I am writing to draw your attention to the matter of my security deposit, which has yet to be returned, despite my tenancy at [Rental Property Address] having come to an end on [Date of Lease Termination]. As per the terms of our lease agreement and the Philadelphia Tenant-Landlord regulations, I am legally entitled to the return of my security deposit within 30 days following the termination of the lease. It has now been [Number of Days] since the termination date, and I am yet to receive any communication or refund regarding the security deposit. I have thoroughly inspected the property upon moving out, ensuring that it was left in the same condition as when I first rented it, with only normal wear and tear. I followed all necessary procedures outlined in our lease agreement, such as professional cleaning, repairs, and removal of personal belongings. Therefore, there should be no reason for withholding any portion of my security deposit. I kindly request that you immediately return my security deposit in full, totaling [Amount of Security Deposit], to the address provided above. Failing to comply with this request will leave me with no choice but to pursue legal action to secure the return of my deposit, as allowed under the Philadelphia Tenant-Landlord regulations. Please be aware that this letter serves as a formal notice of failure to return the security deposit and a demand for its immediate return. I trust that, as a responsible landlord, you will take prompt action and address this matter accordingly. In accordance with the Philadelphia Tenant-Landlord regulations, I expect to receive a written explanation if any portion of the security deposit is being withheld along with the respective receipts or documentation to support those deductions. I kindly request a response to this letter within 10 days from its receipt. You may reach me at the provided contact information or via email at [Your Email Address]. Failure to respond within the specified timeframe will leave me with no alternative but to proceed with legal action to protect my rights as a tenant. Thank you for your immediate attention to this matter. I trust that our situation can be resolved amicably. Sincerely, [Your Name]
