When to Refinance & Use Equity for a Second Property

Using Home Equity to Fund a Second Property Purchase

Refinancing to release equity lets you borrow against the value your current property has gained, then use that cash as a deposit for an investment property. The lender increases your loan amount based on your available equity position, and you walk away with funds that can cover a 10% to 20% deposit plus purchase costs on a second property.

This approach works when your property value has increased since you bought it, or when you've paid down enough of the loan to create usable equity. You need at least 20% equity remaining in your current property after the refinance to avoid lenders mortgage insurance on the new loan amount. The funds released act like cash in your account, which means you can move quickly when the right investment opportunity appears.

Consider someone who bought a unit five years ago for $450,000 and now owes $320,000 on the loan. If the property is now worth $550,000, they have $230,000 in equity. A lender will typically let them borrow up to 80% of the property value, which is $440,000. That leaves $120,000 they can access through refinancing. After keeping a buffer for refinance costs, they have around $115,000 available to put toward a second property deposit and associated costs.

How Lenders Calculate Your Available Equity

Lenders use your loan to value ratio to determine how much equity you can access. They take your current property value, multiply it by 80%, then subtract what you still owe. The difference is your available equity, though most brokers recommend holding back 5% to 10% as a buffer rather than borrowing to the maximum.

If your property is worth $600,000 and your loan sits at $380,000, the lender allows you to borrow up to $480,000. That gives you $100,000 in accessible equity. The actual amount you can use depends on your borrowing capacity, which factors in your income, existing debts, living expenses, and the servicing requirements for both the increased loan on your current property and the new investment loan on the second property.

Lenders assess whether you can service both loans at the same time. They calculate repayments using a buffer rate that sits 2% to 3% above current variable rates, so your income needs to comfortably cover both loans even if rates rise. This serviceability test is the main reason some applicants get approved for equity release but can't proceed with the second property purchase. Your income has to support the total debt, not just the equity you want to access.

When Refinancing for Equity Makes Sense

Refinancing to access equity works when your property has gained value, when you've reduced your loan balance significantly, or when both have occurred together. It also makes sense if current interest rates sit at or below what you're paying now, because you can release funds without increasing your repayment burden significantly.

You need a clear plan for the second property before refinancing. Lenders want to see that the equity release is funding a specific purchase, not sitting idle in an offset account. If you're targeting an investment property in a growth area or one that generates strong rental yield, the income from that property helps with serviceability and strengthens your application.

Timing matters when the property market is moving. In our experience, buyers who have their equity release loans pre-approved and funds ready can negotiate more effectively, particularly at auction or when competing against other buyers. Sellers and agents respond differently when they know your finance is already locked in.

The Costs Involved in Equity Release Refinancing

Refinancing to release equity involves upfront costs that reduce the amount you actually walk away with. Expect to pay for a property valuation, discharge fees from your current lender, application fees for the new loan, and legal costs for the mortgage documentation. These costs typically sit between $2,000 and $4,000, depending on your lender and property location.

Some lenders offer refinance packages that waive application fees or include a free valuation, but you need to weigh those benefits against the interest rate and loan features. A loan with no application fee but a rate that's 0.15% higher will cost you more over time than paying the upfront fee and securing the lower rate.

If you're refinancing a loan that has a fixed rate period still active, break costs apply. These can run into thousands of dollars if rates have dropped since you fixed, because the lender calculates the interest income they'll lose by letting you exit early. Variable rate loans don't carry break costs, which makes them more flexible for equity release refinancing.

Structuring Loans Across Two Properties

Most buyers keep the equity release as a separate loan split on their current property rather than blending it into one large loan. This structure lets you claim the interest on the equity portion as a tax deduction if you're using it to fund an investment property, while the interest on your original home loan remains non-deductible.

The second property gets its own investment loan, often structured as interest-only to keep repayments lower while the property builds equity and generates rental income. Interest-only loans reduce your monthly commitments, which improves cash flow and helps you hold the property long-term without selling due to repayment pressure.

Your broker will structure the debt so the investment property loan is clearly separated from your home loan. This separation protects your tax position and makes it simpler to manage repayments, offset accounts, and future refinancing. Blending the loans creates complications later when you need to prove which portion of the debt relates to the investment property.

Risks and Limitations of Using Equity

Borrowing against equity increases your total debt, which means higher repayments and more exposure to interest rate movements. If rates rise by 1%, your repayments increase across both loans. You're also holding two properties, so maintenance costs, council rates, insurance, and other ownership expenses double.

If property values drop after you refinance, your equity position shrinks. In a falling market, you could end up with less than 20% equity in one or both properties, which limits your ability to refinance again or access further funds. Lenders reassess your equity each time you apply, so a valuation that comes in lower than expected can block your plans.

The second property needs to generate enough rental income to cover most of its holding costs, or your cash flow will tighten quickly. We regularly see buyers underestimate the gap between rental income and total ownership costs, particularly in the first few years when the property might sit vacant between tenants or require unexpected repairs. Build a buffer of at least three months' holding costs before committing to the second property.

Alternatives to Equity Release for Second Property Purchases

If refinancing to access equity doesn't suit your situation, you can use a guarantor structure where your current property acts as security for part of the second property loan. This approach avoids increasing your current loan but still uses your equity to support the new purchase. It requires careful structuring to protect both properties and limit your risk.

Another option is debt recycling, where you pay down non-deductible debt on your home while simultaneously drawing on equity to fund deductible investment debt. This strategy takes longer but gradually converts your debt into a tax-effective structure while building your property portfolio.

Some buyers focus on saving a deposit separately rather than using equity, particularly if their current loan has favourable terms they don't want to disrupt or if refinancing costs outweigh the benefits. This approach takes longer but avoids increasing debt on your primary residence and keeps your loans completely separate from the start.

Refinancing to access property equity for a second property works when your numbers stack up, your income supports both loans, and the investment property makes sense on its own merit.
