I have stopped answering phone calls and resorted only to written communication (for my records) but have noticed a pattern of very emotional and aggressive behavior from this tenant (as well as extremely unreasonable expectations about what the timeline is to have something fixed).

Yep, pretty typical behavior for her. 

That behavior is typically what prompts the beginning to the end.

I'd check with the current landlord to see if there are behavior /rule following issues. 

Have a lawyer send a letter that if the behavior does not stop, you will be issuing a notice to quit.

Don't reward their bad behavior by paying them!

I’ve gotten pretty good at predicting behavior, so it’s easier to select good tenants.

., "pay" for your conscience - self manage, or find a property management company that wants to manage the unit based on your idea of ethical behavior rather than market behavior. 

I have his behavior on a record.

If she lies about it then I definitely would pass on her, but if she admits her past foolish ways and has all appearance of current responsible behaviors and succeeding in life then what more do you want ?
