If a lender has multiple addresses, which should go in the Administrative Address field?

The Administrative Address is the street address to which HUD administrative notices from the HOC Quality Assurance and Processing and Underwriting Divisions, Office of Lender Activities and Program Compliance, Mortgagee Review Board (MRB), Office of General Counsel, and Office of Inspector General (OIG) are sent, including requests and/or demands for indemnification.
