What are Variable Rate Investment Loans for FIFO Workers?

A variable rate investment loan charges interest that moves with the market, which means your repayments shift when the lender adjusts their rates.

Most FIFO mobile plant operators stick with variable rate loans for investment properties because the flexibility suits roster income and long-term hold strategies. You can make extra repayments when you've banked a few weeks on site without penalty, and you're not locked in if you need to refinance or sell before a fixed term ends. The rate itself moves, but the control stays with you.

How Variable Rate Investment Loans Are Priced

Variable rates for investors sit higher than owner-occupier rates, usually by 0.30 to 0.60 percentage points. Lenders price investor loans higher because the risk profile is different. If someone runs into trouble, they'll prioritise the roof over their head before a rental property. That pricing gap widens further if you're borrowing above 80 per cent loan to value ratio or choosing interest-only repayments.

The actual rate you're offered depends on your deposit size, loan amount, and whether you're making principal and interest or interest-only payments. A mobile plant operator refinancing an existing investment property with 40 per cent equity and steady FIFO income will see sharper pricing than someone stretching to 90 per cent LVR on their first purchase.

Interest-Only Repayments on Variable Rate Loans

Interest-only periods on investment loans run for up to five years, sometimes longer if your equity position is strong. You pay only the interest charged each month, which keeps the repayment lower and frees up cash for other uses. The loan balance doesn't reduce, but if the property's value is climbing and you're claiming the interest as a deduction, that structure can work well for building wealth over time.

Consider a mobile plant operator who bought a unit near a regional hospital at 75 per cent LVR. They chose interest-only on a variable rate, which gave them flexibility to funnel extra income into offset when they were on swing, then redirect that cash into a second deposit two years later. The interest-only term kept their serviceability under the debt-to-income cap while they were carrying one property and preparing to buy another. Once the interest-only period ended, they switched the loan to principal and interest and kept the variable rate.

When the Rate Moves, What Actually Changes

When your lender adjusts the variable rate, your repayment amount changes from the next billing cycle. If you're on principal and interest, both the interest portion and the principal portion of each payment shift. If you're on interest-only, the entire repayment moves with the rate because you're only covering the interest charge.

Lenders don't always move in lockstep with the Reserve Bank. Some pass on cash rate cuts in full, others hold back part of the reduction. Some lift rates before the RBA moves, citing funding costs. That inconsistency is one reason refinancing an investment loan every few years makes sense. If your current lender has drifted 0.40 percentage points above the market and you're carrying a loan amount above $400,000, the annual difference is measurable.

Variable Rate Features That Suit FIFO Investors

Most variable rate investment loans include an offset account, a redraw facility, or both. An offset account holds your cash in a separate transaction account and reduces the interest charged on the loan balance by the offset balance each day. If you've got $30,000 sitting in offset and a loan balance of $450,000, you only pay interest on $420,000. That structure suits FIFO income because you can park your pay during roster periods and let it work against the loan without locking it away.

Redraw lets you pull back any extra repayments you've made above the scheduled amount. Not all lenders offer redraw on interest-only investment loans, and some cap how much you can pull back or charge a fee per withdrawal. If you're planning to use extra repayments as a cash buffer, check the redraw terms before you settle. An offset account is cleaner for most FIFO setups because the cash stays accessible and doesn't trigger redraw restrictions.

Refinancing a Variable Rate Investment Loan

Refinancing a variable rate loan doesn't carry break costs, which is one of its biggest advantages over fixed terms. If you find a lender offering a lower rate, better offset terms, or access to further equity for your next purchase, you can move without penalty. The only costs are the usual discharge fee from your current lender and any application or valuation fees from the new one.

FIFO workers building a portfolio often refinance every two to three years to keep their rate sharp and unlock equity as properties grow in value. If you bought a property three years ago at 80 per cent LVR and it's now sitting at 65 per cent, that equity can fund your next deposit without selling. A debt recycling strategy can also be layered in at refinance if you're paying down non-deductible debt and want to convert it into deductible investment debt over time.

What Rate Discount You Can Expect

Published variable rates are rarely the rate you'll actually pay. Lenders offer discounts off the standard variable rate based on your loan size, LVR, and relationship. A loan amount above $500,000 with an LVR below 70 per cent will typically pull a deeper discount than a $300,000 loan at 85 per cent. The gap can be 0.20 to 0.50 percentage points, which adds up over the life of the loan.

Negotiating the discount upfront matters, but so does making sure the discount doesn't expire after a honeymoon period. Some lenders advertise a sharp rate for the first year, then revert to a higher margin once the intro period ends. Read the rate structure in the loan offer and confirm whether the discount holds for the life of the loan or needs renegotiating down the track.

How the 1 July 2027 Tax Changes Affect Variable Rate Strategy

From 1 July 2027, rental losses on established residential properties purchased after 7:30pm AEST on 12 May 2026 can only be offset against rental income or carried forward. They can't be offset against your FIFO wages. Properties held before that time, and eligible new builds purchased after, are not affected. That change shifts the calculation for negative gearing and may push some investors toward new builds or toward holding fewer properties with stronger rental yields.

If you're buying an established property under the new rules, a variable rate still offers flexibility to adjust your repayment strategy as rental income changes or as you add more properties to your portfolio. The ability to make extra repayments and access offset or redraw becomes more useful when you're managing cash flow across multiple rentals without the tax offset you used to rely on.
