Westpac Rate Increases on Residential Investment Property Loans

September 08, 2025

How Do These Changes Impact Property Investors?

Increased Borrowing Costs

Higher interest rates mean more expensive loans. If you had an investment property financed with a variable-rate loan, your monthly repayments might increase. For example:

  • A $500,000 loan at 4% interest costs roughly $2,387/month.
  • Increasing to 4.75% raises that to about $2,607/month.

That's an extra $220 every month, or $2,640 annually. Over time, this affects your cash flow and investment returns.

Effect on Investment Viability

Investors planning their next purchase should re-calculate their figures. Higher rates may reduce the rental yield or return on investment. If your forecasted gross rental income stays the same but your expenses increase, your net yield drops.

Impact on Refinancing and Debt Serviceability

If you're considering refinancing or renewing an existing loan, these rate hikes could limit your borrowing capacity. Banks assess how much you can borrow based on your income and expenses, including new, higher interest payments.

Broader Market Implications

Some analysts expect continued rate increases into 2026. This could slow property price growth or even cause minor declines. Investors need to revisit their strategy, especially if they rely heavily on borrowed money.


What Should Investors Do Now?

Navigating these changes requires strategic planning. Here are practical steps.

1. Review Your Loan Agreements

  • Check your current interest rate and loan type. Fixed rates are unaffected by recent hikes until they expire.
  • Understand your repayment schedule. Be prepared for increased payments once fixed terms end.
  • Explore refinancing options. Locking in fixed rates before further hikes could protect you from rising costs.

2. Reassess Your Investment Portfolio

  • Update your cash flow projections with the new interest rates.
  • Calculate your net rental yield. Ensure it remains positive after increased expenses.
  • Evaluate whether to buy or hold. Higher borrowing costs might mean delaying new acquisitions or seeking properties with higher rental returns.

3. Strengthen Your Financial Position

  • Document your income and savings. Lenders prefer a stable financial profile.
  • Consider down payment sources. Using savings, or family support can reduce loan sizes and interest costs.
  • Maintain a good credit score. It can help you access better refinancing options.

4. Understand Policy and Regulatory Changes

  • The Foreign Investment Review Board (FIRB) rules remain strict for foreign investors. Ensure mortgage applications comply, especially regarding ownership rights and permits.
  • Be aware of Lenders Mortgage Insurance (LMI) costs if you're borrowing more than 80% of property value.

Practical Tips for International Buyers and New Investors

Many of our clients are first-time buyers or international investors unfamiliar with Australian systems. Here are insights to guide you:

  • Converting overseas savings: You can transfer funds into AUD via foreign exchange platforms, but watch for exchange rate fluctuations.
  • Understanding LMI: This is insurance protecting lenders if you default. It often applies if your deposit is less than 20%.
  • Navigating visa requirements: Most lenders require holding specific visas, such as a temporary or permanent residency visa, to qualify for loans.
  • Using overseas income: Some lenders accept foreign income, but documentation like overseas tax returns and foreign bank statements are necessary.

In my 20+ years helping migrants secure mortgages, I've seen how these factors influence approval enough times. Preparation and understanding go a long way.

  • Westpac's rate hikes are part of a broader trend affecting the Australian mortgage market.
  • Increased interest rates mean higher expenses and potential adjustments to your investment strategy.
  • Review your loans, reassess your financial position, and consider locking in fixed rates if advantageous.
