Data through September 2026
See how prices, monthly costs, and mortgage rates have moved in Foster City.
Includes principal, interest, estimated CA property tax (~1.25%), and estimated insurance (~$2,200/yr). HOA fees not included.
The median sale price in Foster City is $1.29M — down 17% from $1.55M in October 2021. Over that stretch, the median peaked at $2.05M in June 2024 and bottomed at $1.29M in September 2026. That puts today's price about 18% below the area's 5-year average of $1.58M. 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 $6,870 today, up 29% from $5,322 in October 2021. Most of that increase comes from mortgage rates (3.1% then vs. 7.0% now), not prices — at October 2021 rates, today's median would run about $4,419/mo.
Seasonally, the three months ending in October have been the busiest stretch for closings in Foster City over the past 5 years (about 71 sales in that window on average, vs. 46 for the stretch ending in February), while competition has run hottest in the stretch ending in May (72% 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.
Foster City is balanced but competition is picking up. It remains a reasonable environment for buyers, though acting decisively on well-priced homes is becoming more important.
At $1.29M, Foster City's median sits about 27% below the Bay Area average of $1.77M. That average is skewed high by ultra-premium peninsula enclaves like Atherton and Woodside, so a more useful frame is that Foster City is one of the more accessible corners of the Bay Area.
