I appreciate the boldness of confrontation in constructive mannerism.

Sometimes you have to confront these shady characters in person, whether at their place of business or home.

I confronted the tenant and she was insulted and said she did not have a dog living with. 

You might fear a confrontation.

And really, it seems like the best it does for a landlord is help to avoid confrontations with tenants who were too cheap to pay for renter's insurance. 

I don't know if they realized repairing torn screens would be cheaper than replacing missing screens.Their new landlord has informed me that they're behind rent on her house and have made changes that she's worried about but hasn't confronted them on.During the move-out inspection of the next tenant, several things were pointed out as "that's the way it was when we moved in", such as a broken countertop corner, broken cabinet hinges, holes in walls behind doors and conveniently placed posters that were left from tenant to tenant, and poorly repaired damaged window sashes.What I've learned from this experience:I now have an inspection form that I follow so I can be more thorough. 

It started with loud noise and has escalated into throwing eggs at cars, bottle onto their porch, and direct confrontation.

Post a notice on her door that you will be entering the property and confront her and ask her what's going on.  

I just want to make quick work of it - not sure if there will be a confrontation...I just want to be in and out and not have to worry about botching the locks in the process.

It's definitely easier to have someone leave for non confrontational reasons in a month to month (selling, renovating, etc) but from an eviction standpoint there are a lot of variables.
