September 30, 2026, updated · Danielle Sandella and Kim Fontanez, Licensed Real Estate Salespersons

Median price per square foot came down with it, to $385 from $424 in August and $411 a year earlier, and the typical sale took 21 days rather than 16 in August and 15 in September 2025.

Volume went the other way. Forty three houses closed, up from 40 in August and 27 a year earlier, the most in the past year, while 32 new listings came on, the fewest since last September. Thirty one of the 43 sales closed at or above asking, roughly the same share as August, and the median sale came in at 102.01 percent of list, down from 104.39 percent.

The spread explains much of the move in the median. Nineteen sales landed between $600,000 and $799,999, against seven in that range a year earlier, while eight closed at $1,000,000 and over, up from four. Only two sales came in under $400,000.
