Specifically, the following points need to be explained:

1. Credit record damage: overdue repayment will lead to personal credit record damage, which will be valued by financial institutions. The borrower's credit score may drop sharply, which will increase the difficulty of applying for loans in the future.

2. Difficulties in bank approval: When banks consider approving loans, they usually conduct credit checks on borrowers. Borrowers who are overdue for many times may not pass the strict review requirements because their credit status does not meet the risk control standards of financial institutions.

3. Rising interest rates: Even if some banks are willing to provide loans to borrowers who are overdue for many times, they tend to charge higher interest rates for fear of risks. High interest rates will increase the cost of loans and increase the repayment pressure of borrowers.

To sum up, many overdue loans will damage the borrower's credit record and may encounter difficulties in future loan applications. Even if you can get a loan, you may face higher interest rates. Therefore, avoiding overdue repayment is very important for maintaining a good credit record and obtaining favorable loan conditions.
