Which gives me much more control of the money/asset management than just leaving it in the market for alot more years.

- Controlling costs for payroll processing, unemployment charges, workman's comp and liability insurance- Coordinating ServiceTech & tenant schedules for appointments--- There are several industry vendors that focus on just this!

Even the subpar situations we have no control over.

Mostly NYC real estate companies uses Yardi Voyager and not the Yardi Breeze that most people here in BP uses.Even if you get a job that uses Yardi, you will have limited access on what you can and cannot do just because the role you are in unless you are a Controller/CFO.

Like you I also have the RE license to keep some of the commissions and better control. 

He scheduled maintenance and did quality control on cleans. 

There is a provision in all my contracts that permit me to assign the contract to a newly-formed entity that I control.
