Access to mortgage credit is expanding, according to panelists at a real estate conference in Miami last week, albeit slowly, and some agree alternative scoring models are needed. Franklin Codel, executive vice president with Wells Fargo, said the company has expanded its credit parameters on FHA, Fannie Mae and Freddie Mac loans. “About 10 percent, maybe a little bit more, of the lending we’re doing today, a year and a half or two years ago would have been either an exception or outside our policy. We have expanded our credit box at Wells Fargo, and I think a lot of other lenders have done the same thing.”
