Do you know how to use your equity to buy again?

Your equity is working capital, not a trophy.

If you bought in Melbourne five years ago, you're likely sitting on substantial growth. That equity can fund a second property purchase without liquidating your first asset. The mechanism is a cash out refinance that increases your loan amount and releases the difference as usable capital. The structure matters because your loan to value ratio determines how much you can access, and how quickly lenders will approve it.

What Refinancing to Release Equity Actually Involves

Refinancing to release equity means increasing your home loan beyond what you currently owe and receiving the difference in cash. Lenders assess your available equity by calculating your property's current value against your outstanding loan, then allow you to borrow up to 80% of that value in most cases, or 90% if you pay lender's mortgage insurance. The released funds can be used for any purpose, but using them as a deposit on an investment property often creates the most leverage.

Consider a professional who purchased in Kew for $950,000 with a 20% deposit and still owes $680,000. The property is now valued at $1,200,000. At 80% LVR, they can borrow up to $960,000, which means they can release $280,000 in equity. After setting aside $30,000 for stamp duty and settlement costs on the next purchase, they have $250,000 available as a deposit. That positions them to acquire a $1,000,000 investment property with a 25% deposit, keeping them under 80% LVR on the second property and avoiding mortgage insurance entirely.

How Lenders Calculate Your Available Equity

Your equity position is the difference between your property's current market value and what you owe. Lenders then apply a maximum LVR, typically 80%, to determine how much they'll lend in total. Subtract your current loan balance from that figure and you'll know what you can access. Valuations are ordered by the lender and conducted by an independent valuer, so your estimate of property value needs to align with market evidence, not aspiration.

If your property has increased materially in value since purchase, equity release can happen faster than saving a second deposit from income. Melbourne's inner and middle-ring suburbs have seen consistent capital growth, particularly in areas like Hawthorn, Richmond, and Brunswick, where median values have appreciated significantly over the past decade. That growth converts directly into borrowing capacity when structured through a refinance.

The Borrowing Capacity Test You Need to Pass

Accessing equity is only half the equation. You also need to service the debt. Lenders assess your income, existing liabilities, and living expenses to determine whether you can afford both the increased home loan and the new investment loan simultaneously. This is where professionals with stable income and low personal debt have an advantage. Lenders apply a buffer rate, usually 3% above the actual interest rate, to stress-test your repayment capacity. If your income covers both loans at that buffered rate, approval follows.

In a scenario where a borrower earns $180,000 annually, has no car loan or credit card debt, and low living expenses, they can typically service around $1,500,000 in total lending. If they already owe $680,000 on their home, that leaves approximately $820,000 in additional borrowing capacity. That's more than enough to fund the equity release and the second property purchase. Income structure matters as well. PAYG income is assessed at 100%, while bonus and commission income may be assessed at 80% or require a two-year average depending on the lender.

Why the Second Property Should Be an Investment, Not an Upgrade

Using equity to upgrade your primary residence locks capital into a non-income-producing asset and increases your non-deductible debt. Using it to acquire an investment property creates rental income, potential capital growth, and tax deductions on the interest. The loan used to release equity becomes tax-deductible when the funds are used for investment purposes, which reduces your taxable income. If you borrow $280,000 to fund an investment deposit and that loan costs $18,000 per year in interest, that $18,000 is deductible against your income, not just the rental income from the new property.

Melbourne professionals in higher tax brackets benefit most from this structure because the deduction offsets income taxed at marginal rates of 37% or 45%. The rental income from the second property also contributes to serviceability, making it easier to hold both loans long-term. Over time, both properties appreciate, compounding your wealth position without requiring ongoing capital injections. This is how equity becomes leverage, and leverage becomes portfolio growth.

What Happens If Your Current Lender Won't Release Enough

Not all lenders assess property value or serviceability the same way. If your current lender values your property conservatively or applies restrictive serviceability criteria, switching lenders during the refinance can unlock more equity. Some lenders use automated valuation models that undervalue unique or tightly held properties. Others apply stricter expense assumptions that reduce your borrowing capacity. A mortgage broker with access to multiple lenders can identify which one will give you the highest valuation and the most favourable serviceability assessment.

In our experience, professionals with complex income structures, such as those with bonuses, overtime, or salary packaging, benefit most from lender comparison. One lender may assess 80% of bonus income while another assesses 100%, and that difference can translate to tens of thousands in additional borrowing capacity. Refinancing also lets you review loan features, interest rates, and offset account structures to ensure the debt is working as hard as your equity.

When Not to Extract Equity

Releasing equity makes sense when you have a productive use for the capital and the income to service the increased debt. It doesn't make sense if your borrowing capacity is already stretched, if the second property won't generate sufficient rental return, or if the equity release pushes your LVR above 80% without a clear financial upside. Paying lender's mortgage insurance to access equity is sometimes justified, but only if the opportunity cost of waiting outweighs the insurance premium.

If you're considering a construction loan or a property that requires significant renovation, the equity release needs to account for those additional costs, not just the purchase price. Borrowing to your maximum capacity also removes flexibility if interest rates rise or your income changes. The sharper play is to retain a buffer between what you can borrow and what you do borrow, so your position remains resilient under different conditions.
