A Private Pricing Opinion — what your apartment at Westview would likely sell for today, what it costs to sell, and what you’d walk away with — reviewed personally against condition, exposures, renovation quality, and the competition actually on the market.
Westview is the most heavily conditioned ownership building on Roosevelt Island, and the conditions are the building. When North Town Phase III Houses was free to prepay its Mitchell-Lama mortgage and take the property to market-rate rental, the State negotiated the alternative that became the Westview Affordability Plan: a conversion to cooperative ownership in which tenants could buy at roughly 30% of market value, non-purchasers keep regulated rents, and the ground lease is extended forty years at a below-market ground rent. Tenants approved it by 92% of those voting. The plan runs thirty years.
The consequence for a buyer is that Westview contains two different products under one roof. Restricted apartments — those bought by insiders at insider prices — resell subject to a price ceiling that the State described as starting at about twice the average insider price per square foot and rising 7.5% a year; the next buyer must qualify under the Mitchell-Lama income formula (maximum income of seven or eight times the annual carrying charge, depending on household size, plus 6% of equity); and the insider's first resale pays a flip tax that begins at 60% of the gain. Market apartments — vacant units the sponsor sells at market, up to 45% of the building — trade to any buyer at any price, subject to board approval and the RIOC transfer fee, and carry a higher PILOT that phases in over ten years.
The recorded share-transfer history shows both products. More than a hundred insider closings in the fall of 2021 were recorded at a small fraction of the prices the sponsor has since achieved on renovated vacant apartments, and the three insider apartments that have resold for value since, all in the 595 building, were recorded well below sponsor market pricing and in a range consistent with the resale cap. The one arm's-length resale of a market apartment on record, in 2023, was recorded at close to its sponsor price. That is the whole open-market resale record: the building's liquidity to date has come almost entirely from the sponsor.
The third fact is control. The sponsor still holds a majority of the apartments and, per the Attorney General's record, still controls the board. Most of its apartments are occupied by renters with protected rents who may stay for the life of the plan. That is not a defect in the building, but it is the single largest variable in how Westview will govern itself, finance itself and price itself over the next decade, and a buyer's lender will ask about it.
Architecture and unit composition
Westview belongs to the first generation of Roosevelt Island housing, built by the State's Urban Development Corporation under the Johnson and Burgee master plan. Sert, Jackson & Associates designed both Westview and Eastwood, the larger rental complex to the north; the two share the architect's language of stepped, terraced brick masses. Westview's two connected buildings, addressed 595 and 625 Main Street, step to nineteen stories.
The apartment stock runs from studios upward and was sized for Mitchell-Lama occupancy rather than entertaining; confirm the current line-by-line mix against Schedule A of the offering plan. West-facing apartments look across the channel to the Upper East Side skyline; east-facing apartments look over Main Street toward Queens. Condition varies more than in any mainland conversion: renovated sponsor apartments sold since 2021 sit beside insider apartments bought in original condition and rentals that have never been renovated. The renovation gap is often the largest single variable between two otherwise similar apartments.
Building operations
Westview is a full-staff union building, with an attended lobby, a resident superintendent's apartment held by the cooperative, a pool and a fitness center. It also carries costs no mainland building has: ground rent to RIOC, a PILOT in place of a tax bill, and an annual public safety fee to RIOC for the island's public safety department, which the statements describe as escalating 3% a year. All of these are contractual and sit inside maintenance. Maintenance rose 3% effective January 1, 2024.
The capital posture on file is thin in two places. Reserve balances were under $1 million across the capital reserve, working capital and special sponsor contribution funds at December 31, 2023, after the sponsor's $6 million reserve obligation under the plan was largely satisfied by qualified capital work rather than cash. And the underlying mortgage matures on August 1, 2028 with a balance of about $24.6 million due. How the board refinances that loan, and on what terms relative to the remaining ground lease, is the most consequential near-term financial event for the building. The plan also provides a further $3.1 million special sponsor contribution once the sponsor has paid RIOC its $1.5 million transfer fee and reached $70 million in sales proceeds; sales stood at about $62 million at the end of 2023, and the threshold may since have been crossed. Ask.
Policy framework
Affordability Plan term. Thirty years. The State's 2018 announcement described the plan as in effect through 2048; the audited statements tie the affordability period, the PILOT reset and the ground rent step-change to the thirtieth anniversary of the August 1, 2020 Master Cooperative Closing, which would be 2050. Confirm the operative date in the plan.
Restricted apartments. Resale price cap escalating 7.5% a year; purchaser income limit under the Mitchell-Lama statutory formula; declining flip tax on the insider's first sale, with the first $6 million of flip-tax proceeds directed to the reserve fund and later proceeds split with the sponsor until its reserve obligation is recouped.
Market apartments. No price cap and no income limit. Board approval and the 1% RIOC transfer fee apply. PILOT phases in over ten years from the January following the Master Cooperative Closing.
Sponsor sales. Per the sponsor's purchase procedure on file, an offer requires a lender pre-approval from the sponsor's recognized-lender list if financed, a 10% down payment at contract, and payment of transfer taxes, the mansion tax where it applies, the sponsor's legal fee and a working capital contribution of two months' maintenance.
Non-purchasing tenants. Rent increases tied to the Rent Guidelines Board's one-year increase plus an income-based add-on, capped at 7.5% a year for households below 200% of area median income. The apartments are not rent-stabilized, but the protections run with the plan.
Buying here? Co-op closing costs typically run 2 to 3% of the price. See NYC co-op and condo closing costs, line by line.

What to know if you’re buying
Establish the apartment's track first. Ask for written confirmation from the managing agent and the sponsor's counsel whether the apartment is a restricted apartment or a market apartment, and if restricted, the current maximum resale price and the income limit that will apply to you and to your eventual buyer.
Underwrite the sponsor. Ask for the sponsor's current holdings, the number of apartments rented, its arrears position, and when it expects to cede board control. A sponsor-majority building can face tighter lender scrutiny; confirm with your lender before contract, not after.
Underwrite the 2028 maturity. The underlying mortgage balloons on August 1, 2028. Ask the board for its refinancing plan and whether the reserve balance has been rebuilt.
Read the ground lease and the extension. The Westview lease runs to December 22, 2068. Have counsel confirm whether the ten-year master lease extension announced in November 2025 has been executed and what it does for this lease. Remaining term drives both value and financing.
Model the PILOT on a market apartment. It phases in over ten years; if you buy mid-phase-in, you inherit the remaining steps. Run the True Monthly Carrying Cost Calculator with the actual maintenance and the scheduled increases, and the Co-op Board Qualification Calculator against the board's real requirements.
What to know if you’re selling
Lead with the documents. A buyer or lender who discovers the Affordability Plan, the sponsor position or the 2028 maturity late will stall the deal. Assemble the apartment's track confirmation, the current financial statements, the PILOT schedule and the RIOC transfer-fee calculation before the first showing.
If your apartment is restricted, price to the cap and qualify the buyer early. The buyer pool is limited by the income formula, and the flip tax on a first insider resale is large. Get the maximum price and the flip-tax computation in writing before you list.
If your apartment is a market apartment, you are competing with the sponsor. Renovated sponsor inventory sets the ceiling on comparable apartments. Know what the sponsor has available and at what terms.

How to read the facts on this page. Items attributed to an offering plan describe the building as it was offered at that filing — unit mix, square footage, the amenity program as planned. They are not a statement about how the building operates today. Tax and compliance figures are sourced separately to current City records and carry their own dates. House rules, staffing and fee policy can change by board resolution without any public filing: treat every policy line here as a starting point for diligence and confirm it with the managing agent. Where this page compares one building or neighborhood to another, that is our analysis of the recorded record — it names the measure, the period and the sample it rests on, and it is an observation about medians rather than a prediction about any particular apartment.
