Not automatically. In 38 of 51 US jurisdictions the landlord has a duty to try to re-rent the property rather than simply charge you the remaining rent, and in most states they can only keep what they actually lost. Your deposit is not a last month's rent payment unless your lease and your state's law make it one.
This is the situation renters most often assume is hopeless, and it usually is not.
Is my deposit just last month's rent?
Usually not, and this is worth being clear about because a lot of landlords talk as though it is.
A security deposit is generally held against specific things: unpaid rent, damage beyond ordinary wear, sometimes cleaning. It is not a pre-payment of the final month unless the lease says so and your state permits it. Several states treat "last month's rent" and "security deposit" as legally different funds with different rules.
So a landlord who says "you left early, so I'm keeping the deposit" has skipped a step. They still have to show what they lost, and the deposit still has to be accounted for like any other deduction — itemized, in writing, within your state's deadline.
Does my landlord have to try to re-rent the property?
In most of the country, yes.
30 states impose a statutory duty to mitigate — the law explicitly requires the landlord to make reasonable efforts to re-rent rather than let the property sit empty and bill you for it. Texas puts it plainly: "A landlord has a duty to mitigate damages if a tenant abandons the leased premises in violation of the lease" (Tex. Prop. Code § 91.006).
8 more recognise the duty through case law rather than statute.
10 states impose little or no duty, which is a materially worse position to be in: Arkansas, Georgia, Massachusetts, Michigan, Minnesota, Mississippi, Missouri, Pennsylvania, Utah and Vermont.
In three states the question is genuinely unsettled — New Hampshire, South Dakota and West Virginia have no controlling residential decision either way. If you rented in one of those, nobody can tell you with confidence what the rule is, and anyone who states it flatly is overreaching.
Where the duty exists, the practical effect is significant. If the landlord re-rented the property three weeks after you left, the rent they collected from the new tenant generally reduces what they can claim from you. A landlord who did nothing to re-rent may not be able to charge you for the whole remaining term.
What can they actually charge me for?
Broadly, the loss they really suffered — not the loss the lease says they can name.
That usually means some combination of: rent for the period the property was genuinely empty, reasonable costs of re-letting, and any actual damage beyond ordinary wear. It generally does not mean the full remaining rent as an automatic figure.
Whether a particular charge is legitimate depends on your state's rules and on facts only your landlord holds — when they re-listed it, what they asked for it, when a new tenant moved in, what they spent. That asymmetry is the real problem here: the person who knows whether the charge is fair is the person charging you.
What about the early termination fee in my lease?
Six states — California, Delaware, Maryland, Oregon, Utah and Virginia — have statutes dealing specifically with early termination fees, and in some of them a valid fee replaces the landlord's other damages rather than sitting on top of them.
Elsewhere, a lease clause naming a flat fee may or may not be enforceable. Courts in many states will not enforce a clause that operates as a penalty rather than a genuine estimate of loss.
A fee clause is a reason to look more closely, not a reason to assume the matter is closed.
What if I left because something was wrong with the rental?
Then this may not be a lease break at all in the eyes of the law.
Most states have statutory routes out of a lease when a home is uninhabitable, and additional routes after domestic violence or military orders. Those routes change the analysis completely — the question stops being "how much do you owe for leaving" and becomes whether you were entitled to go.
That is a different situation and we cover it separately in I left because of problems with the rental.
What should I ask my landlord for?
Facts that only they have.
- When was the property re-listed, and at what rent?
- When did a new tenant move in?
- What was actually spent on re-letting, with invoices?
- How is the amount you kept calculated, line by line?
You are entitled to an itemized accounting of the deposit in most states regardless of why you left. Leaving early does not suspend that obligation, and a landlord who responds with a single number has not met it.
How do I know whether the amount they kept is defensible?
Honestly: from the outside, you often cannot.
Whether a deduction holds up turns on which of the three mitigation positions your state takes, whether the property was re-let and when, whether a fee clause is enforceable where you live, and whether the landlord met the itemization and deadline rules that apply to every deposit regardless of how the tenancy ended. Those interact.
This is what SecurityDeposit.co does. You answer questions about your tenancy, why you left, what you were charged and what you received. We work out which of your state's rules bear on your situation and produce a demand letter that raises them specifically — including the accounting your landlord owes you — ready to sign and send by certified mail.
You do not need a lawyer to send one, and the letter is often what turns a flat "you broke the lease" into an actual itemized answer.
Frequently asked questions
Can my landlord keep the whole deposit because I broke the lease? Generally they still have to show actual loss and itemize it. In most states they must also try to re-rent, which reduces what they can claim.
My landlord says the deposit covers my last month. Is that right? Usually only if the lease says so and your state allows it. A deposit and a last month's rent payment are legally different in many states.
They re-rented the place two weeks after I left but still charged me for three months. In the 38 jurisdictions recognising a duty to mitigate, rent received from a new tenant generally reduces what you owe. Ask when the new tenancy started.
Does giving notice before I left help? Often, yes. Written notice, and any offer to help re-rent, tend to matter in how a court views the situation. Keep a copy.
My lease has a two-month early termination fee. Do I just owe it? Not necessarily. Six states regulate these fees directly, and elsewhere clauses that act as penalties rather than genuine estimates of loss are frequently challenged.
I left early because of mould and the landlord ignored my repair requests. That may be a different legal situation entirely. See I left because of problems with the rental.
Last reviewed: 30 August 2026. Mitigation rules, early termination fee statutes and deposit rules vary by state and change. Check your state's current statute before relying on anything here.
Sources. The duty to mitigate is statutory in most states and established by case law in several others: Tex. Prop. Code § 91.006 ("A landlord has a duty to mitigate damages if a tenant abandons the leased premises in violation of the lease"); Cal. Civ. Code § 1951.2, which limits recovery to loss the tenant could not reasonably have avoided. In New Hampshire, South Dakota and West Virginia no controlling residential authority was located either way — treat those as unsettled.
