I have to wonder... I know everyone says to pay off unsecured (credit card) debt first, but if the time comes when you can't make your payments, what would happen? A lower credit score? they can't take any of your possessions away. If you had the $$ to pay off debt, and used it to pay off secured debt, that would save you from losing your house or car.
I'm thinking it might come down to: Do you want to keep your house, or your credit score?
We once bought a $3,000 car on a credit card. It was one of those 2.9% for life deals. We didn't use the card for anything else - treated it like a loan, so never had to worry about the "we'll apply your payment to the lowest rate charges first" clause. We paid less interest than a car loan, and had the title free & clear.
