Back in 2018 they bought a portfolio of about 53 buildings from another landlord, so they've got a bunch. The article mentions 655 West 160th Street and I know they're also facing foreclosure on their buildings at 4300 Broadway and 121 West 116th Street.

Go to https://whoownswhat.justfix.org/en/ and plug one of the addresses mentioned in the article into the search (like, 655 West 160) and that'll pull up a profile for the building that includes map showing associated buildings. Not all the dots on the maps are owned by Sugar Hill Capital Partners, but it's mostly accurate.
