535 West 110th Street

Fourteen stories and a penthouse across a 175-foot frontage produce large, conventionally planned pre-war apartments with real bones. The published layouts run from studios in the G line with an eight-foot entry foyer and a windowed kitchen, through one-bedrooms in the A line with twenty-foot living rooms, to two-bedrooms in the H line laid out the way 1920s buildings laid them out — a long entry foyer or gallery opening onto a nineteen-foot living room, a separate nineteen-foot dining room, and a nineteen-foot windowed kitchen beside it. Ceilings are high in parts of the building and eat-in kitchens are common. The penthouse level carries private terraces, including one of roughly 590 square feet.

The combination history in the Department of Buildings record is worth reading before you shop. Apartments 8B and 8D were combined in 2015, 11C and 11E in 2022, penthouses 1 and 2 in 2008, and 8C and 9C were joined vertically in 2005 with a new opening cut through the structural slab and a convenience stair. This is a building where the board approves ambitious alteration work, including structural work — which is both an opportunity and a reason to read the alteration agreement carefully. Note also that the two large roof decks are a common amenity, and that some apartments carry protruding through-wall air-conditioners that are now subject to LPC review when replaced.

Full-service and traditional: an attended lobby around the clock, a live-in resident manager with a full staff, a central laundry, a bicycle room, cold storage, private storage available for a fee, and a fitness room that has been renovated and is offered on a membership basis. In-apartment washer-dryers are permitted with board approval, which is unusual for a building of this age and is documented in individual DOB filings rather than in any published policy.

On the tax side there is nothing to model and that itself is the finding. The building carries no J-51 exemption, no J-51 abatement, and no other property-tax benefit on the New York City Department of Finance exemption roll for fiscal years 2021 through 2027. Whatever J-51 benefit may have attached to the alteration work PLUTO records in 1986 and 2005 has fully expired; there is no burn-off ahead and no schedule to price. PLUTO shows a small residual exempt total on the lot with no corresponding record in the exemption detail, which is a reporting artifact rather than a benefit.

Underlying debt has been managed steadily rather than aggressively. The apartment corporation took an $8,000,000 mortgage at the 2004 conversion, refinanced and consolidated in November 2012 alongside a separate multi-million-dollar credit facility, and modified again in February 2019 with a further facility recorded that October — leaving underlying debt in the range of $8 million with a credit line behind it. Those are recorded instruments, not audited balances; the current outstanding principal, the rate and the maturity are in the building's financial statements and should be obtained from the managing agent.

The public record dates the cooperative conversion precisely. On October 4, 2004, a deed conveying the building to Cathedral Parkway Apartments Corp. was recorded in ACRIS, together with the corporation's original $8,000,000 mortgage and seventy-two individual share transfers closing the same day — the insider closings. Share transfers have continued in every year since, to separately named purchasers, but those names do not establish beneficial relationships or present common control.

It is a young conversion, and that has consequences a buyer should raise directly with the managing agent:

• Sponsor concentration. Listing records describe the building as roughly 85 percent sold. If a sponsor or holder of unsold shares still owns a meaningful block, some lenders will treat that as an underwriting item, and in a small number of cases as a decline. Ask for the current sponsor-owned percentage in writing.
• Non-purchasing tenants. A 2004 conversion can leave rent-regulated non-purchasing tenants in place for decades. The number, if any, is not in the public record. Ask.
• Reserve depth. A twenty-two-year-old cooperative in a hundred-and-three-year-old building that has just completed a major façade program has a specific reserve question in front of it. The financial statements will answer it; nothing public will.

Board package and interview. Standard for a Manhattan cooperative: a full financial package, references, and an in-person interview. Run the Co-op Board Qualification Calculator before offering.

Financing. Up to 80 percent per listing records — permissive, and a real advantage over the neighborhood's older conversions, which commonly cap at 75 percent. Verify with the managing agent.

Post-closing liquidity. Not published. Obtain the board's current standard before you bid; in a building of this size it is the requirement most likely to decide a marginal file.

Subletting. Permitted after two years of residency with board approval. Maximum term, renewal policy and the sublet fee are not published — get all three from the managing agent.

Pied-à-terre. Permitted case-by-case with board approval, per listing records. Confirm; pied-à-terre postures shift with board composition.

Trusts, LLCs and guarantors. Not addressed in any public record. Assume board discretion and get the answer in writing before contract.

Flip tax. Not published. Assume one exists and confirm the amount and the payer.

Landmark compliance. Exterior work, window replacement, through-wall air-conditioner replacement and any interior work requiring a DOB permit runs through the Landmarks Preservation Commission as well as the Department of Buildings. Build the extra review time into any renovation schedule.

Recent sales

Recent transfers 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 (2026 to date) cleared a median $972/sf (floor-adjusted) across 3 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 2.0% 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 1-01882-0008). 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 on co-ops is not officially recorded, figures shown are approximate.

Underwrite the façade cycle first. The Cycle 9 record ran UNSAFE from February 2024 through at least November 2025, with an amended report reporting SAFE in August 2026. Ask your attorney for the last five years of board minutes, every assessment resolution, and the engineer's final report. A completed façade program is a good thing to buy into — but only once you know what it cost and whether it was funded from reserves, an assessment, or the credit line.

Confirm the landmark reality before you plan a renovation. You are inside the Morningside Heights Historic District. Your neighbor at 545 is not. Window replacement, louvers, wall sleeves and any permitted interior work require LPC sign-off in addition to DOB.

Ask three questions about the 2004 conversion. Current sponsor-owned share percentage; number of remaining non-purchasing tenants; reserve balance. All three affect financeability and none of them are public.

Test the 80 percent ceiling. If it holds, this building is materially more accessible than most pre-war co-ops in Morningside Heights. Get it confirmed in writing rather than from a listing.

Walk the block twice. Cathedral Parkway carries crosstown traffic and the 1 train is at the corner of Broadway. Rear and interior lines are quiet; front lines are not.

Lead with the finished façade, not around it. A completed Local Law 11 program with a SAFE report on file is a selling point. Buyers' attorneys will find the UNSAFE history regardless; you want to be the one who framed it.

Say "80 percent financing" early. State the documented limit and confirm its current application; it does not establish a measurable buyer-pool advantage over other listing decisions.

Document what LPC has already approved in your apartment. A Certificate of No Effect on file for work already done removes a category of buyer anxiety and is worth putting in the package.

Pre-war layout is the product. Separate dining rooms, windowed kitchens, long galleries and high ceilings are features to compare with the actual plans of neighboring alternatives. Market against the neighborhood's new construction on plan, not on finish.
