Don't do it.. Interest rates going to go higher due to the failed treasury auctions. IF the 30 year treasury auction is bad tomorrow, I can guarantee you there will be jump in rates and the other the other "potential" buyer who released the contingency will be SOL. Keep your loan and inspection contingencies in place. If the other "buyer" pulled their contingency, its pretty surprising why they would would have done it while still letting the seller take other offers.
