Home inspections and the tax credit

I have a seller who just recently had an offer and accepted on April 30th at 11:59 PM.  Yes, the buyer did cut it close on the tax credit.  Now I am hearing from my seller that if the inspector finds anything wrong with the home that they are not going to fix it.  He states that he if they do not like it, then I guess they will just miss out on the $8,000 credit.  I said this maybe true, but you will still need to disclose this on the disclosure statement.  I also reminded him that he is close to clsoing on his new construction home and that it is a risk that they would be taking by not cooperating to work any fixes that the buyer may ask for.
