So I'm in the process of buying a house. It's three stories on three lots and got a great deal. Threw the home inspection and walk threws, we noticed there were no lights in any of the rooms. Long story short, the fixtures are patches over the switches are there but dead because the wiring from them to the lights is knob and tube. All the outlets are romex basement is all romex and on circuit breakers. So basically he updates half the system and not the rest. It still has plaster walls so I'm not sure how he did the outlets but I'm not sure where to go from here.
