Home appraisals in Contra Costa County, by tomorrow

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

Contra Costa County runs from Crockett and Martinez on the Carquinez Strait through Lamorinda and around Mount Diablo, then out Highway 4 to the Delta. I value homes here when someone needs a number fast, after a death, in a divorce or before a buyout, and one week can bring me a Rossmoor condo, an Orinda ranch and a Brentwood two-story with leased solar.

What I look at in Contra Costa County

  1. 1

    In Lamorinda, lots are often steep and irregular, and a flat usable yard can matter as much as the house, so I read the parcel map alongside your yard photos.

  2. 2

    Along the 680 corridor, many Walnut Creek and Pleasant Hill homes are 1950s and 1960s ranches, and I sort them by how much has been updated.

  3. 3

    In Discovery Bay, a home whose dock has a quick run to open Delta water sells differently from one deep inside the channels, so I match water frontage before anything else.

Across Contra Costa County

Contra Costa County holds very different markets: the Richmond flats, Lamorinda behind the tunnel, the 680 corridor under Mount Diablo, and East County's newer tracts and Delta waterfront. I compare your home only with its own corner of the county.

What to photograph

Photograph the Mount Diablo view if you have one, the back yard's slope, and the solar panels with the lease or purchase papers. In Discovery Bay, show the dock, the boat lift and the water view.

Contra Costa County questions

We live out of state, can you appraise Mom's house in Contra Costa County?
Yes. A neighbor or a cleaner can walk the house with a phone, whether it's in Pleasant Hill or Pittsburg, and send me every room, the roof line and the yard. I add county records and recent sales, and every heir gets the same report by email.
How do you value a Rossmoor co-op or condo after a parent passes?
Rossmoor is a 55-plus community whose co-ops, condos and other homes are grouped into separate mutuals, and they don't trade like other Walnut Creek condos. I compare sales inside Rossmoor, matching the mutual, floor plan, view and updates.
When would I get the report for a Contra Costa 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.”
