@Alyssa Czopor I use the following to self manage remotely: keyless entry, wifi thermostat, ring flood camera, iPhone, Airbnb/Vrbo, Beyond Pricing (dynamic pricing), Your Porter for automated guest communication.

Other than that, cameras help.

You could always install a no trespassing sign with a security camera and have them arrested for trespassing and theft. 

Some landlords in my market are doing "self-guided" tours of apartments with lock boxes and a security camera or two.  

What I did and it actually worked was put a wireless (ring, blink, etc) camera right above the garbage with a sign to "monitor" any illegal dumping.

If it is multifamily, I would install security cameras.

The sellers disclosure claims he has no knowledge of any issues with the home however, there are camera holes in the baseboard with sawdust below.

You may hire a plumbing company to run the camera if you wish,  normally that costs around $200.  

Inspectors are able to send cameras down the drains to get a better look.

I don't like battery operated cameras.
