Key takeaways
- Fresh Sydney listings are roughly 14% below the five-year seasonal average for the four weeks to 23 August 2026, Melbourne about 9% below and Brisbane about 5% below (Real Estate Business, 25 August 2026).
- Cotality's rolling four-week HVI measure to 10 August 2026 has every major capital in negative territory: Sydney -1.4%, Melbourne -1.0%, Brisbane -0.5%, Adelaide -0.3%, Perth -0.3% (Cotality Monthly Housing Chart Pack, August 2026).
- Annual dwelling value growth has slowed to 5.3% nationally, with Sydney down 2.0% and Melbourne down 2.8% on the year to August 2026.
- Sydney's HVI is roughly 6.7% below its peak and Melbourne's is about 6.2% below on Cotality's daily index measure through August (MacroBusiness summary of Cotality August daily HVI).
- The August Chart Pack models 5%, 10%, 15% and 20% peak-to-trough scenarios. A 20% Sydney fall resets values to about May 2021. A 10% Melbourne fall resets to pre-pandemic.
- Vendor discounting has widened to about 3.6% median across the combined capitals and days on market has stretched to 30 days across the capitals and 36 in the regionals, per the 16 August auction wrap.
- Rent growth is the offset: Cotality has annual rent growth at 5.9% and the median national rent at a record $705 per week (Cotality Q2 2026 Quarterly Rental Review).
- SQM national vacancy sits at 1.3% in July 2026, with Sydney at 1.4% and Melbourne at 2.0%. Brisbane, Perth, Adelaide, Hobart and Darwin are all sub-1%.
- Sydney existing total listings are still tracking about 28% higher year-on-year and Melbourne total stock about 42.8% higher on the SQM July count, so the subdued fresh flow overlays a real existing stock overhang.
- The 29 September RBA decision is the next scheduled shock the market has to price. ASX futures currently price a 17% chance of a 25bp hike and a 77-88% chance of a hold at 4.35%, per the 27 August CPI wrap.
- For a landlord, the operational answer is: refresh the desktop valuation now, run the rent review off the WPI-to-market band, and take the softer transaction data into the retention conversation with the current lender.

What has actually opened the spring calendar#
Spring in the Australian property calendar starts Monday 1 September. The four-week window before that opening bell is the read that agents, valuers and investors use to size the season. That read for spring 2026 is soft.
Fresh listings coming onto the market for the four weeks to Sunday 23 August ran below the five-year seasonal average across three of the four east coast capitals. Sydney fresh listings sat roughly 14% below average, Melbourne about 9% below, and Brisbane about 5% below (Real Estate Business summary of Cotality's four-week listings data, 25 August 2026). Fresh listings capture the vendors who have signed an agency agreement in the last 28 days. The number strips out the tail of stale stock that has been sitting on realestate.com.au since autumn.
The subdued fresh flow is the signal. It says vendors who have a choice about when to sell are choosing not to campaign the property into spring right now. On the buyer side, Cotality's Property Market Indicator Summary for the week ending 16 August 2026 reported the same softer conditions across preliminary clearance rates and volumes.
The context underneath the listings picture is what makes it a decision, not just an observation.
The four-week HVI has every capital in the red#
Cotality's rolling four-week Home Value Index measure to 10 August 2026 shows every major capital moving lower.
- Sydney: -1.4% over the four weeks
- Melbourne: -1.0%
- Brisbane: -0.5%
- Adelaide: -0.3%
- Perth: -0.3%
That is the first time in more than three years that Perth has been in negative territory on the four-week roll (Cotality Monthly Housing Chart Pack, August 2026). Perth had been the standout capital through 2024, 2025 and into the first half of 2026, printing +26% year-on-year on the May 2026 HVI (Cotality May 2026 HVI). The August roll finally has Perth joining the softer national picture.
Annual growth has slowed to 5.3% nationally, with Sydney down 2.0% and Melbourne down 2.8% on the year to August (Cotality's August analysis on the four-week roll). Sydney and Melbourne are now sitting on 12-month falls at the same time as headline national growth is still positive. That combination is unusual and it explains a lot about vendor psychology going into the spring window.
Sydney is 6.7% below peak, Melbourne 6.2%#
The peak-to-current number is the one that a landlord modelling a spring sale needs on their run sheet.
On Cotality's daily HVI through August, Sydney is roughly 6.7% below its peak and Melbourne is roughly 6.2% below (MacroBusiness summary of Cotality's August daily HVI). Both cities are through the first threshold on Cotality's own scenario table.
The August Chart Pack models 5%, 10%, 15% and 20% peak-to-trough declines for each capital and rolls them back to a matching historical value date. The key readings from that table:
- A 20% Sydney fall returns values to about May 2021, before the pandemic-era boom pushed medians into the $1.6 million range on houses.
- A 10% Melbourne fall returns values to pre-pandemic levels.
- Brisbane, Perth and Adelaide have more buffer, given the run they had between 2023 and mid-2026.
Melbourne having the smallest buffer of any capital is the important read for a landlord holding an inner-city or middle-ring unit. Melbourne unit values did not run as hard through the pandemic as Sydney's did, so a further 4-5% fall from here does more damage to peak-to-trough on the base than the same fall does in Sydney.
Sydney's second read is that the market has already absorbed the equivalent of about a quarter of a full 25 basis point rate hike passing through mortgage repayments in capital value terms, before the RBA has moved a second time.
Vendor discounting is at 3.6% and days on market at 30#
The other two prints landlords need on the run sheet come from the auction and private-treaty data collected through August. Median vendor discounting across the combined capitals has widened to about 3.6% and days on market has stretched to 30 days across the capitals and 36 across the regionals (auction and market data wrap, 16 August 2026).
Both are up materially on the March quarter, when discounting was closer to 2% and days on market was in the low 20s.
The mechanical read for a landlord: a September campaign should be budgeted at 6 weeks from list to unconditional contract, not the 4 weeks that was standard in autumn. Every day on market past the campaign window has a leverage effect on the eventual discount. The vendors that transact closest to the initial list price are the ones whose reserve or asking is anchored on a July or August 2026 comparable, not a January or February one.
Rents are still doing the offset#
The one part of the picture that has not softened is rent growth.
Cotality's Q2 2026 Quarterly Rental Review has annual rent growth at 5.9%, up from 5.7% in Q1, with the median national dwelling rent at a record $705 per week (Cotality Q2 2026 Quarterly Rental Review). SQM Research has national vacancy at 1.3% in July 2026, with Sydney at 1.4% and Melbourne at 2.0%. Brisbane, Perth, Adelaide, Hobart and Darwin are all sub-1%.
The yield mechanics work like this: a Sydney investor property purchased at $1.4 million in early 2024 on a market rent of about $780 a week was carrying a gross yield of roughly 2.9%. Rent growth of about 6% per year across two years lifts the rent to roughly $875 a week. If the same property's capital value is now roughly 4.5% below where it was purchased, the base value is closer to $1.34 million. Gross yield lifts from 2.9% to about 3.4%. That is meaningful yield repair, and it is the actual buffer that has held some Sydney investor cash flow together through the falling-values period.
But it is not enough on its own to move a marginal hold-vs-sell case from held to comfortably held. The maths that decides sell-vs-hold for a Sydney investor property this spring is:
- The pre-tax monthly cash flow on the current variable interest rate (roughly 6.44-6.69% carded on investor P&I) against the current rent, net of body corporate, insurance, rates and management fees.
- The capital growth expectation through the next 12-24 months, benchmarked off Cotality's own peak-to-trough scenarios.
- The tax position on holding, including the deductibility of interest and the changes to negative gearing and CGT settings for existing dwellings from 1 July 2027.
Rent growth of 6% helps line 1. It does not on its own fix a cash flow gap that is a function of a 6.44% investor rate compounding on a big loan balance.
The market read into 29 September#
The next scheduled shock for the market is the RBA Monetary Policy Board meeting on 29 September 2026. ASX 30-day interbank cash rate futures currently price a 77-88% chance of a hold at 4.35% and a 17% chance of a 25 basis point hike, per the ranges published in the 27 August CPI and RBA minutes wrap.
That pricing matters for three reasons this month.
Fixed-rate window. Westpac lifted its fixed home loan and investor rates in the week to 26 August, joining earlier moves from CBA, NAB and ANZ. Standard investor two-year fixed on the Big 4 is now above 6.29% on carded rates. The window for locking a fixed portion of an investor loan below current variable levels is closing.
Retention conversation timing. Existing lenders will hold a competitive discretionary discount on a good landlord file (strong LVR, clean arrears, current property inspection) right up to the Board meeting. That window tightens materially in the 24 hours after any hawkish decision. Booking the retention conversation the week of 15 September is a better outcome than booking it the week of 6 October.
Valuation basis. Ordering a fresh desktop valuation now, with August 2026 comparables in the input data set, means the retention or refinance case is being made on the current market rather than the March market. On a Sydney property, that August-comparable valuation is likely to be 3-4% below where a January valuation would have sat. On the retention conversation that number is leverage for the borrower, not a strike against them.
What a landlord should actually do this week#
Three moves before Friday.
1. Pull the four-week HVI change for each property's actual suburb. The capital city average hides large intra-city variance. Cotality's free suburb-level indices show inner-ring Sydney units running below the Sydney average, while middle-ring houses in some Sydney LGAs are still marginally positive on the four-week roll. That variance changes the sell-vs-hold answer for a specific property.
2. Order or refresh the desktop valuation. The lag between where valuers were carrying stock in March and where the transaction data has moved to in August is now large enough that a stale valuation costs the borrower on both LVR and any discretionary rate. Order the fresh comparable now while August prints are the newest sales in the data set.
3. Run the rent review off the WPI-to-Cotality band. WPI printed at 3.2% for the June quarter and Cotality rents at 5.9%. The defensible rent-review band around 4.0-4.5% sits above WPI and inside CPI-plus-market rent. On a $780-a-week Sydney investor property that is roughly $30-35 a week added on renewal, or about $1,600-1,800 a year of gross rent. On a portfolio of three properties that is the difference between a cash flow gap and cash flow neutral through Q4 2026.
The soft spring is a decision, not an event#
The read from spring 2026 opening is not that the market has broken. It is that fresh listings, fresh sales and fresh capital values are all telling the same slower story at the same time, and that story is heading into a 29 September RBA decision with a hawkish August minutes still fresh.
The landlord decisions available right now are still normal-market decisions: refresh the valuation, book the retention call before the Board sits, run the rent review off the defensible band, and sit down with the tax agent before the next tranche of ATO data-matching pushes into the 2025-26 tax return cycle. The Propkt rent management workflow automates the comparable pull for a rent-review notice, the mortgage calculator runs the pre-tax cash flow across a 25 basis point uplift and, on the expense side, the expense tracker keeps the deductible-interest calculation clean into the 2026-27 return.
Do the operational work in September rather than October. The compound cost of leaving a stale valuation, a stale rent notice and a stale retention discount on the file through the last quarter of the year is the number that shows up in the July 2027 tax return.
