Mortgage Rates Explained: What Determines Your Rate and How to Compare Offers

Fixed vs. Variable Rates: Key Differences

When shopping for a mortgage, one of the first decisions is choosing between a fixed-rate mortgage and an adjustable-rate mortgage (ARM). Each has distinct characteristics that affect your monthly payment and long-term cost.

A fixed-rate mortgage has an interest rate and monthly principal and interest payment that stay the same for the entire loan term. However, the total monthly payment can still change if property taxes, homeowner's insurance, or mortgage insurance changes. Most borrowers choose fixed-rate mortgages.

An adjustable-rate mortgage (ARM) has an introductory period with a fixed rate, after which the rate can adjust up or down based on market conditions. ARMs have rate caps that limit how much the interest rate can adjust. They offer a lower initial interest rate compared to fixed-rate mortgages, but they offer less predictability and could be cheaper only in the short term.

• Fixed-rate: predictable payments, but initial rate typically higher.
• ARM: lower initial rate, but payments may change after the intro period.

Factors That Influence Your Mortgage Rate

Lenders consider several factors when setting mortgage rates, and understanding them can help you position yourself for a better rate.

Credit score is a major factor. A higher credit score typically results in a lower rate. A larger down payment also typically results in a lower rate because it reduces the lender's risk.

The loan type matters too. FHA and VA loans often have lower rates than conventional loans, partly because they are government-backed and may have more lenient credit requirements. Loan term, loan amount, location, occupancy, and property type also influence the rate you are offered.

• Credit score: higher scores generally receive better rates.
• Down payment: larger down payments typically lead to lower rates.
• Loan type: government-backed loans often have lower rates.
• Loan term: shorter terms (e.g., 15-year) typically have lower rates than longer terms.
• Other factors: loan amount, location, occupancy, and property type.

How to Read a Mortgage Rate Quote: APR vs. Interest Rate

When you receive a mortgage rate quote, you'll see both an interest rate and an annual percentage rate (APR). They represent different costs.

The interest rate is the cost of borrowing the principal, expressed as a percentage. The APR includes the interest rate plus certain fees and costs associated with the loan, giving you a more complete picture of the loan's total cost. For example, a 30-year fixed-rate quote might show an interest rate of 6.625% and an APR of 6.804%.

When comparing offers, it is important to look at both numbers. The APR can help you compare loans with different fees, but the interest rate determines your monthly principal and interest payment.

• Interest rate: the base cost of borrowing.
• APR: includes interest plus certain fees, providing a fuller cost comparison.

Current Rate Environment: Understanding Market Trends

Mortgage rates are influenced by the Federal Reserve's monetary policy, but they do not always move in sync with the federal funds rate. Changes in the economy, inflation, and investor sentiment all play a role.

As of August 2026, Zillow Home Loans reported the following rates: a 30-year fixed at 6.625% (APR 6.804%), a 15-year fixed at 6.000% (APR 6.308%), and a 7-year ARM at 6.625% (APR 6.696%). These figures illustrate the variety of rates available by loan type and term.

It's important to remember that these rates are a snapshot from one lender on a specific date. Rates change frequently, and your personal rate will depend on your financial profile and market conditions.

How to Compare Mortgage Offers from Different Lenders

Comparing mortgage offers from different lenders is essential to find the best rate and terms for your situation. While the interest rate is a key factor, it's not the only one. You should compare official Loan Estimates from multiple lenders to understand the full cost of a mortgage.

Loan Estimates include the interest rate, APR, monthly payment, and closing costs. By reviewing these documents side by side, you can identify which lender offers the best overall value.

When comparing, consider the loan term, whether the rate is fixed or adjustable, any discount points, and the lender's fees. A lower interest rate with high fees may cost more in the long run than a slightly higher rate with lower fees.

• Request Loan Estimates from at least three lenders.
• Compare interest rate, APR, monthly payment, and closing costs.
• Consider the loan term and type (fixed vs. ARM).
• Evaluate discount points and other fees.

How to Lock in a Mortgage Rate

A mortgage rate lock guarantees an interest rate for a specified period, protecting you from rate increases while your loan is being processed. Rate locks can be obtained from your lender and may involve fees or costs.

The length of a rate lock can vary, commonly ranging from 30 to 60 days, but longer locks may be available. When you lock a rate, you are securing that rate even if market rates rise before closing. However, if rates fall, you are still obligated to the locked rate.

It's important to discuss rate lock options with your lender early in the process to understand any associated costs and the duration of the lock.

• Rate locks guarantee a specific interest rate for a set period.
• They often involve costs, so evaluate whether the lock is worth the fee.
• Common lock periods are 30 to 60 days, but longer options may exist.

Factors Driving Rate Changes

Mortgage rates do not just change randomly; they are driven by economic indicators and monetary policy. Here are key factors:

Inflation and the Federal Reserve's response are major drivers. When inflation is high, the Fed may raise the federal funds rate, which influences borrowing costs across the economy, including mortgages. However, the correlation is not direct.

Other factors include employment data, economic growth, global market conditions, and investor demand for mortgage-backed securities. Lenders also adjust rates based on their business costs and competition.

• Federal Reserve monetary policy
• Inflation and economic growth
• Employment data
• Investor demand for mortgage-backed securities

How to Get Personalized Quotes

The rates shown are general examples. To get a rate tailored to your situation, you need to apply for preapproval or request quotes from multiple lenders.

When you contact lenders, they will evaluate your credit score, income, down payment, and other factors to provide a personalized rate quote. Providing accurate information and shopping around can help you secure the best rate.

Remember to compare official Loan Estimates, not just advertised rates, to understand the full cost of the loan.

• Check your credit score before applying.
• Gather financial documents (income, assets, etc.).
• Shop around with at least three lenders.
• Compare Loan Estimates side-by-side.

Side-by-side category and decision criteria

This table compares the key characteristics of fixed-rate and adjustable-rate mortgages to help you choose the right type for your needs.

Consider the following decision criteria when choosing between a fixed and adjustable rate: your expected length of stay in the home, your tolerance for payment variability, and current market conditions. A fixed-rate mortgage may be preferable if you plan to stay long-term and value predictable payments. An ARM might be attractive if you expect to move or refinance before the adjustment period, and if you can manage potential payment increases.

• Decision criteria: length of stay, payment predictability, risk tolerance.
• Fixed-rate: best for long-term stability.
• ARM: may be cheaper in the short term, but payments can rise.
