Viewing recommendations

What's worth checking in person before deciding.

  • Test water pressure and temperature at the tap, in the bathroom and kitchen, for at least a minute.
  • Schedule a viewing on a weekday too, between 6:00 and 7:30 PM, the window when the building is busiest: neighbors, parking, elevator.
  • Look at the stairwell (cleanliness, smell) and the association's notice board: unpaid dues, conflicts, recent decisions.
  • Ask for the latest maintenance bill from a winter month, not a summer one: that's where the real cost of living there shows up.
  • Knock on a neighboring door and ask two things: what bothers them most often, and what work is planned for the building.
  • Ask specifically where you'd park: is there paid city parking, who currently holds it, what the permit costs, and how long the waitlist is.

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