1170 Fifth Avenue

Sixty apartments across sixteen floors is roughly four per floor, and the Carpenter idiom shows in the resulting plans: entry galleries that organize the apartment rather than dumping arrivals into a living room, entertaining rooms scaled for the avenue, ceiling heights well above modern construction, and back-of-house corridors that most postwar buildings do not have. The Fifth Avenue line looks west over Central Park at the reservoir's northern end; the East 98th Street line looks south and east across the block.

Combinations have occurred here, as in every prewar house of this vintage, which is the likeliest explanation for the small spread between the Department of Finance count of 60 and the 61 that circulates in market summaries. Buyers should treat the recorded count as the record and confirm the present configuration with the managing agent. Because the building is landmarked, window replacement, through-wall air conditioning sleeves and any exterior-visible alteration are Landmarks matters as well as board matters — a distinction that materially lengthens renovation timelines and is worth raising with an architect before contract, not after.

The building runs as a full-service prewar cooperative: full-time doorman coverage, a live-in resident manager, a fitness room, a bicycle room, private storage and video surveillance in the common areas, per management-sourced records. It is not an amenity building in the new-development sense, and it should not be underwritten as one.

Because no audited financial statement or board communication for this cooperative was located in either document library, the building's capital posture — reserve position, underlying mortgage terms and maturity, assessment history, and façade and Local Law 11 cycle status — is not documented here and cannot responsibly be characterized. A buyer's attorney should obtain the last two years of financial statements, the current budget, the last two years of board minutes, and the current Local Law 11 filing status directly from the managing agent. In a landmarked prewar building on a corner exposure, the façade cycle is the line item most likely to drive an assessment, and it is the one to ask about first.

Ownership form: Cooperative. You are buying shares in 1170 Fifth Avenue Corporation together with a proprietary lease, not real property. Recorded transfers on this lot carry the ACRIS property type SP, single residential cooperative unit, which is the public confirmation of that structure.

Board approval: Purchases require a full board package and an interview. The building publishes no financial admission thresholds — no cooperative does — and the operative standards live with the board and the managing agent.

Financing: Maximum 50 percent financing, meaning a minimum 50 percent down payment, per management-sourced records. This is the most consequential single policy on the page. It removes a large share of the buyer pool at any given price and it sets a hard floor under the equity a purchaser must bring.

Post-closing liquidity: Not published. Boards at this financing posture customarily expect meaningful liquid assets remaining after closing, but the specific expectation at this building is not a matter of public record. It must be established with the managing agent before an offer is made, not discovered in the package.

Flip tax: Paid by the seller — 2 percent of the gross sale price at three years of ownership or more, 3 percent under three years, per management-sourced records. The step is unusual and it is worth timing a sale around.

Subletting: Restrictive, and inconsistently described in the sources available to us — see the note above. Short-term rentals and platform rentals are not permitted.

Pied-à-terre and secondary residence: Permitted on a case-by-case basis per management-sourced records.

Entities and non-natural purchasers: Trust purchases and trust transfers are considered case by case. Corporate purchases and leases, and diplomatic purchases and leases, are not permitted.

Co-purchase, guarantors and parents purchasing for a child: Considered case by case.

Pets: Permitted with approval. In-unit washer/dryer: permitted. Smoking: within the apartment only, not in common areas.

Transaction fees: Management-sourced records carry a buyer application processing fee of $600, background and credit-check fees per applicant and occupant, a messenger fee, and a recognition-agreement fee where the purchaser is financing; on the seller side, a managing agent transfer fee of $900 where the shareholder is an individual and $1,000 where the shareholder is an estate, plus the New York State stock transfer stamp tax of $0.05 per share. A sublet application carries its own processing fee. Confirm the current schedule with the managing agent — fee schedules change without notice.

Application timing: Management-sourced records for this building now reflect New York City's 2026 cooperative board-application law, which sets deadlines for acknowledging a completed application and for issuing a decision, and adds a registered-mail acknowledgment fee at submission. Ask counsel how the timelines apply to your contract's outside date.

Recent sales

Recent transfers at this building, curated by The Roebling Team research desk. 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. $/sf is measured on the latest sales with reliable square footage (2022): a median $3,116/sf across 1 sale. The building has traded as recently as 2026. Median listing discount 4.0% 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 1-01604-0001) 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.

Underwrite 50 percent down before anything else. The financing ceiling is the gating fact. It determines what you can offer, and it means your competition is other all-cash and half-cash buyers rather than the broader Manhattan pool.

Get the liquidity expectation before you bid. Post-closing liquidity is unpublished here, as it is everywhere. Have your agent establish the board's working expectation with the managing agent, then build the package to clear it — run the Co-op Board Qualification Calculator against the actual numbers rather than a rule of thumb.

Treat this as a primary-residence building. A pied-à-terre is possible case by case; a rental strategy is not. If the purchase depends on sublet income at any point, resolve the sublet policy in writing with the managing agent before you sign.

Corporate and diplomatic purchasers should stop here. Management-sourced records show both are not permitted. Trust structures are possible but discretionary, and the trust documents belong in the package from the start.

Landmarks review is part of your renovation timeline. The lot is inside the Expanded Carnegie Hill Historic District. Exterior-visible work requires LPC approval on top of board approval and Department of Buildings permits. Price and schedule accordingly.

Walk the block at 7 a.m. and again at 9 p.m. The rest of the block is a working hospital campus. For some buyers that is a non-issue and a permanent guarantee against a competing tower; for others it is decisive. It is not something a floor plan will tell you.

Ask for the financials and the façade cycle. No financial statements for this cooperative are on file with us. The reserve position, underlying mortgage maturity, assessment history and Local Law 11 status all need to come from the managing agent through your attorney.

Market to the buyer who can actually close. At 50 percent maximum financing, the addressable pool is narrower than your price band suggests. Positioning and outreach should be built around that reality rather than around volume.

Time the flip tax. The seller-paid transfer fee steps from 3 percent to 2 percent of gross sale price at three years of ownership. If you are approaching that date, the arithmetic is worth running before you list.

Lead with the architect and the park, and be straight about the block. Carpenter authorship and Central Park frontage are the assets. The hospital block is discoverable in five minutes and better addressed by you than by a buyer's broker in the eleventh hour.

Have the package materials ready before you accept. Prewar boards move at the pace of the least prepared party. Assemble the financial statements, house rules, alteration history and Landmarks-relevant documentation up front — it shortens the contract-to-closing window materially.

Price against upper Fifth, not against Museum Mile. The right comparable set is the Carnegie Hill cooperative inventory north of 96th Street. Run the Seller Closing Cost Calculator with the flip tax included before you set a net-proceeds expectation.
