So in April 2018, the Sullivans bought an old school bus for $2,800, and spent another $30,000 turning it into a proper home for their three kids. It took Brian and Starla one year. They had no experience in construction or renovating, so it wasn't easy. But they actually managed to find room for a full size bed, a kitchen with an oven, a washing machine, a toilet and even a bath tub for their three children. And best of all, they only pay $500 a month now.
