I don't have much faith in home inspectors. We bought our house in Las
Vegas in 2000 and of course it was inspected. The guy grumbled about
having more than one wire under each screw in the breaker box, but let
it pass. He better not ever look at mine here... Anyhow, the people
that had the house before had put out outside flood lights and ran light
16 gage zip cord across the rafters in the garage, a real fire hazard
and he never said a word about that.
