Wrong. You'll end up borrowing for your closing costs to be rolled in, and a higher rate of interest for the HELOC. The guy following Dave Ramsey should just stay the course.
And I'm betting if he's $30k in CC debt he's probably paying more than $5,500/year in interest.
I will agree if this primitive is actually following the Dave Ramsey model, which I believe entails cutting up your credit cards and getting with the credit card company to get them to stop charging interest and to work out a principle-only payment plan.
But if this primitive is still paying $5,500/yr in interest, and it's going to take him 3 or more years to pay off the $30K debt, he might actually be better off with a HELOC.
My mortgage/finance company used to work with people trying to do debt consolidation all the time. Working the math, setting a budget, and making a plan was never the issue. It was always getting the customer to follow the plan where the problems came in.
But as far as high risk credit cards for people who have ruined their credit, it's a no win as far as PR. Offer it and the people go into more debt and the credit card company gets blamed. Don't offer it, and they get blamed for not being willing to help. The general public starts clamoring for these credit card company's to offer the poor very low rates, like 1/2% or 1% interest. First of all, the market isn't built that way. But even if you were to defy the market, the problem isn't the rate, the problem is the spending habits of those who are in that position by, as the primitive said, "not thinking about it."
