This applies regardless of leasehold or freehold.
shared freehold is a nightmare and I agree with pp saying it's amazing how people think charges vanish if you share freehold.
happily, in my new place I am seeing signs of realism. I pointed out to someone that the mgmt comapnies would all pack up if they didn't make a profit and she said "good point". In another experience, I've had to tell one mgmt co that certain jobs didn't need doing - but they have to serve notice anyway so if they're trying to raise money for their mates to do an unneeded job, they get stopped that way.
I'm not entirely sure what's happened in some of the places where people have been fleeced but often people don't seem to know they have the right to look at invoices etc
I also pay monthly so if they go bust, less of my money goes with them.
it tends to be older buildings that have huge sink funds I think? and my share of freehold had one too. After that, I was in a flat that was 6 years old when bought and now a new build.
edit - @tropicalroses there will always be people who want to live in flats rather than houses for a range of reasons. I wouldn't worry until you see some draft legislation and it will take ages.
