The cost to repair the system was high, so we decided to move to a flat monthly fee for utilities.

Some PMs charge a full month's rent, others charge a flat fee. 

How to screen the tenant.  

Quote from @Roger Garner: I don't have any recommendations, but I can provide you a guide for screening and selecting a quality PM.

Patio screen door has many holes - replaced with new screen.10.

If the new tenant passes your screening criteria, rent to her. 

A couple of months ago, a screen popped up forcing me to pay a fee in order to gain access to my account.

My strength admittedly is on the administrative tasks.For those who are opposite of me, who struggle with the administrative side, would you consider a B2B relationship with a service that takes all of the tasks off of your hands, and if so what would you be willing to pay (% or flat fee).To be clear, what would be offered would be:- Listing on 15+ channels including Marriott Homes and Villas, Abnb, VRBO/, Booking.com, Zillow, coming soon Amex Travel and Hyatt, Jetblue and Allegiant Airlines, and more.- Pricing software w/ live revenue manager- Smart Lock software- 24/7 Guest Communication via platform, voice, text, email.- 24/7 Communication with owner or PM staff for maintenance or cleaning issues. 

I'm not saying you actually violated any laws or committed any human rights violations, but this is exactly why it's vital to have an objective, documented screening process and publish your criteria on every advertisement for the property that you put out there.
