Pre-investing options?

[Justin Foster]

What are the jobs that can be done prior to investing that will still give either useful skills or directly relate to real estate? And what are the education requirements of each?

So far I have found:

Real estate agent
- License required

Real estate appraisal
- Associate degree

Property manager
- Bachelor degree

Development/Construction
- (Couldn't find)

What are some more options? Preferably ones that don't require a lot of time to get started with.
