Sale history
| Recorded | Price | Qualification | Source | Instrument |
|---|---|---|---|---|
| Jun 2015 | $40,500,000 | not rated | County roll | — |
Prices are the consideration recorded in Washington, DC's public property records. Where a qualification code exists it is the assessor's judgement of whether a transfer was arm's length; transfers without one appear unrated rather than assumed clean. Whether a building is on the market today, and at what price, is not a public record and is not shown here — asking prices, listings and lease terms live in private commercial databases.
