Compared with residents of most nations, Americans live in fabulous wealth and splendor. But some neighborhoods take it to the next level.

In these places, the average selling price of a home is well beyond seven figures. In fact, in the nation’s top 10 most expensive ZIP codes, the average selling price is at least $4 million. In the very toniest of neighborhoods, it is well beyond that number.

Recently, PropertyShark crunched the numbers and uncovered the 100 most expensive ZIP codes in America as determined by the median home sales price during 2021. Following are the areas that topped the list.
