The landlord's duty to mitigate when a tenant leaves early

DoorKeeping team

3 min read

In many states a landlord whose tenant breaks a lease must make reasonable efforts to re-rent the unit, instead of letting it sit empty and billing the tenant for every remaining month. If you do not try, a court can reduce what you recover. Advertise at a fair rent, keep proof of your effort, and charge the tenant for the real gap and costs, within what your lease and state allow.

What "mitigate" means

To mitigate damages is to take reasonable steps to limit your loss. For a landlord it means trying to find a new tenant for the unit. The tenant who left still owes what the lease says, but a landlord generally cannot collect rent for months the unit could have been rented if reasonable effort had been made.

The rule varies by state. Texas, for example, states it in Property Code 91.006: a landlord has a duty to mitigate damages if a tenant abandons the premises in violation of the lease, and a lease provision that waives that duty is void. In a few states the duty is weaker or comes from case law. Check yours.

What counts as reasonable effort

No statute lists every step, and courts look at the facts. A landlord who does what a sensible owner would to fill a vacancy is on solid ground. A typical record has the following.

  1. A prompt listing at a market rent, not an inflated one. See how to price a rental listing.
  2. Photos, a fair description and posting on the usual sites for your area.
  3. Answering inquiries and showing the unit within a normal time.
  4. Screening applicants with your usual written criteria. You are not required to accept a poor applicant.
  5. Keeping notes of each inquiry, each showing and why an applicant was not chosen.

You also do not have to give the unit priority over your other vacancies, and you do not have to lower the rent far below the market. You do have to act reasonably and promptly.

What you can still charge

Depending on your lease and state, the tenant who left may owe:

  • Rent until a new tenant starts or the lease ends, whichever is first.
  • Reasonable costs of re-renting, such as advertising and a leasing fee if your state and lease allow.
  • Unpaid charges and damage beyond normal wear, handled through the deposit.
  • An agreed early termination fee, if your lease has one and your state permits it.

Example a made-up tenant leaves with five months left at $1,500 a month. You list the unit within a week at the same rent and sign a new tenant who starts 6 weeks after the old tenant left. Your loss from rent is about 6 weeks, or $2,077 (6 weeks times $1,500 times 12 months divided by 52 weeks), plus documented advertising costs. You would not bill the full five months, which would be $7,500.

The deposit comes first, but it is not the cap

You can usually apply the deposit to what the tenant owes, following your state's itemized statement and deadline. If the loss exceeds the deposit, you may bill the tenant for the rest or sue in small claims. See tenant breaking lease options for the choices when a tenant announces they are leaving.

Common mistakes

  • Letting the unit sit while you finish repairs you could have done after listing.
  • Listing at a much higher rent than the old tenant paid and then claiming the vacancy as their fault.
  • Rejecting good applicants for a weak reason.
  • Keeping no notes, so you cannot show what you did.

How DoorKeeping handles it

DoorKeeping keeps the lease, the tenant's ledger and your emails to the tenant on the unit, so the amounts owed and the dates are in one place. You can ask Claude or ChatGPT, "What does unit 4A owe through the end of the lease, and when did it become vacant?" and check the answer against the ledger before you send anything.

DoorKeeping does not post listings or run showings, and it gives no legal advice. Keep your advertising and showing notes in the unit's documents.

Questions

Do I have to re-rent if my tenant breaks the lease?
In many states you must make reasonable efforts. Texas states the duty by statute and does not allow a lease to waive it. Check your state.
Can I charge the tenant for months the unit sits empty?
Only to the extent the vacancy was not avoidable with reasonable effort, and subject to your lease and state law.
What proof should I keep?
Dated listings, inquiries, showings and reasons for turning down any applicant, along with your costs.
