Any courses or Mentors worth following?

[Rodney Maspoch]

I'm a newbie who's tried sending out Neutral Letters and looked into Tax Deed/Lien sales but has not had luck in getting through the entire process. I'm looking to see if there is someone working in South Carolina that I can help and work for to learn the process and the ropes before making a costly mistake. Too many gurus and courses out there, I've learned a lot from Seth Williams ( Retipster ), learned from Dustin Hahn ( Tax Lien Certificate School ) but all through their free resources, and then giving it a try myself. I found that Deeds in my area were outside of my budget, often getting bid up to close to market value or at least higher 5 figures. So I've started looking at Liens but I've always loved the idea of REI whether it be land, rentals, AirBNB, or flipping properties, I'm open to learning so I can focus on one and go from there.

I'm looking to see if A. anyone has a good suggestion of a course or a person that they know provides the best knowledge and bang for the buck to get actually started vs. regurgitated stuff that is already provided free on BP or Retipsters, etc. And B.  TIA
