The RBA meets next Tuesday and banks are split on the call. But APRA's 6x debt-to-income cap, in effect since February, is the bigger structural change reshaping borrowing power for high-earning medical professionals in 2026.
Key Takeaways
- The RBA decides Tuesday June 16. CBA expects a hold. NAB now thinks the next move is down.
- APRA's 6x DTI cap, in effect since February, is the bigger structural change for high earners.
- The cap applies to 20% of new lending each quarter, owner-occupier and investor portfolios tracked separately.
- Doctors retain access to 95% LVR with no LMI on owner-occupier purchases at several majors.
- Run your full household DTI calculation before applying. It's the number banks are now tracking.
The RBA meets next Tuesday. Major banks are split. CBA expects a hold. NAB thinks the next move is down. For doctors and other high-income earners, the decision matters less than the structural shift that happened in February. APRA's 6x debt-to-income cap is the thing actually reshaping borrowing power in 2026.
Why Tuesday matters less than you think
The cash rate sits at 4.35% after three hikes this year. The Reserve Bank board meets Tuesday June 16 at 2:30pm. CBA economists are calling a hold after May's increase. NAB's Chief Economist Sally Auld has shifted the bank's stance, saying she has greater conviction that the next move is down, with less conviction on the timing.
Either way the decision goes, the impact on your monthly repayments is modest. On a $1.2m loan, 25 basis points moves you by roughly $150 a month. Real money over a year, but not the thing reshaping borrowing capacity right now.
The bigger change happened on 1 February. Most borrowers haven't felt it yet because the cap only bites once you cross a specific threshold.
APRA's 6x DTI cap is the real story
Since February, banks have been capping home loans above six times household income at 20% of new lending each quarter. The cap applies separately to owner-occupier and investor portfolios. New builds, construction loans, and bridging finance are exempt.
For most owner-occupiers, the cap hasn't bitten. Average DTI on owner-occupier loans sits well below six. But for high earners running an investment property strategy, including a lot of doctors using equity to build a portfolio, the maths has changed.
Here's the practical effect. A specialist on $400k who owns a $1.5m PPR with $900k of debt is at 2.25x DTI before any investment property. Add a $1.2m investment loan and you're at 5.25x. Add a second at $1m and you've crossed 6x. Now you're competing for a slot in the 20% high-DTI bucket each bank has per quarter.
That bucket fills up. And not every applicant gets a seat.
What this means in practice
Three things have shifted in how brokers are structuring deals right now.
First, lenders are getting more selective about which high-DTI loans they approve. The 20% bucket isn't equal opportunity. Banks prioritise borrowers with strong serviceability buffers, clean repayment history, and stable income. That favours medical professionals, but doesn't guarantee anything.
Second, timing matters more. Quarterly measurement means lenders track their DTI ratio across each three-month window. Applying late in a quarter when a bank is near its cap is harder than applying early. We've seen approvals slow at certain majors in the last week of a quarter and pick back up at the start of the next one.
Third, lender choice matters more than it used to. Some Tier 2 lenders and non-banks aren't bound by APRA's limits in the same way. For investors pushing past 6x, the path often runs through a non-major rather than fighting for a slot at one of the Big Four.
This is the kind of structural detail that doesn't make the property pages but is what's actually determining who gets approved this quarter.
What to do before Tuesday's decision
If you're a medical professional planning a purchase or refinance in the next six months, three moves are worth making now regardless of what the RBA does Tuesday.
Run the DTI calculation across your whole position. Most people only know their loan-to-value ratio. Total household debt divided by gross household income is the number lenders are now tracking. If you're approaching 6x, structure becomes the conversation.
Use the LMI waiver properly. Doctors still get up to 95% LVR with no LMI on owner-occupier purchases at several majors. Loan sizes typically cap around $5m per security. The waiver is worth roughly $40,000 to $60,000 on a $1.5m purchase. That hasn't changed in 2026.
Stress-test your own numbers at 3% above your offered rate. APRA dropped its mandatory 7% serviceability floor earlier this year and let lenders set their own minimum with a 2.5% buffer. That buffer is the bank's test, not yours. If you can't service the loan at 3% over your rate, the buffer is doing you a favour by saying no.
One more. If you're sitting on equity in your PPR thinking about a second investment property this year, get the numbers checked before you go to market. Knowing where you sit on the DTI scale changes which lenders to approach and how to sequence applications. We've seen clients lose deals because they applied to the wrong bank at the wrong point in a quarter.
The RBA matters. It just isn't the only thing that matters anymore.
