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.

How do you let the applicant know that despite paying for the credit and background check them may not be choosen without making it seem like it is a personal thing?

He does my personal taxes and everything for my 10 apartment complexes, partnership returns etc.  

Personal loan

Personally I am not handy so going through a GC would be best.

Unemployment will tick up heavily end of Q1 into Q2 and that's when the realization of this consumer debt: personal savings disaster that's been brewing will show up.
