The Multifamily Selling and Servicing Guide has been simplified and rewritten. We restructured the Guide to maximize delegation and deliver an improved customer experience. We updated our pre-review categories and defined our new underwriting requirements to provide maximum clarity — making it easier for you to deliver loans.

DUS Navigate™ is your portal to our simplified and restructured Multifamily Selling and Servicing Guide and Multifamily Underwriting Standards (Form 4660).
