A Private Pricing Opinion — what your apartment at 50 Park Avenue 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.
50 Park Avenue is the architecturally most consequential Murray Hill Park Avenue cooperative and a structurally specific entry-tier building within the broader Park Avenue corridor. The 1940 commission by George Fred Pelham Jr. for developer Louis Cowan is one of three Pelham Jr. Park Avenue commissions of the late-pre-war 1939–1941 sub-era — alongside 785 Park Avenue in Lenox Hill (also 1940) and 1150 Park Avenue in Carnegie Hill (also 1940). The three buildings together represent a structurally distinct architectural-history moment within the broader Park Avenue cooperative tradition: the late-pre-war Pelham Jr. body of work that bridges the Candela / Carpenter / Schwartz & Gross 1920s boom and the post-WWII building cycle that would not resume until 1948.
50 Park's geographic position south of Grand Central distinguishes the building from the broader Park Avenue residential corridor concentrated between East 60th and East 91st Streets. The Murray Hill positioning produces a structurally specific cooperative-market identity: more accessible pricing, more permissive policy framework, and a substantially different buyer pool from the trophy pre-war Carnegie Hill and Lenox Hill cooperative tradition.
The 1972 cooperative conversion places 50 Park among the broader post-war Park Avenue rental-to-cooperative conversion wave that reshaped the corridor's ownership structure during the 1970s and 1980s. The conversion-era institutional history is structural to the building's contemporary cooperative culture.
Architecture and unit composition
The approximately 125 cooperative apartments distribute across the building's 17 stories. The unit mix skews to studios and one-bedrooms — a structurally unusual configuration for Park Avenue's white-glove stretch but consistent with Pelham Jr.'s late-pre-war Murray Hill planning approach.
Apartment-level features documented across the building's inventory carry the late-pre-war architectural fabric characteristic of the 1940 vintage: substantial ceiling heights for the era, formal entry arrangements, and the layout discipline of the late-1930s Park Avenue building cycle.
The architectural composition above the fourth-floor limestone bandcourse is deliberately unornamented — a stripped-Classical idiom structurally distinct from the more elaborate Italian Renaissance and neo-Georgian registers that defined the 1920s Park Avenue residential mainline. The architectural simplicity reflects both Pelham Jr.'s late-pre-war design vocabulary and the broader construction-economy realities of the 1939–1941 sub-era at the cusp of WWII.
Building operations
50 Park operates as a full-service cooperative with 24-hour doorman, live-in resident manager, central laundry, bike room, and basement storage lockers. The amenity infrastructure includes a rooftop garden with documented views of the Empire State Building, the Chrysler Building, Grand Central Terminal, and the broader Park Avenue corridor — a structural amenity feature meaningful to upper-floor and rooftop-access residents.
The cooperative policy framework is structurally permissive within the broader Park Avenue cooperative tier: 70 percent maximum financing (materially more accessible than the 40–50 percent typical of Carnegie Hill and Lenox Hill cooperatives), pet-friendly, pied-à-terre permitted. The combination supports a structurally specific buyer pool — first-time Manhattan cooperative buyers, family-supported buyers, pied-à-terre users, and buyers seeking Park Avenue address quality at materially more accessible price points than the surrounding pre-war trophy cooperative inventory.
Recent sales and pricing
The building's pricing positioning reflects the Murray Hill geographic context and the studio-and-one-bedroom-dominant inventory composition — materially more accessible than peer Lenox Hill or Carnegie Hill cooperative pricing, and calibrated to a buyer pool prioritizing Park Avenue address quality at entry-tier pricing. Inside the building, pricing is set configuration by configuration, with floor, exposure, and renovation condition driving the spread between apartments of the same layout.

Market read. Most recent trades (2026 to date) cleared a median $849/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 2.0% from the last ask — a recurring negotiation gap worth pricing into any offer or listing strategy.

What to know if you’re buying
The Pelham Jr. late-pre-war architectural credential is real. Among three Pelham Jr. Park Avenue commissions of the 1939–1941 sub-era; the architectural pedigree connects 50 Park to 785 Park and 1150 Park within the broader Pelham Jr. body of work.
The Murray Hill geographic positioning is structural. South of Grand Central; not within the Carnegie Hill or Lenox Hill pre-war trophy cooperative concentration; pricing reflects the corridor positioning.
The 70 percent maximum financing is unusually permissive. Materially more accessible than typical Park Avenue cooperative norms; structurally supports a broader buyer pool.
The pied-à-terre allowance is meaningful. Most Park Avenue cooperatives require primary residence; 50 Park's permissive structure supports pied-à-terre use.
The studio-and-one-bedroom-dominant inventory is structural. The right building for entry-tier buyers; the wrong building for buyers seeking the larger classic-six and classic-seven pre-war configurations characteristic of trophy Park Avenue inventory.
The rooftop garden views are real. Empire State, Chrysler, Grand Central, and the broader Park Avenue corridor are documented visible amenities.
Verify operational specifics during due diligence. Specific board approval framework, sublet duration limits, flip tax structure, current capital project pipeline, and the LL11 façade cycle on the 1940 vintage should be reviewed against current management documents.
Closing timelines are cooperative-standard. Plan for 6–10 weeks from contract through board approval to closing.
What to know if you’re selling
Marketing should emphasize the Pelham Jr. architectural credential and the permissive policy framework. Both are structural identity features that distinguish the building from peer Murray Hill cooperative inventory.
The 70 percent financing accessibility expands the buyer pool meaningfully. Marketing should reach the broader Manhattan cooperative buyer demographic that peer trophy buildings do not support.
The pied-à-terre permission is a real buyer-pool-expansion feature. Pied-à-terre buyers — institutional, international, and second-residence — should be reached specifically.
Pricing should reference recent comparable closings on the specific apartment line. The studio-and-one-bedroom-dominant inventory produces meaningful variation across apartment configurations.
Closing timelines are cooperative-standard.

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.
