Initial Interest Rate
The starting interest rate on an adjustable-rate mortgage (ARM) during the initial fixed-rate period before any adjustments occur. This introductory rate is often lower than current market rates for fixed mortgages and remains constant for a predetermined period, such as 1, 3, 5, 7, or 10 years.
Example
“The ARM offered an attractive initial interest rate of 3.5% for the first two years before adjusting to market rates based on the index.”
Memory Tip
Initial interest rate = 'Initially interesting rate' - it's interesting (attractive) at first, but it's just the beginning rate.
Why It Matters
The initial rate determines your starting monthly payments and can provide significant savings compared to fixed-rate mortgages during the introductory period. However, borrowers must prepare for potential rate increases when the adjustment period begins.
Common Misconception
Borrowers often mistakenly believe the initial interest rate will remain the same throughout the loan term, not realizing it's only temporary before adjustments begin.
In Practice
A 5/1 ARM might offer an initial interest rate of 3.5% for the first five years when fixed-rate mortgages are at 4.5%, saving the borrower approximately $150 monthly on a $400,000 loan before the rate becomes adjustable.
Etymology
Combines 'initial' from Latin 'initialis' (beginning) with 'interest' from Latin 'interesse' (to be between/among) and 'rate' from Latin 'rata' (calculated portion), referring to the starting calculated portion of borrowing cost.
