Just starting found 3 fsbo's, what do I say to the seller and what are the best strategies to use?

[Lonnie Zinnamon]

Wanted to know what do I say to the seller when I call them? Should I look up comps in the area before I approach the sellers?   I've read many of the fsbo posts, but I haven't found a post that solves my problem. I want to get a grasp on wholesaling, is finding fsbo's a good way to find deals until I can build up cash for direct mailing and buying bandit signs. Need some feedback, so I can move forward with taking action. Thanks for your help.
