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.
  • Test water pressure and temperature at the tap, in the bathroom and kitchen, for at least a minute.
  • Ask what heating system is in place (own boiler, wood, gas) and request the last winter month's bills.
  • Ask to see the construction documents (permit, sign-off) and check for visible cracks on the facade or in the attic/basement.
  • Knock on a neighboring gate and ask about noise, pets, flooding, or other issues common in the area.
  • Check the roof, gutters, and downspouts for signs of leaks or recent repairs, especially if it has rained recently.
  • Schedule a viewing in the evening too, on a weekday, to see street traffic, streetlights, and how quiet the neighborhood is after 8 PM.

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