@Robert Lum  you bet you can troll around a site like BP read their books listen to the pod cast of those that are successful and talk about their business's.. its inspiring and motivational.but if you really want to learn the nuts and bolts you need to get in the game.the best and least expensive way to do that is to simply take a pre license course in your state.. learn the laws ( the real laws not the BS that is talk about on line).. terminology etc. then go to work with a brokerage in the aspect of Real estate that interest  you.. there you will get REAL training by those that are successful you get on a team.. you get paid as you learn.

One of the reasons why I’m bullish on real estate investing is because I am more afraid of the “what if I didn’t invest” rather than the “what if it goes wrong.”Yes, I could fail and lose everything I started with, but I’d still be farther along than if I never started at all.I’d have the knowledge, skills, and lessons that only come from taking action.Every misstep is a step forward when you’re learning and adapting.The real risk isn’t failure, it’s standing still and letting fear hold you back.Take action!!!
