House hunting means walking through a lot of properties in a short space of time, and it's easy to get swept up in the things that look good — the kitchen, the natural light, the backyard. But a few small visual cues can tell you a lot about what's actually going on behind the walls, and they're worth pausing over before you get too attached to a place.
None of these automatically mean walk away. They're signs worth a closer look, and that's exactly what a formal pre-purchase inspection is for. But if you're touring properties yourself, here's what we'd encourage you to keep an eye out for.
1. A patch of fresh paint in one specific spot
A freshly painted wall or ceiling isn't a problem on its own — plenty of sellers repaint before listing. What's worth noticing is a patch of new paint that doesn't match the rest of the wall, especially in an odd spot like low on a wall or in a corner of the ceiling. That's sometimes a sign of a water stain, crack or repair being covered up rather than fixed.
2. Doors and windows that stick or don't close flush
Try a few doors and windows as you walk through. If several of them stick, drag on the frame, or don't sit flush when closed, it can point to the building settling or shifting — sometimes completely normal for an older home, sometimes a sign of more significant movement. One sticky door isn't a red flag. Several, especially on the same side of the house, is worth asking about.
3. Musty smells or watermarks
A musty or damp smell, especially in a bathroom, laundry, or subfloor area, is one of the more reliable warning signs. Look up at ceilings and down at skirting boards for brown or yellow staining — even if it's been painted over, a slightly different sheen or texture in one patch can give it away. Moisture issues are usually fixable, but they're not always cheap, and they're worth knowing about before you sign anything.
4. Floors that feel uneven or bouncy
Walk the full length of a hallway or room and pay attention to how the floor feels underfoot. A soft, bouncy, or clearly sloping floor can point to problems with the subfloor structure or footings. It's easy to miss this if you're focused on the room's layout rather than the floor itself, so it's worth doing deliberately.
5. Cracks wider than a few millimetres, especially stepped ones
Almost every property has some hairline cracking — it's a normal part of a building settling over time and usually nothing to worry about. What's worth a second look is a crack wider than about 3-5mm, or a "stepped" crack that follows the mortar lines in brickwork in a zig-zag pattern. Those patterns can indicate structural movement, and they're exactly the kind of thing a structural inspection is built to assess properly.
Trust your eyes, but get a professional opinion
Spotting one of these signs doesn't mean a property is a bad buy — plenty of perfectly good homes have a sticky door or a hairline crack. What it means is that it's worth getting a second, trained pair of eyes on the property before you commit, so you know exactly what you're dealing with and can factor it into your decision with confidence.
