At IC Credit Union, our mission is to equip you with the financial knowledge you need to make informed decisions. In this installment of our financial education series, we’re focusing on interest rates—specifically, mortgage rates. Whether you’re a first-time homebuyer or considering refinancing, understanding how interest rates work can help you navigate the mortgage process with confidence.

What is An Interest Rate

An interest rate is the cost of borrowing money, expressed as a percentage of the loan amount. When you take out a loan, such as a mortgage, the lender charges interest on the money you borrow. The interest rate determines how much you’ll pay in addition to repaying the principal, or the original amount of the loan.

How Do Mortgage Interest Rates Work?

Mortgage rates are the interest rates applied to home loans. These rates can significantly impact the total cost of your mortgage and your monthly payments. Mortgage interest rates are influenced by various factors, including:

1. Economic Conditions: Mortgage rates tend to rise and fall based on broader economic trends, such as inflation, employment rates, and the Federal Reserve’s monetary policy. When the economy is strong, rates may rise; during economic downturns, rates often fall.
2. Loan Term: The term of your mortgage—how long you have to repay the loan—affects the interest rate. Generally, shorter-term loans (like 15-year mortgages) come with lower interest rates than longer-term loans (like 30-year mortgages) because the lender’s risk is reduced.
3. Loan Type: There are different types of mortgages, including fixed-rate and adjustable-rate mortgages (ARMs). Fixed-rate mortgages have a consistent interest rate for the life of the loan, providing stability in your monthly payments. ARMs, on the other hand, have an interest rate that may start lower than a fixed-rate mortgage but can change periodically based on market conditions, which could increase your payments over time.
4. Your Credit Score: Your credit score plays a significant role in determining the interest rate you qualify for. Borrowers with higher credit scores are typically offered lower rates because they are seen as less risky by lender
5. Down Payment: The size of your down payment can also affect your mortgage rate. A larger down payment reduces the lender’s risk, which may result in a lower interest rate.
6. Loan Amount and Loan-to-Value Ratio (LTV): The LTV ratio, which compares the loan amount to the appraised value of the home, is another key factor. A lower LTV (meaning a larger down payment) generally leads to a lower interest rate.

Types of Mortgage Interest Rates

1. Fixed-Rate Mortgage: With a fixed-rate mortgage, your interest rate remains the same for the entire loan term, whether it’s 15, 20, or 30 years. This consistency means your monthly payments remain stable, making it easier to budget over the long term.
2. Adjustable-Rate Mortgage (ARM):  An ARM typically starts with a lower interest rate than a fixed-rate mortgage, but the rate is subject to change at specified intervals, usually after an initial fixed period (e.g., 5, 7, or 10 years). After this period, the rate adjusts based on market conditions, which can lead to fluctuating monthly payments.
3. Interest-Only Mortgage: An interest-only mortgage allows you to pay just the interest on the loan for a certain period, typically 5-10 years. After this period, you begin paying both principal and interest, often resulting in significantly higher payments. While this option can lower initial payments, it may cost more in the long run.
4. Jumbo Loans:  Jumbo loans are mortgages that exceed the conforming loan limits set by Fannie Mae and Freddie Mac. Because they involve larger sums of money, they often come with higher interest rates and stricter qualification requirements.

How Mortgage Interest Rates Impact Your Finances

1. Monthly Payments: The interest rate directly affects your monthly mortgage payment. Even a small difference in rates can result in significant changes to your monthly costs and the total amount paid over the life of the loan.
2. Total Interest Paid: The interest rate determines how much you’ll pay in interest over the life of the mortgage. A lower rate means less money paid in interest, potentially saving you thousands of dollars.
3. Affordability: Lower interest rates increase your purchasing power, allowing you to afford a more expensive home while keeping payments within your budget. Conversely, higher rates may limit the amount you can borrow.
4. Refinancing Opportunities: If interest rates drop after you’ve secured a mortgage, refinancing might allow you to lock in a lower rate, reducing your monthly payments and total interest costs. However, refinancing comes with its own costs, so it’s important to weigh the benefits against the expenses.

Tips for Securing a Lower Mortgage Rate

1. Improve Your Credit Score:  Before applying for a mortgage, work on boosting your credit score by paying bills on time, reducing debt, and avoiding new credit inquiries.
2. Save for a Larger Down Payment: A larger down payment reduces your LTV ratio and can help you secure a lower interest rate.
3. Shop Around: Don’t settle for the first mortgage offer you receive. Compare rates from multiple lenders to find the best deal. Consider working with a mortgage broker who can help you navigate different options.
4. Consider Points: You can lower your interest rate by purchasing discount points, which are upfront payments to the lender. Each point typically costs 1% of the loan amount and can reduce the interest rate by about 0.25%. This can be beneficial if you plan to stay in your home for a long time.
5. Lock in Your Rate: Once you find a rate you’re comfortable with, consider locking it in with your lender to protect yourself from potential rate increases before closing on your home.
