What the record shows

Round trips Haas, Mark appears on both sides of three buildings — bought, then sold. The shortest hold was 5800 Arlington Avenue at 1.4 years. Where both prices were recorded, the resale came in lower by $31,000.

Bundled closings two buildings changed hands on a single day, 2025-04-30. Same-day multi-building transfers are portfolio deals rather than individual sales, and the buildings in them usually keep sharing an owner afterwards.

Repeat counterparty RIX, KRISTEN; RIX, NATHAN is on the other side of two of these transfers. A name that recurs across deeds is usually an affiliate, a lender, or the same principal filing under a second entity — it is not by itself evidence of either.

Activity window Recorded activity for Haas, Mark runs from 2002 to 2025. The most recent filing is recent enough that the holdings below are likely still current.

Spread across boroughs The buildings span two boroughs, led by Manhattan with six. Buying across boroughs points at an investor rather than a neighbourhood operator.
