The up keep had become too much on the old place. The roof was holey, letting the wind and rain inside to play. The wood groaned with bugs, causing the house to shift around. Windows cracked, doors left hinges, floors humped, walls bulged, ceilings dripped and inhabitable called.
People moved out, but nothing could be done with the place. Nobody would buy the house, not even for the land because there were documents and protections on things. So everything was left to to sit. Time and nature were allowed to do their own things to the place, no cares given.
