Why are there two different listings for our property?Hi,I live at 20 Willow Avenue in Salem, MA. It's 3 unit condo building. For some reason our property shows up twice on your website. And the zillow estimates are VERY different for both. Just wondering why there are two different listings and why they're so different.ThanksOctober 25 2012 - Salem00YesReport a ProblemProblemSelect oneOffensive contentIrrelevant contentSpam (pure self-promotion)OtherDetailsYour emailPlease enter a valid email address.Submit CancelContent flaggedWe will review this content.
