Five counties. Five different real estate stories.
California’s market doesn’t move as one — and the latest numbers across Santa Clara, San Mateo, Alameda, Contra Costa, and San Joaquin show just how different local conditions can be.
Santa Clara — $1.53M | 19 days | -2.2% YoY
San Mateo — $1.69M | 15 days | +2.4% YoY
Alameda — $1.07M | 22 days | +4.1% YoY
Contra Costa — $777K | 29 days | +1.0% YoY
San Joaquin — $547K | 38 days | +2.3% YoY
From pricing and market speed to year-over-year movement, the numbers can look very different from one county to the next.
The takeaway: local context matters. Before making your next real estate move, look beyond the broader California market and understand what’s happening in your specific area.
