The Role of Credit Score When Buying a Home

Posted on May 26, 2025 in For Buyers

When it comes to purchasing a home, your credit score plays a crucial role in determining your eligibility for a mortgage, the interest rate you'll receive, and the overall affordability of homeownership. Understanding how credit scores impact the home-buying process can help you prepare financially and potentially save thousands of dollars over the life of your loan.

What Is a Credit Score?

A credit score is a three-digit number that represents your creditworthiness. Lenders use it to assess the risk of lending you money. Credit scores typically range from 300 to 850, with higher scores indicating better credit health. The most commonly used scoring model is the FICO Score, which is calculated based on factors such as:
  • Payment history (35%) – Whether you've made past payments on time.
  • Credit utilization (30%) – How much of your available credit you're using.
  • Length of credit history (15%) – How long your credit accounts have been open.
  • New credit (10%) – How frequently you've applied for new credit.
  • Credit mix (10%) – The variety of credit accounts you have, such as credit cards, auto loans, and mortgages.

Why Your Credit Score Matters When Buying a Home

1. Mortgage Approval

Lenders use your credit score to determine whether you qualify for a mortgage.  When your downpayment is less than 20 percent, mortgage insurance will be required.  At least one borrower (or guarantor) must have a credit score that is greater than or equal to 600 at the time of the request for insurance.  Mortgages where the downpayment is greater than 20 percent may allow lower scores. However, a higher score increases your chances of approval and provides access to better mortgage terms.

2. Interest Rates

Your credit score directly impacts the interest rate you receive. A higher score typically results in lower interest rates, which means lower monthly payments and less money paid in interest over the life of the loan. Even a small difference in interest rates can translate into significant savings.

3. Down Payment Requirements

A strong credit score can sometimes lead to lower down payment requirements. For example, insured mortgages require as little as 5% down for borrowers with excellent credit, while those with lower scores might need to put down a larger percentage.

4. Mortgage Amount and Terms

Lenders may impose stricter borrowing limits or less favorable terms for buyers with lower credit scores. A higher credit score can help you qualify for a larger mortgage amount, making it easier to purchase your desired home.

How to Improve Your Credit Score Before Buying a Home

If your credit score isn't where you'd like it to be, there are steps you can take to improve it before applying for a mortgage:
  • Pay bills on time – Late payments can have a significant negative impact on your score.
  • Reduce credit card balances – Keeping your credit utilization below 30% can help boost your score.
  • Avoid opening new credit accounts – Too many new inquiries can lower your score.
  • Check your credit report – Review your report for errors and dispute any inaccuracies.
  • Build a long credit history – Keeping older accounts open can positively impact your score.

Final Thoughts

Your credit score is one of the most important factors in the home-buying process. A higher score can lead to better mortgage terms, lower interest rates, and increased affordability. If you're planning to buy a home, taking proactive steps to improve and maintain a strong credit score can make a significant difference in your homeownership journey.By understanding how credit scores influence your mortgage options, you can make informed decisions that set you up for financial success in your new home.
