Plumbing winterization complete. Do I need to keep heat on ?

[Manmath D.]

So my SFR did not sell as expected. I do not want to put it back on rent. Will list it in spring 2021. My realtor has set heat on at 60 degrees. Plumbing was winterized today, and I was wondering if it was ok to turn off the heat in the house. One less bill to worry about. Heating bill is high where the rental is. What would you do ? Thank you.
