Re: Leasehold, fleecehold
Which is why Edinburgh Council (and perhaps other parts of Scotland) have:
a) Statutory Notice Scheme to enforce essential repairs (they organise the work and invoice the owners if the owners can't agree). There was a scandal previously where the Council officials were mandating all sorts of non-essential work and getting backhanders, but since exposed there's no incentive to schedule unnecessary work, so the scheme works, and;
b) Shared Costs scheme which reclaims the missed portions from the owners who failed to pay up. As long as a majority of owners have agreed to the works the missing owners are forced to pay up by the Council.
