Not to scare you away from buying, but builders can always hide things. I bought a rowhouse earlier this year, and the inspector didn't find anything major. Well, a few months in, the floorboards in the kitchen started to buckle. After some investigation, we found out that the flippers had built an addition on the back end of the house, and put the framing of the floor directly in contact with wet ground. All of the wood is rotting. It's a code violation. Based on the documentation I got from the city, it appears to me that the builders were able to close up the floor without letting the housing inspector see what they'd done. Of course, the construction was approved. There are some things an inspector just can't see.
