1. Maybe there is something wrong with the banking system. For example, some banks are upgrading their systems. There may be something wrong with the system, which will lead to the inability to deduct money according to the correct process. Don't worry about this situation, as long as the upgrade is successful, it will be automatically deducted.

2. There is another reason. Maybe the bank card itself is abnormal. For example, if the account is frozen, the deduction will also fail.

3. The bank will deduct money at any time on the repayment date of the mortgage, which may be in the morning, afternoon or evening.

1. A normal mortgage loan can usually reach up to 70% of the transaction price of the house, and the longest loan period that everyone can enjoy is 30 years, so even if the house price is high, most small partners can afford it. Housing loan is the first choice for many families to buy a house. Can I change my password on my bank card? The password of the mortgage bank card can be modified, and whether it is changed or not will not affect the mortgage deduction. Generally, mortgage deductions are withheld by banks. At the time of loan, the bank will sign a bank withholding agreement with the borrower, and the bank will automatically deduct money from the mortgage card on the repayment date without entering a password. However, it should be noted that the status of the mortgage card will affect the deduction. Some people accidentally lost their mortgage card, so they went to the bank to report the loss and then reissued the card. You know, banks can't deduct money from a card that has been reported lost. Therefore, in order to avoid overdue mortgage, everyone must change the mortgage card into a new one before the bank deducts money.

2. The bank repayment method is as follows:

1. Equal principal and interest repayment method: add the interest generated by the borrower during the loan period to the total loan principal, and then distribute it evenly to each month, and repay the same amount of funds every month.

2. average capital repayment method: the borrower repays the principal in equal amount every month, and the loan interest is calculated according to the remaining principal, and the interest is reduced by stages.

3. One-time repayment: within the stipulated repayment time, the principal and interest of the loan shall be paid off in one lump sum.

4. prepayment: apply for repayment of the remaining debts or all debts before the expiration of the loan period.
