There are three claim submission categories: (a) Payment of the unpaid principal balance; (b) Reimbursement of eligible reasonable expenses, including interest, from the Date of Default to the earlier of the deadlines provided in § 1005.839(a) through (e). Allowable reasonable exceptions will be provided by Section 184 Program Guidance; and (c) Supplemental claim for eligible reasonable expenses incurred prior to the earlier of the deadlines provided in § 1005.839(a)(1) through (5), for expenses omitted from the Servicer's prior claim or for a calculation error made by either Servicer or HUD.
