As a broker doing all investment real estate and having to deal with other realtors on a daily biases I can tell you that most do not understand it at all.

If you want Daily or Monthly Cash Flow you need to learn how to trade Futures.

I have to check the city site daily to know what is happening with my permit.

Greenville SC Real Estate Investors Group is a really good group on FB that meets up, posts deals daily, and has interactions. 

In my lease, they become holdover tenants and are charged 4x the monthly rent, prorated on a daily basis.

Deep dives with Financial Independence (the Mad Fientist), Journey to Launch (Souffrant), Money for the Rest of Us (Stein), Optimal Daily Finance, Stacking Benjamins, Big Picture Retirement, and Radical Personal Finance (Sheets) all have great information. 

Hopefully one day I'll say it was the best decision I ever made for my career, personal daily life etc.

They are often Agents who like to try and work with investors but unless you have investments and work with them daily its difficult to understand how it all works. 

Stocks go up and down daily but real estate, read the trends.

@Taylor DaschI understand the rule, but I read and hear on the daily that people will finish a property, then pull the money out of that property to pay off the previous loans,, then do a heloc on the property they just finished, just to buy another one and repeat.
