Write the names of two people. The main lender refers to the borrower, that is, the main person in charge of the loan, and the co-lender is also called the borrower. First of all, it requires that the lender must be an immediate relative, that is, the relationship between husband and wife, children and parents. However, if there is a sub-lender, two names can be written on the real estate license, which is also responsible for the later loan.
