One of the defining features of the Midpeninsula housing market in 2026 has been the continued imbalance between buyer demand and available inventory.
Across Palo Alto, Los Altos, Menlo Park and even Atherton, buyer activity has strengthened since fall 2025, supported in part by continued wealth creation in Silicon Valley. At the same time, the number of homes coming to market has changed very little.
The result has been a familiar pattern: relatively limited inventory, quick sales for well-positioned homes, frequent multiple offers and continued upward pressure on prices. More than anything, scarcity remains the central force shaping the market.
Los Altos, Palo Alto, Menlo Park: Cash buyers make up a third of sales
Despite the noticeable increase in buyer demand, housing supply has remained remarkably constrained.
During the first eight months of 2026, the number of new single-family-home listings in Palo Alto declined 9% from the same period last year. Los Altos had essentially the same number of new listings, while Menlo Park recorded only a modest 2% increase.
The number of homes sold also changed little, declining slightly from a year ago across all three cities, suggesting that rising prices have been driven less by greater turnover than by increased competition among buyers for a limited number of available homes.
That dynamic is reflected in nearly every measure of market strength.
More than 70% of homes listed in all three cities sold, and homes that sold were on the market for a median of only eight to nine days. Nearly 80% of single-family homes sold at, or above, their asking prices.
The size of some overbids was equally striking. Roughly one-third of homes sold in Palo Alto and Los Altos closed more than $500,000 above asking. In Menlo Park, approximately 15% did so.
While Los Altos led the region in price appreciation during much of the past several years, Palo Alto and Menlo Park have been catching up in 2026.
The median price of a single-family home sold in Palo Alto reached approximately $4.1 million during the first eight months of the year, up 8% from the same period in 2025. That represents one of Palo Alto’s strongest sustained median-price levels and approaches the peak reached briefly during the pandemic-era market.

Menlo Park’s median price reached approximately $3.58 million, up 9% year over year. Los Altos reached approximately $4.9 million, about 3% higher than a year earlier.
Cash purchases provide another indication of the amount of capital competing for homes.
Nearly 40% of Palo Alto single-family-home purchases during the first eight months of the year were all cash, an unusually high percentage that was partly driven by a significant number of high-end transactions. The corresponding figures were approximately 33% in Los Altos and 37% in Menlo Park.
Palo Alto: Home values rise beyond the city’s priciest neighborhoods
The citywide numbers, however, mask significant differences among Palo Alto neighborhoods.
The most dramatic example is Old Palo Alto, where the year-to-date median sale price reached approximately $9.1 million, up 58% from a year ago.
That figure should be interpreted cautiously. Old Palo Alto has relatively few annual transactions, and this year’s sales mix included an unusually large number of expensive properties. Fifteen homes were listed above $10 million, compared with 10 during the same period last year.
Still, the fact that these high-priced homes consistently found buyers is meaningful. It reflects particularly strong demand for premium properties in Palo Alto’s most established neighborhood, even when asking prices already incorporate robust market expectations.
The shift is not limited to Palo Alto’s traditionally most-expensive neighborhoods.
On the other side of El Camino Real, Barron Park and Green Acres recorded substantial increases in median sale prices — approximately 21% in Barron Park and 31% in Green Acres. Their median prices, approximately $4.3 million and $4.6 million respectively, both exceeded Midtown and are now comparable with Green Gables at the north end of Palo Alto.
Barron Park offers a particularly good example of how a few transactions can reset buyer expectations.
A newly constructed home sold for more than $7.4 million, establishing a new benchmark for new construction on a roughly 10,000-square-foot lot. Demand subsequently remained strong for older homes on larger parcels offering redevelopment potential. One older home on an approximately 12,000-square-foot lot sold for nearly $5 million — more than $1.4 million above its asking price.
Crescent Park also remained strong, with its median sale price approaching $7 million, approximately 9% higher than a year ago.
The common thread across these neighborhoods is becoming increasingly clear: Buyers are placing the greatest premiums on either a finished product that is difficult to replicate or land that gives them the opportunity to build their own custom home.
Atherton: Median sale price tops $11M
Atherton has historically had a different kind of housing market from the rest of the Midpeninsula.
As one of the country’s most expensive residential communities, homes have traditionally taken longer to sell, negotiations have been more deliberate, and asking prices have often been treated as starting points rather than floors.
That pattern has changed noticeably this year.
New listings declined approximately 11% during the first eight months of 2026. At the same time, roughly 74% of homes brought to market during the period found buyers — ranging from properties priced below $5 million to estates approaching $40 million.
Prices moved sharply higher as well. The median sale price for an Atherton home reached approximately $11.3 million during the first eight months of the year, up 17% from the same period in 2025.
The median days on market for sold homes fell to only about 10 days. In other words, successful Atherton listings are now selling at a pace surprisingly similar to Palo Alto.
The overbidding statistics are equally unusual. Approximately one-third of Atherton homes sold for more than $500,000 above asking, while nearly 1 in 5 homes sold for more than $1 million above asking.
Scarcity is also reshaping neighborhood preferences.
With very little inventory available in the most sought-after area near the Menlo Circus Club, demand has increasingly shifted toward Lindenwood and areas south of Alameda de las Pulgas.
In Lindenwood, older homes on approximately 1-acre lots have crossed the $11 million threshold, 30% to 40% above levels seen only a year ago.
There is also growing interest in properties farther west and south, in part because high-end buyers appear increasingly willing to trade proximity for greater privacy and larger lots.
At the same time, rising land values are creating a new challenge for new-home construction in Atherton.
As land values continue to rise alongside today’s construction costs, the economics of building a high-quality new home are becoming increasingly demanding. As a result, bringing newly constructed homes to market in Atherton below $30 million may soon become much more difficult.
What could bring more homes to market?
The biggest question remains whether more inventory will come to market.
So far, higher prices have not been enough to motivate many homeowners to sell. Moving often means buying again in the same expensive market, facing significant tax consequences and giving up a low-mortgage rate or favorable property-tax basis. As a result, many sales continue to be driven by life events rather than price.
One factor that could bring more homes to market is a change in federal capital-gains policy. A temporary exemption of up to $1 million in real estate gains, particularly if extended to primary residences and investment properties, could encourage longtime owners with substantial appreciation to sell and temporarily bring more inventory to the market.
The other variable is the next wave of Silicon Valley wealth creation. New wealth from the AI-industry could encourage existing homeowners to trade up, potentially putting more homes on the market.
For now, the market’s core challenge remains the same: There are far fewer homes with the location, size, condition and privacy buyers truly want than there are buyers looking for them.
Until that changes, even highly qualified buyers will need patience.
