Lease Acceleration Clause
in Your Lease
What it actually means, what Oregon law says, what's specific to Portland - and exactly what to do. In plain English.
Quick Summary - What You Need to Know
- ORS 90.410(3) requires a landlord to make reasonable efforts to re-rent an abandoned dwelling unit for a fair rental.
- Re-renting for a term that starts before your lease ends terminates the old agreement on the new tenancy date, cutting off further rent.
- A landlord who skips reasonable efforts, or accepts the abandonment as a surrender, has the agreement deemed terminated as of the date they knew or should have known.
- Month-to-month exposure after abandonment is deemed a month; week-to-week is deemed a week.
- Our Oregon record sets no dollar cap and no re-renting deadline, so reasonableness is judged case by case.
Understanding the Lease Acceleration Clause
A lease acceleration clause says that the day you leave early, every remaining month of rent comes due all at once. On a Portland two-bedroom with eight months left, that paragraph turns a move into a five-figure demand letter.
Oregon is friendlier here than most states. ORS 90.410(3) puts an affirmative duty on the landlord: once you abandon the unit, they have to make reasonable efforts to rent it again at a fair rental, so an empty apartment is their problem too.
What renters assume
Renters read the acceleration paragraph, assume the entire remaining balance is legally owed the day they hand back the keys, and pay it rather than argue.
What is actually true
In Oregon that clause runs into a statute. Under ORS 90.410(3) the landlord shall make reasonable efforts to re-rent at a fair rental, and rent stops accruing against you once a new tenancy begins.
Notice that the chart has labels, not numbers - no state on it, Oregon included, reduces this to a single figure. Oregon sits with Washington and Arizona in the group where the duty to re-rent kicks in on abandonment, well ahead of Florida and Pennsylvania, where a landlord can let the unit sit empty and keep billing.
Because our Oregon record sets no cap and no deadline, a Portland renter can't point at a number the way a rule with a dollar limit would allow. What you get instead is a duty you can force your landlord to prove they met.
Plain English Version
Think of it like walking out on a gym contract. Oregon makes the club genuinely try to resell your spot at a fair price, and the moment somebody takes it, your bill stops - but nobody wrote down how fast they have to find that person.
Rent Acceleration Clause Example - What the Wording Looks Like in Portland, OR
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.
Reproduced from the opinion. The lease paragraph does not stop here - a sentence about late fees and interest on accelerated amounts follows it and is not set out 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.

Quoted from the published opinion in Summers v. Crestview Apartments, 2010 MT 164, 357 Mont. 123, 236 P.3d 586 (No. DA 09-0489). Judicial opinions are not subject to copyright; the lease language is reproduced in limited part for commentary under 17 U.S.C. § 107.
“remains unpaid after a date specified”
Acceleration does not fire the moment a payment is late. This wording makes the whole balance depend on a second event - a notice going out and a date on it passing - so the date on that letter is the hinge the rest of the paragraph swings on. Our Oregon record covers what a landlord must do once a tenant abandons the unit and does not reach the notice step this sentence is built on, which leaves the paragraph you signed as the document that answers it.
“due and payable at the option”
The whole remaining term becomes collectable only if the landlord chooses it, and in Oregon that choice runs into the statute. Under ORS 90.410(3) a landlord who accepts an abandonment as a surrender, or who does not make reasonable efforts to re-rent at a fair rental, is treated as having terminated the agreement as of the date they knew or should have known the unit was empty. A landlord cannot both take the unit back and keep the option open indefinitely.
“not relieve the Landlord of its obligation”
This half of the paragraph is the half Oregon renters should read first, because in Oregon the duty does not depend on the landlord agreeing to it in the lease. Where a tenant abandons, state law requires reasonable efforts to rent the unit for a fair rental, and the record sets no dollar cap and no deadline, so reasonableness is judged on the facts. Not every state works that way: Florida’s § 83.595 expressly lets a landlord stand by and hold the tenant liable for rent as it comes due, and Pennsylvania’s Supreme Court held in Stonehedge Square that a landlord there need not re-rent at all.
“entered to the extent of the third party”
Here the lease offers a credit: money the replacement tenant pays comes off the judgment. Oregon’s statute is stronger than a credit. Where the landlord re-rents on a term that begins before your lease would have ended, the rental agreement terminates as of the new tenancy’s start date, so rent stops accruing against you from that day rather than being netted off at the end. The difference matters most on a long remaining term, where a credit still leaves the landlord holding a judgment for the full figure.
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.
Oregon Law on Lease Acceleration Clause
- ORS 90.410(3) states that if the tenant abandons the dwelling unit, the landlord shall make reasonable efforts to rent it for a fair rental.
- If the landlord re-rents for a term beginning before the original agreement expires, the rental agreement terminates as of the new tenancy date, cutting off further accrual against the departed tenant.
- If the landlord fails to use reasonable efforts to re-rent at a fair rental, or accepts the abandonment as a surrender, the agreement is deemed terminated by the landlord as of the date the landlord knows or should know of the abandonment.
- For month-to-month or week-to-week tenancies the remaining term is deemed a month or a week respectively, so exposure after abandonment is short.
- The statute fixes no dollar cap and no deadline for re-renting, so reasonableness is judged case by case and an acceleration clause cannot collect rent the landlord should have avoided losing.
- Portland City Code 30.01.085 was read directly and contains no rent-acceleration or mitigation provision.
ORS 90.410(3) - statutes change; verify the current text for your situation.
The core rule is short. ORS 90.410(3) says that if the tenant abandons the dwelling unit, the landlord shall make reasonable efforts to rent it for a fair rental, which is an affirmative duty rather than something you have to argue from general contract principles.
Two things follow. If the landlord re-rents for a term beginning before your original agreement would have expired, the agreement terminates as of the date of the new tenancy, so nothing further accrues against you. And if the landlord fails to use those reasonable efforts at a fair rental, or accepts the abandonment as a surrender, the agreement is deemed terminated by the landlord as of the date they knew or should have known of the abandonment.
Our Oregon record sets no dollar cap and no deadline for re-renting, which leaves the paragraph you signed as the document that answers how the number gets built. Because the primary source was unreachable, so read the current ORS 90.410 text yourself before relying on it.
Oregon Tenant Protections
For a month-to-month tenancy the remaining term after abandonment is deemed a month, and for week-to-week it is deemed a week, so exposure on those tenancies is short by statute. If a new tenant moves in before your term would have ended, the old agreement terminates on that date and further rent stops running against you.
And an acceleration clause collects nothing by itself - a landlord who wants that money has to sue and satisfy a judge that reasonable efforts at a fair rental were actually made.
What's Specific to Portland
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.
Our record finds no Portland ordinance on rent acceleration or the duty to mitigate, so ORS 90.410 controls whether you're leaving a Hawthorne fourplex or a new build in the Pearl. The city's strongest renter protection, Portland City Code 30.01.085, was read directly and contains nothing on rent acceleration, early tenant exit, or mitigation.
That ordinance is still worth knowing, because renters mix it up with this. It governs landlord-initiated terminations and large rent increases - 90-day notice and relocation assistance from $2,900 for a studio or SRO up to $4,500 for three bedrooms or larger - which is money flowing to you when the landlord ends the tenancy, not a rule about what you owe after leaving early.
Good sign, and it matches ORS 90.410(3), which already requires reasonable efforts at a fair rental after abandonment.
That tracks the statute. Re-renting for a term starting before your lease ends terminates the old agreement on the new tenancy date.
Red flag. Acceleration on day one ignores the re-rental credit Oregon builds in once a fair rental is found.
Question it in writing. ORS 90.410(3) states the landlord shall make reasonable efforts, so check the current statute text before accepting a lease that says otherwise.

Red Flags to Watch Out For
-
All remaining rent due at once
The clause bills every unexpired month the day you return keys. Our Oregon record sets no cap on that demand, but the re-rental duty still shrinks what can be proved.
-
No mention of re-renting at all
A lease silent on replacement tenants leaves the whole question to ORS 90.410(3). Ask in writing what efforts were made and at what asking rent.
-
A fair rental that isn't fair
The unit gets relisted well above your rent and predictably sits. The statute asks for a fair rental, so save the listing price and the dates.
-
Acceleration stacked on a re-letting fee
You're billed all remaining rent and a separate lease-break charge. Ask which amount is credited against the other before paying anything.
-
A lump sum with no math
A number in a letter is not a judgment. Demand the re-rental date, the new rent, and an itemization before you treat the balance as owed.
Your Rights as a Portland Tenant
-
A statutory duty, not an argument
ORS 90.410(3) requires reasonable efforts to rent the abandoned unit for a fair rental. You are not left arguing general contract principles.
-
Rent stops when someone moves in
If the landlord re-rents for a term beginning before your lease ends, the agreement terminates as of the new tenancy date.
-
Doing nothing ends the lease
Failing to use reasonable efforts at a fair rental, or accepting the abandonment as a surrender, deems the agreement terminated as of the date the landlord knew or should have known.
-
Short terms, short exposure
For month-to-month the remaining term is deemed a month, and week-to-week a week, after abandonment.
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 start from.
Give dated written notice
Email it and mail it, with the exact date you're out. A provable move-out date is what starts the clock on when the landlord knew of the abandonment.
Return keys and document the unit
Photograph every room and hand keys back formally. A rent-ready unit removes the easiest excuse for leaving it empty.
Track the relisting weekly
Check Zillow, Apartments.com, and the building's own site. Save the date and asking price, because ORS 90.410(3) asks for a fair rental.
Demand an itemized statement
Ask in writing for the re-rental date, the new rent, and receipts. Rent stops accruing once a new tenancy begins before your term would have ended.
