Okay, I'm getting grumpy! I'm tired and have not had a day off in a while. With that being said, let me get this off my chest!
The purpose of the home inspection is NOT to renegotiate the terms of the sale. If you put in a purchase offer on a house with a tarp over the garage roof, don't expect $5000 concession because the inspector says the garage is a piece of crap.
The purpose of the home inspection is to discover defects that were not obvious at the time of purchase. There is no such thing as a perfect house. The inspector will let you know what is imperfect about it and you decide if you can live with that imperfection. Sometimes the seller will fix the imperfection. Sometimes the seller will offer a credit so the buyer can fix the imperfection. But the inspection is not intended to renegotiate the terms of the purchase.
There! I feel better! Now, hopefully I can go back to my normal smiling self.
