If you have been trying to secure a property investment loan in Melbourne since February 2026, you have likely noticed that something has shifted.
It’s frustrating to know that some lenders are saying no where they previously said yes, and that approvals are taking a little longer than they did this time last year.
One of the reasons for this is a decision by the Australian Prudential Regulation Authority (APRA) to introduce a debt-to-income cap, which came into effect in February. It is the most consequential structural change to Australian investment lending in years, and most commentary on it has either overstated the restriction or undersold its practical impact.
This article explains how the debt-to-income (DTI) cap actually works and what Melbourne investors can do right now to maximise their chances of a successful application.
Key takeaways
- The DTI cap is a lender quota restriction, not a borrowing ban. Banks are limited to writing no more than 20% of new mortgage lending at a debt-to-income ratio of six times gross income or higher. High-DTI loans are still available, but lenders are managing their allocation carefully.
- Investors with existing debt are most affected. If you hold two or more properties, your total debt load is likely already pushing against the six-times threshold, which changes how your application needs to be structured.
- Lender selection and application timing matter more than ever. Some lenders exhaust their high-DTI quota early in the quarter. Applying to the right lender at the right time is a genuine strategic consideration.
- Non-bank lenders may be an option. For investors who cannot get approval through a major bank under the new rules, non-bank lenders offer a legitimate and increasingly relevant pathway.
- Income structuring and debt sequencing can materially improve your DTI position. The right preparation before lodging an application can be the difference between approval and decline.
How the DTI Cap works
APRA’s debt to income cap does not prevent an individual borrower from obtaining a high-debt-to-income loan. Instead, it limits how many of those loans a bank can approve.
Under the rule, no more than 20% of a lender’s new mortgage lending can be written at a DTI ratio of six times gross income or higher, with investor and owner-occupier loans measured separately.
In real terms, lenders are now working within a quota. When that quota has barely been used, a high-DTI application may have a better chance of moving through. However, if a lender is getting close to its 20% limit, the same application may be declined, even if the borrower’s financial position is otherwise strong.
For Melbourne investors, a strong application still matters, but it is no longer the only factor. The lender’s own position at the time you apply can also affect the outcome.
APRA has framed the cap as a risk management tool, designed to reduce the banking system’s exposure to highly leveraged borrowers rather than block individual borrowers from accessing credit.
Will the DTI cap affect you?
Not every Melbourne investor will run into the DTI cap as a real hurdle. For borrowers with high income and lower existing debt, buying one investment property may still sit comfortably below the six-times income threshold. In those cases, the cap won’t impact your application.
It is more likely to affect investors who already have significant debt, usually those with two or more properties, where total borrowings across all loans are close to or above six times their gross income. For these borrowers, the cap can change which lenders are willing to look at the application, how the loan needs to be structured and whether the purchase can go ahead within the planned timeframe.
The Mortage and Finance Association of Australia (MFAA) has noted that the DTI cap is specifically aimed at reducing future risk in the system rather than restricting access for well-qualified borrowers, which is a useful distinction. The policy intent is not to stop experienced investors from building portfolios. It is to limit the concentration of very high leverage across the banking system.
How Melbourne investors can still get a property investment loan
Your first step is to work with an experienced broker who understands investment property lending and will help you to:
- Choose your lender strategically. Not all lenders are equally constrained by the DTI cap. A broker with current visibility across multiple lenders’ portfolios can identify where capacity exists and direct your application accordingly. This is one of the most underappreciated advantages of working with an active broker in the investment lending market right now.
- Review your income position before you apply. DTI is calculated against gross income, which means any legitimate income sources that are not currently documented, rental income, trust distributions, business income, or income from a spouse or partner may improve your DTI ratio if properly evidenced. A property investment loan assessment should start with a complete picture of your income, not just your PAYG summary.
- Sequence your debt carefully. If you are planning multiple acquisitions, the order in which you lodge applications can affect your DTI at each stage. Getting the sequencing right before you start avoids the situation where an early application consumes capacity that a later, more strategically important loan would have needed.
- Consider non-bank lenders as a genuine first option. Non-bank lenders are not subject to APRA’s DTI cap, which means they operate without the quota constraint reshaping bank lending. For investors whose DTI profile exceeds 6x, a non-bank lender may be the most direct path to approval, although you need to take their individual assessment methods into account.
For investors whose portfolios include or are considering an SMSF structure, it is worth noting SMSF loans are assessed differently and may offer an additional pathway, depending on your overall structure.
