Mortgage, as a large loan, is a major event in many lives, but if overdue, it has a negative impact on an individual ' s credit, the quality of the bank ' s assets, etc. This paper will be analysed from the perspective of credit, banks, and individuals。

The adverse effects of the mortgages

On the credit side, the overdue mortgage has a negative impact on the credit records of individuals. Banks usually record overdue information in the letter-writing system, which means that an individual ' s credit records will be spoiled. Credit records, on the other hand, are important for future borrowing, credit cards, insurance and so on, and late records can affect individuals ' workplace and social relationships。

On the banking side, delays in mortgages will negatively affect the quality of the bank ' s assets and cash flows. This is because, when a bank extends a loan, it usually makes other loans on the basis of the loan, and therefore delays in the loan lead to setbacks in other business processes of the bank. In addition, banks need to bear additional costs, such as default money and collection costs, which further reduces their profitability and competitiveness。

On the individual side, the overdue mortgage will have a negative impact on the individual. First, increased costs due to delays would further increase the burden on individuals. Second, delays may lead to judicial measures taken by banks, such as the seizure, auctioning of houses and so on, which will lead to loss of personal assets and a further reduction of credit. Finally, delays may even lead to the loss of a person ' s place of residence, which will cause great distress to the person ' s life。

In sum, mortgage delays not only affect personal credit, the quality of bank assets and cash flows, but may also cause many problems for individuals. Therefore, when buying a house, it is important to take account of its affordability and to avoid overpayment。
