The Borrower
A married couple with no dependants: a maintenance technician with more than 10 years at his employer on a base income of $165,454, and a solicitor on $105,000. Their home, valued at $1,300,000, has been owned since February 2021.
Both are high income earners who watch their discretionary spending closely.
The Goal
- Refinance their existing lending to a sharper rate
- Release equity to cover the deposit and costs on a new investment purchase
- Hold a fully assessed pre-approval before placing any offers
- Keep an offset facility and the freedom to make extra repayments without penalty
The Problem
None of the interest on their home loan was deductible. They held $465,000 in offset, enough to clear most of the $525,000 balance, and they also needed a deposit and costs for a $1,400,000 investment property.
Using the cash directly as the deposit would have left the non-deductible home loan where it was. Paying the home loan down first, then borrowing the deposit back against the home as a separate investment split, turns the same dollars into deductible debt.
| Item | Value | Purpose |
|---|
| Home | $1.3m | Non-deductible |
| Investment property | $1.4m | To be purchased |
| Offset savings | $465k | Held against the $525k home loan |
What We Did
- The couple used $465,000 of offset savings to pay the home loan down from $525,000 to $60,000 ahead of settlement.
- We refinanced the remaining $60,000 at 5.34% as its own owner-occupied split.
- $390,000 of equity was released against the home as a separate investment split at 5.44%, covering all the funds needed to complete the purchase.
- A $1,120,000 pre-approval at 5.54% was secured for the purchase: 80% of a $1,400,000 price.
- All lending stayed on principal and interest, so the last $60,000 of home debt clears first and the investment debt is paid down after that.
- Servicing used base incomes only, leaving out a higher duties allowance and bonus, with estimated rent of $1,000 a week.
- Everything sits on a standard variable package with an offset facility.
- With the pre-approval in hand, they bought in Brisbane through a buyers agent we work closely with and rented the property straight away.

The Tax Outcome

Budget note. The 2026-27 Federal Budget changed the rules for established investment property bought after 12 May 2026: from 1 July 2027, net rental losses on those properties can no longer be offset against salary. The same pay-down and re-borrow structure continues to apply to share and ETF investing. See debt recycling vs negative gearing.
Key Takeaways
- Cash used directly as a deposit leaves your home loan non-deductible. Routing it through the home loan first changes the tax character of the same dollars.
- A fully assessed pre-approval before making offers removes finance risk from the purchase.
- Keeping investment debt on principal and interest is a choice. It suits borrowers who want all debt reduced quickly.
