We each built a $3.5M+ property portfolio before 30.
Here are the 8 principles we share, but no one talks about.
We're three Australian engineers. All raised here. All built our property portfolios independently, on different sides of the country, without comparing notes.
We're different ages. But each of us hit the same milestone at roughly the same life stage: $3.5M+ by 30, tracking to $7M by 40.
We met on social media. When we finally sat down to compare notes, what we found was surprising — the paths we'd walked were nearly identical, and the principles we'd each arrived at independently were essentially the same eight ideas.
If any one of these doesn't make sense to you yet — we'd suggest you don't buy yet. Your hard-earned money deserves better than a half-formed plan.
The 8 Principles
The ideas we each arrived at independently — and now use on every property we buy.
You're buying an investment, not a home.
Whether you like the property has nothing to do with whether it's a good investment.
What you don't like doesn't mean there isn't a market. There's plenty of food we don't eat — the restaurants serving it are still full. Property works the same way. The people you wouldn't rent to are someone's tenants. The facade you'd never choose is someone else's dream home.
Gut reactions about kitchens, facades and "feel" are noise. The numbers are the signal.
You're not buying a house. You're buying land with a house on it.
Land is the scarce asset. Buildings are consumable — they age, depreciate, need replacing. Land doesn't.
Our rule: no land component, we don't buy. That disqualifies most off-the-plan apartments and high-density stock where you own a slice of air above a shared title.
Of all the strategies out there, 99% of investors should only run one.
The property content ecosystem is full of flavoured strategies — granny flats, subdivisions, SMSF, dual-occ, negative gearing. It sounds complex. It isn't.
There are really only two categories:
Buy well. Hold. Let compounding and leverage do the work across decades. Minimal ongoing effort after purchase.
Renovate, add granny flats, subdivide, develop. Requires trades, site selection, time, and risk tolerance most investors don't have.
Tax, lending and policy are tools. They're not strategies.
For salaried professionals, active strategies are usually a trap. Buy and hold is almost always the right answer.
Picking the right area is the most important decision you'll make.
It's like the foundation of a building.
Every other mistake has a recovery path — wrong colour scheme, overpaying by 3%, suboptimal loan structure. You can work around those.
Wrong location, wrong fundamentals? Only one fix: sell at a loss and start over.
Most buyers obsess over the kitchen benchtop and ignore the suburb's demographics. They're optimising the wrong variable that does not affect investment return.
The real advantage of property is cheap leverage.
If you're planning to buy investment property with low borrowing, we'd suggest you don't buy.
Leverage is the core mechanic of property. A bank will lend you 80% of the purchase price at the cheapest rate you'll ever access for any asset, secured against the property itself.
If debt isn't for you, shares and ETFs are better homes for your capital. Property without leverage is a mediocre asset.
Capital growth vs. rental yield is a false choice for almost everyone.
It's not a real question. The balancing act only matters once you own five or more properties, when cash flow starts constraining borrowing capacity.
Fewer than 0.1% of Australians own five or more investment properties.
If you're buying your first or second, stop trying to optimise a problem you don't have yet. Pick a high-quality growth market with reasonable yield and move on.
Accept that the market will always have opposing voices.
Most property media and content creators have a business model that depends on your attention, not on your return.
When you read a hot take, ask one question: does this view benefit the creator's business?
We're not saying ignore them. We're saying hold the content against its incentive structure before you internalise it. If the view benefits their business, put a big question mark on it.
Buy nationally. Don't limit yourself to suburbs you already know.
Australia has roughly 15,000 suburbs. A well-informed local knows maybe 50. That's 0.3% of the market — meaning 99.7% is a blind spot, even for engaged buyers.
The best-performing markets in any given window are rarely the ones you grew up near. Limiting your search to familiar suburbs isn't comfort — it's a constraint you're placing on your own returns.
Instead of asking that question, we asked ourselves these three.
- Do you have confidence in the Australian economy over the next 10–20 years?
- Do you believe Australia will build housing faster than population growth anytime soon?
- Do you understand the realistic returns and risks — and do you still want to proceed?
If you answered yes to all three, the timing question answers itself.
