I think anything that prospects may hold to that has your name/face/number has potential...pens, keychains, sports schedule magnets, recipe cards, newsletters with good content, etc.

I agree with Bee. I have handed out my keyrings whenever I even show a house and I am seeing them all over town now, in people's hands. Cool.

My favorite handout is my Stressometer business cards. They feel like a credit card and have your info on one side and a stress meter on the other. People press their thumb on the stress meter for a few seconds and it changes color to indicate their amount of stress. It is not only a lot of fun, but helps to relieve the anxiety with buyers and sellers who are in negotiations by adding a little humor to the atmosphere.

They are $.45 to $.50 each depending on where you buy them and they never run out of ink! Here is what they look like:

Gene, those sound like Mood Rings of old!  Great, no matter . . . :)

I loved mood rings...since most of my clients are boomers it seems, I think they would love them, too!

I use pens and magnets. I've been getting more response lately with the magnets. I started mailing them with all my mail outs.
