It will sharpen your BS detector so you will avoid paying big money to learn common sense 101 "strategies" and "secrets" packaged with a lot of hype.Anyway, that's all I've got for now. 

Prepare to unload and change to stricter mentality if things aren’t worked out once things are back in motion and eviction courts are caught back up.

-There is previous water leak spotted in chimney siding -Low water flow rate even though water pressure checks good - hot water heater is working but old - windows probably need replacement some don’t stay open and one window can not open at all -new smoke detector needed -ac thermostats works but is miss wired -few small electrical works I am gonna call my agent and discuss possible price reduction or have them fix some of these issues.

One rental house automation I will add is "if it's between sunset and sunrise and the driveway motion sensor goes off, turn on the stairway, main door, and under house lights, then turn them off 10 minutes later". 

My wife and I both get an alert if there is motion. 

Rules for such things as: how often to change HVAC filters, redo paint jobs, have a gardener come, check smoke detectors etc.Should I have the tenant or landlord pay?  

Motion sensor lights, trail cameras, Simpli Safe, junkyard dog. 

Damaged or missing smoke detectors, CO detectors, or extinguishers6.

You're going to have to mess with cords anyway if you want cameras that plug into power outlets and have features like motion-detecting spotlights, which have clearly been a very effective crime deterrent for us.

Verifying if smoke detectors are functioning, appliances are running and water pipes are not leaking is a plus.
