Buying a home is a significant milestone, and that's true whether you're getting your first place or ready to settle into your “forever home.” There are several financial factors to remember as you prepare for the transaction. For instance, you'll have to get your down payment in order, and you'll need to estimate your new monthly payment to make sure it's one you can afford.

Current mortgage rates will impact your payment dramatically, as will the amount you plan to borrow and the type and duration of the home loan you choose. Here’s what you need to know about how mortgage rates are determined, which factors influence whether they go up or down and how you can qualify for the best mortgage rates out there.

What is a mortgage rate?

A mortgage rate is the interest charged by a lender on a home loan. When you borrow money to buy a home, you agree to repay the amount you borrow (the principal) along with a percentage of that amount as interest. The mortgage rate determines how much interest you'll pay over the life of the loan and directly impacts your monthly payment.

Mortgage rates are typically expressed as an annual percentage rate (APR), which includes both the interest rate and any lender fees or other costs. Rates can be fixed, meaning they stay the same throughout the loan term, or adjustable, meaning they fluctuate after an initial fixed period based on market conditions.

Understanding how mortgage rates work is essential for homebuyers because even a small difference in the rate can translate into thousands of dollars in savings or additional costs over the life of the loan. Factors that influence mortgage rates include personal creditworthiness, economic conditions and lender-specific policies.

How mortgage rates are set in the market

Mortgage rates are largely shaped by broader market forces, particularly the bond market. Mortgage lenders typically base their rates on the yield of 10-year U.S. Treasury bonds, which are considered a benchmark for long-term interest rates. When Treasury yields go up, mortgage rates usually follow.

Lenders also consider the costs associated with bundling and selling mortgages on the secondary market. These mortgage-backed securities (MBS) are traded among investors, and the demand for MBS can affect the rates that lenders offer. If demand is high, lenders may offer lower rates to remain competitive. If demand is low, rates might rise to compensate for reduced investor interest.

Other contributing factors include inflation expectations, economic outlooks and risk premiums lenders build into their pricing models. In volatile or uncertain times, lenders may raise rates slightly to guard against potential losses. These external dynamics, combined with personal borrower factors, help determine the final rate a homebuyer sees.

Personal factors that affect mortgage rates

A range of personal factors concerning your household finances and the home you're buying will impact the mortgage rates you get. These factors include your overall credit health and the financial position you're in when you're ready to buy a home.

Borrowers considered to be a low risk to their lenders receive better mortgage rates than those who appear to have a higher chance of defaulting. Here's a rundown of various personal factors that impact mortgage rates.

Credit score
Your credit score gives lenders a glimpse into your creditworthiness, i.e., how likely you are to repay a loan based on your borrowing history. Those with higher credit scores are less likely to default on loans, so they tend to receive the lowest interest rates from lenders.

Fannie Mae and Freddie Mac revamped their home mortgage pricing grids in May 2023. Based on the new pricing matrix for home purchase loans, individuals with a credit score of 780 or higher are positioned to get the lowest mortgage rates overall.

Down payment
A down payment made on a home purchase can also be linked to default risk. And if you make a down payment of at least 20% of your home's purchase price, you can avoid paying private mortgage insurance (PMI).

Fannie Mae and Freddie Mac's changes that took effect in May 2023 allow some individuals with lower down payment amounts to pay lower mortgage fees than those who put down 20% or more. The Urban Institute notes that, while this may seem counterintuitive, the lower mortgage fees for borrowers making lower down payments are likely tied to the obligation these borrowers have to pay PMI, which protects lenders from default.

Loan-to-value ratio
Your down payment also helps lenders compute your loan-to-value (LTV) ratio, another factor influencing mortgage rates. Underwriters use LTV to assess the risk of a loan. LTV is calculated by dividing the mortgage amount by the appraised home value, and it reflects the portion of the appraised value not covered by the down payment.
Debt-to-income ratio
Debt-to-income (DTI) ratio is a metric determined by taking all your monthly debt payments and dividing them by your gross monthly income. For example, if your combined monthly debt payments amount to $3,000 and your gross monthly income is $7,000, your DTI is around 43% (3,000 / 7,000 = 0.4286).

DTI impacts mortgage rates because borrowers with more debt are seen as a higher risk. The maximum DTI accepted for a mortgage varies by mortgage type and lender, but most conventional mortgages will require a DTI of 50% or less.

Loan term
Your loan term can also play a significant role in mortgage rates. Loans with longer terms (like 30-year loans) typically have higher interest rates than loans with shorter terms. However, the monthly payment will be higher for a mortgage with a shorter term, as the mortgage must be paid off in less time.
Fixed vs. adjustable rates
Some lenders offer both fixed- and adjustable-rate mortgages. A fixed-rate mortgage has an interest rate that stays the same throughout its term. The interest rate for an adjustable-rate mortgage, on the other hand, fluctuates. An adjustable-rate mortgage’s initial rate stays the same for an initial period (often five to seven years), and then it may change on a yearly or even monthly basis. There are pros and cons to both types of rates.
Property use
Christina McCollum, a Washington state-based mortgage expert at Churchill Mortgage, says that mortgage rates are heavily influenced by how the homebuyer plans to use the property. Will it be a primary home, a secondary home or an investment property?

Mortgage rates and fees for buyers investing in a primary home are generally lower than for buyers seeking vacation homes or investment properties.

Location
The Consumer Financial Protection Bureau (CFPB) notes that where your home is located can impact mortgage rates. You may pay a higher rate in some parts of the country than others, depending on whether you’re buying in an urban or rural location, whether the area has a high or low rate of defaults on mortgages, etc.
Loan type
Finally, the type of mortgage you get approved for will play a role in the mortgage rate you qualify for. For example, rates offered for conventional mortgages may differ from rates offered for mortgages guaranteed by a federal body, like the U.S. Department of Agriculture (USDA).

The CFPB says this fact underscores the importance of shopping around among lenders and mortgage types to find the best deal.

External factors that affect mortgage rates

A range of economic factors beyond a homebuyer's control will impact the rates they qualify for. These external factors heavily influence the amount of interest homebuyers have to pay.

The Federal Reserve

The Federal Reserve (“the Fed”) doesn't set mortgage rates directly, but it does set the federal funds rate — or the rate banks pay to borrow money from one another. Ultimately, this rate influences the interest rates consumers pay each time they borrow money, whether through credit cards, personal loans, mortgages or other forms of credit.

The Fed raised the federal funds rate many times throughout 2022 to 2025, leading to a dramatic rise in mortgage rates over the last few years. In fact, Freddie Mac figures show the average 30-year fixed mortgage rate increased from 2.65% on Jan. 7, 2021, to 6.72% on July 16, 2025.

Economy

Mortgage broker Joseph Melara of Residential Brokers in Palm Desert, California, emphasizes that the economy is another factor that influences mortgage rates. Inflation, employment rates and GDP growth affect rates for all homebuyers.

"When the economy is strong, mortgage rates tend to rise, while during periods of economic uncertainty or recession, rates tend to decrease," he said.

Melara says the supply and demand dynamics of the mortgage market can also affect rates.

"High demand for mortgages can lead to higher rates, while lower demand can result in lower rates," he said. "Similarly, the availability of funds for lending, determined by factors like investor appetite for mortgage-backed securities, can influence rates."

Points and lender credits

Finally, Melara says points can impact mortgage rates. The term "points" refers to upfront fees paid to the lender at closing, with each point representing 1% of the loan amount.

"By paying points, borrowers can lower their mortgage rate," Melara said.

Conversely, lenders may offer lender credits toward closing costs in exchange for a higher interest rate.

"It's important for borrowers to evaluate the cost and benefits of paying points or accepting lender credits based on their specific financial goals and circumstances," he said.

Since the availability of points and lender credits can vary across mortgage lenders, this is still considered an external factor that influences mortgage rates.

How to estimate your mortgage rate

If you're curious about the mortgage rate you'll pay and your new home's monthly payment, several steps can help you get rough estimates. For example, you can use an online mortgage calculator to calculate your new home payment using current mortgage rates. You can also contact a few lenders to see what rates they're offering most buyers who apply and which eligibility requirements you'll need to meet to qualify.

Some of the best mortgage lenders may allow you to lock in your rate as early as preapproval; others won’t offer a rate lock until after you're formally approved for a home loan. But every lender should be able to give you a ballpark figure of its rates if you simply call in or inquire about rates online.

FAQ

What is a good mortgage rate?

Mortgage rates fluctuate based on economic conditions, so the standard for a “good” mortgage rate varies over time. It can also vary based on a borrower’s credit score, down payment amount and other factors.

A homebuyer can make sure they're getting a good mortgage rate by shopping around across multiple lenders and comparing offers.

Can I negotiate a mortgage rate?

Homebuyers may be able to get a lower mortgage rate by paying points upfront and shopping around among lenders to find the best deal. Take the lowest rate you’re offered and ask your preferred lender for a rate match.

Are mortgage rates the same for all lenders?

Mortgage rates are not the same for all lenders. Different lenders can offer slightly different mortgage rates, which is another reason you'll want to compare lenders and loan offers before you move forward with a home purchase.

Bottom line

Your ability to obtain a low mortgage rate can depend on a host of factors, and not all of them are within your control. However, you can typically get a better mortgage rate if you work on improving your credit score and take the time to compare the types of mortgages and the lenders that offer them.

You may also be able to score a lower mortgage rate if you pay points on your mortgage upfront. Whatever you do, take the time to speak with at least a few mortgage companies to find out which moves could help you get a better deal overall.
