Every loan the CMBS tape reports against this building, as each trust filed it. A
building is the grain here, not the loan: this one is collateral in
8 separate trusts,
and the slices below are the pieces of its debt, not four different buildings.

The asset-level exhibit names up to three tenants per
slice; where the trusts name different ones, all of them are listed.
- Built from SEC Regulation AB II asset-level filings (Form ABS-EE, Item 1(a) exhibits) as filed by each trust’s depositor. Latest filing on this building: 2026-10-02.
- Rebuilt nightly. A slice that left its pool is excluded by the tape’s own latest-filing cut, so this page shows live debt only.
- Figures are as each trust filed them and are not restated, reconciled or scored here.
See the whole picture, not just the tape.
These pages publish the CMBS tape in aggregate, and one page for every building on it. The platform goes loan‑by‑loan: stress scores, special‑servicing transfers and the servicer's own filed commentary, the originators and trusts behind each loan, and your own book against all of it.
