If you’re talking about debt consolidation through an agency like Consumer Credit Counseling, it actually damages your credit worse than a bankruptcy in the eyes of lenders. My wife works as a loan officer for Chase, she knows all about this stuff.
I don’t think banks will consolidate consumer debt per se. If you could arrange a loan whereby you pay off all your consumer debt, then repay the loan to the bank at an affordable monthly rate, I suppose that would work… but they say taking out a loan to repay another loan tends to snowball in a bad way. And if you’re behind on payments, odds are you don’t qualify for a new loan anyway.
Talk to a loan agent at your credit union or bank, let us know what they say.
