A Private Pricing Opinion — what your apartment at The Morad Diplomat would likely sell for today, what it costs to sell, and what you’d walk away with — reviewed personally against condition, exposures, renovation quality, and the competition actually on the market.
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.
Sublet and pied-à-terre policy
A condominium owner leasing a unit and a co-op shareholder subletting are different rules, and a building-wide rule is different from a restriction on one apartment. This is the building's rule; confirm it for the specific apartment.

Recent sales
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.

Market read. Most recent trades (2026 to date) cleared a median $976/sf (floor-adjusted) across 1 sale. Floor-adjusted means each sale is restated to a constant mix of floors, so the figure can differ from the plain median of the sales listed above. Median listing discount 2.2% from the last ask — a recurring negotiation gap worth pricing into any offer or listing strategy.

How to read the facts on this page. Items attributed to an offering plan describe the building as it was offered at that filing — unit mix, square footage, the amenity program as planned. They are not a statement about how the building operates today. Tax and compliance figures are sourced separately to current City records and carry their own dates. House rules, staffing and fee policy can change by board resolution without any public filing: treat every policy line here as a starting point for diligence and confirm it with the managing agent. Where this page compares one building or neighborhood to another, that is our analysis of the recorded record — it names the measure, the period and the sample it rests on, and it is an observation about medians rather than a prediction about any particular apartment.
