Before move-in, confirm the signed lease, start date, first-rent amount, deposit treatment, and payment path. Then send one factual notice that tells the tenant what is due, the date it is due, and where to pay. Do not use a generic reminder to invent a charge, change a lease term, or substitute for any required local notice.

Confirm the record before sending the first message
The most useful move-in billing notice is built from verified records, not a memory of the deal. Check the signed lease, unit, tenant, start date, rent amount, deposit record, any agreed proration, and the payment status before you communicate a balance. If one of those records conflicts, resolve it first and leave a record of the correction.
Keep charges distinct in the message. Rent, a security deposit, a permitted fee, and a carried balance are different things. A tenant should be able to tell what each amount represents and which record supports it rather than receiving one unexplained total.
Open the lease and verify the parties, start date, rent, and payment due date.
Compare the expected first charge with the tenant ledger and any recorded deposit payment.
Confirm whether the lease states a proration method or a different first-period arrangement.
Send a factual message only after the records agree.
Write a message the tenant can act on
Lead with the decision the tenant needs to make: pay the listed amount through the tenant portal by the listed due date, or reply promptly if the record appears wrong. Include the unit or lease reference, itemized amounts, payment path, and a maintenance or access contact for issues that are not billing questions.
Avoid implying that an unpaid amount has already become a legal violation or that a reminder changes the lease. The purpose of the notice is to make the first payment easy to understand and document what was communicated.
Handle exceptions before they become a collection problem
If a tenant says the amount is wrong, pause the assumption that the next step is another reminder. Recheck the lease, ledger, receipt, proration method, and any move-in agreement. A dispute, duplicate charge, or habitability issue needs a documented human review, not an automated escalation.
If the tenant needs more time and you choose to consider it, use a documented payment-plan workflow instead of an informal text exchange. A plan is not created automatically; it is proposed, reviewed, and tracked as an owner decision.
