Need to issue: the provincial provident fund deposit certificate, as well as the borrower's off-site loan income certificate and the housing provident fund deposit certificate (the above certificate, when you go to the developer to buy a house, the developer will give you a model to tell you how to do it). You also need the original and photocopy of the household registration book and the original and photocopy of the ID card. That's about it. If you need any materials, you will know where you buy a house and they will help you.
