Fannie Mae’s new regional headquarters under construction in the Dallas metro area is the target of criticism from Sen. Chuck Grassley, R-IA.He questions the Federal Housing Finance Agency’s management of the project in which the GSE is combining three locations into the one leased building. This comes on the heels of the FHFA Office of the Inspector General issuing a management alert late last year raising concerns about the cost of the consolidation and relocation of Fannie’s high-rise offices in Plano, TX. Grassley wants answers as to how the agency plans to address the issues identified in the IG management alert.
