Greetings everyone,For those of you not here right now, I write this as temperatures in Chicago have gone from the 80's to the 50's in a matter of days.

Because they pull heat energy from the outside air most basic heat pumps are able to generate heat with an outside air temperature range anywhere from 25-45 degrees.

If they cannot produce a receipt for the hotel, I would give them each $50 or $75 off next months rent.I just looked at the temperature for your area, the tenants have a legitimate complaint.

Our state guidelines say we must maintain a temperature of 65 degrees.

But, no penalty.Pick up a couple of these and see what the actual temps are during the cooling cycles:https://www.amazon.com/Elitech-RC-5-Temperature-Reusable-Rec...Keep in mind, NO AC can cool more than about 20 degrees below ambient.

The temperatures you have the house at are completely unacceptable.

At a glance, a pool would serve more guests, especially in hot temperatures like the markets you mentioned. 

It is a good time to buy multi-family now in Central Texas because the COVID-19 virus does not like the heat and come August we will see Texas and its 100 degree temperatures start to heat the real estate market up again, as the cities start opening up, and that means multiple offers with properties selling above market price.  

They only turn on when the temperature drops to freezing levels and plug into a standard outlet.

Tax benefits for the most part take care of themselves if you have at least a room temperature IQ.
