The data isn’t relevant since it’s not for the area defined. We are talking about a specific geographic area. Kansas City proper.

Due to the white flight of the 70’s housing prices declined or only grew fractionally.

When my grandparents died, each of their homes only sold under 20k in the late 90’s early 20’s.

Comparing the price of home across the Midwest has nothing to do with the price in East Kansas City or SE where I went to school
