I've seen these situations spiral out of control and lead to occupants neglecting/damaging the property, such as making holes in the wall to look for hidden cameras, nailing doors and windows shut, etc.

-Sauna-Hot Tub-Patio/courtyard (large cement tiles on crushed bluestone with lighting, natural gas line to bbq)-Secondary patio off primary suite-Losing sq feet in the primary bedroom to enlarge the bathroom-High grade cabinets-Appliances with cabinet fronts-High end appliances (Viking/Miele instead of GE Cafe)-Outdoor shower (teak box walls with a dry well beneath the footprint)-Wiring for Cat6 to every room-Wiring for surround speakers (or including the speakers that are built into the walls)-Sonos whole-home audio system-Hardwired cameras (with on-site storage) to the exterior of the house-Smart features: thermostats are a given, but how about light fixtures, switches, aromatherapy, fans ... anything else?

After my doorbell camera alerts me to check in, I look to see that it’s the same person.

I'm wondering if I'm missing anything: Mortgage (20% down, so no PMI) HOA Electricity Gas (None, as the new construction house has an electric stove—everything is electric) Water Bill Camera Security System Internet Lawn Care Regular MaintenanceQuestions: Will I need to pay for trash? 

One of my tenants have security camera facing other unit.

He immediately came back and started throwing large tree branches and other stuff on to my deck. i called the police a second time and they came and arrested him and gave me the report number.i have a security camera video of him throwing the brick, walking in and out of my property, screaming, and throwing the branches.what do i do to protect my workers and not lose my investment.

We will have heavy surveillance with video cameras on 30 foot poles in multiple locations.

You could be below market to the "average" unit in the zip code but if you're in the glide path of the airport with jets are taking off every 5 minutes, the Taco Bell parking lot lights shine right in the windows, freeway exit is two houses away, a busy fire station is nearby with sirens all night long, etc then the price may still be too high.Are there any safety issues that could be helped with lights, cameras, etc?

Whether it is litigation or surveillance I would do whatever it takes to protect yourself and your investment 

We also have a ~$100/month tech fee that builds in all of the subscriptions we use for each property (Ring cameras, Minut sensors, Price Labs, etc.).
