Property Values Heatmap

[Donny Hodgkinson]

Hello Everyone,

I'm curious if anyone has come across any online tools that display a heatmap of property values in a given area?  In other words, a tool that allows the user to zoom into a city/neighborhood and see estimated property/parcel values and have those values vary in color, much like conditional formatting in excel.  I know Zillow will display the Zestimate values of properties, but if one were to extrapolate this data and overlay it on a map it would make comp analysis much, much quicker in my opinion.  One could easily see high vs low end neighborhoods, view trends over time, etc.

I use heatmaps quite a bit in my line of work to quickly find trends/errors to help analyze data, and am curious if anyone uses it yet for property analysis?

Any insight is more than welcome!

Thanks,
