You need to have consistent inventory and be a serious player to pull #1 off, assuming you are in a competitive market.

I think is about relationships, after you reach out to all the wholesalers in your area in all the diverse ways possible and exposing yourself as an end-buyer on platforms like Facebook, you then start to vet out all these wholesalers and with time you'll see who the real players are and who the daisy-chainers are

Overstating the profitability of this endeavor by grossly understating the competitive nature of the bidding, the sophistication of some of the players as to research capabilities, etc.5.
