For many Australians, this is the big financial dilemma:
Should I pay off my mortgage faster, or use my equity to invest in property?
It’s a question we hear every day—and the answer depends on your goals, risk tolerance, financial position, and the current market landscape.
In 2025, with interest rates stabilising and property values on the rise again in key areas, more homeowners are sitting on substantial equity. The temptation to “do something smart with it” is stronger than ever.
So what’s the right move? Let’s break down both options using real numbers, real strategies, and a clear-eyed look at opportunity cost, equity utilisation, and risk management—all in an Australian context.
First: Let’s Define the Two Options
Option 1: Pay Off Your Mortgage Faster
This means using any surplus cash (salary, tax refund, bonuses, etc.) to make additional repayments on your home loan—reducing your debt and saving on interest over time.
Option 2: Use Equity to Invest in Property
Rather than reducing your loan balance, you access the equity in your current home to fund the deposit on an investment property—while continuing to service your existing loan.
Understanding the Trade-Off: Safety vs Growth
At its core, the decision comes down to this:
- Paying off your mortgage = certainty and security
- Investing = higher potential returns but more risk
Neither is “wrong”—but they have very different outcomes over time.
Let’s Talk Equity: The Hidden Asset Most Aussies Don’t Use
What is Equity?
Equity is the difference between your home’s value and the amount you still owe on your mortgage.
Example:
- Home value: $850,000
- Loan balance: $450,000
- Total equity: $400,000
- Usable equity: Around $230,000 (after keeping 20% buffer)
This equity can be used to:
- Fund an investment property deposit
- Cover purchasing costs
- Create long-term wealth through capital growth and rental income
If you’re only focusing on paying off your home loan, this money sits idle—earning you nothing.
Opportunity Cost: What Are You Missing by Paying Down the Mortgage?
Paying extra on your mortgage saves you interest.
That’s a guaranteed return—currently around 5.5–6% p.a. in 2025 based on standard variable rates.
But…
Investing in property can earn you more over time.
Let’s say you use $150,000 in equity to invest in a $600,000 property:
- Rental yield = 4.5% = $27,000 p.a.
- Annual growth (conservative) = 5% = $30,000 p.a.
- Total return = ~$57,000 on $150,000 equity = 38% ROI
Even accounting for holding costs and tax, the long-term upside often outweighs the mortgage interest savings—especially when leveraging through real estate.
This is what financial experts call opportunity cost: the cost of choosing one option over another, potentially higher-returning one.
How to Calculate What’s Best for You (Real Example)
Scenario 1: Pay $20,000 Extra into Your Mortgage
- Mortgage interest saved = ~6% x $20,000 = $1,200 per year
- Over 10 years = ~$12,000 interest saved
Scenario 2: Use $20,000 (plus equity) as deposit for a $500,000 investment property
- Rental income = $450/week = $23,400 p.a.
- Mortgage + expenses = ~$28,000 p.a.
- Negative cash flow (claimable at tax time) = ~$4,600 p.a.
- Property growth (5%) = $25,000 in Year 1
Over 10 years, even moderate growth + tax benefits + rental yield can return 5–10x what you’d save paying off the mortgage.
When Paying Off Your Mortgage Might Be the Better Option
It’s not always about growth. Sometimes security and peace of mind matter more.
Consider focusing on mortgage reduction if you:
- Have high-risk aversion or are nearing retirement
- Expect job or income instability
- Want to be debt-free ASAP for emotional or lifestyle reasons
- Don’t have the time or appetite to manage an investment
Also: If you’re not in a strong enough financial position to handle the extra debt, investing can overextend you.
In these cases, eliminating personal debt first can be a powerful move.
When Investing Makes More Sense
You might be better off investing if you:
- Have at least 20% equity and stable income
- Can comfortably service both loans (PPOR + investment)
- Have a long-term investment horizon (10+ years)
- Want to build passive income or grow a portfolio
- Are confident with rental markets, property selection, and holding strategies
In 2025, leveraging equity while interest rates remain stable can be a powerful way to outpace inflation and secure future financial freedom.
Hybrid Approach: Can You Do Both?
Absolutely.
You can:
- Use your equity to invest, while…
- Making extra repayments into an offset account
This gives you flexibility. An offset account:
- Reduces interest payable on your home loan
- Keeps your savings accessible if needed
- Doesn’t lock your cash in, unlike redraw facilities
This way, you’re still reducing debt impact—without giving up the option to invest or access funds later.
Managing Risk: What If Rates Rise Again?
It’s a valid concern in a post-2022 rate-hike environment. But in 2025, the RBA has signalled a plateau—and some economists forecast cuts.
Still, good investors plan for the worst.
Here’s how to manage risk if you choose to invest:
- Stress test repayments at 1–2% above current rates
- Maintain a buffer of 3–6 months’ worth of expenses
- Choose a property with strong rental demand
- Avoid speculative growth suburbs or high-maintenance properties
- Work with a broker to structure the loan smartly (e.g. interest-only on the investment, principal + interest on your home)
Tax Implications: Another Key Factor
Paying Off Your Mortgage
- Reduces personal (non-deductible) debt
- Saves you interest, but offers no tax benefit
Investing in Property
- Interest on your investment loan is usually tax-deductible
- You can claim depreciation, management fees, maintenance, and more
- If the property is negatively geared, it can reduce your taxable income
Important: Always seek tax advice before making major financial moves.
What the Experts Say (2025 Market View)
According to CoreLogic and REA data:
- Equity-rich homeowners are the fastest-growing segment of new investors in 2025
- Most are using existing home equity, not savings, to buy
- In strong markets, property returns continue to outperform mortgage savings
That said, the best outcomes come from a well-structured plan—not impulse decisions.
Psychological Factors: Debt-Free vs Wealth-Building
For some, becoming mortgage-free brings peace of mind and a feeling of security. For others, leaving “lazy equity” untouched feels like a missed opportunity.
Ask yourself:
- Would I feel better owning one home outright in 15 years?
- Or owning three properties, all growing in value and generating income—even with debt?
Neither answer is wrong. It depends on what matters more to you: certainty or growth.
A Note on First Home Buyers and Young Homeowners
Even if you’ve just bought your first home, this question still matters.
As property prices rise and you build equity, you may face this decision within just 3–5 years of your first purchase.
Using your first home as a stepping stone to invest is one of the most common pathways to wealth for younger Australians in 2025.
Final Thoughts: So, Pay Off the Mortgage or Invest?
Here’s the recap:
If security is your priority, paying off your home is never a bad idea.
If growth is your goal, investing using equity is likely to deliver better outcomes—as long as you plan properly.
