When you take out a mortgage, one of the big decisions is choosing a fixed-rate or an adjustable-rate mortgage (ARM). This choice affects your monthly payment for years, so understanding both types will help you avoid surprises down the road.
What is a fixed-rate mortgage?
With a fixed-rate loan, the interest rate stays the same for the entire term, usually 15 or 30 years. Your monthly principal and interest do not change. Your total payment can still rise if property taxes or insurance go up, but the loan's interest portion is locked.
- Pros: stable, easy to plan around, no worry about market rates rising.
- Cons: the starting rate is usually a bit higher than an ARM; if market rates fall, you must refinance to benefit.
What is an adjustable-rate mortgage (ARM)?
An ARM has an initial fixed period, after which the rate changes periodically with the market. You will see names like 5/6 ARM or 7/6 ARM: the first number is the fixed years, the second is the adjustment cycle (every six months). For example, a 7/6 ARM is fixed for seven years, then adjusts every six months.
- Pros: the starting rate is usually lower than fixed, so early monthly payments are lighter.
- Cons: after the fixed period, the rate can rise and your payment rises with it.
The protective caps in an ARM
ARMs have caps that limit how much the rate can climb: a cap on the first adjustment, a cap on each later adjustment, and a lifetime cap for the whole loan. Ask about these numbers carefully, because they tell you the worst-case payment you could face.
When is fixed the better choice?
- You plan to stay in this home for many years.
- You want peace of mind and a steady budget.
- Market rates are currently low and you want to lock them in.
When can an ARM make sense?
- You expect to sell or refinance within a few years, before the fixed period ends.
- Your job might require you to relocate.
- You want lower early payments and fully understand the risk of later increases.
One important caution
Do not choose an ARM just because the lower payment lets you buy a more expensive home. If you can only afford it during the low-rate period, you may struggle when the rate adjusts upward. Choose based on your life plan, not only the starting number.
