Which statement correctly describes the difference between fixed-rate and adjustable-rate mortgages?

• A. Fixed-rate payments change with market conditions, while ARMs lock in a rate.
• B. ARMs always have fixed rate for life.
• C. The only difference is the lender; otherwise both are identical.
• D. ARMs have higher initial payments and never adjust.

Answer: (C)

Rate structure drives how predictable your housing costs will be. A fixed-rate mortgage locks the interest rate for the entire loan term, so the monthly payment of principal and interest stays essentially the same over time (ignoring changes in taxes or insurance you may escrow). In contrast, an adjustable-rate mortgage sets an initial rate, but after an initial period that rate can change based on a benchmark plus a margin, which means the monthly payment can go up or down over time. ARMs often start with a lower rate than fixed-rate loans, but they carry the risk of higher payments later as rates rise. The difference isn’t just who lends you the money. It’s about how the rate behaves over the life of the loan. The idea that fixed-rate payments change with market conditions isn’t correct, because the rate is fixed. The idea that ARMs fix the rate for life isn’t correct, because the rate adjusts. ARMs also aren’t guaranteed to have higher initial payments or to never adjust; they typically begin with lower payments and then adjust according to the terms and caps of the loan.
