Co-ops in the Smithtown Central School District sold for a median of $260,000 (typically $240,000–$305,000) across 6 recorded sales between Oct 8, 2025 and Sep 29, 2026, down 8.8% on the 12 months before. Too small a sample to be statistically stable — that median rests on 6 recorded sales, so a single sale moves it substantially. Treat it as a starting point rather than a market reading.
ZIP 11787 has about 3.6 months of co-op inventory — seller's market. Demand is outpacing supply, so homes sell quickly with firm pricing and limited room to negotiate.
