Single-family homes in the Mount Sinai Union Free School District sold for a median of $800,000 (typically $710,000–$985,000) across 104 recorded sales between Oct 14, 2025 and Sep 30, 2026, up 4.6% on the 12 months before. This home's $699,999 list price sits in the entry single-family tier for the Mount Sinai Union Free School District.
ZIP 11766 has about 2.3 months of single family inventory — seller's market. Demand is outpacing supply, so homes sell quickly with firm pricing and limited room to negotiate.
At about $14,163 a year, this home's property tax is in line with the roughly $15,000 typical for Mount Sinai Union Free 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.
