Fannie Mae and Freddie Mac should revise their seller/servicer guidelines to allow use of credit scores from more than one provider in order to “foster competition,” according to a bipartisan quartet of House Financial Services Committee members. In a letter sent to Federal Housing Finance Agency Director Mel Watt, Reps. Ed Royce, R-CA; Spencer Bachus, R-AL; James Himes, D-CT; and Carolyn Maloney, D-NY, said that the GSEs should not be restricted to relying on credit scores provided solely by the Fair Isaac Corp.
