Single-family homes in the Syosset Central School District sold for a median of $1,315,000 (typically $1,050,000–$1,760,000) across 259 recorded sales between Oct 6, 2025 and Oct 2, 2026, up 7.7% on the 12 months before. This home's $988,800 list price sits in the entry single-family tier for the Syosset Central School District.
ZIP 11791 has about 3.6 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 $19,869 a year, this home's property tax is in line with the roughly $22,000 typical for Syosset Central School District. Nassau assessments run on a multi-year cycle, so the assessed value behind this bill can lag what the home actually sells for today. A sale does not automatically reset it, and 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.
