If that is your plan then I wouldn't be surprised if a lender or servicer eventually caught wind of it and realized that you had bought 6 or 7 primary residences over the past 3 or 4 years and considered that the same as lying upfront. 

., the guy is very angry at his current circumstances and I would give him some deposit back if I believed he would move out on his own, but I from the lies, and his statements I think he is going to stay as long as he can.

If the seller lies about paying the fines, what else are they hiding?

I would by lying if I said I wasn't..but financial freedom for what?

If you still are thinking about it, do a complete background check, verify employer, past 2 landlords (the last one might lie to get rid of them) , pull their court cases in your local jurisdiction, look at the interior of their car, take a photo of their ID, etc...

I cannot lie to potential buyer and tell him that I spoke with him either via emails or phone calls if I didn't.""

My main confusion lies in how to set it up for flipping?  

I don’t know how much money is involved but as a “not a lawyer” I would assume all management fees should be refunded to the clients if they were lied to (defrauded).

They also often lie to sellers about their real intent (FRAUD).

All the info you get off cozy is much more valuable that anything they write down on the paper application, plus tenant tend to only tell you the good things and lie about the bad.
