# We Turned an $800K Corner Block Into Three Rental Incomes. Total: $900 Per Week.

*By Joey Don, Co-Founder & CEO at PremiumRea — 2026-03-30*

> Corner blocks are not just properties. They are blank canvases for wealth creation. Here is how we turned one into a triple-income machine.

I stood in the backyard of an $800,000 corner block in Melbourne's southeast and saw three rental incomes where most people saw one house.

The property was a standard four-bedroom brick veneer on 620 square metres. Corner position with side-street access — the critical detail that makes everything possible. The main house was tired but structurally sound. The backyard was generous. The side driveway was over 3 metres wide.

Within six months, this property was generating $900 per week across three separate tenant groups. The total investment — purchase plus renovation plus granny flat — came to approximately $930,000. That is a gross yield of 5.0% on a property with future subdivision potential worth an additional $150,000-$200,000 in equity.

Let me walk you through exactly how we did it.

## Step one: the granny flat ($110,000 + GST)

The backyard had direct access from the side street via the existing driveway. This is non-negotiable for granny flat construction — the crane truck that delivers materials needs a minimum 3-metre-wide access path.

We commissioned a 30-square-metre one-bedroom studio. Total construction cost: $110,000 plus GST. The build took approximately 4.5 months from paperwork initiation to occupancy certificate.

Cost breakdown:
- Building permit and surveyor: ~$3,000
- Soil testing: ~$4,400
- Construction (30sqm standard spec): $110,000 + GST
- Sub-meter installation for utilities: $2,000

Under Victorian planning rules, a granny flat under 60 square metres requires no council planning permit — only a building permit. This eliminates months of approval delays and thousands in planning consultant fees.

Once the OC was issued, we listed the granny flat for rent at $370 per week including bills. It was leased within 8 days to a single professional. The sub-meter allows us to monitor actual utility consumption while bundling an estimated $30/week into the headline rent — a model that typically nets the landlord a small surplus.

## Step two: the main house reconfiguration ($12,000)

The main house had four bedrooms, two bathrooms, and a separate living area at the rear. We reconfigured the internal layout to create two distinct living zones — a technique we call dual-key or one-into-two.

The work involved:
- Adding a lockable internal door between the front and rear sections ($2,000)
- Installing a basic kitchenette in the rear living area — benchtop, sink, cooktop, bar fridge space ($5,500)
- Cosmetic refresh of the rear section — paint, floating floors ($4,500)

Total cost: $12,000. No structural walls were moved. No new plumbing was required beyond a single sink connection. Under Victorian building regulations, works under $10,000 per trade do not require a building permit, and we structured the works across separate trades (cabinetry, plumbing, painting) to remain compliant.

The front section — three bedrooms, one bathroom, kitchen, and front living area — rented for $380 per week to a young family. The rear section — one bedroom, one bathroom, kitchenette, and rear living area — rented for $150 per week to a single tenant.

Combined main house rent: $530 per week.

## The full picture: $900/week on a $930K total investment

Total weekly rental income:
- Front section of main house: $380
- Rear section of main house: $150
- Granny flat: $370
- **Total: $900 per week**

Total investment:
- Purchase price: $800,000
- Stamp duty: ~$44,000
- Granny flat: ~$121,000 (incl. GST + permits)
- Main house reconfiguration: $12,000
- **Total: ~$977,000**

Gross yield: ($900 x 52) / $977,000 = **4.8%**

But here is where it gets interesting. The bank valuation after completion came in at approximately $1,050,000 — reflecting the granny flat's contribution to the property's assessed value. On a refinance at 80% LVR, that releases approximately $63,000 in equity above the original loan amount. That is more than half the granny flat construction cost returned as tax-free cash.

And we have not even discussed the subdivision potential. This corner block, with its dual street frontage, is a candidate for a future two-lot subdivision. The rear lot — with the granny flat already constructed on it — could be sold independently for $350,000-$400,000 once subdivision approval is obtained. The front lot with the existing house retains a value of $600,000-$650,000.

Combined post-subdivision value: $950,000-$1,050,000 plus the $130,000 in rental income collected during the hold period. On a total outlay under $1 million, that is a textbook example of manufactured wealth.

Corner blocks are not just properties. They are platforms for financial engineering. And in Melbourne's southeast, they are still available in the $750,000-$850,000 range if you know where to look.

## Frequently asked questions

**How do I find corner blocks in Melbourne's southeast?**
Most are not labelled as corner blocks in online listings. Our team identifies them through map analysis during our screening process. We check every property's lot configuration against aerial imagery before recommending it to clients.

**Is the one-into-two reconfiguration legal?**
Yes. Under Victorian regulations, a single title can accommodate up to three separate leases without triggering rooming house registration, provided each tenancy has independent living facilities. Our configuration creates two distinct spaces within the existing building envelope.

**What if I cannot afford the granny flat construction upfront?**
You can apply for a construction loan (side loan) once the property has settled and you have building permits and a fixed-price contract. The bank assesses the property on an 'as-if-built' basis, meaning the construction loan is secured against the future improved value.
