Surely it is the value to the purchaser that has increased, as she sees it, and thus motivated her to raise her asking price and re-negociate a deal not yet agreed to or concluded, but entered into on assumptions — by both sides — that didn't turn out to be true.
Sorta like the poor farmer asking better than a dust-bowl price from the guy, when she finds out he's an oil company geologist whose test proves there's oil under the land, and she thanks the Good Lord the signature lines are still blank.
Maybe he should appeal to her patriotism. Or promise to recognize her as First Bimbo.
They may neither of them be nice folks but …. He's still the shyster in the deal.
