The Blackburn South rental yield for houses sits at approximately 1.56% gross based on a median weekly rent of $410 and a median sale price of $1.37 million recorded in the April to June 2025 quarter. For units, the gross yield is considerably more attractive at roughly 2.99%, derived from the same $410 weekly median rent against a median unit price of $713,000. These figures make Blackburn South a suburb where understanding the full picture, including net yield, vacancy trends and capital growth trajectory, is essential before committing capital.

What Is the Blackburn South Rental Yield Right Now?

Yield is simply the annual rent collected as a percentage of the property’s purchase price. The standard formula is: (weekly rent x 52) / purchase price x 100. Using the most current data available from DataVic and the REIV (via the Collings CRM brain), here is how Blackburn South stacks up for the April to June 2025 quarter:

House Yield Calculation

• Median sale price (houses): $1,370,000
• Median weekly rent: $410
• Annual rental income: $21,320
• Gross yield: 1.56%
• Quarter-on-quarter price change: +3.5%
• Year-on-year price change: -3.5%

Unit Yield Calculation

• Median sale price (units): $713,000
• Median weekly rent: $410
• Annual rental income: $21,320
• Gross yield: 2.99%
• Quarter-on-quarter price change: -1.7%
• Year-on-year price change: -24.2%

These are gross yield figures. Net yield, which accounts for property management fees, council rates, insurance, maintenance and vacancy periods, typically runs 0.5% to 1.5% lower than the gross figure, depending on the property and its condition. For a house yielding 1.56% gross in Blackburn South, a realistic net yield may fall between 0.5% and 1.1%. For a unit at 2.99% gross, net yield is more likely in the 1.5% to 2.5% range.

Investors considering investment properties in Melbourne with higher yield thresholds may want to compare Blackburn South against other established middle-ring suburbs before making a final decision, as yield profiles vary significantly across the metropolitan area.

What Do the Numbers Say About Investing in Blackburn South?

Raw yield numbers only tell part of the story. Context matters enormously, and the demographic and economic profile of Blackburn South adds important colour to the data.

According to ABS Census 2021 data (via the Collings CRM brain), Blackburn South has a population of 10,939 with a median age of 42.0 years. The median household income is $1,861 per week, placing it comfortably above the national median. The median rent recorded in the Census was $410 per week, which aligns closely with current market conditions and suggests rents in the suburb have been relatively stable in recent years.

These demographics point to a suburb with a mature, financially stable resident base. Owner-occupier rates tend to be high in suburbs with this demographic profile, which can mean that rental stock is limited and competition among tenants for available properties is relatively strong. A tighter rental pool can support sustained or rising rents over time, even when gross yield appears modest by comparison with higher-growth outer suburbs.

Capital Growth vs. Yield: The Blackburn South Trade-Off

The unit price drop of 24.2% year-on-year (DataVic/REIV, April to June 2025) is a significant data point that any investor must weigh carefully. While a lower entry price pushes gross yield higher in the short term, a sustained downward price trend can erode total return. Conversely, the house market showed a quarterly gain of 3.5%, suggesting that while values dipped year-on-year, momentum may be stabilising in the detached dwelling segment.

The ATO provides useful context for property investors here: interest costs, depreciation, property management fees and maintenance are all generally deductible against rental income for Australian investors, which means the after-tax net yield can look meaningfully better than the pre-tax figure for investors in higher marginal tax brackets. Investors should always obtain independent tax advice tailored to their own circumstances.

What Are the Key Considerations for Investing in Blackburn South Property?

Before committing to a purchase in Blackburn South, prudent investors should work through a checklist of factors that can significantly affect real-world returns:

1. Property type selection: The gap between house and unit yields (1.56% vs 2.99%) is substantial. Units currently offer stronger income yield, but the sharp year-on-year price decline warrants careful due diligence on the specific building, strata levies and supply dynamics in the immediate area.
2. Vacancy rates: SQM Research tracks vacancy rates by suburb. Investors should check current vacancy conditions in Blackburn South before settling on an expected rental income figure. A vacancy of even two to four weeks per year can reduce effective annual yield by 4% to 8% of the gross figure.
3. Rental demand drivers: Proximity to Box Hill’s commercial and hospital precinct, Whitehorse Road retail, and several well-regarded schools makes Blackburn South attractive to families and professionals. This underpins rental demand for family-sized homes.
4. Maintenance costs: Older dwellings common in established suburbs like Blackburn South can carry higher maintenance costs. A building inspection and a realistic capital expenditure allowance should be factored into any net yield projection.
5. Interest rate environment: The RBA’s rate decisions directly affect the cost of investment lending. As of mid-2026, investors should model their cash flow at both current rates and a moderate upward scenario to stress-test serviceability.
6. Depreciation schedule: For newer units in particular, a quantity surveyor’s depreciation schedule can add meaningful non-cash deductions that improve after-tax cash flow, even where gross yield is modest.

Investors focused specifically on income-generating assets may also want to explore off-market investment properties in Melbourne where competition is lower and purchase prices can sometimes be negotiated below median levels, directly improving yield at entry.

How Does Blackburn South Compare to Similar Suburbs?

Blackburn South sits within the City of Whitehorse, a local government area characterised by strong school zones, good infrastructure and relatively low crime. Neighbouring suburbs such as Blackburn, Mitcham and Vermont South follow similar yield profiles to Blackburn South, with gross yields on houses typically in the 1.5% to 2.2% range and units somewhat higher. For investors prioritising yield over capital growth, inner and middle-ring suburbs with higher density can offer gross yields of 3.5% to 5% or more, though often with a different risk and demographic profile. The key is matching the suburb’s characteristics to the investor’s strategy and holding period.
