Lease Acceleration Clause
in Your Lease
What it actually means, what New York law says, what's specific to New York City - and exactly what to do. In plain English.
Quick Summary - What You Need to Know
- RPL § 227-e makes re-renting mandatory - your landlord must act in good faith once you vacate in breach.
- The replacement rent must be the lower of fair market value or your original lease rate.
- Any lease clause exempting the landlord from that duty is void as contrary to public policy.
- The burden of proof falls on the party seeking damages - normally the landlord chasing you.
- New York City adds nothing specific, while a Florida landlord can legally do nothing and bill you monthly.
Understanding the Lease Acceleration Clause
A lease acceleration clause says that the moment you break your lease, every remaining month of rent comes due at once. On a Manhattan one-bedroom with nine months left, that's a demand letter with a five-figure number on it.
New York doesn't let that paragraph run unchecked. RPL § 227-e forces your landlord to make reasonable, customary efforts to re-rent, and any lease language waiving that duty is void.
What renters assume
Renters read the acceleration paragraph, see the whole remaining balance, and assume it's legally owed the day they hand back the keys. Plenty just pay it.
What is actually true
In New York that clause can't outrun the statute. RPL § 227-e makes the duty to re-rent mandatory and non-waivable, so a landlord who never lists the unit has a damages problem, not you.
New York sits at the protective end of this chart. Florida landlords may legally stand by and bill you as rent comes due, and Georgia has no mitigation statute at all - while RPL § 227-e both demands the effort and voids any clause trying to sign it away.
Plain English Version
Your lease says the whole tab is due the second you walk out. New York treats it more like a concert ticket the venue has to try to resell - you cover what the seat actually lost, not the full face value.
Rent Acceleration Clause Example - What the Wording Looks Like in New York City, NY
The sample clause below is real lease language - a court quoted it word for word, and then ruled on it. What the judge decided is at the bottom of this block.
Find the equivalent paragraph in your own lease and read the two side by side. The wording will differ; the moving parts rarely do.
The clause the Montana Supreme Court had in front of it. It does not end where this extract ends - a further sentence on late fees and interest follows in the lease and is not printed below:
If any monthly installment under this agreement is not paid when due and remains unpaid after a date specified by a notice to Tenant, the entire principal rent amount owed for the full lease term shall at once become due and payable at the option of the Landlord and judgment may be had for all said amounts due. The foregoing provision shall not relieve the Landlord of its obligation to mitigate damages. In the event the rental premises is re-rented to another for full value prior to expiration of the lease term, Landlord shall file Notice of Partial Satisfaction of any judgment entered to the extent of the third party rental agreement.

“shall not relieve the Landlord”
In New York a lease cannot say the opposite of this. RPL § 227-e voids any provision exempting a landlord from the duty to re-rent, as contrary to public policy, so the drafter who wrote this concession in gave away nothing and a drafter who left it out would be no better off. What the statute does not do is bless the first half of the paragraph. It regulates what the landlord must do after you go; it says nothing about turning the balance of the term into a debt on the day a payment is missed.
“is re-rented to another”
The lease treats re-renting as something that might happen. New York treats it as something the landlord has to attempt, and the trigger is your departure: the duty attaches once the tenant vacates in violation of the lease, and the standard is reasonable and customary action taken in good faith. Note what is missing on both sides. Our New York record fixes no deadline for any of it, and the paragraph you signed fixes none either.
“for full value”
Full value is the lease's measure. New York's is narrower and the difference is money. Section 227-e requires re-renting at fair market value or the rate agreed in your lease, whichever is lower. In a falling market those are two different numbers and the statute picks the smaller one, so a landlord holding the unit empty rather than dropping below your old rent is not meeting the standard the statute sets. A clause that credits you only when the unit fetches its former price is measuring by the wrong yardstick.
“to the extent of the third party rental agreement”
The credit is capped by whatever the replacement tenant actually agreed to pay, which makes the replacement lease the document that decides most of the argument - and in New York you are not the one who has to produce it. Under § 227-e the burden of proof is on the party seeking to recover the damages, so a landlord suing for the balance has to show what the unit did and did not earn. Compare California, where Civ. Code § 1951.2 puts the avoidable-loss proof on the tenant instead.
The Montana Supreme Court struck this paragraph down, and its conclusion is one sentence: “Thus, we conclude that the accelerated rent provision is unconscionable and therefore unenforceable.” The tenants had moved out of their apartment on October 13, 2006, and Crestview answered with a Statement of Deductions from the Security Deposit charging rent through the end of the lease in June - $6,505.75 billed against a $2,170 deposit. Two reasons carried the court. Acceleration undermines the landlord's duty to mitigate and reduces the incentive to re-rent promptly, because a landlord already holding a judgment for the whole term has little reason to fill the unit. And Crestview drafted the lease while these tenants had no meaningful choice and no opportunity to negotiate any of it. The case was reversed and remanded, and two justices wrote separately - their objection being that the majority had gone as far as treating acceleration clauses as unenforceable in themselves. So read the holding narrowly, as the majority wrote it: this provision, in this residential lease, unconscionable and unenforceable. It is a Montana decision and it binds no other state's courts. What travels is the reasoning, and the reasoning is about mitigation - which is exactly the question the statute in your own city's decode answers.
One court, one lease, one state. That answer is not automatically yours, and your lease may be worded to land differently. Use this to know what to look for and what to ask - your state's tenant hotline or a local tenant attorney can answer it for your document.
New York Law on Lease Acceleration Clause
- Section 227-e requires the landlord, in good faith, to take reasonable and customary action to re-rent at fair market value or the lease rate, whichever is lower.
- Any lease provision exempting the landlord from this duty is void as contrary to public policy.
- The burden of proof is on the party seeking to recover damages.
- The statute sets no deadline; the duty attaches once the tenant vacates in violation of the lease.
N.Y. Real Prop. Law § 227-e - statutes change; verify the current text for your situation.
The duty kicks in when you vacate in violation of the lease, with no notice ritual required first. RPL § 227-e makes your landlord act in good faith to take reasonable and customary steps to re-rent, at the lower of fair market value or your lease rate.
Two details do the heavy lifting. Any provision exempting the landlord from that duty is void, and the burden of proof sits on whoever is seeking the damages. California runs the opposite way: under Civ. Code § 1951.2 the tenant has to prove the rental loss could have been avoided.
New York Tenant Protections
RPL § 227-e requires your landlord, in good faith, to take reasonable and customary action to re-rent your unit once you vacate in violation of the lease. Any lease provision exempting the landlord from that duty is void as contrary to public policy, so signing it changes nothing. The burden of proof rests on the party seeking to recover damages, which means your landlord has to document the effort rather than simply bill you.
What's Specific to New York City
Figures are the state rule, or the stronger city ordinance where one exists. Verify the current law for your own situation before relying on it.
New York City adds nothing specific on acceleration. RPL § 227-e already applies citywide, and the HPD and rent-stabilization rules renters hear about cover different ground - renewals, registration, harassment - not what you owe after breaking a lease.
The market does the work no ordinance does here. Vacancy across Manhattan, Brooklyn, and Queens stays tight, and a unit in Astoria or Bed-Stuy often resurfaces on StreetEasy within days. Screenshot that new listing the moment it appears, because it's the evidence that shrinks whatever shortfall your landlord can prove.
It should. RPL § 227-e makes that duty mandatory, and a lease that stays silent doesn't erase it.
Fair leases show the math. New York credits the re-rental at the lower of fair market value or your lease rate.
Red flag. That full-balance number ignores RPL § 227-e, which cuts the claim by whatever good faith re-renting should have brought in.
Push back before signing. Any provision exempting your landlord from RPL § 227-e is void as contrary to public policy.

Red Flags to Watch Out For
-
Full remaining rent due immediately
The clause bills every unexpired month the day you leave. RPL § 227-e still cuts that claim by what reasonable, customary re-rental efforts should have recovered.
-
Waiver of the mitigation duty
Language saying the landlord has no obligation to re-rent. In New York that provision is void as contrary to public policy, whatever you signed.
-
Acceleration stacked on re-letting fees
The lease takes all remaining rent and a separate re-letting charge. Ask in writing which amounts are being credited against the re-rental before you pay.
-
Unit relisted above your rent
Your old apartment reappears priced higher than you paid. RPL § 227-e sets the target at the lower of fair market value or your lease rate.
-
No proof of re-rental effort
A move-out bill with no listing dates, showings, or new rent. The burden sits on the party seeking damages, so demand that record in writing.
Your Rights as a New York City Tenant
-
A landlord who must try
RPL § 227-e obligates good faith, reasonable and customary action to re-rent once you vacate in violation of the lease. Sitting on the unit isn't an option.
-
Waivers that don't count
Any lease provision exempting your landlord from that duty is void as contrary to public policy, so signing the paragraph doesn't make it enforceable.
-
The lower of two rents
The re-rental target is fair market value or your lease rate, whichever is lower - a landlord can't hold out for a premium on your dime.
-
The burden isn't yours
New York puts proof on the party seeking to recover damages. California flips that: Civ. Code § 1951.2 makes the tenant prove the loss was avoidable.
What To Do - Step by Step
Find the acceleration paragraph
Search your lease for 'accelerate', 'all remaining rent', or 'balance of the term'. That wording is the number your landlord will open with.
Put your move-out in writing
Email and mail a dated notice. The duty under RPL § 227-e attaches once you vacate in violation of the lease, so make that date impossible to argue about.
Return keys with a paper trail
Photograph every room and hand back keys on a date you can prove. The same record settles both the rent fight and the deposit fight.
Track the relisting
Check StreetEasy, Zillow, and the management company's own site weekly. A listing that goes up within days undercuts any accelerated demand.
Demand the mitigation record
Ask in writing for listing dates, showings, and the new rent. The burden is on the party seeking damages, not on you.
