Michael Shah’s DelShah Capital is back at it again with another multi-address, multifamily acquisition. The real estate private equity and asset management firm paid Quality Capital USA $36.9 million for five residential buildings just west of Central Park on Manhattan’s Upper West Side, according to property records filed Thursday. The first batch of six-story apartment buildings are at 3-5 West 108th Street and 7-9 West 108th Street. Delshah’s purchase is a more than $20 million discount on the portfolio’s last sale in 2018, when Quality Capital USA paid Orbach Group $57 million across five transactions. Spokespeople for Delshah and Quality Capital did not immediately respond to requests for comment.
