how are houses are evaluated and zestimates givencan you tell me how this home located at 3329 coy drive CA 91423 is zestimated at 1.8 and a very similar home which is actually bigger and newer at 3260 coy drive CA 91423 is zestimated at less than 1.2 ? just wondering how you calculate these numbers because this seems very strange. thanksOctober 17 2011 - Sherman Oaks00YesReport a ProblemProblemSelect oneOffensive contentIrrelevant contentSpam (pure self-promotion)OtherDetailsYour emailPlease enter a valid email address.Submit CancelContent flaggedWe will review this content.
