Buried in Cotality's July Home Value Index is one of the most confronting numbers I've seen in years of reading these reports: of the thousands of suburbs the researchers track nationally, just 0.8% — roughly 38 suburbs — would deliver positive cash flow for a new investor today. Everywhere else, the rent doesn't cover the costs. Cotality's own researchers called it "a needle in a haystack".
Thirty-eight suburbs, in an entire continent. And when you see where they are, the picture gets stranger still. But the real story isn't the number itself — it's what that number tells you about how Australian property investing has actually worked for the past two decades, and why the rules of that game are now being rewritten.
The maths that stopped working
Cotality's modelling is straightforward: a 20% deposit, a 30-year principal-and-interest loan at the market-average investor rate of 6.34%, and holding costs (insurance, rates, maintenance, management) of 2.5% of the property's value. Run those numbers across the country and almost nothing passes.
The reason is a simple gap. Gross rental yields across the combined capitals average 3.50%. Investor mortgage rates are sitting around 6.4%. The income side of the ledger starts nearly three percentage points behind the biggest single cost — and the mortgage makes up 71% of a typical investor's total expenses. In Sydney and Brisbane, gross yields are just 3.3%. Melbourne does slightly better at 3.9%. None of it comes close to covering a leveraged purchase.
"Yields will need to rise significantly before rental income comes close to outweighing holding costs for a leveraged investor," said Cotality research director Tim Lawless.
Where the 38 suburbs are — and why that's a warning, not a shopping list
Of the 38 suburbs that do pay their own way, only two are in capital cities: Carlton in Melbourne (units) and Berrimah in Darwin (houses). Around 69% are in regional WA — heavily skewed to Pilbara mining towns — and another 10% sit around Queensland's Bowen Basin coal region.
In other words, the "cash flow positive" map of Australia is essentially a map of mining towns. These are markets where yields are high precisely because prices carry real risk: single-industry economies, boom-bust price histories, and lenders who often apply tougher terms to them. High yield is not free money — it's the compensation the market demands for volatility. If a suburb pays 8% while the rest of the country pays 3.5%, the first question should always be "what does the market know about this place that the yield is pricing in?"
The subsidy that made losing money tolerable is ending
Here's the strategic centre of this story. For decades, the answer to "why would anyone buy an asset that loses money every year?" was negative gearing: the annual loss was softened at tax time, and the real payoff came later as a capital gain, taxed at a discount. Negative cash flow wasn't a bug — it was the accepted price of admission.
The 2026 Federal Budget changed that equation. For established properties purchased after 7:30pm on 12 May 2026, rental losses can no longer be deducted against salary or other personal income from 1 July 2027. Losses can only be carried forward against future rental income or capital gains. Existing holdings are grandfathered until sold, and eligible new builds keep both negative gearing and the 50% CGT discount.
Put the two facts together and the picture sharpens: 99.2% of suburbs produce a yearly loss for a new leveraged investor, and for newly purchased established homes, that loss is about to lose most of its tax shelter. An investor buying an established property today needs the numbers to work on their own merits — and in 38 suburbs out of thousands, they do.
The market is already responding
You can see the adjustment happening in real time, from two directions at once.
On the income side, yields are quietly rising. Rents grew 5.9% nationally over the year to June — about $40 a week on the median — against a national vacancy rate of just 1.6%, well below the decade average of 2.5%. With home values now falling in Sydney and Melbourne while rents keep climbing, gross yields across the combined capitals have lifted from a record low of 2.92% in January 2022 to 3.50% today. That is the market slowly repricing property back toward income fundamentals.
On the demand side, investors are stepping back. ABS lending data for the March quarter showed new investor loan numbers down 5.3%. AMP's chief economist has suggested the tax changes alone could shave around 5% from prices as investor demand retreats. Lawless makes the forward-looking point: higher yields "might help motivate investors into the established housing market without the crutch of negative gearing" — but that repricing has a long way to run.
What to actually do with this
If you're weighing up an investment purchase — or holding one and wondering what the new world means — this is how I'd think it through:
- Run the cash flow before you fall in love with the growth story. Our investment cashflow calculator lets you test any property against real rates, rents and holding costs — the same style of maths Cotality used.
- Understand which tax regime your purchase falls into. Established post-May 2026, established grandfathered, or new build — three very different after-tax outcomes for the same headline price.
- Don't chase yield into markets you don't understand. A Pilbara yield comes with Pilbara risk. If the cash flow only works in a town with one employer, the cash flow is not the whole story.
- Structure matters more when there's no tax cushion. The gap between an average investor rate and a sharp one is pure cash flow now. So are offset accounts, interest-only periods and lender selection — the things a broker works on. Our investment loans page covers the moving parts.
- If you hold a grandfathered property, the exit decision got heavier. Selling doesn't just crystallise a gain or loss — it permanently surrenders a tax treatment you can't buy back. Model that before listing.
Frequently Asked Questions
What does cash flow positive mean in property investing?
A property is cash flow positive when the rent it earns covers all of its costs — mortgage repayments, insurance, rates, maintenance and management fees — with money left over each year. If the costs exceed the rent, the property is cash flow negative and the owner tops up the difference from their own income.
How many suburbs in Australia are cash flow positive in 2026?
Cotality research from May 2026 found only about 38 suburbs — roughly 0.8% of the suburbs analysed nationally — would deliver positive cash flow for a new investor, assuming a 20% deposit, a 30-year principal-and-interest loan at 6.34% and holding costs of 2.5% of the property's value. Only two were in capital cities: Carlton in Melbourne (units) and Berrimah in Darwin (houses).
Can I still negatively gear an investment property in Australia?
It depends on when you bought. Properties held before 7:30pm on 12 May 2026 are grandfathered and can continue to be negatively geared until sold. For established properties purchased after that time, rental losses can no longer be offset against salary or other personal income from 1 July 2027 — they can only be carried forward against future rental income or capital gains. Eligible new builds keep full negative gearing and the 50% CGT discount.
Are rental yields rising in Australia in 2026?
Yes. Because rents are rising faster than home values, gross rental yields across the combined capital cities reached 3.50% in June 2026, up from a cyclical low of 3.34% in December 2025 and a record low of 2.92% in January 2022. National rents rose 5.9% over the year to June 2026, about $40 a week on the median rent.
Does negative gearing still apply to new builds after the 2026 Budget?
Yes. Eligible newly built residential properties are exempt from the 2026 Budget changes. Investors who buy a qualifying new build can still deduct rental losses against their other income and still access the 50% capital gains tax discount. This is a deliberate design choice to steer investor capital toward adding new housing supply.
