Zillow is a scam if you are selling by owner. They do not show FSBO listings to buyers, unless the buyer knows to change their settings to show FSBO listings, otherwise they are hidden, and only shown to realtors and investors, who then blow up your phone with calls and text messages, dozens a day, wanting you to list with them or sell for half price. I listed for three months and had no calls from buyers. All of my legitimate buyer calls came from my sign on the property.
