In the 1980s and early 1990s, Manhattan’s Upper West Side still had many modest prewar co-ops relative to today’s market. Sales records from the mid 1990s show classic wood-floored two-bedroom co-ops in prewar doorman buildings on the UWS selling in the mid-$300,000s to a little under $500,000—prices that seem shockingly modest now.

During the 1990s through the early 2000s, NYC’s broader real estate boom impacted the UWS as well. By the late 1990s, those same prewar two-bedroom co-ops were regularly selling above $400,000 to $600,000. Through the 2000s, rising demand for classic Manhattan apartments—combined with limited new construction on much of the neighborhood’s older blocks—continued pushing values upward. A 2010 market report from appraisal firm Miller Samuel showed median co-op prices on the UWS closer to $800,000 to $830,000, with more and more crossing the $1 million threshold. 

By the 2010s and into the 2020s, typical prewar co-ops on the Upper West Side were fixed firmly in the seven-figure range. Douglas Elliman reports from the early 2020s show median sales prices for UWS co-ops near $900,000, with average prices well over $1.3 million.

As of 2024–2025, market data indicates the median sale price for these co-ops remains around $900,000 to $1.3 million depending on size and location, sometimes with prices per square-foot in more desirable parts of the neighborhood exceeding $1,200-$1,300 in more desirable areas.
