Syosset's real estate values have seen consistent upward momentum, with the median estimated property value reaching $1,194,590, a 4.7% increase over the last 12 months. The short-term trend is even sharper, with a 2.6% increase in estimated value just over the last month.

The median list price for active properties currently stands at $1.84 million, reflecting the high-end nature of available inventory in the area. This is further supported by a median price per square foot of $641 for active listings, underscoring the borough's position as one of Nassau County's more expensive enclaves.

Inventory Trends: A Growing Selection for Buyers

In a notable shift for the North Shore, inventory levels in Syosset have increased significantly. There are currently 70 active properties on the market, a 7.7% increase from the previous month.

The 3.68 months of inventory represents a 26.9% increase compared to April 2025, providing buyers with the most options they have seen in over a year. While still a seller's market, this trend indicates that the "inventory crunch" is beginning to thaw, allowing for a slightly more measured pace, as evidenced by the 46-day median time on market for sold properties.

Strategic Advice
For Sellers

The market remains in your favor, particularly with the median sold price hitting a high of $1.5 million. However, with a 26.9% increase in inventory over last year, you are facing more competition than previous sellers. To maintain your leverage and secure a near-100% list-to-price ratio, professional staging and precise market-value pricing are more critical than ever.

For Buyers

The 7.6% monthly rise in inventory is excellent news for those who have been sidelined by the lack of choices. You now have 70 active listings to consider, ranging from mid-tier suburban homes to luxury estates. While the 98.8% sold-to-list ratio shows that sellers aren't giving much ground, the increased supply means you may have slightly more room to negotiate on terms or find a home that perfectly fits your criteria without a frantic bidding war.
