You also mentioned Smart locks in your article.I also use Digital Watchdog camera/security system to keep an eye on the property when no one is supposed to be there or to make sure the amount of people isn't double what they said or if they are sneaking in pets without a pet fee.Honeywell 9000 color touchscreen wifi thermostats.

(larger number pad on the thermostat) How about 65%?

We have successfully bought  rundown properties off the MLS,  upgraded them (tile bathrooms, newer fixtures & appliances, new windows,  extra insulation, programmable thermostats, etc.)  

Now I'm not an expert, but the scope of work seems to be something like the following:A-CoilCondensers + concrete pads + copper lines220 electrical ran to said condensers + breakers (my panel does have room in it)Charge system with coolant (needs to be done by licensed professional, understood)Run wire for thermostats (no new thermostats needed - have been upgraded and are compatible)I'm getting quotes upwards of $6k.

What about people that pay utilities on your units... do you have digital thermostats with a floor and ceiling for temps?

My thought would to also include all the manuals for appliances, thermostat, water heating re-lighting instruction, and possibly even copies of the move-in property condition photos.

Also, you'd have to account for the cost of two new boilers, installing electric, individual thermostats, running separate gas lines to each unit, etc. as well.

After that, use a channel manager (IGMS, Your Porter, Smartbnb) for automated guest messaging, dynamic pricing software for pricing (Beyond Pricing, Pricelabs), a digital guidebook (Touch Stay, Hostfully), install a camera on the exterior to monitor activity (in case you rent to 6 and a group of 15 shows up), use a WiFi thermostat and possibly a keyless entry lock on the front door.

If it takes time to get to 68 then maybe you should leave the thermostat above 68F.
