What Not to Do When Refinancing Investment Properties

Most mechanics know the cost of running the wrong spec. Same applies when refinancing an investment property.

The difference between a decent refinance and one that costs you money usually comes down to three things: timing the switch before your fixed rate ends, keeping deductions intact, and not letting equity sit idle when you could be using it to buy the next place. Get those wrong and you'll pay for it, either in break costs, lost tax benefits, or missed opportunities.

Why Investment Property Refinancing Hits Different

Refinancing an investment loan isn't the same as switching your home loan. The entire structure is built around tax deductions, so any move you make has to protect that setup. Interest on an investment loan is tax-deductible, which means every dollar you pay in interest reduces your taxable income. Change the loan purpose or withdraw equity for personal use and the ATO will reclassify part of that debt as non-deductible. We regularly see this happen when someone pulls equity out for a car or holiday without separating the funds properly.

Consider a mechanic with a rental property in Port Hedland who refinances to access equity for a new ute. If that equity gets added to the existing investment loan without a split, the portion used for the ute stops being deductible. On a loan amount that increases from say, the original loan balance to a higher figure, that could mean losing deductions on tens of thousands of dollars. The outcome depends entirely on how the loan is structured at settlement. Keep investment debt separate from personal debt, always.

Fixed Rate Expiry and When to Move

If your fixed rate period is ending in the next three months, that's when you start the refinance process. Wait until after it expires and you'll likely cop a few months on the lender's standard variable rate, which is almost always higher than what you could lock in elsewhere. Start too early and you'll wear break costs that wipe out any saving from a lower rate.

Break costs apply when you exit a fixed rate early. They're calculated based on the difference between your fixed rate and the wholesale rate your lender can now get for the remaining term. If rates have dropped since you fixed, the break cost will sting. If rates have gone up, the break cost might be zero or even result in a rebate, though that's rare. The calculation isn't something you can do yourself, you need to request it from your current lender.

In our experience, mechanics coming off fixed rates often assume they need to stick with their current lender to avoid hassle. That assumption costs money. A fixed rate expiry is the ideal time to shop around because there's no penalty for leaving once the term ends. Submit your refinance application about six to eight weeks before the expiry date. That gives enough time to compare offers, get a property valuation done if required, and settle with the new lender right as the fixed term wraps up.

Accessing Equity Without Killing Deductions

Releasing equity to fund a deposit on another investment property is one of the few moves that keeps the debt fully deductible. The ATO allows this because the borrowed funds are being used to generate assessable income. Withdraw the same equity to pay off your home loan or fund personal expenses and the story changes.

Let's say you've got a rental property with equity you want to access for a second investment. You refinance and increase the loan amount to release that equity. As long as those funds go directly toward the deposit, stamp duty, and purchase costs for the next investment, the interest on the entire loan stays deductible. The key is keeping the paper trail clean. Funds should move from the loan account to the solicitor's trust account or vendor, not into your personal account for a few weeks before being used. The ATO will trace the use of funds, not just the intent.

This is where a debt recycling strategy can come into play as well, though that's a separate setup. For straightforward equity release to fund another investment, the focus is on proving the borrowed funds went toward an income-producing asset.

What Happens If You Refinance for the Wrong Rate Type

Switching from variable to fixed or fixed to variable needs to match your actual plans for the property. Lock in a fixed rate when you're planning to sell in 12 months and you'll pay break costs when you discharge the loan early. Stick on a variable rate when you'd sleep easier with certainty and you'll spend the next few years second-guessing every rate rise.

For a FIFO worker with inconsistent income patterns depending on roster and shutdowns, a variable rate with offset or redraw gives you flexibility to park lump sums and reduce interest without being locked in. Fixed rates suit properties you're holding long-term where you want to lock in repayments and ignore rate movements. There's no universal right answer, it depends on what you're doing with the property and how you manage cash between swings.

One thing to watch: some lenders restrict offset accounts on investment loans or charge extra for them. If you're used to having one and rely on it to manage tax, make sure the new loan includes it before you commit. Redraw facilities are common but they don't reduce interest daily like an offset does, and some lenders restrict access once you've made extra repayments.

How the Refinance Process Actually Works for Investment Loans

You'll need to provide rental income evidence, usually a lease agreement and bank statements showing the rent hitting your account. Lenders assess investment loans differently to owner-occupied loans. They'll typically only count 80% of the rental income when calculating your borrowing capacity, and some apply higher interest rate buffers to stress-test your ability to service the debt if rates go up.

A property valuation will likely be required unless you're refinancing a small percentage of the property's value. The lender will organise this, and it'll either be a desktop valuation, a kerbside assessment, or a full inspection depending on the loan amount and location. If the valuation comes in lower than expected, your available equity shrinks and you might not be able to borrow as much as planned.

Your current lender will also charge a discharge fee, usually between a few hundred dollars, when you leave. Factor that into the cost of switching. Some lenders offer cashback incentives to cover these costs, but read the terms because they often require you to stay with the new lender for a minimum period or the cashback gets clawed back.

Loan Features That Matter for Rental Properties

Offset accounts, redraw, and the ability to make extra repayments all sound similar but they're not. An offset account is a separate transaction account linked to your loan. Every dollar in it reduces the interest you're charged, and you can access the money anytime. This is useful if you're managing fluctuating income on a FIFO roster and want to reduce interest during cashed-up periods without losing access to funds.

Redraw lets you pull back extra repayments you've made on the loan, but some lenders restrict how often you can do it or charge fees. And if the ATO decides those extra repayments changed the character of the loan, you could run into deductibility issues. Offset accounts are cleaner for investment loans because the funds never technically go into the loan, they just reduce the interest calculated.

Interest-only periods are another feature worth considering. Paying interest-only on an investment loan maximises your tax deductions and frees up cash flow, which you can then direct toward paying down non-deductible debt like your home loan. Not every lender offers interest-only on a refinance, and those that do will usually cap it at five years before reverting to principal and interest. If that's part of your strategy, confirm it's available before you apply.

Why a Loan Review Beats Guessing

A loan health check involves pulling your current loan details, comparing them against what's available now, and working out whether a switch makes sense. It's not just about the interest rate. You need to factor in discharge fees, application fees, valuation costs, and any ongoing fee differences between your current loan and the new one. Sometimes the numbers say stay put, sometimes they say move.

For FIFO workers, borrowing capacity can shift depending on how lenders treat your income. Some count your full base salary, others only accept what's on your PAYG summary, and a few will include allowances if they're consistent. If your income structure has changed since you took out the original loan, a refinance might unlock more equity than you think. Or it might restrict it. You won't know until someone runs the numbers with current lender policies.
