Yes, according to the latest announcement of the central bank, each user usually has only one chance to change the mortgage interest rate. If the user previously changed the interest rate to LPR fixed interest rate or LPR floating interest rate, it cannot be changed again after the change. However, if the user is converted into LPR interest rate in batches by the bank, if the user is not satisfied with the current change, he may have the opportunity to change the interest rate. The changed interest rate is still LPR fixed interest rate and cannot be changed to the previous mortgage interest rate.
