This One Cranbourne House Made Me $300K. Here's Exactly How.

I'm going to show you my first investment property in Melbourne. Not a client's — mine. My own money on the line.

The suburb is Cranbourne, about 45 kilometres southeast of the CBD. When I bought in early 2023, Melbourne was at its absolute lowest point. Listings were sitting for weeks without a single offer. Half the buyer's agents I know were telling their clients to wait. The media was running doom headlines about Victorian property every second Tuesday.

I went the other direction. Our team had already been tracking southeast Melbourne data for 18 months, and everything pointed to a recovery window. Population inflows into the far southeast were running at 3.2% annually. Rental vacancy in Cranbourne had dropped below 1.5%. And crucially, there was almost zero new land release within the established suburb — unlike the greenfield disaster zones out west where every month brings another 200 house-and-land packages onto the market.

So I bought. A beaten-up weatherboard on a 650-square-metre block, guide price $750K. I got it for just over $700K using an unconditional offer — no finance clause, no building inspection clause. The vendor's agent practically hugged me. In that market, certainty was worth more than price.

What the property looked like on day one

Honestly? A mess. The kitchen was original 1970s laminate. Carpet was stained beyond professional cleaning. The bathroom had a slow leak under the vanity that had warped the subfloor. External paint was peeling on the north face.

But the bones were solid — single-brick veneer on a timber frame, no structural cracks, no termite history in the building report. The land was flat with a 3.2-metre side driveway (that number matters enormously — it means a crane truck can access the backyard for future construction). And the block shape was rectangular with no easement running through the middle.

In our buying framework, this ticked every box. Land value represented roughly 85% of the purchase price. The building was depreciating at 2.5% a year, but the land under it was sitting in a supply-constrained corridor with genuine population demand. That's the formula we repeat for every client: buy the land, get the house free.

The $80K renovation that changed everything

I spent $80,000 on this place. That sounds like a lot until you see what it produced.

Before settlement even completed, I had our team start the paperwork for a building permit. Under Victorian regulations, internal modifications that don't change the building's external footprint don't require council planning approval — you just need a building permit from a registered building surveyor 1. That saved us roughly 12 weeks of waiting.

The renovation scope:

• Internal partition walls to create three separate living zones (tri-living configuration)
• Three independent kitchen setups (each with cooktop, sink, small fridge space)
• Upgraded electrical to separate metering for each zone
• New flooring throughout — SPC vinyl plank, which runs about $35 per square metre installed and handles rental wear far better than carpet
• Full bathroom refresh (not gut — refresh: new vanity, new tapware, reseal shower, replace toilet seats)
• External repaint on the worst two faces
• New front fence

The tri-living setup is the key move here. Instead of renting the house as a single dwelling for maybe $550 a week, I created three separately rentable spaces — each with its own entrance, kitchen, and living area. Under Victorian tenancy law, a single title can have up to three separate leases without triggering rooming house registration requirements, as long as each space is self-contained 2.

Total cost including the renovation: $780,000. That becomes the number I measure everything against.

The rent: $1,200 a week from a $780K total outlay

Here's where the maths gets interesting.

Three tenants, three leases. Combined weekly rent: close to $1,200. That's a gross yield of 8% on total cost — in a market where the Melbourne average sits around 3.2% 3.

Let me break that down further. My initial cash outlay was roughly $220,000 — that's the 20% deposit on $700K ($140,000) plus $80,000 renovation costs. In the first full year of operation, after deducting mortgage interest at 6.2%, council rates, water charges, insurance, land tax, and property management fees, I was left with positive cash flow of about $12,000.

Positive cash flow. In the first year. During the highest interest rate environment since 2008.

Most investors I talk to are bleeding $5,000-$15,000 a year on their Melbourne holdings right now because they're running single-tenancy whole-house rentals at 3% yield. I'm not criticising that strategy — negative gearing works brilliantly for high-income earners chasing capital growth. But if you want the asset to feed itself from day one, you need to think about how the internal configuration generates rental income, not just the sticker price.

"We've now done this conversion for over 30 clients in the far southeast. The pattern holds: $65K-$80K renovation spend, rental uplift of 50-80% versus whole-house leasing, and the property typically revalues $100K-$150K higher within six months of completion." — Joey Don

Capital growth: $700K to $930K in under three years

Two and a half years after purchase, I requested a desktop valuation from CBA. The result: $930,000.

That's a $230,000 increase on the purchase price — a 33% gain. On my actual cash invested ($220,000), it represents a return of over 100%.

Now, I can't take full credit. Part of that growth is market-driven — Cranbourne house values have been climbing at around $5,000 per month since mid-2023, driven by the same supply-demand dynamics I identified before buying 4. But a meaningful chunk of the revaluation comes from the physical improvements and the proven rental income stream. Banks value income-producing properties higher than equivalent vacant or single-tenancy properties.

The practical implication: I can now refinance at 80% of $930,000 ($744,000), pay out my existing loan of approximately $560,000, and extract roughly $180,000 in tax-free equity. That's enough for a 20% deposit on two more properties in the $700K range. This is what we call asset multiplication — using equity release to fund the next purchase without saving another cent from your salary 5.

I haven't done the refinance yet because I'm timing it against a couple of other moves. But the option is sitting there, ready to deploy.

Why Cranbourne specifically

People ask me this all the time. Melbourne has 300-odd suburbs — why Cranbourne?

Four reasons.

First, affordability. The median house price in Cranbourne was around $620,000 when I bought. That's right in the sweet spot for the largest buyer demographic in Australia — young families earning $120,000-$140,000 combined household income, borrowing at 5-6 times earnings 6. When your target suburb matches the affordability band of the largest buyer pool, demand is structurally embedded.

Second, land supply constraint. Unlike the disaster zones of Point Cook, Tarneit, and Clyde North — where thousands of new house-and-land packages hit the market every year — established Cranbourne has no greenfield release. Every block is already built on. When you buy land here, you're buying a finite resource.

Third, infrastructure. Cranbourne has a train station, a major hospital within 15 minutes, multiple shopping centres, and sits at the junction of two arterial roads. It's not glamorous infrastructure, but it's functional infrastructure that supports rental demand. We specifically target suburbs where you could live a normal suburban life without a car if you had to — that's a proxy for rental resilience.

Fourth, development upside. My block at 650 square metres with a 3.2-metre driveway qualifies for future subdivision under council guidelines. Comparable subdivisions in the area — keeping the front house and building a new dwelling behind — have produced net profits of $150,000-$200,000 7. That's a future optionality I haven't even touched yet.

"Cranbourne in 2023 was what Frankston was in 2018 — underpriced relative to fundamentals, with a negative media narrative keeping buyers away. We bought 11 properties there in a six-month window. Every single one has appreciated." — Joey Don

The annual return calculation

Let me show the full picture on this one asset.

Cash invested: $220,000 (deposit + renovation) Current valuation: $930,000 Capital gain: $230,000 Annual cash flow (year 1): +$12,000 Annual cash flow (projected year 3, with rent increases): +$18,000

Total return over 2.5 years: approximately $260,000 (capital gain + cumulative cash flow).

Annualised return on cash invested: roughly 25%.

For context, the ASX 200 returned about 8% per annum over the same period. A term deposit at 4.5% on $220,000 would have generated $24,750 over 2.5 years. My property generated ten times that.

And that's before the tax benefits. The $80,000 renovation creates a depreciation schedule — the building surveyor's quantity report allows me to claim approximately $3,500 per year in non-cash deductions against rental income, which at my marginal tax rate translates to a $1,500 annual tax refund 8. Small money relative to the capital gain, but it adds up.

I studied at one of the top-ranked business schools globally. I've modelled asset returns across equities, bonds, commodities, and real estate. And I can tell you with complete conviction: a well-selected Melbourne investment property with a value-add renovation strategy produces risk-adjusted returns that are exceptionally hard to replicate in any other asset class accessible to retail investors.

What I'd do differently

Transparency matters, so here's what I got wrong.

I underestimated the time to get the building permit processed. I budgeted four weeks; it took seven. The building surveyor flagged a drainage issue with my proposed kitchen configuration, and resolving it cost an extra $2,200 and three weeks of back-and-forth. If I'd engaged the surveyor before settlement (with the vendor's permission to access the property — which is possible on longer settlement terms), I could have shaved a month off the vacancy period. At $1,200 per week in lost rent, that month cost me $4,800.

I also should have negotiated harder on the purchase price. In that dead market, I probably left $10,000-$15,000 on the table. I was so excited about the block dimensions and the tri-living potential that I moved faster than I needed to. As a buyer's agent, I tell my clients to never fall in love with a property before you own it. I broke my own rule.

And the renovation budget blew out by about $8,000 — mostly because I upgraded the electrical work from the minimum spec to a higher standard with separate sub-boards for each living zone. That was the right long-term decision (it makes future separately-metered billing possible), but I should have scoped it from the start instead of treating it as a variation midway through.

Can you replicate this?

Yes. With caveats.

The core strategy — buy an undervalued house on good land, convert the interior to multi-tenancy, hold for capital growth — works in any southeast Melbourne suburb where the numbers stack up. We've done versions of it in Hampton Park, Narre Warren, Frankston, and Boronia. The rental uplift from tri-living conversions is remarkably consistent: 50-80% above whole-house rates.

But execution matters enormously. Picking the wrong block (too steep, easement through the middle, double-brick construction that makes renovation prohibitively expensive) can turn a $230K profit into a $30K loss. The renovation itself needs to be scoped by someone who understands tenancy law, building regulations, and rental market dynamics simultaneously. A standard builder won't think about separate entrances or kitchen placements that maximise rental appeal. A standard property manager won't think about which rooms convert to self-contained studios most cost-effectively.

The honest truth is that this strategy requires either significant personal expertise or a team that operates across buying, renovating, and leasing. That's what we built our business around — not because it's a nice marketing story, but because the financial outcomes are dramatically better when all three functions talk to each other from day one.

If you're sitting on $200,000-$250,000 in savings or accessible equity and you want an asset that pays for itself immediately while growing at 8-10% per annum, this is the playbook. Melbourne's far southeast still has pockets where $650,000-$750,000 buys you a 600-plus square metre block with tri-living potential. Those pockets won't exist at that price point forever — we're already seeing $5,000 monthly price creep in our core suburbs 4.

"The mistake most investors make is treating buying and renting as separate decisions. They buy for growth, then hand it to a property manager who does the bare minimum. We design the rental outcome before we even put in an offer." — Joey Don
