A Private Pricing Opinion — what your apartment at 330 East 70th 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 a low, wide postwar co-op. It has six stories on a 139-foot frontage, where most Lenox Hill postwar buildings are towers. The building covers five former tax lots (31 to 35) near First Avenue. It has 74 apartments, a doorman and a garage under the building. It is a manageable size and has a working balance sheet.
The same owner held the building for 25 years. Three Thirty Company bought it the year it was finished and sold it to the tenants' corporation at the start of 1983. The offering plan sold shares to tenants at $800 a share and to outside buyers at $1,500. Rent-stabilized tenants kept the protections the law gave them in a conversion.
The garage matters. It is leased to an operator for a fixed rent that rises 1 percent a year, about $130,000 in 2026. The lease runs to September 2032. That income was about 6 percent of the co-op's 2025 revenue and keeps maintenance lower than it would otherwise be.
The next decision is the mortgage. The co-op's loan matures on August 1, 2028, with about $2.8 million due at maturity. The board will have to refinance or restructure it within the next two years. A buyer should ask where that stands.
Architecture and unit composition
The engineer's report in the offering plan describes a six-story elevator apartment building. It is 139 feet across the front, 117 feet across the rear, 80 feet deep and 62 feet high. It has about 54,600 square feet of floor area, zoned R8 when the plan was filed. Cars enter the garage at the east end of the building, per the house rules. The report counted a 25-car garage and four professional offices. The house rules still refer to doctors' offices in the building.
The documents we hold do not include room counts or layouts for each apartment. Ask the managing agent for the floor plan of any apartment you are considering.
Building operations
Underlying mortgage. In July 2018 the co-op refinanced with a $3.5 million loan at 3.75 percent, on a 30-year schedule. About $2.97 million was outstanding at the end of 2025, or $633 a share, and the loan matures August 1, 2028, per the audited statements. At a 2028 refinancing, the rate will probably reset from 3.75 percent to current market rates.
Capital work. In 2024 the boiler was replaced and the building converted to gas heat. A roughly $250,000 capital assessment helped pay for it, and the project came in under budget. A façade repair contract of about $248,000 was signed in February 2025. A second capital assessment of about $350,000 began in December 2025, payable over nine months, to fund it. The façade was rated safe with a repair and maintenance program in its most recent DOB façade inspection (Cycle 9, 2022).
Reserves and maintenance. The co-op held about $259,000 in its reserve fund and $266,000 in operating cash at the end of 2025. Maintenance rose 1.5 percent in January 2026. There is no reserve study, which is normal for New York co-ops.
Garage lease. The current operator took possession in October 2022 on a ten-year lease that expires September 30, 2032.
Policy framework
Flip tax. 3 percent of the gross sale price, per the 2025 audited statements. Who pays is not stated. Confirm at offer stage.
Subletting. Owners may sublet after two years, for up to three years in any five-year period. Leases run one year or less, need board approval to renew, and carry a sublet fee, per the 2002 house rules.
Pets. No dogs, per the 2002 house rules, with an exception for dogs already living in the building. The rules may have changed since 2002. Confirm the current policy.
Guests. Houseguests may stay only while the shareholder is in residence, per the house rules.
Renovations. Work is allowed 9 a.m. to 5 p.m. on weekdays. Structural work needs an alteration agreement, and cosmetic work needs a decoration agreement. At least 80 percent of each room's floor must be carpeted, except kitchens, baths and closets.
Not documented. The financing ceiling, post-closing liquidity rule (cash left after closing), pied-à-terre policy and trust or LLC ownership rules. These must come from the managing agent.

Sublet and pied-à-terre policy

The latest available filing classified the facade as SWARMP — Safe With A Repair and Maintenance Program: the inspector (QEWI) identified conditions requiring monitoring or repair, with repairs due by the deadline stated in the filing. The scope, timeline, and how the building funds the work are building-specific — we review the filings and board materials for you.
How to read this, and where it comes from
QEWI = Qualified Exterior Wall Inspector — a licensed professional engineer or registered architect who meets DOB’s FISP qualifications and signs the report (the independent expert, not the managing agent).
Penalties shown are amounts DOB assessed against filings on record across 2005–10 to 2020–25. The FISP dataset does not record whether they were paid, contested or remain open, so treat the figure as history rather than a current balance and confirm the building’s standing with the managing agent.

Recent sales
Buyers compare this building with other postwar doorman co-ops in the East 60s and 70s. Prices are quoted per room. The co-op reported transfer-fee income of $8,250 in 2024 and $36,000 in 2025. Revenue depends on sale prices, fee rules, exemptions and timing, so it does not by itself establish the number or pace of trades across 74 apartments. The reviewed statements report garage income and mortgage debt of about $630 per share. Assess those figures alongside current expenses, reserves and capital obligations; the 2028 loan maturity is one cost consideration, not the only source of change. Unit-level transaction history is maintained in The Roebling Research Library and shared with clients during diligence.

What to know if you’re buying
Ask about the 2028 refinancing. Ask whether the board has started talking with lenders and what it expects the new rate to do to maintenance.
Check the façade assessment. The $350,000 assessment began in December 2025 and was payable over nine months. Confirm it is fully paid and that the façade work has been signed off.
Get current house rules. The rules we hold date from 2002. Pet and sublet terms in particular should be confirmed.
What to know if you’re selling
Lead with the completed work. A new gas boiler and a funded façade repair are the questions buyers ask first. Have the managing agent's letter ready.
Frame the mortgage. Give buyers the maturity date and the board's plan before their attorney asks.

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.
