Zillow does a major change in its estimate, which affected to many house, however, your home is still worth at $974K.

The thing about Zillow is, the data that enters the Zillow system usually takes some time to get there. For example: I sell my home on Comet Dr (Foster City) on 1 June (transaction closed). It gets recorded on June 3rd. This sale normally won't reach the Zillow Database for weeks (sometimes a few months) after the sale is recorded.
Once it does catch up, it will adjust the estimate for each home in the area a little, or a lot this there's a big price disparity from the norm. Now, picture several sales catching up around the same time. This will explain some of the significant changes you'll see, as well as a change in data from 2 months before, because thats when the sales actually occurred.
Try to use Zillow for what it is: a ballpark estimation. If you need a tighter estimate, any Realtor can do a Market Analysis (CMA) for you that is essentially the same as a Zestimate. The difference is, the Realtor has access to real time information on home sales.
So, I recommend you contact a Realtor for a really good idea of your value. Almost all Realtors will do this for you for free, and a few of us will do so without hassling you for a listing afterward.
Hope you find this helpful.

zestimate change or system issue???
Is that zestimate changing past data or system issue???
Either way it shows there should not be trust in your data. Especially, if you keep correcting your past data.
