That is an excellent suggestion!

I was an Underwriting Manager for a national insurance company for a while and know a little bit about personal property insurance. By moving in a very few items of furnishings, a place to sleep and minimal equipment to prepare and eat a meal, and by spending one night in each 30 day period at the house, you change its classification from "vacant" to "unoccupied". This can make a huge difference in coverage and premium.
