The median home value is $269,800, and median household income is $66,029. We use both figures to adjust labor and pricing for this page.
Cass County had 18 hail days and 27 days with damaging thunderstorm winds from 2020 through 2025, according to NOAA storm records. The largest hail reported was 2 inches across.
