Proven Tips to Unlock Equity for Your Second Property

Refinancing to release equity gives you access to the value built up in your home without selling it.

For homeowners in Bundoora, where the median house price sits at $905,000, this strategy can unlock substantial funds for a second property purchase. Whether you're targeting a rental investment or preparing to expand your portfolio, understanding how to access and deploy your equity is the foundation of the decision.

How Much Equity Can You Actually Access?

Most lenders allow you to borrow up to 80% of your property's value without paying lenders mortgage insurance. The usable equity is the difference between 80% of your current property value and your outstanding loan balance. Consider a scenario where your Bundoora home is valued at $905,000 and your remaining mortgage is $550,000. At 80% loan to value ratio, you can borrow up to $724,000, giving you $174,000 in available equity. After allowing for refinancing costs and a buffer for settlement, you'd have around $165,000 to deploy as a deposit on your next property.

That calculation changes if you're willing to pay lenders mortgage insurance to push beyond 80%, but the additional cost often outweighs the benefit unless you're purchasing in a rising market where timing matters more than minimising upfront expenses.

The Structure That Keeps Your Tax Position Clean

When you refinance to release equity for investment purposes, the way you structure the loan determines whether the interest remains tax deductible. You need a split loan facility where the original home loan portion remains separate from the equity release portion. The equity portion, used to fund the deposit and purchase costs of the investment property, becomes deductible against your rental income. The original loan portion, tied to your owner-occupied home, does not.

Mixing the two in a single loan account means you lose the ability to clearly demonstrate the investment purpose, and the Australian Taxation Office will disallow part of your deduction. We regularly see this error when clients refinance without considering the tax implications upfront, and it's difficult to unwind once the loan has settled.

Serviceability Hits Harder Than Equity Limits

Accessing equity is only half the equation. Lenders assess whether you can service both your existing home loan and the new investment loan together, and that's where many applicants find their plans constrained. Your income needs to cover both loans plus your living expenses, with lenders applying a buffer of around 3% above the current interest rate to stress-test your position.

In a scenario where you earn $140,000 annually and your current home loan repayment is $3,200 per month, adding a second investment loan of $450,000 increases your monthly commitment by roughly $2,600. Lenders calculate your disposable income after tax, existing debts, and living expenses, then apply their buffer. If your surplus doesn't cover the stressed repayment, the loan won't proceed regardless of how much equity you have. Reducing personal debt, consolidating credit cards, or bringing a partner onto the application can shift the calculation in your favour.

Why Bundoora Works for Equity-Funded Investment

Bundoora's proximity to La Trobe University and RMIT's Bundoora campus creates persistent rental demand, with a median house rent of $600 per week and a house yield of 3.38%. For investors extracting equity to fund a second property, targeting suburbs with structural rental drivers reduces vacancy risk and stabilises cash flow from day one.

The suburb's unit market offers a different equation, with a median unit price of $520,000 and a unit yield of 5.10%. Using the $165,000 in released equity as a 20% deposit positions you to purchase a unit outright without lenders mortgage insurance, and the higher yield offsets the negative gearing on your combined loan position. The trade-off is capital growth, where houses in Bundoora have historically outpaced units, but for investors prioritising cash flow and portfolio velocity, the unit market delivers.

The Timing Question: When to Refinance

Refinancing to access equity works when your property has grown in value since purchase or when you've reduced your loan balance enough to create a meaningful gap. If you purchased in Bundoora three years ago at the suburb's previous median and your property has appreciated in line with the City of Banyule's broader growth, you may now be sitting on $100,000 to $150,000 in accessible equity without making extra repayments.

Waiting for further growth sounds appealing, but it delays your entry into the investment property market and costs you rental income and compounding returns. The calculation depends on your income stability, your risk tolerance, and whether you're prepared to hold both properties through a flat or declining market. Timing the market perfectly is unlikely, but timing your refinance to coincide with a stable income period and competitive refinance rates improves your position materially.

What Lenders Actually Want to See

Lenders assess equity release applications differently to standard refinances. They want to see a clear investment strategy, evidence of rental demand in your target suburb, and proof that you've accounted for holding costs. A well-prepared application includes a rental appraisal for the intended purchase, a loan structure that separates deductible and non-deductible debt, and a buffer for interest rate rises.

For self-employed applicants or those with variable income, the assessment tightens further. Lenders may require two years of tax returns, a letter from your accountant, and evidence that your income is sustainable. If your most recent year shows a decline, even a temporary one, some lenders will assess you on the lower figure, reducing your borrowing capacity by tens of thousands. Structuring your application to emphasise consistency and providing context for any income variation makes the difference between approval and decline.

The Costs You Need to Account For

Refinancing to release equity isn't without expense. Discharge fees from your current lender, application fees for the new loan, valuation costs, and legal fees for settlement typically add $2,000 to $3,500 to the transaction. If your current loan has a fixed rate that hasn't expired, break costs can add thousands more depending on how far rates have moved since you locked in.

Those costs reduce your usable equity, so the $174,000 figure calculated earlier becomes $165,000 or less after accounting for the transaction. For clients refinancing to release equity, we model the net position after all costs to ensure the released funds justify the exercise. If you're only accessing $50,000 and paying $3,000 in costs, the percentage drag on your return is material. If you're accessing $150,000, the same costs become negligible in context.

How This Connects to Your Broader Portfolio Strategy

Using equity to fund a second property is the first step in a sequence. Once that property appreciates and you build equity in both assets, you can repeat the process to fund a third, then a fourth. The constraint is serviceability, not equity, so your income growth and debt reduction over time determine how quickly you can expand your property portfolio.

For Bundoora homeowners, the decision to refinance now or wait depends on whether your current equity position and income can support the second purchase without overextending. If the answer is yes, delaying costs you rental income and time in the market. If the answer is no, focusing on income growth, debt reduction, or a smaller first investment property adjusts the plan without abandoning it.
