Smart Ways to Use a Line of Credit for Debt Recycling

A line of credit gives you the most control over the debt recycling process.

Instead of redrawing from your home loan every time you make a payment, a line of credit sits alongside your existing mortgage and lets you draw funds as your non-deductible debt reduces. This keeps your non-deductible and deductible debt completely separate from the start, which makes record-keeping cleaner and ATO compliance straightforward. You draw only what you need, when you need it, and every dollar drawn is tied directly to an investment purpose.

Why a Line of Credit Works for Debt Recycling

A line of credit is a separate loan facility secured against your property that lets you access funds up to an approved limit without needing to reapply each time. You only pay interest on the amount you draw, not the full limit. This structure is designed for flexibility, which makes it well-suited to debt recycling where you're making regular but irregular draws as your non-deductible debt reduces.

When you make extra repayments on your home loan, that equity becomes available to redraw. Instead of accessing it through a redraw facility, which can mix deductible and non-deductible funds, you draw from the line of credit to invest. The line of credit balance increases as you draw funds, and the interest on that balance becomes tax deductible because the funds are used for income-producing investments.

Consider a homeowner in Doncaster with a home loan balance of $420,000. They set up a line of credit with a $100,000 limit. Over the course of a year, they make $18,000 in extra repayments on their home loan. Instead of redrawing those funds, they draw $18,000 from the line of credit and invest it into a diversified share portfolio. The interest on that $18,000 is now deductible, while the home loan balance continues to reduce. The two debt components remain separate, and the trail is clear.

How the Structure Protects Your Records

The line of credit creates a clean boundary between deductible and non-deductible debt. Every draw is documented, every dollar has a clear investment purpose, and there's no risk of accidentally contaminating the facility by using it for personal expenses. This separation is critical if the ATO ever requests evidence of how the borrowed funds were used.

Unlike a redraw facility, where funds can be withdrawn for any purpose and the loan history can become blurred, a line of credit is typically set up with the explicit purpose of funding investments. You don't use it to pay for renovations, holidays, or school fees. It's quarantined for investment loans only. That discipline protects the deductibility of the interest and makes tax time far less complicated.

In our experience, clients who use a line of credit structure spend less time assembling paperwork and more time focused on the investment itself. The facility does the heavy lifting when it comes to traceability.

What This Means for Cashflow

Because a line of credit only charges interest on the drawn balance, your repayments increase gradually as you draw more funds. This gives you control over how quickly you recycle debt. If your cashflow is tight in a particular month, you can pause draws. If you receive a bonus or tax refund, you can accelerate both your home loan repayments and your line of credit draws.

The interest on the line of credit is typically capitalised or paid as interest-only, which keeps your repayments lower than a principal-and-interest loan. That frees up cashflow to continue paying down your non-deductible home loan, which is where you want to direct the bulk of your repayments. The investment income from your portfolio, combined with the tax deduction on the line of credit interest, helps offset the cost of holding the facility.

For someone in Brighton with a marginal tax rate of 39%, the after-tax cost of borrowing on a line of credit is significantly lower than the headline rate. If the line of credit charges interest at current variable rates, the effective cost after claiming the deduction is notably reduced. That margin makes the strategy viable even when investment returns are modest in the short term.

Accessing the Facility as Your Equity Grows

As you pay down your home loan, your available equity increases. The line of credit limit can be set based on your initial equity position, and you draw against it progressively. Some lenders allow you to increase the limit over time as your property value rises or your loan balance reduces, but that's not essential. You can work within a fixed limit and draw only what your strategy requires.

The key is to match your draws to the reduction in your non-deductible debt. If you've paid off $25,000 of your home loan, you can draw up to $25,000 from the line of credit to invest. You're not creating new debt, you're converting existing debt from non-deductible to deductible. The total amount you owe doesn't change, but the structure and tax treatment do.

This approach suits homeowners who prefer a measured, methodical approach to debt recycling rather than recycling a lump sum upfront. It also suits clients who want to dollar-cost average into their investment portfolio rather than timing the market with a single entry point.

Comparing a Line of Credit to a Split Loan

A split loan structure is another option for debt recycling, where you split your home loan into two portions: one for non-deductible debt and one for investment debt. As you pay down the non-deductible portion, you increase the investment portion and use those funds to invest. This can work well, but it lacks the flexibility of a line of credit.

With a split loan, you need to coordinate with your lender each time you want to shift funds from one split to the other. The process can be slower, and some lenders charge fees for making adjustments. A line of credit, by contrast, is available on demand. You log into your account, transfer the funds, and invest. No approvals, no delays.

The trade-off is that a line of credit typically carries a slightly higher interest rate than a standard home loan. For Melbourne clients with strong cashflow and a clear investment plan, that difference is often worth the flexibility and simplicity. For clients who prefer a set-and-forget approach, a split loan might be more appropriate. The choice depends on how hands-on you want to be with the implementation of your strategy.

Structuring the Facility with Your Lender

Not all lenders offer line of credit products, and those that do have different criteria around loan-to-value ratios, credit limits, and documentation. You'll need enough equity in your property to support both your existing home loan and the line of credit facility. Most lenders will lend up to 80% of your property value without requiring lenders mortgage insurance, though some will go higher for the right client.

The application process involves providing evidence of income, assets, liabilities, and your intended use of the facility. Because the line of credit is secured against your home, the lender will assess your ability to service both the home loan and the line of credit simultaneously. This is where working with a broker who understands accessing finance for debt recycling becomes useful. The wrong lender or the wrong loan structure can limit your options or increase your costs unnecessarily.

You'll also need to decide whether to capitalise the interest on the line of credit or make regular interest payments. Capitalising interest means the interest charges are added to the drawn balance, which increases the amount you owe over time but keeps your cashflow intact. Paying interest separately keeps the balance stable but requires more monthly cashflow. Both approaches are valid, and the right choice depends on your income, tax position, and risk tolerance.

What Happens When You Want to Refinance

A line of credit is portable in some cases, but not always. If you decide to refinance your home loan to a different lender, you'll need to check whether the new lender offers a line of credit product and whether they're willing to replicate the structure. Some lenders will take on an existing line of credit as part of a refinance package. Others won't, which means you'd need to close the facility and restructure your debt recycling approach.

This is one reason it's worth setting up the line of credit with a lender who offers competitive rates and solid long-term support. Switching lenders mid-strategy can disrupt your momentum and create additional costs. If you're already considering a refinance, it's worth having that conversation before you establish the line of credit so you can build the structure with the right lender from the start.

For clients who are already repeat recyclers, the line of credit becomes a long-term tool rather than a one-off arrangement. You continue using it as your home loan reduces and your investment portfolio grows. Over time, the facility becomes central to how you manage debt and build wealth.

Setting Up for Long-Term Wealth Building

The advantage of using a line of credit for debt recycling is that it scales with your financial position. As your property value increases and your home loan reduces, you can continue to draw from the facility and invest. The process becomes repeatable, and the benefits compound. Every dollar of non-deductible debt you convert becomes a dollar of deductible debt, and every dollar invested has the potential to generate income and capital growth.

This structure works particularly well for Melbourne homeowners in suburbs where property values are stable or rising, such as Camberwell, Glen Waverley, or Essendon. The equity in your home grows over time, which increases your capacity to recycle debt without taking on additional risk. The line of credit gives you the mechanism to access that equity in a controlled, tax-effective way.

The strategy isn't about borrowing more. It's about borrowing smarter. The line of credit is the tool that makes that possible.
