Who knows, you may even find a  partner or someone hire into a small start up while you start a formal education?   

Should I hire a lawyer?

If he doesn't want to leave, hire your other tenants to spy on him.

Have you hired anyone as of yet?

I understand I’ll have to hire a property Manager, I just don’t understand how security funds are handled Incase of emergency and immediate attention in the scenario where I may or may not be able to reach right away .

We simply do too much business for me to handle myself, so we had to hire additional agents.

Hire a excellent agent who understand the local market. 

We ending up hiring our office lady, leasing agent, cleaning people, lawn care, superintendent or handy man, and outsourcing all those jobs that we couldn't do remotely. 

So if you are hiring out the entire rebuild, you would probably be closer to $180-$200/sq. ft.

When you get larger to reach your goal eventually you are going to have to either take over full time (so much for retirement), or hire someone (PM).
