A Private Pricing Opinion — what your apartment at The offering plan is filed as "Mercantile Library Condominium" 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.
17 East 47th Street is an eight-story building dating to 1932, built for the Mercantile Library, on a 2,500-square-foot lot a short walk east of Fifth Avenue. It was classed as a library in the city's records. Its owner, 17 E47 Acquisition LLC, filed a condominium plan on October 31, 2025 to convert it to 18 residences and one commercial unit.
The plan is thin on public detail. The record shows the sponsor, its counsel and the price, and no amendments. No design team, floor plans, amenity list or marketing had been published as of October 2026. An earlier proposal, reported in 2014, would have extended the building into a hotel; published sources do not say whether that scheme was built or dropped, and the current plan supersedes it.
For buyers and brokers tracking Midtown East condominium supply, this is a pipeline item now and a pricing reference once the plan is accepted.
Architecture and residences
The city's lot record gives an eight-story building of about 17,100 square feet, built in 1932, zoned C5-3. A 2015 Department of Buildings alteration filing covered a new certificate of occupancy for commercial and community-facility use and interior work on all floors, so the interior has been reworked before. No filing for the residential conversion is cited here.
Unit mix, sizes, ceiling heights, finishes and outdoor space are not yet published; the plan's unit schedule will set them.
Offering and pricing
Per the offering plan submitted to the New York State Attorney General (CD250356), the plan was submitted October 31, 2025 and carries an initial and current total offering price of $38,543,217 for 19 units (18 residential and one commercial). No acceptance, effective date, units-sold figure or amendment appears on the record.
The total includes the commercial unit, and the record does not show how it is allocated, so it does not support a per-residence price. Asking prices had not been published as of October 2026. Earlier commercial marketing of the building as a vacant sale is not relevant to condominium pricing.

What to know if you’re buying
No contracts yet. Until the Attorney General accepts the plan, the sponsor cannot sign binding purchase contracts, and the plan can change materially in review. Treat every figure here as provisional.
Deposit and contract. Sponsor contracts typically require a deposit of about 10 percent of the price, often split between signing and a later date. The Attorney General's statistical record for this plan shows a $15,000 deposit entry; the plan sets the actual schedule.
Taxes at closing. In sponsor sales the buyer customarily pays the state and city transfer taxes plus the state's graduated mansion tax on residential purchases of $1 million and up, plus title and lender costs. Use the calculators below.
Closing on a temporary certificate of occupancy. Conversions commonly close on a temporary certificate of occupancy, the city's interim sign-off that the building is safe to occupy while final items remain open. The plan will describe how the sponsor completes open work.
Common charges and taxes. The plan's budget will project both. The plan's tax disclosure states whether one applies and when it phases out. The sponsor controls the board until owners elect one under the declaration.
Building-specific points. Check what the plan says about the commercial unit's use and its effect on common charges, and about construction status. The plan classifies the work as a rehab, so the scope of work should be spelled out.

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.
