Air circulation should keep the temperatures close to even. 

It will make you a more credible filter, temperature, and well grounded person!!

I would think the same laws apply that as long as the property is within the legal temperature limits shutting it off isn't an issue.

The temperatures you have the house at are completely unacceptable.

The supply temperature was 50°.

Wow, This post was exhausting and I was debating if I'd even respond, as the temperature of the conversation is condescending and argumentative which eliminates any chance of a resourceful conversation...

Trash removal and proper handling; not allowing food or cooking/heating appliances in bedrooms; temperature controls; yard maintenance, shoveling snow, basically anything that you need to tell your kids to do, you need to have a plan for the residents.

Of course, possum have a lower core body temperature = they almost never gets rabies and are not aggressive so let's just say a possum has nothing to worry about if it's caught by me :-)

For instance when it's REALLY HOT in Saudi Arabia and the middle east, or inundated with rain and snow in other parts of the world, coming to Orange County where winter temperatures are between 68-72 during the day, is a welcome change, and we don't have hurricanes! 

Assuming your tenants pay for electricity, boom, they pay for heat, and they can have their apartment at whatever temperature they want.
