A national consumer advocacy group, whose own investigation of FHA credit overlays spurred a federal probe of nearly two dozen FHA lenders, said it is keeping an eye on Fannie Mae’s and Freddie Mac’s use of loan-level price adjusters as a potential discriminatory lending practice. The National Community Reinvestment Coalition said it’s still waiting to hear from the Department of Housing and Urban Development about the results of multiple investigations HUD launched in December 2010 after NCRC found that 22 lenders set borrower credit scores as high as 640 for FHA loans, even though the FHA guarantees loans with scores as low as 580.
