Is it a buyer’s market or a seller’s market in Discovery Bay?
Buyers had some room in August. The typical home sold for 97.7% of its list price, so a little under asking. Only one in four sold over list, and more than one in three had cut the price before it sold (Redfin, August 2026).
That’s not a crash. The median barely moved in a year. It does mean a list price here is a starting point, not a done deal, and a seller who starts too high risks joining that 36.5%.
How does Discovery Bay compare with Brentwood, Oakley and Antioch?
Discovery Bay costs the most of the four and sells furthest below list price. Same source and month for every city (Redfin city housing market pages, August 2026, checked September 24, 2026):
| City | Median sale price | Change in a year | Median days on market | Sale to list | Price per sq ft |
|---|---|---|---|---|---|
| Discovery Bay | $791,476 | down 1.1% | 34 | 97.7% | $379 |
| Brentwood | $759,497 | down 2.6% | 30 | 99.2% | $342 |
| Oakley | $675,553 | down 1.1% | 41 | 100.4% | $328 |
| Antioch | $595,106 | up 2.6% | 21 | 101.7% | $331 |
For the bigger picture, C.A.R. put the Contra Costa County median for existing single-family homes at $875,000 in August 2026, up 2.9% from a year earlier (C.A.R., August 2026 home sales and price report, released September 16, 2026). That county figure covers single-family homes only, so it isn’t an apples-to-apples match for Redfin’s all-types Discovery Bay median.
Why can the Discovery Bay median be misleading?
Two reasons: small numbers and the water.
- Small numbers. Only 53 homes sold in August 2026 (Redfin). A few extra deep-water sales, or a few more condos, can push the median up or down without any single home changing value.
- Waterfront vs off-water. A home with a dock on a wide lagoon and a house on a dry street a few blocks away can sell far apart. Redfin’s page doesn’t split them, and we won’t make up a number. The honest way to price one home is recent sales of homes like it, on the same kind of water or street.
What else should I budget besides the price?
A few local line items. Many Discovery Bay homes are in one of nine HOAs the Town lists. Town water and sewer bills went up in 2025, with more increases adopted each July through 2029. And homes inside Reclamation District 800 carry two levee assessments on the tax bill, with the new one starting in fiscal year 2026-27 (Town of Discovery Bay rate sheet dated July 28, 2025; RD 800 board minutes, November 6, 2025). Our separate answer on Discovery Bay HOA fees and monthly costs has the published rates.
When you sell, only the County transfer tax applies, because Discovery Bay is unincorporated: $0.55 per $500 of value (Contra Costa County Clerk-Recorder, checked September 25, 2026). On the August median that’s about $871. For tax questions on a sale, ask a tax professional.
What do mortgage rates mean for Discovery Bay prices?
They’re the wild card. C.A.R. reported 30-year fixed rates averaging 6.67% in August 2026, then above 7.0% in the second week of September based on Mortgage News Daily figures (C.A.R., August 2026 report, released September 16, 2026). Higher rates shrink what a buyer can pay for the same monthly budget. Talk to a lender about your own rate before you set a price range.
