Beginner's Guide to Refinancing & Accessing Equity

Refinancing to Access Equity Works Like Taking Out a Larger Loan

You refinance your mortgage and borrow against the value your property has gained. The lender reassesses what your home is worth, calculates how much equity you hold, and lets you access a portion of that as cash. That cash can fund a business, pay for equipment, or cover startup costs without needing a separate business loan at a higher rate.

Most lenders will allow you to borrow up to 80% of your property's current value without paying lenders mortgage insurance. If your home is now valued higher than when you first bought it, and you've paid down some of the loan, the gap between what you owe and what you can borrow is your usable equity. Consider an educator who purchased a property several years ago and has since paid down the mortgage while the property value has increased. They owe $320,000 on a home now valued at $550,000. At 80% of the property's value, they could borrow up to $440,000. Subtracting what they owe leaves $120,000 in accessible equity. They refinance, take $80,000 to invest in a tutoring business, and roll the rest back into the mortgage. The new loan sits at $400,000, and they now have capital to get the business off the ground without touching their savings or applying for unsecured finance at double the interest rate.

When Refinancing Makes Sense and When It Doesn't

Refinancing to access equity works when the cost of refinancing is lower than the cost of borrowing that money another way. If you're paying 6.5% on your current mortgage and a business loan would cost 9% or more, refinancing and drawing equity at the lower rate makes sense. You're also consolidating debt into one repayment instead of managing multiple loans.

It doesn't make sense if you're locked into a fixed rate period with significant break costs, or if your property hasn't gained enough value to give you the equity you need. Refinancing also resets the loan term unless you structure it carefully. If you've already paid off ten years of a thirty-year mortgage, refinancing into a new thirty-year term means you're paying interest for longer. You can avoid this by keeping the loan term aligned with your original end date, but you need to specify that upfront. We regularly see educators assume the term will stay the same, only to realise later they've added years to their mortgage.

How Lenders Assess Your Business When You Refinance

Lenders don't treat equity release for a business the same way they treat refinancing for debt consolidation or home improvements. They want to know what the money is for, and they assess serviceability based on your current income, not projected business earnings. If you're still working as an educator and the business is a side venture, your teaching income covers the loan. If you're planning to leave teaching and rely on business income, the lender will want to see that the business is already generating consistent revenue, usually for at least two years.

In our experience, the cleanest way to structure this is to keep your teaching role while the business establishes itself. Your employment income satisfies the lender's serviceability requirements, and you can use the equity to fund the business without needing to prove business income or provide profit and loss statements. Once the business is generating stable income, you can adjust your work arrangements without affecting the loan.

The Valuation Determines How Much You Can Borrow

The lender orders a property valuation as part of the refinance application. If the valuation comes in lower than you expected, the amount of equity you can access shrinks. Valuations are based on recent sales of comparable properties in your area, and they can vary between lenders. A property you think is worth $600,000 might be valued at $570,000, which changes the numbers.

You can't control the valuation, but you can make sure the property is presented well when the valuer visits. Small things like fresh paint, tidy gardens, and completed repairs can influence the outcome. If the valuation comes in too low and you disagree with it, some lenders will allow you to request a second valuation, though you'll usually pay for it. If the valuation still doesn't support the loan amount you need, you'll either need to borrow less or wait until the property gains more value.

Fixed Rate Periods and Refinancing Costs

If you're currently on a fixed rate, refinancing before the fixed period ends will trigger break costs. These can run into thousands of dollars, depending on how much time is left on the fixed term and how much rates have moved since you locked in. Some educators coming off a fixed rate find that refinancing to access equity coincides with their fixed rate expiry, which avoids break costs entirely.

If your fixed rate period is ending soon, it's worth timing the refinance to align with that expiry so you're not paying to exit early. If you're still locked in and the break costs are significant, you'll need to weigh those costs against the benefit of accessing the equity now versus waiting. In some cases, it makes sense to wait. In others, particularly if you're accessing equity to fund a time-sensitive business opportunity, the break costs are worth paying.

Structuring the New Loan With an Offset or Redraw

Once you refinance and access the equity, the way you structure the new loan affects how you manage the debt. An offset account lets you park any business income or savings against the loan balance, reducing the interest you pay without locking the money away. A redraw facility lets you pull money back out if you need it, but not all lenders offer the same flexibility, and some charge fees for redraws.

If you're using the equity for a business and expect irregular income or lump sum payments, an offset account gives you more control. You can deposit business income into the offset, reduce your interest, and still access the money when you need it. Redraw works if you're confident you won't need to pull the money out frequently, but it's less flexible. When refinancing, make sure the loan structure matches how you plan to manage the business funds. Not every loan product offers both features, and switching later can mean refinancing again.

Tax Implications When You Use Equity for Business

The portion of your mortgage that relates to the equity you've accessed for business purposes is usually tax-deductible, while the portion that relates to your home isn't. This means you need to keep the business debt separate in your loan structure, either by splitting the loan into two accounts or keeping detailed records of how the funds were used.

Most accountants recommend splitting the loan so the business portion sits in its own account. That way, the interest on that portion is clearly linked to the business, and you can claim it at tax time without needing to calculate the split manually. If you don't split the loan and the funds get mixed, proving what portion of the interest is deductible becomes harder. It's worth discussing the structure with your accountant before you refinance, because changing it later means refinancing again. For more detail on how this works, debt recycling operates on a similar principle, where the deductibility of interest depends on how the borrowed funds are used.

Serviceability and How Much You Can Actually Borrow

Lenders calculate serviceability based on your income, expenses, and existing debts. Even if you have $120,000 in equity, the lender won't let you access all of it if your income can't service the larger loan. They test your ability to repay at a higher interest rate than you'll actually pay, usually adding a buffer of around 3%. If you're borrowing $400,000 and your current rate is 6.2%, they'll assess whether you can afford repayments at 9.2%.

This is where your income as an educator matters. Teaching salaries are seen as stable and reliable, which helps with serviceability. If you have other debts like a car loan or credit card, those reduce how much you can borrow. Paying off or consolidating those debts before you apply can improve your borrowing capacity. We regularly see educators surprised by how much their credit card limit affects serviceability, even if they don't carry a balance. Lenders assume you could max out the card at any time, so they factor the full limit into your expenses. Reducing or closing the card before you apply can increase how much equity you can access. For a broader look at how lenders assess what you can borrow, borrowing capacity covers the key factors that influence the outcome.

The Refinance Application and What It Involves

The refinance process involves a full loan application, similar to when you first bought the property. You'll need to provide payslips, tax returns, bank statements, and details about what you're using the equity for. If you're accessing funds for a business, the lender will ask for a letter or statement explaining the purpose. You don't need a full business plan in most cases, but you do need to show that the funds are going toward a legitimate business expense, not personal spending.

The application usually takes two to four weeks from submission to settlement, depending on how quickly the valuation is completed and how responsive the lender is. You'll also need to account for discharge fees from your current lender, application fees for the new lender, and legal costs for settling the new loan. These can add up to a few thousand dollars, so factor them into your decision. Some lenders offer cashback incentives when you refinance, which can offset these costs, but the cashback shouldn't be the main reason you choose a lender. The loan structure, interest rate, and features matter more in the long term.
