit ($897,000 for one unit). VA loan limits (va.gov)

Is there a flood risk?

According to FEMA, in Sonoma County 2.4% of homes (3,971) are in a high-risk flood zone. Of those homes, 31% have NFIP flood insurance.

  • A high-risk zone (Special Flood Hazard Area) has a 1% or greater chance of flooding each year. (44 CFR 59.1)
  • If the home is in that zone and the loan comes from a regulated lender, federal law requires flood insurance for the life of the loan, in communities that take part in the NFIP. (42 U.S.C. 4012a)
  • Most homeowners insurance does not cover flood damage. (FEMA, FloodSmart)

Climate and upkeep

Department of Energy (PNNL), 2021 IECC zones

Sonoma County is climate zone 3C in the home energy code (IECC): marine.

The zone's number says how hot or cold it gets; the letter says how humid: A is moist, B is dry and C is marine.

  • Spring

    • Book the air conditioner's check-up before the heat: ENERGY STAR advises checking the cooling system in the spring, because contractors get busy once summer comes. ENERGY STAR (EPA)
    • Check that the ground slopes away from the house, so water does not collect around the foundation. EPA

  • Summer

    • Seal the air ducts that run through the attic, crawlspace, basement or garage with duct mastic or foil tape, then wrap them in insulation. ENERGY STAR (EPA)
    • Look for drafts at windows and doors: close the window on a piece of paper; if it moves back and forth easily, it needs thicker weather stripping. ENERGY STAR (EPA)

  • Fall

    • Book the heating check-up in the fall. If it runs on gas or oil, the technician should check the connections: faulty ones are a fire hazard. ENERGY STAR (EPA)
    • Clean and repair the roof gutters. EPA

  • Winter

    • Keep indoor humidity below 60 % (ideally between 30 % and 50 %). A humidity meter is inexpensive and sold at hardware stores. EPA
    • Get the house ready for the cold with insulation, caulking and weather stripping, and learn how to keep pipes from freezing. Ready.gov (FEMA)

All year

  • Check the air filter every month, especially in heavy-use months. If it looks dirty, change it; change it at least every 3 months. ENERGY STAR (EPA)
  • Test the smoke alarms every month and replace their batteries at least once a year. USFA (FEMA)

Each task comes from the official page beside it. The spring air-conditioning and fall heating check-ups are the timing ENERGY STAR advises; the rest is a suggested order.
