You have been getting some really good advice, the best of which is joining a local REIA group. You can be a fly on the wall at these groups and pay attention and learn the hard stuff (learn from other's mistakes) and the rest, contracts and paperwork can be learned from books or find a good closing attorney in your REIA group who can help you not make big mistakes.
Be conservative at first, get your feet wet. Or find an older person who has been doing this a long time to see if they will let you hang out with them to learn what they do. I had 2 uncles who would have done that for me in a heart beet but I was too late joining the game (they passed).
Nothing beets a good REIA club! Nothing! Our club (Memphis Investirs Group) not only has monthly educational meetings which include a theme for the night but also 2-3 break out "early-bird" classes on specific topics such as "getting Started," "insurance for investment properties," "buying multi Units," "tax sales," and hundreds more. We also have a once per month "meet & eat" night with a more in depth look at a single topic. Sometimes it's on things like "running your RE business from an iPad...only" and a bunch of other topics. Also we have a casual Friday Dutch treat lunch at a local restaurant. This is a time when the experienced folks get together and are available to answer Your questions.
GO TO EVERY MEETING AND EVERY LEARNING OPPORTUNITY. LISTEN TO EVERY PODCAST. CHECK OUT BOOKS AND BOOKS-ON-CD FROM YOUR LIBRARY. LISTEN TO EVERY PODCAST, TAKE NOTES AND YOUR QUESTIONS WILL EVOLVE INTO SPECIFICS RATHER THAN SUCH A BROAD "HOW TO".
You need to network with these people. Study hard, read everything you can get your hands on. Find someone in your area and work with them, pick their brains. If they don't want to help, find someone else. I tried to get my RE Agent (who helped me sell my personal home) to help me learn and she was literally clueless about the investment game. Like Doctors, RE Agents practice in certain areas, many are clueless about the investment side, most are just retail. You will find the people to learn from in an investment club.
