Month-over-Month Changes

In September 2023, the Portola Valley real estate market showed some notable changes compared to August 2023:

  • Homes Sold: 4 homes were sold, marking a 33% increase from 3 sales the previous month.
  • Median Sale Price: Decreased by 39% from $7,450,000 in August 2023 to $4,530,000 in September 2023.

The month-over-month data indicates a market in flux. While the number of homes sold increased, the median sale price saw a significant drop. The decrease in DOM suggests that homes are selling faster, and sellers are receiving more than their asking price, indicating a strong seller’s market.

Year-over-Year Comparison

  • Homes Sold: Decreased by 43%, from 7 to 4.
  • Homes Listed: Decreased by 64%, from 14 to 5.

  • Median Days on Market: Increased from 7 to 21 days.
  • Percentage of List Price Received: Increased from 99% to 101%.
  • Months of Inventory: Decreased from 3.9 to 3.0.


Year-over-year, the market has seen a decrease in the number of homes sold and listed, but an increase in sale prices. The longer DOM and higher percentage of list price received suggest a market that is still favorable for sellers but requires more time for transactions to close.
