Single-family homes in the Valley Stream Union Free School District 13 sold for a median of $799,000 (typically $730,000–$850,000) across 179 recorded sales between Oct 7, 2025 and Oct 1, 2026, up 6.7% on the 12 months before. This home's $1,269,888 list price sits in the luxury single-family tier for the Valley Stream Union Free School District 13.

At about $11,688 a year, this home's property tax is in line with the roughly $12,000 typical for Valley Stream Union Free School District 13.

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.
