How do I get an accurate Zestimate posted for my house?How do I know it is wrong? Because mine is at $688,000 and the virtually identical house (same age, same size, same builder, mirror image floor plan) next door is at $442,000. What's different? The $442k house is 100% original (and sold in July 2009 for $442,000) and mine has $150,000 in remodel upgrades (high-end kitchen, lofted ceiling, carport converted to garage, 3 of 4 wood burning fireplaces converted to gas, all new windows, skylights, etc.) And to top it off, a professional appraisal in December 2009 valued my house at $800,000.March 17 2010 - View Ridge00YesReport a ProblemProblemSelect oneOffensive contentIrrelevant contentSpam (pure self-promotion)OtherDetailsYour emailPlease enter a valid email address.Submit CancelContent flaggedWe will review this content.
