Refinancing an Investment Property vs Your Home Loan:

Mechanically, refinancing an investment loan involves the same steps as refinancing your home: a new lender assesses your application, discharges the old loan, and registers the new one.

What changes is what's riding on getting the structure right.

On an owner-occupied loan, the main goal is usually minimising interest and paying it down faster. On an investment loan, interest deductibility and loan purpose become just as important as the rate itself.

Interest on an investment loan is generally tax-deductible because the debt relates to earning rental income — but that deductibility follows the purpose of the borrowing, not just which property secures it.

If you refinance and pull out equity to fund something unrelated to the investment (a car, a holiday, renovations on your own home), that portion of the new loan is very likely not deductible, even though it's secured against the investment property.

This is why investment refinances are usually split into clearly defined loan accounts — one for the original deductible debt, and a separate split for any new borrowing, so the purpose of each dollar is traceable if the ATO ever asks.

The May 2026 Federal Budget introduced negative gearing ring-fencing for established investment properties purchased after 12 May 2026, alongside a 30% minimum tax rate on capital gains, replacing the previous 50% CGT discount.

New builds and SMSF-held properties have specific exemptions.

These changes affect the ongoing tax treatment of the investment — not the refinancing process itself — but they matter when weighing whether to hold, refinance and expand, or restructure.

If your investment property was purchased before this date, it's worth confirming which rules actually apply to you before assuming the new settings affect your loan strategy.

Investment refinancing is where good structure earns its keep — properly split loans, clean purpose documentation, and a strategy that accounts for the current tax settings. A review can show you exactly where your current structure stands.
