Transparent pricing and financial reports are also important, as is understanding whether their management fees are charged before or after listing fees and taxes are taken out.A good property management company will also look for ways to streamline your guests' experience, such as by recommending smart locks and thermostats that make it easy for guests to access and enjoy your property.

I installed a wifi thermostat hardwired to the boiler system in the basement.

The smoke alarms, carbon monoxide, and thermostats, as well as an alarm in the basements to let us know if there is water detected. 

Open to ideas.I can tell you, the Nest Thermostats in my home save me about 150 - 200 bucks a month then my previous programmable thermostats.

I also use an Amazon echo that interacts with those smart switches and the thermostat so guests can even query thermostat temperature or change the temp via Alexa. 

Everything else can be handled remotely - keyless entry, Wi-Fi thermostat.

Thanks to@John Underwood I've gotten good tips from  for the wifi thermostat and camera.I see on some listings with leather and some with microfiber.

On my VRBO I have Honeywell wifi thermostats, Digital Watchdog commercial grade camera system and just added a Rheem wifi water heater.I see no value in adding any of these to a rental as it doesn't increase the rent I get on the unit and I don't pay the utilities.

One of my guys thinks we should add Nest thermostats, sensors, doorbells and outdoor and hallway cameras to the building and units. 

Putting in a smart devices doesn't have to be a big seed capital investment especially if it's just something like a smart thermostat and a smart security cam.
