ZestimateI have duplex and Zestimate for our house is going rapidly down and today was 12K down in last 30 days, but my neighbor ( second half of building) is going down only $253 in last 30 days . Neighbor from other side (next building) down $2926. So, can anybody explain me differences ?April 18 2014 - Ponte Vedra Beach00YesReport a ProblemProblemSelect oneOffensive contentIrrelevant contentSpam (pure self-promotion)OtherDetailsYour emailPlease enter a valid email address.Submit CancelContent flaggedWe will review this content.
