Greenspan concerned about risky mortgages

Greenspan concerned about risky mortgages: "WASHINGTON -- Oct. 10, 2005 -- Federal Reserve Chairman Alan Greenspan is turning up the volume on his warnings about the potential perils of certain risky mortgages if the high-flying housing market loses significant altitude.

There are signs some companies are getting the message. A few have begun scaling back some types of those mortgages or making them less appealing by raising costs.

Greenspan mostly is worried about homeowners who took out an interest-only mortgage or option adjustable-rate mortgages to buy property they otherwise could not afford. Borrowers and lenders holding such loans could get clobbered if housing prices drop or interest rates rise."
