434 East 52nd Street, Manhattan

A pre-war co-op where the building's quiet city record is undercut by a rare foreclosure.

This is a 71-unit co-op from 1930. The city's operational records are exceptionally clean, which in a private building like this points to effective internal management. A look at recent sales, however, suggests a more complex picture. Three things to know:

A bank recently sold a unit after a foreclosure. A March 2025 sale was from Fannie Mae. Foreclosures in co-ops are rare and messy — it means a shareholder defaulted, the bank took their shares, and the board had to negotiate the sale. While it's a single unit, it's a material event.

The building's day-to-day operations are quiet. The city has almost no record of internal problems. A single heat complaint affecting the entire building in November 2025 was resolved quickly. For a co-op, this near-silence means issues are being handled through the managing agent, not through city agencies.

There's no public record of recent capital work. No permits for major work have been filed with the city recently. For a building of this age, that can be a flag for deferred maintenance on big-ticket items like the elevators, facade, or boiler.

Quieter signals on this building and the blocks around it:

• An estate sale in late 2024 and another sale from an LLC in 2023 add to the varied ownership texture.
• Neighbors are attentive to the street, with a handful of 311 complaints about illegal parking and street lights.
• The head officer of the co-op board is listed as Daniel Neuman.
