Why is there a big difference between Cold Creek County and Jefferson County property values (near Denver)?
If you visit www.zillow.com and watch the heat "map" for the values of price per square meter, in Colorado, you'll see a strong north south line on the border between Cold Creek and Jefferson County, west of Denver. At Cold Creek County, per square meters is the average price of $ 150 to 200 between U.S. $, but on the other side of the line in Jefferson County, which is in the $ 300 – Cadena. $ 400 What?
Looking into it, "closer to Denver," the argument does not explain what we are seeing. The line is the extent of houses in Jefferson. I suspect a problem with your algorithm that calculates this.
