Get Your Security Deposit Back with ChatGPT

ResearchedWhat this sticker meansBeginnerPersonal

Quick answer

Here's how I'd set this up in ChatGPT or Claude (not run by us yet). I'd upload my lease, my move-in and move-out photos, and the landlord's list of deductions, have the chat look up my state's deposit rules on official sites, and then send a polite demand letter myself.

Tools needed
ChatGPT, Claude
Typical cost
Free. ChatGPT Free and Claude Free both handle uploads and web search. Small claims filing fees, if you go that far, are set by your court.

Basis (estimate): Not measured yet. We haven't timed this.

What does this setup do?

You upload your lease, photos, and the landlord's deduction list, ChatGPT or Claude finds your state's official security deposit rules with web search, flags deductions worth questioning, and drafts a demand letter. You send it and decide on next steps.

Who is it for?

For renters who moved out and got back less than expected, or nothing at all, and want to push back in writing before thinking about small claims court.

How do you set it up?

Tools

  • ChatGPT Free or Claude Free. Both include web search and file uploads, and ChatGPT Free limits uploads.
  • Your lease, the landlord's itemized deduction list if you got one, and your move-in and move-out photos
  • Your state's official tenant rights page or handbook, which the chat can find with web search

Steps

  1. Gather your lease, any move-in checklist, your photos, and whatever the landlord sent about the deposit.
  2. Upload them with the prompt below. Black out account numbers first.
  3. Have the chat use web search to find your state's official tenant rights page. Deposit return deadlines and allowed deductions are set by state law, so go by the official page.
  4. Read the deduction review. Common things to question are charges for normal wear and tear and charges without proof, if your state's rules back you up.
  5. Ask for a short demand letter that cites the state rule from the official page, lists the deductions you dispute, and gives a date to respond.
  6. Send it yourself in a way you can prove, like certified mail or email. If it doesn't work, check your state's small claims court page or free legal aid.

Example output

Illustrative. Your results will differ.

  • State tenant handbook found and linked
  • 3 of 5 deductions flagged as worth questioning
  • Demand letter drafted with a 14-day response date. Nothing sent.

Where to paste this prompt

Copy-paste prompt

Adapt bracketed fields to your situation.

Help me get my security deposit back. Don't contact my landlord for me.

State and city: [state, city]
Move-out date and deposit amount: [date, amount]
What I got back and when: [amount, date, or nothing yet]
Attached: my lease, the landlord's deduction list (if any), and my move-in and move-out photos.

1. Use web search to find my state's official page on security deposits (attorney general, housing agency, or state tenant handbook). Link it. Tell me the return deadline and what landlords may deduct, quoting the official page.
2. Go through each deduction and say whether my lease, my photos, or the state rules give me grounds to question it. Mark anything you're unsure about.
3. Draft a polite demand letter under 200 words: dates, deposit amount, disputed deductions, the state rule with its link, and a response date.

Rules: Use only official government sources for the law. If you can't find one, say so. Don't invent laws, deadlines, or penalties. This isn't legal advice.

What usually goes wrong?

Where agents tend to stall on this job. More patterns in Where AI gets stuck.

  • Deposit rules, deadlines, and penalties are different in every state, and some cities add their own. The chat is only as good as the official page it finds.
  • Without move-in photos or a checklist, it's hard to show damage was already there.
  • This isn't legal advice. For larger amounts or a landlord who won't respond, talk to legal aid or a tenant lawyer.

Common questions

How do I get my security deposit back from my landlord?
Ask in writing, with your forwarding address, and point to your state's deposit rules. If the landlord keeps money you think you're owed, send a demand letter that lists the deductions you dispute.
How long does a landlord have to return a security deposit?
It depends on your state. Find the deadline on your state's official tenant rights page or handbook. USA.gov links to each state's tenant rights agency.
Can ChatGPT write a security deposit demand letter?
Yes. Give it your lease, photos, and the deduction list, and ask it to cite your state's official rules. Check the law it quotes against the official page before you send anything.
What can a landlord deduct from a security deposit?
Your state's law decides. Check your state's official tenant rights page for how it treats normal wear and tear versus damage, and whether the landlord has to itemize deductions.

Where should you go next on this site?

What tips make it smoother?

  • Take dated photos of every room on move-in and move-out day. They're your best evidence.
  • Give the landlord your forwarding address in writing when you move out.
  • USA.gov points to free legal aid for landlord and tenant disputes if you need a real lawyer.
