Pretty much nothing in your screed is factual. The Minneapolis "building boom" reflects the general trend in most of the nation: expansion of the housing stock since about 2005 has been negligible, much less than 1 per hundred residents per year. This is about half the rate of real expanding cities like Houston.

I don't know what better signal you expect than the fact that median sale price of homes in Minneapolis proper has gone up 45% in only 5 years and the time to sell is now 11 days instead of 21 days in 2016, according to Redfin.
