2026 Q2 Single-Family Home Market Update—San Mateo County
The San Mateo single-family home market remained strong in the second quarter of 2026, with both home prices and buyer activity showing positive momentum.
The median sales price reached $2,167,500, up 4% from $2,087,500 in the previous quarter. This continued price growth reflects the ongoing demand for single-family homes in San Mateo.
Homes also continued to sell at a strong premium. The average sale-to-list price ratio was 107%, meaning well-priced homes continued to attract competitive offers and, in many cases, sold above the asking price.
Buyer activity increased significantly during the quarter, with the number of homes sold rising 77% compared with the previous quarter. At the same time, the average days on market decreased to 20 days, indicating that desirable homes were moving relatively quickly.
What This Means for Buyers
Buyers are facing a competitive market, particularly for homes that are well-priced and in desirable locations. While there are opportunities to negotiate, buyers should be prepared to move quickly when the right property comes on the market.
What This Means for Sellers
Strong sale-to-list ratios and shorter marketing times continue to favor well-positioned sellers. Accurate pricing, good presentation, and a thoughtful marketing strategy remain important to attracting multiple offers and maximizing value.
The Bottom Line
San Mateo's single-family market showed stronger activity, rising prices, and continued competition in Q2 2026. With the median price above $2.1 million and homes selling in an average of 20 days, demand remains healthy for desirable properties.
For buyers and sellers, understanding the differences between neighborhoods, property types, and individual homes is more important than simply looking at the overall market numbers.
