Buying, investing or refinancing in Brisbane's South? We can help, just get in touch here.

Using your home equity to buy another property can be a smart strategy when it’s structured correctly. Many Brisbane South homeowners consider this approach when upgrading, investing, or helping family members enter the property market, particularly as property values continue to rise.

The challenge is that equity is often misunderstood. Some borrowers assume they can access all of it, which can lead to declined applications or unnecessary financial pressure if lender requirements aren’t met.

That’s where a mortgage broker can add real value. With a strong understanding of lender policies and loan structuring, an experienced Brisbane South broker, such as AE Finance Solutions, can help you access equity safely and utilise it in a way that aligns with your borrowing capacity and long-term financial goals.

Let’s break down what’s involved in using equity to purchase your next property.

What Does It Mean to Use Home Equity to Buy a Home?

Using home equity to buy a home means borrowing against the value you’ve built up in an existing property to help fund the purchase of another property. Home equity is the difference between your property’s current market value and the amount you still owe on your mortgage, and lenders typically allow you to access a portion of this equity rather than the full amount.

This strategy is commonly used by existing homeowners and property investors to cover deposits or purchase costs without selling their current property, provided they meet lender serviceability and risk requirements.

How Does Using Equity to Buy a Home Work?

Using equity to buy a home involves borrowing against the increased value of your current property rather than saving for a deposit. It’s about how lenders calculate and release that equity, not about applying or qualifying just yet.

Before diving into the steps, here’s how it works in practice:

The lender orders a valuation to assess your property’s current market value.
Usable equity is calculated, typically 80% of your property’s value, minus what you still owe.
That equity is then released as additional borrowing, secured against your home.
The released funds are used toward the deposit or full/partial cost of the new property.

Sample scenario:

Let’s say your home in Brisbane South is now worth $800,000, and you owe $400,000 on your mortgage.

Calculation:

80% of $800,000 = $640,000
$640,000 – $400,000 (existing loan) = $240,000 usable equity

That $240,000 can potentially be used as a deposit on your next property, subject to lender approval.

Steps to Use Equity to Buy a Home in Brisbane South

Here are the 7 practical steps to safely use your equity to buy another property in 2026:

1. Work Out Your Property’s Current Value

Get a formal property valuation through your broker or lender to determine your home's current market value.

2. Calculate Your Usable Equity

Subtract your remaining loan balance from 80% of your home’s value. This is what lenders usually allow without needing Lenders Mortgage Insurance (LMI).

3. Review Your Borrowing Capacity

Lenders will check your income, expenses, credit history, and any existing debts. Your usable equity doesn’t guarantee approval unless your cash flow supports it.

4. Choose a Suitable Loan Structure

Decide whether to top up your current loan, open a line of credit, or set up a separate investment loan. Your broker will help determine which is best for your goals.

5. Gather Documentation

Have your payslips, tax returns, ID, existing loan statements, and living expenses ready. Full-doc applications are still standard for equity access.

6. Submit Your Loan Application

Your broker will help package and submit your application, presenting your financials in line with lender policies to reduce approval risk.

7. Use Equity for the New Property Deposit

Once approved, the funds can be used as your deposit for a new home or investment property. The rest is funded through a new home loan.

What Are the Common Mistakes Borrowers Should Avoid When Using Equity?

Many borrowers make avoidable mistakes that can affect their borrowing power or long-term financial health.

Here are the most common pitfalls:

Overestimating usable equity – Not all equity is accessible; lenders typically cap it at 80% of your property’s value.
Ignoring serviceability requirements – Even with strong equity, you must still prove you can afford the total loan repayments.
Using equity for non-investment purposes – Borrowing against your home for lifestyle spending can reduce future borrowing options.
Not factoring in future rate rises – Higher repayments in a changing interest rate environment can strain your budget.
Failing to review loan structure – Using the wrong loan type (e.g., redraw vs. split loan) can affect flexibility and tax outcomes.
Skipping professional advice – DIY approaches often miss lender-specific rules or policy changes that impact approval.

Working with a mortgage broker helps you avoid these traps and make informed, strategic decisions.

FAQs About Using Equity to Buy a Home

How much equity do I need to buy another property?

Most lenders require you to have at least 20% usable equity to cover the deposit and avoid LMI. That means your current property should have increased significantly in value.

Can I use equity as a full deposit?

Yes, if you have enough usable equity and meet serviceability rules. However, you’ll still need to fund purchase costs like stamp duty and legal fees.

Will using equity increase my repayments?

Yes, because you’re increasing your total loan amount. Your broker will show you how much repayments could rise before you commit.

Do I need to get my property revalued?

Yes, lenders usually require a current valuation to assess your equity position. Your broker can organise this as part of the application process.

Is using equity tax-deductible?

If the equity is used for investment purposes, such as buying a rental property, interest on that portion may be tax-deductible. Speak to a tax adviser for advice.

Can I access equity if I’m retired or self-employed?

Yes, but lenders will closely assess your income or asset position. A broker can help structure your application based on your financial situation.

What’s the difference between equity and usable equity?

Equity is your property’s value minus what you owe. Usable equity is the portion of that total lenders will allow you to borrow against, typically up to 80%.
