How Credit Scores Affect Your Mortgage Rate
Updated: Aug 20
When you're preparing to buy a home, even a small difference in your mortgage interest rate can make a meaningful difference in your monthly payment and the amount of interest you pay over the life of the loan.
One of the factors lenders consider when determining the mortgage rate available to you is your credit score.
Generally, a stronger credit profile can help you qualify for more favorable mortgage terms. But your credit score isn't the only factor that determines your rate—and having less-than-perfect credit doesn't necessarily mean you can't buy a home.
Understanding how credit scores affect mortgage rates can help you make better decisions before you apply for financing.

What Is a Credit Score?
A credit score is a numerical representation of information contained in your credit history. It helps lenders evaluate the likelihood that a borrower will repay debt as agreed.
One of the most commonly recognized scoring models is FICO®, although lenders may use particular scoring models and procedures when evaluating mortgage applications.
Credit scores are generally influenced by factors including:
Payment history
Amounts owed and credit utilization
Length of credit history
Types of credit accounts
Recent applications and new credit
Your credit report and credit score are related, but they're not the same thing. Your credit report contains information about your credit history, while a credit score uses information from that report to generate a numerical assessment of credit risk.
Why Does Your Credit Score Affect Your Mortgage Rate?
From a lender's perspective, every mortgage involves risk.
The lender is providing a substantial amount of money today based on your commitment to repay it over many years. Your credit history provides information about how you've managed financial obligations in the past.
A stronger credit profile generally represents lower perceived credit risk. Depending on the loan program and other factors, this may help a borrower receive more favorable mortgage pricing.
A lower credit score may represent greater perceived risk and can potentially result in a higher interest rate, additional costs, different loan terms, or fewer available financing options.
However, it's important to understand that there isn't a simple formula such as:
"A 720 score gets X rate and a 680 score gets Y rate."
Mortgage rates change continually, and credit score is only one component of mortgage pricing.
Credit Score Isn't the Only Factor Affecting Your Mortgage Rate
Two borrowers with identical credit scores don't necessarily receive identical mortgage rates.
That's because lenders evaluate several characteristics of the transaction.
Your Down Payment and Loan-to-Value Ratio
The amount you borrow compared with the property's value can influence your mortgage pricing.
A larger down payment reduces the percentage of the property's value being financed and may affect both the available loan terms and whether mortgage insurance is required.
The Type of Mortgage
Different loan programs have different pricing structures and qualification guidelines.
A borrower considering a Conventional Loan, for example, may see credit score affect pricing differently than someone obtaining an FHA, VA, or USDA loan.
This is one reason comparing loan programs can sometimes be more valuable than simply asking, "What's today's mortgage rate?"
The Loan Term
A 15-year mortgage and a 30-year mortgage don't necessarily carry the same interest rate.
The appropriate term depends on your priorities, including monthly payment, cash flow, and how quickly you want to repay the loan.
The Property and Its Intended Use
Whether you're purchasing a primary residence, second home, or investment property can affect mortgage pricing and program availability.
The Type of Interest Rate
Fixed-rate and adjustable-rate mortgages have different structures and can be priced differently.
Current Financial Markets
Mortgage rates are also influenced by broader economic and financial-market conditions.
That means improving your credit score doesn't guarantee that overall market rates will be lower by the time you're ready to purchase. It can, however, potentially improve your position relative to the financing available at that time.
How Much Difference Can a Mortgage Rate Make?
This is where credit and mortgage pricing become particularly important.
A difference in interest rate that looks small on paper can become significant because a mortgage involves a large amount of money financed over a long period.
Consider a hypothetical $300,000, 30-year fixed-rate mortgage.
At a hypothetical 6.00% interest rate, the monthly principal and interest payment would be approximately $1,799.
At 6.50%, that payment would be approximately $1,896.
That's a difference of roughly $97 per month, or more than $1,100 per year.
Over many years, the difference can become substantial.
These figures are only illustrative and exclude taxes, insurance, mortgage insurance, HOA fees, closing costs, and other potential expenses. They are not a quote or representation of currently available mortgage rates.
The point is simple:
Your mortgage rate matters, and improving the financial factors within your control before applying can potentially have long-term value.
What Credit Score Do You Need to Buy a Home?
There is no single minimum credit score that applies to every mortgage.
Different loan programs have different requirements, and individual lenders may establish additional guidelines.
Conventional Loans
Conventional financing generally places significant emphasis on a borrower's credit profile. A stronger score may improve both program availability and mortgage pricing.
FHA Loans
FHA financing offers more flexible credit guidelines than many conventional mortgage programs and can provide an alternative for borrowers whose credit profiles make conventional financing more challenging.
VA Loans
Eligible Veterans, active-duty service members, and certain surviving spouses may have access to VA financing, which uses its own underwriting guidelines and can offer significant benefits to qualified borrowers.
USDA Loans
USDA financing also has specific borrower and lender requirements. Eligible borrowers purchasing qualifying properties may have access to competitive government-backed financing.
Rather than assuming your credit score automatically qualifies or disqualifies you, speak with a mortgage professional who can evaluate your broader financial picture and available loan programs.
Can You Get a Mortgage With Less-Than-Perfect Credit?
Potentially, yes.
One of the biggest mistakes prospective homebuyers make is assuming they shouldn't even speak with a mortgage professional until their credit is "perfect."
There is no such requirement.
A lower credit score can affect the programs, rates, or terms available to you, but credit is only one part of your overall mortgage application.
Depending on your circumstances, you may already qualify for certain financing options.
And if you're not currently in the position you need to be, understanding why can give you a clearer idea of what you may want to work on before purchasing a home.
How Can You Improve Your Credit Before Applying for a Mortgage?
If buying a home is part of your plans, giving yourself time to prepare can be beneficial.
Pay Your Bills on Time
Payment history is an important component of many credit-scoring models. Consistently making required payments on time can help you maintain a stronger credit profile.
Reduce Credit Card Balances
Your revolving credit utilization—the amount of available revolving credit you're currently using—can influence your credit score.
Paying down credit card balances may help improve this aspect of your credit profile.
Review Your Credit Reports
Reviewing your credit reports before applying for a mortgage gives you an opportunity to understand what's being reported and identify information you believe may be inaccurate.
If you find an error, you can use the appropriate credit-reporting agency's dispute process.
Be Careful About Opening New Accounts
Applying for several new credit accounts shortly before obtaining a mortgage can affect your credit profile and may also add new monthly obligations.
If you're preparing to purchase a home, discuss major financing decisions with your mortgage professional.
Don't Close Accounts Just to "Clean Up" Your Credit
Closing an older credit account isn't automatically beneficial and can sometimes affect factors used in calculating credit scores.
Credit decisions should be made based on your overall financial situation rather than assumptions about what will immediately increase a score.
Don't Try to "Fix" Your Credit at the Last Minute
If you're thinking about buying a home in the next several months, it's usually better to understand your credit situation before you've found the house you want.
Why?
Because some improvements take time.
Discovering a credit issue while you're already negotiating a purchase can leave you with fewer options and more pressure.
Starting the conversation earlier gives you time to understand your financing position and make informed decisions.
Credit Score vs. Financial Readiness
A high credit score doesn't automatically mean you're financially ready to purchase a home.
Likewise, a less-than-perfect credit score doesn't automatically mean you aren't.
Mortgage lenders consider a broader financial picture that can include income, employment, debts, assets, down payment, property characteristics, loan program, and other factors.
And beyond lender qualification, you should consider your own financial comfort.
The objective isn't simply to qualify for the largest mortgage possible.
It's to find financing that makes sense for the home you want and the financial life you want to maintain after buying it.
Frequently Asked Questions About Credit Scores and Mortgage Rates
Does a higher credit score guarantee a lower mortgage rate?
No. A stronger credit score can potentially help you obtain more favorable mortgage pricing, but your interest rate depends on multiple factors, including the loan program, down payment, property, loan term, market conditions, and other characteristics of the transaction.
Will checking my own credit score hurt my credit?
Checking your own credit is generally considered a soft inquiry and does not affect your credit score. A lender's credit inquiry during a mortgage application may be treated differently.
Should I improve my credit before applying for a mortgage?
It depends on your situation. Improving your credit profile may potentially expand your financing options or improve available terms, but you shouldn't automatically assume you need to delay purchasing a home. A mortgage professional can help you understand where you currently stand.
Can I get an FHA loan with a lower credit score?
FHA loans generally offer more flexible credit guidelines than many conventional programs. However, FHA requirements and individual lender requirements still apply, and credit score is only one part of determining eligibility.
How quickly can my credit score improve?
There is no guaranteed timeframe. Credit scores can change as information on your credit reports changes, and the impact of any particular action depends on your individual credit profile.
Does my spouse's credit score affect our mortgage?
If both spouses apply for the mortgage, the lender will evaluate credit information according to the applicable loan program and underwriting guidelines. How multiple borrowers' credit scores are treated can vary by mortgage program.
Does my credit score affect more than my interest rate?
Yes. Depending on the mortgage program, credit can affect eligibility, pricing, mortgage insurance, down-payment requirements, and other financing terms.
