Understanding the Basics of Using Home Equity

If you own a home in Melbourne and have been paying down your mortgage, you likely have equity available that could fund the deposit for a second property.

Equity is the difference between what your property is worth and what you still owe on it. As you make repayments and as property values rise, that gap widens. Refinancing lets you borrow against that equity without selling your home, giving you access to funds you can use as a deposit for an investment property or second home.

What Equity Release Through Refinancing Actually Means

Releasing equity means increasing your loan amount to access a portion of the value you have built up in your property. Lenders typically allow you to borrow up to 80% of your property's current value without needing to pay lenders mortgage insurance, though some will lend up to 90% or higher if you meet their criteria. The amount you can access depends on your property's valuation, your existing loan balance, and your borrowing capacity.

Consider a homeowner in Coburg whose property is now valued at $900,000 with $400,000 remaining on the mortgage. At 80% LVR, they could borrow up to $720,000 against the property. After paying out the existing $400,000 loan, they would have $320,000 available. After keeping a buffer for costs and retaining some equity, they might access around $280,000 to use as a deposit on an investment property. This approach lets them enter the investment market without needing to save a second deposit from scratch.

How Lenders Assess Your Refinance Application

Lenders evaluate your ability to service the higher loan amount before approving equity release. They consider your income, existing debts, living expenses, and the rental income the new property might generate if it is an investment. Your borrowing capacity determines how much you can access, not just how much equity you have on paper.

If the numbers show you can comfortably manage repayments on both properties, lenders will generally support the refinance. If your income or employment situation has changed since you first borrowed, or if interest rates have risen significantly, you may not be able to access as much as the equity calculation suggests. A broker can model different scenarios with you and help structure the application to give you the strongest position.

Structuring Loans Across Two Properties

Once you refinance and access equity, you need to decide how to structure your loans. Some borrowers keep one loan secured against the original property and take out a separate loan for the investment purchase. Others split the borrowing across both properties using cross-securitisation, where both properties secure both loans.

Keeping the loans separate generally offers more flexibility if you decide to sell one property later, as you won't need the other lender's consent to discharge the mortgage. It also makes tax reporting clearer, since the interest on the investment loan is typically tax-deductible while the interest on your home loan is not. Splitting loans this way does add complexity, and you will need to consider whether holding costs and serviceability stack up across two separate facilities. Working with someone who understands investment loans and how they interact with your existing home loan helps you set up a structure that suits your situation and goals.

LVR Limits and Lenders Mortgage Insurance

Most lenders cap borrowing at 80% of your property's value if you want to avoid lenders mortgage insurance. Going beyond that threshold means paying a one-off premium that can run into thousands of dollars, depending on the loan size and LVR. In some cases, paying LMI makes sense if it lets you move sooner or secure a property in a rising market, but it does add to your upfront costs.

If you are refinancing to release equity and using those funds for an investment deposit, lenders will also assess the LVR on the new property. If you are putting down a 20% deposit on the investment and borrowing 80%, you avoid LMI on that loan as well. If you stretch further and use less equity as a deposit, you may trigger LMI on the investment loan, the refinance, or both. Understanding where those thresholds sit across both properties lets you plan your borrowing to keep costs down.

Borrowing Capacity and Serviceability Across Multiple Properties

Accessing equity is only part of the equation. You also need to demonstrate that you can afford the repayments on both loans. Lenders assess this using your income, existing commitments, and the rental income the investment property might generate. They typically apply a discount to that rental income, assuming vacancy periods and applying a buffer to interest rates when calculating serviceability.

If you are stretching your borrowing capacity to access equity and purchase a second property, small changes in interest rates or rental income can affect your ability to manage both loans comfortably. Lenders will stress-test your application at higher rates than you will actually pay, so even if repayments feel manageable now, you need to show you could still cover them if rates rise. This is where having a buffer in your budget and understanding your genuine capacity becomes important, not just what a lender is willing to approve.

Tax and Offset Account Considerations

When you refinance to access equity for investment purposes, how you structure your offset accounts and redraw facilities affects your tax position. Interest on borrowings used to purchase an income-producing asset is generally tax-deductible, while interest on your home loan is not. Mixing these loans or depositing savings into an offset account linked to your home loan instead of your investment loan can dilute your deductions.

Keeping funds in an offset account linked to your owner-occupied loan reduces the interest you pay on non-deductible debt, which is usually the most tax-effective approach. Paying extra into your investment loan or using redraw on it can reduce your deductible interest, which works against you at tax time. Setting this up correctly from the start avoids issues later, and it is worth discussing the structure with both your broker and accountant before finalising the refinance.

Timing and Valuation Risk

Property valuations can vary depending on the valuer, recent sales in your area, and market conditions at the time of your application. If your property is valued lower than you expect, the amount of equity you can access shrinks. In some Melbourne suburbs, valuation outcomes can be influenced by factors like recent apartment settlements, local infrastructure changes, or seasonal market shifts.

If you are relying on a specific equity amount to fund your investment deposit and the valuation comes in lower, you may need to adjust your purchase budget, contribute additional cash, or wait until your property value increases. Locking in a purchase before confirming your refinance approval and valuation can leave you exposed if the numbers do not align. Coordinating the timing between your refinance and your investment purchase, and building in a margin for valuation variance, reduces that risk.

When Refinancing to Access Equity Makes Sense

Refinancing to release equity works when you have sufficient equity available, strong serviceability, and a clear plan for how the funds will be used. It suits borrowers who want to build a property portfolio without liquidating their existing home or waiting years to save another deposit. It also works when your current loan rate is higher than what is available in the market, so you can improve your rate and access funds in the one transaction.

It is less suitable if your income has dropped, your expenses have increased significantly, or if accessing equity pushes your LVR so high that you are paying LMI and stretching serviceability to uncomfortable levels. Refinancing to access equity for investment should improve your financial position over time, not just let you acquire another property at any cost. If the numbers are tight or the investment does not generate enough return to justify the additional debt, it may be worth waiting until your equity or income position improves.
