Hello, according to the loan policy of Shanghai Housing Provident Fund, the following three conditions are required to apply for using the provident fund loan:

Self-occupied housing with ownership in cities and towns of this Municipality;

Before applying for a loan, the housing provident fund shall be paid continuously and normally for 6 months;

The borrower's family has no outstanding housing provident fund debt.

According to the above requirements, if your first housing provident fund loan is not paid off, you can no longer use the provident fund loan to buy a house. If you want to use it, I suggest you settle the previous loan first.

I hope my answer is helpful to you.
