Recent recorded apartment sales

The latest 12 qualifying records in our extract, including prices below $1 million. These are recorded sale amounts, not asking prices. Sponsor status and arm's-length resale status have not been individually verified. Matching same-date/same-price groups are excluded as possible bundles; this can also exclude genuine separate sales.

Use this table to select comparable apartments for further review. Floor, size, exposure, renovation and included rights may differ. No price-per-square-foot figure is calculated without verified apartment area. Annual sales records · Rolling sales records

Apartment layouts and floorplans

A verified floor-by-floor apartment map and reusable floorplan library are not yet available for this guide. Apartment labels in the sales table are record identifiers; they do not establish floor, bedroom count or a consistent layout across a line. We have not divided the unit total by the number of floors or guessed apartment sizes.

No matching entry was returned from the DOB NOW occupancy dataset. This is not evidence that the building lacks a certificate; older documents may be in BIS.

Façade filings to review

Latest dated filing per matched BIN in this extract. A filing classification is not a fresh inspection or a guarantee about present conditions. SWARMP means Safe With a Repair and Maintenance Program. Ask management for the latest accepted report, required work, contracts, budget and funding; a filing alone does not establish an assessment.
