I know how you feel, years ago we bought our first house next to a
rental, and the tenants from hell moved in. It was a government
rental too, and they told us as long as they were paying rent anything they did of a criminal matter was for the police to deal with. They would light bonfires, sit outside drinking with the music up, and when my ex husband actually asked for them to turn it down, he woke up to his tyres slashed the next morning.
