Avoid These 3 Mistakes When Refinancing for Equity

Refinancing to pull equity from your home for an investment property is one of the more common ways to build a portfolio across Northern NSW.

The concept is simple enough: you borrow against the value your home has gained, use that as a deposit on a second property, and let rental income cover most of the new loan. But the execution is where people trip up. Lenders assess you differently when the purpose is investment, and the equity you think you have access to is often less than the amount you can actually borrow against.

Mistake 1: Assuming Your Equity Equals Your Usable Deposit

The equity in your home is the difference between what it's worth and what you owe. Usable equity is different.

Most lenders will let you borrow up to 80% of your property's value without paying Lenders Mortgage Insurance. If your home is valued at $600,000 and you owe $300,000, your equity is $300,000. But you can only borrow up to $480,000 (80% of $600,000), which means your usable equity is $180,000, not $300,000. That $180,000 still needs to cover your deposit, stamp duty, and other costs on the investment property.

Consider a scenario where someone in Lismore owns a home valued at $550,000 with $250,000 still owing. They want to buy an investment property in Ballina for around $650,000. Their equity is $300,000, but their usable equity at 80% is $190,000. After setting aside roughly $30,000 for stamp duty and costs, they have about $160,000 for a deposit. That's a 24% deposit on a $650,000 purchase, which keeps them under the 80% loan-to-value ratio on the new loan and avoids mortgage insurance on both properties.

If they'd assumed they could access the full $300,000, they would have started looking at properties outside their actual range and wasted weeks before a lender pulled them back to reality.

Mistake 2: Not Factoring in How Lenders Assess Rental Income

When you refinance your home loan to access equity for investment, the lender doesn't just look at your current income. They also assess your ability to service both your existing mortgage and the new investment loan.

Rental income helps, but lenders don't count all of it. Most will only factor in 80% of the expected rent to account for vacancies and maintenance. If the property you're buying is expected to rent for $500 a week, the lender will only use $400 of that in their serviceability calculation.

This catches people out when they assume the rent will cover the new loan repayments and their borrowing capacity stays the same. It doesn't. Your debt has increased, and even with rental income offsetting part of it, your serviceability shrinks. If you're already close to your borrowing limit, adding an investment loan can push you over, even if the investment property is positively geared on paper.

In our experience, borrowers in regional areas often underestimate how much buffer lenders require, especially if interest rates have climbed since they took out their original loan. A loan health check before you start looking at investment properties will show you exactly how much you can borrow and whether refinancing your current loan to a lower rate might improve your serviceability enough to make the investment stack up.

Mistake 3: Ignoring the Refinance Costs When Calculating Return

Refinancing isn't without cost, and those costs eat into the return on your investment property if you don't account for them upfront.

You'll typically pay for a property valuation on your existing home, discharge fees to exit your current loan, application fees with the new lender, and sometimes legal costs if there's a change in loan structure. These can add up to anywhere between $1,500 and $3,000 depending on your lender and the complexity of your situation.

If you're refinancing to access a lower interest rate at the same time, those costs might be worth it even without the investment property in the picture. But if your current loan already has a competitive rate and you're only refinancing to pull equity, you need to factor those costs into your investment budget. Spending $2,500 to access $180,000 in equity is reasonable. Spending $2,500 and then realising you're $5,000 short on your deposit because you didn't plan for settlement costs on the investment property is not.

We regularly see this with buyers around the Northern Rivers who've done all the right research on the investment property but haven't mapped out the full cost of the refinance itself. The result is either a last-minute scramble for additional funds or a delay in settlement that can cost you the property if the vendor isn't flexible.

How the Refinance Application Actually Works for Investment Equity

The application process for refinancing to access equity is similar to a standard home loan refinance, but the lender will want detail on the investment property you're planning to buy.

You'll need to provide a contract of sale or at minimum a clear indication of the property type, location, and expected purchase price. The lender will assess the investment property's rental potential using a third-party rental appraisal or their own internal data. They'll also want to see your current income, expenses, and any other debts to confirm you can service both loans.

If your fixed rate period is ending on your current home loan, that's often a natural time to refinance and pull equity without paying break costs. You're already moving loans, so bundling the equity release into that process saves you time and often money, since you're only paying one set of refinance costs instead of two separate transactions.

The valuation on your existing property is one of the key steps. If the valuer comes in lower than you expected, your usable equity drops and the whole plan can fall apart. This is more common in regional markets where comparable sales data is thinner and valuers take a conservative view. If you're borderline on serviceability or loan-to-value ratio, even a $20,000 difference in valuation can be the difference between approval and rejection.

When Refinancing for Equity Makes Sense and When It Doesn't

Refinancing to access equity works when you've got a decent amount of usable equity, strong serviceability, and a clear investment strategy.

It doesn't work when you're stretching to access every last dollar of equity, leaving yourself with no buffer if the investment property sits vacant for a few weeks or if rates rise further. It also doesn't work if your current home loan has significant break costs because you're still mid-way through a fixed term, unless the numbers on the investment property are strong enough to absorb those costs and still deliver a return.

In Northern NSW, where property values in some areas have grown solidly over the past few years, refinancing to access equity has become a common strategy for locals looking to buy an investment property in nearby towns or coastal areas. But it only makes sense if the equity is genuinely there, the serviceability stacks up, and the costs are built into the plan from the start.
