A Private Pricing Opinion — what your apartment at 21 Astor Place 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.
21 Astor Place is the converted 1890 New York Mercantile Library / Clinton Hall — successor to the Astor Place Opera House.
That Mercantile Library / Clinton Hall provenance, carrying the cultural lineage of the Astor Place Opera House, is the building's defining inheritance. It survives in the Romanesque Revival composition of George E. Harney, whose arched brickwork still reads as a nineteenth-century institution rather than an apartment house. The residences themselves are the product of the 2003 Elad Group conversion, which carved roughly 50 condominium units out of the old library, many retaining exposed brick and fireplaces.
Architecture and building operations
Originally housed the New York Mercantile Library / Clinton Hall — successor to the Astor Place Opera House. 11-story brick with arched windows, exposed brick interiors, fireplaces in many units. Among the earlier Astor Place adaptive reuse projects.
Operations: concierge; full-time doorman; health club; fireplaces. Retail at base.

Sublet and pied-à-terre policy
A condominium owner leasing a unit and a co-op shareholder subletting are different rules, and a building-wide rule is different from a restriction on one apartment. This is the building's rule; confirm it for the specific apartment.

Common charges plus real estate taxes, combined into one monthly figure the way New York condominium listings show them. Add a mortgage payment for the monthly outlay. The split into common charges and taxes comes from the listings that also give the annual tax, a different sample, so the two lines need not add up exactly to the combined median; a tax abatement can hold taxes below the full amount until it expires. A summary of recorded sales and listings, not a current bill; charges change.

The latest available FISP filing classified the facade as Safe — no repairs were required at that inspection. Facade inspections run on a fixed five-year cycle; future inspection, repair, and any assessment decisions remain building-specific.
How to read this, and where it comes from
QEWI = Qualified Exterior Wall Inspector — the licensed engineer the city requires to sign 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.

Market read. Most recent trades (2025) cleared a median $1,759/sf (floor-adjusted) across 3 sales. Floor-adjusted means each sale is restated to a constant mix of floors, so the figure can differ from the plain median of the sales listed above. Median listing discount 4.5% from the last ask — a recurring negotiation gap worth pricing into any offer or listing strategy.

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.
