Why is my estimate way off?Hi,We purchased this home last year for 89k. At the time, the zestimate said it was worth 91k. However, around that time of year on the current graph, it says it was worth on 79k. Also, now it's only worth 79k, when comps in our neighborhood have sold for 130k, and the "similar homes" on the site list homes for around 90-95k. I just need help; I'm not angry, just trying to figure it out. We're trying to refinance soon, and I'm afraid an appraiser would do the same, resulting in no equity.July 06 2011 - Springfield00YesReport a ProblemProblemSelect oneOffensive contentIrrelevant contentSpam (pure self-promotion)OtherDetailsYour emailPlease enter a valid email address.Submit CancelContent flaggedWe will review this content.
