One of the dangers of low winter temperatures is the threat of serious damage due to unheated water pipes freezing solid and then bursting when they thaw.
So it’s important to either continue to maintain the interior temperature of the house or to winterize the water system by draining the lines and adding anti-freeze where necessary.
My preference is that sellers keep the utilities on and the temperature set to the high 50’s or low 60’s. The reason is two-fold.
First, cold temperatures can cause other damage beyond the plumbing such as cracking drywall and peeling paint. Moisture can also build up in the house which can lead to mold and insect infestation.
Also, a house presents itself better to a buyer when it is warm and inviting. I have had buyers run out of houses many times because they were ”too cold” to look at closely.
Saving a few bucks on heating bills can cost thousands in buyer interest. It can really hurt both the number of buyers and the price that is offered
It just makes sense to me to keep the heat on!
