Single-family homes in the Sachem Central School District sold for a median of $680,000 (typically $600,000–$750,000) across 501 recorded sales between Oct 17, 2025 and Oct 2, 2026, up 4.6% on the 12 months before. This home's $599,990 list price sits in the entry single-family tier for the Sachem Central School District.
ZIP 11738 has about 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 $11,191 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.
