thanks MRO - it's all there in black and white in the contract but the vendor is stating that they want the inclusive price and then we pay GST on top of that which amounts to another $50K and that's just not happening. It is a valid contract which the vendor's solicitors are arguing that it isn't because the agent didn't 'have written authority' to sign it. And they won't back down on this argument. I think we walk away. They will have to re-advertise, re-engage another agent (I know they won't use the same one) and re-auction. You never know - we may just get it again at an even lesser price.
