Data through July 2026
See how prices, monthly costs, and mortgage rates have moved in South San Francisco.
Includes principal, interest, estimated CA property tax (~1.25%), and estimated insurance (~$2,200/yr). HOA fees not included.
The median sale price in South San Francisco is $1.26M — up 3% from $1.22M in September 2021. Over that stretch, the median peaked at $1.43M in May 2022 and bottomed at $1.10M in December 2022. That's right in line with the area's 5-year average of $1.22M. 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 $6,474 today, up 57% from $4,129 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 $4,253/mo.
Seasonally, the three months ending in October have been the busiest stretch for closings in South San Francisco over the past 5 years (about 98 sales in that window on average, vs. 59 for the stretch ending in February), while competition has run hottest in the stretch ending in June (76% 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.
