If you own property in Queensland and want to buy another home without selling your current one, the equity sitting in your existing property can fund most or all of your next purchase.
Your home equity represents the portion of your property you actually own outright. Calculate it by subtracting what you owe on your mortgage from what your property is worth today. Most lenders will let you borrow against up to 80% of your property value, though some will go higher with lender's mortgage insurance. That accessible amount becomes your deposit and buying costs for the second property.
How Lenders Calculate Available Equity
Lenders multiply your property's current value by 80%, then subtract your remaining loan balance. The result is what you can access without paying lender's mortgage insurance. Consider a homeowner with a property valued at $700,000 and an outstanding loan of $350,000. The lender calculates 80% of $700,000, which equals $560,000. Subtract the $350,000 loan balance and $210,000 becomes available as usable equity. That amount can cover a deposit on a second property plus associated buying costs like stamp duty, conveyancing, and building inspections.
This approach works when your borrowing capacity supports holding both loans simultaneously. Lenders assess your income against the combined repayments of your existing mortgage and the new loan you're applying for. If your income comfortably services both, the equity becomes your pathway to the next purchase.
Usable Equity vs Total Equity
Total equity is the full difference between your property value and loan balance. Usable equity is the amount a lender will actually let you access. If you own a property worth $600,000 with a $200,000 mortgage, your total equity sits at $400,000. Your usable equity, calculated at 80% of the property value minus the loan, equals $280,000. The remaining $120,000 stays untouched as your equity buffer.
Lenders impose this buffer to protect both you and them against property value fluctuations. If property prices drop, that 20% cushion prevents you from owing more than the property is worth. Accessing more than 80% requires lender's mortgage insurance, which adds cost but remains an option if your equity sits just below what you need.

When Equity Access Makes Sense for a Second Home
Using equity works when you're buying a property to live in while keeping your current home as an investment property. Your original home converts to an investment, and rental income offsets some of the holding costs. Lenders typically accept 80% of rental income when calculating your borrowing capacity, which can bridge the gap between your salary and the combined loan repayments.
In our experience, this structure suits buyers who've built substantial equity through property value growth or mortgage repayments and want to upgrade their living situation without selling. The rental income on the first property supports the investment loan, while your salary services the new home loan. Both properties remain in your name, and you benefit from any future capital growth on each.
Structuring Loans When Using Equity
You'll need to refinance your existing home loan or establish a separate line of credit to release the equity. Most borrowers refinance the original property loan, increasing the loan amount to access the equity while keeping the new property purchase as a separate loan facility. This separation keeps your owner-occupied loan distinct from your investment loan, which matters for tax purposes since interest on investment loans is generally tax-deductible.
Consider a scenario where you own a home valued at $650,000 with $300,000 owing. You want to buy a second property at the current median for your target suburb. Refinancing the original loan to $520,000 (80% of $650,000) releases $220,000 in equity. That amount covers a deposit and buying costs on your next purchase, while the original property transitions to an investment with its own loan structure. Your new property becomes your primary residence with a separate home loan.
Lenders assess both loans together but apply different interest rates and terms based on whether the loan is for owner-occupied or investment purposes. Investment loans typically carry slightly higher interest rates but offer tax benefits through deductible interest payments.
Deposit Requirements and Lender's Mortgage Insurance
When you use equity to fund a second property purchase, the equity you access functions as your deposit. Lenders still expect you to meet standard deposit requirements, typically 20% of the purchase price plus costs. If your usable equity falls short, you can access more than 80% of your original property's value by paying lender's mortgage insurance on the shortfall.
Some borrowers combine usable equity with a smaller cash deposit to reach the 20% threshold and avoid lender's mortgage insurance on the new purchase. Others accept the insurance cost to move forward sooner rather than waiting for more equity to accumulate. The decision depends on how much your equity shortfall is and how urgently you want to buy.
Income Assessment Across Two Properties
Your income needs to service both loans simultaneously. Lenders add your existing mortgage repayment to the proposed new loan repayment, then compare that total against your income using their serviceability buffers. They also factor in living expenses, other debts, and a buffer above the actual interest rate to ensure you can manage repayments if rates rise.
If you're converting your original home to an investment, lenders include rental income in their assessment. They apply a reduction, usually accepting 80% of the rental amount, to account for vacancy periods and maintenance costs. This rental income can significantly improve your borrowing capacity and make holding both properties viable. We regularly see buyers who couldn't service two loans on salary alone become approved once rental income enters the calculation.
Costs Beyond the Deposit
Accessing equity covers more than just the deposit on your second property. Stamp duty in Queensland varies by purchase price and property type, and you'll also need to budget for conveyancing, building and pest inspections, and loan establishment fees. If you're refinancing to release equity, factor in discharge fees on your old loan and application fees for the new loan structure.
These costs add up quickly. On a property purchase at the current median in many Queensland suburbs, total buying costs excluding the deposit can reach $20,000 to $35,000. Your released equity needs to cover both the deposit and these additional expenses, so calculate the full amount before committing to a purchase price.
Frequently Asked Questions
How much equity can I access to buy a second property?
Most lenders allow you to borrow up to 80% of your current property's value. Subtract your remaining loan balance from that 80% figure, and the result is your usable equity. Accessing more than 80% is possible but requires lender's mortgage insurance.
Do I need to sell my first home to buy a second property using equity?
No, you keep your first property and convert it to an investment or retain it as a second home. The equity you access funds the deposit and costs for your next purchase. Both properties remain in your ownership.
How do lenders assess my income when I'm buying a second property?
Lenders evaluate your ability to service both loans at the same time. They assess your income against the combined repayments, factoring in living expenses and interest rate buffers. If your first property becomes an investment, they include 80% of expected rental income in their calculation.
Can I use equity if I have less than 20% available as a deposit?
Yes, you can access more than 80% of your property value to increase available equity, but you'll pay lender's mortgage insurance on the portion above 80%. Some borrowers combine their usable equity with additional savings to reach the required deposit amount.
What costs does my equity need to cover besides the deposit?
Your equity should cover the deposit plus stamp duty, conveyancing fees, building and pest inspections, and loan establishment fees. In Queensland, these additional costs can range from $20,000 to $35,000 depending on the purchase price.
