5 High Cash Flow Property Types in Melbourne, Ranked by a Team That's Done All of Them

A $700K house in Melbourne renting at $900 per week. A 6.3% gross rental yield in a market where the average is 3.5%. That's not a headline. That's our actual average performance across the portfolio 1.

The question I get most often is: how?

The answer isn't one strategy. It's five different strategies, each with different risk profiles, capital requirements, management intensity, and return characteristics. Our team has executed all five — not in theory, not on spreadsheets, but with real money, real tenants, and real settlements.

I'm going to rank them from most recommended to least, with the real numbers and the real pain points that most YouTube videos conveniently skip. This isn't a theory exercise. It's a field report.

Type 1: Dual occupancy / dual living (our top recommendation)

This is our favourite strategy, and it's not even close.

Dual occupancy means one block of land with two independent dwellings under one roof — separate entrances, separate kitchens, separate living spaces, separate parking. You rent each dwelling independently and collect two income streams from a single asset.

The numbers on our actual deals: purchase price $700K-$800K for a property that already has dual living configuration (main house + converted rear or side dwelling). Combined rent: $900-$1,100 per week. Gross yield: 6-7% without any additional construction 2.

Why we prefer this over building from scratch: when you buy an existing dual occupancy property, the land value ratio stays high — typically 80%+ because you're paying for the land in a growth corridor, not for the construction of a new dwelling. When you build a dual occupancy from scratch, the construction cost ($250K-$400K) pushes the land ratio below 50%, which undermines long-term capital growth.

The difficulty is sourcing. These properties are rare on-market because their owners know they're cash flow machines. We find most of ours through our off-market network — selling agents who know we'll close quickly and who call us when a dual occupancy listing hits their desk. In some months, we buy 3-4 of these without any of them ever appearing on Domain or realestate.com.au.

Drawback: limited supply. You can't force this strategy — you have to wait for the right property to appear. But when it does, it's the best risk-adjusted cash flow play in Melbourne's growth corridors.

Dual occupancy and dual living are becoming more common across Tasmania, Queensland, and European cities. It's a global trend, not a local novelty. But in Melbourne's southeast, where the land values are growing 7%+ annually, it's especially powerful.

Type 2: Properties with granny flat potential

Since 2024, Victoria has relaxed granny flat regulations — dwellings under 60sqm no longer require a planning permit in most zones 3. This has opened up a massive opportunity for investors who buy a standard house on 500sqm+ and add a granny flat in the rear yard.

Our typical build: 2-bedroom granny flat, 55-58sqm, on a 600sqm+ block. Build cost: $110,000-$160,000 through our internal construction team. Construction timeline: 12-16 weeks. Additional rent: $340-$370 per week 3.

Combined with the main house rent of $500-$550 (pre-renovation baseline), a granny flat pushes total weekly rent to $840-$920. On a $650K purchase + $110K build ($760K total investment), that's a gross yield of 5.7-6.3%. Not quite as strong as dual occupancy, but you can create this outcome on virtually any property with adequate land size, whereas dual occupancy requires finding an existing configuration.

Important caveat: banks typically don't fully recognise granny flat value in valuations. If you build a $110K granny flat, the bank might add $40-60K to the property's assessed value — not the full construction cost. This means your equity position is initially worse than the cash flow suggests. The payback period on a granny flat, purely from the bank's equity perspective, is typically 3-5 years. From a cash flow perspective, the granny flat pays for itself in approximately 6 years at $350/wk rent.

The ROI is still strong — 18% gross return on the construction cost — but set expectations correctly. This is a medium-term strategy, not an instant equity play.

We've built over 47 granny flats across Melbourne's southeast. The numbers are consistent. The strategy works. But it works over 3-5 years, not overnight.

Type 3: Rooming house conversion

Rooming houses — where each bedroom is rented independently to separate tenants — produce the highest gross yields of any residential strategy. We've achieved 8%+ gross yield on multiple conversions 4.

The typical setup: buy a large 3-4 bedroom house, invest $50,000-$80,000 in compliant conversion (additional bathrooms, fire safety, disability access ramp, commercial-grade kitchen), and rent each room for $180-$250 per week. A 4-bedroom conversion generating $200/room produces $800/week. A 6-bedroom conversion (adding rooms through internal reconfiguration) can hit $1,200/week.

Our Narre Warren case study: purchased under $800K, invested $80K in heavy conversion (added kitchen, laundry, physical partitions), achieved $1,200 per week rent — a yield approaching 8% 4.

The drawbacks are real and significant:

1. Management intensity. Room-by-room tenancies mean higher turnover, more inspections, more maintenance requests, and more potential for tenant conflicts. Our PM team manages rooming houses at a lower property-to-manager ratio than standard rentals.

2. Council compliance. Victoria requires rooming house registration for properties with 4+ unrelated tenants. Compliance costs include annual fire safety checks, disabled access modifications, and ongoing council inspections. Some councils are aggressive about enforcement.

3. Bank valuation. Banks are conservative with rooming house valuations. The per-room rental premium often isn't reflected in the bank's assessed value, which limits refinancing capacity.

4. Resale. Rooming houses are harder to sell because the buyer pool is smaller — only experienced investors understand the model. A standard house listing attracts families, investors, and developers. A rooming house listing attracts a fraction of that market.

Rooming houses work brilliantly for investors who want maximum cash flow and have the management capacity (or a PM team like ours) to handle the operational complexity. For passive investors, this strategy is too demanding.

Type 4: Short-term rental (Airbnb)

Short-term rental through platforms like Airbnb can generate premium nightly rates — particularly for properties near beaches, wine regions, or event venues. A property that rents for $500 per week on a standard lease might generate $200 per night on Airbnb during peak season.

But the numbers aren't as good as they look.

Management fees for short-term rentals in Melbourne average 20% of gross revenue — versus 7-8% for standard property management 5. Occupancy rates fluctuate seasonally and can drop to 40-50% during winter or during events like COVID lockdowns. Cleaning costs between guests ($80-$150 per turnover) add up fast. Linen, consumables, and higher wear-and-tear increase your annual maintenance budget by 30-50%.

And starting soon, Victoria is adding a 7.5% levy on short-term rental income 5. That's on top of the existing GST obligations if your annual Airbnb revenue exceeds $75K.

After all costs, a well-managed short-term rental might net 10-15% more than a standard lease — not the 100% premium the gross nightly rates suggest. For the additional management complexity, regulatory risk, and seasonality exposure, we don't recommend this strategy for most investors.

Exception: holiday properties in established tourism corridors (Mornington Peninsula, Great Ocean Road) where the short-term rental premium is sustained year-round and the property doubles as personal use during off-peak. But that's a lifestyle-investment hybrid, not a pure investment strategy.

Why the land ratio matters as much as the yield

Before I close, let me address the single biggest mistake investors make when chasing high cash flow: they forget about land ratio.

Yield and land ratio are in constant tension. The easiest way to boost yield is to add more building — more rooms, more bathrooms, more constructed area. But every dollar of construction adds to the building component and reduces the land-to-price ratio.

A brand-new duplex on a 400sqm block might have an impressive 7% yield. But the land ratio might be 40% — meaning 60% of your purchase price is paying for depreciating construction. Over 10 years, the building loses 20-30% of its value through physical depreciation while the land grows at 7%. Your net growth rate is dragged down by the depreciating component.

Contrast this with our preferred approach: buy an older house on 600sqm+ where 80-85% of the price is land. The existing structure is already depreciated — the price is mostly dirt. Do a $10-15K cosmetic renovation (paint, carpet, landscaping) to push rent from $500 to $850 per week 1. The yield improvement comes from operating efficiency, not construction. And the land ratio stays at 80%+, meaning 80% of your asset is growing at the full 7% rate.

Our $585K purchase in Case Study #7 illustrates this perfectly: $13K in cosmetic work pushed rent from $550 to $950/wk. Six months later, the bank revalued at $710K. That's a $125K equity gain from $13K spent. The yield is spectacular (8.4% gross). The land ratio stayed above 80%. And the total improvement cost was less than a new bathroom renovation.

This is why we don't recommend building new dual occupancies, rooming houses, or granny flat-focused purchases where the construction component dominates. We recommend buying existing configurations with land-heavy pricing, then optimising cash flow through operational improvements — better presentation, smarter tenant selection, room reconfiguration — rather than new construction.

The ideal outcome is high yield AND high land ratio. It's harder to achieve, but it's where the real wealth is built. High yield without land ratio is a cash flow trap — you're earning income on a depreciating asset. High land ratio without yield is a negative gearing play — you're betting entirely on growth.

The sweet spot is 5.5-6.5% yield on 80%+ land ratio. That's what we target on every acquisition. And it's what makes Melbourne's southeast corridors — where older houses on large lots can be lightly renovated for yield while the land compounds at 7%+ — the best risk-adjusted property market in Australia.

The hidden Type 6 that we don't tell everyone about

I said five types, but there's actually a sixth that we don't talk about publicly very often because it requires specific conditions and not everyone should attempt it.

Dual-key conversion: taking an existing house and creating two physically separate living spaces within the same structure — each with its own entrance, kitchen, and bathroom — without triggering council planning permits.

The key is understanding what requires a permit and what doesn't. In Victoria, internal modifications that don't change the external footprint, roofline, or structural load generally don't require a building permit for the renovation work itself (though electrical and plumbing certifications are always required). Converting a window to a door on the side of a house is a minor works category. Adding an internal wall to separate a living space is a standard renovation.

Our Hampton Park case study (34 Cairns) demonstrates this perfectly: purchase under $760K, internal modification to create two independent living spaces with separate entrances, achieving $900/wk combined rent 4. The "window-to-door" technique created a separate external entrance for the secondary dwelling without triggering a planning assessment.

The legal nuance matters enormously here. You're not creating a second dwelling — you're modifying an existing single dwelling. The property remains a single title, single dwelling in the council's records. But functionally, it operates as two independent rental units.

I hesitate to write about this publicly because the technique requires precise understanding of the Building Code, the Planning Scheme, and the boundary between renovation and development. Done correctly, it's perfectly legal and incredibly profitable. Done incorrectly — accidentally triggering a planning permit requirement by changing the external facade too much, or exceeding the threshold for a building permit — it creates a compliance liability that can cost $10,000-$50,000 in fines and rectification.

This strategy is not for DIY investors. It's for experienced operators with teams who know exactly where the regulatory lines are. But if you have that team, dual-key conversion is the most capital-efficient way to double your rental income on a single property.

Type 5: Commercial property

Commercial property — retail shops, offices, industrial units, medical centres, childcare facilities — operates in a fundamentally different universe from residential.

The upside: net yields of 4-10%. Triple-net leases where the tenant pays all outgoings (rates, insurance, maintenance). Longer lease terms (3-10 years with options). Lower management intensity once tenanted.

The downside: everything else.

Commercial property requires 35-40% deposit (versus 20% residential). LVR is capped at 60-65%. Interest rates are typically 1-2% higher than residential. Vacancy periods can be extended — a vacant retail shop in a suburban strip might take 6-12 months to re-tenant, versus 2-3 weeks for a residential property in Melbourne's southeast 6.

Commercial values are directly tied to the local economy. A recession that merely slows residential prices can slash commercial values by 20-30%. Tenant default risk is higher. And the buyer pool at sale is smaller and more sophisticated — no emotional first-home buyers competing for your asset.

Commercial property has a role for investors who have maxed out their residential borrowing capacity but still have cash. It's a parking spot for surplus capital. But it's not where you build the foundation of a wealth-building portfolio.

Build the residential foundation first. Add commercial later, if ever. The residential market in Melbourne's southeast — with its 1.2-1.5% vacancy, 7%+ growth, and ability to add granny flats for instant yield uplift — offers a better risk-adjusted return than commercial for 90% of investors.

We've done all five. We recommend starting with Type 1 or Type 2. Graduate to Type 3 when you have the management infrastructure. Use Type 4 and 5 sparingly, if at all.
