Single-family homes in the Locust Valley Central School District sold for a median of $1,150,000 (typically $815,000–$2,250,000) across 132 recorded sales between Oct 31, 2025 and Oct 1, 2026, down 18.1% on the 12 months before.

At about $15,413 a year, this home's property tax is in line with the roughly $17,000 typical for Locust Valley Central School District.
