Can I use the security deposit for unpaid rent?

In most states, a security deposit can be applied to rent a tenant still owes, usually once the tenancy ends. If a renter moves out behind on rent, you can typically use the deposit to cover the shortfall before returning any balance.

The deposit is not limited to rent. It generally also covers damage beyond normal wear and, in some cases, cleaning or unpaid utilities named in the lease. What it covers, and in what order, can vary, so read your lease and your state law guide before you decide.

Applying a deposit to rent mid-lease, while the tenant still lives there, is where landlords get into trouble. In many places you cannot draw down a deposit for rent until the tenancy is over, even if the tenant is late.

Watch the last month's rent trap too. A security deposit and prepaid last month's rent are different funds with different rules. You can only treat a deposit as the final month's rent if the lease says so, or you both agree in writing. Guessing here invites a dispute you will probably lose.

Whatever you keep, put it in writing. Most states require an itemized statement that lists the unpaid rent and any other deductions, sent to the tenant within a set window after move-out.

• List each charge, such as rent owed by month, plus any damage or cleaning.
• Attach proof, such as the rent ledger, receipts, and dated photos.
• Return any remaining balance to the tenant on time.
• Keep a full copy for your own records in case of a claim.

Miss the deadline or skip the itemization, and some states force you to return the whole deposit, even rent you were genuinely owed. The paperwork is what makes the deduction stick.
