What Zillow shows
Zillow's Home Value Index puts the typical Brentwood home at $782,072 as of Sept. 30, 2026, down 0.9% from a year earlier. Zillow says homes go pending in about 37 days.
What it means for buyers and sellers
Redfin rates Brentwood "somewhat competitive" (Compete Score 69). The average home sells for about 1% below list and goes pending in around 38 days; hot homes go about 1% over in around 13 days. Prices are a little softer, but homes are selling faster and in bigger numbers than a year ago, so demand in far East Contra Costa is holding up. See also Antioch.
Redfin figures cover the three months through September 2026 and compare with the same period a year earlier. Zillow's Home Value Index is a typical-home estimate, not a sale price, so the two numbers measure different things and won't match exactly.
