Two-to-three-family homes in the Valley Stream Union Free School District 30 sold for a median of $940,000 (typically $800,000–$995,000) across 7 recorded sales between Jan 22, 2026 and Sep 28, 2026. Too small a sample to be statistically stable — that median rests on 7 recorded sales, so a single sale moves it substantially. Treat it as a starting point rather than a market reading.

ZIP 11580 has about 5.7 months of multi-family inventory — balanced market. Supply and demand are roughly even, so buyers and sellers share leverage with fair, predictable pricing.

At about $13,641 a year, this home's property tax runs roughly 24% above the $11,000 typical for Valley Stream Union Free School District 30. 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.
