Blocks of units in Harkness represent one of Melbourne’s west’s most compelling multi-tenancy investment opportunities in 2026, offering investors scale, strong rental demand, and a young, growing tenant base in a suburb that continues to attract owner-occupiers and renters alike. This guide covers everything you need to know before buying a unit block in Harkness, from the latest price and yield data to the practical steps of securing a property.

What Exactly Are Blocks of Units in Harkness, and Why Do Investors Target This Suburb?

A block of units is a single title (or sometimes a group of strata titles) that contains two or more self-contained residential dwellings under single ownership. In Harkness, these assets typically take the form of older brick walk-up complexes or newer townhouse-style groups situated on relatively generous land allotments in Melbourne’s outer west corridor, roughly 40 kilometres from the CBD.

Investors target Harkness for several structural reasons:

• Young, high-density rental demand: ABS Census 2021 records a median age of just 30.0 years in Harkness, meaning the suburb skews strongly toward renters who are yet to purchase their first home.
• Solid household incomes: ABS Census 2021 data shows a median household income of $1,752 per week, supporting consistent rent payments and limiting vacancy risk.
• Population scale: With a recorded population of 12,463 (ABS Census 2021), Harkness is large enough to sustain ongoing rental absorption even during broader market softness.
• Infrastructure growth: The suburb benefits from proximity to Melton, a designated growth corridor under the Victorian Government’s Plan Melbourne framework, which continues to attract employment nodes and retail infrastructure.

For investors already familiar with blocks of units for sale in Melbourne in 2026, Harkness sits at a price point that allows entry without competing against the deep-pocketed institutional buyers who dominate inner-ring suburbs.

What Do the Numbers Say About Harkness Property Values and Rental Returns?

Precise, suburb-level data is essential when underwriting a unit block purchase. The figures below are sourced from DataVic and REIV data (via Collings Real Estate’s CRM dataset) for the April to June 2025 quarter, and they paint a nuanced picture of the Harkness market.

Median Sale Prices (April to June 2025 Quarter)

• Houses: $590,000 (quarter-on-quarter: +7.8%; year-on-year: +4.8%)
• Units: $400,000 (quarter-on-quarter: +8.1%; year-on-year: -2.4%)
• Land: $298,000 (quarter-on-quarter: +13.3%; year-on-year: -15.5%)

The unit median of $400,000 with a quarterly jump of +8.1% signals a recovering unit segment after a period of softness. For block-of-units investors, this is a meaningful signal: individual unit values are compressing toward house values, which historically precedes a re-rating of multi-unit assets on a per-door basis.

Rental Market

ABS Census 2021 data records a median rent of $350 per week across Harkness. Applying that figure across a four-unit block generates a gross passing rent of approximately $1,400 per week, or roughly $72,800 per annum, before vacancy and management costs. At current land and construction values, this makes unit blocks one of the few residential formats in Melbourne’s west that can approach commercially viable gross yields without relying on speculative rent growth assumptions.

When benchmarked against broader Melbourne investment data, Harkness competes well. If you want to compare suburb yields side by side, the Collings guide to high rental yield suburbs in Melbourne for 2026 provides a comprehensive ranking of where the numbers stack up best.

Why Scale Matters for Unit Block Investors

A single rental property in Harkness delivers one income stream. A four-unit block delivers four, meaning that a single vacancy reduces gross income by only 25% rather than 100%. This risk-smoothing effect is the core argument for multi-unit investment over single-dwelling property, and it becomes even more powerful in a suburb like Harkness where tenant demand is broad rather than niche.

What Are the Key Considerations Before Buying a Unit Block in Harkness?

Unit blocks are not plug-and-play investments. They carry specific due-diligence requirements that single-dwelling buyers rarely encounter.

Title Structure and Planning Overlays

Harkness sits within the Melton City Council municipality. Before exchanging contracts, buyers should confirm whether the block is held on a single title (preferred for resale flexibility) or individual strata titles, and check whether any planning overlay applies to the land. The Melton Planning Scheme includes several residential growth zones where additional density may be permissible, which can materially affect the asset’s development upside.

Building and Pest Reports

Older brick walk-up blocks common to Melbourne’s western suburbs can conceal significant remediation costs: cracked render, rising damp, aging switchboards, and asbestos in pre-1990 construction. Budget for a thorough building inspection across every tenancy, not just the common areas.

Vacancy and Tenancy Mix

Harkness has a young median age of 30, which typically correlates with higher tenancy turnover than suburbs with older demographic profiles. Investors should review current lease terms, bond lodgement records, and payment histories for every existing tenant before settlement.

Financing Considerations

Most major banks treat blocks of more than four dwellings as commercial lending rather than residential, which affects loan-to-value ratios and serviceability assessments. Buyers targeting larger blocks should engage a commercial-property-experienced mortgage broker before making offers, as pre-approval criteria can differ significantly from standard home loan benchmarks.

Land Tax and Holding Costs

Victorian land tax is calculated on the aggregated unimproved value of all investment properties held in a single name or trust. A unit block in Harkness, assessed at land values consistent with the current median of $298,000 per quarter (DataVic/REIV via Collings CRM), may push an investor’s total landholding above relevant land tax thresholds. Seek advice from a property-specialist accountant before exchange.

How Does Collings Real Estate Help Investors Source and Manage Unit Blocks in Harkness?

Collings Real Estate has specialised in multi-tenancy residential investment across metropolitan Melbourne since 1982. The business operates from 230 Waterdale Road, Ivanhoe, VIC 3079, and combines an active sales division with a full-service property management team, meaning investors can transact and manage through a single point of contact.

Off-Market Access

The majority of unit block transactions in Melbourne’s outer west never reach public listing portals. Collings maintains a private off-market register of vendors considering a sale. Investors can register their acquisition criteria, including suburb, price range, minimum number of dwellings, and preferred title structure, through the Collings property portal at collings.com.au/portal to receive matched off-market opportunities before they are offered to the broader market.

Suburb-Level Data and Appraisal

Collings agents can provide independent rental appraisals for each dwelling within a prospective block, drawing on active tenancy data across their managed portfolio in Melbourne’s west and north. This gives buyers a defensible income projection rather than a vendor-supplied estimate.

Property Management Post-Settlement

Once purchased, a unit block in Harkness requires active management: lease renewals, maintenance coordination across multiple tenancies, VCAT representation when required, and quarterly condition reports. Collings’ property management division handles all of these tasks, allowing investors to treat the asset as a passive income vehicle rather than a second job.
