How do we come up with the Zestimate?
"We compute this figure by taking zillions of data points - much of this data is public - and entering them into a formula. This formula is built using what our statisticians call "a proprietary algorithm" - big words for "secret formula." Currently, we have data, Zestimates and Rent Zestimates on approximately 100 million homes on Zillow."

Zillions of data points & a "a proprietary algorithm" - big words for "secret formula." ......Impressive ;)

The FAQ "Valuation Tools" provides background on the Zestimate. As an outsider, there are two things I always look for related to Zestimate calculations:
1. Are there missing data? In the property mentioned, no lot size is shown and providing that may help the calculation.
2. What is the value range? For the home in question, the value range is $192K – $621K. This wide range supports the hypothesis of missing data for both the home as well as sparse data in the community.
Zillow Academy offers a number of training tools free including background on Zestimates for agents.
