Clinton & Edwards want to "freeze" mortgage rates

From Fortune:

"I have a plan - a moratorium on foreclosures for 90 days [and] freezing interest rates for five years, which I think we should do immediately," Clinton announced at what was the last Democratic debate before the Nevada Caucus on Jan. 19. ... John Edwards, has endorsed an even broader rate freeze - one lasting seven years

....such a freeze would be disastrous. Interest rates on new mortgages would skyrocket - perhaps past 8 percent, as the mutual funds, pension funds and other investors who typically provide capital to the mortgage market shift their money into other investments where the government isn't impairing returns. With higher mortgage rates eroding buying power, the downward pressure on home prices would only increase. Lower home prices would lead to even more defaults, as more folks who'd lost the equity in their homes choose to walk away from their mortgages.
