By “Quiet title” he’s referring to a quiet title action, which is essentially a lawsuit brought to remove a cloud on the title and clarify ownership of the property and establish clean title.I’m not sure why the OP did a quiet title, but in my state (California) they’re sometimes done with tax deed sales so you can obtain marketable title to re-sell the property. 

And i know Joe hosts one in South Orange county as well, so whichever one you're closer to or would prefer would love to have you.

A good place to look are tax auctions that most city’s host annually.

Vegas is the global barometer of that, if anyone is incentivized to get conferences going, it is the city that often hosts 50000 business people at a time across all their hotels.

This question is akin to saying "tell me good things" so I'm going to try to give you the single best high-arching piece of advice that I know, then direct you to some further resource:Do the "cloud work" of finding your why before you start.
