What Is Home Equity and Why Does It Matter When Refinancing?
Home equity is the portion of your property you actually own outright, calculated by subtracting what you owe on your mortgage from your property's current value. If your Malvern home is worth $1.8 million and you owe $900,000, you have $900,000 in equity. This number determines what you can do when refinancing, from accessing a lower rate to funding your next investment or renovation.
Most lenders require you to keep at least 20% equity in your property after refinancing, which means you can typically access up to 80% of your property's value. The difference between what you owe and that 80% threshold is what you can release or borrow against. Understanding this calculation lets you know whether refinancing makes sense right now or whether you need to wait for your property value to increase or your loan balance to drop.
How to Calculate Your Current Equity Position
Start with your property's current market value. In Malvern, where values have shifted considerably over recent years due to demand for period homes near High Street and the train line, your property may be worth significantly more than when you purchased. Subtract your outstanding loan balance from that value, then divide the result by the property value and multiply by 100 to get your equity percentage.
Consider a buyer who purchased a three-bedroom Edwardian in Malvern several years ago. At purchase, they borrowed 80% of the value with a $200,000 deposit. They've since paid down the loan to $850,000, and the property is now valued around the suburb's median for that property type. Their equity sits at roughly 50%, giving them significant room to refinance and access funds without needing to pay lenders mortgage insurance again. They could release equity to fund an investment property deposit or renovate the kitchen and bathroom, while still keeping their loan-to-value ratio comfortably under 80%.

What Affects How Much Equity You Can Access
Your borrowing capacity plays a role. Even if you have 60% equity in your home, a lender will assess whether you can service a larger loan based on your income, expenses, and existing debts. Someone with high credit card limits or other ongoing commitments may not be able to access the full amount their equity theoretically allows.
The lender's valuation also determines the outcome. If you believe your home is worth $2 million but the lender's valuer assesses it at $1.85 million, that $150,000 difference directly reduces the equity you can access. In areas like Malvern, where street appeal and period features can create valuation variation, it's worth understanding what recent comparable sales show before you apply. A loan health check can help you understand whether your current loan structure is making the most of your equity position.
Using Equity to Refinance to a Lower Rate
If your fixed rate period is ending and you have built equity, refinancing gives you leverage to negotiate. Lenders view borrowers with higher equity as lower risk, which can open access to sharper rates or offset accounts and redraw features that weren't available on your original loan. The larger your equity buffer, the more options you typically have.
Refinancing to access a lower rate while keeping your loan amount the same means your equity position stays unchanged or improves as you pay down the principal faster. You're not increasing your debt, just reducing what you pay in interest over time. This approach works well if your main goal is to reduce loan costs rather than access funds.
Releasing Equity for Your Next Property Purchase
Malvern homeowners often use equity to fund deposits on investment properties or to upsize within the area. If you have $700,000 in accessible equity and want to purchase an investment property in Carnegie or Camberwell, you can use that equity as security without selling your current home. The lender takes a mortgage over both properties, and you service both loans from your income.
In a scenario like this, your Malvern property acts as the anchor. You refinance your existing loan to release funds for the deposit and purchase costs on the second property, then take out a separate investment loan secured against the new property. Structuring it correctly means you can claim the interest on the investment loan as a tax deduction while keeping your owner-occupied loan separate. This is where working with a mortgage broker in Malvern helps, as the loan structure and documentation need to be set up properly from the start.
When Refinancing to Access Equity Doesn't Make Sense
If you only have 15% equity, refinancing to release funds isn't an option without paying lenders mortgage insurance again, which can add thousands to your loan. In that situation, it's usually worth waiting until you've paid down more of the principal or until your property value increases enough to push you above the 20% threshold.
Refinancing also doesn't make sense if the cost of exiting your current loan outweighs what you'll save or access. Break costs on fixed loans, discharge fees, and application fees for the new loan all add up. If you're refinancing purely to access equity and those costs eat into what you're releasing, you may be shifting debt around without gaining anything meaningful. Run the numbers before you commit, or ask someone to run them for you.
How Lenders Value Your Malvern Property
Lenders use their own panel valuers, not real estate agents, to assess your property. The valuer considers recent sales of comparable properties in Malvern, the land size, the condition of the home, and any improvements you've made. A renovated period home near Glenferrie Road or Central Park will typically attract a higher valuation than an unrenovated equivalent, but the valuer won't give full credit for overcapitalisation.
If you've renovated recently, provide invoices and before-and-after photos with your refinance application. This documentation can support a higher valuation, especially if the work included structural improvements, kitchen or bathroom updates, or landscaping. The valuer still makes the final call, but giving them clear evidence of what's been done helps ensure they don't undervalue the property based on outdated sales data.
What Happens If You Don't Have Enough Equity Yet
If your equity sits below 20%, you can still refinance, but your options narrow. Some lenders will refinance at higher loan-to-value ratios, but you'll pay lenders mortgage insurance and likely face higher interest rates. Alternatively, you can wait and focus on paying down the loan faster or making extra repayments into an offset account, which reduces the interest you pay and builds equity more quickly.
Another option is to wait for property values to rise. Malvern's proximity to the city, the quality of local schools, and the appeal of the heritage housing stock have historically supported value growth, though no one can predict short-term movements. If you're not in a rush to access equity, letting time and market conditions work in your favour can be the most cost-effective approach.

Frequently Asked Questions
How do I calculate the equity in my Malvern home?
Subtract your outstanding loan balance from your property's current market value. Divide the result by the property value and multiply by 100 to get your equity percentage. For example, if your home is worth $1.8 million and you owe $900,000, you have 50% equity.
How much equity do I need to refinance without paying lenders mortgage insurance?
You typically need at least 20% equity to refinance without paying lenders mortgage insurance. This means your loan balance should be no more than 80% of your property's current value.
Can I use equity in my Malvern home to buy an investment property?
Yes, if you have sufficient equity and borrowing capacity. Lenders can release equity from your Malvern home to fund a deposit on an investment property, with both properties secured against the loans. The loan structure needs to be set up correctly to maximise tax benefits.
What if the lender's valuation is lower than I expected?
The lender's valuation directly affects how much equity you can access. If the valuation comes in lower than expected, your accessible equity reduces accordingly. Providing evidence of recent renovations or improvements can sometimes support a higher valuation.
Should I refinance if I only have 15% equity in my home?
Refinancing with less than 20% equity usually means paying lenders mortgage insurance again, which can add significant cost. In most cases, it's worth waiting until you've built more equity through loan repayments or property value growth.
