I joined after reading 5-6 of the BP authored books and I've loved growing my understanding of the world of real estate investing.I made my first investment this summer and my family is partnering to make a few investments in the next year.

Buy a few books, start simple, do your own property managing.

Both great books.

Quote from @Dan Lucchesi: Quote from @John Underwood: Lower price and advertise in more placed.I even get an occasional booking from a perpetual free Craig's List ad. 

As a newbie, I need someone to guide me from the beginning to try to avoid mistakes and hopefully be very successful.

See if your state has something like that on the books.
