Thank you Linar for your respond.

Well, in our situation we are the builders, we are the once to do the renovations if necessary or hire the subcontractors to do them if we need electrician or registered plumber for example.Any other work my husband handles. Unfortunately in most cases the agents know that the block can be subdivided and all apartments sold individually. Do you know where I can read a bit more about the process and how it is done in terms of the legal site of things? Thank you again,
