An investor can create a deal out of thin air.  

Can I start the company and hire an agent to sign the leases and list the properties?

If you have ever been a technology hiring manager (and many other hiring managers as well) in the last couple of decades, you have probably experienced the incoming 'stack' of resumes when a position is posted.

By the looks of it i would say your Dad is right, it looks like the concrete has deteriorated due to water. you do not need a foundation co. just hire a mason to cement it back up inside, but first take care of the cause on the outside, get that leader pipe to drain away from the house by either extending the pipe above ground or dig a shallow trench and run a pipe under ground away from the house. also make sure the soil around the house is pitched away so that water moves away from the house.

Would it be worth it to hire an attorney or should I just wait for the November court date.  

I would strongly suggest you hire an attorney that specializes in evictions, as I once learned the hard way.

I am in southflorida area 3 is it better to hire appraisal officer or inspector??

In time you will develop a feel for costs but to start out you should probably not consider anything too complex and be careful whom you hire to do the work.

To determine the exact standards that you need to conform with, you will need to fully investigate your individual state statutes and regulations and or hire the appropriate licensed contractors and licensed property managers.   

Eviction costs are quadruple the cost as I am required to hire an attorney at 1200+ vs doing it myself for 300 bucks.250 in business fees to the stateEquity loans/refi's/anything of the like falls under "commercial" and is EXTREMELY expensive.
