148 East 84th Street is a 1930 prewar cooperative on a quiet Upper East Side cross street between Lexington and Third Avenues — a small, five-story elevator building of seventeen apartments, roughly four to a floor. It is the kind of intimate prewar co-op that forms the residential backbone of the Upper East Side: modest in scale, well-kept, and priced for buyers who want prewar bones and a well-run building rather than a full amenity package. The address places residents a short walk from Central Park and Museum Mile to the west and the shopping and transit of the 86th Street corridor a couple of blocks north.
What buyers respond to here is the combination of prewar character, a manageable co-op, and a strong Upper East Side location at a boutique scale. With only seventeen shareholders, the building is closely held and owner-occupied in character; the co-op structure and the small shareholder base define both its stability and its pricing.
This is a cooperative, not a condominium — a distinction that shapes financing, the buyer pool, and the approval process. 148 East 84th rewards the primary-residence buyer who wants a well-located prewar home and the stewardship a small co-op provides.
Architecture and unit composition
148 East 84th Street is a straightforward, well-proportioned 1930 prewar brick apartment house — five stories, an elevator, and the kind of solid, unshowy massing typical of the Upper East Side's between-the-avenues blocks. With approximately four apartments per floor across seventeen homes, the residence mix runs to the intimate scale of a small prewar building: apartments that retain prewar proportion and, in the well-kept units, the details buyers look for in a building of this era.
The building is deliberately modest in its common footprint — an elevator, central laundry, a bicycle room, and storage — consistent with a boutique co-op that keeps carrying costs contained.
Building operations
148 East 84th Street runs as a boutique cooperative: an elevator, central laundry, a bicycle room, and common storage, without the staffing of a full-service building. As with any cooperative, the board sets financing limits, sublet policy, and any flip tax, and reviews prospective purchasers through a board-package-and-interview process; buyers should confirm the current financing cap, pied-à-terre stance, and sublet terms in writing before committing. Monthly maintenance in a seventeen-shareholder building reflects a small base carrying the building's fixed costs, so due diligence on the financials, reserves, and any assessment history matters here.

Sales sourced from NYC Department of Finance recorded transfers (BBL 1-01512-0048) 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
This is a cooperative — underwrite accordingly. Financing is capped by the board, purchases run through a board package and interview, and the building is oriented toward owner-occupants. Confirm the current financing limit and sublet policy before you commit.
It's a boutique building. Seventeen apartments and a lean amenity set mean lower carrying costs but no doorman; price the trade-off accordingly.
Expect prewar individuality. With roughly four apartments per floor and seventeen homes, layouts vary. Walk each unit on its own terms — floor, exposure, and condition all move the value.
Budget any flip tax and assessments. In a small co-op, confirm the flip tax, reserve position, and any assessment history during due diligence.
Mansion tax thresholds apply. At this building's pricing, the $1M cliff can be in play. Run pricing through the Mansion Tax Calculator.
What to know if you’re selling
Lead with the prewar character and the location. The 1930 building and the quiet, well-located block are the marketing story; foreground them.
Comp at the apartment level. With seventeen heterogeneous units, generic neighborhood averages mislead. Price from the building's own trades and the closest boutique co-op peers.
Prepare the buyer for the board. A well-prepared board package and a financially strong, primary-residence buyer move a co-op sale to closing; set expectations early.
