Vinyls are also less stable to temperature swings.

The average lead temperature is "warm" for direct mail and it takes about 40 leads to convert one into a deal, so it is not worth your time to do direct mail unless you can commit to at least 4,000 mailers per month.

I don't like hardwood flooring in rentals because: 1) They are expensive to buy and expensive to install; 2) They require maintenance; 3) Re-finishing floors is also expensive and extensive; 4) They are not water proof/temperature proof and will buckle/warp if there is excess moisture from a leak etc. ; 5) Pets may leave gauges in the flooring from nails; 6) Compared to LVP they do not add any more $ in value LVP is nice because: 1) It's less expensive and easy to install; 2) Is water proof and scratch proof; 3) The thicker wear layered planks i.e. 12mil or higher will last longer than hardwoods unscathed; 4) its pet proof; 5) In the off chance that many years down the line there is wear on the floor, you can replace them still for cheaper than you can refinish hardwood flooring, and its a new floor again. 

Some other things that might help: programmable keypad locks for remote entry (I use Schlage locks), HVAC system that has an app where you can control temperature when no guests are there, and reliable internet.

I finally gained entry to the house and the temperature was over 100 degrees.

I came from Kentucky so any temperature above freezing is great in my book.  

It’s generally a problem in winter when a small apartment is fully sealed, having a temperature of 72+, and cooking is in progress.

They will continue to fall with the temperature.   

Regardless of the system they are temperature sensitive, so you have to treat them like a computer.

If not, think about installing landlord friendly thermostats that max out at a certain temperature then drop down over a few hours.
