Tenant is a hostile/confrontational individual."

You are just mad because I confronted you over your illiteracy and personal bias.

And has been very confrontational and demanding.

I don't disagree that you should at least start the eviction process, but I'd knock on the door and confront her, in a professional way, obviously.

@Claudio Romero, do what everyone else is doing nowadays:  When he confronts you again pull out your phone and start recording him, then name and shame online. 

Confront the situation? 

The thought had entered my mind but was unsure how the general sentiment was for investors and how they  confront an eviction scenario right out the gates.

Case in point Holiday falls on the first of the month which is a Friday, and their company pays payroll the day after a Holiday which is Monday. expecting payment Thursday would be a bad idea, because that means they pay their rent a near week before payday.I would deduct from their security deposit for fines, tenants are living in a high value asset, they can destroy property confrontation should be avoided.You should take responsibility for pest control its your asset you are protecting.Steep fine for painting, you might as well say eviction, you will never collect that money.Don't restrict your payment methods. 

If they don't comply you are better off evicting them.I would not confront them in person without police present.

Confrontation with the other investor may not be the best use of your time.
