Australia's property investors have just been handed the biggest tax shake-up in decades — and the timing couldn't be worse.

The federal government is scrapping the capital gains tax (CGT) discount from July 2027 and banning negative gearing on established homes. At the same time, the market has already turned: national prices fell 0.7 per cent in July, the biggest monthly drop since December 2022.

So if you're one of the roughly two million Australians who own an investment property, the question keeping you up at night is a simple one with a not-so-simple answer. It's also the question landing in our inbox more than any other right now.

The situation

Take "Mark", a 52-year-old small business owner from Brisbane's outer suburbs who came to us this week.

Mark bought his first investment property in 2014 and added two more over the following decade, negatively geared on all three. Between rate rises and rising holding costs, his portfolio is cash-flow negative by about $1,100 a month — a gap he's been bridging because the end-of-year tax refund made the maths work. Now negative gearing is going, the CGT discount is going, and Brisbane prices have posted their second straight monthly fall.

"I feel like the rules changed halfway through the game," he asked us. "Do I get out before everyone else does, or am I panicking over nothing?"

We get asked this all the time. Here's the answer we gave him.

The question

Should property investors sell now, hold, or buy more — before the CGT and negative gearing changes bite?

The answer

Let's separate the noise from the numbers.

First, the tax changes are real, but not immediate. The CGT discount doesn't disappear until July 2027, and the negative gearing ban applies to established homes — new builds are carved out. That's a window, not a cliff. Investors rushing for the exit this month are responding to a headline, not a deadline.

Second, the "landlord bailout" nobody is talking about. Our research desk has tracked national asking rents rising 39 per cent since May 2022 — the median national dwelling rent has gone from $501.70 to $697.40 a week. The national rental vacancy rate is 1.3 per cent, less than half the 2.8 per cent at the end of the 2010s. While the tax settings are tightening, the income side of the equation has never been stronger, and for many investors that has offset a good chunk of both the rate rises and the coming tax changes.

Third, the downturn is real but uneven. Our market tracking shows national prices fell 0.7 per cent in July, with Brisbane down 0.6 per cent — its second consecutive monthly fall — while Perth and Darwin are still edging up. In Brisbane, homes listed for sale have swung from 25 per cent below the five-year average in February to 6 per cent above it now. And on our numbers, if unemployment rises from its current 4.4 per cent, a correction of 10 to 15 per cent from the peak is on the table.

Fourth — and this is the part almost every headline misses — "the market" is not one thing. When Brisbane prints a 0.6 per cent monthly fall, that is an average of thousands of individual streets moving in opposite directions. Our research at Ripehouse Advisory is built at street and suburb level rather than city level, and the gap it exposes is confronting: in the same suburb, on the same council rates notice, the strongest and weakest streets routinely behave like two different investments.

That is what our R-Score does. We rank a location's fundamentals — supply versus demand, days on market, vacancy, stock on market, tenant demand depth, owner-occupier ratio and development activity — into a percentile score, then map it street by street as a heatmap. It is the difference between "Brisbane is falling" and "this pocket has three weeks of listings, 1 per cent vacancy and a 90-plus percentile R-Score, while the arterial-road strip four streets over has triple the days on market and half the tenant demand."

We see it constantly: within a single mid-ring suburb, our street heatmaps show one street in the top decile for tenant demand and days-on-market, while a street a few hundred metres away — same suburb, same school catchment, same median — sits in the bottom quartile, dragged down by flood overlay, unit-stock concentration and through-traffic. A buyer reading only the suburb median treats those as the same purchase. They aren't. Under the new rules, where the asset can no longer lean on a tax refund, that difference stops being a nicety and becomes the whole return.

So what should a Mark actually do?

  • If you're cash-flow positive after the rent rises: the case to panic-sell is weak. You're being paid to wait, and selling into a falling, high-stock market is how investors lock in the worst price. Get the street-level data on what you already own before you touch it.
  • If you're deeply negatively geared on an established property: model your numbers without the negative gearing offset. If the property only works because of the tax refund, it doesn't work. Then check whether the problem is the asset or the street — because one is fixable by repositioning, and the other isn't.
  • If you're looking to buy: the balance of power has shifted to buyers for the first time in years. This is the environment in which disciplined, data-led investors have historically done their best buying — while everyone else is reading headlines. Screen for high R-Score streets with tight vacancy, low days on market and genuine supply constraint, and the new rules stop being a threat and start being a filter that removes your competition.

What it means for you

The era of "buy anything, negative gear it, and let the tax office and the market do the rest" is over. The era of selective property investing — where the asset has to stand on its own cash flow and fundamentals — is just beginning. That is a better market for investors who do the work, not a worse one.

Here is the reframe Mark eventually landed on: tax settings change, rate cycles turn, and headlines are written about national averages nobody actually buys. What doesn't change is that a property on the right street — in a suburb with real supply constraint and real tenant demand — has outperformed the suburb average through every one of these shake-ups, while the wrong street has underperformed it through every boom.

The investors who come out ahead won't be the ones who sold fastest. They'll be the ones who repositioned smartest: right asset, right street, right data. Get those three right and the headline becomes background noise.
