Do I use the FHA Online Application if I want to apply for my branch office to be FHA approved?

No. The FHA Online Application is only for new applicants seeking FHA Approval.   The Mortgagee must register each branch office and pay branch office registration fees through the Lender Electronic Assessment Portal (LEAP). A 10-digit FHA Lender ID will be assigned to each registered branch office.
For an explanation of the branch registration process, please see the LEAP User Manual that can be accessed using the LEAP Information link in the Approvals & Renewals section at:
