Legal analysis: relay loan is the abbreviation of personal housing relay loan. Relay loan refers to a housing credit product in which children (or children and their spouses) are the owners of the houses purchased, and both parents or one of them and their children are co-borrower, and the loans are used to purchase houses. Agricultural Bank of China and China CITIC Bank have launched relay loan business. In the relay loan business, the child is the owner of the house purchased, and both parents or one of them and the child can purchase housing credit products as co-borrower. In other words, the bank can calculate the monthly repayment amount according to the sum of the accumulated income of all borrowers, thus increasing the loan amount and realizing the dream of buying a house through the joint efforts of father and son. The advantage of relay loan is that it can appropriately extend the age of the borrower and the loan period, and it is not limited by the prescribed upper limit; The disadvantage is that there may be disputes between parents and children because of housing property rights, or disputes between heirs because of inheritance and disposal. However, applying for personal housing "relay loan" requires certain conditions: both parents and children in co-borrower have stable jobs and incomes, and the sum of co-borrower's incomes can repay the loan principal and interest, and the older parents are not over 60 years old. Regarding the loan interest rate, if the house purchased is the child's first house, it can be implemented according to the first housing loan interest rate.
