This.Why on earth would you want to make someone else's payments for them??
If you don't have any credit, save your money and pay cash for a bike. Paying a monthly payment on time for someone else is stupid. It's not going to build you any credit, and it's going to be eating your income up so that you can't try to get any other loans.
I wouldnt as the owner unless the bank will allow it, Now if you just consider it a rental, I guess after it gets crashed or stolen, you can just give it back or walk away.I just turned 18 so I have absolutely no credit established. Would taking over someones payments on a bike be a good alternative? What should I know before I go about doing something like this?
