Apart from all that, we ourselves are in the business of real estate , the hardest thing was ourselves to obtain the attitude of an investor ourselves, it took years , it is an attitude. Number crunchers have a hard time “ starting” and it is the start that is the hardest.
If you are going to read books, my advice is to focus on the attitude books. Just do it. The technical books are great but they can hold you back. After all do you need to know all about a car to drive one or do you get in , have a destination in mind , turn on the key and go.
