Single-family homes in the Smithtown Central School District sold for a median of $845,000 (typically $735,000–$995,000) across 440 recorded sales between Oct 6, 2025 and Oct 2, 2026, up 5% on the 12 months before. This home's $1,649,999 list price sits in the luxury single-family tier for the Smithtown Central School District.
ZIP 11767 has about 1.9 months of single family inventory — hot seller's market. Severe inventory shortage — homes sell fast and often draw multiple offers over asking, giving sellers maximum leverage.
At about $25,404 a year, this home's property tax runs roughly 69% above the $15,000 typical for Smithtown 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.
