Cash Is Melting. Here's How Property Investors Become the Winners.

Let me give you a thought experiment that changed how I think about money.

Imagine there are 50 apples in the world and 50 dollars. Each apple costs one dollar. Simple.

Now the government prints another 50 dollars. There are still only 50 apples. But suddenly each apple costs two dollars. Your dollar didn't change — but it now buys half as much.

That's not a metaphor. That's literally what's happening. Global M2 money supply — the total amount of money sloshing around the world's economies — crossed $100 trillion in 2022 1. In 2000, it was about $25 trillion. We've quadrupled the money supply in two decades. The number of houses in Melbourne's established suburbs has not quadrupled.

This is the single most important thing to understand about property investment: inflation is not a bug in the system. It's a feature. And the people who borrow against hard assets before prices rise are the ones who build generational wealth.

Why your savings account is a wealth destruction machine

Let's do the maths that your bank doesn't want you to think about.

A high-interest savings account in Australia pays roughly 3-4% as of 2022 2. The Consumer Price Index — the official measure of inflation — is running at 5.1% 3. That means your real return (after inflation) is negative. Your $100,000 in savings loses approximately $1,100 to $2,100 in purchasing power every year.

But it's actually worse than that. The CPI measures a basket of consumer goods. Property prices, education costs, healthcare — the things that actually determine your quality of life — are inflating at 6-10% annually. Your savings account isn't treading water. It's drowning.

"Cash is not king," Robert Kiyosaki wrote in Rich Dad Poor Dad. "Cash is trash." That's provocative, but the data supports it. The Australian dollar has lost roughly 85% of its purchasing power since 1970 4. A house that cost $18,000 in 1970 now costs $900,000. The house didn't change. The money did.

So what do you do? You stop saving and start borrowing. Specifically, you borrow long-term against assets that inflate faster than the cost of the debt.

Good debt vs bad debt: the distinction that creates millionaires

A car loan at 8% on a depreciating asset is bad debt. You're paying interest on something that loses value every day. By year three, you owe more than the car is worth. That's financial suicide in slow motion.

A 30-year mortgage at 4.5% on a Melbourne house that appreciates at 7% per year is good debt. The asset grows faster than the cost of carrying it. And — here's the part that makes property people grin — the debt itself is being eroded by inflation.

Think about it. You borrow $560,000 today to buy a $700,000 house (80% LVR). Your monthly repayments are fixed in nominal dollars. But over 10 years, inflation shrinks the real value of those repayments. What feels like $3,200/month today will feel like $2,400/month in 2032 dollars, because your wages have risen with inflation even if your repayment hasn't 5.

Meanwhile, the house has grown from $700,000 to approximately $1,377,000 (at 7% compound growth). Your $560,000 debt hasn't changed. You've gained $677,000 in equity while inflation did the heavy lifting.

"Every dollar you borrow at 4.5% and invest in an asset growing at 7% creates a 2.5% annual arbitrage," says Joey Don, Co-Founder of PremiumRea. "On a $560,000 loan, that's $14,000 a year in wealth creation. For doing nothing except making your repayments."

The two-property retirement blueprint

I'm going to lay out the simplest wealth-building model I know. It requires no financial genius, no stock-picking skill, and no lucky timing. It just requires patience and two properties.

Buy two houses at $700,000 each in Melbourne's southeast corridor. Total outlay: approximately $350,000-$400,000 including deposits, stamp duty, and renovation costs. The rest is borrowed 6.

Hold for 30 years.

At 7% annual compound growth — which is conservative based on Melbourne's 30-year median house price trajectory — each property grows to approximately $5.33 million. Two properties: $10.66 million. Even adjusted for inflation at 3%, the real value is roughly $5.5 million in today's dollars.

A 4% rental yield on $10.66 million is $426,000 per year in passive income. For a couple, that's $213,000 each. Inflation-adjusted? Still roughly $220,000 per year in today's money.

Compare that to the average Australian superannuation balance at retirement: $292,500 for men, $138,000 for women 7. A $300,000 super balance draws down at roughly $20,000 per year under the 4% rule. It runs out at age 82.

Two properties, bought at 35, held until 65, generating $220,000 per year forever. Versus $300,000 in super, generating $20,000 per year for 17 years. The maths isn't even close.

And here's the best part: during the 30-year hold, the rental income covers the mortgages. You're not actually paying for these properties. Your tenants are. Your total out-of-pocket contribution over three decades is that initial $350,000-$400,000.

What banks actually care about (and how to use that knowledge)

Banks are in the business of lending money against assets that hold value. When they assess your property for a mortgage, they care about three things above all else 8:

1. Rental income relative to the loan. A property generating $800/week against a $600,000 loan is a much safer bet (for the bank) than one generating $400/week against the same loan. Higher rent = higher serviceability = higher approval probability.

2. Vacancy risk. A property in a suburb with 1.2% vacancy is nearly risk-free from the bank's perspective. One in a suburb with 5% vacancy raises questions about whether the income stream is reliable.

3. Depreciation schedule. The tax deductions from building depreciation and plant & equipment reduce your net expenses, which improves your borrowing capacity on the next property.

This is why we buy properties that can be improved — a cosmetic renovation plus a granny flat turns a $420/week rental into a $900/week rental, which transforms your borrowing capacity for the next purchase. The bank sees a self-funding asset with strong income, low vacancy, and generous depreciation. They want to lend you more money. That's the cycle that creates wealth.

Inflation is the tailwind. Property is the vehicle. Leverage is the accelerator. And rental income is the fuel that keeps the whole machine running without your intervention.

Stop saving. Start borrowing against assets that grow faster than the interest rate. That's the whole game.
