It is best not to buy this kind of house. It should be said that houses built on the top floor will not have real estate licenses. If you have a real estate license, it may be fake. Moreover, when the time comes, the housing management department will say that it is an illegal building and show you those books. At this time, you have no reason not to let others open it, so you'd better not buy this kind or buy it cheaply. No guarantee!
