Eliza Theiss, Mar 19, 2026 Cheaper in the City? Nearly 100 Communities in Suburban NYC Surpass $1M
New Yorkers planning a move to the suburbs increasingly find their options limited, after suburban home values shot up twice as fast as NYC medians over the last decade.

Prices continued to rise across most of the 50 priciest New York City neighborhoods in 2025, with increases of up to 39% year-over-year. Hudson Yards remained the most expensive NYC neighborhood for the seventh consecutive year, despite its median sale price dropping.
