The Morad Diplomat is a practical full-service Lenox Hill cooperative built for livability and equity-building rather than trophy status. Completed in 1961 as a rental and converted to a co-op in 1985, the 13-story white-brick building holds 142 apartments between First and Second Avenues, with a 24-hour doorman and concierge, a live-in superintendent, and a notably complete amenity set — an attached parking garage, a landscaped roof deck, a common garden, and storage.
Its reputation rests on flexibility uncommon among co-ops: pieds-à-terre, co-purchasing, and parents buying for children are accommodated, and subletting is permitted after two years of ownership with board approval. Combined with accessible pricing relative to the white-glove buildings to the west, that policy posture makes the Morad Diplomat a sensible option for first-time co-op buyers, families, and buyers who want a doorman building with room to sublet down the road. A flip tax of 1.5% of the gross sale price applies.
The location between First and Second Avenues on 73rd Street places residents near the Second Avenue subway (Q) and the 6 train, the Lenox Hill retail grid, and an easy walk to the East River esplanade.
Architecture and unit composition
The 142 residences span a 13-story postwar elevator building, with a practical layout mix and private balconies on some lines. The white-brick exterior and efficient floor plates are characteristic of the early-1960s vintage; the marble lobby and renovated common spaces reflect the building's full-service positioning. The landscaped roof deck and common garden are meaningful shared outdoor amenities.
Building operations
The Morad Diplomat operates as a full-service co-op with a 24-hour doorman and concierge and a live-in superintendent. Amenities include an attached on-site parking garage (with a wait list), bike storage, a resident storage room (wait list), the landscaped roof deck, a common garden, and central laundry. The 142-unit scale spreads operating costs across a substantial owner base. Buyers should review the co-op's financial statements, reserve fund, and any assessment history, and confirm the current sublet, financing, pied-à-terre, and flip-tax terms in writing during due diligence.

As a cooperative, 345 East 73rd Street is benchmarked on a price-per-room basis with monthly maintenance in context. The building trades at accessible price points relative to the white-glove co-ops of the central Upper East Side, and its flexible policies — sublet after two years, co-purchasing, parents buying for children, pieds-à-terre — broaden the buyer pool. Pricing varies by line, floor, balcony, and exposure, with upper-floor and balconied units commanding the premium. The 1.5% flip tax should be factored into seller net-proceeds analysis. Specific financing, sublet, and flip-tax terms should be confirmed at offer stage.
