See how prices, monthly costs, and mortgage rates have moved in San Mateo.
Includes principal, interest, estimated CA property tax (~1.25%), and estimated insurance (~$2,200/yr). HOA fees not included.
The median sale price in San Mateo is $1.71M — up 12% from $1.52M in September 2021. Over that stretch, the median peaked at $1.78M in June 2026 and bottomed at $1.30M in February 2023. That puts today's price about 12% above the area's 5-year average of $1.53M. Each point is the median of a rolling 3-month window of closings, so the curve runs smoother than any single month; the multi-year direction is the signal.
What buyers actually pay has moved more than the sticker price suggests: a typical monthly payment (20% down, principal & interest) is about $8,812 today, up 71% from $5,150 in September 2021. Most of that increase comes from mortgage rates (3.0% then vs. 6.7% now), not prices — at September 2021 rates, today's median would run about $5,789/mo.
Seasonally, the three months ending in August have been the busiest stretch for closings in San Mateo over the past 5 years (about 260 sales in that window on average, vs. 152 for the stretch ending in February), while competition has run hottest in the stretch ending in May (61% of homes selling over asking on average). That's an average across just 5 observations per month, so treat it as a tendency, not a rule.
