Portola Valley housing market trends, 2021–2026

October 2021 median
$4.33M
$14,850/mo at 3.1%
Peak (April 2022)
$8.75M
August 2026 median
$5.71M

The median sale price in Portola Valley is $5.71M — up 32% from $4.33M in October 2021. Over that stretch, the median peaked at $8.75M in April 2022 and bottomed at $3.50M in September 2022. That puts today's price about 16% above the area's 5-year average of $4.93M. Portola Valley averages only about 4 sales a month, so these swings partly reflect which specific homes happened to sell — treat the long-run direction as rough, not precise.

What buyers actually pay has moved more than the sticker price suggests: a typical monthly payment (20% down, principal & interest) is about $29,349 today, up 98% from $14,850 in October 2021. Most of that increase comes from mortgage rates (3.1% then vs. 6.7% now), not prices — at October 2021 rates, today's median would run about $19,601/mo.

Seasonally, the three months ending in October have been the busiest stretch for closings in Portola Valley over the past 5 years (about 14 sales in that window on average, vs. 9 for the stretch ending in March), while competition has run hottest in the stretch ending in May (49% 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.
