But Zillow Said...

One of the biggest thorns in my side is how Zillow offers to estimate home values for consumers. It never fails to amaze me how I can walk through a home, sit with the owner, apply my 13 years of experience to a detailed market analysis, quote the owner my best price opinion, and then be told with a straight face "but Zillow said it is worth $50,000 higher." I have had irate buyers call me at 9pm, almost screaming that they just overbid on a home because Zillow said it was worth $25,000 less.

There was a time that I just thought that Zillow hated agents. After watching the site evolve and reading Sara Bonert's writing, I no longer hold that opinion. I believe that Zillow does want to be a valuable tool. Sara tipped us off to Zillow's self-published accuracy statistics, which are very instructive.

According to Zillow's own data, in my own Westchester County, Zillow's median error is 18.3%. Now, this is Zillows own data, which to me speaks volumes.

What they are saying is that they aren't throwing agents under the bus, or that they are 2nd-guessing our local knowledge. 

Consumers who use this feature would be well advised to read the small print and take this into account when using the zestimate feature. Knowing that this transparency is evident at Zillow gives me far more peace of mind in dealing with their valuations.

Perfect!  This is exactly how I hope Agents are using this chart and data.  We believe in 100% transparency for the real estate consumer, which means holding ourselves to this standard and being upfront about our accuracy.  Thank you so much for reading and hanging in there with us.

18.3%.

What is the point then, really?

The problem is that most people, myself included, don't usually read the small print, at least not on informational web sites.

These values clearly can present a head wind when talking with buyers and sellers.

The evolution of Zillow is obvious...at first it did seem there were anti-agent.

As I tell my students, beware of statistics...ask how old and from whom.

Thanks for sheading some light on Zillow.

Have you seen the estimates being shown for foreclosures on foreclosure.com (I think that they are Zestimates, but not certain)- the values are ridiculously high.

some of REO asset managers use Zillow to compare value when they order BPO
