It seems to me as if we are already watching the unraveling of the suburban lifestyle model. Of course none of us will know that until the decay is well advanced to the point of being clearly systemic.
What impacts that trend will have on real estate markets and the "bottom" are unknowable. But expect a trend toward multiple occupancy conversions and a spectrum of value shifts in the real estate inventory as units that are better located increase in value (eventually) and many units lose essentially all of their value. Like Detroit only scattered across the nation.
I also do not see America becoming more prosperous/capita for a generation or three. With a similar trend toward further stratification in income equality. How that will impact the RE market is any fool's guess. But again I expect increases and decreases in unit values as result.
