The reason I avoid your emotionally unstable phone calls is to purposely document via text and email your erratic and unstable behavior.

The minimum threshold for ethical behavior is obeying the law.

I don't reward bad behavior with financial windfalls.

Variables of importance are max delinquency last 12/24 months, LTV, CB score, behavior score, employment history, income, etc.  

I posted an eviction notice as a lease violation, as we do not condone violent and illegal behavior in our properties.

Any lender looking at such behavior would question your ability to stick it out with a project, and probably be reluctant to loan you money for your real estate.

That s/he grossly mislead you or lied to you about a fact or facts to induce you into closing.As others have also stated, ARV is a subjective opinion and as such it may be impossible to prove a fraudulent behavior. 

I'm confused about his strange behavior, but I'm also glad to let him go and I hope his buyers find a way to let him go.

But my wife read it, too (she is very much not a business oriented person), and said to me when I raised concerns, "But didn't it [RD, PD] make you think and start changing your behavior...?"

These days, more and more members of the general population have goon from good to bad (example of strategic defaults comes to mind here).So, how would you be able to guarantee that behavior will always remain as good as the referrer experienced?
