Prospectus ID: 2
Park Square, a 503,312 SF office building located in the Back Bay neighborhood of Boston, MA, originally constructed in 1923 and subsequently renovated between 2014-2016. WeWork, which represented 27% of the GLA (137K SF), terminated its lease. Lender was also notified that Borrower will cease to fund any shortfalls out of additional capital contributions by its equity owners. Lender is currently trapping all cash flow from the Property. A Notice of Default and Reservation of Rights has been sent. As of the 12/31/2024 YE financials, the NOI/DSCR/Occ. at the property is $491K/ 0.07x/ 42.8%. The Borrower has engaged Iron Hound as a third-party advisor to support ongoing modification discussions. No modification or workout agreement has been reached to date. The Special Servicer will gather additional information and simultaneously discuss workout strategies deemed appropriate to achieve the highest net present value recovery.
