i agree with the last post, i live in a victorian conversion (two flats) i own freehold,and so does the other flat but there is a share with maintenance etc on whole property i am on ground floor but shera cost of roof with upstairs. Same as if there are gutter or water mains issues on ground level the cost is shared. you normally only have a lease on larger blocks of flats but these again can be bought out. building insurance etc on smaller converted properties is shared. As the above post said buying a flat unless in a 10 plus block i.e say is better to be freehold to have more say.
