The Twin Cities, the seven metro counties, time to clear the real estate market.
It is a measure of the housing backlog, supply vs. demand.
The measure is, if no new housing were to come onto the market from today onward, how long would it take before the current supply clears the market.
While obviously an estimate, not an exact number for any locale, that is impossible to predict, here are the numbers, from the article, here ---
St. Paul 5.2 Months
Minneapolis 5.2 Months
Anoka County 7.5 Months
Carver County 6.9 Months
Dakota County 6.2 Months
Hennepin County 6.2 Months
Ramsey County 6.2 Months
Scott County 9 Months
Washington County 7.6 Months
So, Scott County looks most backed-up, then Washington County and "us," Anoka County.
