What's worth checking in person before deciding.
- This is a house, not an apartment. Check the lot boundaries, car access, and how water drains from the yard after rain, including whether the neighboring lot sits higher and could send water toward the property.
- Test water pressure and temperature at the tap, in the bathroom and kitchen, for at least a minute.
- Ask to see the construction documents (permit, sign-off) and check for visible cracks on the facade or in the attic/basement.
- Schedule a viewing in the evening too, on a weekday, to see street traffic, streetlights, and how quiet the neighborhood is after 8 PM.
- Ask what heating system is in place (own boiler, wood, gas) and request the last winter month's bills.
- Knock on a neighboring gate and ask about noise, pets, flooding, or other issues common in the area.
- Check exactly where you'd park: a spot in the yard or garage, or street parking, and how crowded the street gets in the evening.
