Somewhere between the third apartment tour and the moment you get the keys, you'll sign more paper than you have in years — and most of it will vanish into an email thread or a drawer. Two years later, when a landlord deducts $900 from your deposit for "wall damage" that was there before you ever saw the place, that vanished paper is the whole case.
Renting has three document moments: the application, the lease, and move-in day. Each one produces something you'll want later. Here's what to keep from each.
The application: have your packet ready before you tour
Good apartments in tight markets go to whoever can apply today. Landlords and property managers typically ask for some mix of:
- Pay stubs — usually your two or three most recent
- Photo ID — driver's license or passport
- References — previous landlords' names and numbers, sometimes a letter
- Bank statements or an employment letter — for freelancers and new hires especially
- A completed application with your rental history
Gather these as PDFs before you start touring, and you can apply from the sidewalk outside the showing while everyone else is promising to "send it over tonight." One caution, though: an application packet is an identity thief's starter kit — income, ID, address history, sometimes your Social Security number. Don't leave it sitting in old email threads with strangers' addresses on them. It's worth two minutes to learn how to share documents securely from your iPhone — expiring links and a quick cleanup afterward — instead of emailing your life to every listing that might already be rented.
And keep the packet after you're approved. You'll need nearly the same documents for the next apartment, and pulling last year's version and swapping in fresh pay stubs beats rebuilding it from scratch.
The lease: read it, then keep it like it matters
The lease is the one document in this story that controls everything else, and it's routinely signed in ninety seconds and never seen again.
Before you sign, actually read the parts people skip: the deposit terms (how much, what it covers, when it comes back), notice requirements (how many days before moving out, and in what form), renewal and rent-increase language, and who pays for what repairs. If anything was promised verbally — "we'll replace the fridge before you move in" — ask for it in writing, even just an email. A promise that isn't written down expires the moment the leasing agent changes jobs.
After you sign, make sure you have:
- The fully signed lease — every page, with both signatures, not the unsigned draft from the email thread
- All addenda and riders — pet agreements, parking, roommate additions
- The deposit receipt — proof of the amount and the date you paid it
Then put copies somewhere you can find them in year three, not just week one. The signed lease answers questions that come up constantly — what's the late fee, when does the term end, how much notice do I owe — and the person who can pull it up in ten seconds wins every one of those conversations.
Move-in day: an hour of photos is worth a month's rent
This is the step people skip, and it's the one that decides deposit disputes. Before you unpack a single box, walk the empty apartment with your phone:
- Photograph every room — each wall, the floor, the ceiling, inside closets.
- Get close-ups of every existing flaw: scratched floors, chipped tile, stained carpet, that mysterious dent in the oven door. Wide shot for context, close-up for detail.
- Open every appliance and photograph the inside. Run the taps; shoot anything that drips.
- Don't stage anything. Blurry and honest beats artistic.
Your phone stamps every photo with the date and time automatically — that's your timestamp, and it's exactly what makes the record credible later. Then do the part that doubles its value: if the landlord gave you a move-in checklist, fill it out, sign it, and keep a copy. If they didn't, email them your photos with a short note — "documenting condition at move-in, June 1." Now the record exists on both sides, dated, and nobody can claim it was made up afterward.
If you're coordinating this alongside the chaos of the move itself, the moving-house paper trail — address changes, utility setups, mover contracts — is its own list worth having.
During the tenancy: everything in writing, always
The habit that protects you for the whole lease is simple: no important conversation stays verbal. Texted the landlord about the leak? Fine — screenshots count. Called them? Follow up with an email: "Confirming our call today — you'll send a plumber Thursday for the bathroom leak reported June 12."
Keep as you go:
| Document | Why it matters later |
|---|---|
| Rent receipts or payment records | Proof you paid, if ledgers disagree |
| Repair requests and responses | Shows problems were reported, not caused by you |
| Any notice from the landlord | Rent increases and entry notices have legal timing rules |
| Renewal offers and amendments | The terms you're actually living under |
| Your own notices to the landlord | Proof you gave notice on time, in the required form |
None of this is much paper. All of it is the difference between "I definitely told them about that" and a dated record that says so.
The dispute two years later
Here's how deposit disputes actually go. You move out. Weeks later, a letter arrives: deductions for damage, cleaning, repainting. If you have nothing, it's your memory against their invoice — and their invoice is written down.
If you kept the trail, the reply takes twenty minutes: move-in photos showing the scratch predates you, the lease clause on the deposit, the repair request proving the leak was reported in year one, your notice email with its date. Documented tenants get their deposits back, not because they argue better, but because there's nothing left to argue about.
The failure point is never taking the photos — it's finding them in year three, somewhere in a camera roll that's grown by ten thousand pictures since. That's the problem Paperlock is built for: it reads what you save, so the lease, the deposit receipt, and the move-in photos file themselves, and "what does my lease say about the deposit?" or "find my move-in photos" gets you the answer with the documents attached — behind Face ID, years later, in seconds. It's how the whole app works, and it's coming soon to iPhone.
However you store it, keep it — a lease is firmly on the list of documents worth keeping long after they seem done. The rental paper trail costs you about an hour across the whole tenancy. The deposit it protects is usually a month's rent or more. Few hours pay better.
