In some areas, the *seller*, not the buyer, is responsible for
getting the home inspection done. That seems to be the case
here.

In which case, the seller is in default. Oops. The buyer can
(a) demand refund of the earnest money and walk away, or (b)
negotiate a new contract with a new (lower) price, or (c) sue
(or merely threaten to sue) to force the sale per the current
contract.

Hope this helps,
