Zillow Advice: Zestimates - How do I dispute a zestimate? What criteria is used for updates? My zestimate went down $20,000! http://www.zillow.com/advice-thread/How-do-I-dispute-a-zestimate-What-criteria-is-used-for-updates-My-zestimate-went-down-20-000/444063/ Zillow Advice | Zillow Real Estate I've got the same issue and ... http://www.zillow.com/advice-thread/How-do-I-dispute-a-zestimate-What-criteria-is-used-for-updates-My-zestimate-went-down-20-000/444063/ I've got the same issue and I'm not seeing any answers from Zillow so far.&nbsp; Go read this article?&nbsp; That's not much of an answer.&nbsp; My house is way undervalued compared to all my neighbors; a house right&nbsp; next to mine that's 500 sq ft smaller than mine is valued at $3k higher, and I'm trying to refinance!&nbsp; My realtor comps show $23k more in value than the Zestimate, going by recent housing sales in my neighborhood.&nbsp; Zillow offers information on my house for all to see; therefore Zillow needs a little more transparency for homeowners to find out why they're knocking their housing values below the neighborhood averages.

You answer the same thing for every question about zestimates.&nbsp; <br/><br/>All the zestimates in my neighborhood have risen/lowered in proportion since FOREVER. I want an actual answer on WHY my house suddenly was lowered by $20,000. Since in the past, my neighbor's house picture had MY house number on it I am not trusting what is published in zillow. I've changed the number/house picture twice only to have it 'change' back to the wrong house.&nbsp;<br/><br/>It is patently unfair to change a zestimate for one house based on 'secret' algorithms leaving the owner with no recourse. Tell me how the zestimate was reached and maybe I'll understand.<br/><br/>Wetdawgs, are you a zillow employee?
