Termites home help please

[Claudia Acanda]

Hi quick question, went under contract for a property. They did inspection but they could not get into the attic due to the ac unit blocking it thus they couldn’t check there or check for termites… he recommended to do a hole on the attic to inspect. Then we followed up with a termite inspector he said the house was ok bc it made out concrete and the rest some metal part? (Idk) but again he couldn’t access the attic he strongly suggested to do a hole. We brought this up to the agents attention and quickly dismiss it saying the sellers won’t accept to create a hole on the attic, that the house is buy as it is (this was never in the terms to begin with) We offered to pay for the handy man to close the hole afterwards too & nothing. 
mind you, it’s not a cheap home, it’s not for closure home, seems to be in decent conditions. How can I go forward about this situation?
