ZIP 11581 has about 5.2 months of single family inventory — balanced market. Supply and demand are roughly even, so buyers and sellers share leverage with fair, predictable pricing.
At about $10,498 a year, this home's property tax runs roughly 13% below the $12,000 typical for Valley Stream Union Free School District 24. 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.
