When my Buddy's mom sold their house a few years back, the Realtor listed it as having a Gas water heater....I've been in that house, and it's "mechanical room" hundreds of times....there is no gas line running to the water heater...unless some one made one that looks just like Romex...Our old house, we had listed that it had propane gas and dryer. New buyer planned to bring his newly bought... electric ones. Good luck with that, what with 60A service. Somehow both he and his realtor missed that detail.
when it sold, the new owners flipped it, same error in the new listing... almost like they just did a straight cut and paste of the old one...
