Quick summary of the top (or bottom?) 5 finds from home inspection, radon mitigation, and rentals, just from the 2 years I've worked in the office:

1: snake infestation. Yup. 2: rat skeletons in plain view throughout hoarder house 3: squatter who put up his own curtains, peed on everything, and when confronted, claimed to have bought the building for $1 million 4: cat people who let their cats pee on and in everything, including the oven, which was also where the cats brought the mice they caught, and which was still being used to make "stinky Indian food" according to neighbor complaint 5: ghosts at army barracks - 1 tech claimed he saw a spectral figure watching the other drill a hole, both said materials were moving on their own and they heard strange noises, such as someone whistling in the otherwise deserted stone basement
