Will really depend on unemployment. With stagflation, crappy business earnings, rising rates (which the fed will def. raise), and record consumer debt... Something's going to break. We're just in the beginning phases of layoffs.

Will it plummet as much as it rose? Probably not, but a 15-20% decrease wouldn't be off the table depending on area. Housing is typically 15 year cycle and we're entering a new cycle.
