They must keep the temperature at a minimum of 50 degrees F.

I've also leveraged their webhooks to automate additional things on my end like setting the thermostat to the appropriate temperature an hour before the guest check-in and turning it off after they check out.

@Collin Hays My favorite that came in at 6am one morning when the nights low temperature was 58 degrees and the high temperature was to be around 75 was the following.

My apologies for the lack of information - I was sort of just posting to get a temperature gauge for office rentals in general.

The tenant frequently informs me the interior temperature only reaches 68 degrees.

It might be worth talking to a lawyer but not sure if it's small claims or worth it.Also, you might already have all of these things but for future prevention:- smart thermostat (so you receive alerts when the inside temperature dips below whatever preset you have)- Minut (or similar device) would also alert you to the inside (and outside) temperatures; for example, I have 2 devices inside the house and outside on the hot tub deck.

It makes sense in places where it has temperature extremes.

If the temperature goes below freezing point, pipes might burst. 

I hope you or someone is at least keeping an eye on your properties for break ins, squatters, roof leaks, temperature control, frozen pipes (if in cold climate), if you have a basement and sump pump goes out leading to water damage etc.I just talked to two investors in California that have let their properties sit vacant (no mortgages so paying property taxes and insurance).

We took the highest month of "normal" winter usage we had records on -- people in the house, heat running at a reasonable temperature, washer/dryer running, etc.
