Key takeaways
- Cotality's June 2026 Home Value Index had the national index down 0.4% for the month, the largest single-month fall since December 2022. Sydney fell 1.2%, Melbourne 1.0%, ACT 0.6%.
- Over the June quarter, capital city home values fell 1.3% overall, with Sydney down 3.2% and Melbourne down 2.6%. Auction clearance rates have sat below 50% since late May and capital city sales are down about 16.2% year-on-year.
- ABS Building Approvals for May 2026, released 1 July 2026, had total dwellings down 1.1% to 17,019. Private houses were up 2.8% to 10,537 but private dwellings excluding houses fell 10.4% to 6,034. Apartments on the original series were off around 30% for the month.
- Non-residential building value rose 41.0% to a record $10.83 billion on data centre approvals in NSW and Victoria, moving above the total residential building value of $10.24 billion for the month.
- Rents kept climbing. Annual rent growth is running at about 5.9% with the SQM Research national vacancy rate at 1.2% on the most recent monthly read. Gross rental yields across the combined capitals have lifted to about 3.45%, the highest since mid-2025.
- The RBA held at 4.35% on 16 June and next meets on 11 August 2026. The buying window in Sydney and Melbourne is genuinely wider than it has been since late 2024. The rental supply pipeline behind it looks worse, not better.
June was the biggest single-month fall in three and a half years
Cotality's June 2026 Home Value Index landed on Tuesday 1 July 2026 with a national reading of minus 0.4% for the month. That is the largest single-month decline in Cotality's national index since December 2022, when the market was in the depths of the RBA's initial tightening cycle. It is the fifth consecutive monthly decline for Sydney, the sixth for Melbourne, and the reading arrived at the same time that the ABS Building Approvals release for May 2026 confirmed apartment approvals are still going in the wrong direction.
Capital city breakdowns for June, from the Cotality release:
- Sydney: -1.2%
- Melbourne: -1.0%
- ACT: -0.6%
- Hobart: broadly flat
- Adelaide: 0.0% (unchanged)
- Brisbane: +0.3%
- Perth: +0.7%
The mid-sized capitals that carried the national index through 2024 and 2025 have effectively stopped growing. Brisbane's 0.3% and Perth's 0.7% are the weakest single-month readings for both markets since 2023. Adelaide has now printed a flat month for the first time in more than two years.
The June quarter numbers are the ones that matter for anyone assessing equity in a Sydney or Melbourne investment property:
- Capital cities aggregate: -1.3%
- Sydney: -3.2%
- Melbourne: -2.6%
- ACT: -1.3%
For a landlord who bought a Sydney investment property for $1.2 million in March 2026 with a 20% deposit, the June quarter has moved paper equity from $240,000 to about $201,600 on the index read. The mortgage sits where it sat. The rent, we will come back to, has moved the other way.
Cotality's Research Director Tim Lawless linked the June softness to a combination of affordability constraints, cost of living pressures, weak consumer sentiment and property taxation changes announced in state budgets. Two of those levers, taxation and sentiment, are the ones Propkt has covered in detail over recent weeks: the NSW Budget 2026-27 froze the general land tax threshold at $1,075,000 for a third year and the ATO's General Interest Charge went non-deductible from 1 July 2025 at a headline rate that has since stepped to 11.43% from the start of this financial year.
Under the surface, rents are still doing the work
The story that does not show up in the front-page price number is the rental picture on the same asset.
National annual rent growth is running at about 5.9% on the SQM Research read for the most recent monthly cycle, roughly two and a half points above wage growth. Gross rental yields across the combined capitals have expanded to about 3.45% on the latest Cotality yield data, the highest reading since mid-2025. Vacancy sat at 1.2% nationally on SQM's most recent monthly print, well below the 2.5% to 3.0% band that economists use as a marker for balanced conditions.
Yield expansion in a falling values environment is a specific arithmetic outcome. Rent is the numerator, value is the denominator. When rent is rising and value is falling, gross yield lifts on both sides of the ratio. For an investor buying today rather than a year ago:
- The entry price is 3% or so lower in Sydney and Melbourne.
- The holding rent is 6% higher.
- The operating cost base (rates, insurance, land tax, GIC exposure on any tax debt) is a few percentage points higher than it was a year ago.
The net cash flow position on an equivalent asset acquired at today's price and today's rent, on a today-terms loan, is materially better than the same asset acquired at the November 2025 peak. That is not a headline the sentiment surveys pick up.
The gap between segments is worth naming. On Cotality's national breakdown:
- Units are running at about 4.3% gross yield.
- Houses are running at about 3.0% gross yield.
That 130 basis point premium is the widest unit-versus-house yield gap Cotality has printed in modern history. For a new investor working a servicing calculator, the unit yield closes the servicing shortfall on a typical Big 4 investor loan by roughly $150 to $200 per week on a $700,000 borrow. The tradeoff is capital growth exposure. Units historically underperform houses on the value line by about a percentage point a year over a full cycle.
The supply side is where landlords should look next
The May 2026 ABS Building Approvals release, published on 1 July 2026, landed hardest on the numbers that matter for rental supply into 2027 and 2028.
Dwelling approvals fell 1.1% in seasonally adjusted terms for the month, to 17,019 dwellings. That top-line number understates the split.
- Private sector houses: +2.8% to 10,537 approvals.
- Private sector dwellings excluding houses: -10.4% to 6,034 approvals.
- Apartments only, original series: down about 30% to 2,877 dwellings.
The rental market runs on the second line, not the first. Detached houses are overwhelmingly owner-occupied or built as principal residences. Apartments, townhouses and unit blocks are the shape of stock that fills rental listings in Sydney, Melbourne, Brisbane and Perth. That segment has now printed a double-digit monthly decline in seasonally adjusted terms.
State reads for the month:
- New South Wales: +2.2%
- South Australia: +10.9%
- Tasmania: +4.8%
- Western Australia: -1.3%
- Victoria: -3.0%
- Queensland: -8.8%
The rebound in South Australia and Tasmania is off small denominators. Victoria and Queensland are the two states where the drop is meaningful in raw dwelling terms, and both are markets running hot rental markets on the demand side.
The value picture is the tell:
- Total residential building value: -5.7% to $10.24 billion.
- Total non-residential building value: +41.0% to a record $10.83 billion.
Non-residential building value moved above residential building value for the month, an inversion that reflects two large data centre approvals in New South Wales and Victoria dominating the release. For a landlord, the practical effect is that the concrete, steel, formwork subcontractors and crane fleets that a residential apartment developer competes for are being drawn into hyperscale data centre projects backed by sovereign wealth capital. Construction cost pressure that flowed through the 2023 to 2025 apartment pipeline is not resolving. It is being reallocated.
Propkt covered the same data-centre-versus-housing capacity story from the Q1 2026 GDP release earlier in the cycle. The May 2026 building approvals release is the first data print that shows the reallocation happening at the approvals stage rather than only in the completions numbers.
What the June turn changes for a leveraged landlord
Six practical shifts land on the landlord ledger from the June data set.
1. The buying window in Sydney and Melbourne has opened. Auction clearance rates have sat below 50% since late May on Cotality's national measure and capital city home sales are down about 16.2% year-on-year. Advertised stock in Sydney and Melbourne has lifted. A buyer with a specific asset thesis has more room to negotiate today than at any point since late 2024. The reliable acquisition rule holds: the asset needs to work at today's rents and today's rates, not on the assumption of near-term index recovery.
2. Yields have quietly expanded. Gross yields on the combined capitals at 3.45% are the highest since mid-2025. On a $700,000 investor loan at a 6.20% variable rate, an extra 20 basis points of gross yield closes about $60 per week of the after-tax cash flow gap on a typical Sydney unit purchase. The gap is not closed. It is narrower.
3. Rents are not rolling over. The 5.9% annual national rent growth reading arrived while values were falling for the fifth consecutive month in Sydney. Rents are not tracking capital values on a lagged basis. They are tracking absolute rental supply, which the May approvals data suggests is going to stay tight through the back half of 2026 and into 2027.
4. The RBA is on hold, but the direction is unclear. The RBA held the cash rate at 4.35% on 16 June 2026 and does not meet again until 11 August 2026. The forward view splits: CBA and ANZ expect the next move to be a cut but not until 2027, NAB has pushed its first cut call into the June quarter of 2027, Westpac still has two more hikes to 4.85% by September 2026 in its formal forecasts. A leveraged landlord planning cash flow into December should model 4.35% held as base case and a single 25 basis point rise as the reasonable risk case.
5. Fixed rate refinancing is more expensive than it was in late 2025. The Big 4 have all repriced fixed rates up over the first half of 2026, with Westpac lifting one-year fixed investor rates by up to 0.50%, and CBA and NAB adding 0.30 to 0.35 percentage points across their fixed suites. Any investor loan sitting on a rate more than 40 basis points above the sharpest advertised equivalent is a straight-line refinance opportunity that lifts pre-tax cash flow immediately.
6. Supply for rentals is worse, not better. The 10.4% monthly fall in private dwellings-excluding-houses approvals is a rental supply story, not a headline housing story. The federal government's National Housing Accord target of 1.2 million new homes over five years to mid-2029 sits well ahead of the current run rate, and every monthly release that misses the required pace pushes the shortfall wider. For a landlord, that math sits under the rent line.
The federal and state overlay is still tightening
Behind the market data, the policy settings for landlords are moving in one direction across the states.
Foreign purchaser rules are broadly holding at surcharge levels well above domestic buyer rates, with NSW carving out an exemption for build-to-rent transfers above 50 dwellings from 1 July 2026. The domestic single-property investor sits outside that carve-out.
Land tax thresholds in NSW remain frozen at $1,075,000 for a third year. Victoria's temporary COVID debt land tax levy remains in place. Queensland's absentee owner surcharge and land tax rules continue to catch cross-border portfolios. Land tax bills sitting on 30 June 2026 balances are being issued now.
Tenancy law reforms rolled through 2026 in NSW (no-grounds evictions ended May 2025), Tasmania (Pets Act took effect 20 March 2026) and Victoria. The compliance load is up. The re-let trap for landlords who list, do not sell at reserve and then reset back to lease is genuine.
ATO enforcement on rental returns is running through three concurrent data-matching programs covering approximately 1.7 million investor loans, 2.3 million property management records and 2.2 million rental bonds through to 30 June 2026, with Assistant Commissioner Rob Thomson continuing to flag that around nine in ten landlord returns contain errors.
The overlay is a slow tightening on effective after-tax cash flow, at the same time the market data is delivering yield expansion at the acquisition level. The two effects run against each other. The landlord who is running a clean deduction record, a serviceable loan structure and a realistic view of rent growth is better positioned to take a Sydney or Melbourne opportunity in July than the landlord waiting for an all-clear signal.
Positioning the second half of 2026
A short read on the base case, the risk case and the pivot points for the balance of 2026.
Base case. Sydney and Melbourne extend the current slide for another two to three months on the Cotality read, before finding a floor around late Q3 as auction clearance normalises. Perth, Brisbane and Adelaide continue to flatten but avoid negative monthly prints. National rent growth eases slightly from 5.9% but stays above 4%. The RBA holds through August, and the next move is a cut in Q1 or Q2 2027. Gross yields expand modestly. Non-residential building continues to draw construction capacity from the residential pipeline.
Downside risk case. Westpac's forecast comes true and the RBA lifts to 4.60% in August and 4.85% by September. Sydney and Melbourne extend the current slide into a double-digit peak-to-trough drawdown. Fixed rates on investor loans reprice higher. Highly leveraged investors sitting at 90% LVR on late 2024 purchases face genuine equity stress. Rents keep rising because supply does not care about interest rates.
Upside risk case. The June quarter turn convinces the RBA to sit longer and cut earlier. Sydney and Melbourne stabilise faster. The 5.9% rent growth eases as rental affordability caps hit ceiling. Yields tighten again from the top.
The landlord decisions that make sense in all three cases:
- Review your loan mix now, not in September, for anything sitting on legacy Big 4 pricing.
- Reconcile FY26 rental deductions carefully into the September 2026 lodgement window given the ATO data-matching net.
- Do not confuse the front-page dwelling values headline with the rent line on your specific asset. The two are running in opposite directions in Sydney and Melbourne right now.
For readers building the specific numbers into their own portfolio view, Propkt's mortgage calculator runs the servicing math on today's Big 4 investor rates, the expense tracker captures the FY26 deductions that the ATO's three data-matching programs are cross-checked against, and the rent management flow keeps the annual rent review record straight for whichever state's tenancy rules apply to your title.
Six weeks to the next RBA decision. The June quarter data has moved the ground. The rents did not get the memo.
