What this shows
Property value (grey bars, left axis) is the projected market value each year using your capital-growth assumption. The capital profit if sold line (coral, left axis) is the money you'd actually walk away with that year after repaying the loan, paying selling costs, paying CGT, and getting back the cash you put in. The rent collected line (teal, right axis) is gross annual rent received, grown at your rent-growth assumption.
What this shows
Three views of how the position evolves year by year. Property value (dashed) shows the asset growing at your capital-growth rate. Equity (coral) is value minus loan balance — how much of the property you actually own. Cumulative cash flow (teal) is the running total of all after-tax rent (positive) or top-ups (negative) you've put in since day one.
What this shows
The yearly cash position after every cost and tax effect. Green bars = positive years (the property paid you). Red bars = years you had to top it up from your pocket. This is the most honest picture of what holding the property feels like on a year-to-year basis.
What this shows
Where every dollar of the projected sale price goes. Net to you is what lands in your bank account; the rest is consumed by loan payout, selling costs and capital gains tax. The CGT slice depends on which regime applies (50% discount, indexation + 30% min tax, or a split of the two).

What this shows
How fragile your outcome is to the capital-growth assumption — the single biggest swing factor in any property forecast. Each point on the line re-runs the entire model at a different growth rate. Where the line crosses the dashed zero, that's roughly the growth rate needed just to break even over your hold period.

What this shows
The same upfront cash invested four different ways, held the same number of years. The property includes all rent, costs, tax and the final sale (after CGT and loan payout). The ASX 200 ETF compounds at its assumed total return; the gold line compounds at gold's long-run average; the inflation line is what you need to just preserve your purchasing power. Any year the property bleeds cash, that shortfall is invested in the comparison asset too (so they get the same total dollars over the life of the deal). Gains on the comparison assets are taxed under the same 2026-Budget CGT regime that applies to shares and ETFs — the transitional split (50% discount on the pre-1 Jul 2027 portion, then cost-base indexation + 30% minimum tax on the post-1 Jul 2027 portion), since non-property assets are never grandfathered.
What this shows
The full year-by-year ledger. Cash flow is pre-tax (rent minus all cash costs); tax effect is the value of any deduction or the tax bill on net profit; after-tax is the actual dollars in or out of your account that year. Cumulative is the running total.

About this model

Reflects the 2026 Federal Budget proposals (announced 12 May 2026): from 1 July 2027, negative gearing on established residential property bought after 7:30pm 12 May 2026 can only offset rental income / residential property gains (excess losses carry forward), and the 50% CGT discount is replaced by cost-base indexation plus a 30% minimum tax on the real gain accruing after 1 July 2027. The CGT change applies to all CGT assets (shares, ETFs, gold, crypto), not just property, so the comparison assets are taxed on the same basis. New builds retain full negative gearing and the choice of the 50% discount. Properties contracted on/before 12 May 2026 are grandfathered. The main residence, superannuation funds and widely-held trusts are exempt. These are proposed rules that may change in legislation. Resident tax rates 2025–26 are used (incl. 2% Medicare levy). This is general information, not financial, tax or legal advice — consult a licensed adviser before acting.

How these figures are calculated

Stamp Duty (Transfer Duty): Calculated using each state's 2024–25 residential transfer duty brackets for owner-occupiers. First home buyer concessions and investor surcharges are applied where selected.

Lenders Mortgage Insurance (LMI): Estimated at approximately 1.5–2.5% of the loan amount, assuming an 85% LVR. Actual LMI depends on your lender, LVR and loan size.

Conveyancing / Legal Fees: Typical range of $1,500–$3,000 covering contract review, searches and settlement. We use a mid-range estimate.

Building & Pest Inspection: Typically $400–$800 combined for a standard residential property.

Loan Application & Mortgage Registration: Includes bank application fees ($300–$600), mortgage registration (state-based, usually $150–$230) and transfer registration fees.

Council & Water Rate Adjustments: Estimated at around 0.1% of the purchase price — the buyer typically reimburses the seller for pre-paid rates.

These estimates are indicative only. Always confirm exact figures with your conveyancer, broker and the relevant state revenue office before committing to a purchase.

Refinance costs vary by lender and state (typically including a discharge fee, application fee, and government mortgage registration fees).
