Fixed vs Adjustable-Rate Mortgages
Should your rate stay the same for decades or start lower and adjust later? Understanding the trade-off helps you choose with confidence.
Fixed-rate: stability
A fixed-rate mortgage keeps the same interest rate and principal-and-interest payment for the entire term. It's predictable and simple, which many buyers value highly.
Adjustable-rate: lower start, later change
An adjustable-rate mortgage (ARM) typically starts with a lower fixed rate for a set period, then adjusts periodically based on market conditions. It can fit buyers who expect to move or refinance before the adjustment period begins.
Key takeaways
- Fixed rates offer predictability for the full term.
- ARMs start lower but can rise after the intro period.
- Your expected time in the home guides the choice.
