Whenever tax policy changes, the housing market tends to get analysed in the most dramatic way possible. Over the last few days I’ve seen plenty of commentary suggesting the proposed negative gearing and CGT changes will crash property prices, destroy investor demand, or permanently suppress the market altogether.

Maybe there is some short-term price weakness. But I think a lot of the commentary is blending completely different parts of the system together.

So let’s slow down and think it through from first principles.

What Actually Changes?

If investors can no longer offset losses from established property against wage income immediately, borrowing capacity falls. That part is real.

The investor still receives the tax benefit eventually, but the timing changes. Instead of reducing PAYG tax obligations immediately, the losses become trapped inside the property and carried forward to offset future rental profits or future capital gains later in the holding cycle.

Mechanically, that changes cash flow, and because banks assess serviceability based on cash flow, it also changes borrowing capacity.

At the moment, investors make up roughly 27–30% of housing lending. If borrowing capacity for that segment falls by 20–25%, then the first-order effect is probably not a 25% collapse in housing demand. Mechanically, it’s more likely something closer to a 6–8% reduction in aggregate purchasing power.

That matters. It’s not insignificant. But it’s also very different to saying the housing market itself collapses.

Those are two completely different layers of analysis.

Markets Are Human Systems

The second layer is behavioural.

Housing markets rarely respond cleanly or rationally to structural change. Fear, uncertainty and headlines usually overshoot before the system gradually recalibrates. Buyers hesitate, sellers become nervous, and transaction volumes slow while everyone waits for clarity.

That means the short-term market reaction can easily become larger than the underlying mechanical effect itself.

So yes, I think it is entirely plausible that some parts of the market experience softer prices, weaker sentiment and lower transaction volumes over the next 12–24 months. But this is where the analysis usually starts breaking down because a reduction in borrowing capacity is not the same thing as a disappearance of housing demand.

People still need somewhere to live. Population growth hasn’t disappeared, rental demand hasn’t disappeared, and the dwelling shortage itself hasn’t suddenly been solved simply because tax settings changed.

In fact, there’s a reasonable argument that parts of the supply side may tighten further.

The Supply Side Hasn’t Improved

Australia still has a structural housing undersupply, limited construction capacity, elevated construction costs, labour shortages and persistent rental shortages across most capital cities. None of those variables disappear because tax settings change.

If anything, the proposed structure may create a growing disincentive for existing investors to sell established property because deferred losses become increasingly valuable later in the holding cycle. That potentially reduces the amount of stock available to transact.

At the same time, the policy appears designed to redirect investor demand toward new property. The problem is that Australia already struggles to physically deliver enough housing supply under the current system.

So we potentially end up in a strange situation where policy successfully stimulates demand for new housing while the industry simultaneously struggles to produce enough of it.

That distinction matters because prices are not determined by demand in isolation. They are determined by demand relative to deliverable supply.

Capital Doesn’t Disappear. It Rotates.

This is the part I think many people are missing.

The more I think through these changes mechanically, the less I think the outcome is simply “less property investment.” What seems far more likely is capital rotation.

This is the same pattern you see across almost every other investment market. In equities, capital often starts in blue chips, then gradually moves into large caps, mid caps, small caps, emerging markets and eventually frontier markets as investors move further out along the risk curve searching for stronger returns.

The further out you move, the more volatility you generally accept, but the return potential often rises as well.

Property markets behave in much the same way.

During periods of abundant liquidity, investors can afford to prioritise blue-chip locations, lower yields and long-duration growth stories because cheap debt and favourable tax treatment help them survive the holding costs.

But once liquidity tightens, the market starts caring about very different things. Yield matters more, entry price matters more, cash flow matters more, and holding efficiency suddenly becomes critical in a way it wasn’t during the high-liquidity phase of the cycle.

That naturally pushes capital toward the parts of the market where the structure still works efficiently.

Where Demand Likely Flows Next

This is why I don’t think the proposed changes eliminate investor demand. They change where that demand can realistically transact.

Investor capital is likely to rotate towards: cheaper markets, higher-yielding assets, outer-ring growth corridors, secondary cities and new property where the policy incentives still support the holding structure.

At the same time, expensive low-yield established suburbs may become harder for leveraged investors to justify. Not necessarily because they are bad assets, but because the holding structure becomes materially harder to absorb without immediate tax relief.

This is where I think the opportunity layer starts emerging.

The market is probably moving from a broad beta environment, where almost everything rises together, into a much more selective environment where: asset selection, market positioning, yield profile, and affordability dynamics become increasingly important drivers.

That usually creates more dispersion between average outcomes and exceptional outcomes. Historically, the investors who tend to perform best during these phases are not necessarily the ones waiting for complete certainty. They’re usually the ones identifying where capital is likely to rotate before the broader market fully reprices.

That’s why I think this period may ultimately create more opportunity than many people currently realise.

The Bigger Shift Happening Underneath

If the policy reduces borrowing capacity but doesn’t materially improve housing supply, then the long-term housing problem itself still exists. The market simply has to find a new clearing point.

That clearing point may involve:

• softer prices in some markets,
• higher rents in others,
• and stronger capital flows into locations where affordability and yield still make sense.

Over the long run, land still tends to absorb inflation and monetary expansion. Affordability constraints don’t eliminate growth; they change the shape of growth. That’s why we continue seeing the same structural patterns emerge globally: smaller lot sizes, higher density housing, unitisation of land, and stronger relative performance in affordable submarkets compared to premium detached housing.

The market adapts mechanically to affordability ceilings.

This is also why I think the next phase of the property cycle becomes far more fragmented. The post-COVID period was unusually forgiving because massive liquidity created a high-beta environment where broad market exposure alone often looked like skill.

That phase is fading.

From here, outcomes are increasingly likely to diverge. The national market may slow while specific submarkets continue to perform extremely well. This is not unusual and it is the normal state as cycles mature.

In short, this isn’t the end of opportunity in property. It is the end of easy, broad-based gains. From here, outcomes will be driven by positioning. Where you buy, how you structure, and how early you adapt will matter more than ever.

Periods like this tend to favour investors who move before the market fully adjusts. By the time certainty returns, the opportunity is rarely where it once was.
