A firm deadline for payment should be set, and the tenant should be informed of the consequences of non-payment, which may include legal proceedings for eviction or recovery of the owed amount. The tone of the letter should be professional and assertive, yet courteous, to maintain a good landlord-tenant relationship. It is essential to adhere to local and state laws when drafting this letter, ensuring all legal requirements are met. Documentation supporting the claim, such as a rent ledger, should be attached, and a copy of the demand letter should be kept for records. This letter acts not only as a reminder but also as evidence of the landlord’s attempt to resolve the issue amicably before resorting to more severe measures.
