Metrocosm, a real estate data blog, estimates that roughly half of the total property value in America comes from five states: California, New York, Florida, Texas, and Pennsylvania respectively.
To visualize just how concentrated property values are in America, Metrocosm created a cartogram, or a map that resizes each state in America based on which ones have the greatest residential property value, which is also a reflection of the most populous places in America.

An even more striking way to view this disparity in property values is by making a cartogram that substitutes county land area with residential property value, which Metrocosm did in the GIF below:

Finally, here is another cartogram that shows the disparity in residential property values in neighborhoods in Manhattan as well as the other four boroughs:
