If you’ve been putting off a property investment decision because of the negative gearing headlines from this year’s Federal Budget, it’s time to look at the actual numbers — not the noise.

Here’s the reform in plain English: from 1 July 2027, if you buy an established residential property, you can no longer use a rental loss to reduce the tax on your salary or wages. The loss can still be used, but only against rental income or a future capital gain. New builds keep the full, old-style negative gearing treatment. Anything you already own — or settle before Budget night, 12 May 2026 — is grandfathered under the old rules for as long as you hold it.

For a lot of investors, that reads like established property just lost its main selling point. It didn’t. It lost a tax perk that was always the smaller half of the story. The bigger half — long-term capital growth — was never touched.

Let’s prove it with a real scenario.

The scenario

This is a genuine holding-cost and 10-year projection for a $700,000 established investment property, the kind of asset that would fall under the new rules if purchased today.

• Purchase price: $700,000
• Rent: $630/week ($32,760 a year), a 4.7% gross yield
• Loan: 80% LVR, $560,000, interest-only at 6.54%
• Annual holding costs: interest, property management, council rates, insurance, water, land tax and a letting fee — $45,386 in year one against $32,760 of rent

Run those numbers and the property is roughly $12,600 out of pocket in its first year. That out-of-pocket gap is real — and it’s exactly the loss the old negative gearing rules let you offset against salary. Under the new rules, a buyer purchasing this same property after Budget night couldn’t use that loss against their wages anymore.

So what was that tax perk actually worth? And what did the investor get instead?

What the tax refund was worth

Tracking the property’s net annual cashflow, the loss narrows every year as rent grows and the fixed-rate interest cost stays flat. It goes from -$12,470 in year one down to just -$669 by year seven, then flips positive — $1,763 in year eight, $7,106 by year ten.

Add up the losses across those first seven years and you get a cumulative shortfall of $48,132. At a 37% marginal tax rate, that’s a lifetime tax refund of roughly $17,800 — spread across seven tax returns, a few thousand dollars a year at best.

That’s the number the headlines are worried about losing. It’s real money, and we’re not dismissing it. But it’s not the number that actually builds wealth.

What the property was worth

Over the same ten years, at a modest, unspectacular compounding growth rate, this $700,000 property becomes $1,377,006. That’s $677,006 of capital growth — on a property where the investor only ever put in an $140,000 deposit plus holding costs.

By year ten:

• Equity: $817,006 (loan balance never moved, thanks to interest-only lending)
• Total performance (cashflow + capital growth combined): $642,095
• Return on invested capital: 536.1%
• Cashflow: now firmly positive, adding income rather than costing it

Line the two numbers up and the comparison isn’t close. A $677,006 capital gain against an $17,800 tax refund. The growth in this property is worth roughly 38 times what the negative gearing refund was ever going to deliver. Even if you’re conservative about future growth rates, halve it, quarter it — you’re still looking at ten times the refund, easily, and usually a great deal more.

The tax refund was never the investment thesis

This is the point worth sitting with: negative gearing was always a cash-flow cushion, not a wealth strategy. It softened the early years while the asset did the actual work of compounding in value. Losing that cushion changes your first few years’ cash flow planning — it doesn’t change what a well-selected, well-located established property is capable of doing to your net worth over a decade.

Established properties still offer things new builds structurally can’t: proven locations, established infrastructure, land value that dominates the purchase price, and a track record of demand you can actually verify with sales data rather than a developer’s projection. None of that changed on Budget night.

What this means for you

If you’re weighing up an established property purchase, the right question isn’t “how much tax will I save?” It’s “where will this asset be in ten years, and can I comfortably fund the shortfall along the way?” The numbers above show a genuine, unglamorous, correctly-selected established property still turning an $140,000 deposit into a six-figure equity position and a five-hundred-percent-plus return on invested capital — tax refund or no tax refund.
