Not All Debt Is Bad. Here Is How to Tell the Difference.

Not All Debt Is Bad. Here Is How to Tell the Difference. 

‍

‍

Most Australians are taught that debt is something to avoid. Pay it off as fast as possible. Live within your means. That mindset works for consumer spending. It is one of the most limiting beliefs an investor can carry.

The reality is that not all debt is created equal. Understanding the difference between debt that builds wealth and debt that destroys it is one of the most important financial distinctions you can make. For property investors specifically, it is the difference between a portfolio that compounds and a lifestyle that consumes. 

‍

The Two Types of Debt

At its most basic level, debt falls into two categories.

Good debt is borrowed money that works for you. It is used to acquire assets that grow in value, generate income, or increase your earning capacity over time. The cost of borrowing is justified by the return the asset produces.

Bad debt is borrowed money that works against you. It is used to fund consumption, lifestyle, or depreciating assets. The interest compounds while the thing you bought delivers no financial return.

What Good Debt Looks Like for Property Investors

For Australian property investors, the most powerful example of good debt is an investment loan secured against a residential property.

Here is why it works so well:

When you borrow to buy an investment property, you are using the bank's money to control an asset worth many times your deposit. A 10% deposit on a $700,000 property means you control a $700,000 asset with $70,000 of your own capital. If that property grows by 7% in a year, the $49,000 in value created represents a 70% return on your actual cash outlay.

That is the power of leverage applied to a productive asset. You are not just earning a return on your own money. You are earning a return on the bank's money too.

On top of that, the interest you pay on an investment loan is tax deductible. The asset generates rental income. The depreciation reduces your taxable income further. The debt is not costing you what it appears to cost on paper once the tax benefits are factored in.

Mortgage debt used strategically to acquire growth assets is not a liability to minimise. It is a tool to deploy intelligently.

‍

What Bad Debt Looks Like

Bad debt operates in the opposite direction. The interest compounds, the asset depreciates or delivers no return, and your net worth moves backwards even as you make repayments.

‍

The most common examples:

1. Credit card debt carries interest rates of 18% to 22% per year in Australia. Carrying a balance on a credit card is one of the fastest ways to destroy wealth. The interest rate almost always exceeds any investment return available, which means every dollar sitting on a credit card is losing ground every month.

2. Personal loans for lifestyle spending (holidays, clothing, entertainment) fund consumption that delivers no financial return. The moment the holiday ends, the debt remains. The asset, if you can call it that, is gone.

3. Car loans on depreciating vehicles sit in a grey area. A reliable vehicle may be necessary for work and income. A luxury vehicle financed beyond your means, with payments that restrict your ability to invest, is bad debt regardless of how it is rationalised.

The test is straightforward: is the thing you are borrowing for going to be worth more in five years or less? Is it generating income or consuming it? If the answer points to depreciation and consumption, it is bad debt.

Common Mistakes Investors Make With Debt

Understanding the difference between good and bad debt is one thing. Applying it consistently is another. These are the errors that cost investors the most.

Paying down investment debt instead of consumer debt

• A $400,000 investment loan at 6% and a $15,000 credit card at 20% are not equal problems. The credit card is costing more than three times the interest rate. Eliminate high-interest consumer debt first, always, then redirect that freed-up cash flow toward your investment position.

Using equity for lifestyle spending

• Equity accessed for holidays, renovations on the family home, or discretionary purchases converts good debt into bad debt. You are carrying a larger loan and the money spent is delivering no financial return. Equity is most powerful when redeployed into further productive assets.

Not maintaining buffers

• Investors who get into trouble with debt are rarely the ones who borrowed too much. They are the ones who borrowed without the cash reserves to hold through a difficult period. Three to six months of cash set aside is sensible. A cash buffer is what keeps good debt from becoming a problem.

Treating all investment loans the same

• The debt does not determine whether the investment is sound. The asset behind it does. Leverage amplifies the outcome of the underlying asset, positive or negative. Getting the asset selection right matters as much as getting the loan structure right.

How This Changes the Way You Think About Investing

Investors who understand the good debt versus bad debt distinction approach their finances very differently to those who treat all debt as something to avoid.

They prioritise eliminating bad debt, credit cards, personal loans, consumer finance, as quickly as possible. They do this not because debt itself is the enemy, but because bad debt actively erodes the capital available to deploy into productive assets.

They use good debt deliberately and strategically. They structure investment loans to maximise tax efficiency. They understand that borrowing at 6% to acquire an asset growing at 8 to 10% per year is a rational, wealth-building decision, not a financial risk.

They also maintain buffers. Emergency funds that prevent a short-term cash flow problem from forcing a sale. Serviceability headroom that allows them to hold through rate rises without being forced out of the market. The buffer is what allows good debt to remain good through difficult periods.

The Mindset Shift That Changes Everything

Australians who build substantial property portfolios are not people who avoided debt. They are people who understand which debt to avoid and which to use.

The investors who remain stuck are often the ones paying down a low-interest investment loan as fast as possible while carrying consumer debt at three times the interest rate. Or the ones avoiding an investment loan entirely because debt feels uncomfortable, while the property market moves without them.

Debt is not the problem. Unproductive debt is the problem. Debt attached to a growing, income-producing asset is one of the most effective wealth-building tools available to everyday Australians. The key is knowing the difference and making decisions accordingly.
