July to September 2026. Updated monthly from Redfin data.
Single-family homes in Atherton sold for a median of $11,995,218 from July to September 2026, up 65.2% from a year earlier. The median house spent 19 days on the market. Across all home types, 52.4% of 21 sales closed above list price.
With 2.3 months of supply, inventory is moderate. Well-priced homes still move quickly, while others sit longer.
Only 21 houses sold in this period, so a few sales can move the median a lot. Look at the two-year trend and price per square foot, not one number.
Each point covers three months of sales ending that month.

A guide to the city, its neighborhoods, and its homes.
Atherton is a residential town between Redwood City and Menlo Park. Zoning limits almost the entire town to single-family homes, and most lots are one acre or more.
The town has no downtown shopping district. Shops and restaurants are a short drive away in Menlo Park, Redwood City, and Palo Alto.
El Camino Real runs through the east side of town, and I-280 is a few minutes west. US-101 is a short drive east.
Atherton's Caltrain station is closed. The nearest stations are Menlo Park and Redwood City.
Most homes are large custom houses or new construction. Many buyers purchase older homes to remodel or rebuild.
Because so few homes sell each month, the monthly median price can swing widely. Look at the rolling numbers and the sale count together.
Public elementary schools serving Atherton depend on the address. Parts of town fall in the Las Lomitas, Menlo Park City, and Redwood City school districts. High school students attend the Sequoia Union High School District, and Menlo-Atherton High School sits in town. Several private schools, including Menlo School and Sacred Heart, have campuses in Atherton.
School boundaries change. Confirm the assigned schools for any address with the district before you buy.
Holbrook-Palmer Park has gardens, tennis courts, and event space. The town center rebuilt its civic buildings and library in recent years.
Stanford, Sand Hill Road, and downtown Menlo Park are about 5 to 10 minutes away.
