Mortgage Servicing & Escrow — impact tolerance ≤ 2 business days — ITOL

Impact tolerance: ≤ 2 business days — any month-end posting delay. Tax, insurance, and closing-date escrow disbursements are same-day-critical. The annual escrow statement carries Reg X's fixed 30-day regulatory clock (illustrative default — trace the derivation, then replace with your own harm analysis)

Definition: Mortgage payment posting, escrow management (tax and insurance), payoff processing, and customer servicing.

Why it is designated: RESPA (the Real Estate Settlement Procedures Act) and state servicing rules impose specific timing on escrow disbursements. A missed tax escrow payment causes property-tax delinquency. A missed insurance payment causes force-placed insurance issues. The escrow sub-ledger sits on the deposit core, so a core outage strikes both payment posting and disbursement capability at once.
