Since I invariably host, a provider could certainly glean a fair amount of information should they wish. One twink even checked my house out on Zillow and was impressed with its value! (Yikes!)
As others have mentioned, almost all of my hires over the years readily divulge many details about their personal lives and challenges. I’ve always been one in whom others confide safely. They rarely ask me much about my personal life, which is fine with me. I come from a family where discretion and privacy are paramount attributes. My discernment skills are pretty good so my “guests” have invariably been top-notch.
