Fixed, Variable, and Split Loans: What ADF Members Need

Fixed Rate Loans Lock Your Repayment for a Set Term

A fixed rate locks your interest rate for a period you choose, usually one to five years. Your repayment stays the same regardless of what the Reserve Bank does. You know exactly what leaves your account each fortnight, and if rates climb, you're protected.

Consider a buyer purchasing near Kapooka who expects a posting within three years. A three-year fixed rate gives certainty during that period. If the property becomes an investment after the posting, the borrower knows the holding cost won't shift unexpectedly. The limit is that most fixed loans restrict additional repayments to around $10,000 to $30,000 per year depending on the lender, and offset accounts are rarely available. If you deploy and bank extra pay, you can't park it in an offset to reduce interest daily. You can make some extra repayments within the annual cap, but anything beyond that may trigger break costs if you want to exit the fixed term early.

If you're posted and need to sell before the fixed period ends, break costs can apply. These are calculated based on the difference between your locked rate and the lender's current cost of funding for the remaining term. The amount varies widely depending on how far rates have moved and how much time is left. Some lenders waive break costs if you port the loan to a new property, but that only works if you're buying again in the same market cycle.

Variable Rate Loans Give You Full Access to Offset and Redraw

Variable rates move with the market, but they come with flexibility that fixed loans don't offer. You can make unlimited extra repayments, redraw funds if the loan allows it, and link an offset account that reduces the interest you're charged every day.

An offset account sits alongside your loan. Every dollar in the account reduces the balance on which interest is calculated. If you have a $500,000 loan and $30,000 in your offset, you're only charged interest on $470,000. For ADF members who deploy and accumulate pay without spending it, an offset can cut years off the loan term without locking the funds away. The money stays accessible, which matters if you're posted at short notice or need to cover relocation costs before the next posting allowance arrives.

Redraw works differently. Extra repayments go into the loan and reduce the principal, but you can usually pull that money back out if needed. Some lenders limit redraw access or charge fees. Others allow instant redraw through online banking. The difference between redraw and offset is control. Offset funds are always yours. Redraw funds have been paid into the loan, and while most lenders make them available, access isn't guaranteed in every situation, especially if the loan is restructured or switched to interest-only.

Variable rates also mean your repayment can increase if the lender raises rates. That requires a buffer in your budget. Most lenders assess your ability to service the loan at a rate higher than what you'll actually pay, usually between 3% and 4% above the offered rate, so approval implies you can handle rises. But knowing you can service a rate increase and preferring not to are different things.

Split Loans Let You Use Both Structures at Once

A split loan divides your borrowing between fixed and variable portions. You might fix 50% for three years and leave 50% variable with an offset account. You get rate protection on half the debt and full flexibility on the other half.

This structure is common among ADF members who want some certainty but also expect to use an offset account actively. If you fix $250,000 and keep $250,000 variable, you can still deposit deployment savings into the offset and reduce interest on the variable portion. The fixed half keeps your minimum repayment stable, even if variable rates rise sharply.

The split can be any proportion. Some borrowers fix 70% and keep 30% variable. Others do the reverse. The decision depends on how much you expect to save and how much rate movement you're willing to carry. A 70/30 split in favour of fixed rates makes sense if your budget is tight and you need maximum repayment certainty. A 30/70 split works better if you'll be deploying regularly and want the majority of your loan to benefit from offset contributions.

You can also stagger fixed rate expiry dates by splitting into multiple fixed portions with different terms. For example, fix one portion for two years, another for four years, and leave the rest variable. This spreads your exposure to rate changes over time rather than having the entire fixed portion revert to variable on the same day. Managing your fixed rate expiry becomes less of a single event and more of a rolling decision.

How Lenders Assess ADF Income for Different Loan Types

All three structures require the same income assessment. Lenders treat your base salary as stable income and usually accept allowances that are regular and ongoing, such as service allowance or posted allowance. Deployment allowances are handled differently depending on the lender. Some will include them if you've been deploying regularly and the pattern is likely to continue. Others exclude them entirely.

This affects how much you can borrow, but it doesn't change which loan type you can access. Fixed, variable, and split loans are all available to ADF members using standard lending policies. If a lender offers no LMI loans for ADF members, that benefit applies regardless of whether you choose fixed, variable, or split. The same is true for low deposit loans and other ADF-specific products.

The distinction comes after settlement. If you're on a fixed loan and your income increases due to a promotion or deployment, you can't increase your repayment beyond the annual cap without triggering restrictions. On a variable loan, you can increase repayments immediately and reduce your interest accordingly.

Which Structure Works for Members Stationed in Kapooka

Kapooka is a training base, and most personnel stationed there are either in training or posted as instructors. Instructors are typically on postings of two to four years. Recruits and trainees won't be buying while they're completing initial training, but instructors often do, especially if they've been in long enough to build savings or have a partner with stable local employment.

The Wagga Wagga area around Kapooka offers property options well within reach for ADF buyers using 5% deposit schemes, and stamp duty concessions in New South Wales reduce upfront costs further. The question is what happens to the property after posting. If you plan to hold it as an investment, a split loan gives you the option to keep an offset linked to the variable portion and use that to manage rental income and expenses. If you plan to sell when posted, a variable loan avoids break cost risk entirely.

Fixed loans make sense if you're confident you'll hold the property through the fixed term, either as an owner-occupier or an investment, and you want protection against rate rises during that period. Variable loans suit buyers who value access to offset and redraw more than rate certainty. Split loans are the middle ground and the most common choice among ADF members who want both.
