I'm a little out of my league on this, since it's been a while since I had to deal with all this. A friend has asked me to help with tuition, which I am happy to do. However, I thought a good way to kill two birds would co-sign a private student loan, to help him build up some credit. I know that I am going to pay the loan-- so, I'm curious-- will it show on his credit report if someone else pays the loan or makes a large payment to pay off the loan? And will this hurt his credit somehow? I simply don't know how this works. I'd rather not give him the $ to pay it himself, I'd like to ensure it's properly paid, but I want to know if there will be a notation that the co-signer paid, and as such, it makes it look as if he defaulted. Thanks so much.
