Nobody warns you about the smell. That's the thing I remember most from the first house I nearly bought: a faint sweetness in the back bedroom that I only noticed on my third visit, when the sun had been hitting that wall for hours. The owner had painted over it twice. I walked away three weeks and one survey later, and I still think about the £4,000 I almost spent on a damp problem nobody had mentioned.
House viewings are theatre. The lights are on, the bread is in the oven, and you've got twenty-five minutes to work out whether the biggest purchase of your life is a sound decision or a very expensive mistake. The questions you ask when viewing a house matter far more than the décor you're looking at. Here's what I've learned, sometimes the hard way.
Key Takeaways
- Ask about running costs, not just the asking price. Council tax, energy bills, and service charges can swing your monthly budget by hundreds.
- Always ask why the owners are selling and how long the property has been on the market. Motivation tells you about negotiating room.
- Red flags cluster around moisture, structure, and paperwork. If you spot one, get a surveyor in before you fall in love.
- Visit at different times of day. A house that feels calm on a Saturday morning can sit on a rat run at 8am on a Tuesday.
- Put your questions in writing to the agent. Verbal answers evaporate the moment you leave.
The questions to ask when viewing a house (and why most people ask the wrong ones)
Most buyers spend the viewing asking about the boiler's age and whether the appliances stay. Fine, but that's not where the money hides. The real cost of a house sits in the things nobody puts on the listing: drainage, heating efficiency, the roof, and whatever the neighbours do at 6am on a Sunday.
I learned this after viewing eleven properties in one spring. The one I ruled out fastest had a beautiful kitchen and a single-glazed extension that would have cost me a fortune to heat. The one I nearly missed had a scruffy hallway and a brand-new boiler with a ten-year warranty. Priorities, not appearances.
The questions that actually save you money
Here's the short list I now hand to friends before they view anything. Ask these in the first ten minutes, while the agent is still eager.
- What are the annual running costs? Ask for a real figure for electricity, gas, and water over the last year. Don't accept "it's reasonable."
- How old is the roof, and has it ever been replaced or repaired? A roof nearing the end of its life is a five-figure problem waiting to happen.
- What's the council tax band, and what are the service charges if there's any shared maintenance?
- Has the property ever had damp, subsidence, or flooding? Ask directly, then look for the evidence yourself.
- Which fixtures and fittings are included, and which are the owners taking?
- Is the property freehold or leasehold, and if leasehold, how many years are left on the lease?
That last one catches people out constantly. A lease under 80 years can make a property hard to mortgage, and extending it isn't cheap. If the agent hesitates on the answer, that hesitation is your answer.
What to look for when viewing a house: a checklist that holds up
Questions and observation go together. You can ask all the right things and still miss a cracked lintel because you were admiring the garden. So walk the property with a short checklist in mind.
- Moisture: look at ceiling corners, behind furniture, and around windows for staining or peeling paint.
- Structure: any diagonal cracks wider than a coin edge deserve a surveyor's eye, not yours.
- Electrics: ask when the consumer unit was last updated. Old fuse boxes are a warning, not a dealbreaker.
- Windows: single glazing and draughty frames mean higher bills and future replacement costs.
- Drainage and water pressure: run a tap, flush a toilet, and ask about any history of blockages.
- Neighbourhood: visit the street at a different time. Rush hour and school pickup tell you more than any brochure.
Take photos, and take notes. By your fourth viewing, every kitchen will blur into the same kitchen, and you'll be grateful you wrote things down.
What is the 3-3-3 rule for buying a house?
You've probably seen this floating around, and it's worth being honest: there is no single official "3-3-3 rule" for buying property. Different versions circulate, and they don't all agree. The most common one I've come across is a budgeting framework: aim to hold the property for at least three years, keep your deposit and purchase costs within a sensible band, and stay comfortably inside a repayment range rather than stretching. Another version is about visits and research: view the property three times, compare three neighbourhoods, and gather three quotes before committing to any major work.
My honest take? The numbers in these rules matter less than the habit they encourage. The underlying idea is discipline: don't buy on impulse, don't stretch your budget to the edge, and don't assume you'll sell quickly if you change your mind. Transaction costs alone can eat a significant chunk of any short-term gain, so the "three years" figure, in whatever form it takes, is a useful reality check rather than a law of nature.
Should you follow it?
Treat it as a conversation starter, not a formula. If a rule pushes you to ask harder questions about your own finances and timeline, it's doing its job. If it makes you feel you've ticked a box and can relax, ignore it.
What is a red flag when buying a house?
Red flags are rarely dramatic. They're quiet. A patch of fresh paint on one ceiling corner. A musty smell the agent blames on the weather. A seller who's vague about why they're leaving after only a year. Individually, none of these is fatal. Together, they're a pattern.
Here are the ones that should slow you down:
- Structural cracks that are wide, diagonal, or appear near doors and windows.
- Persistent damp or mould, especially in corners of rooms or behind furniture.
- Rising damp along the base of walls, often masked by furniture or a fresh coat of paint.
- A consumer unit or wiring that clearly hasn't been touched in decades.
- A lease with fewer than 80 years remaining.
- A seller in an unusual rush, or a price that keeps dropping.
- Neighbours who are unusually keen to tell you about the area. Sometimes that's friendly. Sometimes it's a warning.
None of these mean "don't buy." They mean "get a surveyor, get a quote, and price the problem in."
The question everyone forgets: why are they selling?
Ask it plainly, and listen to how the answer comes out. "We're upsizing" is straightforward. "It's complicated" deserves a follow-up. A seller who's been trying to move for a year may be far more flexible on price than one who listed last week. Motivation is one of the few genuine levers you have as a buyer, and it costs nothing to ask.
Questions to ask before you make an offer
By the time you're serious, your questions should have shifted from curiosity to verification. This is where you confirm what you've been told, in writing.
| Question | Why it matters |
|---|---|
| How long has it been on the market? | Long listings suggest overpricing or hidden issues. |
| What's the full cost of ownership? | Tax, service charges, and utilities shape affordability. |
| Has anything been replaced recently? | New boiler, roof, or windows can save you thousands. |
| What's included in the sale? | Prevents disputes over fixtures after you've committed. |
| Have there been any disputes with neighbours? | Sellers are legally obliged to disclose many of these, but ask anyway. |
Write them down. Email the agent. A paper trail protects you if something surfaces later that you were told didn't exist.
The quiet questions that rarely make the list
Some of the most useful questions have nothing to do with the building. Ask about parking permits and waiting lists. Ask how the bins are collected and whether there's ever been an issue with drainage on the street. Ask what the broadband speed actually is, not what the listing claims. I once viewed a flat where the advertised "high-speed internet" turned out to be a connection the whole building shared. The owner shrugged when I asked. That shrug saved me a year of frustration.
And ask about noise. Traffic, trains, pubs, and early-morning deliveries don't show up in photos, but they shape how a house feels at 6am and 11pm alike.
The question you should ask yourself
Amid all of this, there's one question no agent can answer for you, and it's the one that matters most: can you actually picture your life here? Not the version with the bread in the oven and the sun streaming through the window. The real one, on a wet Tuesday in February, with a leaking gutter and a boiler that's making an odd noise.
If you can picture that version and still want it, keep asking questions. If you can't, no checklist will change your mind. And honestly? That instinct is worth more than any list I could give you.
