The Federal Housing Finance Agency, as part of its new servicing project, is once again reviewing minimum fees paid to servicers of Fannie Mae and Freddie Mac loans, according to industry advisors briefed on the matter. Among other things, the servicing project is reviewing how large-scale packages of GSE receivables are sold and transferred. This was not entirely unexpected, given the massive sales of mortgage servicing rights the past 18 months. But mortgage bankers thought changing the minimum servicing fee of 25 basis points was a dead issue.
