A Private Pricing Opinion — what your apartment at 144 East 84th Street 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.
144 East 84th Street is a solid, primary-residence Upper East Side cooperative on the corner of Lexington and 84th, at the edge of Carnegie Hill. Built in 1963 and converted to cooperative ownership in 1971, it is a well-run doorman building with a furnished rooftop terrace and — notably — no flip tax, at a price point below the prime Upper East Side avenues. It is the kind of building that anchors the neighborhood's owner-occupier residential base.
For buyers, the building's appeal is straightforward: a full-time-doorman cooperative in a convenient Upper East Side location, with a genuine outdoor amenity in the furnished roof terrace, and without the transfer-tax cost that most neighborhood co-ops impose. The corner-of-Lexington location places residents steps from the 4/5/6 trains at 86th Street, from Lexington and Third Avenue retail, and — for family buyers — near the Carnegie Hill private-school cluster covered in our Upper East Side corridor guide.
The tradeoff is that the building is oriented toward primary residents rather than investors or part-time owners: pied-à-terre use is not permitted, and subletting requires board approval. That orientation keeps the resident base owner-occupied and stable, which many buyers value. Like most Upper East Side cooperatives, the building prices in rooms rather than square feet.
Building operations
144 East 84th Street operates as a full-service cooperative with a 24-hour doorman, a live-in super, a central laundry, a bike room, common storage, and a furnished rooftop terrace. There is no garage and no fitness center — this is a service-and-location building with a roof amenity rather than a full amenity tower.
As a cooperative, the building reviews prospective purchasers through a board application and interview process. There is no flip tax, financing is permitted up to 70% (30% down), and subletting is permitted with board approval. Pied-à-terre use is not permitted — the building is oriented toward primary residents. Specific current policies, including pet policy detail, should be confirmed against building materials and the managing agent during due diligence. Our Co-op vs Condo guide covers the ownership-structure framing.
Architecture and building character
The building is a 1963 postwar red-brick cooperative — a mid-century structure characteristic of its era rather than pre-war or contemporary. It occupies the corner of Lexington Avenue and 84th Street. The roughly 15-story height gives upper floors improved light, and the furnished rooftop terrace provides the building's principal outdoor amenity.
The apartment mix reflects postwar Upper East Side construction — layouts across roughly 93 residences, priced by room, ranging from studios through larger multi-bedroom configurations.

The latest available FISP filing classified the facade as Safe — no repairs were required at that inspection. Facade inspections run on a fixed five-year cycle; future inspection, repair, and any assessment decisions remain building-specific.
How to read this, and where it comes from
QEWI = Qualified Exterior Wall Inspector — the licensed engineer the city requires to sign the report (the independent expert, not the managing agent).
Penalties shown are amounts DOB assessed against filings on record across 2005–10 to 2020–25. The FISP dataset does not record whether they were paid, contested or remain open, so treat the figure as history rather than a current balance and confirm the building’s standing with the managing agent.

Recent sales
144 East 84th trades at the Upper East Side's accessible cooperative tier, priced by room, with recent trading below the prime avenue cooperatives. The absence of a flip tax improves seller economics, and the furnished roof terrace and full-time service support demand at the tier, while the primary-residence orientation (no pied-à-terre, board-approved subletting) keeps the resident base stable. As with any cooperative, pricing should be read at the apartment level; room count, floor, exposure, and condition drive the variation.

What to know if you’re buying
This is a primary-residence cooperative — priced by room, board-approved. Expect the cooperative purchase framework: a board application, a financial review, and an interview. The building is oriented toward owner-occupiers.
There is no flip tax. Most Upper East Side cooperatives impose a transfer tax at sale; 144 East 84th does not, which improves seller economics and can factor into buyer math.
Pied-à-terre use is not permitted. Buyers who want a part-time or investment apartment should look elsewhere; this building is for primary residents.
The furnished roof terrace is the building's outdoor amenity. For a cooperative at this tier, a furnished roof deck is a genuine draw.
Model the maintenance and the underlying mortgage. As a cooperative, the monthly maintenance covers the building's operating costs, property taxes, and any underlying mortgage. Review the building's financials and reserve position.
What to know if you’re selling
Foreground the no-flip-tax policy and the roof terrace. The absence of a transfer tax and the furnished roof deck are the building's principal selling points at the accessible Upper East Side cooperative tier. Pair them with the corner-of-Lexington convenience.
Pricing requires apartment-level comparable analysis. Recent comparables on the specific line, room count, floor, and exposure should anchor the approach.
Board approvability shapes the buyer pool. The primary-residence orientation and the board review mean the buyer pool skews to owner-occupiers; prepare buyers for the application and price to attract financially qualified applicants.
Closing timelines run to the cooperative calendar. Plan for a board application and interview cycle in addition to standard closing timelines.

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.
