the public maintenance fund specified by the state is 2%, the deed tax is 1.5%, and the stamp duty is 5/1. The rest of the fees are collected by the real estate company itself. Of course, the supporting fees or occupancy fees vary from place to place. This is how much the developers set by themselves, generally not exceeding 5, yuan, mainly including the pre-paid fees for water and electricity when they move in, or some need to open cables, gas or other fees. Developers will take this as a threat, and they will not do the house book unless they pay it, but in fact, they only need to pay the deed tax, public maintenance and stamp duty when they go to the real estate hall to handle the house book.
