Who is the tenant, and what's the lease?
There is no single corporate tenant: these are apartments rented by residents. Groma NAV REIT's financial statement notes state that the Trust leases its properties to a master-tenant entity, accounted for as an operating lease; the available excerpt does not name that master tenant or give lease dates or rent.2
How did it end?
Still operating
No evidence of sale or full cycle; the Charlestown Boston multifamily portfolio (e.g., 25 Caldwell Street) remains listed on Groma's holdings website and the Groma NAV REIT Q1 2026 PPM reflects a continuing operating multifamily portfolio with no disposition reported for the Groma III DST (Groma Holdings / Groma NAV REIT PPM Q1 2026).

How is it financed, and what does it pay?
The Trust's buildings carry mortgage debt rather than being owned free and clear, so investor equity sits behind a lender's claim. Needham Bank provided $3.55 million of financing when Groma acquired the buildings in February 2024. The public record reviewed does not show the loan's current balance or terms.

Who occupies the buildings?
They are residential apartments leased to individual residents rather than a single corporate tenant. Groma NAV REIT's financial statement notes describe the Trust leasing the properties to a master-tenant entity under an operating lease; that entity is not named in the excerpt reviewed, and no current occupancy figure is established. Groma reported the portfolio as 100% occupied at the March 14, 2024 launch.

Can this Trust convert into REIT shares through a 721 exchange?
The record does not show a 721/UPREIT exit — that is, an option to contribute the property into a REIT's operating partnership in exchange for REIT units at the end of the hold. Investors relying on any exit mechanic should confirm it in the Private Placement Memorandum (PPM), the offering's governing disclosure document.
What is not known about this offering?
No amendment, new Form D, or disposition filing for the Trust was located after the October 1, 2024 filing, so current status, occupancy, master lease terms, and current debt balance are not established. The offering's own PPM and the sponsor are the sources for those items.
