Property Manager exploring alternate lines of work . What types of jobs should I consider in the future?

I have been a Property Manager for 20 years with no formal education. I am wondering what types of jobs will share similar skills that I should consider? I cannot be an on-site Manager since I am a homeowner now. I've been considering getting a degree but which one would be most desired to further my current expertise? Are there online colleges you'd recommend?
I primarily work in an office setting but often go outside the office to inspect homes, show homes and check repairs. I prefer that in/out combo so as to not be stuck in an office/cubicle all day although I may not have that choice priviledge.

What about real estate? Get your license and you are already ahead of the game with your backround!
Good Luck!
