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.

Full closing history with price-per-square-foot over time, the complete retrade record, and every line that has traded.

Sales sourced from NYC Department of Finance recorded transfers (BBL 1-01448-0017) and verified listing data. Apartment-level facts (line, condition, asking-price context) curated and cross-verified by The Roebling Team research desk. Not all transactions cross-verify with ACRIS records — sponsor and LLC purchases sometimes record at stipulated values rather than market price; square footage on co-ops is not officially recorded, figures shown are approximate.

What to know if you’re buying

Accessible full-service co-op with flexible policies. Subletting after two years, co-purchasing, and pieds-à-terre are accommodated — a practical profile for first-time co-op buyers and families. Confirm current terms in writing.

The amenity set is complete. Garage, roof deck, garden, and storage are real, though garage and storage carry wait lists.

Benchmark per room. Compare price per room and maintenance against other Lenox Hill co-ops, and account for the 1.5% flip tax on resale.

Confirm board requirements. Financing limits and sublet terms are board-set; verify at offer stage.

What to know if you’re selling

Market the flexibility and amenities. Sublet flexibility, the garage, and the roof deck distinguish the building in its price tier — foreground them.

Account for the flip tax. The 1.5% flip tax affects net proceeds; model it into pricing strategy.

Expect a broad buyer pool. Accessible pricing and flexible policies draw first-time co-op buyers, families, and longer-horizon owners.
