Fannie Mae last week announced two significant executive staffing changes. Leslie Peeler, senior vice president in charge of Fannie Mae’s National Servicing Organization, is leaving the GSE for a senior position with IBM’s mortgage group. It’s unclear what exactly Peeler will do for the mortgage division of IBM, which includes Seterus, a subservicer that works for Fannie Mae. IBM rarely discloses any information about its mortgage division.
