How reliable are Zillow data?

[Hyun Don Yun]

I am searching rental properties and realized zillow provides rental estimates and prediction of home values in the next year, etc.

not sure how reliable are these info. Did Anyone reference those data when buying and share the experience? Of course I will need much more info but wonder if it is a good start to rely on these data.

Zillow is trash data. CEO of Zillow sold his own personal home for 40% under the Zillow number. It was in the news if you want to google it.

ALL "automated valuation model" numbers are trash data. That's why we have appraisers, who certainly aren't perfect, but are 100x better than any AVM that exists.
