Planning to install cameras in the lobby and other entrances, Not sure this will fix the issue but trying to see how other landlords are handling this kind of problem.

I dont get many Airbnb bookings so that is less of a concern for me.I have a lockbox that has never failed, never needed batteries so I haven't been motivated to fix what isn't broke.I do have wifi thermostats and hot water heater as well as hard wired security cameras (no batteries to replace)

I wanted to ease her mind by getting security cameras for the outside. 

Installed ring security cameras years ago.

Once they cleared it they ran a camera up since they said there was some mud and also an earthworm in the main line.

Aloha,Consider a decent remote access camera system to identify the rats and provide evidence.

but I’d rather buy ghetto properties now put up cameras deal with some BS and then sell for 30X in ten years.

What you can expect is they will start putting ostensibly affected “first responders” in front of the camera just like they did last time.

Well I have cameras I had the activity recorded.
