Keep the deposit payment record, tenancy agreement, check-in and check-out reports, and dated photographs or videos showing the property's condition. Retain receipts, invoices or written quotes for cleaning, repairs or replacement items, along with rent payment records and messages about any alleged damage or deductions. If you are seeking repayment, keep evidence of the property's condition when you left and your requests for the deposit to be returned. The RTB may consider this evidence in a dispute, but the outcome depends on the facts of the individual tenancy.
