We just didn't notice the switch at the walkthrough, it's one light switch in the entire house. It was taped with clear tape and we didn't even notice until my son decided to flip it. I am upset with the inspector but more so with the previous owners. They clearly knew there was an issue and didn't mention it at all. I fully intend to pursue any available action I'm entitled to. I do appreciate the advice as I'm unsure of my rights here.
