In the comment section at the website, there’s someone named “Kevin” claiming to be the man’s son. He’s claiming his father is not racist, that his father’s family is “multiracial” and that the whole situation stems from a “parking dispute.”
Of course, there’s no way to know if “Kevin” is whomever he says he is, or what the real story is. But...
This story caught my eye because I live in the same state, and 17 years ago a real estate agent told me that, per state law, the agent does not have to tell you anything about the neighborhood unless you specifically ask a question. For example, there’s a neighborhood a few miles away next to a toxic waste dump; the agents do not have to tell buyers what that “big hill with the flashing lights on top” is... unless they specifically ask.
It must vary from state to state. I saw something a couple weeks ago where a Californian sued and won becuase the previous owner failed to disclose nuisance dog barking in the neighborhood.
