When applying for a mortgage loan, as long as the cardholder fails to repay the loan three times in a row or six times in two years, and the overdue amount is not large, if the debt is paid off after the deadline, the bank will still be happy to approve the loan, but the loan interest rate will increase, that is, the benchmark interest rate will rise. But the specific floating range depends on your overdue times and bank regulations.
However, I heard that credit cards can go up by 5% once overdue, 10% twice overdue, and some even go up by 15%. Although 5% doesn't seem like much, if you want to calculate it, it will be tens of thousands of loan interest. This is only online data, uncertain, subject to the bank.
