From a plugged-in tipster today:
351 California is one of the Dollar buildings (forgot which one), later the Pacific Bank Building, and currently the HQ [of] Brugnara Properties. Luke Brugnara is one of the most storied characters in the commercial real estate scene. The building is scheduled for the courthouse steps 14 November with an outstanding loan balance of $33,377,682 per PropertyShark.
From Brugnara seven months ago: “I own 351 California and am not in default.”
