Sample Letter Demanding Security Deposit for a Rental Property Dispute
To: Landlord Name
Address
Dear Landlord,
I hope you are doing well. I am writing regarding the security deposit for the property at 123 Maple Street (Lease No. 9876). After moving out on September 15, I was not refunded the full deposit amount of $1,200, as agreed upon in my lease contract dated June 1. I received only $800, leaving a shortfall of $400.
Below is the breakdown of deductions you claimed:
- Cleaning fee: $200
- Unpaid utilities: $100
- Repair for damages: $200
According to our lease, cleaning fees are only refundable if a third‑party cleaning service is used, and repairs were not documented with a signed work order. Therefore, the $400 remains unjustified.
Kindly process the remaining balance by October 15, 2026, in the same form of payment I used for the deposit. Please let me know if you need any further documentation or a meeting to discuss this matter.
Thank you for your prompt attention to this issue. I look forward to resolving this amicably.
Sincerely,
Tenant Name
