A fixed rate locks in your repayments for a set period, but whether that suits you depends less on where rates are heading and more on where you are in your business cycle.
Business owners rarely have the same financial profile from one year to the next. Income fluctuates, tax structures change, and the way lenders assess your borrowing capacity shifts depending on how long you have been trading. A fixed rate loan that works when you are buying your first property might not suit you when you are refinancing three years later with a restructured business or expanding into investment.
When You Are Buying Your First Property as a Business Owner
Your income documentation matters more than your deposit size when you are self-employed. Lenders typically want two full years of financials, and if you are still building your trading history, you will face tighter assessment and possibly a higher interest rate.
Locking in a portion of your loan during this stage protects your cashflow while your business is still establishing itself. If your income is still variable or you are reinvesting heavily, fixed repayments give you certainty during a period when your tax returns might not reflect your actual earning capacity. Consider a buyer who secured pre-approval six months into a new financial year but had only one full year of trading history. The lender approved the loan but applied a loading to the rate. Fixing 60% of the loan for three years meant predictable repayments while the business matured, and the variable portion allowed extra repayments as income increased without penalty.
The outcome was stable budgeting during a growth phase, and when the fixed period ended, the business had two additional years of financials and qualified for a lower rate on refinancing.
Fixed Rates When Your Income Structure Changes
Business owners often shift between sole trader, partnership, company, and trust structures as they grow. Each change affects how lenders assess your income, and in some cases, how much they will lend you.
If you are restructuring, a fixed rate might lock you into a loan that no longer suits your borrowing capacity once the change is complete. A variable rate or split loan gives you the option to refinance without break costs when your financials improve. On the other hand, if you are moving from a high-income year into a period of reinvestment where your taxable income will drop, fixing before that happens can secure your current rate based on stronger financials.

When You Are Expanding Into Investment Property
Once your owner-occupied loan is established, adding an investment property changes your debt structure and how lenders view your application. Interest on investment loans is tax-deductible, so the way you structure your rates affects both your repayments and your tax position.
Many self-employed investors fix their owner occupied home loan and keep their investment loan variable. The fixed portion provides stability for the property you live in, while the variable investment loan allows you to make extra repayments from business income during strong trading periods and claim the interest each year without restriction. Others do the reverse, fixing the investment loan if they expect rates to rise and want to lock in the deduction at a known amount.
The choice depends on your cashflow cycle. If your business generates uneven income, a variable rate on your investment loan lets you pay down debt when you have surplus without being penalised. If your income is steady and you want to forecast your tax position accurately, a fixed investment loan gives you a consistent deduction.
Using Split Loans to Match Your Business Cycle
A split loan divides your borrowing between fixed and variable portions, and it suits business owners who need both certainty and flexibility. You can fix the portion that covers your baseline expenses and keep the rest variable to absorb extra repayments during profitable months.
The split does not need to be equal. Some business owners fix 70% and keep 30% variable. Others reverse it. The ratio should reflect how predictable your income is and whether you are likely to sell, refinance, or restructure within the fixed period. If you expect to access equity or consolidate debt in the next few years, a higher variable portion reduces the risk of paying break costs when your circumstances change.
What Happens When Your Fixed Rate Ends
When your fixed period expires, your loan automatically reverts to the lender's standard variable rate unless you take action. That revert rate is often higher than the current advertised variable rate, and it is almost always higher than the rate you could access by refinancing or renegotiating.
Self-employed borrowers should review their loan at least three months before the fixed term ends. Your income documentation may have improved since you first borrowed, or your loan-to-value ratio may have dropped due to property price growth or principal repayments. Both factors can qualify you for a lower rate, either with your current lender or a new one. If you have built equity, you may also be in a position to remove Lenders Mortgage Insurance or access funds for further investment.
Refinancing at this point is common, but it requires current financials. If your most recent tax return shows lower income due to business reinvestment or restructuring, you may need to wait or provide additional documentation to support your application.
Choosing a Fixed Rate Based on What You Plan to Do Next
The value of a fixed rate is not in predicting where the market is going, but in knowing what you need your loan to do. If you are about to take on more debt, restructure your business, or reduce your hours, a fixed rate might limit your options. If you are entering a stable income phase and want to remove uncertainty from your budget, it provides that.
Self-employed borrowers benefit from keeping their loan structure aligned with their business strategy. If you are planning to expand, sell, or wind down in the next few years, a variable rate or a shorter fixed term keeps your options open. If you are holding steady and want to focus on building equity without worrying about rate movements, a longer fixed term suits that approach.

Frequently Asked Questions
Should I fix my home loan rate as a self-employed business owner?
It depends on your business cycle and income predictability. A fixed rate provides repayment certainty during periods of variable income or business growth, but may limit flexibility if you plan to restructure, refinance, or access equity soon.
What is a split loan and when does it suit self-employed borrowers?
A split loan divides your borrowing between fixed and variable portions. It suits business owners who need stable repayments for budgeting but also want the flexibility to make extra repayments during profitable periods without penalty.
What happens when my fixed rate period ends?
Your loan reverts to the lender's standard variable rate, which is often higher than current advertised rates. Review your loan three months before expiry to refinance or renegotiate based on improved income documentation or equity position.
Should I fix my investment loan or my owner-occupied loan?
Many self-employed investors fix their owner-occupied loan for stability and keep their investment loan variable to allow extra repayments and maintain flexibility for tax planning. The right approach depends on your cashflow cycle and tax strategy.
Can I refinance before my fixed rate ends without penalty?
You can refinance, but you will likely pay break costs if you exit a fixed rate early. The amount depends on how much time remains and whether rates have moved since you fixed. A higher variable portion in a split loan reduces this risk.
