I think you did the right thing. Now you have a bargaining chip and better knowledge of what you are getting into. We had a friend do our home inspection and he didn’t even crawl under the house. He knew how much my wife wanted the house so I don’t think he really wanted to find any major issues like deteriorating cast iron pipe or recently fixed foundation (I think everyone knows what that means). All in all though I will admit that we would have bought our house anyway because it was not house A versus house B for us @ the time but more of house or no house @ the time. I think all inspectors find lots of issues but it is the big ones that you really want to know about. A personal peeve of mine is that the big ones are probably known to the seller/realtor and I’ve yet to hear them pointed out by them.
