A fixed rate home loan locks your interest rate for a set period, protecting you from rate rises but restricting flexibility if your circumstances change.
For self-employed business owners, that certainty matters in a different way than it does for salaried buyers. Your income varies by season, contract, or trading conditions. Knowing your mortgage repayment in advance helps you forecast cash flow, allocate retained earnings, and separate business decisions from housing costs. The downside is that fixed loans typically limit extra repayments, restrict offset account access, and charge break costs if you need to refinance or sell before the fixed term ends.
Fixed Rate Certainty for Variable Income
A fixed interest rate protects your repayments from rate increases during the fixed period, usually between one and five years. If rates rise during that time, your repayment stays the same. If rates fall, you continue paying the higher fixed rate until the term ends.
Consider a business owner in Marrickville who secured a three-year fixed rate at the start of a rate hiking cycle. Over eighteen months, variable rates increased seven times. Their repayment held steady while variable borrowers saw monthly costs increase by hundreds of dollars. That stability let them commit to a commercial lease and hire staff without recalculating household budgets every quarter. When the fixed term ended, they switched to a split rate structure to retain some certainty while regaining offset access.
Limited Extra Repayments and Offset Restrictions
Most fixed rate home loans cap extra repayments at around $10,000 to $30,000 per year. If your business has a strong year and you want to pay down debt faster, you cannot do so without triggering break costs. Offset accounts are either unavailable or offer only partial offset functionality on fixed loans, which means surplus cash in your transaction account earns minimal interest instead of reducing your loan balance.
For self-employed buyers who experience uneven income, this creates a planning challenge. In months where revenue exceeds expenses, you may want to park funds in an offset to reduce interest and keep the cash accessible. On a fixed loan, that option disappears. You either leave the cash in a low-interest savings account or prepay the loan within the annual cap and lose access to those funds.
Break Costs and Early Exit Penalties
Break costs apply when you exit a fixed rate loan before the term ends. This happens if you refinance, sell the property, or repay the loan in full. The lender calculates the cost based on the difference between your fixed rate and the current wholesale rate for the remaining term. If rates have fallen since you fixed, the cost can be substantial.
A self-employed buyer in Newtown fixed a loan for five years, then sold their property after three years to upsize. Rates had dropped during that period, and the break cost came to $14,800. That figure was not disclosed upfront because it depends entirely on rate movements. They absorbed the cost as part of the sale proceeds, but it reduced their deposit for the next purchase and meant they paid Lenders Mortgage Insurance on the new loan when they otherwise would have avoided it.
When Fixed Rates Suit Self-Employed Borrowers
Fixed rates work when you prioritise certainty over flexibility and do not expect to refinance, sell, or make large lump sum repayments during the fixed term. They suit buyers who have minimal surplus cash flow and benefit more from predictable repayments than from offset functionality.
Self-employed borrowers often face higher scrutiny during home loan applications due to variable income and tax minimisation strategies. If you have recently secured a loan that reflects your full borrowing capacity, locking in the rate protects that structure while you build equity and stabilise your financial position. You avoid the risk of rate rises eroding your repayment buffer during the first few years of ownership, which is when cash flow is usually tightest.
Fixed loans also suit buyers in suburbs like the Inner West or Lower North Shore, where property values are high and any rate increase has a pronounced impact on monthly repayments due to the larger loan amount. Paying an extra 1% on a $900,000 loan costs significantly more than on a $500,000 loan, so the insurance value of fixing becomes more relevant.
Comparing Fixed and Variable Rates Before Committing
Fixed rates are typically priced based on the lender's expectation of where variable rates will move over the fixed term. If the market expects rates to fall, fixed rates may be higher than current variable rates. If the market expects rates to rise, fixed rates may be lower. Your decision should reflect your risk tolerance and cash flow needs, not just the rate differential at application.
Before committing to a fixed rate, review your business cycle and upcoming financial commitments. If you expect a large tax refund, contract payment, or asset sale within the fixed term, a variable or split loan structure may serve you more effectively. If your income is steady and you prefer to remove interest rate risk from your planning, a fixed rate delivers that outcome.
When comparing home loan rates, look beyond the advertised rate and assess the loan features. Some fixed loans allow partial offset or higher prepayment caps. Others include portability, which lets you transfer the loan to a new property without break costs. These features cost more in rate terms but may justify the difference depending on your circumstances.
Transitioning From Fixed to Variable at Expiry
When your fixed rate expires, the loan automatically reverts to the lender's standard variable rate unless you take action. That revert rate is typically higher than the variable rate available to new customers, so you lose any rate advantage unless you refinance or renegotiate.
Self-employed borrowers should begin the refinance process at least three months before the fixed term ends. Your financial position may have changed since the original application, and lenders will reassess your income using updated tax returns and business financials. If your income has declined or your business structure has changed, you may not qualify for the same loan amount or rate, which limits your options at expiry.
If your circumstances have remained stable or improved, refinancing at expiry gives you access to current home loan rates and lets you restructure the loan to include offset accounts, redraw facilities, or a split rate arrangement. You also regain the ability to make unlimited extra repayments, which becomes valuable as your loan matures and you look to accelerate repayment.

Frequently Asked Questions
What happens if I need to sell my property during a fixed rate term?
You will likely incur break costs, which are calculated based on the difference between your fixed rate and the lender's current wholesale rate for the remaining term. If rates have fallen since you fixed, the cost can be significant and will reduce your sale proceeds.
Can I make extra repayments on a fixed rate home loan?
Most fixed rate loans allow limited extra repayments, typically between $10,000 and $30,000 per year. Exceeding this cap will trigger break costs, so if you expect variable income with large lump sums, a variable or split loan may be more suitable.
Do fixed rate loans offer offset accounts?
Most fixed rate loans do not offer full offset functionality. Some lenders provide partial offset or no offset at all, which means surplus cash cannot reduce your interest in the same way it would on a variable loan.
How do I avoid paying a high revert rate when my fixed term ends?
Start the refinancing process at least three months before your fixed term expires. This gives you time to reassess your loan structure, access current rates, and avoid automatically rolling onto the lender's standard variable rate, which is usually higher than rates available to new customers.
Are fixed rates suitable for self-employed borrowers?
Fixed rates suit self-employed borrowers who value repayment certainty over flexibility and do not expect to make large extra repayments or refinance during the fixed term. They work particularly well when cash flow is tight and predictable repayments help with business planning.
