'Neutron Bomb' Mortgages Set to Blow in '07

"The option adjustable rate mortgage (ARM) might be the riskiest and most complicated home loan product ever created. With its temptingly low minimum payments, the option ARM brought a whole new group of buyers into the housing market, extending the boom longer than it could have otherwise lasted, especially in the hottest markets. Suddenly, almost anyone could afford a home -- or so they thought. The option ARM's low payments are only temporary. And the less a borrower chooses to pay now, the more is tacked onto the balance.

The bill is coming due. Many of the option ARMs taken out in 2004 and 2005 are resetting at much higher payment schedules -- often to the astonishment of people who thought the low installments were fixed for at least five years. And because home prices have leveled off, borrowers can't count on rising equity to bail them out. What's more, steep penalties prevent them from refinancing. The most diligent home buyers asked enough questions to know that option ARMs can be fraught with risk. But others, caught up in real estate mania, ignored or failed to appreciate the risk.

There was plenty more going on behind the scenes they didn't know about, either: that their broker was paid more to sell option ARMs than other mortgages; that their lender is allowed to claim the full monthly payment as revenue on its books even when borrowers choose to pay much less; that the loan's interest rates and up-front fees might not have been set by their bank but rather by a hedge fund; and that they'll soon be confronted with the choice of coughing up higher payments or coughing up their home. The option ARM is 'like the neutron bomb,' says George McCarthy, a housing economist at New York's Ford Foundation. 'It's going to kill all the people but leave the houses standing.'"
