421 Second Avenue (Tracy Towers)

The 162 cooperative apartments are distributed across sixteen floors, with a unit mix weighted toward studios and one-bedrooms and a smaller complement of larger layouts, including penthouse apartments at the top of the tower. Rothman's plan is efficient rather than grand: functional room proportions, generous window lines for the era, and a compact core that supports the building's high unit count.

The mid-century white-brick facade is the corridor's period vernacular — the same postwar apartment-house language found across Second and Third Avenues in Kips Bay and lower Gramercy. Higher floors benefit from open exposures and skyline views; the landscaped rooftop terrace captures Empire State Building and open-sky sight lines that are a genuine amenity for a building at this price point.

View permanence is reasonable for the location. The surrounding blocks are substantially built out with mid-rise and tower product, and the building's height relative to its immediate neighbors preserves light and air on the upper floors better than the lower ones. As with any co-op of this vintage, apartment condition varies widely — renovated units and original-condition units trade at meaningfully different prices per room.

421 Second Avenue operates as a full-service cooperative with a 24-hour doorman, a live-in resident manager, central laundry, bike and private storage, on-site parking, and the broader amenity package noted above — rooftop terrace, fitness center, residents' lounge, and children's playroom. For a building of its size and era, the service level is strong.

Carrying cost is the story shareholders should understand first. As a co-op, the monthly maintenance charge bundles the building's underlying operating costs, property taxes, staff, and any underlying mortgage into a single figure, a portion of which is tax-deductible (the building's deductibility figure has historically run in the range of half of maintenance — confirm the current percentage during due diligence). Maintenance on a studio or one-bedroom has historically run in the low four figures per month, which is the building's core value proposition: full doorman service and amenities at a monthly carry well below comparable condominium alternatives.

Buyers should review the building's most recent financial statements, reserve levels, board minutes, and any assessment history during due diligence. The 1982 renovation and the age of the building mean capital planning — facade, elevators, mechanicals, and roof — is an ongoing reality; a healthy reserve and a disciplined board are what separate a well-run mid-century co-op from a problem one.

Recent sales

Recent transfers at this building, curated by The Roebling Team research desk. Apartment-level facts are independently verified before publishing; sale prices reflect the recorded transfer amount at the NYC Department of Finance.

Market read. Most recent trades (2026) cleared a median $1,291/sf across 1 sale. Median listing discount 2.9% 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 1-00905-0026) 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.

This is a true cooperative — plan for the board process. An accepted offer begins a full board-package application: financial disclosure, references, and a board interview. Underwriting focuses on whether a purchaser can comfortably carry and maintain the apartment. Guarantors, co-purchasing, and parents purchasing for children are permitted with board approval — flexibility that widens the buyer pool relative to stricter Gramercy co-ops.

Model the maintenance, not just the price. In a co-op, monthly maintenance — not price per square foot — is the number that governs affordability and resale. A portion is tax-deductible; confirm the current deductibility percentage, the maintenance level, and any recent or pending assessment during due diligence.

Understand the financing and down-payment limits. The building permits financing to a defined maximum, with a minimum down payment in the range typical of mid-market Manhattan co-ops (historically around 25% — confirm the current requirement). Buyers financing to the maximum should confirm both the building's ceiling and their lender's co-op approval before signing.

Confirm the flip tax and closing math. The cooperative carries a transfer fee (flip tax); the structure and who pays it affect both buyer and seller math. Run your numbers through the Buyer Closing Cost Calculator, and note that a co-op purchase is not subject to title insurance the way a condo is, which changes the closing-cost profile.

Mansion tax rarely applies here. At the building's typical price points, purchases fall well below the $1,000,000 mansion-tax threshold — but if you are buying a larger or combined unit, run the price through the Mansion Tax Calculator to confirm.

Pied-à-terre and sublet flexibility is real but conditional. Pieds-à-terre are permitted with board approval, and subletting is allowed after two years of owner-occupancy subject to board sign-off. Investment-oriented buyers should confirm the current sublet policy and any sublet fees in writing before relying on rental income.

Price to the room and to the maintenance. Buyers at this price point are comparing monthly carry as much as sticker price. Positioning your apartment against the building's studio and one-bedroom comps — adjusted for floor, view, condition, and maintenance — is what drives a clean sale.

Condition sells the premium. Renovated, turn-key apartments clear at a clear premium over original-condition units. If your apartment is renovated, the marketing should make that the headline; if it is original, price should reflect the buyer's renovation budget.

Prepare the buyer for the board. The deepest buyer pool for this building is first-time purchasers who may not know the co-op process. A well-prepared board package and realistic expectation-setting on the interview timeline reduce fall-through risk.

Closing timelines run on co-op time. Board application, review, and interview add weeks that a condo sale does not carry. Build that into your timeline and your buyer's expectations from the start.
