The issue in GetHuman1219343's own words
Zestimate is influenced by outdated (* -*** yrs ago) and erroneous sales. My property value is heavily influenced by its proximity to water, its waterview and its deeded waterfrontage. Many of the comps used re my zestimate have none of these. The graph of values over the years is completely insane! It has my homes value at ***,*** seven years ago. The house sold for almost ***,*** some *** years ago. The "Inside the Zestimate" information from the local tax authority is more correct re the value because the locally derived assessed value (which takes into account many points your algorithm does not) is equated with a multiplier which more corresponds to a property's potential sale price.
Zillow should remove the comp sales without deeded waterfrontage and weight waterfront and view property more heavily.
I have an issue with Zillow too
