CNBC reports that U.S. commercial real estate faces a "massive" wave of debt maturities over the next two years, with an estimated $733.2 billion in loans due in 2027. High interest rates have significantly increased refinancing costs, causing concern among some market participants, while other investors see this as an opportunity to acquire assets at attractive valuations. According to Trepp data, $800 billion in commercial real estate debt is expected to mature this year, and the delinquency rate for office commercial mortgage-backed securities (CMBS) rose to 12.16% in September.
