Blocks of units in Oakleigh South represent one of Melbourne’s southeast corridor’s most compelling multi-income investment formats, combining a tightly held residential market with strong rental demand and genuine land-value upside. If you are searching for a unit block in this suburb, this guide covers everything you need to make a well-informed decision in 2026.

What Are Blocks of Units in Oakleigh South and Why Do Investors Target Them?

A block of units is a single title — or a group of titles on one lot — containing multiple self-contained dwellings. Investors pursue them because the asset delivers multiple rent streams from a single acquisition event, meaning transaction costs are spread across a higher income base than a single-dwelling purchase could achieve.

Oakleigh South sits roughly 17 km southeast of Melbourne’s CBD, bordered by Oakleigh, Huntingdale, and Bentleigh East. The suburb’s grid of streets, good access to the Monash Freeway, and proximity to Monash University make it a perennial favourite for renters. According to ABS Census 2021 (via CRM Brain) figures, the suburb recorded a population of 9,851 with a median age of 40.0 years and a median household income of $1,915 per week. That income profile supports a tenant base capable of absorbing rental increases, which is exactly the kind of demand signal a unit-block investor wants to see before committing capital.

What Do the Numbers Say About Oakleigh South Property in 2026?

Hard data is what separates a confident investment decision from speculation. Here is what the current figures show for Oakleigh South property.

Median Sale Prices

Per DataVic/REIV (via CRM Brain) figures for the April to June 2025 quarter:

• Median house price: $1.25 million (quarter-on-quarter: -2.0%; year-on-year: +6.4%)
• Median unit price: $815,000 (quarter-on-quarter: -1.5%; year-on-year: +7.2%)

The unit segment is outpacing houses on an annual basis, with a 7.2% year-on-year gain recorded to June 2025. Short-term softness in any given quarter is normal in a suburb with low transaction volumes; the annual trajectory is the number that matters most for a hold-and-income strategy.

Rental Market

According to ABS Census 2021 (via CRM Brain), the median weekly rent in Oakleigh South was $418 per week. CRMBrain 2026 data puts the current median weekly rent at $410 per week, reflecting a stable rental floor across the suburb. For a block of, say, four units all achieving rents in this range, the gross annual rental income would sit near $85,280 before expenses — a meaningful income yield relative to a mid-market acquisition price.

Supply Scarcity

Per CRMBrain 2026 data, there is currently only 1 property on the market in Oakleigh South at the time of writing. That extreme scarcity of listed stock is a defining feature of this suburb’s investment case. When supply is constrained, off-market transactions become not just an option but often the only pathway for serious buyers.

Active Buyer Demand

Demand signal data from doma_demand_signals (via CRM Brain) identifies active buyer demand for units and townhouses in Oakleigh South right now. Even with thin listed supply, motivated buyers are registered and ready to transact — which also has implications for any investor who decides to exit their position in future.

Environmental and Amenity Context

Per GeoRisk 2026 data, the suburb carries minimal flood risk and sits within reasonable proximity to 71 aged-care facilities within a 5 km radius — a figure that underlines the area’s appeal to a broad demographic of residents and, by extension, tenants. Air quality at the nearest monitoring station (Brighton) records a PM2.5 reading of 14.54 µg/m³, rated Fair, which is consistent with a liveable inner-southeast suburb.

Understanding rental yield in the context of Melbourne’s broader southeast is also worth doing. Collings’ rental yield Melbourne guide ranks suburbs by gross yield so you can benchmark Oakleigh South against comparable locations before committing.

What Are the Key Considerations When Buying a Block of Units in Oakleigh South?

Buying a multi-dwelling asset involves more layers of due diligence than a standard residential purchase. Here are the critical factors to work through before signing a contract on Oakleigh South property.

Title Structure and Strata Implications

Unit blocks can be held on a single Torrens title, a company share title, or in stratum/strata configurations. A single Torrens title gives the investor full control and the greatest flexibility to redevelop or sell in one line. Strata titles introduce owners corporation obligations and can complicate a future sale or development application. Clarify the title structure before proceeding.

Zoning and Development Potential

Much of Oakleigh South is zoned General Residential (GRZ) under the Monash Planning Scheme, with some pockets of Neighbourhood Residential (NRZ) applying stricter height and density controls. If a potential block of units sits in a GRZ precinct, there may be scope to add dwellings or undertake value-add works subject to council approval. Confirm the exact zone and any overlay, including heritage considerations — GeoRisk 2026 notes that the suburb sits within a heritage overlay, though no heritage-listed items exist within 2 km.

Building Condition and Capital Expenditure

Many Oakleigh South unit blocks were constructed in the 1960s and 1970s. A pre-purchase building and pest inspection plus a detailed structural report should be non-negotiable. Budget conservatively for roof maintenance, plumbing upgrades, and common-area works. Hidden capital expenditure can quickly erode a yield advantage that looked compelling on paper.

Tenancy Status and Rental Income Verification

Obtain current lease agreements, rental histories, and bond lodgement records for every dwelling in the block. Cross-reference actual rents against the $410 per week suburb median (CRMBrain 2026) to assess whether the income is at market, below market with upside on lease renewal, or already at the ceiling. Below-market rents can be an opportunity; above-market rents that are unsustainable are a risk.

Finance Structure

Lenders treat multi-dwelling assets differently from single-dwelling residential properties. Loan-to-value ratios are often lower, particularly for blocks of four or more units. Engage a finance broker experienced in commercial and multi-residential lending before making an offer, so your borrowing capacity and structure are confirmed in advance.
