Just Listed!!! Meticulously maintained and immaculately kept 2-bedroom 1 bath with partial seasonal view of the National Cathedral. Don't miss this sneak peek open! Call agents with any questions! Updates will be available; coming soon! Please join us at our open house on Saturday, June 7th from 1-3 pm. Situated on nearly 10 acres, the Westchester Coop was built during the Great Depression & completed in 1931. As noted in many publications it has extraordinary Art Deco classic features. You will be mesmerized by its charm of yesteryear and memories influenced by the roaring twenties, such as its metal-etched elevator doors, elegant archways, and plastered moldings. Notice the beautifully manicured grounds, gardens, brick and stone walkways, a center sunken fountain, and a porte cochere in front of the main building. The unit has 9-foot ceilings, parquet floors, and lots of natural light. The Westchester boasts great amenities, including a market grocery store, a beauty parlor, a fitness center, dry cleaning services, and the wonderful DeCarlo's Restaurant, where you can enjoy weekend valet service between the north and south main buildings. All of the buildings at 4000 Cathedral Ave. are connected by ground-floor hallways, making it super convenient to get around, no matter the weather. Plus, there's an underground reserved parking garage, extra storage options, and guest rooms available for friends and family visiting you! For coop mortgage approval, you'll need a minimum of 15% down, and we can provide a list of approved lenders if you need it. Feel free to reach out to the listing agent with any questions you may have or to set up a time on Showingtime or agent for access through the OB lobby front desk.

As a licensed real estate brokerage, Estately has access to the same database professional Realtors use: the Multiple Listing Service (or MLS). That means we can display all the properties listed by other member brokerages of the local Association of Realtors—unless the seller has requested that the listing not be published or marketed online.
The MLS is widely considered to be the most authoritative, up-to-date, accurate, and complete source of real estate for-sale in the USA.
Estately updates this data as quickly as possible and shares as much information with our users as allowed by local rules. Estately can also email you updates when new homes come on the market that match your search, change price, or go under contract.
