Wireless and battery-free.

If the power goes out, you need a battery back up on your sump pump. 

For example, you can't give a holiday gift to only who you think are good tenants because one of them would post "Thanks Sam for the $25 AMC movies GC my boy friend and I saw Avengers last night xoxo" then your other tenants who didn't get a GC will feel left out.I visit my properties once a month for regular maintenance, mostly for little stuff, like changing AC filters, test smoke alarm batteries, test GFCI receptacles, pour bleach down AC condensate drain lines, exercise water supply stop valves, feel under any drains to check leakage, test water heater T&P valves, etc etc etc...they do not need to be done monthly but that's what I do at each property. 

My reason is that renters warehouse chargers me $79 a month to truly be a middle main and main point of contact to my tenants.  

It is much higher end than the wifi cameras you get in a box store.Mine are ethernet and get power over ethernet so I never have to worry about changing batteries.

It took into account servicing and battery replacement on the Tesla.

NO ONE IS ALLOWED TO CHARGE RENT OR MORTGAGE.

Solar panels on the roof charged several car batteries in the sun room situated off the front of the kitchen.

This is definitely a game charger.

Kenneth, it is not difficult to find a renter, but it is difficult to charge rent in the amount necessary to cash flow for your rental home.
