Condos in the Three Village Central School District sold for a median of $680,000 (typically $585,000–$750,000) across 35 recorded sales between Oct 22, 2025 and Sep 25, 2026, up 11.5% on the 12 months before.

ZIP 11790 has about 2 months of condo inventory — seller's market. Demand is outpacing supply, so homes sell quickly with firm pricing and limited room to negotiate.

At about $5,003 a year, this home's property tax is in line with the roughly $5,000 typical for Three Village Central School District. Suffolk bills combine town, school and special-district levies, so two homes at the same price in neighboring districts can carry materially different taxes. Exemptions such as STAR, Senior or Veteran move the number as well — a new owner's bill is often not the same as the seller's.
