Single-family homes in the Middle Country Central School District sold for a median of $635,000 (typically $565,000–$710,000) across 528 recorded sales between Oct 6, 2025 and Oct 1, 2026, up 5.8% on the 12 months before. This home's $649,000 list price sits in the mid-market single-family tier for the Middle Country Central School District.
ZIP 11755 has about 3.3 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 $15,360 a year, this home's property tax runs roughly 28% above the $12,000 typical for Middle Country 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.
