Everything You Need to Know About Refinancing for Equity

Refinancing to access equity means you replace your current home loan with a new one that has a higher loan amount, releasing the difference as cash you can use for investment purposes.

Property owners across Australia sit on substantial equity without realising how accessible it is. Your lender will typically allow you to borrow up to 80% of your property's current value, minus what you still owe. That difference can fund a deposit on an investment property, build a granny flat, or cover other investment costs, all while consolidating the debt into your mortgage at a lower interest rate than most other forms of borrowing.

How Equity Release Through Refinancing Works

You borrow against the increased value of your property. If your home is worth more now than when you bought it, or you have paid down a portion of your loan, that creates usable equity. The refinance application lets you access that equity in cash while resetting your loan terms, and often moving to a lower rate or a lender with features that suit your current situation.

Consider a property owner in western Sydney whose home was valued at $650,000 when they took out their mortgage. They still owe $420,000. The property is now worth $780,000. At 80% lending, they can borrow up to $624,000. After paying out the existing $420,000, they would have access to $204,000 in equity, minus refinancing costs. That amount could fund a deposit and costs for an investment property, or cover the full build cost of a granny flat on the existing land.

The refinance process involves a property valuation, a loan review of your income and expenses, and an application with either your current lender or a new one. Most lenders take two to four weeks to settle a refinance once the application is lodged.

Why Refinance Instead of a Top-Up or Second Mortgage

Refinancing consolidates everything into one loan at a single interest rate. A top-up with your existing lender might be faster, but you are stuck with your current rate and loan terms. If a lower rate is available elsewhere, or your current lender does not offer the offset account or redraw flexibility you need, refinancing gives you the chance to improve your loan structure at the same time you access equity.

Second mortgages or equity loans typically come with higher interest rates and shorter repayment terms, which can strain cashflow. Refinancing into a single mortgage means one repayment, one interest rate, and the option to spread that repayment over a longer term if needed to improve cashflow.

When Refinancing to Access Equity Makes Sense

You have a clear investment purpose and the income to service the higher loan amount. Lenders assess your ability to repay based on your current income, expenses, and existing debts. Accessing equity increases your loan, which increases your repayment. If your income supports that comfortably, and you are using the funds to acquire an income-producing asset or build something that adds value, the strategy holds up.

In our experience, property owners refinancing for a granny flat as an investment often see the rental income from that structure offset much of the increased repayment, while also adding long-term value to the property. Similarly, using equity to fund a deposit on an investment property means the rent from that property contributes to covering the loan costs.

Refinancing also makes sense if your fixed rate period is ending and you are coming off a fixed rate onto a higher variable rate. You can access equity and lock in a new rate at the same time, rather than drifting onto your lender's standard variable product.

How Much Equity Can You Access

Most lenders will lend up to 80% of your property's current value without requiring lenders mortgage insurance. If you borrow more than 80%, you will pay insurance, which adds thousands to your costs depending on the loan amount. Staying at or below 80% keeps your refinance cleaner and avoids that extra expense.

Your available equity is calculated as 80% of your property's value, minus your current loan balance and any refinancing costs. If you owe $300,000 on a property now valued at $700,000, you can borrow up to $560,000. After paying out the $300,000, you would have roughly $255,000 available, after accounting for discharge fees, application fees, and valuation costs, which usually sit between $2,000 and $5,000.

A loan health check will show you exactly where your equity sits and whether accessing it now makes sense based on current lending criteria and your financial position.

Fixed or Variable After You Refinance

You can switch to a fixed interest rate, variable interest rate, or split the loan between both. A fixed rate locks in your repayment for one to five years, which helps with budgeting if you are taking on a higher loan amount. A variable rate gives you access to an offset account and unlimited extra repayments, which can reduce your interest costs over time if you have surplus income or irregular cashflow.

Splitting the loan lets you lock in part of your borrowing while keeping flexibility on the rest. Many property investors split their loan so the portion used for investment purposes sits on a variable rate with offset, while the portion tied to their home sits on a fixed rate for stability.

Your choice depends on your risk tolerance, cashflow, and whether you expect rates to move. If you want certainty, fix. If you want flexibility and the ability to reduce your loan faster, stay variable or split.

The Refinance Application Process

You will need to provide income verification, recent loan statements, and details of your assets and liabilities. Lenders will order a property valuation to confirm the current value of your home. If the valuation comes in lower than expected, your available equity drops, and you may need to adjust your plans.

The application itself takes one to two weeks for assessment, then another one to two weeks for settlement once approved. During that time, you will receive a discharge authority from your current lender, which your new lender uses to pay out the existing loan. The equity you are accessing is released at settlement, either paid directly to you or to a third party such as a builder or conveyancer, depending on how you are using the funds.

If you are refinancing to fund a construction loan for a granny flat, the equity portion can be drawn down progressively as the build reaches each stage, rather than all at once.

Costs Involved in Refinancing

Discharge fees from your current lender usually sit between $150 and $500. Application fees with the new lender range from $0 to $1,000 depending on the product. Valuation fees are typically $200 to $600. Settlement fees and legal costs add another $1,000 to $2,000. If you are breaking a fixed rate early, break costs can run into thousands depending on how much time is left and how far rates have moved since you fixed.

Some lenders offer cashback incentives or waive application fees to attract refinance customers, which can offset part of these costs. Those offers are worth considering, but only if the underlying interest rate and loan features suit your needs. A cashback of $2,000 does not help if the rate is 0.20% higher than the next lowest option.

Refinancing to access equity is not about chasing a lower rate for its own sake. It is about using the value sitting in your property to fund something that generates income, builds wealth, or solves a problem you are facing right now. If your home has increased in value, or you have been paying down your loan steadily, that equity is available. The refinance process puts it to work.
