Hello, the provident fund paid by Shanghai cannot be used to repay the mortgage. At present, provident fund loans in most cities are still linked to household registration. Buying a house in a different place is also an act of buying a house. You can withdraw the provident fund. I bring my ID card, co-branded card, real estate license or other proof materials and valid bills to the management department of the housing provident fund center where you paid the provident fund.
