New-build investors set to gain under CGT changes

By mid-2027, Australian property investors will face a pivotal decision: maintain their current portfolios under evolving tax settings or reallocate capital toward new-build properties to preserve access to the 50 per cent capital gains tax discount.

This choice, created by the 2026/27 Federal Budget’s differentiated treatment of existing versus new-build dwellings, could fundamentally alter demand patterns across the residential market.

What property investment rules have changed?

The budget reforms modify tax treatment for residential property investment in two key areas.

For investments in existing properties made after the budget date, negative gearing provisions will be removed from July 2027, and capital gains will be taxed under an inflation-indexed system. Newly constructed dwellings, however, are carved out from these changes entirely.

Under the new-build exemption, investors purchasing newly constructed properties retain access to negative gearing provisions, the existing 50 per cent CGT discount framework, and grandfathering arrangements that protect capital gains accumulated on existing investments up to July 2027.

This differentiated approach was designed to incentivise new housing supply while gradually transitioning the treatment of established stock.

For investors, it creates distinct pathways depending on property type and purchase timing. For developers, it signals a potential redirection of investment capital.

What’s the decision for investors?

Not all investors will respond identically.

Some, particularly those holding properties in highly desirable locations with strong capital growth prospects, may maintain existing portfolios despite modified tax treatment. Others may see portfolio optimisation opportunities in transitioning toward new-build stock while preserving favourable tax settings.

As some investors pause acquisition activity in the existing property market while evaluating strategies, demand pressures on established stock may moderate, potentially tempering price growth.

Conversely, if meaningful investor capital redirects toward new builds, demand for this product category could intensify.

Given existing supply constraints in new residential construction, concentrated demand for limited new-build stock could create upward price pressure, particularly for apartments where yields typically exceed detached housing.

This suggests potential first-mover advantages for investors who secure off-the-plan commitments early, and for developers who position projects to capture this emerging buyer segment.

Projects already under construction and those nearing completion could see investor interest intensify in the near-term.

How big is this opportunity?

Historical lending data provides perspective on potential demand shifts.

Over the past five years, new investor loans averaged approximately 181,000 annually across Australia.

Of these, roughly 149,000 were for existing dwellings, with around 32,000 for new builds or new construction.

If even one-third of the investor demand historically directed toward existing properties were to pivot toward new builds, this would represent an additional 50,000 annual transactions seeking newly constructed dwellings, more than doubling recent new-build investor activity.

This scale of demand redirection, should it materialise, would represent a substantial opportunity for developers capable of delivering appropriate product.

How could developers respond?

Apartment developments appear well-positioned to benefit from potential demand shifts.

Many investor buyers, particularly first-time investors and rentvesters, are drawn to apartments due to lower entry price points, established rental demand, and often attractive amenity packages.

Designing product with investor requirements in mind, such as efficient floor plans, strong yield characteristics, and low-maintenance specifications, may enhance appeal.

Many investors favour off-the-plan purchases, which allow them to secure properties before completion and potentially benefit from capital appreciation during construction.

Developers with a strategy to optimise off-the-plan sales may be well positioned to capture early-stage demand as investors begin repositioning portfolios ahead of July 2027, and to leverage increased demand for new-builds over the following years as negative gearing benefits reduce for existing investments.

Increased investor demand and associated price support for new product could improve feasibility for projects that have stalled due to construction cost pressures.

While this doesn’t eliminate challenges, stronger anticipated demand may shift feasibility thresholds for some developments, potentially unlocking supply in constrained markets.

What comes after the Federal Budget?

New data released by Cotality on Thursday (21 May) showed that the sky has not immediately fallen in for investors.

Total loan commitments fell 6.2 per cent in the March quarter due to RBA hikes and low confidence. Owner-occupiers pulled back faster than investors, pushing the investor share of loan volumes to a record 41.0 per cent.

But these policy changes still represent a significant recalibration of Australia’s residential property investment framework.

Their ultimate impact depends on how investors, developers and the broader market respond in practice.

Not all investors will pivot toward new builds, and supply-side realities will influence how quickly demand patterns shift.

What seems clear is that differentiated treatment creates distinct investment pathways with different risk-return profiles and tax characteristics.

For investors, this necessitates fresh portfolio evaluation.

For developers, it presents opportunities to design product and sales strategies targeting an investor segment with strengthened incentives to purchase new construction.

Those who understand the dynamics early and position strategically may find themselves well-placed in a reshaped residential investment landscape.
