I am able to see major issues, but I don't take temperature of the cool air coming off the vent, I don't flush every toilet or turn on every faucet, nor do I actually run the dishwasher, or dryer etc...my inspection is visual.

Just checking the current temperature out there to see what lists everyone is having success with in the current market.

Temperature control:  It's always naturally cooler downstairs, and in the heights of summer and winter, I just cannot get the temperature regulated for both me and my tenant to where we're both comfortable. 

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

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...

Have you ever encountered someone from the northern regions expressing a desire to retire in a perpetually cold and overcast place where they'd spend their days shoveling snow in sub-zero temperatures?

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 :-)

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 supply temperature was 50°.
