Old Westbury Real Estate Market Update: Inventory Remains Scarce as Prices Reach New Highs
The Old Westbury housing market continues to demonstrate a trend that has defined much of the luxury segment over the past several years: limited inventory paired with resilient demand.
While transaction volume remains modest, the latest OneKey MLS data through April 2026 suggests that buyers competing for quality homes are facing fewer options than ever, contributing to a sharp rise in home values across the village.
Inventory Falls to Multi-Year Lows
The most significant story in today’s market is supply. As of April 2026, there were just 16 single-family homes available for sale in Old Westbury, down 15.8% from last year and down 37.5% compared to the rolling 12-month average.
For perspective, only one new listing came to market during April.
In a community where many homeowners remain locked into historically low mortgage rates and have little incentive to move, the flow of new inventory continues to lag behind buyer demand. The result is a marketplace where exceptional properties often attract outsized attention.
Home Prices Continue to Climb
The scarcity of available homes has translated directly into higher values. The median sales price for a single-family home in Old Westbury reached $2,997,500 in April, representing a 51.4% increase year-over-year.
Looking beyond a single month, the longer-term trend is even more telling. The rolling 12-month median sales price now stands at $3,390,000, up 34.3% from a year ago.
Historical pricing data shows a clear trajectory: after a brief period of softness between 2018 and 2020, Old Westbury home values have experienced a sustained upward climb, reaching their highest levels on record. For homeowners who have not evaluated their property’s value recently, today’s pricing environment may look dramatically different than it did even two or three years ago.
Buyers Are Paying Close to Asking Price
Despite elevated home prices, buyers remain willing to compete for desirable properties. Over the past 12 months, sellers received an average of 91.9% of their original asking price, an improvement from 90.0% a year ago.
While headlines often focus on rising inventory in other parts of the country, Old Westbury remains largely insulated from those trends. Well-positioned homes continue to attract qualified buyers, particularly in the luxury segment where inventory remains constrained.
Homes Are Selling Faster Than Historical Norms
Although the small sample size in April caused average days on market to fluctuate, the broader trend remains favorable for sellers. Over the last 12 months, homes sold in an average of 120 days, compared to 128 days during the prior period.
Luxury properties naturally require longer marketing periods than the broader housing market, but the fact that homes are selling more quickly while prices continue to rise is another indication of underlying demand strength.
What This Means for Sellers
For homeowners considering a sale, current market conditions present a compelling opportunity:
- Inventory remains exceptionally low.
- Home values are at or near record highs.
- Buyers continue to compete for quality homes.
- Marketing times have improved despite higher price points.
In many cases, the greatest challenge facing sellers today is not finding a buyer—it’s determining where they’ll move next once their home sells.
Looking Ahead
The remainder of 2026 will likely hinge on whether additional inventory comes to market. If listing activity remains constrained, the fundamentals currently supporting price growth are likely to persist.
For now, Old Westbury remains one of Long Island’s most supply-constrained luxury markets, and that imbalance continues to favor homeowners.
