The best is camera footage, although it could be something else like screenshots of messages that another tenant shares, etc.

Update lighting fixtures, install ceiling fans, ring cameras, etc...

Did someone put a camera down it to see exactly what's going on?

She installed a ring camera system and reached out to me highlighting that I was trespassing and that if she wanted her out, I would have to file an eviction.I did some digging to realize that she had a criminal history of doing this.

I'm certain I won't get every penny of my insurance payment back (had to pay 6 months in advance), I've had GCs and builders out to the space to give quotes, I did a sewer line camera inspection, etc. 

Add Wi-Fi thermostats, security cameras (exterior only), noise monitors.3.

If your investment is in a community that requires cameras, then it's not a safe community to invest in.

Most Security systems only maintain footage for 2 weeks dueto camera memory capacity.I.

A quick camera inspection by a plumber could confirm that.If it is the toilet, look at models like the TOTO Drake or Kohler Cimarron.

do you use cameras in the common spaces?
