They cannot be wiped out by power outages, asset freezes, or cyberbrigades.1/3, 1/3, 1/3 was the basic portfolio of the Colonna family.  

It's all well and good to say "it's an asset not a liability" and all of the rest but none of that matters if the pipe bursts because of freezing temps in Ohio in the winter. 

In the event of sub zero temps (in our market) we walk through each vacant unit during the cold snaps to ensure pipes are not freezing and heater is functioning.

Also, I forgot to mention, there was one freezing day that my husband was at work and our pilot went out.

Just wanted to add to this that we rent single family detached, and we email tenants about cold weather requirements, how they should never turn the heat off in the winter, even during short vacations, remind them that our minimum heat setting in cold weather months is 59 degrees (in our lease), that they should leave cabinets and doors open to any pipes (laundry, sinks, etc.) that are near exterior walls to ensure heat reaches them if temps are going below freezing, and make sure they keep walkways clear and safe.  

The app freezes up and crashes.

I've read about the freeze burst resistance among other feature that PEX pipe offers, and it seems to be a really innovative thing.

Pipes can freeze to if the heat isn't on (also have too many stories on that).

Hose is connected to hose bib during freezing temperatures, causing the water pipe inside the house to freeze and split.All of these are tenant-caused issues and should be charged to the Tenant.

If there is any standing water in the lines, when the temperature drops below freezing, that water will freeze and expand, likely bursting the line while doing so.3.
