When Dan quit his job and went back to school to get his teaching degree, the Egglestons went from being a dual income household to a single income household. During this time, they didn't alter their spending habits. Instead, the couple purchased a brand new home they knew they couldn't afford. Their house payments tripled, and the couple says that's when they got into trouble. First, they cashed in Dan's 401k, quickly spending all $40,000 in savings. And when that was gone, they began living off their credit cards.
