Subprime lenders have yet to learn from their mistakes. According to a consumer advocate group, abuses persist industry wide, despite the recent subprime mortgage meltdown. At a Senate subcommittee hearing on ending mortgage abuse this week, the Center for Responsible Lending (CRL) presented its findings on subprime loans included in 10 recent packages of mortgage backed securities. More than three quarters of the subprime loans CRL looked at turned out to be adjustable rate mortgages (ARMs). 90 percent of those were hybrid ARMs - otherwise known as “exploding” ARMs.
