The house is in CT, but it's been in the 40s this week and ground is not frozen solid.

The pipes/radiators have frozen and the boiler is shot, otherwise it looks to be in good condition.

This doesn't seem like negligence at all.Is the wall insulated outside the frozen pipe?

I asked the agent about problems like freezing pipes and she stated the property had frozen so the bank had the water turned off and then had someone winterize it hoping to avoid more damage.

As Steve Babiak mentioned, one was frozen.

Because this depends on the reasonableness of the tenant, there can't be an objective rating.I know that the reasonable tenants would rate me A or B, but then I have tenants that are unreasonable and get mad when I don't keep fixing frozen pipes, because they don't want to turn on the gas heater and instead hole up in the bedroom with a little space heater.I have low income tenants and they may not be unreasonable in general, but because they tend to live paycheck to paycheck it becomes a self-defense mechanism to blame me for things that are their responsibility.

If water or waste pipes are frozen, Tenant will notify Landlord immediately and in writing.

Well, if the tenant was supposed to pay for heating the place, and didn't have heat due to failure to pay for heat - then a reasonable conclusion could be that the tenant caused the damage that resulted from frozen pipes that burst.

When I'm not working or reading about real estate I can usually be found at my church, either working with our youth group or playing with the worship team, or sitting in my living room working on some goofy spoof of Justin Beiber or the Frozen soundtrack.

I live in Georgetown and maintain my own properties.I already had the trashed unit from an angry tenant, hail damage, frozen pipe burst so you could say I have already had my bumps in the road !
