Trafalgar House (120 East 90th Street)

The building rises fifteen stories per city records, on a lot roughly 80 feet wide, with about 81,000 square feet of building area of which roughly 71,000 is residential and 10,000 commercial. It reads as a period white-brick apartment house: consistent fenestration, protruding air-conditioner sleeves, sidewalk landscaping at a canopied entrance, two elevators serving the residential floors.

The 104 residences as originally offered ran the postwar range from studios and one-bedrooms through larger family layouts. A meaningful number have been combined since conversion — Department of Buildings alteration filings record combinations on the eleventh and fifteenth floors among others, which is why PLUTO's current count of 102 residential units sits below the 104 in the offering plan. Buyers should expect a wider spread of layouts than the original plan implies, and should treat the floor plan of any specific unit as the governing document rather than reasoning from the line letter.

Because this is a condominium, pricing is a square-footage exercise. Normalize for floor, exposure — the building's north and south exposures behave very differently on a mid-block lot between Park and Lexington — and the extent of renovation, which varies widely across a forty-year ownership history.

Trafalgar House's financial position is unusually legible from the audited statements on file, and it is the most useful thing a prospective buyer can read.

The building has funded a major capital cycle. In 2021 the board imposed a capital assessment of $4.5 million to fund replacement of the building's HVAC risers, Local Law 11 façade restoration, and roof repairs, with a discount for owners who paid in full. A separate assessment of roughly $328,000 for electric panel replacement ran alongside it. The riser replacement was contracted in June 2021 at roughly $3.19 million; through the end of 2023 approximately $3.10 million of that had been spent, leaving a small remainder. New chillers were contracted in 2024. In practical terms, the two largest deferred-capital items a postwar building of this vintage faces — mechanical distribution and façade — were funded by the current owner base; confirm completion and current condition in recent engineering reports and board materials.

Confirm the current reserve plan. The audited statements reviewed for this profile report that the governing documents did not require funds to be accumulated for future major repairs and that no reserve study or funding plan had been adopted as of those statements; identify their fiscal year and obtain later statements and board materials before treating this as current. Reserve balances at the most recent year-end on file sat under $600,000. The board's stated mechanism for future capital needs is to raise common charges, levy a special assessment, or defer the work. The 2021 assessment documents that project’s funding; it does not establish how future work will be funded. Confirm the current reserve balance and capital plan with management.

Operating assessments have been used for insurance. In both of the two most recent years on file the board imposed operating assessments specifically to offset increases in insurance premiums, and in 2023 a fuel surcharge was levied and then converted into a reserve-building assessment. Anyone underwriting the monthly carry should ask for the current common charge and the current assessment schedule, because the two have not been the same number in recent years.

Review the dated collections record. The audited statements reviewed for this profile describe retained counsel, liens and foreclosure proceedings to recover unpaid common charges and assessments; identify the years covered and obtain current aging and litigation information. The allowances for uncollectible amounts fell sharply between the two most recent years on file, and the condominium's equity position moved from a deficit to a small positive at the most recent year-end; those historical changes do not establish the current collections position or financial trend.

There is pending litigation. A complaint filed in 2009 by two unit owners against the condominium, members of its board and its managing agent, arising from a unit renovation and alleging discriminatory treatment, remains unresolved. The court denied the plaintiffs' request for injunctive relief and dismissed two causes of action early on; the condominium's motion for partial summary judgment was denied in 2023, and the matter was expected to proceed toward trial absent settlement. The defense is being funded by the directors and officers liability carrier subject to a reservation of rights, and no provision for liability has been recorded. This is disclosed in the audited financial statements and a buyer's attorney will see it in diligence; it is noted here so it is not a surprise.

Transfer fee: The lesser of one percent of the gross purchase price or the profit on the sale, payable by the incoming unit owner at closing. That "lesser of" formulation is favorable relative to a flat percentage flip tax and is worth modeling correctly.

Sublet fee: Two months of the then-current common charges, charged annually for as long as the unit is rented. Subletting is permitted, but this is a real cost and it materially changes the math for an investor buyer.

Move-in and move-out fees apply, as do storage fees for building storage.

Pets: Reported not permitted in listing records. Confirm the house rules directly — this is the single policy most likely to disqualify a buyer here, and it is the one most worth verifying rather than assuming.

Board process: As a condominium, the board exercises a right of first refusal on transfers rather than approving purchasers. The purchase package is lighter than a cooperative's, and financing is a conventional mortgage on real property.

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 (2026 to date) cleared a median $1,130/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 3.1% 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 1-01518-7501; 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.

Ask for the current assessment schedule, not just the common charge. Between the 2021 capital assessment, the insurance operating assessments, and the 2023 fuel-and-reserve assessment, the headline common charge has understated the true monthly for several years running.

Confirm the pet policy in writing. Listing records report that pets are not permitted. If that is a threshold issue, resolve it before you spend money on diligence.

Read the litigation note in the current financials. It has been in the statements since 2009. Your attorney will want the current status.

Model the transfer fee correctly. It is the lesser of one percent of price or the profit on the sale — which for a seller in a flat market can be considerably less than one percent.

Verify the unit's actual configuration. With combinations recorded across multiple floors, the line letter is not a reliable guide to layout or size.

Lead with the capital story. The risers, façade and roof were paid for by the current owners; have completion records and current condition documented. In a postwar Carnegie Hill condominium, that is the argument, and it is worth more than an amenity list.

Be ready on the assessment and litigation disclosures. Both are in the audited statements a buyer's attorney will read. Getting ahead of them is far better than being asked.

Price against the neighborhood's condominium supply, not its cooperative supply. The competitive set for a Carnegie Hill condominium buyer is small, and that scarcity is the building's pricing advantage.
