how do you sometimes get totally eroneous sale pricesI did a search for comps in San Rafael, CA for a home on Devon Drive. Almost all the comps were in a very similar price range, except two, each of which was about $1 million higher than the rest. I double checked them on the MLS and they were off by $960,000 and $1.1 million. My question is whether those two errors effected the Zestimate on other homes in the area?October 06 2009 - San Rafael00YesReport a ProblemProblemSelect oneOffensive contentIrrelevant contentSpam (pure self-promotion)OtherDetailsYour emailPlease enter a valid email address.Submit CancelContent flaggedWe will review this content.
