While we're at it, lets also figure out why my Zestimate dropped $40k overnight two months ago. If I was planning to sell, I would have a huge problem on my hands. On top of it the Zestimate chart shows no indication that they dropped it $40k. Aiming to fix the number is a fool's game : my "private home estimate" on my owner dashboard is 23% higher.
Its a worthless number, and they should stop trying to manipulate the market. Having a secret measurement formula that works for 70% of the houses but not the other 30% needs to either have a disclaimer that its all fantasy, or just outright be removed. I'm guesstimating those 70/30 numbers, but their site gives some locations 2 stars on their own scale: http://www.zillow.com/zestimate/#acc. If its not 4 stars, then don't publish it.
