Well, by those numbers it is doable BUT they would be on the Dave Ramsey Beans and Rice budget for the entire time they are on that schedule. I bet someone as stupid as this couple is not going to sit still for 30 years paying off their draconian debt burden which they created themselves.
Sorry, I have no sympathy for them or their lenders...go into chapter 13 and live with the consequences, in a 1500 apartment rental they can afford and a beater for a car.
They could rent out the condo for additional income to pay off their loans...
