We have a couple of friends from the Northeast that rents our home for a couple of months and a family member from the Northwest that house sits the rest of the time. Rarely, rarely do we leave it empty. We have had freeze damage, tho rarely does it freeze into the teens, that could have cause big problems had the house been empty. During the summer the drip system stopped so the garden & trees would have died again if someone wasn't there. Just too much to lose if left empty.
