23 West 73rd Street (The Park Royal)

The residential-hotel origin shapes the apartments: the building's roughly 232 residences run from studios through one-, two-, three-, and four-bedroom layouts and penthouse units, several with terraces, in a wide spread of configurations from the hotel-era plan. The better apartments pair high beamed ceilings and pre-war detail with renovated kitchens and baths; washer/dryers are permitted, which is a meaningful flexibility in a pre-war building. Co-op apartments here are best understood by room count and configuration; exposure, ceiling height, terrace access, and condition drive the premium structure.

Pre-war cooperative with a fuller-than-typical amenity program: 24-hour doorman and concierge, an off-lobby fitness club, a children's playroom, a laundry room, a bicycle room, and storage. As a cooperative, the building is shareholder-controlled and purchases are subject to board approval, but the policy stack is relatively flexible — 80 percent financing per building reporting, subletting permitted under policy, and washer/dryers allowed. The building's documentation is held in The Roebling Research Library and available to clients during diligence.

The flexibility is the advantage. Financing to 80 percent per building reporting, subletting under policy, washer/dryers permitted, and a pet-friendly stance toward both dogs and cats — a materially wider set of possibilities than many Central Park West–adjacent co-ops. Confirm the current board financing limit, sublet terms, and any pied-à-terre policy at offer stage.

Buy the ceilings and the layout. The residential-hotel origin produced high beamed ceilings and a wide range of configurations; evaluate each apartment on its specific plan and ceiling height, which vary across the building.

Underwrite the pre-war systems. A 1926 building requires diligence on the capital plan, assessment history, and financials. Have your attorney review the co-op's financial statements and reserve position.

The block and address are the value. A historic-district block a block from the Dakota and Central Park is the headline; weigh the co-op mechanics against the location.

Run the carry. Co-op maintenance bundles differently than condo charges plus taxes. Use the True Monthly Carrying Cost Calculator and the Co-op Affordability Calculator on the specific unit.

Lead with the flexible rules. Most buyers — and many agents — do not expect 80 percent financing, sublets, and pet-friendly rules on a Central Park West–adjacent pre-war co-op. Name the framework; it widens the buyer pool meaningfully.

Sell the ceilings and the block. High beamed ceilings, the historic-district address, the Dakota and Central Park as neighbors — these are the marketing headlines. Use them with precision.

Anchor to room-count comparables. Co-op pricing runs on rooms and configuration; same-room-count, same-exposure comparables are the right anchor, and we maintain them in the Research Library.

Mind the mansion-tax thresholds. Larger apartments here trade across the $1 million and $2 million cliffs. Run the Mansion Tax Calculator at the intended ask.

The Roebling Team at Compass works the Upper West Side and the Central Park West–adjacent blocks as a core practice area. We publish this building profile because Park Royal buyers and sellers deserve building-specific intelligence — co-op mechanics, pre-war character, and room-count comparables — not generic neighborhood commentary.
