If you allow a pet, go in the unit or home 1 week later and check on the housekeeping and the animal's conditions, if the is an issue grow a pair and speak up and correct it, leave with the understanding that you'll be checking again or make another excuse like, I'm going to need to get in here to check the HVAC soon, I can call you a few minutes before I come as I'll just be swinging by when I can.

They will be a difficult pair until they're gone.

I have one Labradoodle, and she has already destroyed several pairs of shoes and books, and started a fire.

I ended up getting a pair of the Ring Video Doorbell 3 Pros, both are connected to my unit's WiFi currently.

The thing i cant do without is my impact driver  :) also a basic pair of pliers and a multi head screwdriver  This is a great list so thanks for posting it!

You can find cheap ones on CL for like $300 for a pair, I'd recommend installing that.   

Assuming they work, they will sell fast and you can easily get $150-200 for the pair. 

A pair of panties got wrapped in the washer motor and broke it due to over loading. 

If it were me, I would proceed with some gradual increases, and maybe pair that with some niceties - i.e. address some maintenance the previous landlord was deferring, a fresh repaint of a room or two, etc.
