Remember how we got to where we are. If the Fed stops buying loans, rates will skyrocket and home values will plummet, and you will be stuck with a house you can’t pay for or sell. 16% of Californians aren’t making their payments, so there will be plenty more chances to buy.
Sounds like a sells gimmick; most people get attached to a house and lose their heads. As I said, remember how we got here.
