Good Debt vs Bad Debt: How to Tell the Difference

Not all debt works the same way.

Some borrowing costs you money every month without giving anything back. Other debt generates income, reduces your tax, or builds assets that grow over time. The difference between the two shapes your financial position more than most people realise, and if you own property with equity sitting idle, the distinction matters even more.

What Makes Debt Good or Bad

Good debt pays for itself. It funds an asset that either earns income or increases in value, and the interest is often tax deductible. Bad debt funds lifestyle expenses or depreciating assets, the interest isn't deductible, and you're left with nothing that generates a return.

Your home loan is typically non-deductible debt. You're paying it down with after-tax income, and while your property might grow in value, the loan itself doesn't reduce your taxable income. An investment loan, on the other hand, funds an income-producing asset. The interest is deductible, and the property could appreciate while generating rent. That's the clearest example of good debt at work.

In areas like Kew East, where established homes on larger blocks appeal to both owner-occupiers and investors, many homeowners are sitting on significant equity but still carrying a non-deductible mortgage. The opportunity isn't always obvious until you start thinking about how that equity could be redeployed.

How Debt Recycling Converts One Into the Other

Debt recycling is a strategy that gradually converts non-deductible home loan debt into tax-deductible investment debt. You borrow against your home equity, invest the funds in income-producing assets like shares or property, and use the income plus your tax refund to pay down your home loan faster. Over time, more of your total debt becomes deductible.

Consider a homeowner in Kew East with a mortgage balance sitting around 40% of their property's value. They've built up equity, but they're still paying down their home loan with after-tax dollars. Through debt recycling, they could access that equity, invest it in a diversified portfolio or an investment property, and claim the interest as a deduction each year. The investment income, combined with the tax benefit, accelerates the repayment of the non-deductible home loan. What was once entirely bad debt starts shifting toward good debt.

The structure matters. You'll typically split your loan so the investment portion remains separate and clearly documented. That separation keeps your records clean for the ATO and ensures you're only claiming what's genuinely deductible. It's not a loophole. It's a recognised strategy, but it relies on accurate setup and ongoing compliance.

The Risks That Come With Leverage

Borrowing to invest amplifies both gains and losses. If your investment performs well, the returns can outpace the interest cost and deliver a meaningful outcome. If it underperforms, you're still servicing the debt without the income or growth to justify it.

Cashflow is the other pressure point. You're adding a new loan repayment to your existing commitments, and while the tax deduction helps, it doesn't arrive until you lodge your return. In the meantime, you need enough income to cover both loans comfortably. If your employment changes or interest rates rise, that buffer can disappear quickly.

Debt recycling works when your income is stable, your risk tolerance is appropriate, and your investment horizon is long enough to ride out volatility. It's not a strategy to rush into during uncertain employment or when your cashflow is already stretched. A conversation with both a broker and a financial planner is the right starting point, not an afterthought.

When Good Debt Stops Being Good

Debt is only good if the asset it funds continues to perform. If you borrow to buy an investment property and it sits vacant for months, or the capital growth stalls while rates climb, the interest deduction doesn't compensate for the financial drain. The same applies to borrowing for shares that decline in value or fail to deliver the expected dividends.

Over-leveraging is the other trap. Just because you can access equity doesn't mean you should deploy all of it. Lenders will assess your borrowing capacity, but they won't assess whether the strategy aligns with your broader financial goals or your ability to manage a downturn. That's your responsibility, ideally with professional input.

In practice, good debt only stays good if it's managed actively. That means monitoring performance, maintaining adequate cash reserves, and being willing to adjust the strategy if circumstances change. It's not a set-and-forget approach.

Kew East Property Owners and Equity Positioning

Kew East sits within Boroondara, an area where property values have historically been strong and ownership tenure tends to be longer. Many homeowners in the suburb have built substantial equity without necessarily having a plan for it. That equity can fund renovations, help with upgrading to a larger home, or be deployed through a debt recycling structure to build wealth outside the family home.

The leafy streets, proximity to quality schools like Bellevue Primary and Carey Grammar, and access to both Kew Junction and the Eastern Freeway make the area appealing to families who plan to stay. That stability creates the right conditions for longer-term financial strategies, including those that involve leverage. If your home loan is relatively small compared to your property value, and your income can support additional borrowing, the question becomes whether you're using that equity intentionally or just leaving it idle.

A mortgage broker in Kew East can model the numbers, structure the split loan correctly, and connect you with financial planners who specialise in debt recycling. The strategy isn't appropriate for everyone, but it's worth understanding whether it fits your situation before deciding to ignore it.
