My little town is about to be taken over by moonbat black women....there's one running for city council in every district and they will win.........so that kind of Detroit shit will be coming here soon. 
Not sure I would handle this, If I left a home for a year but still paid taxes on it , not much different from retired folks that have a home in the north and head south for the winter and health reasons may cause them to stay away for a lot longer then a year. But is the home abandoned with the owners still paying taxes ??
So to the fact that someone is now living in your home. Now is the time to get Evil, as the strangers live there they are responsible for all utilities, so move in and hike the heat or ac up to high. Go to the dog pound and get a couple of baby pit bulls that are not house trained. Advertise that your home is open for garage rock bands to practise in.
Oh the possibilities here, a movie or a reality show.
