Both of them are extremely knowledgeable, the course content is thorough, and most of all affordable for a beginner. 

Plus most retail buyers and sellers like having an expert on their team to ask questions and make sure they aren't making beginner mistakes on what is often the biggest financial transaction of their lives. 

I think it depends on the strategy right , I am still a beginner and wanted something more turnkey rather than BRRRR.How would you think of something form that perspective ?

This is what can go wrong when you have beginners wholesaling who have no training in real estate, no experienced managing broker to go to for advice, no license, no E&O insurance, no knowledge of how to avoid scams, no regulatory body to answer to, no relationships with other quality people in the industry like title companies, lenders, contractors that they can refer to help people, etc. 

Like "renting to section 8 tenants is actually really easy", "your agent is not on your team just connect with people like me doing hundreds of deals every day and use my team instead", that hood properties will have "15-25% net caps" for beginner out of state investors when in reality they will definitely lose money every month due to the rent not being enough $ to maintain a rental property, never mind all the tenant issues involved with this property class or the difficulty of managing them remotely... but he's done thousands of them just this week while sitting on the beach in Florida... 

Every expert started as a beginner—take the risk and start your journey today!

Is there a beginners guide I can reference?

For a beginner looking for long-term real estate investment growth, here are a few great options:Buy-and-Hold Rentals: Purchase a property to rent out, which builds equity and generates passive income over time.

For a beginner, it will be wise to start with a property that requires less hands-on management, like a turnkey property or one needing only minor repairs.

I also feel like it is pretty beginner friendly in the sense that no cashflow or even slightly negative cashflow still provides opportunity through equity gain.
