Agent, lead generation2.

They make their money charging realtors for leads. 

And like Jon had mentioned, you may be able to get direct access to CRMLS without having to be part of an association.

I've just started reading "The Book on Rental Property Investing" by Brandon Turner, so I'm excited to get learning on that.Question for the community, how did you all start your education journey that lead to your first investments (books, youtube, bigger pockets, etc)?

Which leads me to...3.

Algebra and Geometry books on how they relate to REI.Proper knowledge on ho to analyze marketsThe importance of learning as many different strategies as you can, and then knowledge about those strategies, how, when and where to apply them, and the math behind them.Learning what a REI Plan is, and the difference between a Plan, Financial Goals, and the steps that lead you from where you are to your financial goals.The most important knowledge, is how all of this goes together.Now I've already done all of this, and more, but these are some of the most important things that are lacking out there.

Currently have 4 rental properties and a good amount of equity which could allow me to break into larger real estate (multifamily, self storage, luxury str).

If there is something that needs a licensed tradesman, he has plenty of connections and it leads to reduced rates.  

However, there is a reduced sales tax due on the rental of commercial office, warehouse, self-storage, vacation rentals, etc.

I will send you information directly, not to sound like propaganda.
