Single-family homes in the Bayport-Blue Point Union Free School District sold for a median of $774,000 (typically $670,000–$995,000) across 83 recorded sales between Nov 7, 2025 and Oct 29, 2026, up 6% on the 12 months before.

ZIP 11705 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 $15,367 a year, this home's property tax is in line with the roughly $16,000 typical for Bayport-Blue Point 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.
