Hi, I’m new here, but thought I’d give my input. I wouldn’t co-sign a loan, but would maybe suggest to your sister or her husband if possible, to get a part time job and put all of the money from that towards paying off her debt. I know this probably isn’t a popular idea, but if she did this for a while, she could really get somewhere.
Also there is a program I have information on (I’ll have to dig it out and could post it later) that tells you how to pay off bills in the most efficient way. If you’ve ever heard of Mary Hunt, she also has some good information on paying off debt. Kathy M
