You need to have a tax payment certificate for at least one year and a household registration book. ID card, unit certificate. Proof of salary income, copy of unit business license. One year's salary bank statement. Proof of marriage. If you are divorced, you must submit a property division adjustment letter from the marriage registration office, whether there is a car loan, and whether there is a record of credit card debt. I just bought a house and the procedures went smoothly. Good luck!
