Smithtown Real Estate Market, September 2026

September 30, 2026 · Mia Kaiser, Licensed Real Estate Salesperson

Median price per square foot came down with it, to $385 from $424 in August and $411 a year earlier, so the drop was not only a matter of which houses sold. Forty three sales closed, the most in the past year and up from 27 in September 2025, while 32 new listings came on, the fewest in the past year.

The middle of the market did the work. Nineteen sales landed between $600,000 and $799,999, against seven a year earlier, and eight closed at $1,000,000 or more, up from four. Houses took a median of 21 days to sell, against 16 in August and 15 last September, and 31 of the 43 sales closed at or above asking, a share little changed from August and down from 85.19 percent a year ago.
