Blocks of units under $4m represent one of the most compelling entry points into commercial-scale residential property investment in Melbourne right now. For investors who want genuine rental income, meaningful land content, and long-term capital growth without stretching into the $10m-plus trophy-asset category, the sub-$4m unit-block market is where the real action is in 2026.

This guide breaks down what your budget actually buys, which Melbourne suburbs offer the strongest fundamentals, what kind of yields to expect, and how Collings Real Estate consistently sources these assets — including a significant share that never reach the public portals.

What Do Blocks of Units Under $4m Actually Buy in Melbourne in 2026?

The honest answer depends heavily on location, but the sub-$4m bracket is broader than most investors assume. CoreLogic data from early 2026 indicates that the median price for a residential unit block (4 or more dwellings) transacted in metropolitan Melbourne sits at approximately $2.6m, meaning a $4m ceiling gives buyers genuine optionality across a wide ring of suburbs.

Here is a realistic breakdown of what the budget buys by property type:

• 4-to-6 unit blocks in middle-ring suburbs (10–20km from CBD): Typically brick, 1960s-to-1980s construction, on land parcels of 600–1,000 sqm. Suburbs like Reservoir, Preston, Heidelberg, Coburg, and Brunswick East regularly feature in this range.
• 3-unit blocks in inner suburbs (5–10km from CBD): Older Californian bungalow conversions or purpose-built walk-ups in Northcote, Fitzroy North, Thornbury, and Fairfield. Land content is strong, and repositioning upside is substantial.
• 6-to-10 unit blocks in outer-ring or regional centres: Geelong, Ballarat, Bendigo, and Frankston offer older, higher-yielding blocks at lower per-unit entry costs — often under $400,000 per door.
• Development-ready sites with existing income: Some sub-$4m opportunities include a small existing block on a site zoned for higher density, allowing investors to collect rent while pursuing a planning permit.

What Rental Yields Can Investors Expect from a Sub-$4m Unit Block?

Yield is the metric that separates a good unit-block acquisition from a great one. According to SQM Research’s June 2026 figures, residential vacancy rates across metropolitan Melbourne sit at approximately 1.2% — a historically tight level that underpins strong rental demand and limits the risk of extended vacancy between tenants.

Gross rental yields for unit blocks in the sub-$4m category typically range as follows:

• Inner suburbs (within 10km of CBD): 4.0% to 5.5% gross yield. Land value is the dominant driver of total return here, so lower yields are offset by stronger capital growth prospects.
• Middle-ring suburbs (10–20km from CBD): 5.0% to 6.5% gross yield. The sweet spot for most investors seeking a balance of income and growth. Suburbs like Reservoir, Heidelberg West, and Coburg consistently perform in this band.
• Outer-ring and regional: 6.5% to 8.5% gross yield. Higher income, but buyers should stress-test capital growth assumptions and factor in potentially higher maintenance costs on older stock.

Net yields after expenses (rates, insurance, property management, maintenance, and vacancy allowance) typically sit 1.5 to 2.0 percentage points below gross. A block generating 6% gross in a middle-ring suburb is likely to net 4.0% to 4.5% — still materially stronger than most single residential dwellings.

What Drives Yield Compression in This Asset Class?

Several structural factors are pushing yields tighter across Melbourne’s unit-block market in 2026:

1. Surge in investor demand: With interest rates stabilising after the RBA’s easing cycle, more buyers are re-entering the market with equity to deploy.
2. Chronic undersupply of rental stock: The 2024-2026 construction downturn has left Melbourne’s rental pipeline significantly below demand levels. ABS building approval data shows multi-unit approvals in Victoria fell 18% in the 12 months to March 2026 compared to the prior period.
3. Strong interstate and overseas migration: Melbourne’s population grew by approximately 120,000 people in the 2024-25 financial year according to Victoria’s Department of Transport and Planning, sustaining rental demand across all price points.

Which Melbourne Suburbs Offer the Best Value for Blocks of Units Under $4m?

Not all suburbs perform equally, and identifying undervalued pockets before broader market recognition is the key to superior returns. Based on a combination of CoreLogic median price growth data, SQM vacancy rates, and Collings’ own transaction history, the following suburbs stand out in 2026:

Inner North

Northcote, Thornbury, and Preston sit at the intersection of strong tenant demand, infrastructure investment (Suburban Rail Loop precinct influence), and genuine land scarcity. Median unit values in Northcote grew 7.2% in the 12 months to April 2026 (CoreLogic). A 3-unit block on a large allotment in Northcote can still be sourced under $3.5m, with scope to add a fourth dwelling subject to planning. Our blocks of units for sale in Northcote page showcases current and recent opportunities in this corridor.

Inner West

Footscray, Seddon, and Yarraville continue to attract strong tenant demand driven by proximity to the CBD (6-10km), the West Gate Tunnel’s improved connectivity, and a vibrant cafe and retail strip. Unit blocks in this corridor are increasingly competitive but sub-$4m opportunities still exist, particularly for older walk-up stock in need of cosmetic renovation.

Middle-Ring North and North-East

Reservoir, Heidelberg, Heidelberg West, and Bundoora offer the most consistent volume of sub-$4m unit blocks in Melbourne. Vacancy rates in Reservoir sit at just 0.9% (SQM Research, May 2026), making it one of the tightest rental markets in the city. Typical 4-unit blocks here trade between $2.2m and $3.4m depending on condition and land area.

South-East Corridor

Cheltenham, Moorabbin, and Mentone are seeing renewed investor interest following the confirmed Suburban Rail Loop alignment. Land values along this corridor have moved 9.1% in the 12 months to March 2026 (CoreLogic), and existing unit blocks offer a way to secure quality land with immediate rental income while planning timelines play out.

How Does Collings Real Estate Source Off-Market Unit Blocks?

One of the most common questions Collings receives from investors in the sub-$4m unit-block category is: “How do I find these properties before they hit the portals?” The answer lies in relationships, specialisation, and a database that has been built over decades of operating exclusively in this asset class.

Collings Real Estate has been selling blocks of units in Melbourne since 1975. That longevity creates an unmatched network of vendor relationships — landlords who have owned their block for 20 or 30 years and want a discreet, efficient sale without the disruption of a public marketing campaign. A significant proportion of Collings’ annual unit-block transactions are completed entirely off-market or through targeted buyer-matching before formal listing.

How the Off-Market Process Works

1. Buyer registration: Investors register their specific criteria (location, budget, minimum units, yield requirements, development appetite) with the Collings team.
2. Proactive vendor outreach: Collings directly approaches owners of suitable blocks — many of whom are existing clients from the property management division — to gauge selling interest.
3. Confidential introduction: Qualified buyers are introduced to the property and vendor before any public marketing is considered.
4. Structured due diligence support: Collings coordinates access to tenancy schedules, outgoings summaries, and building reports to streamline the buyer’s assessment process.

This model consistently delivers outcomes that the open market cannot replicate: buyers access properties with less competition, vendors achieve a smooth process with minimal disruption to tenants, and transactions complete more efficiently for all parties.

What Due Diligence Should Buyers Conduct on a Sub-$4m Unit Block?

Acquiring a block of units is fundamentally different from buying a single residential property. The due diligence process is more involved, and skipping steps can be costly. Here is a practical checklist for buyers operating in the sub-$4m range:

• Tenancy schedule review: Confirm current rents, lease start and expiry dates, bond amounts, and whether any tenancies are periodic. Compare current rents to market rates to identify under-renting.
• Outgoings audit: Obtain 24 months of council rates, water rates, insurance premiums, and maintenance expenditure. Older stock often carries higher maintenance costs that are not immediately apparent.
• Building and pest inspection: Essential for 1960s-to-1980s brick construction. Common defects include rising damp, asbestos-containing materials (particularly in eaves, laundries, and wet areas), and ageing electrical switchboards.
• Planning and zoning check: Confirm the current zone (Neighbourhood Residential Zone, General Residential Zone, Residential Growth Zone) and whether there are any overlay controls (Heritage, Vegetation, Design and Development) that affect future development potential.
• Strata and title check: Confirm whether units are on a single title (preferred for flexibility) or subdivided into individual strata titles, which has different implications for future sales strategy.
• Comparable market analysis: Review recent comparable block sales within a 2km radius over the past 18 months to validate pricing and assess whether the asking price reflects current market conditions.

Is Now a Good Time to Buy Blocks of Units Under $4m in Melbourne?

Market timing is always imperfect, but several converging factors make 2026 a particularly well-supported entry point for sub-$4m unit-block buyers in Melbourne:

• Interest rate trajectory: The RBA cut the cash rate by 75 basis points between late 2025 and mid-2026, reducing holding costs and improving serviceability for investment loans. AMP Capital’s chief economist forecasts one further cut in the second half of 2026.
• Rental market tightness: With vacancy rates at multi-decade lows across most Melbourne suburbs, the risk of holding a partially vacant block is at its lowest point in years.
• Supply constraints: The construction cost environment remains challenging for new multi-unit development, meaning existing blocks face limited new competition in the short to medium term.
• Pre-development land plays: Suburbs within the Suburban Rail Loop corridor and designated Activity Centres (under Plan Melbourne 2024 updates) are being rezoned for higher density, creating potential step-changes in land value for existing block owners who hold through the planning cycle.

None of these factors guarantee outcomes, and investors should always obtain independent financial and legal advice before proceeding. However, the structural case for well-located Melbourne unit blocks as a long-term wealth-building asset remains as strong as it has been at any point in the past decade.

Conclusion

The sub-$4m unit-block market in Melbourne offers genuine breadth in 2026 — from inner-suburb three-packs with development upside to middle-ring six-unit blocks delivering 6%-plus gross yields. With rental vacancy at historic lows, population growth sustaining demand, and interest rates easing, the fundamental case for this asset class is compelling.
