Condos in the Westbury Union Free School District sold for a median of $420,000 (typically $365,000–$470,000) across 24 recorded sales between Nov 25, 2025 and Sep 3, 2026, up 5% on the 12 months before.

ZIP 11590 has about 1.8 months of condo inventory — hot seller's market. Severe inventory shortage — homes sell fast and often draw multiple offers over asking, giving sellers maximum leverage.

At about $4,055 a year, this home's property tax runs roughly 19% below the $5,000 typical for Westbury Union Free 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.
