Two-to-three-family homes in the Glen Cove City School District sold for a median of $800,000 (typically $780,000–$960,000) across 12 recorded sales between Oct 24, 2025 and Jul 17, 2026.

ZIP 11542 has about 3.3 months of multi-family inventory — seller's market. Demand is outpacing supply, so homes sell quickly with firm pricing and limited room to negotiate.

At about $12,753 a year, this home's property tax is in line with the roughly $12,000 typical for Glen Cove City 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.
