Why You Shouldn't Trust Zillow Zestimates

I recently had a couple of clients whose Zestimate on their home was $681,000. However, it showed that same property had sold for $215,000 two years prior. Apparently, my clients had sold another property two years ago for that price, but it was nowhere near it and had nothing to do with their current home. For some reason, the tax information that Zillow obtained was applied to the information it had on their current home, which I assume greatly affected the current Zestimate.

So how accurate are Zestimates?

Zillow reports that the median Zestimate is off by about 5% of what a home sells for.  So, for my clients’ home with a $681,000 Zestimate, the value could be $34,000 higher or $34,000 lower. That's quite a difference.  

 

  Getting your home on the market now will expose it to more buyers.

 

 

A recent article I read that was written by an economist and real estate agent on realtytimes.com stated that 10% of Zillow’s Zestimates were off by more than 20%. On a $300,000 house, that means there’s a 5% chance Zillow would give you a Zestimate of $360,000 or more. There's also a 5% chance Zillow would give you a Zestimate of $240,000 or less. You can read the full article here.

Zillow’s site even states that the Zestimates are a starting point, which means they are more for entertainment value than for true value. Zillow also states that in order to get the true market value of your home, you should contact a real estate agent who will do a comparable market analysis or have an appraisal done.
