Simson, welcome to the forum.
A debt consolidation loan usually requires some type of collateral(but not always), sometimes a home equity loan, or you can go through a bank or other financial institute. They pay off all your creditors, then you only owe them.
Debt consolidation is when you go through a company that works with your creditors to lower your interest rates, you mail in one payment to the company, and they dispurse the money to each creditor each month...but they do not pay off all the creditors in this case. You are usually required to close all accounts, and basically you are having a middle person make all your payments and communicate between you and the creditors.
A few years ago I got a consolidation loan through GE Capital Financial. We gave them all our account info and they paid off all the debts, then we just paid them. It was a great deal, only they did not require us to close our accounts, so my husband just ran them back up. Stupid, yes. So, regardless of which you go with, be smart and close your accounts, then there is no temptation there.
Hope this info helps.
