Eliza Theiss, Apr 23, 2026 $4.6M Hudson Yards Maintains Top Spot, Luxury Sales in Malba Set $2.5M Price Record for Queens
Despite prices declining, Hudson Yards remained the most expensive NYC neighborhood, but TriBeCa’s growth closed the gap to under $400,000, while Malba set a new historic price record for Queens at $2.5 million, securing the highest ranking ever for the borough at #5.
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. While larger homes and better prices were long the norm outside the five boroughs, today, many NYC buyers find their option restricted to a handful of suburban markets.
