What type of loan typically has no set payment schedule?

An interest-only loan is characterized by the borrower making payments only on the interest accrued during a set period, typically the initial years of the loan, rather than paying down the principal balance. This means that for a certain timeframe, there is technically no fixed payment schedule for the principal portion of the loan, as those payments are deferred until the interest-only period ends. After this period, the loan may convert to a standard amortization schedule, or the entire principal may come due, depending on the specific terms of the loan agreement.

In contrast, a wraparound loan, open-end loan, and blanket loan each involve different structures and arrangements that include ongoing payment requirements. A wraparound loan wraps the existing mortgage into a new mortgage, requiring regular payments. An open-end loan allows for borrowing up to a certain limit and typically has a more flexible payment schedule, but still requires regular payments. A blanket loan usually finances multiple properties and, again, requires consistent payment on the outstanding principal and interest. Therefore, the nature of an interest-only loan makes it unique as it lacks a defined regular payment schedule for the principal during the initial phase.
