Carmel Housing Stock
Half the homes in Carmel were built before 1997 (Census ACS median), so the typical house is about 29 years old.

With a median household income of $134,602 and a median home value of $455,500, local labor rates come out above the national middle in our model.
NOAA storm reports for Hamilton County show 13 hail days and 22 days with damaging thunderstorm winds over the six years from 2020 to 2025. The largest hail reported was 2.5 inches across. Hail flattens the thin aluminum fins on condenser coils and cuts airflow. After a big storm, take a look at the outdoor unit; homeowners insurance often covers the damage. Hamilton County also had 2 tornado days in that period.
