Feel free to add me on here.

I have been trying to learn about real estate on my free time right now but I just feel like that is not enough.

Start networking or pulling lists of owners that own properties free and clear.

I would guess that the number of properties that are owned free and clear that don't need the money immediately may even shrink that pool even further.What if your seller had the ability to sell his/her note for cash at a discount after approx 6 months? 

Do what is average in that neighberhood.Are you going to go do "door knocking" or "driving for dollars" to get leads and find motivated sellers.  

Long term goal is to have enough rental properties, single and multi family, to have enough passive income to be my own boss and financially free!

In addition to the podcast, blogs, and forums, I found the BP books to be super helpful and easy to digest: http://biggerpockets.com/books and there's also a free intro video course that has a lot of the same material as the Book on Rental Property Investing: https://www.biggerpockets.com/courses/a-beginners-introduction-to-real-estate-investing

Feel free to shoot me a message and we can set up a time to discuss options.

You are in the right place- there are plenty of free or low cost resources on this site that can help you determine the kind of real estate investing you want to do, the area you want to be in, etc. 

I heard this is a good book to learn step by step  O ya I heard it was free!
