Worse than subprime? Other mortgages imploding slowly

By Kevin G. Hall | McClatchy Newspapers

WASHINGTON — Call it son of subprime. Experts warn that a new wave of mortgage foreclosures may be coming soon and could rival the default rates for subprime mortgages and slow efforts to find bottom in a prolonged national housing slump.

The mortgages in question are $230 billion of option adjustable-rate mortgages, creative lending products that flourished at the height of the housing boom. In an option ARM, a borrower can opt to pay less than his or her monthly balance due, and the difference is tacked onto the outstanding loan balance.
