Here's a firm but polite draft you can copy and fill in:

**Subject:** Return of $1,400 Security Deposit - [Your Address / Unit #]

Dear [Landlord's Name],

I'm writing to follow up on the return of my security deposit.

I moved out of [your address] on [move-out date], which was about 7 weeks ago, and returned the keys at that time. I have not yet received my $1,400 deposit, nor an itemized list of any deductions. I've also tried to reach you by text a few times without hearing back.

Under our lease and state law, the deposit was due to be returned within a specific timeframe after move-out, which has now passed.

Please return the full $1,400 by [date - about 7 days from now]. If you are withholding any portion, please send me an itemized statement with documentation right away so I can review it.

I'd like to resolve this promptly and amicably. Please confirm by [same date] when I can expect the refund, or let me know if you need my current mailing address again. If I don't hear back, I'll need to consider my next steps to recover the deposit.

Thank you for your prompt attention to this.

Best,
Sam
