What REI jobs are there?

[Jeremy Blevins]

Hey BP, 

I was listening to a recent BP podcast (episode 394) where they interviewed Elliot and Chrissy Smith. During the interview they talked about how its a good idea to have another job or business aside from your REI business but, that's related to REI. I guess I always thought that once I had a certain amount of rentals, that would essentially be the job. While this is certainly achievable and you could focus solely your rental portfolio, I started thinking about what jobs there were in the real estate space, aside from managing your rentals. I'm curious, what jobs do you do, or know of, that someone could do in real estate?
