Erroneous and non-factual valuations. My home just dropped 30k in the last 60 days (12%). Their Zestimate history now has changed and shows the current Zestimate as the highest in 5 years. Previous Zestimates from as recent as 2 days ago which was 9k higher (yes, I dropped 9k in 2 days) is not shown on the graph. They are a total joke and should be put out of business. Harmful in many ways to the buying public. Banks do not recognize Zestimates as credible for loan purposes. This company needs sued big time!
