All year long, I’m buried in research and data, looking for stories that help shape Connecticut’s identity. If you live here, you know our state isn’t just a cliché of yachts and country clubs. Still, I’m often surprised to find entire regions in the U.S. that are even more expensive to live in than some areas here in the Nutmeg State.

Just this morning, I came across an article about the most exclusive towns and cities in America—and my jaw dropped when Connecticut didn’t even make the Top 15. But later that same day, I found a piece that made much more sense from Cash for Home.

What is the Most Expensive ZIP Code in the U.S.?

While we may not be the richest state overall or home to the wealthiest counties, we do claim the most expensive and exclusive ZIP code in the country. That’s right—if you thought California or New York had the most expensive real estate in the country, think again. A new study shows that the title actually goes to Connecticut — specifically, the upscale town of Greenwich.

Greenwich’s median home value is a jaw-dropping $1.94 million, making it the most expensive ZIP code in the entire country. So, what’s driving those sky-high prices? It’s a mix of classic Connecticut charm, close proximity to New York City, and a long-standing reputation as a haven for hedge fund managers and financial elites. I used to think hedge funds were literal bushes where rich people hid their money. They aren't right?

The study, conducted by Cash for Home, looked at over 3,100 counties to find the most expensive ZIP in each one. From mountain towns in Wyoming to beach escapes in Hawaii, luxury living can be found in every corner of the country. But in the battle of ZIP codes, it’s Connecticut that takes the crown.

I used to work with my dad's friend Bruce delivering homemade pasta to Greenwich. Does that count for anything?
