How to Use Equity in Your Australian Property to Buy an Investment Property in 2026

Property investment remains one of the most effective wealth-building strategies in Australia. For many homeowners, the equity accumulated in their primary residence can serve as a powerful financial tool to expand their portfolio. This comprehensive guide will walk you through the process of leveraging your home equity to purchase an investment property in 2026, covering everything from calculations and lender policies to tax considerations.


Understanding Home Equity

Home equity is the difference between the current market value of your property and the amount you still owe on your mortgage. For example, if your home is worth $800,000 and your remaining loan balance is $400,000, your equity is $400,000. This equity can be used as security for a new loan, allowing you to borrow against it to fund an investment property purchase.

In 2026, Australian property values have continued to grow in many regions, though at a moderated pace compared to the post-pandemic boom. According to the Australian Bureau of Statistics, residential property prices rose by 4.5% nationally over the 2025 calendar year, with stronger growth in capital cities like Brisbane and Perth (ABS Residential Property Price Indexes). This growth has increased equity for many homeowners, making it an opportune time to consider leveraging it.

Usable Equity vs. Total Equity

Lenders typically don’t allow you to borrow against 100% of your equity. They generally permit borrowing up to 80% of the property’s value (loan-to-value ratio or LVR) without incurring lender’s mortgage insurance (LMI). Some lenders may go higher, but LMI can add significant costs.

To calculate usable equity, use this formula:

Usable Equity = (Property Value × 0.80) – Current Loan Balance

For our example:

• Property value: $800,000
• 80% LVR: $640,000
• Current loan: $400,000
• Usable equity: $240,000

This $240,000 can be used as a deposit for an investment property, potentially covering the full 20% deposit and purchase costs for a property worth up to around $1,000,000, depending on lender requirements.

Step-by-Step Guide to Using Equity

Step 1: Determine Your Property’s Current Value

Before approaching a lender, you need an accurate valuation of your home. You can:

• Obtain a free online estimate from property data platforms, but these can be inaccurate.
• Hire an independent valuer (cost: $300–$600).
• Ask your lender for a valuation, often free if you’re applying for a new loan.

In 2026, automated valuation models (AVMs) have improved, but a full valuation by a certified valuer is still recommended for equity release. The Australian Property Institute provides resources on finding qualified valuers (Australian Property Institute).

Step 2: Calculate Your Usable Equity

Use the formula above. Remember to factor in any existing mortgage and other debts secured against the property. Also, consider that lenders may have different LVR caps for investment loans (often 80%–90% with LMI).

Step 3: Understand Loan Structures

There are two main ways to access equity:

1. Loan Increase or Top-Up: You increase your existing home loan by the amount of equity you want to release. The funds are deposited into your account, and you then use them as a deposit for the investment property.
2. Separate Loan Split or Line of Credit: You create a new loan account or a line of credit secured against your home. This keeps the investment-related borrowing separate, which can be beneficial for tax purposes (discussed later).

Lenders may offer equity release loans with features like offset accounts or redraw facilities. As of 2026, many lenders have tightened their serviceability assessments, so ensure your income can support the additional debt.

Step 4: Assess Your Borrowing Capacity

Lenders will assess your ability to service both your existing home loan and the new investment loan. They consider:

• Your income (employment, rental, other)
• Living expenses
• Existing debts
• The proposed rental income from the investment property (usually at 75%–80% of market rent)
• Interest rate buffers (typically 3% above the actual rate)

Use online borrowing power calculators, but for a precise assessment, consult a mortgage broker or lender. The Australian Securities and Investments Commission’s MoneySmart website offers a useful budget planner (ASIC MoneySmart).

Step 5: Find the Right Investment Property

With your budget set, research high-growth areas. In 2026, regional centres and outer suburbs of major cities are showing strong rental demand due to infrastructure projects and population shifts. Consider factors like:

• Proximity to transport, schools, and amenities
• Vacancy rates (aim for below 3%)
• Historical capital growth
• Future development plans

Step 6: Apply for Finance

Submit a loan application with your chosen lender. You’ll need:

• Proof of income (payslips, tax returns)
• Details of assets and liabilities
• Property valuation report
• Identification documents

The lender will also value the investment property you intend to buy. If all checks pass, you’ll receive conditional approval, then formal approval after satisfying any conditions.

Step 7: Settlement and Beyond

Once the loan is approved and the property settles, you become a landlord. Manage the property yourself or hire a property manager. Ensure you have appropriate landlord insurance and understand your tax obligations.

Lender Policies and Considerations in 2026

Lending policies have evolved. In 2026, the Australian Prudential Regulation Authority (APRA) maintains a focus on responsible lending. Key points:

• Interest Rate Buffers: APRA requires lenders to assess new loans at 3 percentage points above the loan’s actual rate. With the cash rate at 3.85% in early 2026 (Reserve Bank of Australia), investment loan rates are around 6.5%–7%, meaning serviceability is tested at 9.5%–10%.
• Debt-to-Income (DTI) Ratios: Some lenders cap DTI at 6–7 times income for investment loans.
• Rental Income Recognition: Lenders typically use 75% of gross rental income to account for expenses, though some may use 80% if you have a strong rental history.
• Cross-Collateralisation: Avoid cross-collateralising your home and investment property with the same lender, as it can limit future flexibility. Instead, use a separate loan split.

Tax Considerations

Using equity to buy an investment property has significant tax implications. The key principle: interest deductibility depends on the purpose of the borrowed funds, not the security.

Deductible vs. Non-Deductible Debt

If you redraw equity from your home loan to fund an investment property, the interest on that portion becomes tax-deductible because the funds are used for income-producing purposes. However, if you use the equity for personal expenses (e.g., a new car), the interest is not deductible.

To maximise deductions:

• Set up a separate loan account or split for the investment portion. This creates a clear paper trail.
• Avoid mixing personal and investment borrowings.
• Keep detailed records of all transactions.

Negative Gearing

If the investment property’s expenses (including interest) exceed the rental income, you can claim a net rental loss against your other income, reducing your taxable income. This is known as negative gearing. In 2026, negative gearing remains available, but there is ongoing political debate about potential changes. The Australian Taxation Office (ATO) provides guidance on rental property deductions (ATO Rental Properties).

Capital Gains Tax (CGT)

When you sell the investment property, you’ll likely incur CGT on the profit. If you hold the property for more than 12 months, you may be eligible for a 50% CGT discount. The ATO also allows you to include certain costs in the cost base to reduce the gain.

Depreciation

Claiming depreciation on the building and plant and equipment can significantly boost deductions. Obtain a tax depreciation schedule from a qualified quantity surveyor.

Structuring Ownership

Consider whose name the investment property should be in. If one spouse has a higher income, owning it in their name can maximise negative gearing benefits. Alternatively, a discretionary trust may offer asset protection and income distribution flexibility, but trusts do not qualify for the 50% CGT discount and may have land tax surcharges.

Consult a tax professional before proceeding. The Tax Institute of Australia can help you find a registered tax agent (Tax Institute).

Risks and Mitigation

Leveraging equity is not without risk:

• Market Downturn: If property values fall, your equity could shrink, potentially putting you in negative equity. Mitigate by maintaining a buffer and not borrowing to the maximum.
• Interest Rate Rises: Higher rates increase repayments and reduce cash flow. Fixing part of your loan or ensuring you can service repayments at higher rates is prudent.
• Vacancy Periods: Without rental income, you must cover the mortgage. Have a cash reserve for at least 3–6 months of expenses.
• Tax Law Changes: Future changes to negative gearing or CGT could affect your strategy. Stay informed and flexible.

Case Study: Jane’s Equity Journey

Jane owns a home in Melbourne valued at $950,000 with a $350,000 mortgage. Her usable equity at 80% LVR is:

(950,000 × 0.80) – 350,000 = $410,000

She wants to buy an investment property in Brisbane worth $600,000. She needs:

• 20% deposit: $120,000
• Stamp duty and costs: ~$25,000
• Total: $145,000

She releases $150,000 from her equity via a loan split. Her home loan increases to $500,000, but the $150,000 split is used for the investment, so its interest is deductible. She borrows the remaining $480,000 as a separate investment loan. Her rental income covers most of the interest, and she claims depreciation, resulting in a small negative gearing benefit.

Conclusion

Using equity to buy an investment property in Australia in 2026 can be a smart strategy if done carefully. Understand your usable equity, choose the right loan structure, and be mindful of tax implications. Always conduct thorough research and seek professional advice from a mortgage broker, accountant, and financial planner. With the right approach, you can grow your property portfolio and build long-term wealth.

FAQ

1. Can I use equity if I have a low income?

Yes, but your borrowing capacity may be limited. Lenders assess your ability to service the new debt. If your income is low, consider a lower-priced investment or wait until your income increases. Some lenders may use a higher proportion of rental income for serviceability, so shop around.

2. Is it better to use a line of credit or a loan increase?

A separate loan split or line of credit is generally better for tax purposes because it clearly separates deductible and non-deductible debt. A loan increase mixes the purposes, making interest apportionment more complex. Consult your accountant.

3. What if my property value has dropped?

If your equity has decreased, you may not be able to release enough funds. You could wait for values to recover, save a cash deposit, or consider a lower LVR loan with LMI. Avoid selling in a down market if possible.

4. How does equity release affect my credit score?

Applying for equity release involves a credit enquiry, which may temporarily lower your score. However, if you manage the new debt responsibly, your score should recover. Multiple applications in a short period can be a red flag to lenders.
