I’ve been diving deep into the Zillow Home Value Index data to uncover the most expensive housing markets in New York State, and what I found was absolutely fascinating. The data reveals that Suffolk County dominates the luxury real estate market in New York, hosting 14 of the top 25 most expensive towns, with many located in the sought-after Hamptons area. The astronomical price points in these exclusive communities have shown remarkable resilience and growth over the past 15 years.
What struck me most was the incredible appreciation rates we’re seeing across these top-tier markets. On average, these exclusive communities have experienced an 89.78% increase in home values from 2010 to 2025, with a 63.90% increase just in the last decade (2015-2025). Even more telling is the 48.26% average growth over the last five years (2020-2025), demonstrating strong momentum even through economic uncertainties. Towns like Sagaponack, Amagansett, and Lawrence have seen their values more than double since 2010, solidifying their status as premier luxury destinations.
While analyzing this data, I couldn’t help but notice the geographic concentration of wealth. The eastern end of Long Island (particularly the Hamptons) and Nassau County’s “Gold Coast” communities account for nearly all of the top 25 most expensive markets. These areas have long histories as retreats for New York City’s affluent residents, and their continued price appreciation speaks to their enduring appeal and limited housing supply. The single Westchester County entry—Purchase—hints at the broader regional spread of luxury markets, but the dominance of Suffolk and Nassau counties is undeniable.
