Start with the validation information you actually received
Under current CFPB Regulation F, the validation period for a covered debt collector starts when the required validation information is provided and ends 30 days after the consumer receives or is assumed to receive it. A written dispute submitted within that period can trigger the rule’s verification procedures for the disputed debt or portion.
Use Rental Ledger Audit to rebuild charges, payments, credits and adjustments. Then paste the copied reconciliation into the optional ledger-summary field so the collector can compare the claimed amount with the account entries you reconstructed.
Keep collection procedure and the original charge separate
A validation request does not replace review of the original rental account. Lease terms, move-out charges, deposit credits, utility lines, payments and state-law issues remain a separate underlying layer.
