10. Short-term lets
Have a quick look on websites like Airbnb, Gumtree and Stayz to see if the building has entire flats for let for periods shorter than three months. If so, expect to have tourists, footie fans and bucks parties coming and going, damaging the common property and using the facilities that you pay for, making the kind of noise they would never get away with in a hotel, all to line one or two greedy owners’ pockets. Be afraid.
