David Bistricer’s Clipper Equity just got a debt injection from Freddie Mac for an apartment complex that straddles the interstate leading to the George Washington Bridge. The owner entity secured a $136 million refinancing of the 480-unit Bridge Apartments. There are four, 32-story buildings in the complex. The main lender behind the debt is Walker & Dunlop, a Bethesda, Maryland-based commercial real estate finance firm.
