S3E3 Saving A Money Pit

Courtney and Emily are under pressure to transform their incomplete basement into a high-quality apartment quickly. They took on an additional $100,000 mortgage to purchase their home, and without the extra rental income, they'll quickly deplete their savings trying to manage the hefty payments. If they can’t generate that income soon, they might have no choice but to sell the house.
