Viewing recommendations

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.
  • 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.
  • Ask to see the construction documents (permit, sign-off) and check for visible cracks on the facade or in the attic/basement.
  • Check the sewer connection (public network or septic tank) and the water source (public network or well), including pressure and water quality.
  • 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.
