How does an early termination fee clause in a lease work for a landlord?

What the clause does

Without a clause, a tenant who leaves early still owes rent until the lease ends or you re-rent the unit, and many states also expect you to try to re-rent (the duty to mitigate). Working out the final amount takes time, messages and sometimes a court.

An early termination clause replaces that with a deal made in advance: the tenant gives the notice the lease asks for, pays the fee, and the lease ends on an agreed date. Both sides know the cost before they sign.

What to put in it

• Written notice: how many days ahead (30 to 60 is common), and how the notice is delivered.
• The fee: a fixed amount or a number of months of rent, due before or on the move-out date.
• The end date: the day the lease ends if the notice and fee are on time.
• Rent paid through that date, and the condition of the unit, handled as in the rest of the lease.
• What does not change: the security deposit is still handled under your state's deposit rules, and the tenant must still return keys and leave the unit clean.
• That the option is not available during any period when the tenant is in default, if your state allows that limit.

What makes the fee fair

Courts in many states treat a fee as an enforceable "liquidated damages" clause only if it is a reasonable guess of your real loss when it was written, and treat it as an unenforceable penalty if it is far higher. Your real costs are the vacant days, advertising, cleaning and turning the unit, and sometimes a leasing cost.

Example a made-up unit rents for $1,500. A typical turn takes 3 weeks of vacancy ($1,050 of lost rent), plus $300 in cleaning and paint touch-ups and $150 in advertising and showing time. That adds to $1,500, so a fee of one month of rent is easy to defend. A fee of four months, $6,000, would be hard to explain.

Some states regulate or cap this kind of fee. Some leases of regulated or subsidized housing have their own rules. Check your state's landlord-tenant law.

Rights that work no matter what the clause says

Some tenants can end a lease early by law, and a clause cannot take that right away. Federal law lets service members end a lease on certain orders (see the SCRA guide), and many states let a tenant who is a victim of domestic violence leave on notice (see the domestic violence guide). Others involve an unsafe or uninhabitable unit. Do not charge the fee in those cases.

If you have no clause and a tenant leaves, the options are in the broken lease guide.

How DoorKeeping handles it

Leases in DoorKeeping are e-signed, so the clause the tenant signed is stored with the lease and you can ask Claude or ChatGPT "what does the lease for 4A say about leaving early?" When a tenant gives notice, the ledger shows what has been paid, and you approve any charge before it posts. Rent stays in your own bank account, and anything involving money waits for your approval.

Questions

Is an early termination fee legal?

In most states a reasonable one is allowed if it is in the lease. A fee that is far higher than your real loss may be treated as a penalty. Check your state.

How much should an early termination fee be?

Many landlords use one to two months of rent. A good test is whether it roughly matches your real cost of re-renting the unit.

Does the fee replace the duty to re-rent?

If the tenant uses the clause and the lease ends on the agreed date, you have what the lease promises. Without a clause, many states expect you to try to re-rent.

Can a tenant who is a domestic violence victim be charged the fee?

Many states let such a tenant end the lease on notice without the fee. Check your state's rule.
