1. I am looking for a flat to rent. I see a number of documents issued by government departments are posted at the entrance of the building of the flat, but I don't know what they are. Will my interest be affected if I rent that flat later?

These documents may or may not affect your interest as a potential tenant.  Examples include various forms of statutory orders issued by the Buildings Department under the Buildings Ordinance (Cap. 123) mandating demolition and remedial works to be carried out before a specified time.  You should at least read the contents to ascertain what the documents are.  If in doubt, you should seek legal advice before you commit to any tenancy agreement with the landlord.
