Australia-Wide Investment Pulse October 2026
Reading time 10 minutes
by Parker Hadley
Cotality’s national Home Value Index fell 1.1% in September. It was the sixth consecutive monthly decline, leaving national values 5.2% below their March peak and flat over the year.
The slowdown is no longer a Sydney and Melbourne story. Brisbane recorded the largest capital-city fall in September at 1.5%, Sydney fell 1.4%, Melbourne eased 0.7%, and Adelaide, Perth and Canberra each fell by more than 1%. Darwin was the only capital to avoid a monthly decline, rising 0.4%.
At the same time, the RBA lifted rates again. Cotality estimates the four increases since February have reduced borrowing capacity for a median-income household by almost $90,000, or around 9%.
For investors, this creates more available stock and fewer competing transactions. It also raises the cost of being wrong. October is not a clean opportunity to buy the dip. It is a better environment in which to test price, cash flow, tenant depth, future resale demand and the investor’s ability to hold the asset when the next six months are less exciting than the last five years.

The national picture in one table
| Signal | October read | Why investors should care |
|---|---|---|
| National values | -1.1% in September; -5.2% from peak; 0.0% annually | The downturn is established rather than theoretical, but the national figure still hides very different starting points and property-level outcomes. |
| Capital-city spread | Brisbane -1.5%; Sydney -1.4%; Melbourne -0.7%; Darwin +0.4% | The earlier mid-sized-market resilience is weakening. Momentum alone is a less useful reason to choose a market. |
| Borrowing capacity | Almost $90,000 lower since February for a median-income household | A smaller ceiling changes market, suburb and property-type options before the search begins. |
| Sales activity | National quarterly sales -19.1% year on year | Fewer transactions can improve negotiation, but they also signal weaker liquidity and require more care with future resale assumptions. |
| Advertised supply | Capital-city new listings -9.2% year on year; total inventory +23.1% | Stock is building because sales have slowed faster than new listings. Investors can filter harder rather than buying whatever appears. |
| Rental conditions | +5.9% annual rents; 1.6% vacancy; $705 median weekly rent | Rental supply remains tight, but affordability and higher ownership costs mean current rent should be used without heroic growth assumptions. |
| Resale outcomes | 95.4% of June-quarter resales profitable; $371,000 median gain | Long holding periods still protect many owners, while recent buyers and weaker property types are more exposed as values fall. |
All figures are from Cotality releases available at 1 October 2026. Different reference periods are retained rather than combined into a false single-month measure.
October turned uncertainty into hard numbers
September began with investors wondering whether the downturn would keep spreading and whether the RBA would move again. By October, both questions had clearer answers.
Values have now fallen nationally for six months. Cotality found 97% of capital-city suburbs recorded declines over the three months to September. Brisbane, Adelaide and Perth, which entered the downturn later than Sydney and Melbourne, are no longer sitting outside the adjustment.
The latest rate increase matters twice for investors. It reduces the amount some buyers can borrow, and it increases the holding pressure on the debt they do take on. Cotality estimates purchasing power for a median-income household has fallen about 9% since February.
A lower purchase price helps at the front end. It does not automatically offset a higher interest bill over the years that follow. That is why the October opportunity needs to be assessed as an ownership decision, not just an acquisition discount.
The strongest city is no longer the useful first question
Perth and Darwin still show double-digit annual growth, while Sydney and Melbourne are negative over the year. Regional values are up 5.6% annually, compared with a 1.8% fall across the combined capitals. Those comparisons are real, but they are backward-looking descriptions of different cycles.
The better first question is what the investor’s current budget, holding capacity and risk tolerance can buy in each market now.
A strong annual result can sit beside weakening monthly momentum. A deeper correction can create a better entry, but only if the market, suburb and property still have durable demand. A smaller market can offer yield and scarcity, but also thinner resale liquidity and greater exposure to one employer, industry or supply response.
Our guide to choosing an Australian investment market starts with the investor rather than the hotspot. October makes that discipline more important, not less.
More stock should raise the property standard
Across the combined capitals, total inventory was 23.1% higher than a year ago even though new listings were 9.2% lower. National sales over the latest three months were 19.1% below the same period last year, and capital-city homes were taking a median of 39 days to sell compared with 23 days a year earlier.
This is a buyer-friendly supply pattern, but it needs to be read correctly. The market has not suddenly produced 23% more fresh, investment-grade stock. More homes are accumulating because the rate of sale has slowed faster than new supply.
Use the extra choice to reject more. Long time on market, repeated relaunches and vendor adjustment can improve the price, but they can also reveal that the asset has a narrow tenant or future-buyer pool.
Separate a stale campaign from a stale asset. The first can be a negotiation opportunity. The second can remain difficult to lease, finance, maintain or resell after the purchase excitement has gone.
Let supply improve due diligence. A broader set of comparable listings and sales should make price, rent and property-quality assumptions easier to challenge.
The holding test is now part of asset selection
The rate rise does not make every negatively geared property unsuitable, and it does not make the highest-yield property safest. It means the investment brief needs an honest holding test before the suburb search starts.
| Holding test | Question to answer before buying | Why it matters now |
|---|---|---|
| Finance | What is the current borrowing limit and repayment range after the September increase? | A pre-approval or cash-flow model from earlier in the year may no longer describe the real decision. |
| Rent | What is achievable today, after management, vacancy and property-specific competition? | Tight national rental conditions support the hold but do not guarantee the top appraisal or uninterrupted occupancy. |
| Costs | Can the investor absorb insurance, rates, maintenance, strata or land-tax changes without depending on immediate growth? | Higher debt cost leaves less room for underestimated ownership expenses. |
| Time | Can the property be held through several quiet years without forcing a sale? | Cotality’s resale data shows shorter holding periods are more exposed when a downturn arrives. |
| Exit | Who is the likely future buyer if investor demand weakens? | A broad owner-occupier and investor pool can support resale depth when finance and sentiment are less generous. |
Resale profits explain why time and property type matter
Cotality’s June-quarter Pain and Gain analysis found 95.4% of Australian resales still produced a nominal gain. The median gain was $371,000, down from $378,000 in March. That remains a strong historical result, but the direction has changed as the downturn begins to feed into actual sales.
Time in the market provided meaningful protection. Profitable resales had been held for a median 9.1 years, compared with 8.1 years for loss-making resales. The difference was sharper for houses: profitable house resales were held for 9.3 years, while loss-making houses had typically been held for 4.4 years.
Property type mattered too. Houses produced a nominal gain in 97.8% of resales, compared with 90.5% for units. Sydney and Melbourne together accounted for 83.3% of the value of unit resale losses nationally.
The lesson is not that every house is better than every unit. It is that holding time cannot rescue an asset whose supply, building, layout or buyer pool was weak from the beginning. The property still needs to work for a tenant now and for a future buyer later.
Our recent article on owner-occupier appeal in investment property looks at that second audience in more detail.
Markets on our radar
This is a research direction, not a shopping list. Market data narrows where to investigate. It cannot select the suburb, street or asset.
| Market lane | Latest Cotality read | What we would investigate | What we would resist |
|---|---|---|---|
| Sydney and Melbourne | September -1.4% and -0.7%; annual -7.0% and -6.2% | Scarce, owner-occupier-grade assets where the correction has improved the entry and the future buyer pool remains broad. | Buying a compromised unit or expensive holding position because the city is down from peak. |
| Brisbane Adelaide and Perth | All fell by more than 1% in September; Perth still +10.1% annually | Established family assets where slower demand and more stock create better comparison without relying on fringe supply. | Anchoring to the previous boom, treating every discount as value or assuming the strongest annual city will remain the strongest. |
| Darwin | +0.4% in September; +11.9% annually | Assets with a clear tenant profile, sensible insurance and a resale pool that is not dependent on one narrow demand source. | Chasing the only positive monthly capital without pricing market size, volatility and local economic concentration. |
| Regional markets | +5.6% annually versus -1.8% across combined capitals | Affordable centres with diverse employment, durable services, rental depth and an asset that local owner-occupiers may want. | Treating regional resilience as universal or ignoring employment, insurance, climate and resale-liquidity risk. |

Rents help but they are not the whole buffer
Cotality’s latest national rental review recorded 5.9% annual rent growth, a median dwelling rent of $705 per week and a 1.6% vacancy rate. Rental listings were 16.7% below the five-year average. Those conditions remain supportive for landlords.
They do not remove the need for a conservative property-level rent. National rental growth can sit beside a local market where the advertised appraisal is too optimistic, new supply is arriving or the tenant pool is thinner at a particular price point.
We would model the achievable rent today, allow for vacancy and management, include real ownership costs and then test the result at a harder finance setting. If the property only works when rent immediately reaches the best comparable and rates quickly reverse, the buffer is doing too much imaginary work.
For first-time investors, our Property Investing 101 guide explains how the goal, budget, cash flow and risk settings should shape the market and property brief before the search begins.
Three rules for October
A falling market can improve the entry. It cannot make the holding cost irrelevant.
More advertised stock can improve selection. It cannot turn a stale property into a scarce one.
A long holding period can absorb several market cycles. It cannot compensate for buying the wrong asset at the wrong price with no buffer.
What we are not doing
- We are not calling Brisbane cheap because it had the largest September fall.
- We are not calling Sydney and Melbourne automatic buys because they are further below peak.
- We are not chasing Darwin because it was the only capital to rise in September.
- We are not using national rental growth as the rent forecast for an individual property.
- We are not lowering the asset standard simply because more vendors are negotiable.
- We are not mixing data providers to create a more dramatic market ranking.
Our take
The interesting thing about October is not that prices are falling. It is that the easy stories are falling apart too.
The strongest city can weaken. The city with the largest correction can still contain poor assets. A high rent can disappear into finance, insurance and maintenance. A discount can be real and still not be enough.
This is a useful market for investors who can hold their nerve and their property. Confirm the finance, keep the rent boring, reject more of the stock and make sure the future buyer is visible before the offer goes in. More choice should make the property better, not the explanation longer.
