Viewing recommendations

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.
  • Test water pressure and temperature at the tap, in the bathroom and kitchen, for at least a minute.
  • 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.
  • Knock on a neighboring gate and ask about noise, pets, flooding, or other issues common in the area.
  • 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 exactly where you'd park: a spot in the yard or garage, or street parking, and how crowded the street gets in the evening.
  • Ask what heating system is in place (own boiler, wood, gas) and request the last winter month's bills.

Neighborhood recommendations are derived from public OpenStreetMap data and may be incomplete. Checking in person is still what matters most.
