After resigning, the original unit will seal the employee's provident fund account, which means that the payment will be stopped. If the new unit has established a housing provident fund account, it can go through the formalities of transferring the housing provident fund account and transfer the housing provident fund to the new unit account. If the new unit has not established a housing provident fund account, the housing provident fund account of the original unit can be sealed in the original unit or transferred to the fund center for centralized storage, which is managed by the fund center. The funds in the provident fund account can be collected by the purchase contract. As for whether you can buy a house with a provident fund loan, it mainly depends on the balance and deposit of the employee provident fund account. The payment standard is different in each region. For example, the Nanning provident fund loan needs to be paid for six months continuously, but the loan can also be calculated by the balance in the provident fund account. Therefore, you need to consult the local provident fund center in detail.
