Hifind domains that they flip
Man, if you're looking to flip like the pros, you gotta stay on top of GoDaddy, NameJet, and DropCatch auctions first. That's where most action is. Second, tools like ExpiredDomains.net help catch good deals. Don't forget about private deals! Sometimes real gems hide there.
PS. Once you build a reputation, people will come to you with offers. ; ]
You will go broke very quickly paying dropcatch prices for the majority of dross they list. You're better off looking at already established domains with known traffic stats.
