Not enough new housing is built, and the few new builds get snapped up by investment groups and rental companies. Any old house hitting the market is in a tug of war between the companies , house flippers, and the odd millennials looking to buy a home. You also have huge swathes of housing being wiped out by freak weather events every year now; fires, flooding, derecho's and tornado's ect.

I don't think it's a bubble.
