What Is the APRA DTI Cap and How Does It Work?
Australia’s banking regulator, APRA (Australian Prudential Regulation Authority), introduced a new Debt-to-Income (DTI) lending cap from 1 February 2026. Under this rule, authorised deposit-taking institutions — your major banks and credit unions — can only write up to 20% of new mortgages to borrowers whose total debt is six times or more their annual gross income.
This cap applies separately to owner-occupier and investor lending portfolios. It’s important to note that this is not a blanket ban — it’s a quota system. But as more borrowers bump against the threshold, lenders are becoming increasingly selective about who receives approval.
Who Is Most Affected?
Property investors are bearing the brunt of this change. Current data shows that approximately 10% of investor loans already exceed the 6x DTI threshold — more than double the 4% rate for owner-occupiers. This means the investor segment is far more exposed as banks approach their quarterly lending limits.
Those most likely to be affected include:
- Investors with two or more properties where aggregate debt has grown over time
- Borrowers in high-cost property markets where purchase prices are significantly higher relative to income
- Upsizing first-home buyers who already own one property
- High-income earners who have used leverage to build a diversified portfolio
Mortgage broker Alex Veljancevski from Eventus Financial noted that some banks are already moving ahead of APRA’s ceiling: “We’re seeing investors who pass the bank’s own serviceability assessment — they can clearly afford the repayments — but the application still can’t proceed because their total debt is above six or seven times their income.”
Banks Are Tightening Even Before the Cap Kicks In
One of the most important things to understand is that many banks are not waiting until they reach the 20% APRA ceiling before acting. Industry insiders report that several major lenders have already quietly lowered their own internal DTI limits — meaning borrowers may be declined at a threshold even lower than the regulatory one.
This creates a confusing landscape where the same borrower could receive different outcomes at different lenders. Having expert guidance to navigate which lenders still have flexibility is now more important than ever.
Non-Bank Lenders: A Viable Alternative Path
There is a silver lining. APRA’s DTI cap does not apply to non-bank lenders — specialist financiers who operate outside the traditional banking system. For well-qualified borrowers who are being turned away by their bank, non-bank lenders can offer genuine, competitive choices.
That said, non-bank products can come with different rate structures and conditions. Getting personalised assistance from a qualified mortgage broker ensures you understand all options and make an informed decision suited to your specific circumstances.
If you’ve been told “no” by your bank, or you’re concerned that new DTI rules might affect your upcoming purchase or refinance, the right home loan for your needs may still be within reach — it just might require a different approach.
