APRA’s DTI Cap Is Here — And Property Investors Are Already Feeling It
From 1 February 2026, a new era of mortgage lending began in Australia. The Australian Prudential Regulation Authority (APRA) implemented a debt-to-income (DTI) lending cap that is reshaping how banks assess investor loan applications — and the impact is being felt well before many borrowers even knew the rule existed.
What Is the DTI Cap?
The new APRA rule prohibits authorised deposit-taking institutions (ADIs) — that includes all major banks and most lenders — from writing more than 20% of new loans to borrowers with debt exceeding 6 times their annual income. In plain terms: if your total debt is more than six times what you earn, most banks must now carefully limit how many customers like you they take on.
This is a significant structural shift in Australian lending policy. It moves beyond the traditional serviceability test — where lenders assess whether a borrower can afford monthly repayments — and introduces a blunt measure of total debt load relative to income.
Why Is This Happening Now?
The catalyst is hard to ignore. Investor home loans surged 17.6% in the September 2025 quarter, with investment lending accounting for 40% of all new home loans — a level that caught APRA’s attention. Meanwhile, mortgages with DTI ratios between 4 and 6 reached a six-year high of over $67 billion, representing nearly half of all new loans written. Regulators were watching, and they moved.
Who Is Being Affected?
Here’s what is catching many investors off guard: banks are not waiting to hit the 20% ceiling before tightening. Some lenders have already set their own internal DTI thresholds below APRA’s limit — rejecting borrowers who technically pass the serviceability assessment but whose aggregate debt exceeds 6–7 times their income.
The investors hit hardest include:
- Those with multiple investment properties, even where rental income fully covers repayments
- Borrowers with clean credit histories who have never missed a payment
- High-income earners whose total debt simply scaled with their portfolio
In short: you can be financially responsible, income-stable, and still be knocked back. The DTI ratio is becoming a filter that operates independently of your ability to service the loan.
“The Industry Is Moving Faster Than the Regulation”
This observation from within the industry captures the current dynamic precisely. While APRA’s rule only took effect in February 2026, the major banks began adjusting their credit policies months earlier in anticipation. Borrowers applying today may find themselves declined by banks that haven’t even reached their regulatory limit yet — simply because those banks are managing their exposure proactively.
This creates an uneven landscape where knowing which lenders still have capacity is as important as understanding your own financial position.
What About Non-Bank Lenders?
There is an important distinction in the regulation: APRA’s DTI cap applies only to ADIs (banks). Non-bank lenders — including many specialist mortgage funds and wholesale lenders — are not subject to the same cap. For investors who are declined by traditional banks, non-bank lenders may represent a viable alternative pathway.
However, it’s important to approach this with clear eyes. Non-bank products may carry different interest rates, fee structures, or loan conditions. The right decision depends on your complete financial picture — which is exactly why getting proper, personalised advice matters more now than it has in years.
What Should Investors Do Right Now?
- Know your DTI ratio — add up your total debt and divide by your gross annual income
- Don’t assume one bank’s decision represents all lenders — policies vary significantly
- Work with a broker who understands the new landscape — lender selection is now a strategic decision, not just a rate comparison
- Plan your portfolio sequentially — structuring purchases to manage DTI over time is now essential for serious investors
