Maybe have them sign a statement they will vacate and they will not put up no tresspassing signs nor will they sue them for rights of property after their time frame of rental.
I would also put in the contract(lease) that all utilities will be disconnected at the end of the rental period since the house will be vacant. I would also put in that generators are not permitted on property (in case they think that will be a work around). An alternative would be to make sure you arrange for major work to be done at that time if you have the money and were planning on it anyway. Loud work with a lot of people coming and going for days.
If that would be legally enforceable.
Maybe digital locks with the entry code that can be reprogrammed remotely. They’d just break the window or the lock itself somehow most likely.
