Does Buying a House Increase Your Credit Score?

Buying a house is a significant financial milestone. While homeownership itself doesn’t directly increase a credit score, the process of securing and managing a mortgage can significantly influence it, leading to both positive and negative changes. Understanding these nuances is important, as the journey involves several steps that impact one’s financial profile.

How Mortgage Applications Affect Credit Scores

Applying for a mortgage triggers actions that temporarily impact your credit score. Lenders perform a “hard inquiry” on your credit report to assess creditworthiness. This inquiry occurs when a financial institution checks your credit in response to an application, typically causing a small, temporary dip in your credit score, often by fewer than five points. While the inquiry remains on your credit report for up to 24 months, its impact on your score usually lasts for about 12 months.

When shopping for a mortgage, multiple inquiries from different lenders within a short period are often treated as a single inquiry by credit scoring models like FICO. This allows individuals to compare loan offers without their score being penalized for each separate application. For FICO scores, this grouping window can be up to 45 days. Opening a new, substantial credit account, such as a mortgage loan, can also slightly reduce the average age of all your credit accounts, contributing to a temporary dip.

The Impact of Mortgage Payments on Credit Scores

The management of a mortgage loan significantly influences credit scores, largely through consistent payment behavior. Making timely and consistent mortgage payments demonstrates responsible financial behavior, which can substantially boost a credit score over the long term. Conversely, late or missed mortgage payments can severely damage a credit score and remain on a credit report for up to seven years. Even a single missed payment can lead to a significant score drop, with potential reductions of around 50 points.

A mortgage also contributes to the “credit mix” component of a credit score. As an installment loan, a mortgage diversifies a credit profile, showing an individual can manage different types of credit responsibly. Initially, a new mortgage represents a large amount owed. However, as the principal balance decreases with consistent monthly payments, this reduction in the “amounts owed” can positively affect the credit score.

Components of a Credit Score

Credit scores, such as FICO or VantageScore, are numerical representations of an individual’s creditworthiness, typically ranging from 300 to 850. These scores are calculated using information from credit reports and are composed of five key factors:

Payment history: This is the most significant factor, accounting for about 35% of a FICO score. It assesses whether past credit accounts have been paid on time and consistently, including details on delinquencies, public records, and the number of accounts paid as agreed.
Amounts owed (credit utilization): This substantial component makes up about 30% of the score. It considers the total amount of debt an individual carries and the proportion of available credit being used, particularly on revolving accounts like credit cards.
Length of credit history: Contributing approximately 15% to the score, this evaluates how long credit accounts have been open and the average age of all accounts. Longer credit histories generally indicate more experience managing debt.
New credit: This accounts for about 10% of a credit score and reflects recent applications for credit, including the number of new accounts and recent credit inquiries. Opening several new accounts in a short period can signal higher risk.
Credit mix: Also contributing around 10% to the score, this assesses the variety of credit types an individual manages, such as a combination of installment loans (like mortgages or auto loans) and revolving credit (like credit cards). A diverse mix can indicate financial management capability.

Understanding Your Credit Report Before Home Buying

Before embarking on the home-buying process, it is important to understand the information contained within your credit report. A credit report serves as a detailed record of your credit history, compiled by credit reporting agencies such as Equifax, Experian, and TransUnion. These reports contain personal information, account histories, public records like bankruptcies, and a log of credit inquiries. Lenders use these reports to gauge your financial reliability and determine loan eligibility and interest rates.

It is highly recommended to review your credit reports for accuracy well in advance of applying for a mortgage. Errors or discrepancies, such as accounts you do not recognize, incorrect balances, or outdated negative information, could negatively impact your credit score and affect loan terms. You are entitled to a free copy of your credit report weekly from each of the three nationwide credit reporting agencies through AnnualCreditReport.com. Regularly checking these reports allows for early identification and dispute of inaccuracies, helping to ensure your credit profile accurately reflects your financial standing.
