What should a landlord do when a tenant says they will pay the late rent on Friday?

What to say back, in writing

A good reply is short, kind and exact. It confirms the date, the amount and the method, and it says that the rent and any late fee remain due until the money arrives. Here is a pattern you can adapt:

Example "Thanks for letting me know. I will expect $1,450 (rent $1,400 plus the $50 late fee) by bank transfer on Friday, the 12th. Until it arrives the balance remains due. If it does not arrive on the 12th, I will send the written notice our state requires." Every figure here is made up.

The written reply does three things. It shows you were reasonable, it fixes the date so nobody can later say they meant the 19th, and it keeps your rights from being waived by silence.

What a promise can cost you if you handle it loosely

• Waiver: in some states, a pattern of accepting late rent can make it harder to enforce the due date later. A written note that each late payment is an exception, not a new deal, helps.
• Notice clock: if you stop a notice period to wait for the promise, you may need to start over. Know your state's rule before you pause anything.
• Late fee: if you quietly waive it, say so in writing, and say it is a one-time waiver. Otherwise it may look like a new habit.
• Partial payment: if the tenant sends part on Friday, do not accept it blindly. See what your state says about taking partial rent after a notice.

Questions that tell you whether Friday is real

You are not their banker, but a few factual questions help you tell a timing problem from a bigger one. Ask them in a neutral tone and write down the answers:

1. What is the source of the payment on Friday (a paycheck, a benefit, a family member)?
2. Is the full amount coming, or part of it?
3. Is next month's rent also at risk?
4. Would a short written payment plan help?

If the answers suggest next month will be late too, move from a promise to a plan, or to your state's notice process. The longer a shortfall runs, the harder it is to catch up.

What to do on Friday

1. Check the bank feed in the morning and again at the end of the day.
2. If the full amount arrived, record it, thank the tenant, and send a receipt that shows the balance as zero.
3. If part arrived, record it against the oldest charge and send the new balance in writing. Then decide whether to accept a smaller plan.
4. If nothing arrived, send the notice you said you would send, the same day.

Following through the first time is what makes the next promise mean something. A tenant who sees that Friday really was the deadline is more likely to pay on time or tell you early next time.

How DoorKeeping handles it

You can tell Claude or ChatGPT "remind me to check the Smith payment on Friday and draft the notice if it is not there." Rent that arrives is matched to the tenant by memo and exact amount from your bank feed, the balance updates, and the notice is drafted for your one-tap approval rather than sent on its own.

Questions

Should I waive the late fee if the tenant promises to pay?

That is your choice. If you do, put it in writing as a one-time waiver so it does not become a habit or a waiver of the lease term.

Can I accept a verbal promise instead of a notice?

You can, but get it in writing and check that waiting does not reset or waive a notice your state requires.

What if they miss the promised date?

Do what you said you would do, usually the written notice. Following through is what keeps the next promise credible.

Does a promise change the due date in the lease?

No. Unless you sign something that changes the lease, rent is still due on the original date.
