Check My DepositLast month's rent (LMR) and a security deposit are legally distinct in Illinois — even when both are collected upfront at signing. Under 765 ILCS 710/1, a security deposit covers damage and unpaid non-rent obligations. Last month's rent is prepaid rent, applied to your final month. Misapplying one as the other can create legal complications, and some states impose separate rules (including interest requirements) on last month's rent.
Some states (like Massachusetts) require landlords to pay interest on last month's rent. Keep a record of exactly what you paid and how it was labeled in your lease.
