Why do most student loans involve a co-signer?
a. most students won’t be able to afford paying for their loans, and leave that responsibility to their co-signers.
b. co-signers were most likely college students themselves and understand what it is like to be a college student.
c. most students aren’t responsible enough to know much about any type of loans, so a co-signer is there to make sure everything is secure.
d. most students are young enough not to have much of a credit score or credit history, so a second party such as a parent or guardian can establish security of payment.
