First of all, how much money can be used in the provident fund account depends on your monthly repayment. You can only withdraw the total repayment amount for one year at most, and you can't withdraw the excess. If you want to use it all directly for repayment, it is impossible, and you can't withdraw your provident fund until you retire, unless you refinance.
In addition, to get the provident fund, you must first check the account number of the provident fund in the unit finance, then print the repayment details in the loan bank, and finally bring the house sales contract, loan contract, ID card, etc. Go to the provident fund center. If the house is occupied, two people's certificates are needed.
