Wow, Probably you should leave a light on for night time, something not too obvious that people know you are not at home and just pretending to leave the light on.
There's no blinds yet either. They go in on Monday. So at the moment on the SS's suggestion there's a light on just so that anyone who does look can see there's nothing inside to steal. And also if someone does go in they are clearly visible. We've got the alarm on as well.
