Single-family homes in the Sachem Central School District sold for a median of $680,000 (typically $605,000–$750,000) across 528 recorded sales between Nov 5, 2025 and Nov 2, 2026, up 4.6% on the 12 months before. This home's $449,000 list price sits in the entry single-family tier for the Sachem Central School District.

ZIP 11779 has about 2.1 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 $6,435 a year, this home's property tax runs roughly 42% below the $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.
