"Option" mortgages to explode, officials warn

Reuters reports:

The federal government and states are girding themselves for the next foreclosure crisis in the country's housing downturn: payment option adjustable rate mortgages that are beginning to reset.

"Payment option ARMs are about to explode," Iowa Attorney General Tom Miller said after a Thursday meeting with members of President Barack Obama's administration to discuss ways to combat mortgage scams.

"That's the next round of potential foreclosures in our country," he said.

Option-ARMs are now considered among the riskiest offered during the recent housing boom and have left many borrowers owing more than their homes are worth. These "underwater" mortgages have been a driving force behind rising defaults and mounting foreclosures.
