If it is two people (husband and wife), you need to submit a copy of marriage certificate, ID card, household registration book, income certificate and household registration certificate. If you have not settled down (that is, there is no household registration book), you only need to provide proof of household registration. If you are not married, you don't need a marriage certificate.

If you go through the formalities, the intermediary will help you. You don't need to worry about it. I can give you some attention. When filling in various forms (read them carefully before filling in), the agent may ask you to fill in an agency fee. You can't fill this in, or you will lose thousands of dollars in vain. The agency fee will be clearly paid when signing the house sales contract, which is 2% of the purchase price, and there is no other fee. Some black-hearted intermediaries will ask you for a sum of money, saying it is the last intermediary fee. Without this, the landlord should be careful!

I hope it helps you.
