Manhattan has gone Republican! Oh wait, wrong red-versus-blue map. What we have above is a look at PropertyShark's newly updated interactive property tax assessment map. The higher the taxes per square foot, the darker the red (or just pretend Central Park is surrounded by Commies). The lower the value, the darker the blue. A more mixed bag is PropertyShark's map showing whether the assessed tax values went up or down. Attention new Riverside South inhabitants: pony up!
