Mistake # 2 tolerating any delay.  

Given what she came from, putting up with him probably isn't a terrible price to pay, and many East Asian-born men treat women so terribly that even he might be tolerable.

Illegals, bad credit, evictions, criminals, S8, what is your standard of risk tolerance.

We also tolerated literally hundreds of emails and voicemails, berating us and our team members...usually written in the middle of the night. 

I no longer tolerate late rent, I thoroughly screen my tenants (background, criminal, credit) and I make sure to keep organized and detailed records for all of my properties should I have to go to court.
