The old tenant has not moved out and the new tenant is arriving: what to do
If the old tenant has not left by the day the new tenant is due to move in, tell the new tenant today, offer a firm later date with a rent credit or another unit, and start the legal process against the old tenant if they will not leave. Do not change the locks, remove belongings or cut utilities. In states that follow the Uniform Act, such as Arizona and Kansas, a landlord who cannot hand over the unit owes the new tenant rent abatement and, on five days' written notice, the right to cancel and get money back.
What you owe the new tenant
When you sign a lease with a start date, you promise the new tenant the right to occupy the unit from that date. If someone else is still in it, you may be in breach of that promise even though the cause is the old tenant. The rules differ by state, so read your own statute and lease before you decide what to say.
Two states show the common pattern. Arizona's A.R.S. 33-1362 says that if the landlord fails to deliver physical possession, rent abates until possession is delivered, and the new tenant may end the agreement on at least five days' written notice and get back prepaid rent and the deposit. Or the new tenant may insist on the lease being honored and sue for possession and damages. If the failure is willful and not in good faith, the statute allows more: not more than two months' rent or twice the actual damages, whichever is greater. Kansas has a close match in K.S.A. 58-2560, with a smaller willful-failure cap: not more than one and one-half months' rent or one and one-half times the actual damages, whichever is greater. Both follow the Uniform Residential Landlord and Tenant Act. Other states treat it under contract law or their own statute.
This is a summary of two statutes, not legal advice. Check your state's landlord-tenant law and ask a local attorney if the new tenant threatens to sue.
What to do in the first 24 hours
- Find out whether the old tenant is leaving and when. A call or text asking "when will you be out?" is not a threat and gives you a date to plan around.
- Tell the new tenant as soon as you know. A short, honest message ("the previous tenant has asked for until Friday; here is what I can offer") keeps trust and keeps them from renting a truck for nothing.
- Check the lease end date and any notice the old tenant gave. If they gave notice to leave on a date and are staying past it, they are a holdover. See what to do with a holdover tenant.
- Offer the new tenant a choice in writing: a later start date, another vacant unit, or cancelling and getting everything back.
- If the old tenant will not leave, begin the eviction notice or filing your state requires right away. Every day you wait is a day you owe a credit.
Options to put in front of the new tenant
| Option | What it looks like | Watch for |
|---|---|---|
| Later start date | A new date in writing, rent starts on the day they get keys | Do not charge rent for days they could not enter |
| Rent credit | Credit for each day of delay, applied to the first full month | State whether it also covers extra costs such as a hotel |
| Another unit | A comparable vacant unit at the same rent and terms | A different unit needs an updated lease |
| Cancel and refund | Return prepaid rent, the deposit and any fees | Do it promptly, in writing |
Example a made-up $1,500 a month lease starts on the 1st of a 30-day month. The old tenant leaves on the 4th, so the new tenant gets keys three days late. Rent for those days is $1,500 divided by 30, which is $50 a day, so the credit is 3 times $50, or $150. If the new tenant paid $120 a night for a hotel for those three nights, an offer to cover that adds $360, and the total offer is $510.
Offering to cover real, receipted extra costs often costs less than a dispute. It is a business choice, not a rule; your lease or state law may already say what is owed.
What you must not do
- Do not lock out the old tenant, remove their belongings, shut off utilities or enter without proper notice to push them out. Those self-help steps are illegal in many states and can cost you more than the delay.
- Do not let the new tenant move in "around" the old tenant unless both agree in writing. Two households in one unit creates deposit, damage and liability problems.
- Do not promise a date you do not control. "Friday if they leave" is honest; "Friday" is a promise.
How to stop it happening again
- Set the new lease start date a few days after the old lease ends, not the same day, when you can.
- Confirm the move-out date in writing about two weeks ahead and book the walkthrough.
- Put a delay clause in the new lease that says what happens if possession is late (a daily credit and the right to cancel), so both sides know the rule.
- Keep a short waitlist or a second unit in mind. See the rental waitlist.
How DoorKeeping handles it
DoorKeeping keeps each lease with its start and end dates and the e-signed copy, so you can see which new lease starts the day an old one ends. Ask Claude or ChatGPT "which units have a new lease starting in the next 14 days and an old tenant still showing?" and it reads your leases. Any message to the new tenant is a draft you approve. DoorKeeping does not give legal advice. See the connect page.

Questions
- Can the new tenant sue if the old tenant has not left?
- Possibly. In states that follow the Uniform Act, such as Arizona and Kansas, a landlord who fails to deliver the unit owes rent abatement and may owe damages, more if the failure is willful. Check your state, and tell the new tenant early.
- Do I have to refund the new tenant?
- If the new tenant cancels because possession was not delivered, the statutes in Arizona and Kansas require the landlord to return the deposit, and Arizona adds prepaid rent. Other states vary, so read yours.
- Can I let the new tenant move in anyway?
- Not safely. Two households in one unit mixes up deposits, damage and liability. Move them in only after the old tenant is out, or under a written agreement all sides sign.
- Should I charge the new tenant rent for the days they cannot enter?
- No. Start rent on the day they get keys, or credit the delayed days against the first month.
