this was back around 1991, but may work for your situation.

neighbors moved from Louisiana to Georgia, and house was vacant

they paid my brother to "live there", and occupy the house

they kept utilities and phone on, we just changed the phone number to his
name

real estate agent loved the idea, he just rolled up his sleeping bag and
stashed it in the utility room for open house.

and it was convenient for real estate lady to have access to a phone when
she was doing open houses.

house was right next door to us, and was nice to have extra room when we had
out of town company..... call furniture rental place, and had them a nice
bedroom setup for 2 weeks, saving hotel expenses.

lady that bought the house is still there... her hubby got sent packing
sooon after they moved in
