For those of you who are saying "absolutely not!" What if someone's life was in danger? What if some animal's life was in danger? If you cosigned, you could save a life.
It kinda makes me sad reading all these people saying their "perfect" credit is more important than helping someone out. How do you explain that one to whoever you believe in?
And that's another thing too. If you can't afford to then fine, it's understandable. But if you could afford to take over the minimum payments if necessary then why not? If it's your gambling addict cousin, it's understandable. But someone who's borrowed money from you in the past and always paid it back? There has to be some sort of medium. Instead of absolutes.
IMO, if the person is an adult, out of college, and still needs someone to cosign for them, then that pretty much tells me that they are not going to be responsible in paying me back.
Once you lose your "perfect" credit score, it can take years to recover from it. Now maybe if I won the lottery, I wouldn't care about cosigning, but heh, I'm far from rich and fully supporting another adult.
