Property Tax Overhaul Pushes Millennial to Sell, Not Hold

Why the Maths Has Changed for Buy-and-Hold Investors

The mechanics here matter. Negative gearing has long worked by allowing an investor to offset a rental loss against other taxable income, effectively subsidising the holding cost of an underperforming asset while betting on long-term capital growth. When the tax treatment of that loss becomes less generous, or when the surrounding cost environment makes the loss itself larger, the entire calculation can flip from a defensible long-term strategy into a losing one in present-value terms.

In broad terms, a tax overhaul does not need to strip away an investor's equity to influence behaviour; it simply needs to weaken the after-tax return on holding enough that selling and reinvesting elsewhere starts to look like the more sensible option.

This dynamic compounds with what is happening on the borrower side of the market. realestate.com.au separately reports that loan demand from first home buyers has dropped for a third straight month, a signal that affordability and financing pressure are hitting both ends of the market simultaneously. Fewer first home buyers queuing up to purchase means less competitive tension underneath existing investor stock, which in turn makes the decision to sell now, rather than wait, more attractive for investors reassessing their tax position.

Investors should treat this as a prompt to run their own numbers rather than assume historical strategies still apply. A property bought a decade ago under one tax regime may no longer deliver the same after-tax outcome under a revised one, even if the underlying asset has performed exactly as expected on a pre-tax basis.

Background: How Negative Gearing and CGT Interact

Negative gearing and capital gains tax treatment have always worked together as a package deal for Australian property investors — tolerate the annual loss, claim the deduction, then crystallise the gain later at a discounted CGT rate. When either half of that package shifts, the whole strategy needs re-pricing. For a full breakdown of how these settings interact with depreciation and cost base adjustments, see our Australian Property Tax Guide, and for guidance on how renovation spend is treated for tax purposes before a sale, see our guide on Renovation for Profit — How to Add Value to Australian Investment Property.

Depreciation schedules also play into this decision. An investor approaching the point where their building's depreciable value is largely exhausted has less annual deduction to offset against rental income, making the negative gearing position less attractive on a standalone basis regardless of broader tax changes. For investors weighing whether to sell or hold, understanding where they sit on that depreciation curve, detailed in our Property Depreciation Schedules guide, is a necessary input into the decision.

What This Means for Investors and Owner-Occupiers

For current investors, the lesson from this case is to recalculate the after-tax holding cost of every property in the portfolio under the current tax settings, not the settings that applied when the property was purchased. A loss-making property that made sense under one regime may no longer clear the hurdle rate once the tax overhaul changes the deduction available or the effective CGT outcome on eventual sale. Running that number now, rather than waiting for a forced sale later, preserves optionality.

For first home buyers, the combination of investor exits and falling loan demand, as flagged in the third-straight-month decline reported by realestate.com.au, could eventually translate into more stock coming to market with less competition from owner-occupiers who have also pulled back. That is a double-edged signal: more choice, but also a market where financing capacity is visibly shrinking across the board. Borrowers should treat current conditions as a reminder to stress-test their own serviceability rather than assume today's settings will hold indefinitely.

For investors specifically weighing an exit, the practical step is to model the net proceeds after CGT, agent fees, and any depreciation clawback, then compare that figure against the expected after-tax return of continuing to hold under the new tax settings. Where the sale proceeds, reinvested elsewhere, clear a higher after-tax return than continuing to hold the existing asset, the decision to sell — as this millennial investor has done — becomes a rational wealth-building move rather than a retreat from property altogether.

The broader signal from this case is that Australian property investors can no longer assume a tax strategy that worked five years ago still works today. Anyone holding a negatively geared property should revisit the after-tax maths under current settings before deciding whether to sell, hold, or restructure, because the goalposts, as this case shows, have genuinely moved.
