Not only do I get them to sign a buyer agent contract, I charge them extra. If they agree, I know we will close and not just spend time running in circles. I am not outrightly looking for Buyers, so when they appear, they must play by the rules, otherwise - Next! Too much time lost servicing my Sellers, to waste time on Buyers who are not very very serious. Sometimes it takes a couple of meetings to get the signature, but like some others posted, the Buyer needs to go work with other agents to find out what they're missing. Then they come back and sign, gladly, on the dotted line because they know that "I" am serious, too.

(too many questions get asked? - agents get frustrated, too)
