What is a line of credit home loan?

The direct answer

A line of credit home loan gives you an approved credit limit secured against your property that you can draw on as needed, similar to a credit card but at home loan rates. You only pay interest on the amount you have drawn, not the full limit. They are commonly used for renovations, investment, or as a financial buffer, but require discipline because the balance can grow if not managed.

How a line of credit works

A line of credit (LOC) is set up as a revolving credit facility. Once approved, you can draw funds up to your limit at any time, repay them, and draw again - the cycle repeats for the life of the facility. Unlike a standard home loan that reduces over time, the balance on a LOC can go up and down depending on your draws and repayments.

Interest is calculated daily on your outstanding balance, just like a home loan. If your limit is $200,000 and you have only drawn $80,000, you only pay interest on $80,000. The limit itself is secured against your property - typically your home equity. To access a LOC, lenders usually require at least 20% equity in the property.

Common uses for a line of credit

The most common uses are home renovations, where costs are staged and you draw as invoices arrive; funding an investment property deposit without fully refinancing; bridging business cash flow needs; and as an emergency financial buffer for self-employed borrowers with irregular income.

A LOC can also be used as part of an investment debt recycling strategy - drawing funds to invest in income-producing assets, converting non-deductible home loan debt into potentially deductible investment debt over time. This is a sophisticated strategy that requires careful advice from a financial adviser and accountant before implementing.

Advantages vs risks - flexibility comes at a cost

The main advantage of a LOC is genuine flexibility. You are not locked into drawing a set amount on a set date, and repayment terms are typically interest-only with no fixed end date. For disciplined borrowers with genuine variable funding needs, this is genuinely useful.

The risk is debt creep. Because there is no principal reduction requirement, borrowers can find themselves with an unchanged or growing balance years into having a line of credit. The interest rate on LOCs is often slightly higher than standard variable rates. And because the full limit counts against your borrowing capacity regardless of usage, it can limit your ability to borrow for other purposes down the track.

Line of credit vs offset account vs redraw - when each is better

A line of credit is a separate facility that can be set up against a property you already own. An offset account is linked to your existing home loan and reduces the interest you pay without you drawing funds. A redraw facility lets you access extra repayments you have made above the minimum on your current loan.

For most owner-occupiers who want flexibility, an offset account or redraw will achieve the same outcome at lower cost and without affecting borrowing capacity. A line of credit makes more sense for investors or business owners who need a genuinely separate facility, or who are using the funds for purposes that require clean separation from their main loan for tax or accounting reasons.

Common questions

Frequently asked questions

Does a line of credit affect my borrowing capacity?

Yes - lenders assess the full approved limit of a line of credit as a liability when calculating your borrowing capacity, regardless of how much you have actually drawn. A $200,000 LOC limit that you have only used $50,000 of will still reduce your borrowing capacity by the full $200,000 in the eyes of most lenders.

Is the interest on a line of credit tax deductible?

It depends on the purpose of the draw. If you use the line of credit to fund an income-producing investment (such as buying shares or an investment property), the interest on that portion is generally deductible. If you draw it for personal expenses or a holiday, it is not. Mixed-purpose LOCs require careful record-keeping to support any deduction claims - speak with your accountant.

Are there fees for drawing down on a line of credit?

Some lenders charge a draw-down fee each time you access funds, while others charge an annual facility fee regardless of usage. The fee structure varies significantly between lenders. Always factor these costs into your comparison - a LOC with higher fees may be more expensive than a standard loan with a redraw facility for occasional large draws.

What are the minimum repayment requirements on a line of credit?

Most lines of credit only require you to pay the interest charged each month, with no requirement to reduce the principal. This is what makes them flexible - but also what makes them risky. If you only ever pay the minimum, the balance never decreases and you will be paying interest forever. Disciplined borrowers set voluntary principal repayments above the interest minimum.
