So, I don't think frozen pipes were a concern.

I've lost count of the number of RAD investors who posted in the BiggerPockets forums about their "hard money loans" and then having their distributions "frozen".

Guest left all windows and door open in our cabin in -15 degree weather when they left causing a frozen pipe.

Grocers must eat the loss of their fresh vegetable or frozen foods during a power outage.

I hope you or someone is at least keeping an eye on your properties for break ins, squatters, roof leaks, temperature control, frozen pipes (if in cold climate), if you have a basement and sump pump goes out leading to water damage etc.I just talked to two investors in California that have let their properties sit vacant (no mortgages so paying property taxes and insurance).

I cant tell you how many rescue loans Ive underwritten for small businesses who relied on a LoC for liquidity and then had the line frozen or called unexpectedly.

So you don’t end up being the cause of frozen pipes.

Selfishly, being able to respond fast, mitigates damage to the property (frozen pipes, mold!)

In the northeast having a second heat source in the rental saved  frozen pipes when the electric was out for days.

I once rented a 5bed/3bath in two days, just a week before Christmas when the ground was covered with snow and ice.Sitting vacant in the winter increases the risk of frozen pipes or other expensive problems.
