I have had my share of problems with realtors, but I have to agree with the crowd here. You need to put your ideas in writing in the form of an offer. I have never written an offer wherein I couldn't back out were it necessary. I have never had a problem getting my earnest money back. In fact, in most cases the check was never even deposited in the very early stages of negotiations. Realtors have to kiss a lot of frogs before they meet a real buyer. Time is money; don't waste yours or theirs ;-)
