Buying vs Renting in Australia: A Reproducible Cost and Equity Comparison

Reviewed 1 October 2026. SettleAU editorial guidance using the linked primary sources. Examples are our own hypothetical scenarios, not market estimates. No independent legal, financial or education-professional review has been completed.

Make the decision practical before making it numerical

Start with how long you expect to stay, work and visa stability, access needs, school plans and a cash reserve after settlement. A purchase can limit your ability to move; renting can expose you to renewal and relocation risk. Neither a mortgage approval nor a rent-to-income ratio proves that a home fits your budget.

Compare homes that meet the same needs. A cheaper apartment and a larger house are different housing choices, not a clean rent-versus-buy experiment. Obtain property-specific quotes for rates, insurance, strata, repairs, conveyancing and finance. ASIC Moneysmart’s buying checklist.

The worked scenario and its limits

Rent and owner costs rise at each anniversary. Loan repayments stay constant. All figures are nominal AUD and retain full precision until display. General inflation is not separately applied to the wealth columns; the cost-growth assumptions above do that work. The renter makes each contribution at month-end. Negative differences would be withdrawals, so they must be affordable.

The example excludes grants, LMI, offset accounts, extra repayments, moving costs, renter contents insurance, land tax and tax on an eventual home sale; it assumes an eligible main residence for the buyer and a net investment return for the renter. A refundable rental bond and emergency reserve are not modelled. Add them for liquidity planning. Actual tax treatment and property costs require your own assessment.

How to reproduce the calculation

Let L be the $480,000 loan, i = 0.065 ÷ 12 and N = 360 monthly payments. The monthly payment M is L × i ÷ [1 − (1 + i)^−N] = $3,033.93. For a zero-interest loan, M = L ÷ N. Compare the loan repayment with Moneysmart’s mortgage calculator using the same inputs; lender day-count and payment rules may differ.

1. Start the loan balance B at $480,000 and renter portfolio I at $145,000.
2. Each month update B = B × (1 + i) − M. This distinguishes interest from repaid principal.
3. Use q = (1.04)^1/12 − 1. Update I = I × (1 + q) + M + that month’s owner costs − that month’s rent.
4. At year y, home value = $600,000 × 1.03^y. Buyer equity after sale = home value × 0.975 − remaining loan.
5. Compare equity with I at the same date. The initial deposit is already in buyer equity and the renter’s initial investment; do not add it again.

In month one, the buyer pays $3,033.93 mortgage plus $500 running costs; the renter pays $2,200 and invests the $1,333.93 difference. Principal repayment is a cash outflow but builds equity, so calling the whole mortgage an unrecoverable cost would be misleading.

Under these assumptions the ten-year difference is only $4,501.48 in the buyer’s favour. This is an arithmetic result, not a prediction or a general break-even period. A different purchase price, return, sale cost or time horizon can reverse it.

Change the assumptions before deciding

If the loan started at 8.5% instead of 6.5%, the payment on $480,000 over 30 years would be $3,690.78 a month, $656.86 more before other costs. This is a repayment stress test, not a recalculated wealth table. Also test a job interruption, major strata levy and selling earlier than planned.

Investment returns and property values can fall. A smooth annual growth assumption hides volatility, transaction timing and concentration risk. Decide whether you can sustain the cash flow before comparing possible long-term wealth.

Check each scheme separately

The expanded Australian Government 5% Deposit Scheme has no income caps and unlimited places. First-home eligibility includes citizenship or permanent residency, age, prior ownership, owner-occupation, location price caps and participating-lender criteria. A government guarantee is not a cash grant and does not remove the borrower’s repayment obligation.

The Help to Buy scheme is different: it uses shared equity and requires Australian citizenship, alongside its own income, property and other conditions. Do not assume every scheme accepts permanent residents or can be combined.

State grants and transfer-duty concessions depend on the contract date, property type/value, ownership history, residence and sometimes the co-buyer’s status. Use the official state and territory grant selector and the relevant revenue office for a written calculation. This page does not reuse a national table of approximate duty savings.

Verify authority to buy before making an offer

Foreign-person status for property rules is separate from a lender’s willingness to lend and from grant eligibility. From 1 April 2025 to 31 March 2027, foreign persons, including temporary residents, are generally prohibited from buying established dwellings, subject to limited exceptions. Current foreign-investment rules. Check the exact buyer, co-buyer and property before signing; a conditionally approved loan is not foreign-investment approval.

• Ask a conveyancer or solicitor to review title, contract, disclosure, cooling-off and auction conditions before you commit.
• Get the lender’s actual rate, fees, loan term and assessment, and confirm the size of the cash reserve after all settlement costs.
• Ask the revenue office about grants and duty separately; model unapproved assistance as zero.
• For a unit, review strata records, planned works and special levies. Obtain inspections suitable for the property.
• Keep a rental alternative using the same housing needs and horizon so an urgent offer does not replace the comparison.

Questions and answers

Does buying always win after seven to ten years?

No. The result changes with price growth, rent, interest, investment returns, fees and time in the home. The worked example is one explicit scenario.

Why does the renter invest the deposit?

It accounts for the opportunity cost of money used to buy. Comparing buyer equity with a renter who is assumed to save nothing would answer a different question.

Are permanent residents eligible for every first-home program?

No. Each program has its own rules. The 5% Deposit Scheme includes eligible permanent residents; Help to Buy requires citizenship.
