Top tips to choose investment loan features

What investment loan features matter for FIFO mobile plant operators

You need features that reduce holding costs during vacancies, give you access to equity without refinancing, and preserve your tax position. Interest-only repayments, offset accounts, and redraw facilities are the three that do the most work for FIFO investors on roster. Split rate structures and portability clauses sit behind those, but they only matter if your borrowing strategy or property plan changes mid-loan.

Consider a mobile plant operator working 14/7 rosters in the Pilbara who bought a four-bedroom house in Townsville at $710,000 with a 20 per cent deposit. He set the loan to interest-only for the first five years and attached an offset account. His rental income covers most of the interest, but he keeps his roster bonuses in the offset rather than paying down the loan. That choice reduces his taxable interest expense by around $3,000 a year while keeping those funds accessible for the next deposit. When he moves to a principal and interest structure in year six, he can redirect the same income to reduce the loan balance or leave it offset if another property comes up. The feature doing the work is the offset, not the repayment type. The repayment type just controls the size of the monthly obligation.

If your goal is to hold the property long enough to pay down debt using rental income and salary, an interest-only period doesn't help. If your goal is to keep monthly costs low, build accessible cash reserves, and use equity to buy again, it does. The feature matches the strategy, not the property type.

Interest-only repayments and when they reduce investor risk

Interest-only repayments let you pay the loan interest each month without reducing the principal. The monthly payment is lower than a principal and interest loan, and all the interest remains deductible. You can switch to principal and interest at any point during the interest-only term, but you cannot extend the term beyond what the lender approved at settlement unless you refinance.

FIFO investors working in cyclical industries use interest-only periods to match cash flow to roster patterns. A mobile plant operator on a 20/8 roster earning $160,000 a year might have six weeks of the year with reduced income if rosters are cut or a shutdown period runs long. Interest-only repayments on an investment property loan give him room to cover holding costs from salary during those weeks without dipping into savings. The loan does not reduce in size, but the property continues to generate rental income and depreciation deductions, and the interest cost stays fully deductible under current negative gearing rules for properties held before 12 May 2026 or classified as eligible new builds.

From the 2027-28 income year, losses on established investment properties acquired after 12 May 2026 can only be offset against other residential property income, not salary. Interest-only loans on those properties still work, but the tax benefit is deferred until you sell or acquire more properties. If you are borrowing now for a property that settles after that date and is not a new build, model your cash flow assuming the interest is not reducing your taxable salary. That changes the affordability equation for some FIFO workers, particularly those relying on negative gearing to cover part of the holding cost. You can find more detail on how those changes flow through to FIFO investors at FIFO Investment Loans.

Offset accounts versus redraw facilities

An offset account is a transaction account linked to your loan. The balance in the account reduces the interest charged on the loan, but the funds stay accessible. A redraw facility lets you withdraw extra repayments you have made above the minimum, but those funds sit inside the loan structure rather than in a separate account.

For FIFO workers, the offset account preserves the deductibility of interest on the full loan amount. If you put $40,000 into an offset account linked to a $560,000 investment loan, you only pay interest on $520,000, but the loan balance stays at $560,000. If you later withdraw that $40,000 to fund a second deposit, the interest on the full $560,000 remains deductible because the loan purpose has not changed. If you had instead made $40,000 in extra repayments and then redrew those funds for a new purchase, the Australian Taxation Office may treat the redrawn portion as a separate loan with a different purpose, and only the interest on the portion used to hold the original investment property stays deductible. The difference is not theoretical. It determines whether you can claim the interest or not.

In our experience, FIFO mobile plant operators holding investment property in Mackay or Townsville prefer offset accounts because roster income is irregular and they want the option to move funds between properties without triggering a tax problem. Redraw works if you are certain the funds will only ever be used to reduce the loan on that specific property. If there is any chance you will use those funds elsewhere, an offset is the safer structure. Not all lenders offer offset accounts on investment loans, and those that do may charge a higher interest rate or annual fee. The cost difference is usually between 0.10 per cent and 0.25 per cent per year. On a $500,000 loan, that is $500 to $1,250 annually. You recover that cost quickly if the offset saves you a single tax dispute or lets you access $20,000 for another deposit without refinancing.

Fixed rate versus variable rate for investment property loans

A variable rate moves with the lender's pricing, which generally tracks the Reserve Bank's cash rate and funding costs. A fixed rate locks your interest cost for a set term, usually between one and five years. At the end of the fixed term, the loan reverts to the lender's standard variable rate unless you refinance or negotiate a new fixed period.

FIFO investors on variable rates benefit from offset accounts and the ability to make extra repayments without penalty. FIFO investors on fixed rates give up those features in exchange for repayment certainty. If you fix the rate and then want to break the loan early to refinance, sell, or pay down a lump sum, the lender will charge break costs. Those costs can run into tens of thousands of dollars if rates have fallen since you fixed. They are calculated based on the difference between your fixed rate and the lender's current wholesale funding cost, multiplied by the remaining term. The formula is not transparent, and the amount is not capped. If rates rise after you fix, there is no break cost, but you also cannot take advantage of offset or redraw features on most fixed rate products.

A split rate structure lets you fix part of the loan and keep part variable. That approach works for FIFO investors who want repayment certainty on the base loan but need flexibility to use offset or make lump sum payments from roster bonuses. The variable portion carries the offset account, and the fixed portion locks in part of your cost. The downside is that you pay two sets of fees and you increase the complexity of your tax reporting, because the interest on each split may differ and you need to track both.

Loan portability and why it matters when you sell and buy again

Portability lets you transfer your existing loan from one security property to another without discharging and rewriting the loan. Not all lenders offer it, and those that do apply conditions. The new property must meet the lender's current lending policy, and you cannot increase the loan amount beyond what equity and serviceability allow. If the new property is more expensive and you need to borrow more, you will need to apply for a top-up, which is assessed as new lending.

FIFO mobile plant operators who plan to sell an investment property in Townsville and buy another in the same city or a different regional market use portability to avoid discharge fees, new application fees, and valuation costs. Those fees add up to between $1,500 and $3,000 per transaction. Portability also preserves your existing interest rate if that rate is lower than current market rates. If you locked in a variable rate of 5.8 per cent two years ago and current rates are 6.4 per cent, keeping the existing loan saves you 0.6 per cent per year on the transferred balance.

The limitation is that portability does not let you access equity in the old property to fund the new deposit. If you are selling a property worth $750,000 with a $450,000 loan and buying a property worth $850,000, you will have $300,000 in equity from the sale but you still need to apply for additional borrowing to reach the new purchase price. Some lenders will let you port the $450,000 and top up to $680,000 in a single approval process. Others require you to discharge the old loan and write a new one. Check the lender's portability policy before you list the property for sale. If you are planning to grow your portfolio rather than trade properties, equity release structures are usually more useful than portability. You can explore those options further at Equity Release Loans for FIFO Workers.

Choosing loan features that match your timeline and portfolio plan

Your loan features should reflect how long you plan to hold the property, whether you intend to buy more, and whether you are relying on salary or rental income to cover holding costs. A FIFO mobile plant operator buying his first investment property in Andrews Farm with a five-year hold period and a plan to sell and upgrade needs different features than a FIFO worker building a three-property portfolio over ten years. The first scenario suits a principal and interest loan with low fees and no offset, because the goal is to reduce debt and sell. The second scenario suits interest-only with offset and portability, because the goal is to preserve cash flow, access equity, and acquire again.

If your roster income includes overtime or allowances that are shaded to 80 per cent for serviceability, your borrowing capacity is lower than a worker on the same gross income earning a flat salary. That shading affects how much you can borrow, but it does not change the loan features you should use once the loan is approved. You still benefit from offset accounts and interest-only structures if your goal is portfolio growth. The shading just means you might need a larger deposit or a longer savings period to reach the same loan amount. You can learn more about how FIFO income is assessed at FIFO Property Loans.

The 2026 changes to negative gearing and capital gains tax do not affect loans written before those dates, but they do affect the economics of new purchases. If you are buying an established property that settles after 12 May 2026, the interest on that loan will only be deductible against other residential property income from the 2027-28 income year. If you are buying an eligible new build, you keep full negative gearing and you also get a choice between the old 50 per cent capital gains discount and the new indexed cost base with a 30 per cent minimum rate when you sell. Those tax settings influence whether a property makes sense as an investment, but they do not change the fact that an offset account is still more flexible than redraw, or that interest-only still reduces your monthly commitment compared to principal and interest.
