I won't. Overdue will only produce late fees, and will not affect the mortgage. The late payment fee of every bank is the same, which is five ten thousandths of the overdue amount every day.

Overdue credit cards will generate late fees, that is, the minimum repayment amount will not be fully paid before the due repayment date. This fee is calculated on the basis of 5% of the outstanding part of the minimum repayment amount, with the lowest 5 yuan.

Assuming that the minimum repayment amount of the landlord's bill is 200 yuan, if it is not repaid at maturity, there will be a late fee on the bill next month, with the amount =200*5%= 10 yuan.

At the same time, it is necessary to remind the landlord that banks will generally report the repayment of customers' cards to the People's Bank of China truthfully, and overdue loans will be recorded in personal credit report, which will have a certain impact on future loans, such as mortgage loans and car loans. Therefore, it is suggested that the landlord try to return the minimum repayment amount of the card before the due repayment date, so that the bank will not count you as overdue.
