Hide properties on Zillow! With Whittle you can create and manage a list of properties to hide. Sites like Zillow only want us to use their "Favorite" system, but sometimes it's useful to clear out homes that you would never purchase (even with a gun to your head) from clogging your search feed and maps. Whittle provides what is basically a reverse of the "Favorite" system, whereby you can block properties from showing up in any of your searches instead. Allowing you to essentially *whittle* down your searches instead of building them up.
