Case study · THE ONE, Southbank
Level 38 · Sold October 2026A Singapore family was ready to pay cash for a A$1.85M river-view residence. Here is the structure that convinced them to keep over A$1 million of their capital free instead, and every number behind it.

The idea in one minute
01
The brief
Positive cash flow, no stress. The family planned to buy outright for their son, who is studying in Australia.
02
The question
Why lock up over A$2 million in one apartment, when a corporate tenant can pay for a loan on half of it?
03
The answer
Borrow 55%. The rent covers the running costs and the full mortgage repayment, and pays down the loan every month.
The residence
A 92 m² two-bedroom corner residence on the 38th floor of THE ONE at 1 Queens Bridge, Southbank, looking west over Crown, the Yarra and the CBD skyline. Corporate tenants pay a premium for this: two bedrooms with their own bathrooms, a ten-minute walk to the CBD, and a hotel tower address.

At these settings the tenant pays every running cost and the whole mortgage repayment, with A$430 a month to spare. Meanwhile the loan shrinks by about A$65,043 over five years.
The ownership engine
A corporate tenant pays A$2,500 a week. After the building, the council, the state and the manager are paid, what's left goes to the bank, and part of every repayment is your own loan getting smaller.

The honest trade-off
You could. A 50% loan leaves more cash each month. The rent, after costs, returns 4.45% of the price a year, and money borrowed at 6.50% costs more than that, so each extra dollar borrowed slightly reduces the monthly surplus.
The family chose 55% anyway, for liquidity: A$92,550 stays in their hands for other plans, and the rent still covers everything. It is a choice between two good objectives, not a right and a wrong answer.
Choose 50% when…
a bigger monthly safety margin matters more than keeping the last A$92,550 of capital free.
Choose 55% when…
capital for other opportunities comes first, and a modest monthly buffer is enough.

No surprises
Foreign buyers pay more to get in than locals do, and we show it upfront. The biggest item is Victoria's 8% foreign purchaser duty. Only A$185,100 (the 10% deposit) is needed at signing; the rest comes at completion, expected 2029–30.

Tax, explained simply
Two different sums matter. Cash flow is rent minus costs minus the full mortgage repayment. Taxable income is rent minus costs minus only the interest, minus depreciation on the new building and fittings. Repaying the loan itself is not deductible.
In this example the first year shows a tax loss of A$13,463. With no other Australian income, that loss is carried forward, not refunded, and the rent may attract no Australian income tax that year. We never add depreciation to the cash figures above.
What the family asked us
The family started with parent and son together, to keep options open. For this contract the solicitor confirmed the parent can be removed before settlement without a further FIRB fee or extra Victorian duty. Confirm this for your own contract.
Yes, but a trust needs its own FIRB application and adds cost. For most families it is simpler to decide names now and revisit estate planning closer to settlement.
Not automatically. His home is where he lives; this is an investment property with its own rent, expenses and depreciation. A mortgage-free first property can even help an Australian loan application later.
Both work. Equity from a Singapore property avoids the need for an Australian income at settlement. An Australian loan keeps the debt in the same currency as the rent, and its interest is usually deductible against that rent. How the money reaches the buyer (a gift or a properly documented loan) changes the tax result, so compare the after-tax cost closer to settlement.
No. Only the names on the contract and the 10% deposit are needed today. Finance is decided near completion, when rates and circumstances are known, and paying cash remains an option.
