Single-family homes in the Hauppauge Union Free School District sold for a median of $850,000 (typically $750,000–$1,000,000) across 144 recorded sales between Oct 6, 2025 and Sep 30, 2026, up 8.3% on the 12 months before. This home's $749,990 list price sits in the entry single-family tier for the Hauppauge Union Free School District.
ZIP 11788 has about 2.7 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 $12,729 a year, this home's property tax is in line with the roughly $12,000 typical for Hauppauge 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.
