When it comes to purchasing a home, most buyers rely on a mortgage to finance the purchase. Securing a mortgage, however, is not as simple as submitting a loan application. Lenders take several factors into consideration before approving a mortgage, and one of the most important factors is creditworthiness. In this article, we will explore the role of credit in mortgage approval and discuss how you can improve your chances of qualifying for a home loan.

Understanding Credit Scores

Before delving into how credit affects mortgage approval, it is essential to understand credit scores. Credit scores are numerical representations of an individual’s creditworthiness and are based on several factors such as payment history, credit utilization, length of credit history, and types of credit used. The most commonly used credit scoring model is the FICO score, which ranges from 300 to 850.

Minimum Credit Score Requirements

Different lenders have varying minimum credit score requirements for mortgage approval. However, a credit score of 620 or higher is generally considered the minimum threshold for conventional mortgages. To qualify for more competitive interest rates and terms, a credit score of 700 or higher is preferable. It is important to note that these minimum requirements can vary based on other factors such as the loan amount, down payment, and the specific type of mortgage being sought.

Impact of Credit on Interest Rates

Credit scores play a significant role in determining the interest rate a borrower receives on their mortgage. In general, borrowers with higher credit scores are considered less risky by lenders and are rewarded with lower interest rates. This is because a high credit score indicates a history of responsible financial behavior and a lower likelihood of defaulting on the loan. Conversely, borrowers with lower credit scores may be seen as higher risk and may be charged higher interest rates to compensate for that risk.

Credit and Loan-to-Value Ratio

Aside from interest rates, credit also affects the loan-to-value (LTV) ratio a lender is willing to accept. The LTV ratio compares the loan amount to the appraised value of the property. A higher credit score often translates to a lower LTV ratio, which means borrowers may be able to borrow a larger percentage of the property’s value. Conversely, borrowers with lower credit scores may be limited to a lower LTV ratio, requiring a larger down payment.

Steps to Improve Credit for Mortgage Approval

If your credit score is less than ideal, there are steps you can take to improve it before applying for a mortgage:

1. Review Your Credit Report

Obtain a free copy of your credit report from each of the three major credit bureaus – Equifax, Experian, and TransUnion. Review the reports for any errors or discrepancies that may be negatively impacting your credit score.

2. Pay Bills on Time

Payment history is a significant factor in credit score calculation. Make sure to pay all your bills, including credit card bills, on time. Set up automatic payments or use reminders to help you stay organized.

3. Reduce Debt

High credit card balances can negatively impact your credit score. Aim to reduce your overall debt and keep your credit utilization ratio below 30%. Paying off smaller debts first can also help improve your credit score.

4. Avoid Opening New Credit Accounts

Opening new credit accounts can lower the average age of your credit history and may temporarily reduce your credit score. It is advisable to refrain from opening new credit accounts in the months leading up to your mortgage application.

5. Work with a Credit Counselor

If you’re struggling to improve your credit score, consider working with a credit counselor. These professionals can provide guidance and assistance in developing a plan to improve your creditworthiness.

The Importance of Pre-Approval

Before starting your home search, obtaining mortgage pre-approval is crucial. Pre-approval involves a lender evaluating your financial information and creditworthiness to determine the loan amount you qualify for. It provides you with a clear understanding of your budget and strengthens your negotiating power when making an offer on a home.


The role of credit in mortgage approval cannot be overstated. A good credit score not only increases your chances of qualifying for a mortgage but also affects the interest rates and terms you are offered. By understanding your credit and taking proactive steps to improve it,  you can position yourself for success in obtaining a home loan.

Remember to review your credit report regularly, pay bills on time, reduce debt, avoid opening new credit accounts, and consider seeking guidance from a credit counselor if needed. With a solid credit foundation, you can navigate the mortgage approval process with confidence.
