For all the predictions of office pain if not outright oncoming disaster, some areas were supposed to be in better shape — primary metro markets with high concentrations of business and a lot of Class-A office space that would stay sturdy because of flights to quality.

But according to Yardi's CommercialEdge, "office mortgage maturities signal coming distress," with those loans "concentrated in primary markets, Class A properties and urban areas."

The total amount of mortgages maturing by the end of 2024 are close to $150 billon, and nine metro areas will experience 20% of all office mortgages that come to maturity by then. This is out of 80,000 office properties with $920 in total mortgages. "Ten metros have more than $5 billion of office loans maturing through the end of 2024, and 10 have at least $10 billion of loans maturing by the end of 2026," they wrote.
