Essential Real Estate/Investing Books

[Jon McCarron]

Newbie Investor from the North Shore of Massachusetts. I am interested in buying and holding multifamily's for cash-flow (but not ruling any strategy out). I am interested in interacting with other like minded people, whether they are seasoned investors or beginners, like myself.

Moving on to my first question for the community.

Currently, I commute to a job in Boston by train. I have about an 1 1/2 hours to read on this commute, daily. I want to know from biggerpockets community: 

What are some of your essential real estate/ investing books? They can be books related to a particular strategy, general wealth building, inspiration, motivation, etc. Anything that has helped you get to your own real estate goals.  

Thank you! Glad to be apart of this community!
