Hi Michael,
I agree with most everything that has been said.
1- I would say that you need to start with the end in mind like Dan says, know you goals and understand why you want to invest in real estate.
2- Always keep in mind the thought of how you can help others in this business. You will get ahead by helping others reach their goals.
3- Learn, learn, learn… because at times you will get advice that may not be correct. For instance, you do not need a pocket full of money to start this business. By that I mean you can buy a house with a contract only, find an end buyer, and collect the difference at closing without ever taking title or putting up any money! Their are many ways to skin a cat.
4- You are entering into a very different market today than many have ever seen. Your exist strategy will be one of the most important tools in your bag so that you don't get stuck holding the bag!
Best of luck and hope I can help some way.
