Pro tip: stop rolling negative equity into the next loan, that's why you're stuck at $640 a month
My coworker in Phoenix traded her $19k underwater SUV for a newer one and her payment went from $480 to $640 because the dealer just folded the old debt into a 72 month note, so ask for the payoff number in writing and pay down the gap first, has anyone actually gotten a bank to say yes to that?
