Overview of 523 West 143rd Street

523-527 West 143rd Street is a prewar HDFC cooperative building located in Hamilton Heights, consisting of two combined buildings with a total of 48 units. The building maintains its historic character while incorporating modern amenities, including recently restored lobby and stairwells with crown moldings, updated elevators, and a new high-tech video intercom system. Recent infrastructure improvements include a new boiler and conversion from oil to gas heating.

As an HDFC cooperative, the building operates under specific income restrictions based on 165% AMI, ranging from $179,355 for single occupants to $297,165 for households of five. The building allows financing up to 90% through Amalgamated Bank and implements a 30% flip tax based on seller's profit upon resale. The cooperative maintains a pet-friendly policy and conditional sublet allowances, though it enforces a no-smoking policy and primary residence requirement.

Individual units retain prewar architectural elements such as high ceilings (8'6" - 9'2"), original hardwood floors, and 8-foot doors with restored transoms. Many apartments feature multiple exposures with windows in all rooms, and the building's infrastructure supports modern amenities including updated plumbing and electrical systems.

Situated on a quiet, tree-lined street, the building's location offers easy access to several neighborhood amenities including the Alexander Hamilton Grange National Memorial, Riverbank Park, and Jackie Robinson Park. Transportation options include the 1 train at 145th and Broadway, the A/B/C/D express trains at 145th and Saint Nicholas Avenue, and nearby crosstown and downtown bus service.

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.
