It isn't just realtors that Zillow hurts. Their zestimate is nothing but the roughest of guidelines. It is little better than a general market trend in a geographical area. I am not a realtor, but a homeowner who learned, from experience (buying and re-financing my own home) that Zillow is useless. I can understand if it causes homeowners to set unrealistic expectations regarding the value of their property, because, lets face it, there are a lot of "unsophisticated" home owners / buyers out there. Some of these homeowners / buyers make life decisions based upon bad information. Yes, they should know better, but many don't. A home buyer / owner is looking for trusted authority for their property value. The only legitimate authority to make that determination is an appraiser. Zillow puts themselves forward as a trusted authority, which they definitely are not. The unsophisticated buyer / owner sees them as a way to avoid paying for an independent appraisal. But mistake.
