In Sydney, mortgage repayments on a median house are 106% higher than the rent on the same property. In Brisbane, 75% higher. Melbourne and Adelaide, 66% and 63%. New analysis from Compare the Market puts numbers on what many Australians already know. Renting is not always a choice. For a growing share of the population it is the only option the monthly numbers make possible.

Compare the Market analysed median house and unit values alongside median rents across Australia's capital cities, assuming a 20% deposit and a 6% interest rate. The analysis excluded stamp duty, council rates, insurance, maintenance, and the opportunity cost of tying up a large deposit, meaning the real gap between buying and renting is likely even wider than the figures suggest.
Sydney is the most extreme example. Based on a median house price of just over $1.6 million, monthly mortgage repayments are estimated at approximately $7,708. The median monthly house rent is approximately $3,735. That is a gap of almost $4,000 per month, before a single additional ownership cost is factored in.
Brisbane has the second largest gap despite its reputation as a more affordable alternative to Sydney. Rapid price growth has transformed the Queensland capital into one of Australia's most expensive housing markets. Monthly mortgage repayments on a median house are estimated at $5,640 against median rent of $3,228, a gap of approximately $2,400 per month on a required deposit of more than $235,000.
Melbourne and Adelaide recorded gaps of 66% and 63% respectively. Canberra came in at 55%. Perth at 48%. Hobart at 37%.
Darwin was the exception. Mortgage repayments on a median-priced house were only approximately 5% higher than the median rent, reflecting lower property prices and high rental costs relative to values.
The comparison becomes far less extreme for units, which is one of the reasons apartments remain an important entry point into home ownership.
In Sydney, estimated repayments on a median-priced unit were approximately 30% higher than rent, compared to 106% for houses. Melbourne's unit gap was 17%. Perth's was 15%. Canberra's was 10%.
Darwin again stood apart. Compare the Market estimates monthly mortgage repayments on a median unit at approximately $2,125 against median rent of roughly $2,648, making buying a unit in Darwin cheaper on a monthly basis than renting one.
Brisbane remained the least affordable unit market for buyers relative to renters, with repayments approximately 43% higher than monthly rent despite strong population growth and tight vacancy rates.
The monthly gap between renting and buying an owner-occupied home is real. For many Australian households it is the number that makes home ownership in their preferred city impossible right now, not undesirable.
That does not mean property is out of reach. It means the traditional path of buying where you live is not the only path worth considering.
The deposit required for a median house ranges from approximately $142,000 in Darwin to more than $321,000 in Sydney. Those are large numbers. They are significantly more accessible when directed toward an investment property in a market where entry points are lower, yields are stronger, and the long-term growth case is compelling.
The question for most Australians isn’t whether buying is better long-term. It almost certainly is. The question is which property to own first and where. For many households the answer is not the family home in an expensive capital city. It is an investment property in a market where the entry point is accessible, the yield supports the cash flow, and the growth fundamentals are in place.
When the monthly cost of buying a median house in Sydney is 106% higher than renting one, a growing proportion of the population has no realistic path to ownership regardless of their financial discipline or ambition. Renting is not a preference for most of these households. It is the only outcome the numbers allow.
That structural dynamic is the foundation of Australia's rental demand story. It is not driven solely by migration or population growth. It is driven by the widening gap between what properties cost to buy and what households can realistically afford to service at current interest rates.
Add the 2026 budget changes reducing investor activity and therefore rental supply, the housing construction shortfall of 196,000 completions against demand for more than 250,000 according to the Housing Industry Association, and vacancy rates sitting at or near record lows in every capital city, and the demand side of the rental equation looks structurally stronger than at any point in recent history.
For investors with quality assets in well-located rental markets, the combination of rising rents and a permanently large pool of tenants who cannot afford to buy is not a short-term condition. It is a structural feature of the Australian housing market that is deepening rather than resolving.
Rentvesting is how a growing number of Australians are solving this problem.
Rentvesting means renting in the suburb or city where you choose to live while owning an investment property in a market where the numbers stack up. You capture the wealth-building benefit of property ownership, the equity growth and compounding returns, without being tied to a mortgage in a market where repayments are double the rent.
It is not giving up on home ownership. It is sequencing it more intelligently. Build the asset base first through investment property in accessible markets. Use the equity to eventually buy the home you want rather than the home the bank will let you have right now.
The data above reinforces exactly why this approach makes sense in 2026. In a city where buying costs 106% more than renting, the opportunity cost of directing every dollar toward an owner-occupied mortgage rather than an investment portfolio can be enormous.
