Breaking Contract

I haven't seen your contract, and I don't know whether it contains any contingencies besides your financing clause, or for that matter how that's worded. Someone once told me that a really good lawyer can almost always find something that justifies voiding a contract. I doubt that, but if you really want to try, take the matter to the best real estate attorney you can find. He or she can tell you whether you have any grounds for getting out of the deal, and what you stand to lose.
