Single-family homes in the Sachem Central School District sold for a median of $679,000 (typically $600,000–$750,000) across 523 recorded sales between Oct 7, 2025 and Oct 2, 2026, up 4.5% on the 12 months before. This home's $750,000 list price sits in the upper single-family tier for the Sachem Central School District.

ZIP 11779 has about 2 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 $11,726 a year, this home's property tax is in line with the roughly $11,000 typical for Sachem 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.
