The short answer

Maryland’s guide treats the deposit as protection for actual loss, not an automatic penalty for breaking a lease. Its example deducts only the lost rent before the replacement tenant begins. Interest depends on the tenancy’s start date and applicable formula; use the state’s deposit-interest resource and ask for itemized actual damages.

Make the dispute specific

Send a dated written request identifying each disputed item, the correction requested and supporting evidence. Give a reliable forwarding address and preserve proof of delivery. A general statement that the apartment was fine is less useful than matching photos and receipts to the particular charge.

Ask whether the account has been assigned or sold and obtain the current owner’s details. Send any collector the relevant dispute and documentation through the appropriate process as well; a landlord complaint does not automatically correct the collector’s records.

Deposit rules do not answer every lease-debt question

Residential coverage, exemptions, local ordinances and the termination facts can change the deposit rule. A landlord returning the deposit does not necessarily waive a separate claim, and a deposit statement alone does not prove a balance is valid. Early termination, mitigation, subsidized housing and existing court judgments require their own review.

If court papers arrive, use the response procedure for the actual case. Deposit-return timing and lawsuit-answer timing are different deadlines.

Common questions

Can the landlord charge for ordinary wear?

The linked state rule explains permitted deductions and coverage. Distinguish normal aging from damage and compare the amount charged with evidence of the item’s prior condition and actual work.

Does missing a deposit deadline erase all rent debt?

Do not assume so. The consequence depends on the statute, the type of claim and the facts. A deposit remedy and a separate rent claim may be different issues.

What if a collector now has the balance?

Request the underlying account, service dates and deposit credits from the landlord and the collector. Preserve the dispute and respond separately to any lawsuit.
