I remember a couple of years ago when Zillow first hit the real estate scene. Consumers embraced the web site almost immediately because of the web site’s cool, on-line tools. One tool in particular caught their fancy: the Zestimate. This single, funny-sounding word would grow to strike fear in the heart’s of REALTORS® everywhere.
But what is a Zestimate? A Zestimate is an estimated market value of a home based on Zillow’s proprietary, mathematical formula. The home data they compile to generate a Zestimate home valuation varies by location. Some geographic areas provide all the data Zillow could hope for, but others are lacking such key things as the number of bedrooms and bathrooms, or, in some cases, the square footage of the home. The theory says that the more data Zillow has, the more accurate the Zestimate. They even made it easy for users of the site to help them improve accuracy by incorporating edited home facts into their Zestimate calculations. In some areas, Zillow can’t produce a Zestimate at all, but they do have some basic information on the homes.
Why did REALTORS® dispise Zillow? Because they claimed that the tool that produced Zestimates oversimplified the valuation process and gave inaccurate results. Regardless, Zillow shot up the popularity charts and in no time at all it was firmly entrenched as one of the top ten real estate web sites in the world. REALTORS® looked at the new kid on the block as a threat to their own personal fiefdom as experts on property valuation. They exclaimed, “How dare they hand out FREE property estimates! They’re misleading consumers. Why can’t consumers see that the accuracy of Zestimates is atrocious?”
