Only 14% of median-income households in Australia can afford the median-priced home, down from 43% just three years ago. That single figure explains why the renting vs. buying debate has shifted from a lifestyle choice to a financial survival question for most people. Mortgage rates above 6.5%, rents climbing roughly 7% annually, and near-record property prices mean neither option feels cheap.

The numbers look different depending on which city you’re in, how long you plan to stay, and what you think property prices will do next. What works in Perth doesn’t work in Sydney. What makes sense over ten years can be a disaster over three. Here’s what you actually need to know.
The central concept here is break-even period — the number of years it takes for the costs of buying to be offset by the equity you build. If you sell before that point, you’d have been better off renting and investing the difference.
What I tend to notice is that most people compare the monthly mortgage payment to their rent and stop there. That misses half the picture. The loan term and interest rate you lock in dramatically shift the numbers, and so do the costs nobody talks about at the open home.
What buying actually costs each month — city by city
The headline mortgage payment is only the start. Council rates, water charges, building insurance, and maintenance add hundreds of dollars per month. In Brisbane, insurance alone can run $400 to $800 per month for properties in flood or storm-prone areas.

| City | Median house price | Monthly buying cost | Monthly rent | Monthly gap |
|---|---|---|---|---|
| Sydney | $1,190,000 | $8,031 | $3,120 | $4,861 |
| Melbourne | $830,000 | $5,697 | $2,515 | $3,182 |
| Brisbane | $890,000 | $6,140 | $2,780 | $3,360 |
| Perth | $810,000 | $5,565 | $2,862 | $2,703 |
| Adelaide | $790,000 | — | $2,427 | — |
That monthly gap is cash you never see again. But the buyer is also repaying principal. In Sydney, the first year of mortgage payments repays roughly $16,800 of the loan balance. The renter pays $38,040 in rent and owns nothing. The question is whether the equity gain outweighs the extra cash you had to spend to get it.
The deposit itself carries an opportunity cost that most buyers ignore. A 20% deposit on the national median dwelling of $985,000 is about $184,568. If that money sat in a diversified investment earning 7% annually, it would grow to roughly $258,600 in five years and $363,000 in ten. That’s money you trade for the chance to own a home.
Where the renting vs. buying argument goes wrong
Comparing the mortgage to the rent and stopping there
The monthly mortgage on a Sydney house is about $6,504. Rent is $3,120. That $3,384 difference looks like a clear win for renting. But the buyer also repays about $16,800 in principal in year one and, if prices rise 6%, gains roughly $71,400 in equity. The renter’s $38,040 in rent buys nothing. The full picture includes both the cash outflow and the asset gain.
Assuming past growth will repeat
Perth grew 16.8% in the past year. At that rate, buying crushes renting. But if growth drops to 2%, the break-even period stretches past 15 years. The Realestatecalc analysis shows that at 2% annual growth, renting and investing the difference wins over 10 to 15 years. At 6% growth, buying wins after five to seven. Nobody knows which rate the next decade will deliver.
Ignoring the cost of selling
Selling a property costs 1.5% to 2.5% in agent commission plus $3,000 to $10,000 in marketing. On a $1 million house, that’s $18,000 to $35,000. If you sell within five years, those transaction costs can wipe out any equity gain. This is why buying only makes financial sense if you stay put for at least seven years in most markets.
Overlooking the landlord’s leverage in a 1.1% vacancy market
With vacancy rates at 1.1% nationally, landlords hold almost all the cards. Rents in Brisbane rose 9.4% in the past year. A tenant who budgets for 5% annual increases can find themselves priced out of a suburb after two years. Renting offers flexibility, but that flexibility comes with no cap on how much your housing costs can rise.
How to decide which path fits your situation
Work out your time horizon first
If you expect to move within five years, renting almost always wins. The transaction costs of buying and selling — stamp duty, agent fees, legal costs — eat up any equity you might build. If you plan to stay seven years or longer, buying starts to pull ahead in most cities, especially if property growth runs above 4% annually. The Lion Brief analysis puts Sydney’s break-even at 22 years, meaning even a decade-long stay might not be enough there.
Run the numbers for your specific city
Adelaide has the shortest break-even period at roughly 7.1% required annual growth. Perth’s 16.8% growth in the past year made buyers there look like geniuses, but that pace is unlikely to continue. Melbourne needs about 7% annual growth to break even in 12 years. Brisbane sits somewhere in between, with long-term tailwinds from Olympic infrastructure spending. A one-size-fits-all answer doesn’t exist.
Factor in the hidden costs of each option
Buyers need to budget for stamp duty ($15,000 to $52,000+), council rates ($2,000 to $3,000 per year), building insurance ($1,500 to $7,500 depending on location), and maintenance (roughly 1% of property value annually). Renters need contents insurance (about $600 per year) and should expect annual rent increases of 5% to 9% in tight markets. Neither side escapes ongoing costs.
Consider the emerging regulatory landscape
Several states are reviewing tenancy laws, rent caps, and first-home buyer schemes. Queensland has expanded its first-home buyer stamp duty concession. NSW offers full exemptions up to $800,000. These policies shift the math, especially for first-home buyers. Keep an eye on changes in your state — a new grant or concession can turn a borderline decision into a clear winner.

The one number that changes everything
The break-even period is the single most useful figure in this entire debate, and most people never calculate it. In Sydney, you need 22 years of ownership just to come out ahead of renting and investing the difference. In Adelaide, it’s closer to seven. That gap isn’t about lifestyle — it’s about whether the maths works in your specific market. If you’re unsure about the legal side of a property decision, speaking with a professional who understands real estate law can help clarify your options before you commit.
