If you are a homeowner in your 50s or 60s and you're looking to downsize by selling your large suburban home now that your kids are all grown, do you even care if the home you bought years ago for $120,000 now has a "market value" of $800,000 only because of subprime mortgages and artificially low interest rates?
And how many people have the income to pay for that $800,000 home?
