Overview of 400 East 17th Street

400 East 17th Street is a seven story, 81 unit post-war co-op built in 1962, just off Cortelyou Road in Ditmas Park. Unit 102 departs from the building’s conventional apartment arrangement with a maisonette layout and separate street entrance.

Apartments tend toward broad, flexible plans with large living and dining areas, entry foyers, generous bedrooms, and substantial closet space. Hardwood floors, pass through kitchens, and eastern or western exposures recur, while several residences extend to private terraces. The building has a part time doorman, live-in superintendent, ground floor laundry room, package room, bike storage, video intercom, and a full service garage with a waitlist. Cats are permitted, but dogs are not.

Cortelyou Road is less than a block away, with the Flatbush Food Co-op, cafés, restaurants, the public library, and a year round Sunday farmers market nearby. The Q train stops at Cortelyou Road about two blocks from the building, while the B and Q trains serve Newkirk Plaza farther south. Prospect Park and the Parade Ground are to the north.

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.
