Realtor fag here. When a for sale by owner (FSBO) sells a home they are not obligated to follow most license laws. They can pick and choose who comes into their home versus listing with a Realtor. If I had to bet I would say Zillow is being used like wayfair was and it would be less obvious than wayfair. There are 1000’s of properties on Zillow FSBO. I have no sauce, and I can’t dig. I hope one of you Anons can. Zil means island (we know what happens there) and there is all kinds of fuckery associated with “Lo”.
