It's a 3 bedroom house and we plan to use technology such as a smart lock, WIFI exterior cameras, and a smart thermostat.

I flew there and walked the house, looked pretty turnkey rental grade): $1029 GFCI outlets, downspouts and guards, drywall, paint, bathroom vent$4615 (new AC unit since unit was stolen before tenant moved in, didn't file insurance claim because didn't want my premium to go up) $600 (water line, gas line, P trap)$60 lawn mowing$112  thermostat repairMy opinion is that Class C is better for local investors who are on site and know how to do repairs and self manage.

Kitchen cabinet handles were placed upside down, cabinet doors were installed backwards, electrical line for thermostat was ran on the inside of the bedroom exposed, trash swept into newly installs vents from the furnace, cracked tub, wall switches were installed sideways in some rooms, wall outlets were installed upside down on some walls, list goes on.

Smart Home FeaturesAdding smart home technology like thermostats, security systems, and lighting controls can increase a property's appeal and value, especially for younger buyers.8.

You also might want to consider remote thermostats in case one tenant wants freezing AC and the others don't.

And as John said, have as many remote/wifi controls like locks, thermostats, garage door openers, sprinkler controllers (I don't have cameras, but many do).

If you’re still concerned, you could consider installing programmable thermostats or low-flow fixtures to help control costs without relying entirely on tenant behavior. 

Aside from the financial resources, I suppose one skill is I write algorithms to distill signal from bulk data for a living, so if there are any other programmers out there please reach out!

@Jeremy Bloom  the rag on the thermostat can be beat by placing a remote thermostat that is set to the legally required temperature with that remote thermostat actually controlling the temperature.

Like someone else mentioned, doing a short term rental in a secluded basement that is very private and walled off is one thing, but sharing the same refrigerator, kitchen thermostat, etc. with a complete stranger seems like it will introduce more problems than what the money is actually worth.
