How does a Mortgagee obtain FHA approval to originate FHA Mortgages nationwide?

An “Area Approved for Business” (AAFB) is the geographic area in which a Mortgagee’s home or branch office is permitted to originate or underwrite FHA Mortgages. The AAFB is subdivided into HUD Field Office jurisdictions.


All branch offices registered by a Mortgagee will initially be granted a nationwide AAFB. The branch may only exercise its authority to originate or underwrite FHA mortgages in those states where the Mortgagee fully complies with state origination and/or underwriting licensing and approval requirements.
