The median sale price in Portola Valley is $4.62M — up 9% from $4.25M in September 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 6% below the area's 5-year average of $4.90M. 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 $23,765 today, up 66% from $14,353 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 $15,611/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.
