I don't think the OP fully understands the reasoning behind what was a case of first impression. He should also read the Supreme Court case the court relied on. It is a far more subtle and complex issue than the OP seems to let on. Also, I'm uncertain how "damages" are being measured by the OP. The inspection did not guarantee the entire house was correctly built. To me, it seems the case belongs against the seller who did not disclose the water problem.
