November 27, 2007 -- It is estimated that 7.2 million families in the United States have subprime mortgages. Of these 14.4%, or 1.04 million, are currently in default. This according to a new statistics by the Center for Responsible Lending. In the last ten years, the subprime loan industry has emerged as a major, and controversial, player in the housing market. Under a subprime loan, customers with low credit ratings are offered mortgages in return for high interest rates. Proponents have advocated subprime financing as a way for low-income residents to own their first home. But new figures suggest the subprime industry is having the opposite effect.
