Refinancing a home loan is a strategic financial decision Australians make for various reasons, such as securing a lower interest rate, consolidating debt, or accessing home equity. But while the benefits can be substantial, one often overlooked aspect is how refinancing can influence your credit score.

In this guide, we explore how different types of refinancing, including cash out refinance and home mortgage refinance, can impact your financial standing, especially your credit profile.

Understanding cash out refinance

A cash-out refinance is a refinancing option where you take out a new mortgage for more than you owe on your existing home loan and pocket the difference. Essentially, you access a portion of your home's equity in cash.

How it differs from other refinancing options

While standard refinancing typically focuses on securing a lower interest rate or better loan terms, a cash-out refinance allows you to leverage your equity. This option may come with a slightly higher interest rate and could extend your loan term, but it also provides liquidity for expenses like renovations or debt consolidation.

Benefits of cash out refinance

Accessing home equity

Cash-out refinancing is a popular way to access funds tied up in your property's value. For a deeper understanding of home equity and how to leverage it, see our guide on Home Equity. This can be particularly useful for major expenses or investments.

Potential for lower interest rates

If your credit score has improved since your original loan, you might qualify for a lower rate on your new loan, potentially reducing long-term interest costs.

Debt consolidation opportunities

Using the proceeds to pay off high-interest debts, such as credit cards or personal loans, can streamline repayments and potentially improve your overall financial health.

How refinancing affects your credit score

Your credit score is a critical factor lenders assess when approving any mortgage or refinance application. Here's how refinancing may affect it:

  • Hard Credit Enquiry: When you apply to refinance, lenders conduct a hard enquiry, which may lower your credit score temporarily.
  • New Account Opening: A new loan means a new credit account, which affects your credit age (an important scoring factor).
  • Loan Closure: Your original mortgage will be closed, which could impact your credit mix and average account age.
  • Debt-to-Income Ratio: Cash-out refinancing increases your loan amount, which could raise your perceived credit risk.

However, these effects are usually short-term, and responsible refinancing can improve your score over time by reducing your overall debt and maintaining a strong repayment record.

Weighing the pros and cons

Benefits

  • Improved loan terms and reduced interest costs
  • Simplified repayments with consolidated debt
  • Improved cash flow from better loan structure

Drawbacks

  • Potential short-term dip in credit score, particularly if multiple credit enquiries are made within a short period. However, credit scores are influenced by a variety of factors including repayment history, credit utilisation, and length of credit history.
  • Higher total interest if the loan term is extended
  • Possible fees and costs associated with refinancing

It's crucial to weigh the short-term impacts on your credit score, along with other considerations such as refinancing costs, changes to loan terms, and total interest payable, against the potential long-term financial benefits.

Home mortgage refinance basics

Refinancing your mortgage involves replacing your current home loan with a new one, typically to secure better terms. Common reasons for refinancing include:

  • Lowering interest rates
  • Changing loan types (e.g., variable to fixed)
  • Reducing monthly repayments
  • Accessing equity for other purposes
  • Consolidating existing debts into a single loan
  • Unlocking new loan features such as offset accounts or redraw facilities

Understanding your current financial goals is key to determining whether refinancing is the right strategy. For a broader overview, browse our Refinancing Hub.

Potential risks and considerations

Upfront costs

Refinancing often incurs costs such as discharge fees from your current lender, application fees, valuation charges, and legal expenses. It's important to calculate whether the savings outweigh the costs.

Impact on loan terms

Extending the life of your loan could mean you pay more interest in the long run, even if your monthly repayments are lower.

Market conditions

Changing interest rates and property market fluctuations can affect the value and viability of refinancing.

Conclusion

Refinancing a home loan, whether through a traditional or cash-out method, could influence your financial trajectory and your credit score, depending on your individual circumstances and how the refinancing process is managed. By understanding the implications and managing the process carefully, you can harness the benefits of refinancing while safeguarding your credit health.
