Brisbane — the arithmetic, with its assumptions on the table
| Plan | Price | Target Rent | Return on build cost | Cash-on-Cash |
|---|---|---|---|---|
| 30 m² Compact Studio | $130,000 + GST | $360 / wk (target) | 13.1% of GST-inclusive build cost, before costs | Not published — depends on your rate and actual rent |
| 60 m² Two-Bedroom | $178,000 + GST | $470 / wk (target) | 12.5% of GST-inclusive build cost, before costs | Not published — depends on your rate and actual rent |
| 80 m² | $210,000 + GST | Rental estimate to follow | — | Available November 2026 |
These are arithmetic illustrations, not returns we have achieved or expect you to achieve: annual rent at the target weekly figure, divided by the GST-inclusive build cost. They exclude vacancy, council rates, insurance, management fees, maintenance, the land the dwelling sits on, any interest on borrowed funds, and tax — so a real net figure is materially lower and can be negative. They are not a property rental yield, because the denominator is the build cost rather than the value of the land and house. Target rents are our own leasing estimate for these suburbs and are not a forecast of what your dwelling will let for. Queensland build prices apply; if your site is within Brisbane City Council, add the council infrastructure charge (~$8k–$12k) to the cash you fund yourself. We removed the previously published "cash-on-cash" percentages from this table on 31 August 2026 because they were computed before finance costs, which made them wrong rather than merely optimistic.
