What's worth checking in person before deciding.
- Semi-detached or row house: the shared wall matters. Listen from the room adjoining the neighbor's side and ask whether any structural work has been done there.
- 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.
- Schedule a viewing in the evening too, on a weekday, to see street traffic, streetlights, and how quiet the neighborhood is after 8 PM.
- Check the sewer connection (public network or septic tank) and the water source (public network or well), including pressure and water quality.
- Knock on a neighboring gate and ask about noise, pets, flooding, or other issues common in the area.
- Ask to see the construction documents (permit, sign-off) and check for visible cracks on the facade or in the attic/basement.
Neighborhood recommendations are derived from public OpenStreetMap data and may be incomplete. Checking in person is still what matters most.
