If you’re an investor thinking about your next property purchase, refinancing an existing loan, or reshaping your portfolio, you may have noticed growing discussion around changes to the debt-to-income ratio in Australia taking effect from 1 February.
For many investors, regulatory updates like this can feel technical or unclear at first. It’s natural to question whether borrowing will become harder, whether investment plans need to change, or whether it’s better to act now or wait.
From a regulatory perspective, these changes aren’t about stopping people from investing, they’re about how lenders assess risk and manage higher levels of debt across the system.
In this blog, we explain what the debt-to-income ratio changes involve, why they’re being introduced, and what investors should be thinking about now, so they can navigate the evolving lending environment with clarity and confidence.
What Is the Debt-to-Income (DTI) Ratio in Australia?
First, let’s get clear on what is DTI. In simple terms, your DTI compares the total amount of debt you have to your overall income. Lenders, including banks and other financial institutions, use this ratio to gauge your ability to manage repayments and assess your eligibility for credit. The higher your DTI, the more “stretched” your finances may appear to a lender.
How DTI Is Calculated?
To calculate your DTI, you add up all your debts (such as home loans, personal loans, credit cards, and other borrowings) and divide that total by your gross annual income (your income before tax and other deductions).
For example:
Imagine you and your partner have:
- A home loan of $400,000
- A personal loan of $14,000
- A credit card balance of $4,000
That brings your total debt to $418,000. If your combined annual income is $160,000, your DTI would be: 418,000 / 160,000 = 2.61
This means your total debt is 2.61 times your annual income. Lenders use this ratio to assess how comfortably you could manage repayments, especially if interest rates were to rise or your financial situation changes.
What’s Changing from 1 February?
From 1 February, the Australian Prudential Regulation Authority (APRA) is introducing a new limit on high DTI lending.
Under the new framework:
- Banks can allocate no more than 20% of new loan approvals to borrowers with a debt-to-income ratio above six.
- The cap applies separately to investors and owner-occupiers
- Most owner-occupiers and first home buyers are unlikely to be affected, as they typically borrow at lower debt-to-income levels.
- Some loan types, such as certain construction and bridging loans, are excluded from the cap.
What Does This Mean for Investors?
For many investors, there may be no immediate impact. However, if your strategy relies on higher levels of leverage to grow your portfolio, it’s worth paying closer attention to how this change may affect you.
1. High-Leverage Borrowing Becomes More Competitive
Because lenders now have a limit on how many high-DTI loans they can approve, borrowers with higher DTIs may:
- Face stricter scrutiny
- Encounter reduced borrowing capacity
- Experience longer approval times or potentially miss out due to exhausted loan allocation by a lender for these requests
2. Lender Behaviour May Change Before February
In practice, some lenders may adjust their internal policies early to manage their exposure. This can result in:
- Tighter serviceability assessments
- Reduced appetite for certain investor profiles
- Greater emphasis on income quality and cash flow
3. Structure and Strategy Matter More Than Ever
Under the new DTI framework, lenders look at your full financial picture, not just your property loans. This means all existing debts are considered when assessing your borrowing position, including:
- Investment and owner-occupied home loans
- Personal and car loans
- Credit card limits
- Buy-now-pay-later facilities
Because of this, how your lending is structured and how your income is assessed, plays a much bigger role in borrowing outcomes.
What Investors Should Be Doing Now?

With these changes approaching, it’s a good moment to pause and take a clear look at where you’re currently positioned. This isn’t about rushing to make decisions or changing plans overnight. It’s about understanding how your existing debts, income, and future borrowing plans might be viewed under the new framework.
1. Understand Your Current Position
Know your approximate debt to income ratio across all lending. Many investors underestimate how close they are to key thresholds.
2. Review Upcoming Plans
If you’re planning to:
- Purchase an investment property
- Refinance
- Restructure debt
- Assist family members
It’s worth assessing how these plans interact with the new DTI environment.
3. Seek Expert Advice Early
This is where advice really adds value. An experienced finance advisor can help you:
- Model different scenarios
- Understand lender-specific interpretations
- Align borrowing decisions with long-term strategy, not just short-term approval
