The thermostat is currently in the basement where the tenants can't mess with it but turns on and off based on the temp in the basement which is much different than the second story making it hard to regulate.

The home must not get too cold.The fourth is to use heat tape, this is pretty amazing stuff but it on;y works down to a certain temp so I would suggest not just relying on heat tape.Fifth, hose bibs are one of the biggest issues because they expose your water line to the outside temps.

About 90,000 individuals in the Milwaukee, WI area were left without power due to snow storms and below freezing temps.

With weather getting warmer and the number of days below the temp needed to make snow, ski seasons will become shorter and shorter. 

For now, since demo is done, I'll do a TEM air test and then scrub the property if we have any positive results, retest until safe, and then continue with the project.

We were very interested in trading it for a multiplex in North Tempe/South Scottsdale.  

J,I noticed your temp service on the last page, are you using an overhead service?

Temp was still fairly mild at 16.

@Brian Briscoe I can see how vacancies & thus rent would be affected in upper B & A class units, though I wonder if that would be the case in medium to low income or government subsidies housing where you'd expect less tenant migration during cold temps..
