For privacy purposes it's better to buy an unit in a condo, than a house. In a house your neighbors can easily look out their windows and see who visits you, whose car is parked in front of your house. In a condo it's much harder because the same main entrance is used by many people and it's difficult determine which unit a visitor entering the main entrance is going to, so it's harder to connect the dots.
