Single-family homes in the Copiague Union Free School District sold for a median of $621,000 (typically $560,000–$705,000) across 187 recorded sales between Oct 7, 2025 and Oct 2, 2026, up 6.2% on the 12 months before. This home's $599,999 list price sits in the mid-market single-family tier for the Copiague Union Free School District.
ZIP 11726 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 $8,135 a year, this home's property tax runs roughly 26% below the $11,000 typical for Copiague 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.
