Map

Averages are weighted as total dollars over total square feet. We calculate averages based on closed sales in the MLS for the past 12 months, as of October 5, 2026. Averages are based on properties that are listed or sold for $350,000 and greater. Additional reports at all price points are available here. Price-per-square-foot figures are rounded to the nearest dollar, up or down. Where fewer than 5 closed sales exist in the window, we report the count rather than an average.
