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.
  • 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.
  • 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.
  • Check the condition of the fence, yard, and sidewalk out front: who is responsible for upkeep, and whether there are any boundary disputes with neighbors.
  • 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.
