Home appraisals in Napa County, by tomorrow

Every city and town in Napa County, same fee, same 24 hours, written and signed by me.

Napa County runs from American Canyon and the city of Napa up the valley through Yountville, St. Helena and Calistoga, with Angwin and Pope Valley in the eastern hills. I value homes here after a death in the family, in divorces and for trusts, and many sit on rural parcels where vines, wells and fire history all shape the number.

What I look at in Napa County

  1. 1

    Sales are thin up valley in Yountville, St. Helena and Calistoga, so I reach further back in time and adjust for acreage, outbuildings and views rather than borrow city sales.

  2. 2

    Since the Atlas and Glass fires, I check fire-hazard maps, whether a home is a rebuild, and how much clearing surrounds it, because hillside buyers here look closely at all three.

  3. 3

    In the city of Napa, older streets around Fuller Park have Victorians and bungalows, and after the 2014 earthquake I ask whether chimneys and foundations were repaired or braced.

Across Napa County

Napa County mixes a valley floor of vineyards, hillside parcels on both ridges, the city of Napa and the lake country to the east. I compare valley-floor homes with valley-floor sales, and Howell Mountain parcels with mountain parcels.

What to photograph

Photograph the view across the vines or the valley, the well and pump house, the septic area, and the cleared ground around the house. In town, show the chimney, the foundation and any original woodwork.

Napa County questions

Can you appraise our parents' place near St. Helena with a few acres of vines?
Yes, when the land is mainly a home site with some planted vines. I value the house, acreage, well and views against other rural Napa Valley sales. A commercial vineyard or a winery needs a specialist, and I'll say so up front.
Can an appraisal lower my Napa County property tax if values dropped this year?
It can support a request. If your home would have sold for less than its assessed value on January 1, the assessor can lower it for that year, and my report shows sales from your part of the valley. Napa County's 2026 appeal deadline is November 30.
When would I get the report for a Napa County home?
Within 24 hours of the moment I have both your payment and your photos, weekends and holidays included. If you're not in a rush, the regular schedule is 5–10 business days at $299 or $449.

“I've prepared desktop appraisals for every purpose on this list. Some situations still call for an in-person appraisal, though, so check with your attorney or tax advisor first to make sure a desktop report is right for yours.”
