Because your loan procedures have been completed, you have entered the repayment period. You changed your name and date of birth according to law, but it did not change the identity of the borrower, nor did it prevent you from continuing to repay the loan with the passbook opened with the original name until the creditor-debtor relationship was terminated.

But the key point should be that the name change is different from the records in the purchase contract or agreement, which will bring trouble to the property right certificate. Therefore, it is suggested to hold valid documents as soon as possible, first apply to the loan bank to change the original name to a new name, so as to facilitate repayment with the changed new name and avoid it, and then apply to the real estate trading center to change the name of the title certificate.
