According to Business Insider, a home that has become known as "The Watcher" house was just sold for a little under a million dollars (and at an over $400,000 loss for the sellers).

In 2018, TheCut.com published an extensive article about the home, which is located in Westfield, NJ.  The articles said that shortly after purchasing the house, the owners, the Broaddus family, started receiving eerie letters from an anonymous person who became known as "The Watcher."  Here are just a few disturbing passages from the letters that were posted on TheCut.com:

"657 Boulevard has been the subject of my family for decades now and as it approaches its 110th birthday, I have been put in charge of watching and waiting for its second coming. My grandfather watched the house in the 1920s and my father watched in the 1960s. It is now my time. Do you know the history of the house? Do you know what lies within the walls of 657 Boulevard? Why are you here? I will find out." 

"All of the windows and doors in 657 Boulevard allow me to watch you and track you as you move through the house. Who am I? I am the Watcher and have been in control of 657 Boulevard for the better part of two decades now. The Woods family turned it over to you. It was their time to move on and kindly sold it when I asked them to."

Business Insider says the case was investigated to no avail by local police and that, "In addition to the $440,640 loss on the home they never lived in, the Broaddus family had spent thousands on renovations, security, and private investigators."
