420 Central Park West (Jadam Condominium)

The building is a six-story brick apartment house of 1941 — the tail end of the pre-war era, built to its proportions if not to its ornament. The 60 units run from studios and one-bedrooms through two-bedroom homes and combined units (several recorded combinations span adjacent lines), and the interior vocabulary in less-altered apartments is distinctly late-1930s: sunken living rooms, arched or squared gallery entries, real dining areas, and deep closets, per listing records. Renovation quality varies widely, from preserved-original units to gut renovations with open kitchens and spa bathrooms. Front-line apartments face the park directly across Central Park West; the building's modest height keeps those views at canopy level — intimate rather than panoramic, and structurally protected by the park itself.

This is a service building of deliberate simplicity: full-time doorman, elevator, live-in superintendent, central laundry, storage, and a bike room — no amenity floor, no gym, no roof deck. Common charges price accordingly. The managing agent administers a documented application process for both sales and leases; management-sourced records show modest processing-level fees, a refundable move deposit structure, and a monthly lease fee for rented units. Owners may keep up to two pets; tenants may not keep pets at all, a distinction the building enforces strictly. Lobby and capital work have proceeded in recent cycles per listing records; current assessment status should be confirmed with the managing agent during diligence.

Recent sales

Recent closings at this building, from The Roebling Research Library. Prices are the transfer amounts recorded with the NYC Department of Finance; apartment-level detail is checked against the building’s own file in The Roebling Research Library before publishing.

Market read. Most recent trades (2025) cleared a median $1,153/sf (floor-adjusted) across 2 sales. 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 1.4% from the last ask — a recurring negotiation gap worth pricing into any offer or listing strategy.

Sales sourced from NYC Department of Finance recorded transfers (BBL 1-01838-7501; each condominium apartment is its own tax lot). Apartment-level facts (line, condition, asking-price context) curated and cross-verified in The Roebling Research Library. Not all transactions cross-verify with ACRIS records — sponsor and LLC purchases sometimes record at stipulated values rather than market price; square footage from recorded condo declarations and offering plans.

The structure is the story. Pre-war, park-front, doorman, condominium — that four-way combination barely exists at this price point anywhere on the avenues bordering Central Park. If your search keeps bouncing off co-op boards or new-development pricing, this building is the structural answer.

Canopy views, not skyline views. Six stories means front units look into the park's trees, the Pool, and the North Woods at eye level. Buyers wanting horizon panoramas should look at the corridor's towers; buyers wanting green out every front window will not do better at this price.

Underwrite the leasing rules if you're an investor. Rentals are permitted with application review, a monthly building lease fee applies, and tenants may not have pets — which narrows the renter pool. The condo flexibility is real but not frictionless.

Get the offering plan and financials early. The original architect and conversion documentation are thinly documented publicly. We request the offering plan, by-laws, current financials, and assessment history from the managing agent at the start of diligence, not the end.

Know the block. West 102nd Street at the park is a different micro-market from 86th Street — quieter, more local, further from express transit (the B/C at 103rd are local stops). Spend time on the block at commute hours and price your own transit reality.

Market the scarcity, not the square footage. The buyer who needs this building — pied-à-terre purchasers, parents, first-time park-front buyers, co-op refugees — is searching by structure: pre-war condo, doorman, park view. Lead with those facts.

Park exposure is the premium; price the spread honestly. The gap between park-facing and rear or side exposures is the building's main internal pricing variable, ahead of condition. Same-line history matters more than building averages.

Anticipate diligence questions. Because public documentation on the conversion is thin, buyers' attorneys will ask for more from management. We assemble the document package early so the deal doesn't stall in attorney review.
