Start re-listing the unit the day you learn the tenant is leaving. Before you calculate anything, before you draft a letter, before you decide what you are keeping. In most states the size of your claim depends on what you did to re-rent, and the clock on that starts the moment you have notice.
The deposit question follows from the claim. It does not lead it.
The deposit is not a penalty
A security deposit secures performance. It is not a forfeiture, and a lease clause saying the deposit is forfeited on early termination generally does not make it one.
Deposit statutes list the purposes the money can be used for, and they read as compensation, not punishment. North Carolina’s list is unusually explicit about early departure:
N.C.G.S. § 42-51(a)
permitted uses include the tenant’s possible nonpayment of rent, damage to the premises, and damages as a result of the nonfulfillment of the rental period.
California’s is written more generally and gets to the same place:
Cal. Civ. Code § 1950.5(b)(1)
security may be used for the compensation of a landlord for a tenant’s default in the payment of rent.
Both are describing losses you actually suffer. Neither authorizes keeping a deposit because a lease ended in a way you did not like.
What you can usually claim
Four categories, and each has to be a real number rather than an estimate of your inconvenience.
Rent for the vacancy, from the day they left until the unit is re-rented or the lease term ends, whichever comes first. This is the big one and the one the re-rental duty cuts into.
Re-listing costs, if your state allows them: advertising, screening a replacement, and in some places a documented portion of a leasing fee. Check whether yours permits this before you assume it.
Unpaid rent and charges owed as of the departure date.
Damage and cleaning, exactly as at a normal move-out. Breaking a lease does not change the wear standard by a single line, and normal wear and tear versus damage still governs.
What you generally cannot claim is the rest of the lease term as a lump sum, a flat early-termination charge that has no relationship to your losses, or a doubling of anything because you are annoyed.
One structural point that saves arguments: a claim larger than the deposit is still a claim. If the vacancy and the damage come to more than you are holding, the deposit does not cap what the tenant owes, and the itemized statement should show the full total with the deposit applied against it. Conversely, a claim smaller than the deposit means a refund, on the same deadline as any other move-out.
The duty to re-rent changes the arithmetic
Most states require a landlord to make reasonable efforts to re-rent rather than sit on an empty unit and bill the departing tenant for the term. The doctrine has different names in different places, and the practical test is the same: did you behave the way you would have if the tenant had simply moved out at the end of a lease?
That means listing at a market rent rather than an aspirational one, showing the unit, and screening applicants on your normal criteria. A landlord who left the listing up at fifteen percent over market for two months has a much smaller claim than the calendar suggests.
Document all of it: the listing date, the price, the inquiries, the showings, and the approval. Those records are the difference between a defensible vacancy claim and an unsupportable one.
Then run the normal process
Once the loss is known, the deposit is applied against it like any other claim. Nothing about the early exit changes the mechanics.
- Do the move-out inspection and the comparison against the move-in report.
- Total the actual losses: vacancy through the re-rental date, permitted costs, unpaid rent, damage and cleaning.
- Apply the deposit, including any interest your state requires.
- Send the itemized statement within your state’s window, with documentation attached.
- Bill or refund the difference.
The deadline is the trap here. Landlords sometimes hold the statement until the unit re-rents so the vacancy number is final, and blow the return window doing it. If the timing does not work, several states allow a good-faith estimate with the real documentation to follow. How to write a security deposit deduction letter covers how to structure that, and security deposit limits by state covers where to find your own deadline.
A note on subletting and replacement tenants. If your tenant finds someone to take over and that person passes your normal screening, taking them usually ends the vacancy claim on the spot. Screening the replacement on the same written criteria you apply to everyone else is the part to get right, because relaxing them for a friend of the departing tenant is where fair housing exposure starts.
Two clauses worth checking before the next lease
The early termination clause. A clause setting a defined buyout, commonly a fixed number of months’ rent plus notice, is enforceable in more places than a bare forfeiture clause and is far easier to administer. Have a local attorney look at yours.
The statutory exceptions. Most states let a tenant leave early without liability in defined situations: military orders, domestic violence, and habitability failures are the common ones. Those are not breaches, and the deposit analysis above does not apply to them. Know which ones your state recognizes before you send a bill.
Keep the ledger, the vacancy dates, and the deposit on one record with deposit tracking, and run the final arithmetic through the deposit calculator so the statement leaves on time.
This is general information, not legal advice. Rules change and local ordinances vary. Confirm current requirements with your city, county, or an attorney before you act.
