BXP closed a $1.2 billion construction loan for its 46-story, 930,000-square-foot office tower at 343 Madison Avenue. The loan funds 60% of the $2 billion project and carries a four-year initial term with a one-year extension option. The interest rate starts at Term SOFR plus 2.50%, dropping 25 basis points upon meeting leasing and construction milestones.
The four-year term is standard for construction loans, but the pressure is real. BXP must achieve substantial pre-leasing before 2030 to refinance or sell. The building is 50% pre-leased, with anchor tenant Starr (275,000 square feet) and law firm McDermott Will & Schulte (150,000 square feet). BXP executives say negotiations with two more tenants could push pre-leasing to nearly 70%.
CEO Owen Thomas plans to lease the top floors closer to delivery to command market-leading rents, reportedly targeting $350 per square foot. That strategy depends on continued rent appreciation and tenant demand for premium space. If demand softens, the project could become over-levered, forcing BXP to accept lower rents or inject more equity.
The loan's competitive terms—led by Wells Fargo, Bank of America, Bank of New York Mellon, and JPMorgan Chase—reflect lender appetite for trophy assets with a top-tier sponsor. But one $1.2 billion loan does not signal a broad reopening of construction debt. It is an outlier for a prime Midtown location with direct Grand Central access.
BXP is also selling down its interest, targeting 30% to 50% equity partners. An $80 million letter of intent with one partner is expected to close this quarter. The equity sale reduces BXP's exposure but also means sharing future upside.
The clock is ticking. BXP must deliver on pre-leasing promises to avoid costly refinancing or equity dilution. Tenants like Starr and McDermott Will & Schulte are betting on future demand, committing to a building that won't deliver until 2029. The loan is a bet on tenant demand recovery in Midtown—and the next few years will show whether that bet pays off.
