Some data and predictions for the BNA housing market. There are others also and they say about the same.
I think what you’re seeing in BNA is what AUS was right before its housing market decline.
AUS for example has abt 3500 houses on the market with dom increasing, coupled with about 12k Airbnbs and vrbos, mostly people with rooms to rent long-term (think, bring in a roommate to help cover expenses).
BNA seems to be following AUS similar trends in housing, auto and other markets.
