Do you know how to use home equity for a second property?

Refinancing to Access Equity for a Second Property

You can access equity in your existing home by refinancing your mortgage to increase your loan amount, giving you cash to fund a deposit on a second property. The lender reassesses your property's current value and your capacity to service the larger loan, then releases the difference between what you owe and what you can borrow based on their lending criteria.

This approach works when your property has increased in value or you've paid down your loan enough to create usable equity. Lenders typically allow you to borrow up to 80% of your property's current value without needing lender's mortgage insurance, though some will go higher depending on your financial position. If your home is valued higher than when you purchased it, or you've been making repayments for several years, you may have built up equity that can be used as a deposit elsewhere.

Consider a homeowner in Werribee who purchased a property years ago and has seen strong capital growth in the area. Their home is now valued higher, and they've reduced their loan balance through regular repayments. By refinancing, they can borrow against that increased value to fund a deposit on an investment property in Point Cook, where new developments and infrastructure growth continue to attract tenants. The refinance increases their home loan, but the rental income from the second property contributes to servicing both loans.

How Much Equity Can You Actually Use?

Your usable equity is the difference between your property's current market value and 80% of that value, minus what you still owe on your home loan. Lenders calculate this to determine how much additional borrowing they'll approve, and the amount you can access depends heavily on your income, existing debts, and overall capacity to service the increased loan.

If you want to borrow more than 80% of your property's value, you'll typically need to pay lender's mortgage insurance, which adds to your upfront costs. Staying within the 80% threshold keeps your borrowing costs lower and makes the refinance process more straightforward. Your available equity also needs to cover not just the deposit on the second property, but also stamp duty, conveyancing fees, and any other settlement costs associated with the purchase.

In our experience, borrowers often overestimate how much they can access because they focus on their property's total value rather than the lending cap. A property valued at $600,000 with a remaining loan balance of $350,000 gives you access to roughly $130,000 in equity if you stay within the 80% loan-to-value ratio. That might be enough for a deposit and costs on a second property, but it depends on what you're buying and where.

What Lenders Assess When You Refinance for Equity

Lenders assess your income, living expenses, and existing debts to confirm you can service both your current home loan and the additional amount you want to borrow. They apply serviceability buffers and assess your capacity at a higher interest rate than the one you'll actually pay, which means your borrowing capacity may be lower than expected even if you have sufficient equity.

Your employment type, credit history, and the property you're buying all influence approval. If you're purchasing an investment property, lenders will consider a portion of the expected rental income when calculating your serviceability, but they don't count the full amount. Typically, they'll assess around 80% of the rental income to account for vacancy periods and maintenance costs.

If you have other debts such as car loans, personal loans, or credit card limits, these reduce your borrowing capacity. Lenders assess credit card limits as if they're fully drawn, even if you pay them off each month. Closing unused accounts or reducing limits before applying can improve your serviceability and increase the amount you're approved to borrow.

Choosing Between Refinancing Your Current Lender or Switching

You can access equity by refinancing with your existing lender or by switching to a new one, and each option has different costs and timeframes. Staying with your current lender can be quicker and may involve fewer upfront fees, but switching to a new lender can give you access to lower rates or more flexible loan features that reduce your ongoing interest costs.

If you refinance to a new lender, you'll typically pay application fees, valuation fees, and potentially discharge fees from your current lender. These costs need to be weighed against the potential savings from a lower interest rate or the benefit of accessing equity that your current lender won't approve. Some lenders also offer cashback incentives or waive certain fees to attract refinance customers, which can offset some of the switching costs.

Staying with your current lender makes sense if they're willing to approve the additional borrowing at a competitive rate and you're already on a loan structure that suits your needs. If your current loan has a high interest rate or restrictive features, switching can give you better flexibility and lower repayments across both properties.

How Refinancing Affects Your Tax Position

The interest on the additional borrowing used to purchase an investment property is generally tax-deductible, but only if the funds are directly used for that investment purpose. Keeping the equity release portion separate from your existing home loan makes it easier to track and claim the deduction, and most brokers recommend splitting your loans to maintain clear records.

If you increase your home loan and use part of the funds for personal expenses or to pay down non-deductible debt, that portion won't be tax-deductible. Lenders and accountants both recommend structuring your refinance so the investment-related borrowing is clearly separated, either through a split loan or by setting up a new loan account entirely.

We regularly see borrowers who want to access equity for multiple purposes, such as buying an investment property and renovating their current home. In those cases, splitting the additional borrowing into separate accounts allows you to claim the investment portion while keeping the renovation borrowing separate. Your accountant can advise on the most effective structure for your situation, but the key is ensuring the funds are used for the purpose you're claiming.

What Happens If Your Equity Position Changes?

Property values fluctuate, and a decline in your home's value can reduce your available equity or affect your ability to refinance. Lenders base their approval on a current valuation, so if your property's value has dropped since you last checked, you may not have as much equity as you expected or you may need to provide a larger deposit from other sources.

If you've already refinanced and accessed equity, a drop in property values doesn't typically trigger any immediate action from your lender as long as you continue making repayments. However, it does limit your ability to access further equity in the future until values recover or you pay down more of your loan balance.

Market conditions across Victoria vary by location, and suburbs with strong infrastructure investment or population growth tend to hold value more consistently than areas with oversupply or declining demand. If you're relying on equity growth to fund your second property purchase, timing your refinance to align with a strong market period can make a significant difference to how much you can access.

Using Equity for Investment Properties Across Victoria

Victorian buyers often use equity from their primary residence in established suburbs to purchase investment properties in growth areas where entry prices are lower and rental demand is strong. Suburbs like Truganina, Point Cook, and Werribee continue to attract investors due to their proximity to Melbourne, improving infrastructure, and steady tenant demand.

Accessing equity allows you to enter the investment market without needing to save a full deposit from your income, which can take years depending on your financial position. The rental income from the second property contributes to loan repayments, and over time, both properties can benefit from capital growth while you build equity in each.

The approach works particularly well when your primary residence has experienced solid growth and you have stable employment that supports the increased borrowing. If you're considering an investment property in a specific location, understanding the local rental market, vacancy rates, and potential for future growth helps ensure the investment stacks up financially and that the rental income supports your overall serviceability.
