A fixed rate loan locks your interest rate for a set period, typically between one and five years. The primary features include rate certainty, limited flexibility during the fixed period, and break costs if you repay early or switch before the term ends.
How Rate Lock Periods Work
The rate lock period determines how long your interest rate remains unchanged. Most lenders offer one, two, three, four or five year terms. Your repayments stay identical throughout that period regardless of market movements. At the end of the fixed term, your loan reverts to the lender's variable rate unless you refinance or lock in another fixed period.
Consider a buyer who secures a three year fixed rate through the Australian Government 5% Deposit Scheme in Lyneham. The repayment amount remains constant for those three years. If variable rates drop during that period, they continue paying the fixed rate. If rates rise, they are protected from the increase. Once the three years expire, the loan moves to the prevailing variable rate and repayments adjust accordingly.
Extra Repayments and Offset Accounts on Fixed Loans
Most fixed rate loans allow limited extra repayments, typically capped at $10,000 to $30,000 per year depending on the lender. Some lenders permit no additional repayments at all during the fixed term. Exceeding the cap triggers break costs. Offset accounts are rarely available with fixed rates. Where they exist, the offset usually applies to a linked variable portion rather than the fixed component.
If building deposit savings while renting in the Dickson precinct and planning to use those funds for future repayments, a split loan structure provides more flexibility. A portion remains variable with full offset access, while the remainder locks in a fixed rate for stability.
Break Costs and When They Apply
Break costs arise when you discharge, refinance or significantly overpay a fixed rate loan before the term ends. The lender calculates the cost based on the difference between your fixed rate and the wholesale rate the lender can now earn by re-investing the funds for the remaining term. If market rates have fallen since you fixed, break costs can be substantial. If rates have risen, break costs may be minimal or nil.

In our experience, buyers underestimate how often circumstances change. A job relocation, property upgrade or relationship change can all require selling or refinancing before a fixed term expires. Lenders provide a break cost estimate before you proceed, but the final figure is calculated at discharge. For buyers using the Australian Government 5% Deposit Scheme in Canberra, where property price caps allow purchases up to $750,000, break costs on a five year fixed term can run into tens of thousands of dollars if rates drop significantly during the term.
Fixed to Variable Switching
Some lenders permit switching from fixed to variable before the term ends without break costs, usually subject to conditions. Others charge a fixed administration fee rather than a full break cost calculation. A minority of lenders offer genuine rate switching flexibility, particularly on products designed for first home buyers. Most fixed loans do not include this feature and require either waiting for the term to expire or paying break costs to exit.
If planning to use the ACT Home Buyer Concession Scheme, which from 1 July 2026 provides full conveyance duty exemption regardless of property value or income, it is worth confirming switching terms before committing to a fixed rate. The scheme requires occupying the property as your principal residence for at least one year. If circumstances change shortly after settlement, a fixed loan with no switching flexibility limits your options.
Portability and Loan Transfers
Portability allows transferring a fixed rate loan to a new property without triggering break costs. Few lenders offer genuine portability. Where it exists, conditions typically include settling the new purchase within a short timeframe, borrowing the same or a lower amount, and maintaining the same loan structure. If upsizing or requiring additional borrowing, the new funds are usually provided at current rates while the existing fixed balance transfers across.
For buyers considering future property moves within Canberra suburbs, portability is rarely worth prioritising over rate competitiveness and offset access. The likelihood of meeting all portability conditions when actually selling and buying is low.
Redraw Facilities on Fixed Loans
Redraw allows accessing extra repayments made during the loan term. On fixed rate loans, redraw is either unavailable or restricted. Where permitted, it may be subject to minimum amounts, processing delays and fees. Some lenders count redrawn funds toward your annual extra repayment cap, meaning redrawing and re-contributing can trigger break costs if the cap is exceeded.
Buyers planning to make irregular extra repayments should confirm redraw terms in writing before settlement. A variable rate loan or split structure with a variable portion provides more reliable access to surplus funds.
Split Loan Structures
A split loan divides your borrowing between fixed and variable components. Common splits include 50/50, 70/30 or 80/20. The variable portion provides offset account access and repayment flexibility, while the fixed portion delivers rate certainty. The split can be adjusted at the end of the fixed term.
This structure suits buyers in Lyneham who anticipate receiving irregular income, such as annual bonuses or family contributions, that they want to deposit into an offset account while still maintaining partial rate protection. The variable portion typically incurs a slightly higher rate than a standalone variable loan due to the split structure, but the difference is usually minor.
Rate Comparison and Product Selection
Fixed rates vary significantly between lenders and loan types. Lenders offering participation in the 5% Deposit Scheme may reserve their most competitive fixed rates for that product. Others provide better fixed rates on standard loans with a 20% deposit. Comparing fixed rates requires confirming whether offset accounts, extra repayments, redraw and portability are included, not just reviewing the interest rate figure.
Buyers accessing the ACT Home Buyer Concession Scheme and borrowing through a participating lender should request fixed rate quotes from both scheme and non-scheme loan products. The scheme does not restrict loan features, but some lenders structure their products differently depending on the loan type. Working with a mortgage broker in Lyneham provides access to multiple lender panels and feature comparisons across product types.
Fixed Rate Expiry and Reversion Planning
When a fixed term expires, the loan reverts to the lender's variable rate. Reversion rates are often higher than the discounted variable rates offered to new customers. Most lenders send a reminder 30 to 90 days before expiry. Buyers can lock in a new fixed term, switch to the standard variable rate, negotiate a discounted variable rate, or refinance to a different lender.
Reviewing options at least 60 days before expiry allows time to compare rates, lodge applications and settle before reversion occurs. For buyers who initially used the 5% Deposit Scheme, equity growth during the fixed term may provide access to lower rates or better loan features at expiry. A fixed rate expiry review identifies whether staying with the current lender or refinancing delivers better value.

Frequently Asked Questions
Can I make extra repayments on a fixed rate home loan?
Most fixed rate loans allow limited extra repayments, typically capped at $10,000 to $30,000 per year depending on the lender. Exceeding the cap or making extra repayments where none are permitted triggers break costs. Some lenders do not allow any additional repayments during the fixed term.
What happens when my fixed rate term expires?
When the fixed term ends, your loan reverts to the lender's standard variable rate unless you lock in a new fixed term, negotiate a discounted variable rate, or refinance to another lender. Lenders typically send a reminder 30 to 90 days before expiry, and it is worth reviewing options at least 60 days beforehand to allow time for applications and settlement.
Do fixed rate loans have offset accounts?
Offset accounts are rarely available with fixed rate loans. Where they exist, the offset usually applies to a linked variable portion rather than the fixed component. A split loan structure with a variable portion provides full offset access while maintaining partial rate certainty on the fixed portion.
How are break costs calculated on a fixed rate loan?
Break costs are calculated based on the difference between your fixed rate and the wholesale rate the lender can now earn by re-investing the funds for the remaining term. If market rates have fallen since you fixed, break costs can be substantial. If rates have risen, break costs may be minimal or nil.
Can I transfer a fixed rate loan to a new property?
Few lenders offer genuine portability on fixed rate loans. Where it exists, conditions typically include settling the new purchase within a short timeframe, borrowing the same or a lower amount, and maintaining the same loan structure. If upsizing or requiring additional borrowing, new funds are usually provided at current rates while the existing fixed balance transfers across.
