Rental Pressures Contiune and Tight Housing Supply
The September 2025 Cotality Housing Value Index highlights ongoing challenges and opportunities in Australia’s rental market. For landlords, conditions remain shaped by strong demand, low vacancy rates and modest growth in dwelling values, with dynamics differing across the capital cities and regional areas.
Nationally, dwelling values lifted slightly over the 30 days to 31 August, with capital cities generally outperforming regional markets. For landlords, this has two implications. First, the underlying value of investment properties continues to trend higher in most urban centres, reinforcing long-term capital growth. Second, rental demand is persisting at elevated levels due to population growth, migration inflows and constrained housing supply.
Vacancy rates remain critically low in every capital city. Brisbane, Adelaide and Perth are particularly tight, with tenants competing for limited stock. This is driving rental increases, though the rate of growth has moderated compared with the peaks of 2023 and 2024. For landlords, this environment has sustained gross rental yields, with returns improving slightly as rental income has risen faster than dwelling values in several markets.
The report shows that Brisbane and Perth stand out for landlords, where yields have lifted due to rapid rental growth and ongoing affordability relative to Sydney and Melbourne. Adelaide, too, continues to perform solidly. Sydney and Melbourne present a more complex picture. While demand is strong, stretched affordability is constraining how much tenants can reasonably pay, placing a natural cap on rent increases. Hobart and Darwin remain subdued, with weaker demand growth and less competitive rental markets.
While rising rents provide improved income streams, the Index makes clear that affordability pressures are severe for tenants. Median rents in most capitals now account for a larger share of household income than the long-term average. For landlords, this is a reminder that sustainable rental growth depends on maintaining affordability and ensuring tenants are not priced out. Policy measures around rental assistance and housing supply will likely influence conditions over the coming year.
From an investment perspective, landlords are balancing stronger rental yields against higher borrowing costs. Mortgage repayments remain elevated following interest rate rises in recent years. This is limiting new investor entry, even as existing landlords benefit from improved yields. For those holding property, rental income is providing a crucial offset, though many landlords are cautious about further rate movements.
Looking ahead, the divergence between markets is expected to remain. Sydney and Melbourne are likely to see steady but constrained rental growth, while Brisbane, Perth and Adelaide offer stronger yield prospects. Regional markets, having experienced extraordinary demand through the pandemic years, are levelling out as affordability challenges weigh on tenants and new supply gradually returns.
For landlords, the September data underscores the resilience of rental demand but also highlights the importance of balancing financial returns with tenant capacity. Rental markets are likely to remain competitive, but affordability limits will play a greater role in shaping outcomes through the rest of 2025.

Trends Driving Tenant Demand
Understanding how market conditions influence rental demand is critical for landlords aiming to maximise returns. Shifts in interest rates, population growth, employment and housing supply all play a role in shaping tenant behaviour.
When interest rates rise, home ownership becomes less affordable. This typically increases demand for rental housing as more households remain tenants for longer. Similarly, strong population growth through migration adds pressure to already tight rental markets, particularly in capital cities. For landlords, these conditions can reduce vacancy periods and support stronger rental yields.
Employment trends also matter. Areas with robust job markets attract tenants seeking proximity to work, while regions with weaker economies may experience softer rental demand. Infrastructure projects, such as new transport links, can further boost interest in certain suburbs, lifting competition for rental properties.
On the supply side, low levels of new housing construction intensify competition for available rentals. Conversely, high levels of apartment development can temporarily ease pressure and limit rent growth.
Monitoring these market forces is essential. By staying informed, you can adjust rental expectations, target tenants and plan investment strategies that remain resilient regardless of broader economic conditions.
Strategies for sustainable portfolio growth
Building and managing a property portfolio is a long-term exercise that requires foresight, discipline and sound decision-making. For landlords, growth is not only about adding properties but also about ensuring each investment continues to perform and align with financial goals.
The first step in planning for growth is setting clear objectives. Ask yourself what you want your portfolio to achieve. Are you focused on rental yield to supplement income, or capital growth to build long-term wealth? The answer determines the types of properties and locations that will best suit your strategy.
Diversification is another cornerstone of success. Spreading investments across different property types, price points and locations reduces risk. For example, combining metropolitan apartments with regional houses can balance yield and growth potential. Similarly, considering both residential and commercial assets may offer stability through varying market cycles.
Financing strategy is equally important. Regularly reviewing loan structures ensures you are minimising interest costs and maximising flexibility. Interest-only loans may offer short-term relief, but principal-and-interest repayments help reduce debt and increase equity over time. Access to equity can then be used to fund additional purchases.
Monitoring market conditions allows landlords to act decisively. Population growth, infrastructure development and employment trends all shape rental demand and price performance. Staying informed means you can identify suburbs or regions with strong fundamentals before prices escalate. Conversely, recognising oversupplied markets early helps avoid stagnant growth and rental competition.
Property maintenance and tenant management should never be overlooked. A well-maintained property retains value, attracts quality tenants and reduces costly vacancies. Establishing clear lease agreements, maintaining strong landlord–tenant relationships and conducting regular inspections all contribute to consistent returns.
Tax planning is another key consideration. Understanding how to structure ownership, manage deductions and plan for capital gains is critical. Professional advice ensures compliance while optimising outcomes. Many landlords benefit from engaging both a financial adviser and accountant who specialise in property investment.
Long-term growth also relies on patience. Property is a cyclical asset, and markets will inevitably experience periods of slower growth. Avoid the temptation to react hastily to short-term fluctuations. Instead, focus on fundamentals and your original investment objectives. Holding through downturns often positions investors to benefit when conditions improve.
Technology now plays a larger role in managing portfolios. Digital tools provide real-time insights into rental markets, yield comparisons and cash-flow projections. Landlords who leverage these resources are better equipped to make informed decisions and respond to changes quickly.
Finally, succession and exit planning should be part of your strategy. Consider how your portfolio will support retirement goals or be transferred to family members. Clear planning avoids rushed sales or tax surprises later.
A successful property portfolio grows not just through acquisition but through active management, careful planning and a focus on sustainability. By aligning goals with market realities and maintaining discipline, landlords can build a resilient asset base that delivers both income and security for decades.
