Which Credit Score is Used for Mortgages: Know Before You Apply

When you’re preparing to buy a home, understanding which credit score is used for mortgages is essential. Your credit score significantly impacts your ability to secure a mortgage and influences the terms and interest rates you may receive. 

So, which credit score is used for your mortgage? Mortgage lenders typically rely on your FICO scores from the three major credit bureaus: Experian, TransUnion, and Equifax. They usually obtain a tri-merge report that combines information from all three bureaus and use the median score to evaluate your mortgage application. This process helps lenders get a comprehensive view of your creditworthiness, ensuring they make informed lending decisions.

Understanding Credit Scores

Definition of Credit Scores

A credit score is a numerical representation of your creditworthiness, based on your credit history. It helps lenders assess the risk of lending you money. Scores typically range from 300 to 850, with higher scores indicating better credit health. This number is calculated using various factors, including payment history, amounts owed, length of credit history, credit mix, and new credit.

Different Types of Credit Scores: FICO vs. VantageScore

While there are several types of credit scores, FICO and VantageScore are the most commonly used. 

FICO Score:

– Developed by the Fair Isaac Corporation, FICO scores are widely used by lenders.

– There are different versions of FICO scores, with the most commonly used in mortgage lending being FICO Score 2, 4, and 5.

– FICO scores range from 300 to 850 and are calculated based on five main factors: payment history, amounts owed, length of credit history, credit mix, and new credit.


– Created by the three major credit bureaus (Experian, TransUnion, and Equifax) as a competitor to FICO.

– VantageScore uses a similar range of 300 to 850 and considers many of the same factors as FICO, but with slight differences in weighting.

– Newer models of VantageScore, such as VantageScore 4.0, incorporate additional data like trends in credit behavior and rental payment history.

Importance of Credit Scores in Financial Health

Credit scores are crucial in various aspects of financial health. They influence your ability to secure loans, credit cards, and mortgages. A high credit score can qualify you for lower interest rates and better loan terms, saving you money over time. Conversely, a low credit score can limit your borrowing options and result in higher interest rates.

Maintaining a good credit score can also affect other areas of your life, such as rental applications, insurance premiums, and even job applications in certain industries. It reflects your financial responsibility and ability to manage debt effectively, which is why it’s essential to monitor and improve your credit score regularly.

Understanding and managing your credit scores can open doors to better financial opportunities and stability, making it a fundamental aspect of personal finance.

Credit Score Models Used by Mortgage Lenders

Explanation of the FICO Scoring Models Used

When it comes to mortgage lending, FICO scores are the most trusted indicators of a borrower’s creditworthiness. Mortgage lenders often use specific versions of FICO scores tailored for each major credit bureau. These versions are:

FICO Score 2 (Experian/Fair Isaac Risk Model v2)

FICO Score 2, also known as the Experian/Fair Isaac Risk Model v2, is used by mortgage lenders to assess the risk of lending based on Experian’s data. This version considers a variety of factors, including payment history, credit utilization, length of credit history, new credit, and credit mix.

FICO Score 5 (Equifax Beacon 5)

FICO Score 5, or Equifax Beacon 5, is another older model utilized by mortgage lenders. It draws on data from Equifax, evaluating similar factors to provide a comprehensive view of a borrower’s creditworthiness. This score helps lenders understand the risk associated with offering a mortgage loan.

FICO Score 4 (TransUnion FICO Risk Score 04)

FICO Score 4, known as the TransUnion FICO Risk Score 04, is used by lenders to assess credit risk based on TransUnion’s credit data. Like the other FICO models, it takes into account payment history, amounts owed, length of credit history, new credit, and credit mix.

Why These Older Versions Are Still Used by Lenders

Despite advancements in credit scoring models, mortgage lenders continue to rely on these older FICO versions for several reasons:

1. Standardization: These models have been widely adopted and standardized across the mortgage industry. This consistency helps ensure that credit risk assessments are comparable and reliable across different lenders.

2. Regulatory Requirements: Government-sponsored enterprises (GSEs) like Fannie Mae and Freddie Mac have historically required these specific FICO scores for mortgage underwriting. This regulatory requirement has entrenched their use in the industry.

3. Predictive Power: Even though they are older, these FICO models have a proven track record of effectively predicting mortgage default risk. Lenders trust these models because they have been refined over many years and are well understood.

4. Comprehensive Reporting: The older FICO scores are integrated into tri-merge credit reports, which combine data from all three major credit bureaus. This comprehensive view of a borrower’s credit history ensures that lenders have the most complete information available when making lending decisions.

Understanding these specific FICO scoring models and their continued use helps borrowers know what to expect when applying for a mortgage, and it underscores the importance of maintaining a strong credit profile.

How Lenders Use Credit Scores

The Tri-Merge Report: Combining Reports from Equifax, Experian, and TransUnion

When you apply for a mortgage, lenders pull a tri-merge credit report. This report combines your credit information from the three major credit bureaus: Equifax, Experian, and TransUnion. The tri-merge report provides a comprehensive view of your credit history by integrating data from all three sources. This ensures that lenders have the most complete and accurate picture of your creditworthiness.

How Lenders Select the Median Score from the Tri-Merge Report

From the tri-merge report, lenders obtain three separate FICO scores, one from each credit bureau. Instead of using the highest or lowest score, lenders typically use the median score to assess your creditworthiness. The median score is the middle value when the three scores are arranged in ascending order. This approach provides a balanced assessment, mitigating the potential impact of any outlier scores.

Example of How the Median Score is Determined

To illustrate how the median score is determined, consider the following example:

– Experian FICO Score 2: 720

– TransUnion FICO Score 4: 735

– Equifax FICO Score 5: 750

In this scenario, the scores are 720, 735, and 750. When these scores are arranged in ascending order, 735 is the middle value. Therefore, the lender would use 735 as the median score for the mortgage application. If two of the scores were identical, that score would be used regardless of whether it is the higher or lower number.

Using the median score helps ensure a fair assessment of your credit risk by avoiding potential bias from an unusually high or low score. This method allows lenders to make more informed lending decisions, ultimately impacting the terms and conditions of your mortgage.

Factors Influencing Your Credit Score

Payment History: Impact on Credit Score and Its Importance (35%)

Payment history is the most significant factor affecting your credit score, accounting for 35% of the total. This component reflects whether you have paid past credit accounts on time. Late payments, delinquencies, and collections can severely impact your score. Consistently making on-time payments demonstrates reliability to lenders, thereby boosting your credit score.

Amounts Owed: Credit Utilization and Its Effect (30%)

The amounts owed, or credit utilization, make up 30% of your credit score. This factor considers the total amount of debt you owe compared to your available credit limits. High credit utilization, meaning you’re using a large portion of your available credit, can negatively affect your score. Keeping your credit card balances low relative to your credit limits is essential for maintaining a healthy credit score.

Length of Credit History: Why Longer History Benefits Scores (15%)

Length of credit history contributes 15% to your credit score. A longer credit history provides more data on your borrowing and repayment behavior, making it easier for lenders to assess your creditworthiness. This factor includes the age of your oldest credit account, the age of your newest credit account, and the average age of all your accounts. Generally, a longer credit history will improve your credit score.

Credit Mix: Diversity in Credit Types and Its Minor Role (10%)

Credit mix, which accounts for 10% of your score, refers to the variety of credit accounts you have, such as credit cards, retail accounts, installment loans, finance company accounts, and mortgage loans. Having different types of credit can benefit your score because it shows you can manage various types of credit responsibly. However, this factor is less significant compared to payment history and amounts owed.

New Credit: Recent Inquiries and New Accounts (10%)

New credit accounts for the final 10% of your credit score. This factor includes the number of recently opened accounts and the number of recent inquiries by creditors into your credit report. Opening several new accounts in a short period can be seen as risky behavior, which can lower your score. It’s advisable to limit new credit applications when preparing to apply for a mortgage.

Understanding these factors and how they influence your credit score can help you make informed decisions to improve your credit health, ultimately leading to better mortgage terms and interest rates.

How to Improve Your Credit Score Before Applying for a Mortgage

Checking Your Credit Report: Importance of Reviewing and Correcting Errors

The first step in improving your credit score is to review your credit report from all three major credit bureaus: Experian, Equifax, and TransUnion. You’re entitled to a free annual credit report from each bureau, which you can request at [AnnualCreditReport.com](https://www.annualcreditreport.com). Carefully check your report for any errors, such as incorrect account information, inaccurate payment statuses, or fraudulent accounts. If you find any discrepancies, dispute them with the appropriate bureau to have them corrected. Accurate information on your credit report is crucial for maintaining a high credit score.

Paying Down Debt: Strategies for Reducing Credit Utilization

One effective strategy for improving your credit score is to pay down existing debt, particularly revolving credit like credit cards. Aim to keep your credit utilization ratio below 30%, meaning the amount of credit you’re using compared to your total available credit. For instance, if your credit limit is $10,000, try to keep your balances below $3,000. Reducing your debt not only improves your credit score but also signals to lenders that you manage your finances responsibly.

Avoiding New Credit: Why You Should Limit New Accounts Before Applying

In the months leading up to your mortgage application, it’s wise to avoid opening new credit accounts. Each new account results in a hard inquiry on your credit report, which can temporarily lower your score. Additionally, new accounts reduce the average age of your credit history, another factor that can negatively impact your score. By limiting new credit inquiries and focusing on maintaining your existing accounts, you can help preserve and potentially boost your credit score.

Establishing a Solid Payment History: Consistency in Paying Bills on Time

Payment history is the most significant factor in your credit score, making up 35% of the total calculation. To establish a solid payment history, ensure that all your bills, including credit card payments, loan installments, and utility bills, are paid on time. Setting up automatic payments or reminders can help you avoid missed or late payments. Consistent, on-time payments demonstrate to lenders that you’re a reliable borrower, which is essential for improving your credit score.

By focusing on these strategies, you can improve your credit score and enhance your chances of securing favorable mortgage terms. Regularly monitoring your credit, reducing debt, avoiding new credit inquiries, and maintaining a solid payment history are all crucial steps in achieving a better credit profile.

Common Myths About Mortgage Credit Scores

Myth: All Lenders Use the Same Credit Score

One common misconception is that all mortgage lenders use the same credit score to evaluate applications. In reality, while most lenders rely on FICO scores, they often use different versions and may weigh the scores differently depending on their specific criteria and the type of loan. For example, some lenders might use the FICO Score 2, 4, or 5, each tailored to different credit bureaus. Additionally, some lenders might consider newer scoring models like FICO 10 T or VantageScore 4.0 in certain situations.

Myth: Closing Old Accounts Always Improves Your Score

Many believe that closing old, unused credit accounts will automatically boost their credit score. However, this isn’t always the case. Closing an old account can reduce the average age of your credit history, which can negatively impact your score. Additionally, closing an account reduces your overall available credit, potentially increasing your credit utilization ratio if you have balances on other accounts. It’s generally better to keep old accounts open and unused, especially if they don’t have an annual fee.

Myth: Checking Your Own Credit Score Will Hurt Your Score

Another widespread myth is that checking your own credit score will lower it. This confusion arises from the difference between “hard” and “soft” inquiries. A hard inquiry occurs when a lender checks your credit report as part of a loan or credit application, which can slightly lower your score. In contrast, a soft inquiry, such as when you check your own credit score or a potential employer does a background check, does not affect your credit score. Regularly checking your own credit report is a good practice to ensure accuracy and monitor your credit health.

By debunking these common myths, you can make more informed decisions about managing your credit score and better prepare for the mortgage application process. Understanding the nuances of how credit scores work helps you maintain a healthy credit profile and secure the best possible terms for your mortgage.

FAQs on Mortgage Credit Scores

Do All Mortgage Lenders Use the Same Credit Score?

No, not all mortgage lenders use the same credit score. While most rely on FICO scores, they often use different versions tailored for each credit bureau: FICO Score 2 (Experian), FICO Score 5 (Equifax), and FICO Score 4 (TransUnion). Some lenders might also consider newer models like FICO 10 T or VantageScore 4.0 depending on the loan type and their specific criteria.

What is Considered a “Good” Credit Score for a Mortgage?

A “good” credit score for a mortgage typically starts at 620 for conventional loans. However, to secure the best rates and terms, a score of 740 or higher is often preferred by lenders. Different loan types have varying minimum credit score requirements:

– Conventional Loans: Minimum 620

– FHA Loans: Minimum 500 (with 10% down), 580 (with 3.5% down)

– VA Loans: No official minimum, but 620 is commonly required

– USDA Loans: No official minimum, but 640 is preferred.

Can You Get a Mortgage with a Low Credit Score?

Yes, it is possible to get a mortgage with a low credit score, though your options may be more limited and the terms less favorable. FHA loans are often accessible to borrowers with lower scores; you may qualify with a score as low as 500 if you can make a 10% down payment, or 580 with a 3.5% down payment. VA loans and USDA loans also offer more flexibility but generally prefer scores of 620 or higher.

How Do Joint Applications Affect Credit Score Considerations?

In joint applications, lenders will consider both applicants’ credit scores but typically use the lower median score of the two. For example, if one applicant has median scores of 720, 730, and 740, and the other has 680, 690, and 700, the lender will use the lower score, which is 700, for the application. This approach ensures that the lender assesses the risk based on the less favorable credit profile, which can impact the terms and conditions of the mortgage.

By understanding these common questions and answers about mortgage credit scores, you can better navigate the mortgage application process and work towards improving your credit health for better loan opportunities.
