Generally that does not happen. During most RE downturns and the subsequent turnaround the prices came back slowy but steady. It happened in Texas in the '80's and Ca in the 90's. In both areas it took 8-10 years for prices to recover.
Maybe, but where those downturns as sharp as this one? I ask because I really do not remember the 80’s downturn and I seem to recall the 90’s one was mild.
