@Rick Albert is right on and gives good advice.I'm actually wholesaling a property this week, but this just happens because I am in the game doing flips, developments, and rentals. i would never try to make a business out of it.

Do you mainly rely on driving for dollars, online platforms, or networking with other investors? 

Don't quite understand what you mean.Wholesaling has nothing to do with where you grew up.Wholesaling (as well as any other business) is about lead generation.I didn't grow up in NYC, and if I were to wholesale there I would dominate that market with my ability to rank websites #1, dominate online presence, credibility, and competence strategies I can apply to my online image.I think this is why so many people are "afraid" of wholesaling.Break wholesaling down into its most basic elements.
