Blocks of units in Blackburn South represent one of Melbourne’s quieter but genuinely compelling multi-tenancy opportunities, combining a leafy middle-ring location with a solid rental demographic and land values that still sit below comparable inner-east suburbs. If you are researching blocks of units Blackburn South as a portfolio addition or development play for 2026, this guide covers every number you need.
What Exactly Are Blocks of Units in Blackburn South, and Why Do Investors Look There?
A block of units is a single land title containing three or more self-contained dwellings, sold as one asset. The buyer receives multiple rental income streams, one rates notice, and one insurance policy — scaling the economics of residential property without the complexity of a commercial transaction.
Blackburn South sits in the City of Whitehorse, roughly 18 kilometres east of Melbourne’s CBD. The suburb is bounded by Blackburn Road, Canterbury Road, and the Dandenong Creek trail corridor, which makes it attractive to families and long-term tenants who value greenery and school catchments. That stability is precisely what block-of-units investors want: low vacancy, predictable rent, and a tenant base that renews rather than churns.

What Do the Numbers Say About Blackburn South Property in 2026?
Grounding any investment decision in verified data is non-negotiable. Below are the figures Collings Real Estate draws directly from DataVic/REIV (via the Collings CRM) and the ABS Census 2021.
Median Sale Prices (April to June 2025 Quarter)
- Median house price: $1.37 million (quarter-on-quarter change: +3.5%; year-on-year change: -3.5%)
- Median unit price: $713,000 (quarter-on-quarter change: -1.7%; year-on-year change: -24.2%)
The unit median’s year-on-year movement deserves careful interpretation. A -24.2% YoY shift in a thinly traded suburb often reflects compositional change — that is, fewer premium resales and more standard stock transacting — rather than a collapse in underlying values. Savvy block-of-units buyers treat soft unit medians as an entry opportunity, particularly when the house median is holding firm and even ticking upward (+3.5% QoQ).
Demographics (ABS Census 2021)
- Population: 10,939
- Median age: 42.0 years
- Median household income: $1,861 per week
- Median rent: $410 per week
A median household income of $1,861 per week (ABS Census 2021) places Blackburn South well above the national median, indicating tenants with genuine capacity to meet rental obligations. The median rent of $410 per week per dwelling means a four-unit block could generate approximately $85,280 in gross annual rent at full occupancy — before accounting for any rental growth since the 2021 Census benchmark.
SQM Research’s latest vacancy data for the Whitehorse local government area consistently records vacancy rates below 2%, which supports the income assumptions above. Tight vacancy is the single most important variable for block-of-units investors because an empty unit does not just reduce income — it also flags potential property condition or management issues to future buyers.
What Are the Key Considerations When Buying a Block of Units in Blackburn South?
Zoning and Development Potential
Much of Blackburn South sits within the Neighbourhood Residential Zone (NRZ), which caps residential density and limits built form height to 9 metres. Investors targeting redevelopment should obtain a planning certificate (Section 32 Vendor Statement) and confirm whether an overlay — such as a Significant Landscape Overlay covering the creek corridor — applies to the specific site. General Residential Zone (GRZ) pockets exist closer to major roads and offer more flexibility for future development.
Scale Advantages of Multi-Tenancy Ownership
Owning a block rather than individual strata units produces several structural advantages:
- Single-point property management — one agent, one ledger, one routine inspection schedule
- Body corporate control — as sole owner you set maintenance standards and budgets without committee votes
- Insurance efficiency — one landlord policy covers all dwellings, typically at a lower per-unit premium than separate policies
- Future strata subdivision — many existing Blackburn South blocks were built on lots that qualify for subdivision under current Whitehorse planning rules, potentially unlocking significant capital gain on exit
For a wider discussion of how these scale advantages compare across Melbourne’s middle ring, see the Collings guide on Blocks of Units Investment and Development Opportunities.
Due Diligence Checklist
- Confirm the title type: Torrens (one lot), Company Share, or stratum. Each carries different financing implications.
- Review current leases — are tenancies periodic or fixed term, and do rents reflect current market rates?
- Commission a building inspection that specifically covers common-area infrastructure: roofing, gutters, shared drainage, and any asbestos registers.
- Obtain a depreciation schedule estimate before purchase — older Blackburn South blocks often carry substantial deductible plant and equipment that meaningfully improves after-tax cash flow.
- Check Council infrastructure contribution requirements if you plan any future subdivision or additional dwelling.
Financing a Block of Units
Lenders treat blocks of units differently depending on unit count. Most major banks will fund a three-to-four unit block on residential lending terms, but once a block reaches five or more units, commercial lending criteria typically apply — requiring a larger deposit (often 30-35%) and serviceability assessment based on rental income rather than personal income alone. Confirm your broker’s experience with multi-tenancy residential assets before proceeding.
