It won't strain your eyes if you open the larger copy that was referenced.
I was mearly providing the data to show that the Realtor® posting had no clue what he was writing. Unfortunately, that is often what you get from members of the National Association of Realtors®.

If they don't answer their customer service requests, what makes you think they will look at a 'report a problem'.
You can spew out all the eye straining charts you want. Their data just stinks - to keep this a family website.
Gotta Love it ... now my home is up $50k in the past 3 weeks after coming down over $400 k in 6 months..

The IPO money is only 2.5 million shares at $20 per share, and is only short term operating capital; and nothing compared to the investment of the original venture capitalists.
In addition to contacting customer service, one can use the "report a problem" button under the edit pull down tab under the main photo on the home details page, if you believe some of the "recently solds" used in the modeling either shouldn't have been used (due to being empty lots, bulk sales, family transfers or distressed sales) or possibly have copying errors in the public records info.
As for the estimates being at the bottom of the value; that is just plain false. They are equally likely to be high as they are to be low. Here is a comparison chart just for my city comparing the list price to the estimates (created when the "list mode" search results were available, thus prior to the last major revision of the estimating modeling):
Enlarged; for the ≤$1 million listings, ±40% difference range:

For under $2 million, both the average and median difference is "zero". (Homes valued over $2 million are harder for the model to capture based on sparse sales data; but the revised algorithm does a bit better).
By the way, the deviance is not only in the estimate to market value, but also in the list price to market value. Numbers are published for the deviance of estimate to market value for each county and each metropolitan statistical area. For list price to market value, the best data available is on the "local info" pages; but that only gives an average and nothing to define the distribution.

Hey wetdawgs,
I sent a legitimate request/complaint to Zillow customer service over a month ago, got an automated response with a request number on it (so they acknowledged receiving it.), and nothing since.
They are counting the money from their IPO and don't care about the quality of the data they spew out.

Zillow's Zestimate is at or around the bottom value of a given property. They state "it is a starting point" for value. I wouldn't get worried or bothered about their valuation. What does matter is what your appraiser, the bank, and a buyer thinks.
