While that's nothing to sneeze at, the most expensive neighborhood in Illinois will make you gasp.

For Illinois, I was kind of surprised. I half expected a city like Winnetka or at least a zip code in Winnetka to take the top spot. Actually, the place is only a four-minute drive away.

The most expensive zip code in Illinois, and inside the top ten for the entire country, is Kenilworth.

Cheapism:

The small and wealthy North Shore suburb of Kenilworth has been the richest ZIP code in Illinois for several years running — the median home sale price breached seven figures in 2016. The whole North Shore, actually, is complete with communities that are among the richest in the state.
