A property viewing is short. The agent is friendly, the rooms are staged, and the whole thing is designed to make you feel something before you have had time to think. Twenty minutes later you are back outside, trying to remember whether the second bedroom actually had a window.
A checklist fixes that. It keeps you objective when the staging is working on you, makes different properties genuinely comparable, and stops you from forgetting the boring-but-expensive things while you admire the kitchen. This guide walks through what to check at every viewing, room by room, plus the red flags that should give you pause and the green flags worth chasing. Save it or print it and take it with you.
Before You Go
Do a little homework before the viewing so you arrive with sharper questions. Look at the listing photos and note what is conspicuously missing: no bathroom photo, no exterior shot, no kitchen. Absence is information. Check how long the property has been on the market and whether the price has dropped, both of which hint at demand and negotiating room.
Look up the street on a map, check the energy rating if it is published, and note the orientation so you know which rooms should get light and when. If you can, time your visit for when you would actually be home, so you experience the real light and noise rather than the quietest moment of the day.
The Exterior and Structure
Start outside, because the most expensive problems usually live in the structure. Look at the roofline for sagging or missing tiles, and at the walls for large cracks, especially stair-step cracks around windows and doors or anything wider than a coin, which can signal movement. Check that gutters and downpipes are intact and directed away from the building.
Red flags: fresh render or paint on one isolated patch of an old wall (often hiding damp or a crack), a roof that visibly dips, damp tide-marks at the base of external walls, and trees growing very close to the foundations.
Green flags: a recently and fully replaced roof, sound pointing on the brickwork, level floors when you look along them, and a building that has clearly been maintained rather than patched.
Damp, Water, and Ventilation
Damp is the problem buyers most often miss and most regret. Use your nose first: a musty, earthy smell is the clearest early warning, even when nothing is visible. Then look at the lower corners of external walls, behind furniture and curtains, around window reveals, and at ceilings beneath bathrooms for staining or bubbling paint.
Red flags: a strong air-freshener smell (sometimes used to mask damp), black mould in corners or around windows, peeling wallpaper, and furniture pushed tight against walls as if to hide them. Green flags: trickle vents on the windows, an extractor fan in the bathroom and kitchen, and dry, clean wall bases throughout.
Inside the Rooms
Open things. Open and close every window and a few internal doors to check they are not sticking, which can indicate movement or swelling from damp. Look at the ceilings for cracks and stains, and along the floors for noticeable slopes. Press gently on tiled walls in bathrooms to feel for movement behind the tiles.
Count the storage, the power sockets, and the radiators, since these are easy to overlook and annoying to add later. Be wary of a single freshly painted wall or a rug placed oddly in the middle of a room: both can hide something. Green flags: sound double glazing, generous natural storage, and rooms that feel as usable as they look in the photos.
Services and Systems
The systems are where a cheap-looking property gets expensive. Ask the age of the boiler or heat pump and when it was last serviced. Turn on taps to check water pressure and how long hot water takes to arrive. Look at the fuse board: a modern consumer unit suggests updated wiring, while an old one can mean a full rewire is due.
Check the energy rating, since heating an inefficient home is a recurring cost that does not show up in the asking price. Note the type of heating, the insulation where you can see it (loft, windows), and any sign of past plumbing leaks under sinks and around the boiler. For apartments, ask what the service charge covers and when the building was last renovated.
Light, Noise, and Orientation
Light and noise shape daily life more than almost anything on the listing. Note which way the main rooms face: south and west bring more afternoon light, north-facing rooms stay darker and cooler. Stand still for a moment and just listen, for traffic, trains, a school, a busy bar downstairs, or thin walls between neighbours.
Red flags: every viewing scheduled at the same quiet time of day, windows facing directly onto a main road, and rooms that feel dark even at midday. Green flags: bright, dual-aspect rooms, a quiet street, and double glazing that noticeably cuts outside noise.
Location and Neighbourhood
The property is fixed, but so is everything around it. If you can, visit the area at different times: a calm street on a weekday morning can be very different on a Friday night. Walk to the nearest transport, shops, and green space to time them honestly rather than trusting the listing's description. Check parking, mobile signal inside the property, and the state of neighbouring buildings, which tells you how the area is trending.
For a cross-border purchase, this is harder to do in person, which makes the listing data and photos do more of the work. Look closely at what the surroundings reveal in the images, and ask the agent specific questions about noise, parking, and the immediate neighbours.
Questions and Paperwork
End every viewing with the same set of questions, so your notes stay comparable. Why is the owner selling, and how long have they been there? How long has it been on the market? What exactly is included in the sale? Are there any planned works, disputes, or known issues? For older or extended properties, ask whether all work has the required permits and whether the registered floor area matches what you walked through.
For apartments and anything with shared ownership, ask about service charges, the state of the building's reserve fund, and any upcoming major works. The answers are part of the price, even though they never appear on the listing.
The Quick Red-Flag and Green-Flag Summary
Red flags worth pausing on: a musty smell or heavy air freshener, fresh paint or render in isolated patches, sticking doors and windows, sloping floors, large or stair-step wall cracks, black mould, an old fuse board, vague answers about why the owner is selling, and a property that has sat on the market for a long time with no obvious reason.
Green flags worth chasing: a recently replaced roof or boiler, a strong energy rating, dry walls and good ventilation, bright dual-aspect rooms, sound double glazing, honest and detailed answers from the seller, and a building that has clearly been looked after rather than dressed up for sale.
Viewing From Abroad
If you are buying in another country, you often cannot drop in for a second look, so the first filter happens online. This is where good listing data earns its keep. Read the full description, zoom into every photo, and treat missing photos as questions to ask. A first viewing by video call, with the agent walking you through slowly while you run down this checklist, can save a wasted flight.
It also helps to pre-screen widely before you travel, so every trip is spent on genuine contenders. One Place indexes millions of active listings and hundreds of millions of property images across more than half of Europe, so you can shortlist in plain language from home, then take this checklist to the viewings that actually make the cut.
FAQs
What should I check first when viewing a house?
Start outside with the structure: the roof, the walls, and any large or stair-step cracks, since these are the most expensive problems to fix. Then use your nose for damp before you are distracted by the staging inside. Light, noise, and the systems (heating, water pressure, electrics) come next.
What are the biggest red flags at a property viewing?
A musty smell or an overpowering air freshener, fresh paint or render on isolated patches, black mould, sticking doors and windows, sloping floors, large wall cracks, and an old fuse board. Vague answers about why the owner is selling, or a property that has sat unsold for a long time with no clear reason, are also worth probing.
What are good green flags when buying a house?
A recently replaced roof or boiler, a strong energy rating, dry walls with good ventilation, bright dual-aspect rooms, sound double glazing, and a building that has clearly been maintained. Honest, detailed answers from the seller are a green flag in themselves.
Should I view a property more than once?
Yes, where you can, and ideally at different times of day to test light and noise. A property can feel completely different on a quiet weekday morning versus a Friday night. If a second in-person viewing is not possible, a video walkthrough with the agent is a good substitute.
How do I inspect a property when buying from abroad?
Lean on the listing data and photos for the first pass, then arrange a video viewing where the agent walks you through slowly while you work down a checklist. Pre-screen widely online so any travel is spent only on genuine contenders, and commission a local survey before you commit.
Do I still need a professional survey if the viewing looks fine?
Yes. A viewing checklist helps you compare properties and spot obvious warning signs, but it is not a substitute for a professional survey, which is not legally required in most European countries but is strongly advisable for older buildings or anything where you cannot verify the construction history.
A viewing is a sales environment, and a checklist is how you stay objective inside it. Check the structure before the styling, trust your nose on damp, listen for the noise the photos cannot capture, and ask the same questions every time so your shortlist stays honest.
