but an inspection can tell you if there was past water damage that was covered up or mold or anything like that. Had 2 friends back out of purchases lately because of things that turned up in an inspection. Some lenders will also require an inspection
if your looking at new construction thats a whole other story. I actually opted out of mine but it was a brand new house that also came with a 1 year warranty.
Regarding the inspection, I put my full inspection up in my house thread in the NWS area, on page 3, near the bottom: https://hondaswap.com/threads/house.525952/page-3
You can check that out to get a feeling for what you get. It cost $595.
