A Missouri security deposit demand letter should be clear, factual, and specific. It should not be just "send my money." It should connect the move-out date, the 30-day deadline, the address record, any missing itemized list, and the amount you believe is due.
The point is not to threaten wildly. The point is to show, calmly and in writing, that you know the 30-day rule, the itemized-list requirement, the inspection right, and the consequence if money is wrongfully withheld.
What to include
- Your name and the rental address.
- The date the tenancy ended.
- The deposit amount.
- Your current mailing or forwarding address.
- Whether the landlord returned anything or sent an itemized list.
- Why any deductions are disputed.
- A clear request for payment or a corrected itemized list.
- Inspection notice, attendance notes, photos, or other condition proof.
- Carpet-cleaning lease language, receipts, and timing if that charge is disputed.
Missouri-specific points to mention
Missouri Revised Statutes section 535.300 generally requires the landlord to return the deposit or send a written itemized list of damages with any balance within 30 days after the tenancy ends.
If deductions are claimed, the letter should focus on whether they fit Missouri law: unpaid rent, restoration beyond ordinary wear and tear, certain actual damages from inadequate notice to terminate if the landlord mitigated, and carpet-cleaning costs only where properly supported.
Short sample
I moved out of [Rental Address] on [Date] and provided my mailing address as [Address]. More than 30 days have passed since the tenancy ended, and I have not received the full deposit, a proper written itemized list of damages, or the balance due. Please return the amount owed or send a corrected written itemization within [reasonable number] days.
Use the double-damages leverage carefully
If the landlord wrongfully withholds your Missouri deposit, you could win double damages in court. That is leverage. Keep the demand tied to proof: tenancy end, address record, 30-day deadline, itemization problem, inspection record, deduction issue, and amount actually owed.
