A Private Pricing Opinion — what your apartment at 52 East 78th Street & 61 East 77th Street 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.
This is one cooperative in two buildings, and both were built as a school. In 1916 the architects Harde & Hasselman designed a pair of tall school buildings back to back on the block between East 77th and East 78th Streets for the Finch School — a neo-Gothic tower on 78th Street and a neo-Federal building on 77th Street, filed under a single permit, per LPC. The client of record was Mrs. John O'Hara Cosgrave; Jessica Garretson Finch, the school's founder, had married Cosgrave in 1913. The school became Finch College, a women's college, and held both buildings for six decades.
After the college closed in the 1970s, ACRIS shows the property passing from Finch College, through the Dormitory Authority of the State of New York, to a private owner in 1977–78. The new owner converted both buildings to apartments with a J-51 benefit begun in 1979, and in 1984 the sponsor deeded both lots to Finch Apartment Corp. The corporation has owned the two buildings as a single cooperative since.
The practical point for a buyer is that the address on the listing is only half the co-op. A shareholder at 52 East 78th owns shares in a corporation that also owns 61 East 77th Street, shares its mortgage, and shares the income and obligations of roughly 14,700 square feet of commercial space across the two ground floors. The public record lists 47 apartments at 78th Street; the corporation has 98.
Architecture and unit composition
52 East 78th Street. LPC describes a twelve-story neo-Gothic school building of brick and stone on a lot about 40 feet wide. The two-story entrance is flanked by stone pinnacles with crockets and by two-story window bays framed in stone, a stone balcony railing runs across the front, and the top three floors are stone treated to resemble tracery windows. It replaced two rowhouses. A 1930 interior alteration by George F. Mitchell is the only one LPC records before the residential conversion.
61 East 77th Street. LPC describes a ten-story brick and limestone school building in a neo-Federal style with Beaux-Arts features: a limestone ground floor and garlands, oversize second-floor window enframements with triangular pediments, arched seventh-floor windows, dormers above the cornice and copper wreaths at the tenth floor. It replaced three 1877 rowhouses. A ten-story addition at No. 65, faced in limestone at the base, was built in 1965.
The apartments. The conversion put apartments into floor plates designed for classrooms, so layouts vary more than in a purpose-built prewar co-op. DOB filings since 2000 show that variety: an apartment split from 3ABC into 3AB and 3C in 2011, the combination of 4C and 4D in 2013, and duplexes at 8A/9A and on the tenth and eleventh floors at 52 East 78th. The original offering plan's unit schedule was not reviewed. Price each apartment on its own plan.
Building operations
One corporation, two buildings, one mortgage. The underlying mortgage is recorded against both lots. ACRIS shows a refinancing in August 2010 and a consolidated refinancing in October 2018. The maturity and rate are not in the public record; get them from the audited financial statements. Ask too how common charges, reserves and capital work are allocated between the two buildings.
Commercial income. Both ground floors carry non-residential space, and ACRIS records long-term leases on it from 1986 onward, including leasehold mortgages by commercial tenants. For a co-op this size, rent from that space can be a meaningful part of the operating budget, and a lease expiry can move maintenance. Ask for the lease terms and expiry dates.
Façade and landmarks. DOB filings show façade restoration at 52 East 78th in 2008, with scaffolding the height of the building, and further façade repairs filed in 2019. The ornamented stone at the top of the 78th Street façade and the limestone of the 77th Street building are the kind of work that recurs under Local Law 11 inspection cycles, and in the historic district it goes through LPC as well. Ask for the current façade report and any open work.
Taxes. The J-51 benefits from the conversion ended decades ago. Real estate taxes are carried in maintenance, and eligible primary-residence shareholders receive the cooperative abatement.
Recent sales
Finch Apartment Corp. trades as a prewar-era Upper East Side co-op between Madison and Park, priced per room, with a conversion's variety of layouts. With 98 apartments across the two buildings, ACRIS records a steady flow of share transfers — several a year at 61 East 77th and a smaller number at 52 East 78th. Floor, light, ceiling height and how well the conversion layout works decide value inside the co-op; the upper-floor duplexes at 52 East 78th are the outliers. Comparisons belong with the side-street prewar co-ops of the Upper East Side Historic District, adjusted for the conversion floor plans. Unit-level transaction history is maintained in The Roebling Research Library and shared with clients during diligence.

What to know if you’re buying
You are buying into both buildings. Review the financials for the whole corporation. Ask how costs are split between 52 East 78th and 61 East 77th and whether either building has capital work pending.
The board package is the gate. Expect a full financial package and an interview. The board's financing ceiling, minimum down payment and post-closing liquidity requirement are not documented publicly; ask for them before you make an offer.
Get the policy stack in writing. Subletting, pied-à-terre use, purchases through trusts or LLCs, pets and any flip tax must come from the managing agent.
Read the commercial leases. The ground-floor tenants' rent supports the budget. Find out when the leases expire.
Plan renovations around LPC. Interior work goes through DOB; anything visible on the façade or roof also needs LPC approval.
What to know if you’re selling
Lead with the history. The Finch School origin, the neo-Gothic façade and the historic-district setting between Madison and Park set this co-op apart from the post-war stock on the same blocks.
Explain the structure up front. Buyers and their attorneys will find the second building in the records. Explaining the two-building co-op in the listing avoids a surprise in diligence.
Show the plan. Converted classroom floors produce unusual layouts. A measured floor plan does more for the sale than a room count.

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.
