The idea is that under these conditions, I would not personally benefit which could be viewed as acceptable non-rule breaking actions. 

I found a person who had all ready been transferred to a new location with his job and had been unable to sell their home.

What I've seen from watching videos is that the tax court will not believe someone is working 4160 hours. 

Personally, I hate cash for keys and I can hardly think of a reason that I would do it - BUT I am in a state where it's pretty simple to get non-paying bums gone.

It really depends on your goals in the long term, personal resources and what you need.

Even the units I own personally (under and LLC) the tenants do not know that I am the owner.

Finding turnkey deals that cashflow well is EXTREMELY difficult especially if you are looking for ones that you like personally.

BTW, you get what you pay for - the cheaper ones are robotic/scripted while the good ones (more expensive) have presence, personality and situational awareness -  which helps with appointment setting. 

I'm looking to do a personal project of mine where i'll be building my own personal residence and decided to do it with just straight cash, and the idea was to cash-out refinance the property after it's completed.

It sounds like you want a personal loan from a bank.
