Tight Inventory and NYC Migration Drive Bidding Wars in Westchester Real Estate Market

The residential real estate market across Westchester County remained intensely competitive in Q3 2025, as strong buyer demand pushed prices higher despite limited inventory. To spotlight the most competitive local markets, The Zach & Heather Harrison Team at Compass — the No. 1 residential sales team in Westchester — released a new
Bidding War Intensity Chart, ranking towns by the sharpest drops in Days on Market (DOM), a leading indicator of bidding war activity.

According to the team’s exclusive analysis, year-to-date single-family home sales rose 4.7 percent, with total sales volume climbing 10.4% to nearly $5 billion ($4.347 billion to $4.799 billion). The county-wide median sale price for single-family homes jumped 6.3 percent to $999,000, while the average price increased 5.4 percent to $1.34 million.

Condos and co-ops also saw strong appreciation, with median condo prices up 6 percent and co-op prices rising 9.8 percent year-over-year. Overall, the market continues to tighten — and the new intensity chart confirms where buyer competition is most aggressive.

“It’s an incredibly tight market,” said Zach Harrison, co-leader of The Zach & Heather Harrison Team. “The level of demand has led to a surge in bidding wars across nearly every price point. Buyers are coming prepared, and listings priced right are often receiving multiple offers within days.”

Heather Harrison added, “We’re seeing a noticeable uptick in buyers coming from New York City, especially with the uncertainty around the upcoming mayoral election. There’s been a sharp increase in families looking to leave
the city and settle in the suburbs before year-end. Westchester’s schools, space and stability are drawing strong interest.”

While sales volume and prices have risen, condo sales declined slightly by 3.3 percent, and rental activity dipped by 1 percent, suggesting that buyers are aggressively shifting toward ownership amid changing market conditions.

The Bidding War Intensity Chart visualizes the towns where buyer demand is strongest—those with the steepest drop in DOM are most likely experiencing multiple-offer scenarios and aggressive competition. Active listings across Westchester County have dropped dramatically since before the pandemic, underscoring just how tight inventory
has become.

According to MLS data, the number of single-family homes on the market in September totaled roughly 1,700 countywide—down from more than 5,100 in September 2019, representing a stunning 67 percent decline in active
listings countywide. Every community has felt the squeeze: on average, towns recorded a 72 percent drop in active listings over that six-year period, illustrating the severe supply constraints driving today’s competitive market conditions.

As the year closes out, The Zach & Heather Harrison Team anticipates continued upward pressure on prices, fueled by limited inventory and a growing exodus of city dwellers looking north. “As we head into the end of the year, we
expect prices to keep climbing,” said Zach Harrison. “There’s simply not enough inventory to meet the demand, and the flow of buyers moving up from the city has only intensified. Every well-priced home is getting multiple offers—it’s
an incredibly competitive environment.
