What Affects Mortgage Rates?

Key Takeaways

  • Mortgage rates are shaped by both market conditions and borrower-specific loan details.
  • Inflation, economic growth, and housing demand can raise or lower rates across the market.
  • Higher credit scores and larger down payments often help borrowers qualify for lower rates.
  • Loan structure, including term, fixed vs. adjustable rate, and loan type, can affect mortgage pricing.

Mortgage rates are influenced by two broad categories of factors: market-wide conditions that affect mortgage pricing across the economy, and borrower-specific factors that affect the rate quote you may personally receive.

Market forces such as inflation, economic growth, and housing demand can push mortgage rates up or down more broadly. At the same time, lenders also price loans based on the details of your application, such as your credit profile, down payment, loan structure, and the property you are financing.

Understanding both sides of the equation can help you make better borrowing decisions and focus on the factors you may be able to improve before applying.

Inflation

Inflation refers to the increase in the price level of an economy over a certain time period. As the general price level increases, every unit of currency is able to purchase fewer goods and services.

This upward movement of prices as a result of inflation reflects the state of the overall economy and is a crucial factor for mortgage lenders, since inflation weakens the purchasing power of dollars. Lenders must keep interest rates at a level that is enough so that their returns allow them to realize a profit.

For instance, if the home mortgage rate today is 4% but the annual inflation level is 2%, the return on a mortgage when it comes to the purchasing power of the dollars the mortgage lender gets in return will be 2%. For this reason, mortgage lenders always keep tabs on the inflation rate and make adjustments to their rates as necessary.

Economic Growth

The condition of the economy will impact home mortgage rates. Certain indicators dictate how well the economy is growing, such as the employment rate, which will, in turn, impact home mortgage interest rates.

A healthy economy that’s growing at a healthy rate will typically come with higher wages, more jobs, and great consumer spending. And with increased consumer spending comes an increased demand for mortgages.

This is a good thing for the economy of a nation. That said, home mortgage interest rates in this situation will typically increase, which will make homebuying more expensive.

The opposite is also true: a sluggish economy where wages are stagnant and consumer spending is weak means the demand for mortgages will also lag. In turn, home mortgage rates will likely stall.

Real Estate Market Conditions

The temperature of the housing market is another important factor that influences home mortgage rates. A weak market is usually characterized by lower demand for housing from buyers. With a drop in demand for housing also comes a decline in demand for mortgages. In this case, home mortgage interest rates are pushed downward.

On the other hand, a hot housing market that sees great demand for housing will help to push rates upward, as long as all other economic factors align. These conditions impact the levels that mortgage lenders set their mortgage rates.

Which Mortgage Rate Factors Can You Control?

Some mortgage rate drivers are outside your control, including inflation, broader economic conditions, and overall real estate market activity. These factors influence rate levels across the market, and individual borrowers cannot change them.

What you can often influence is the rate quote tied to your own application. In practice, that usually means improving your credit profile, increasing your down payment where possible, choosing a loan structure that fits your goals and risk tolerance, and comparing quotes from lenders before you lock. Even when market rates are elevated, these borrower-controlled decisions can still affect the pricing you are offered.

Your Credit Score

While you may be unable to control what the economy or local housing market is doing, you do have control over other factors that could have an effect on your home mortgage rate. One important factor is your credit score.

Generally speaking, borrowers with a higher credit score can often get a lower interest rate on their mortgages than borrowers with a lower credit score. Mortgage lenders use credit scores as one way to assess a person’s ability to maintain a mortgage.

Lower scores mean the consumer likely has a past of poor financial management, including late or missed bill payments. In this case, the borrower will be considered a higher risk to the lender, who will charge a higher interest rate in order to offset this risk.

Higher scores, on the other hand, usually mean that the borrower has been able to successfully manage their finances, including paying their bills on time. These lower-risk borrowers will then be rewarded with a lower home mortgage interest rate from their lender.

Before you apply for a home loan, consider pulling your credit report, which will identify your credit score and any other pertinent information that’s affecting it. If you notice any details that are noted in error, it’s important to have them investigated and rectified right away, as they could be negatively affecting your credit score.

If your credit score is a little on the low end, take steps to improve it by doing the following:

  • Pay all bills on time and in full
  • Don’t spend any more than 30% of your credit card limit
  • Don’t open too many credit accounts within a short time span
  • Don’t close any old credit accounts, even if you don’t use them

Property Location

The location of the home you wish to buy will also have some effect on the type of home mortgage rate you’re given by your lender. Depending on exactly what state or city you’re buying in, your lender may offer you a slightly different rate.

The home mortgage rate differs among various states for a few reasons. For instance, mortgage default risk plays a role, which refers to the share of borrowers who fail to pay back their mortgages. Early repayment risk is also a factor, which involves the number of borrowers who sell or refinance before the lender is able to see a profit. Further, state laws may also affect a mortgage lender’s ability to foreclose.

Mortgage Loan Amount

Your loan amount can affect mortgage pricing, but lenders do not look at loan size in isolation. They also consider how that amount relates to the home’s value, which is measured by your loan-to-value ratio (LTV).

In many cases, LTV is the more direct risk factor. A higher LTV means the lender is financing more of the purchase price and you are contributing less upfront, which generally increases risk from the lender’s perspective. So, an LTV of 95% will typically be considered riskier than an LTV of 80%.

Loan amount can also matter because it may affect the loan category. Loans above the applicable conforming loan limit are known as jumbo loans. That does not automatically mean the rate will always be higher simply because the balance is larger. In practice, pricing can vary by product type, lender appetite, and whether the loan is conforming or jumbo.

Down Payment

Generally speaking, a larger down payment usually translates into a lower interest rate. That’s because mortgage lenders view borrowers as less of a risk when the borrower has more of a stake in the property.

The higher your down payment, the more of a risk you’re taking, and the less risk the lender is assuming. As a reward, lenders will offer lower interest rates because they are not taking on as much risk.

Overall, the larger the down payment, the lower the cost to borrow, especially if you can snag a lower home mortgage rate.

Mortgage Term

The term of your mortgage refers to the amount of time you have before your mortgage is due for full repayment. So, if you have a 30-year term, that means you have 30 years to pay off what you owe, including interest.

In general, shorter-term mortgages often have lower interest rates and lower total borrowing costs, but their monthly payments are higher because the balance is repaid over fewer years. Longer-term mortgages often have higher rates than shorter-term options, but they spread repayment out over a longer period, which can make monthly payments more manageable.

Choosing a mortgage term is usually a tradeoff between monthly affordability and total interest cost over time. Borrowers who want lower payments may prefer a longer term, while those who can handle a higher monthly payment may prioritize paying less interest overall.

Mortgage Rate Type

When you take out a mortgage, your interest rate will be classified as one of two types: fixed or adjustable. With a fixed interest rate, your rate will not change over the term of your mortgage. That means your principal and interest payment is more predictable over time.

An adjustable-rate mortgage (ARM) is a type of loan for which the interest rate can change, usually in relation to an index interest rate. These loans may have a fixed-rate period at the beginning, after which the rate can adjust up or down based on the loan terms.

Borrowers who are planning to move, sell, or refinance before the initial fixed-rate period expires may find adjustable-rate mortgages appealing because they may offer a lower introductory rate. Borrowers who expect to keep the home longer may prefer the stability of a fixed-rate mortgage, especially if payment certainty is a top priority.

Mortgage Type

There are many different mortgage types to choose from, and each one is best suited for different types of borrowers, such as the following:

The mortgage interest rates that come with each mortgage type may differ somewhat, which is why it’s important to do some homework on the various loan types and the rates that come with each before choosing which loan to apply for.

FAQs

What affects mortgage rates?

Mortgage rates are influenced by both market-wide conditions and borrower-specific factors. Broad factors include inflation, economic growth, and housing market conditions, while personal pricing factors can include your credit score, down payment, loan-to-value ratio, mortgage term, rate type, loan type, loan amount, and the property location.

What affects mortgage rates the most?

There is not one single factor that always matters most in every situation. Market rates are heavily influenced by broader conditions such as inflation and economic growth, while the rate a specific borrower receives is often strongly affected by credit profile, down payment, loan structure, and overall risk to the lender.

What causes mortgage rates to go down?

Mortgage rates may move down when inflation eases, economic activity slows, or housing demand softens. Lower demand for mortgages can also contribute to lower rates, although lenders still price each loan based on the borrower’s individual profile.

How are 30-year mortgage rates determined?

30-year mortgage rates are determined by a mix of market conditions and loan-specific risk. Lenders consider broad forces such as inflation and the economy, then adjust pricing based on factors like credit score, down payment, loan-to-value ratio, property location, and whether the loan is fixed-rate or adjustable.

How does my credit score affect my mortgage interest rate?

A higher credit score often helps borrowers qualify for a lower mortgage rate because lenders may view them as lower risk. A lower credit score can lead to a higher rate if the lender believes there is a greater chance of missed payments or other repayment problems.

Can I lower my mortgage rate before applying?

You may be able to improve the rate you are offered by strengthening the parts of the application you can control. Common steps include improving your credit profile, correcting errors on your credit report, increasing your down payment if possible, choosing a loan structure that fits your goals, and comparing quotes from multiple lenders.

Does a bigger down payment always get you a lower rate?

A larger down payment usually helps because it lowers the lender’s risk and reduces the loan-to-value ratio. It does not guarantee a lower rate in every case, but it often improves pricing compared with a smaller down payment.

Does property location affect mortgage rates?

Yes, property location can affect mortgage pricing. Lenders may price loans differently by state or city based on factors such as mortgage default risk, early repayment risk, and state laws that can affect foreclosure processes.

Are fixed-rate or adjustable-rate mortgages better when rates are high?

The better choice depends on your plans and comfort with risk. Adjustable-rate mortgages may offer a lower introductory rate and can appeal to borrowers who expect to move, sell, or refinance before the fixed period ends. Fixed-rate mortgages may be a better fit for borrowers who want long-term payment stability and expect to keep the home longer.

Does the loan amount affect mortgage rates?

Loan amount can affect pricing, but lenders usually look closely at how the loan amount compares with the home’s value through the loan-to-value ratio. Pricing can also vary depending on whether the loan falls into a conforming or jumbo category, as well as the lender’s product guidelines and appetite.
