The only way to do that is once again allow exotic mortgages so people can get into mortgages out of their income range. Without this segment of the market, there is not enough leverage (buying power) for people to continue moving up into higher price ranges.
I agree, all this will do is slow the decent so we don’t have a catastrophic meltdown. Price are still going to head lower, and once they do stabilize, will have stagnant appreciation for at least a few years, if not longer…
