How to sell a house in Contra Costa County

Owners here choose between a traditional listing and a direct cash sale. A listing can earn a higher price on a house that shows well, though it brings repairs, open houses and a wait on the buyer’s financing.

A cash sale accepts a lower number in return for speed and a firm closing date. That matters if you are relocating, handling an estate, or trying to get ahead of a foreclosure timeline.

1. Tell us about the property. Fill in the form above or call (424) 435-2326.
2. Get your written offer. It arrives within 24 hours, with no cost or obligation.
3. Pick a closing date. Escrow settles the mortgage, taxes and liens from the proceeds.
4. Close and collect your funds. The deed is recorded with the Clerk-Recorder in Martinez.

Our Concord cash-offer process page walks through each stage.

How do Contra Costa County property taxes affect a sale?

California secured property tax is billed in two installments, due November 1 and February 1 and delinquent after 5 p.m. on December 10 and April 10. A late installment carries a penalty. Unpaid taxes are a lien on the house, so on a sale escrow pays them from your proceeds at closing, and you do not have to bring cash to the table.

If you need to pay before you sell, the Tax Collector’s office at 625 Court Street in Martinez takes in-person payments by cash, personal check, money order, cashier’s check or certified check on weekdays from 8 a.m. to 5 p.m. The county’s payment pages note that card payments go through a third-party provider that adds a service fee.

What does it cost to sell a house in Contra Costa County?
