What to check in the building, not the room
At a viewing, attention goes where the decision seems to be: the room, its size, whether the bed fits, the light. That’s the part being sold and the part with your name on it.
It’s also the part you’ll spend the least conscious time in. What determines whether a share works is almost entirely outside that door — the kitchen, the bathroom queue, the hallway, the walls, and the building’s own condition. Those are harder to look at because nobody presents them to you, and they’re where the information is.
The kitchen, properly
The kitchen is the room where a shared household actually happens, and it will tell you more in three minutes than the bedroom tells you in twenty.
Storage per person. Count cupboards and count residents. A kitchen with four cupboards and five people has a daily friction problem that nobody mentions in the listing. Look for whether existing storage is divided or communal — either is fine, but the arrangement tells you how the household operates.
Fridge space. Same arithmetic, and more acute. A single small fridge in a house of five is a recurring irritation.
Whether two people can be in there at once. Physically. Stand in it and imagine somebody else cooking.
The state of it, adjusted for the hour. A kitchen mid-use on a weekday evening looks lived in and that’s normal. What you’re reading is the baseline underneath: whether surfaces are worn but clean, or whether things have been accumulating. Grease on the extractor and the top of cupboards is a slow signal and hard to fake either way.
Ventilation. An extractor that works, or a window that opens. A kitchen with neither produces a house that smells of last night.
The bathroom and the queue
Count the bathrooms against the residents, then ask about the morning. One bathroom and four people on the same schedule is a structurally different flat from one bathroom and four people on staggered ones — a difference rather than a flag, but a consequential one.
Run the hot tap. Ask first; nobody minds. You want to know how long it takes and whether the pressure is real. This is the single most useful physical check available at a viewing and virtually nobody does it.
Look at the ceiling and the grout. Black mould in corners and along seals indicates ventilation that doesn’t cope. It recurs, it’s a health matter, and it is the landlord’s to fix — which makes it also a test of whether anything gets fixed.
Check whether there’s a window or a working extractor. Same reason.
Ask where the boiler is and how old it is. You won’t be able to assess the answer, but you’ll learn whether anybody knows, and a household that has no idea has never needed to find out, which is either good news or means nobody asks.
The walls, the doors and the noise
This is the thing people most regret not checking.
Stand in the room and be quiet for thirty seconds. Actually stop talking. You’ll hear the road, the neighbours, the pipes, or nothing.
Knock on the wall between the room and the next one. You are looking for whether it’s solid or hollow stud partition, which changes everything about living next to somebody.
Note where the room sits. Above the kitchen, next to the bathroom, beside the front door, facing the street: each of those is a specific nightly experience. The room next to the bathroom in a house of five is a different room from the one at the end of the corridor.
Does the door lock, and does the window open and close properly. Both are basic and both are sometimes not true.
The building and the entrance
The communal parts, in a flat. The stairwell, the entrance, the bins. Communal areas are maintained by whoever’s responsible for the building rather than by the household, so their state tells you about the management rather than about your future housemates — which makes them a fairly honest signal.
How the front door works. Whether it closes properly, whether the entry system functions, whether the letterboxes look intact.
Where the bins go and who takes them. A trivial-sounding question that surfaces both the local collection arrangement and how the household divides ordinary work. What you do with the answer is a matter for the household to agree, not for this site.
Damp, generally. Look at the bottom of walls, behind furniture where you can, and at the window reveals. Trust your nose over your eyes; damp has a smell that decorating doesn’t cover.
Heating. What kind, whether every room has it, and whether the radiator in the room you’d take is plumbed in and working. Ask when it was last serviced.
Flag check
FLAG CHECK — the parts nobody shows you
· Black mould along bathroom seals or in
ceiling corners
→ recurring ventilation problem
and a health matter. Whose job
it is varies by jurisdiction.
· Damp smell, or fresh paint on one patch of
one wall at floor level
→ WALK AWAY unless you get a
convincing explanation.
· No window and no working extractor in the
bathroom or kitchen
→ flag. It doesn't improve.
· Hollow stud wall between your room and the
next
→ NOT A FLAG. A difference, and
the main thing worth knowing
before you commit.
· Kitchen mid-use and messy on a weekday
evening
→ NOT A FLAG. That's a kitchen.
· One bathroom for four people
→ NOT A FLAG. Depends entirely
on whose hours clash.
· Nobody in the house knows where the stopcock
or the meter is
→ mild flag. Suggests nothing has
ever needed fixing, or that
nothing ever gets fixed.
The question that beats all of this
“What’s the most annoying thing about living here?”
Ask a housemate rather than the lister, casually, while you’re in the kitchen. Most people answer honestly because it’s a small confession rather than a large one, and the answer is nearly always something real that no inspection would have found: the neighbour, the water pressure at eight, the window that doesn’t shut, the bin collection.
The ones who say “nothing, it’s great” are either being loyal or haven’t lived there long, and both are worth knowing. It works well as part of meeting the household rather than as an interview question.
What the building can’t tell you
It can’t tell you about time. A viewing is one moment: the pressure in the shower at two on a Saturday is not the pressure at eight on a Monday, and a warm flat in July says nothing about February. Almost every serious complaint about shared housing is a complaint about a condition that only exists at certain hours or in certain months.
It also can’t tell you whether things get fixed. The state of the building tells you about the past; the only guide to the future is whether anyone can name a repair that was reported and what happened next. Ask that, and treat the difference between a real problem and a preference as the frame for whatever you find.
