Always trips me up hearing about how house sales work in the US. Soo inefficient and many people involved that need their fees. And is the inspection done after, by the buyer?? Why isn't it done by the seller and included in the ad? That's mandatory here. Sounds like a recipe for disaster and conflicts.
