Two wholesaling questions

[Micahel Lorent]

I have two major wholesaling questions that are troubling me:

Firstly, when you wholesale, does it matter if the seller owns his home free and clear or does it make a difference if he has a mortgage on it?

Secondly, how exactly do you go about finding and analyzing deals? How do I identify a "good" deal?

I've heard alot of suggestions about using agents to pull comps; if I did this, what exactly would I ask for?

Thanks for your answers! I think I'm getting my head wrapped around the wholesale concept and hope to begin soon. I want to first, however, find a good investor-friendly title company and get an agent that can help me when I need; this should be my "team" for now, and then find buyers (lots of great threads on doing that! :D ). The last bit of the puzzle is just: "What is a good deal"?
