Who was on the other side
Three of these deeds move a building from one MBSD company to another rather than to an outside buyer. Those are restructurings, not sales, and most of them state no price. On the rest, the record names Calderon Grace A, Phantom Capital 161 LLC.

How the record links these companies
Two independent things in the public record have to agree before MBSD is treated as one group: a shared naming pattern across numbered siblings, and a shared mailing address on the deed filings. One signal alone is not enough, and roughly seven in ten shared-address groups fail the test and appear nowhere on this site. This is a documented link, not a finding about ownership. The deeds say these companies share a name and a mailing address. They do not say who controls them. The full method, and the other networks.
Common questions
Who is MBSD?
MBSD is the name shared by 5 limited liability companies that appear as parties in the NYC deed record, holding 5 buildings between them. The deed record shows the shared name and the shared filing address; it does not name the people behind the companies.
How many NYC buildings does MBSD own?
5 buildings across 5 companies, counted from deeds filed with the city. Condominium unit deeds are collapsed to the building they sit in, so a whole-condo purchase does not read as a portfolio.
Why is MBSD split across so many companies?
Holding each building in its own limited liability company is standard practice in New York: it separates liability between buildings, simplifies financing and makes a later sale cleaner. The side effect is that one owner appears in the public record as many unrelated names, which is what this page undoes.
Have there been evictions in MBSD buildings?
2 executed marshal evictions appear across 1 of its buildings. PulseCities reports what the public record contains and makes no claim about why any eviction happened.
