The $546 Million Office Building Discount

Boston, Oct. 28 — Rockpoint Group kept its 100 Summer St. tower — by buying it back at a foreclosure auction for $260 million, roughly $236 per square foot, on October 27. Bisnow reported that auctioneer Marianne Sullivan of Sullivan & Sullivan opened bidding at $260 million on the steps of the 1.1 million-square-foot building; Rockpoint was the sole bidder in a proceeding that lasted about 40 seconds, according to Banker & Tradesman.

The price is a 68% discount to Rockpoint’s $806 million acquisition from Blackstone in late 2019, months before the pandemic emptied cubicles. The arithmetic headline — $546 million of value gone — is the gap between those two trades, not a third-party’s opening ask.

How the Loss Routes

Wells Fargo held a $470 million mortgage on the 2019 purchase and moved to foreclose in September 2026, after Rockpoint defaulted. At $260 million, the auction clears the asset back to the sponsor while crystallizing a loss stack:

• Senior lender: Wells Fargo absorbs the difference between outstanding debt and sale proceeds — either through a credit mark, workout with insurers, or sale of the defaulted loan into distressed-debt markets.
• Equity: Rockpoint’s limited partners already suffered dilution of net asset value; buying back at $260 million resets the basis for any future recap but does not restore 2019 equity.
• Tenants and leasing: The tower was about 72% leased at auction, with 330,000+ square feet available, per auction materials. Tenants include SimpliSafe, which took 150,000 square feet in 2021 — leases that now anchor cash flow at a far lower building valuation.

The Boston Globe previewed the auction in September, framing 100 Summer as another downtown trophy forced into a public sale after remote-work drift and rising capital costs.

Exceptional Dollars, Familiar Pattern

100 Summer is not the only U.S. office asset repricing through foreclosure or deed-in-lieu, but the scale — nearly $806 million to $260 million on a fully leased-not-full tower — makes it a reference point. Distressed sales in San Francisco, Chicago and Washington have shown similar 50–70% haircuts on 1980s-vintage stacks that lack the amenity arms race of new Class A product.

Capital markets feel the lag. CMBS trusts mark loans on delinquency schedules; insurance companies that underwrote 2019 vintages face regulatory capital hits when appraisals catch up. Refinancing windows that assumed 4% cap rates on Boston Financial District rent rolls no longer close without equity checks that sponsors like Rockpoint struggled to write.

Buying back at auction is a workout tactic: shed the lender, reset basis, and attempt a long hold with lower debt — not a vote that downtown Boston office is healed.

What Would Change the Verdict

Comparable Boston foreclosure outcomes in the next two quarters would show whether $236/SF is the new clearing level for 1980s towers or a fire-sale floor. Lease-up above 80% with credit tenants would improve debt capacity even at lower absolute values. Falling policy rates would help refi math but cannot fix utilization if employers keep shrinking footprints. A surprise bid from a third-party buyer would have signaled market clearing without sponsor rescue — the absence of that bid matters.

For investors watching the commercial reset, 100 Summer is a labeled loss: $546 million of nominal value removed in one afternoon on Summer Street, with lenders and LPs still distributing the bill across portfolios that pretended office was a slow glide, not a cliff.
