So far so good, but the guy was squatting(?) in the bottom unit of a duplex owned by a "recluse" and renovating the exterior. The recluse assured us it would be done in 6 months. 2 years of constant "construction" later he's disappeared and we find out she's died.

He left meat out for his outdoor cats (who also left us gifts). His non-code electrical work included running a non-outdoor rated extension cord to the street for his buddy sleeping in a car (the electrical was our concern), and he consistently undermined the hill our homes shared.
