In my experience the paying the lease (or whatever the money due is formally called) is the least controversial part of it. You'll have more problems with the owners of the apartments. (So all the problems of the dreaded HOAs, exist for every building if it's owned by a group - which is quite usual in Europe.)
But these are very low-level problems, and they tend to sort themselves out pretty quickly (in ~5 years, let's say, if the building needs a renovation and the owners were not too keen on participating and saving for it beforehand).
