Fixed vs. adjustable mortgage: which one suits you best?

Choosing the right mortgage rate is a critical decision for home buyers. It determines not only the monthly payments but also the total cost of the loan over time. While some borrowers prefer the predictability of a fixed-rate mortgage, others may benefit from the initially lower rates of an adjustable-rate mortgage (ARM).

Understanding the differences between these two options is essential to making an informed financial decision. This article explores how fixed and adjustable mortgage rates work, their advantages and disadvantages, and how to determine which one is best suited for your financial situation.

What is a mortgage rate and why does it matter?

A mortgage rate is the interest charged by a lender on a home loan. It affects the total cost of borrowing and influences how much a homeowner will pay each month. Mortgage rates fluctuate based on economic conditions, Federal Reserve policies, and an individual’s financial profile.

Lenders determine mortgage rates based on several factors:

• Credit score: Higher scores usually qualify for lower interest rates.
• Loan-to-value ratio (LTV): A larger down payment often results in better rates.
• Loan term: Shorter-term loans typically have lower interest rates than longer-term loans.
• Debt-to-income ratio (DTI): Lenders assess financial stability before offering a rate.

Borrowers should also consider the APR (annual percentage rate), which includes the interest rate along with any fees and costs associated with the loan.

What is a fixed-rate mortgage?

A fixed-rate mortgage maintains the same interest rate throughout the life of the loan, meaning that monthly payments remain constant. These loans are typically available in terms of 15, 20, or 30 years, with 30-year fixed mortgages being the most common choice among homebuyers.

Pros and cons of a fixed-rate mortgage

Pros:

• Predictable monthly payments, making budgeting easier
• Protection against rising interest rates in the future
• Ideal for long-term homeowners who plan to stay in their homes for many years

Cons:

• Higher initial interest rates compared to adjustable-rate mortgages
• Borrowers may miss out on lower rates if market conditions change
• Less flexibility in adapting to economic shifts

What is an adjustable-rate mortgage (ARM)?

An adjustable-rate mortgage (ARM) starts with a lower fixed interest rate for an initial period, usually 5, 7, or 10 years, before adjusting periodically based on a benchmark index. These adjustments can increase or decrease the mortgage rate depending on market conditions.

For example, a 5/1 ARM means the interest rate is fixed for the first five years and then adjusts annually afterward.

Pros and cons of an adjustable-rate mortgage

Pros:

• Lower initial interest rates compared to fixed-rate mortgages
• Lower monthly payments during the fixed period
• Potential to save money if interest rates remain low

Cons:

• Rates and monthly payments can increase after the fixed period
• Uncertainty about long-term costs
• Not ideal for homeowners who plan to stay in the property for many years

Fixed vs. adjustable: which one is right for you?

Choosing between a fixed-rate mortgage and an adjustable-rate mortgage depends on several factors, including financial stability, risk tolerance, and long-term housing plans.

When a fixed-rate mortgage is better

• You plan to stay in your home for more than 10 years.
• You prefer stability and do not want to worry about rate changes.
• You expect interest rates to increase in the future.

When an adjustable-rate mortgage is better

• You plan to sell or refinance before the fixed period ends.
• You want lower initial payments and are comfortable with potential future rate increases.
• You expect interest rates to remain stable or decrease over time.

How to decide: key questions to ask before choosing

Before selecting a mortgage type, consider the following questions:

• How long do you plan to stay in the home? If you expect to move in a few years, an ARM may be a better option.
• Can you afford potential increases in payments? If an increase in interest rates would strain your budget, a fixed-rate mortgage is safer.
• Are you comfortable with financial risk? Fixed rates provide certainty, while ARMs require adaptability to market conditions.
• What is the current trend in mortgage rates? If rates are at historic lows, locking in a fixed rate might be more beneficial.

How interest rate changes impact mortgage choices

Mortgage rates fluctuate based on economic conditions, Federal Reserve policies, and overall market trends. Understanding how these changes impact fixed-rate and adjustable-rate mortgages can help borrowers make smarter financial decisions.

How rate increases affect borrowers

When interest rates rise, fixed-rate mortgages become more attractive because they lock in a stable rate before further increases. Borrowers who opt for an ARM during rising rate periods may face much higher payments after the initial fixed period.

For example, if you take out a 5/1 ARM at 5% and rates increase to 7% when your fixed term ends, your monthly payments could rise significantly depending on the remaining loan balance.

Borrowers most affected by rising rates:

• Those who plan to keep their mortgage long-term
• Homebuyers who do not plan to refinance
• Borrowers with tight budgets who cannot afford sudden increases

How falling rates create refinancing opportunities

When rates drop, homeowners with fixed-rate mortgages often choose to refinance to a lower rate, reducing their monthly payments or shortening their loan term. Borrowers with ARMs may benefit from rate decreases, but since adjustments happen periodically, they might not secure the lowest possible rate at the best time.

Strategies to lower your mortgage costs

Regardless of whether you choose a fixed-rate or adjustable-rate mortgage, there are several strategies to reduce the overall cost of your home loan.

1. Make extra payments

Paying more than the minimum mortgage payment can help you reduce the total interest paid over time. There are different ways to do this:

• Biweekly payments: Making payments every two weeks results in one extra mortgage payment per year, shortening your loan term.
• Lump-sum payments: Applying bonuses, tax refunds, or unexpected earnings toward your principal can reduce the balance faster.

2. Refinance when rates drop

If interest rates decrease, refinancing can help you secure a lower mortgage rate. Before refinancing, consider:

• Closing costs: Make sure the savings outweigh the costs of refinancing.
• Loan term adjustments: A shorter loan term can reduce overall interest expenses.

Use Fannie Mae’s refinancing guide to determine if refinancing is a good option for you.

3. Avoid private mortgage insurance (PMI)

PMI is typically required if your down payment is less than 20%. To eliminate PMI faster:

• Make extra principal payments to reach 20% equity sooner.
• Request PMI removal once your loan-to-value (LTV) ratio reaches 80%.
• Refinance if your home value increases, reducing your LTV ratio.

4. Shop around for better insurance and tax rates

Property taxes and homeowners insurance directly impact your mortgage payment. Some ways to reduce these costs include:

• Appeal your property tax assessment if your home is overvalued.
• Compare homeowners insurance policies for better rates.
• Bundle home and auto insurance for discounts.
