Nightmare Mortgages

They promise the American Dream: A home of your own -- with ultra-low rates and payments anyone can afford. Now, the trap has sprung

For cash-strapped homeowners, it was a pitch they couldn't refuse: Refinance your mortgage at a bargain rate and cut your payments in half. New home buyers, stretching to afford something in a super-heated market, didn't even need to produce documentation, much less a downpayment.

Those who took the bait are in for a nasty surprise. While many Americans have started to worry about falling home prices, borrowers who jumped into so-called option ARM loans have another, more urgent problem: payments that are about to skyrocket.
