Overview of 317 East 73rd Street

317 East 73rd Street is a classic brownstone and brick prewar co-op building located on a tree lined block in the heart of the Upper East Side. The walkup building features a collection of one bedroom, one bathroom apartments, many of which retain charming period details including decorative fireplaces, exposed brick walls, high ceilings, and hardwood floors. Several units have been updated with renovated kitchens and bathrooms, and some include in-unit washer/dryer combos or dishwashers.

Apartment layouts vary throughout the building, with some units offering unique features like skylights, spiral staircases leading to standing lofts suitable for home offices or storage, and south facing windows that provide abundant natural light. Top floor units enjoy treetop views and particularly bright exposures. The building includes sponsor units that transfer with full sponsor rights, requiring no board approval for purchase and allowing unlimited subletting, making them attractive options for both owner occupants and investors.

The building offers flexible policies including pied-Ă -terre purchases, co-purchasers, guarantors, and pets permitted. Financing up to 80% is allowed. The location provides easy access to the Q and 6 trains, M15 and M72 buses, and the Second Avenue Subway station at 72nd Street. Residents are within walking distance of Central Park, the East River promenade, and the neighborhood's extensive dining, shopping, and nightlife options.

Sales History

Price/Room (Est)

Why are we displaying the estimated price per room?

For some co-ops, instead of price per square foot, we use an estimate of the number of rooms for each sold apartment to chart price changes over time. This is because many co-op listings do not include square footage information, and this makes it challenging to calculate accurate square-foot averages.

By displaying the price per estimated room count, we are able to provide a more reliable and consistent metric for comparing sales in the building. While we hope that this gives you a clearer sense of price trends in the building, all data should be independently verified. All data provided are only estimates and should not be used to make any purchase or sale decision.
