If you had one to choose? How can I supplement my REI?

[Jonathan Beemer]

Hi BP! If you had one to choose what would you be to increase your ability to be the best RE investor? 1. Realtor 2. Contractor 3. Both 4. None- normal real estate investor ?? I am thinking about learning something on the side once I am out of the army to help with my investment strategies. Not looking for anything too long. Just something that I can work in until I have enough passive income to go full time. I am young, I have time, and I have the ability to do anything. Any other options??
