Do not co-sign on a loan unless you can afford the loan payment! When you co-sign on a loan, you are just as responsible for the debt as the primary borrower. If the primary borrower does not make the required payments, then the lender will look to you to make the payments. If you do not make payments, then the lender may report bad credit information about you to the credit reporting agencies, refer the debt to a collection agency to attempt to collect from you, and even sue you to collect the debt.
