Yeah, a lot of buyers want the seller to turn that old house into a new one for them, and then get really surprised when the seller says "no."
Our inspector identified a lot of things that needed attention, but only a couple of things that needed repair: one was a portion of the foundation (a few feet of sill plate needed replacement, and four pillars needed to be adjusted), and the other was the wiring (one circuit of knob-and-tube wiring was still active and needed to be replaced). Everything else was in pretty good shape. The seller had already informed us that the roof was getting a full replacement before we even made the offer, so there was no need to even bring it up.
