How to Use Home Equity to Buy a Second Property

If you own property on the Mornington Peninsula and have built equity over time, you can access that value to fund a second property purchase without selling your current home.

Refinancing to release equity involves increasing your loan amount against your existing property, allowing you to borrow against the difference between what you owe and what your home is worth. The funds can then be used as a deposit or to cover purchase costs for an investment property, a holiday home, or even helping family members into the market. For many residents across suburbs like Mornington, Mount Eliza, and Dromana, this approach offers a pathway to property investment that doesn't require years of saving for another deposit.

What Is Usable Equity and How Much Can You Access?

Usable equity is the portion of your property's value that lenders will allow you to borrow against, typically up to 80% of the property's current value minus your existing loan balance.

Consider a scenario where your home is valued at $950,000 and you owe $450,000 on your mortgage. At 80% LVR, a lender would allow you to borrow up to $760,000. After repaying your current loan of $450,000, you would have access to $310,000 in usable equity. That amount could cover a deposit on an investment property in a nearby area, fund a smaller coastal property in Rye or Rosebud, or support a family member purchasing their first home. The actual amount you can access depends on your property's current value, your remaining loan balance, and the lender's assessment of your borrowing capacity.

How Refinancing to Release Equity Works

The process involves applying to either increase your loan with your current lender or refinancing to a new lender who will provide a larger loan amount based on your property's equity.

Your lender will order a valuation of your property to confirm its current market value. Once that's completed, they assess your income, expenses, and overall financial position to determine how much additional borrowing you can service. If approved, the new loan pays out your existing mortgage and the remaining funds are released to you, either as a lump sum or held in an offset account ready for when you need to settle on the second property. This approach keeps your existing home intact while unlocking capital that would otherwise remain tied up in bricks and mortar.

Structuring the Loan for a Second Property Purchase

Most borrowers choose to split the debt into two separate loans: one for the original home and one for the investment or second property.

This structure keeps the borrowing purpose clear, which matters for tax deductibility if the second property is an investment. The loan secured against your home remains linked to your primary residence, while the additional borrowing is quarantined to the new property. In practice, this means setting up a loan split at the time of refinancing so that interest on the investment loan portion can be claimed as a tax deduction, while the portion tied to your home cannot. Lenders are comfortable with this arrangement, and it provides clarity if you ever decide to sell one property or restructure your debt down the track.

LVR Limits and Lenders Mortgage Insurance

Borrowing above 80% of your property's value will trigger lenders mortgage insurance, which can add thousands of dollars to your upfront costs.

If you need to access more equity than the 80% threshold allows, you can still proceed, but the lender will charge LMI to protect themselves against the higher risk. For a property valued at $950,000 with an existing loan of $450,000, borrowing up to 90% LVR would give you access to $855,000 in total lending, or $405,000 in usable equity after the existing loan is repaid. However, LMI on that additional 10% could cost anywhere from $15,000 to $25,000 depending on the lender and loan amount. For some buyers, paying LMI is worthwhile if it means securing a property sooner, particularly in a rising market. For others, staying at or below 80% LVR and topping up savings separately makes more financial sense.

Borrowing Capacity and Serviceability

Releasing equity is only possible if you can demonstrate the capacity to service the higher loan amount, including any rental income from the new property.

Lenders assess your income, existing debts, living expenses, and the rental yield or holding costs associated with the second property. If you're purchasing an investment property in an area like Hastings or Somerville, the lender will factor in a percentage of the expected rental income, usually around 80%, to offset the additional loan repayments. If the property will be owner-occupied part of the time or held as a holiday home, serviceability becomes tighter because there's no rental income to offset the cost. Your borrowing capacity determines whether the refinance is approved, regardless of how much equity you have available. In our experience, this is where many applications stall, particularly for self-employed borrowers or those with recent changes to their income.

Using Equity for a Family Transfer or Co-Purchase

Some Mornington Peninsula residents use released equity to help adult children enter the property market, either through a gift or a co-purchase arrangement.

In a scenario like this, a parent might refinance to release $150,000 in equity and contribute that amount as a deposit for their child's first home. The funds can be gifted outright or structured as a loan between family members, though the latter requires careful documentation to satisfy lender requirements. Alternatively, the parent might co-purchase the property with their child, using the released equity as the deposit and appearing as a co-borrower on the new loan. Both approaches have implications for tax, estate planning, and ongoing liability, so they require proper advice before proceeding. Lenders will assess the arrangement closely, particularly if the parent's name is on the new loan, as it affects their overall debt position and serviceability.

Costs Involved in Refinancing to Access Equity

Refinancing to release equity involves valuation fees, discharge fees from your current lender, application fees with the new lender, and potentially legal or conveyancing costs.

Valuation fees typically sit between $200 and $600 depending on the property type and location. Discharge fees from your current lender range from $150 to $400, while the new lender may charge an application or establishment fee of $600 or waive it entirely depending on the loan product. If you're refinancing to a lender that requires a separate mortgage document, legal fees of around $800 to $1,200 may apply. These costs should be factored into your decision, particularly if the amount of equity you're releasing is relatively modest. A loan health check can help clarify whether refinancing makes financial sense once all costs are accounted for.

Timing and Settlement Considerations

Refinancing to access equity takes time, so starting the process well before you need the funds is important.

From application to settlement, the process typically takes four to six weeks, though it can stretch longer if there are valuation delays or if the lender requests additional documentation. If you've already found a second property and signed a contract, the refinance needs to settle before your purchase settlement date, which can create timing pressure. For this reason, many buyers start the refinance process before they begin property hunting, so the funds are ready when the right opportunity appears. Lenders can provide conditional approval based on an estimated property value, but final approval depends on the valuation coming in at or above that figure.

Refinancing to release equity is a practical option for Mornington Peninsula residents who want to expand their property portfolio or support family without liquidating their current home. The process requires careful attention to serviceability, loan structure, and timing, but when managed properly, it provides access to capital that would otherwise sit idle.
