A real estate loan payable in periodic installments that are sufficient to pay the principal in full during the term of the loan is called a(n)...

An amortized loan is defined by its structure of periodic payments that include both principal and interest, allowing the borrower to pay off the loan in full by the end of its term. This means that each payment reduces the principal balance along with covering the interest accrued, ensuring that by the completion of the loan period, the entire amount borrowed has been repaid.

The principal characteristic of an amortized loan is that the scheduled payments are set so that the loan will be completely paid off once the last installment is made. This is in contrast to other loan types, such as interest-only loans, where the borrower only pays the interest during the term and the full principal is due at the end. Balloon loans also do not fully amortize over the loan term, resulting in a large final payment due after a period of smaller payments. A fixed-rate mortgage refers to the interest rate stability over the life of the loan, but it doesn't specifically address the repayment structure that includes full principal repayment through periodic installments. Thus, the amortized loan is the correct term that describes a loan repaid in this manner.
