Long Island has outpaced Westchester as the location of New York's most expensive places to live according to a recent study. The detailed report from GOBankingRates ranks the top 20 suburbs in New York state by the monthly cost of essentials which includes mortgages, groceries, utilities, health care, and transportation. Using data from sources such as the U.S. Census American Community Survey and the Bureau of Labor Statistics, the ranking positions Sands Point as the priciest with an average monthly cost of basic needs reaching over $17,400, as reported by the New York Post.

In Sands Point, the jewel of Nassau County's affluent enclave, the cost of living soars, homes fetch for an eye-watering average price of almost $3 million based on information gathered from CBS News New York, Old Westbury and Muttontown, not too distant in extravagance, fill the second and third spots with their own hefty price tags for daily living requirements. Suffolk County's claim to affluent fame, namely the Hamptons, trails behind with Southampton and Montauk ranking but not exceeding their Nassau County rivals.

Westchester County, often associated with luxury, still makes its presence felt, Larchmont was found to be the county's costliest suburb and ranked eighth overall whereas Bronxville, Armonk, Chappaqua, and Pelham also featured in the top twenty, places where expenditures on essentials each month exceed $9,000. The high cost of living in these affluent suburbs highlighted by the study can be seen as both a testament to the area's desirability and a challenge for those looking to plant roots in New York's storied neighborhoods.

The New York Post lead with the story on Sands Point solidifying its position as New York's most expensive town for living costs which perhaps may not come as a shock given its historical links to the "Great Gatsby" and its sustained reputation for exclusivity; further down the list, locations like Cold Spring Harbor and Roslyn from Long Island, and several more from Westchester continue the dance between affluence and accessibility, providing a clear picture of where the Empire State's wealthiest pockets sit snugly along its storied shores.
