how does zillow come up w their estimate

my home is 491 miller place rd, miller place, ny 11764 with a zestimate of 448,000 the homes on both sides of mine, are much higher then mine and not much different .  the birds eye view picture is not updated. since that picture we have done lots of work to our home. 495 miller place road zestimate is 527,000, that is a 79,000 dollar difference that is not at all possible.  your website could be detrimental to the sale of my home.  i would like an explanation!!! and something has to be adjusted.  my email is mcm478@yahoo.com. or phone # 6318603221.

Thank you,  Michelle Sebald

If you go to the 'help' section under "more", you will discover more details on how Zestimates are determined.

Zestimates are not appraisals, and only a starting point in comparisons.   (very few people are happy with their Zestimates these days, but loved them a couple of years ago!)

If you claim the home, you can enter facts showing the details of the remodeling.  In the next few weeks, the Zestimate may change reflecting the upgrades. 

The bird's eye view photos are from public data bases and can be as much as 3 to 5 years old.  They cannot be updated on demand.    If you have done substantial remodeling, the best way to reflect it is to claim your home and upload your excellent pictures.

Zillow uses aggregate data from public records.  They do not view your home, they don't take upgrades into account.  You can log in and change your home's details.
