Six months ago I would have never considered a career in finance, but that's what happens when you find your passion.

Josh solicited videos on this topic about a year and a half ago. http://www.biggerpockets.com/renewsblog/2010/12/05/first-real-estate-investment-deals-video/

I have no actually close friends that do this and I can tell I'm missing having friends with similar passions as me.

Find out what you are passionate about, become a world class expert at it, and outwork your competition to get the life you want.Don't expect extraordinary results from average motivation.

I am now building a "Living in (city)" Youtube channel. 1 video/week (free), and I have been at it for 1.5 months, I have generated 1 call, from a renter.

Looking for recommendations of a simple book or straight forward (short) video that explains the benefits of real estate investing to a teenager.

I have learned a lot by reading from various sources (including BiggerPockets) and from watching / listening to hours and hours of YouTube videos. 

After listening to BP podcasts, reading books, and watching videos for years, I am finally ready to take my first actionable steps. 

Rent to own or lease options was recently brought to my attention after watching a video by Kris Krohn on YouTube.

I would read as many books as you can on deals, watch youtube videos from investors (who arent trying to sell you 40,000 coaching programs), and listen to podcasts.If you want to get into multifamily but have not invested in RE before i would recommend starting off with a duplex to quad and learning the basics of the game and see all the expenses, headaches and challenges that come with running a property on your own.
