“Buying that first house had a snowball effect. Almost immediately, Mitch and Gina bought two adjacent lots for even less and, with the help of friends and local youngsters, dug in a garden. Then they bought the house next door for $500, reselling it to a pair of local artists for a $50 profit. When they heard about the $100 place down the street, they called their friends Jon and Sarah.

Admittedly, the $100 home needed some work, a hole patched, some windows replaced. But Mitch plans to connect their home to his mini-green grid and a neighborhood is slowly coming together.”
