The Santa Clara County median sale price for the same month was $1.65M. For 2026 to date the Los Altos median is $4.62M and the average is $4.70M, with a median price per square foot of $1,899 and an average of $1,966. The median is the middle sale when every closed sale is ranked by price; the average is the total of all sale prices divided by the number of sales. Both are calculated from closed transactions reported to MLSListings Inc. and update once a month.

Should I buy now or wait for prices to drop?
The five year table on this page shows the recorded trend rather than a forecast. Comparing January through September 2021 with the same months of 2026, the Los Altos median sale price has risen an average of 3.9% per year and the average sale price has risen 4.4% per year, with the year to date median lower than the year before in 2023. Waiting pays when the financing cost you avoid and the rent you pay in the meantime outweigh the change in price. A buyer brief models this for your own numbers before you commit to a strategy.

I built this entire data platform because I believe buyers and sellers deserve transparent, real time market intelligence, not guesswork. Every figure on every city page comes from the same MLS feed I use to advise my clients. The difference between a good deal and a great deal is knowing what the data says before you sit down at the table.
