They cover most of the Valley, and my properties are in Tempe and Gilbert.

Basically it is more expensive to fix places up in AK than where I live due to high labor/material costs and you have to build for -20F temps, snow, etc...

In the back country of SD there are hundreds of these unpermitted units I'm sure, but none of them are permitted...or they were permitted at temp RV spaces for visitor stay.

It’s on their contract they should keep the thermostat temp at 72, anything lower than that could cause it to freeze therefore costing them hundreds of dollars and trust me prior to having notes underneath of it n to have mentioned it on the contract it did cost me hundreds of dollars to fix it!

I'm East Valley so I typically see these in older parts of Tempe, downtown Chandler, downtown Gilbert or all over in Mesa.

This is not surprising given how far prices rose in 2021The top performing cities based on comparing the annual average $/SF with the same measure 12 months ago are:Carefree - up 25.5%Paradise Valley - up 24.7%Fountain Hills - up 24.4%Coolidge - up 23.4%Wickenburg - up 23.2%Cave Creek - up 22.2%Scottsdale - up 21.7%Youngtown - up 21.2%Gold Canyon - up 20.0%Avondale - up 19.9%The bottom of the table looks like this:Maricopa - up 16.0%Waddell - up 15.7%Sun City - up 15.5%Eloy - up 14.5%Tempe - up 13.9%All the other non-trivial cities are up between 16% and 20%."

However, if I understand your post correctly, ambient temp/humidity was not very high during the period, so you might also have a leaking water heater.

In upstate NY, I still find this a rare occurrence as most people don't want to move when the weather and temps can make it more of an ordeal.I have only ever done MTM leases for my rental units and it has served me well.

We also do STR in Tomah, WI which is a couple of vacation stays or one-two night stays for people stopping off the highway, but is mostly month-3 month long stays for traveling nurses, laborers, etc. working temp jobs. 

I moved my daughters to the Tempe area and their rents are increasing, my goal is to purchase a quadplex and rent the other units out too.
