For most Australian homeowners, the best way to get cash from home equity is through a line of credit, a top-up (equity release) home loan, or a cash-out refinance – and each method works differently depending on your goals, income, and how much flexibility you need. Most lenders will let you access up to 80% of your property’s current value minus what you still owe, which means a well-positioned homeowner can unlock hundreds of thousands of dollars without selling. The right structure matters enormously, because it affects how much interest you pay, what is tax-deductible, and how quickly you can reinvest.
Think of your home as a piggy bank that grows over time. Every mortgage repayment you make, and every dollar your property increases in value, adds to what is locked inside. Home equity is simply the difference between what your property is currently worth and what you still owe on it.
Here is a straightforward example. Your home is worth $600,000 and you owe $150,000. Your total equity is $450,000. But banks do not let you access all of it. They require you to keep at least 20% of the property’s value as a buffer, so they will lend you up to 80% of $600,000 – which is $480,000. Subtract your existing $150,000 loan and your usable equity is $330,000.
I know this works because I have lived it. My very first property purchase was in Melbourne in 2001. I bought for $425,000 with only a 5% deposit – most of my remaining cash went straight to government fees and insurance, so there was very little left over for comfort. What I did have was a clear renovation plan and the conviction to back it. Nine months later, the property was valued at $700,000. I did not sell. Instead, I pulled the equity out, kept the asset, and used those funds as the deposit on my next purchase. Then I did it again. That is how my portfolio began – not by earning more, not by saving harder, but by understanding that the equity sitting inside one property could become the engine for the next one. Today, I have never sold a single one of those properties. That first decision to access equity rather than sit on it – and to structure it correctly from the start – is the reason my husband was able to retire from his software career at 40 and pursue his passion as a full-time artist.
That $330,000 can become a deposit on an investment property, funds to renovate and increase your home’s value, or a strategic financial reserve – without selling a single brick. This is how many Australians who have built serious property portfolios actually got started. They did not save more. They leveraged what they already had.
Understanding the mechanics of each option is critical before you act. Getting this wrong means either paying unnecessary interest or losing valuable tax deductions.
A line of credit works like a large credit facility secured against your home. The lender approves a set limit – say $300,000 – and you draw only what you need, when you need it. You only pay interest on the amount you have actually drawn, not the full limit.
So if you access $120,000 to fund a deposit on an investment property, you are only paying interest on $120,000. As you repay, those funds become available to draw again. This gives you genuine control over your debt and a built-in financial buffer for future opportunities.
For property investors, a line of credit is particularly powerful because it can be used and replenished multiple times as you build your portfolio.
This is the more traditional route. You go back to your existing lender and ask to increase your loan by the amount of equity you want to access. The bank revalues your property, confirms your borrowing capacity, and approves a lump sum added to your current mortgage.
It is straightforward, but less flexible than a line of credit. You receive the full amount upfront and begin paying interest on all of it immediately – even if you only need part of it at first. This option suits people who know exactly how much they need and want a predictable repayment plan.
Refinancing involves replacing your existing loan with a new, larger loan and using the difference as cash. This is popular when homeowners can also secure a lower interest rate at the same time.
The benefit is that you can reduce your rate while accessing equity in a single transaction. The downside is that refinancing comes with costs – discharge fees, application fees, legal fees, and sometimes break costs if you are exiting a fixed rate. Understanding how much it costs to refinance in Australia before proceeding is an important step.
The 80% loan-to-value (LVR) rule governs how much most Australian lenders will approve. Here is the formula:
(Property Value x 80%) – Outstanding Loan Balance = Usable Equity
| Property Value | Outstanding Loan | 80% LVR Cap | Usable Equity |
| $500,000 | $100,000 | $400,000 | $300,000 |
| $750,000 | $250,000 | $600,000 | $350,000 |
| $1,000,000 | $400,000 | $800,000 | $400,000 |
Some lenders will go beyond 80% LVR, but Lenders Mortgage Insurance (LMI) becomes payable, which adds a significant upfront cost. In most cases, staying within the 80% threshold is the smartest approach.
A critical piece of advice: do not draw your line of credit all the way to its limit. Keeping a buffer of at least 20% of your available credit gives you protection if property values soften, your income changes, or a new investment opportunity emerges. Your borrowing capacity is also assessed on your overall debt position, so maintaining headroom helps you qualify for future lending too.
This is the detail that separates good equity strategy from costly mistakes.
In Australia, interest on debt used to purchase an income-producing asset – such as an investment property – is generally tax-deductible. Interest on debt used for personal purposes, such as a renovation on your own home, a holiday, or a car, is not.
If you draw on a line of credit or top up your owner-occupier home loan and mix investment funds with personal spending, you create what is known as a “contaminated” loan. Once mixed, it is very difficult to separate for tax purposes, and you risk losing deductions you should legitimately be claiming.
The clean solution is to keep investment debt in its own loan account, separate from your personal mortgage. This way the interest on each is clear, auditable, and fully compliant with ATO requirements. Getting this structure right from the very beginning can save you thousands of dollars each financial year. You can also use the financial freedom framework to map out your broader debt and equity strategy before you take action.
Accessing your equity makes sense when:
It makes less sense when:
For investors building a portfolio, the equity in one property can become the deposit for the next. Over a decade, it is entirely realistic to compound a modest equity base into a multi-property portfolio – as long as each step is structured correctly and serviceability is maintained. The guide on how to build a profitable investment property portfolio walks through exactly this approach.
Many homeowners focus on how much equity they can access. The sharper question is how it should be structured.
Before approaching a lender, have a clear conversation about:
Getting this advice from a mortgage broker – rather than walking straight into a bank – means you are comparing options across multiple lenders, not just the one you already bank with.
Your home equity is one of the most powerful financial tools you have – but only if it is used strategically and structured correctly. The three main ways to get cash from home equity are a line of credit, a top-up loan, and a cash-out refinance. Each works differently, and the best choice depends on your goals, income, and how you plan to invest the funds.
The most important principle is this: borrow for assets, not liabilities. Keep your investment debt clean and separate. Maintain a buffer. And before you draw a single dollar, make sure the structure is right from the start.

How do I calculate how much equity I can cash out of my home?
Use the 80% LVR formula: multiply your property’s current market value by 0.80, then subtract your outstanding loan balance. For example, a $700,000 home with $200,000 owing gives you 80% x $700,000 ($560,000) minus $200,000, leaving $360,000 in usable equity. Note that lender approval also depends on your income, expenses, and overall borrowing capacity – the formula gives you the maximum, not a guaranteed figure.
What is the difference between a home equity loan and a line of credit in Australia?
A home equity loan (or top-up loan) gives you a lump sum that you begin repaying immediately, with interest charged on the full amount from day one. A line of credit gives you a pre-approved limit that you can draw from as needed, with interest charged only on the balance actually drawn. A line of credit is more flexible for staged investments; a top-up loan is simpler if you have a fixed, known expense.
Is the interest on a home equity loan tax-deductible in Australia?
Only if the funds are used for investment purposes, such as purchasing an income-producing property or shares. Interest on equity used for personal spending – renovations on your home, holidays, or a car – is not deductible. This is why keeping investment equity in a separate loan account from day one is so important, as mixing the two creates tax complications that are very difficult to untangle later.
Can I use home equity to buy an investment property?
Yes, and it is one of the most common ways Australian property investors fund their next purchase without needing a traditional cash deposit. You access the equity in your existing property and use it as the deposit (and sometimes for additional costs like stamp duty) on the investment. The key requirement is demonstrating to the lender that you can service both your existing mortgage and the new investment loan – which a good mortgage broker can help you assess and prepare for.
