Big money investors pumped billions into buying up apartment buildings in the pandemic era. But fault lines have emerged for investors who paid top dollar for assets that depended on substantial rent increases and persistent low interest rates to achieve profitability. In those years, investors purchased $355.5 billion and $299.2 billion worth of apartment buildings, according to MSCI — unprecedented sums that far surpassed the previous $194 billion record of multifamily sales in 2019. "It's early, but it's going to become a bigger story, especially if interest rates stay high and lending standards are tight," said Alan Todd, the head of commercial-mortgage-backed-securities strategy at BofA Global Research. As these short-term debts come due, they will be difficult to swap with commensurately sized loans today, because of the falling values, higher interest rates, and lender caution.
