Amortization describes the process of paying down a loan's principal balance over a set schedule, typically through equal periodic payments that combine principal and interest. Early in an amortization schedule, a larger share of each payment covers interest; as the balance shrinks, more of each payment applies to principal. Commercial mortgages often use amortization periods longer than the loan term itself, meaning the loan comes due before it is fully paid off, requiring refinancing or a balloon payment at maturity.
For investors evaluating a sponsor's debt structure, amortization matters because it directly affects cash flow available for distributions. A longer amortization period lowers monthly debt service and frees up cash in the near term, while a shorter period builds equity faster but reduces distributable income. Understanding how a deal's amortization schedule interacts with its projected hold period helps investors gauge both current yield and eventual refinancing risk.
