Nobody loses a deposit on the last day. They lose it over the preceding two years, in a series of small omissions that only become visible when somebody proposes a deduction.
These are the ten habits that make the difference. Most take minutes. None of them require you to know any law.
1. Photograph the property before you unpack
The single highest-value twenty minutes of any tenancy.
Once furniture is in, the floor beneath it and the wall behind it cannot be photographed — and those are exactly the surfaces a check-out inspection finds things on. Do it while the rooms are empty, even with the removal van waiting outside.
Wide shot from the doorway, then medium shots, then close-ups of anything marked. The method is in how to take photos that hold up.
2. Give every close-up a location
A tight photograph of a scratch could be any wall in the country. Take a medium shot first, showing the surface next to something fixed — a door frame, a socket, a radiator — so the mark can be found again.
This is the habit that separates photographs that settle disputes from photographs that produce two conflicting accounts.
3. Check the inventory, do not sign it
You are usually given around seven days to review it. Walk the property with the document open and go line by line.
Replace opinions with descriptions. "Good condition" stretches to fit whatever is convenient later; "2 small chips to worktop edge left of sink, photographed" does not. Email your comments so they are dated.
If there is no inventory, write your own and send it on day one. What is a check-in/check-out inventory report covers both cases.
4. Photograph meters with the serial number visible
Everyone photographs the number. Almost nobody photographs the serial number, and it is the part that ties the reading to a specific meter at a specific property.
Do it on the day you get the keys, and again on the day you hand them back, and send the readings to the supplier in writing the same day. See how to take meter readings.
5. Report every problem in writing
Never only by phone.
A dated email in March saying "there is damp appearing in the bedroom corner and the bathroom extractor does not work" completely changes a September argument about mould. It shows the landlord knew, and it moves the failure onto their side.
A phone call nobody logged is worth nothing to anyone reading a file later.
6. Keep the whole thread
Every reply, every message, every quote, every inspection report. Do not delete the annoying ones — those are usually the useful ones.
The same goes for the tenancy agreement, the prescribed information, the gas safety certificate and the deposit receipt.
7. Find out where your deposit is, in the first month
Your landlord has 30 days to protect it and to give you the prescribed information. Check that both happened, rather than assuming.
Search the schemes yourself — DPS, TDS and mydeposits in England and Wales — and save the result. If it is not there, you are in a much stronger position than you probably realise, and you have six years to act on it. See what to do if your deposit isn't protected.
8. Fix the small things yourself, properly
Filling and touching up a picture hook takes ten minutes. A landlord's decorator charging for a wall does not.
But do not start repainting whole rooms without asking — unauthorised decorating is itself a deduction, and mismatched paint looks worse than the mark you covered. If in doubt, ask in writing.
9. Photograph the empty property on the last day
After the final box is out, before you hand over the keys. Same positions as your move-in shots, so the two sets compare directly.
Then email the whole set to the landlord or agent that evening, with a line saying this is the condition the property was left in on that date. That email quietly settles a great many speculative deductions before they are ever made.
The full sequence is in the end of tenancy checklist. To tick it off room by room on the day, use the printable move-out checklist.
10. Store it where you will actually find it
This is the habit that undoes the other nine.
Camera rolls fail. By the time a tenancy ends, the move-in photographs are buried under thousands of unrelated images, in no order, impossible to hand over as a set. People arrive at disputes with eleven pictures because those are the ones they could find.
The test: could you, two years from now, produce a dated, organised set covering every room and send it to someone who has never seen the property, in one go?
The pattern underneath all ten
Every one of these is an act of recording, done by someone with no dispute in sight, for the benefit of someone reading a file later.
That is the uncomfortable truth about deposits. The decision is made by an adjudicator who never visits the property and never hears from you directly — they read what the two sides submit and decide which file supports its claims. Your ability to influence that is almost entirely determined by work you did months or years earlier.
There is no way to make it up afterwards. Which is why the boring advice is the right advice.
Where RentSeal fits
RentSeal exists for habit ten, and makes the other nine easier: one tenancy, photographs organised by room, notes attached, documents alongside, everything dated as it is added, and the whole thing exportable as a single pack when someone asks for it.
You can read how it works before signing up for anything, and creating a record is free.
RentSeal documents condition. It does not decide who is responsible for anything, it does not guarantee any deposit outcome, and this guide is general information rather than legal advice. For your own situation, speak to Citizens Advice, Shelter or a housing solicitor.
