A Private Pricing Opinion — what your apartment at The Diplomat 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.
204 East 47th Street — The Diplomat — is a postwar tan-brick condominium in Turtle Bay, converted from a rental to condominium ownership in 1985. The building spans 204–210 East 47th Street and is generally marketed under the 210 address, which is why the 204 number shows little independent sales presence.
Its architecture is distinctly of its era: an angled east wall, a driveway plaza set-back, corner windows, and terraces on some lines, wrapped in a marble lobby. The location places residents near Grand Central, the United Nations, and the Midtown business core.
Architecture and building operations
The thirteen-story building carries a 24-hour doorman, a concierge, a live-in superintendent, central air conditioning, central laundry, and an on-site garage. Some units include private terraces.
Inventory runs from studios through one-bedroom-plus layouts.

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 (2026) cleared a median $1,026/sf (floor-adjusted) across 1 sale. 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 2.8% 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.
