Having good credit is on,ynoart of the “getting a loan in your own name” equation. If your son doesn’t have sufficient income and assets as collaterol, he will not get a loan in his own name.
The lending institutions want to be certain that the person has the means to pay the loan back. Without sufficient income, that’s just not going to be a happening.
I will add…owning a car when one NEEDS money might not be the best plan. Cars take money to maintain and use. Why wouldn’t he use that money towards college costs?
