Final answer:
a) Adjustable-rate mortgage
If inflation falls unexpectedly by 3%, a homeowner with an adjustable-rate mortgage would likely benefit from a reduced interest rate, leading to lower monthly payments, but they face the risk of rising payments if inflation increases.
Step-by-step explanation:
The question deals with an adjustable-rate mortgage (ARM), which is a loan for purchasing a home with an interest rate that varies alongside market interest rates, often influenced by inflation. If inflation falls unexpectedly by 3%, a homeowner with an ARM would likely experience a decrease in their interest rate. This is due to ARMs typically having built-in inflation adjustments, meaning that when inflation rates decrease, the interest rates on the loan adjust accordingly. Conversely, if inflation increases, the interest rates on ARMs would rise.
Therefore, in a scenario where inflation falls by 3%, the homeowner with an ARM could benefit from lower monthly payments. However, it's important to remember that this benefit comes with the risk that if inflation rises, the homeowner's payments could increase significantly.
