Investor lending fell $4.2 billion in the June quarter, the sharpest drop since 2015

The number#

Australian investors wrote $37.1 billion of new home loans in the June quarter 2026, on the ABS Lending Indicators release. That is $4.2 billion below the March quarter, a 10.2% fall by value and 8.6% by number. In dollar terms, it is the biggest quarterly retreat in investor lending since 2015 (Canstar). In loan-count terms, the drop of 4,966 loans from March to June is the biggest quarterly fall since the September quarter 2022 (ABS media release).

Total new dwelling commitments across all borrower types fell 5.4% in the quarter, so investors were the accelerant on the way down, not the caboose. Owner-occupier lending was softer, but the composition tilt is what makes this print stand out: investor share of new home lending fell from a record 41% in the March quarter to 35.4% in the June quarter, on the latest APRA Quarterly ADI Property Exposures data.

That is a 5.6 percentage point retreat in the share of new flow inside a single quarter. Six months ago, on our own March quarter analysis, the story was that investor share was still climbing and APRA's 6x DTI cap had not yet started biting. The June number is the first quarter where the cap, the rate cycle and the tax rules have all landed together.

Why the pullback happened#

Three headwinds hit inside the June quarter, one on top of the next.

One, the cash rate rose to 4.35%. The RBA hiked 25 basis points on 5 May, the third increase of 2026 after February and March. Banks passed the rise through to variable rates within a fortnight, and investor pricing moved further than owner-occupier pricing on a spread basis. For a marginal buyer running serviceability at the 3 percentage point APRA buffer, the assessment rate climbed from about 9.15% to 9.40%. That trimmed maximum borrow.

Two, the federal budget on 12 May reset the tax rules. Negative gearing on established dwellings closes from 1 July 2027, and the CGT discount drops from 50% to 25% for purchases settled after 12 May 2026. New builds retain both concessions. That single announcement redirected a chunk of the pipeline from established-stock buyers to new-build buyers, and stalled a chunk of the pipeline entirely while landlords reworked their after-tax modelling.

Three, the APRA 6x DTI cap started rationing the top of the borrowing distribution. APRA activated the cap on 1 February 2026. Banks now have to hold new mortgage flow at DTI of six times gross income or higher to a maximum of 20% of new lending, measured quarterly and applied separately to the owner-occupier and investor portfolios. In the March quarter, high-DTI lending was running at roughly 5.5% to 7% of new flow, well inside the ceiling. In the June quarter, the mix moved. The share of new investor loans at 6x DTI or higher pushed above 10% by lender reporting we saw through the quarter, and multiple Big 4 lenders tightened investor DTI credit policy in April and May (Canstar).

The retreat was not evenly distributed. By state, investor commitments by value fell 15.5% in NSW, 14.2% in Victoria and 10.1% in Queensland, on the ABS quarterly detail (Canstar). Those three states are where established-stock investor purchases dominate the pipeline, and where the negative gearing rule change bites hardest.

The existing investor book, on the APRA read#

The new-flow story is one half of the picture. The other half is the stock.

The APRA Quarterly ADI Property Exposures release for June 2026 has investment loans at 31.2% of ADIs' residential property exposures, compared with 30.5% a year earlier. Even as new investor lending retreated in the quarter, the existing investor book grew as a share of the total, because owner-occupier repayments accelerated on higher rates and cleared existing debt faster than new investor loans were replacing it.

Total ADI residential credit outstanding sits at roughly $2.56 trillion, up 7% annually from about $2.39 trillion a year earlier. That is the total mortgage book against which any landlord's individual loan is competing for capital.

Credit quality is the number that surprises. Across the residential book, 1.0% of all loans were non-performing in the June quarter and 0.5% were past due. Both readings are up modestly on the last few quarters. But the composition inside that headline is where the landlord signal sits:

• Non-performing investment loans are lower than owner-occupier loans and flat over the quarter.
• Owner-occupier non-performing loans are edging higher, driven by first home buyer cohorts that borrowed close to the DTI cap through 2023 and 2024 before the cap was in place.
• 60.1% of non-performing loans have an LVR below 80%, on the APRA cut, which points to cash-flow shock (rising rates against fixed household budgets) rather than negative equity (falling values against a stretched borrow).

Three quarters ago, the story was that investor loans were the risk. On the current data, the opposite is holding. Rents up 5.7% year on year on the Cotality August index, a 1.3% national vacancy rate on SQM's July release, and interest deductibility on the investor loan side have combined to protect the servicing schedule. Owner-occupiers cannot pass a rate rise through to a tenant. Investors partly can.

What that means for a landlord's next borrow#

The June data does not mean the market is friendly to new investor borrowing. It means the composition of the constraint has changed.

If your DTI sits under 6x, the cap does not touch you. The retreat in investor lending is not about approval rates for well-structured borrowers on strong income. It is about the top of the DTI distribution getting rationed. A household earning $200,000 gross with a $700,000 PPOR loan carries about $500,000 of investor headroom before the DTI line brushes 6x. That is where the majority of investor buyers still sit.

If your DTI sits above 6x, the borrow is now a portfolio conversation. The Big 4 measure high-DTI share differently. NAB's investor desk has run tighter this year, ANZ's has more headroom, Macquarie and ING tend to sit tighter on investor DTI than the Big 4. Your loan sits in different quartiles of different banks' portfolios, and the same borrow can clear one lender's residual room and fail another's inside the same week.

If the target property is a new dwelling, the DTI cap carves you out. APRA's activation statement exempts loans for the purchase or construction of new dwellings, and the 1 July 2027 negative gearing rule also carves out new builds. Both settings push a marginal investor into house-and-land, off-the-plan and build-to-hold structures.

Interest deductibility still softens the cost of a higher rate. Interest on a loan used to acquire or hold an income-producing property is fully deductible in Australia (ATO rental expenses guide). At a 37% marginal rate, every $1,000 of interest cash cost returns about $370 at tax time. That is what keeps investor non-performing loans lower than owner-occupier, and it is what will keep the existing landlord book resilient into a possible 4.60% cash rate.

The RBA sits over the top of all of it#

The Board meets on Tuesday 29 September at 2:30pm (RBA calendar). Markets are pricing an 82% probability of a 25 basis point hike to 4.60%, on the Aussie tracker. Economist consensus is the other way: 10 of 12 tracked economists expect a hold at 4.35%. NAB is the lone Big 4 tipping a September move; CBA, Westpac and ANZ each see November. Either way, the November interbank contract implies 4.60%, so the full hike is priced by end-November regardless of the timing.

The transmission into landlord cash flow is well understood. A 25 basis point rise adds about $91 a month to a $600,000 investor loan on Canstar's calculator (Canstar). That is $1,092 a year on cash cost, or about $688 a year after a 37% marginal-rate tax refund. It does not sink a well-underwritten book. It does move the marginal decision on whether to refix.

On the last data point that speaks to the demand side, Cotality's preliminary auction clearance rate for the weekend of 20 to 21 September was 54.0%, down from the mid-60s where the spring campaign started. Auction volume rose 15.6% over the week alongside worsening interest rate expectations. That is what the June quarter investor pullback looks like on the ground: more homes going up for auction, fewer buyers holding a hand up.

The practical checklist for this week#

Seven days from the Board decision. Five items to run through:

• Refresh the pre-approval on September policy. Investor DTI thresholds and price bands have moved twice since April. A pre-approval issued in June is now indicative, not binding.
• Get three written variable rate quotes by Friday: one Big 4, one second-tier (Macquarie, ING, Bankwest), and one broker channel. Use them as ceiling references, and treat any 5-handle as perishable inventory. Macquarie's 70% LVR one-year investor fixed at 5.49% is at the sharp end.
• Check the property's dwelling status. New builds sit outside the DTI cap and inside the post-1 July 2027 negative gearing eligibility. Established stock sits inside the cap and outside the eligibility window from that date.
• Model both the 4.35% hold and the 4.60% hike through the Propkt mortgage calculator. A 25 basis point swing changes annual holding cost on a $600,000 investor loan by about $1,092 pre-tax. It changes the marginal negative-gearing loss by less than that on a 37% marginal rate.
• Line up strata, land tax and insurance for the September quarter. State land tax notices are dropping through the quarter, including the QLD 2026-27 assessments, and the timing of settlement moves your first assessed year.

The read for a landlord holding today#

If the loan is already in place and the rent is compliant with state rules, the June data is quietly good news for the existing landlord book. Non-performing investor loans below owner-occupier, and flat over the quarter, is not a signal of a market cracking. It is a signal of a book absorbing the rate cycle better than most commentary expected.

If the loan is about to be written, the June data is a warning. The pipeline has thinned by more than $4 billion in a quarter. That is not just a headline. It is banks pricing DTI risk into approvals, borrowers running the after-tax maths on established stock and pausing, and the nine lenders that lifted fixed rates in September pulling the pricing edge closer to the roof.

Track the numbers at Propkt#

The DTI cap shapes the next borrow. The rate cycle shapes the monthly repayment. The rent side of the yield line shapes what the property earns. Propkt gives Australian landlords a single place to track loan repayments, log compliant expense receipts against the ATO rental schedule, record rent reviews, and run mortgage scenarios at both the current 4.35% cash rate and a possible 4.60% terminal read after 29 September. If the pre-approval is being refreshed this week, set the target property up in Propkt as an active watchlist entry so the first month of holding costs and interest is captured against the correct financial year the moment contracts exchange.
