On March 2, 2016, Freddie Mac introduced its reorganized Seller/Servicer guide. The reorganization does not introduce any new requirements or change any existing requirements. Instead, it is designed to better reflect how and when sellers and servicers interact with Freddie Mac. Freddie Mac says that the reorganized guide utilizes a more intuitive workflow so users can navigate to the content they need more quickly and efficiently.
