For many homeowners, building equity is one of the biggest financial milestones they’ll achieve.
As property values increase and home loans are gradually paid down, it’s natural to start thinking about how that equity could help fund the next step—whether that’s buying an investment property, upgrading to a larger home, renovating, or consolidating debt.
But here’s something I often remind borrowers: Having equity and being ready to use it aren’t always the same thing.
Accessing equity can certainly create opportunities, but it also means increasing your debt and taking on greater financial responsibility. Before you decide to unlock the value in your home, it’s worth stepping back and looking at the bigger picture. The goal isn’t simply to access equity—it’s to use it in a way that supports your long-term financial goals.
INSIDE THIS GUIDE
Quick Answer: What Should You Consider Before Using Equity?
Using equity can be a smart way to finance your next property purchase or achieve other financial goals, but it’s important to remember that equity isn’t “free money.” When you access equity, you’re increasing the amount you’ve borrowed against your home.
Before moving ahead, ask yourself:
Can I comfortably afford the higher repayments?
Do I understand the difference between total equity and usable equity?
Am I keeping enough savings aside as an emergency buffer for unexpected expenses?
Does this additional borrowing explicitly support my long-term financial goals?
Have I stress-tested my budget to see how higher interest rates would affect my cash flow?
Thinking through these core questions now can prevent severe financial strain later.
First Things First: Understand What Equity You’re Actually Using
One of the biggest misconceptions I hear from borrowers is: “My property has gone up by $300,000, so I can use all of that equity to buy another home.”
Unfortunately, it doesn’t quite work that way. There is a critical difference between your Total Equity and your Usable Equity.
1. Total Equity
This is simply the absolute difference between your property’s current market value and the balance remaining on your home loan. This is your pure paper ownership in the property.
2. Usable Equity
This is the portion a lender may actually allow you to borrow against. Most banks limit your total borrowing to 80% of your property’s value to avoid Lenders Mortgage Insurance (LMI).
While having $220,000 in usable equity is an incredible starting point, it does not guarantee immediate finance approval. To unlock that money, you must still prove to the lender that your income can comfortably support the new loan.
The Reality: Equity Isn’t Free Money
This is probably the most important point in this entire guide. Releasing equity is not like withdrawing cash from a savings account.
When you unlock equity, you are taking on additional debt that is secured against your home. This means:
- Your total loan balance increases.
- Your monthly repayments will rise.
- You will pay interest on that additional borrowing for the life of the loan.
Used wisely, equity can help you buy an investment property and build long-term wealth. Used without a structured, analytical approach, it can place unnecessary pressure on your household budget for decades. That’s why I always encourage borrowers to think about why they are accessing equity—not just whether they are allowed to.
Can You Comfortably Afford the Extra Repayments?
Having usable equity is only the first hurdle. Lenders must evaluate your ability to manage the higher debt comfortably under their responsible lending policies. This is known as serviceability.
When evaluating your capacity to service a larger loan, lenders look far beyond your base salary. They perform a deep analysis of your complete financial portfolio, including:
“Would my budget still feel comfortable if rates increased or my household circumstances changed?”
Lenders apply an interest rate serviceability buffer (often around 3 percentage points above the product rate) to test whether you can withstand rate fluctuations. Thinking through different scenarios yourself rather than letting the bank’s automated calculators dictate your limits will help ensure your long-term comfort.
Don’t Use Every Dollar of Available Equity
Just because a lender says you are approved to borrow up to a certain limit does not mean you should take it all. Keeping a portion of your usable equity untouched acts as an incredibly valuable strategic lever.
Leaving a buffer ensures you can:
- Manage unexpected urgent home repairs or structural maintenance.
- Handle periods of temporary income changes, such as maternity leave or career transitions.
- Move fast when unexpected, highly lucrative investment opportunities present themselves.
- Minimize overall financial pressure during broader macroeconomic shifts.
Similarly, it is crucial to keep an emergency cash reserve completely outside your property portfolio. While property equity is valuable, it is highly illiquid and cannot be used to pay next week’s grocery bills if you suddenly experience a cash flow emergency. Balancing available equity and easily accessible savings is the hallmark of a resilient portfolio.
Be Careful How Your Loan Is Structured
The underlying structure of your equity release is often overlooked, but it has huge tax and strategic consequences. If you are accessing equity to purchase an investment property, it’s generally best to keep that debt separate rather than combining everything into one massive home loan.
Splitting loan accounts makes your interest expenses easier to track, ensures clean record-keeping for tax deductions, and simplifies accounting at tax time.
The Risks of Cross-Collateralisation
Cross-collateralisation occurs when a lender uses multiple properties as security for a single loan package. While this might seem convenient during the initial setup, it severely limits your future flexibility:
-
✘
Complex Selling Processes: If you sell one property, the lender may force you to use the sale proceeds to pay down the debt on the remaining property rather than letting you keep the cash. -
✘
Refinance Roadblocks: Moving one of your loans to a different lender is significantly harder because your assets are legally tangled. -
✘
Valuation Bottlenecks: A downward valuation on one property can restrict your borrowing power across your entire portfolio, even if your other assets have surged in value.
Most sophisticated property investors intentionally keep each property’s lending structure entirely standalone to protect their assets and maintain absolute control.
Don’t Forget the Hidden Costs
Accessing equity comes with transaction costs that can quickly add up. Before finalizing your plans, ensure you’ve budgeted for both the upfront lending setup fees and the property transaction costs:
Upfront Lending Fees
- Independent property valuation fees
- Lender setup or loan application fees
- Mortgage registration and government costs
- Legal, settlement, or conveyancing fees
- Exit or break costs (if breaking fixed rates)
Property Purchase Costs
- State government stamp duty
- Conveyancing and title transfer fees
- Building and pest inspection reports
- Landlord, building, or strata insurance policies
- Initial property manager holding fees
Equity Should Support Your Strategy—Not Become the Strategy
One of the biggest mistakes borrowers make is letting available equity drive their investment decisions. Your ultimate financial goals should always dictate your actions. Equity is simply a vehicle to help you get there.
If you are planning to purchase your next property using your home’s equity, take the time to learn how to buy your next home without a cash deposit. Likewise, if you are looking to unlock equity by switching banks, it’s worth reviewing our ultimate refinancing guide to see if a rate transition is right for you. And remember, if one lender declines your application, don’t assume your plans are over—learn how banks evaluate investment loans to find a lender that favors your situation.

Closing Thoughts
Building equity is an incredible milestone, and for many Australians, it provides a powerful launching pad to grow long-term wealth.
However, it should never be treated as “free money” sitting in a traditional savings account. Every dollar you release becomes active debt secured against your home, increasing your total exposure and your ongoing financial commitments.
That’s why the most successful borrowers don’t simply ask, “How much can I borrow?” Instead, they ask, “Will this borrowing structure move me closer to my financial goals?” When equity is used thoughtfully and strategically, it can help you unlock powerful opportunities. The key is ensuring that today’s borrowing fully supports tomorrow’s plans.
