I used to live in a nice, quiet purpose built flat with good neighbours. The only problem was the Factor's bills (In Scotland the management company is known as the Factor) which were extortionate. Even though we paid a monthly amount to the Factor if any work needed doing in any of the flats within quite a large complex the cost would be split between each flat. So, for example if the lift in another block needed a repair every flat in every block had to contribute payment. It became very expensive to live there.
