Condos in the Mount Sinai Union Free School District sold for a median of $720,000 (typically $570,000–$800,000) across 33 recorded sales between Oct 8, 2025 and Sep 24, 2026, up 10.8% on the 12 months before.

ZIP 11766 has about 3.3 months of condo inventory — seller's market. Demand is outpacing supply, so homes sell quickly with firm pricing and limited room to negotiate.

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.
