One of the sons wrote a tell-all book about the old man & it was not good. That might be the son you dealt with, because he was a psychological mess from what I remember....
Oh, I’d love to read that! Now that I remember, when I bought the condo, the president of the condo told me that the old man’s wife died in the upstairs bedroom (it was a duplex). She thought it was nice to inform me but I didn’t care.
