(9) Talk to the gas company about disconnecting the gas supply. Possibly a gas explosion if the pipes freeze. If gas leak appears has to be fixed, but often happens on the week-end. (10) make the house appear occupied at a glance. Set up lights on timers, have landscaping done, if snow then shoveled away. All of this for non-occupied and occupied homes. Also will have to be un-winterized on fairly short notice for inspections. GOOD LUCK ON THE WINTER CHORE OR NECESSITY TO SELL A HOME.
