Personally, depending on your situation, I would start with stuff that is free. Education (on this site) is priceless, and free. Also, try to find some players in your market and see if you can follow them around, answer phones, or do some work for them for free. Education is everything in this business, and it will help you to avoid making very expensive mistakes. My two cents. I am choosing to save up some capital until I can afford to handle mistakes, before I jump into a 6 figure decision. Best of luck!
@Daniel White to add to suggestions of others, start networking in-person and ask to shadow others while offering to help in some way. Experience with handyman work, or painting, offer to do it.
Also, put that $500 in an account that is not to be touched except for real estate.
Great advice here. Getting a job in the real estate industry would be a great way to get your feet wet in real estate and get paid. You could be a property manager, handyman, leasing agent, real estate agent. Or find a way to add value to a local real estate investor, shadow them, and get paid a small base salary to cover your expenses.
