Long-term loans are mainly used for some businesses with long payback period, such as housing loans, and the longest loan period is 30 years. Long-term loans usually have higher interest rates because the loan term is longer. According to the relevant regulations, after the borrower repays the overdue debt, the bad records will be counted from the date of paying off the loan principal and interest, and will be kept in the credit investigation for five years. After five years, the bad records will be eliminated, which means that the credit business will be affected within five years.
