Northwind Group just wrote a $219 million loan for the office-to-residential conversion at 100 Wall Street, and the number matters more than the address.
This is the fourth nine-figure conversion loan to hit Lower Manhattan and Midtown in the past two weeks alone — Rudin's $175 million at a Midtown tower, Commonwealth's $114 million on the Mag Mile equivalent uptown, and now Northwind's $219 million on Wall Street. Lenders that spent 2024 and 2025 treating office-to-resi as a niche bet are now writing checks the size of a small hospital job.
For a GC or a gut-renovation sub, that's the signal that matters more than any single building. A $219 million construction loan doesn't fund itself — it funds framing, MEP rough-in, elevator modernization, and facade work at a scale that keeps a full crew on-site for two to three years. Office towers built in the 1960s and '70s have deep floor plates that fight natural light, which means these conversions lean harder on core rebuilds — new risers, new shafts, sometimes light wells cut through the slab — than a typical gut renovation would.
Northwind has been the go-to lender for this exact play; the firm has now written conversion debt across multiple boroughs this cycle. The pattern worth tracking isn't the building, it's the lender showing up again and again on the same trade: whoever's doing Northwind's structural and MEP scopes on one job is a good bet to see the same call again on the next one.
The building's exact scope — unit count, floor count converted — wasn't stated in the loan announcement. What's confirmed is the number and the use: office-to-residential conversion financing, one more entry in a stack that's now well past $500 million in the last month alone.
If you're bidding core-and-shell or MEP work on conversions, this is the moment to have your qualifications packet ready — the lenders are moving faster than the buildings are getting announced.
