Smart ways to switch from fixed to variable rate

Your fixed rate period is ending and you're looking at what comes next.

Most lenders will automatically roll you onto their standard variable rate when your fixed term expires, and that rate is often higher than what new borrowers are being offered. For self-employed borrowers and working professionals around Rushcutters Bay, the difference between accepting that rollover rate and actively refinancing can be several thousand dollars each year. This article walks through when refinancing to variable makes sense, how the process works for self-employed applicants, and what to consider before you apply.

Why lenders increase your rate when fixed terms end

When a fixed rate period ends, your loan automatically converts to the lender's standard variable rate. That rate is rarely their most competitive offering. Lenders price their loans based on risk and acquisition cost. A borrower who has been with them for two or three years costs nothing to retain, so there's little commercial pressure to offer a sharp rate. New customers, by contrast, are expensive to attract.

Consider a professional in Rushcutters Bay who fixed at 2.1% three years ago. That loan might roll to a standard variable rate around 6.5%, while new variable loans are being written closer to 6.0%. On a loan amount of $800,000, that 0.5% difference costs an extra $4,000 each year. Refinancing to a lower variable rate means those savings continue for as long as you hold the loan.

Fixed rate break costs and timing your refinance

If your fixed rate period has already ended, there are no break costs. You can refinance your home loan at any time without penalty. If you're still within the fixed period, breaking the loan early usually triggers a cost calculated on the difference between your fixed rate and the current wholesale rate for the remaining term.

Break costs are unpredictable. If market rates have risen since you fixed, the break cost is often zero or minimal. If rates have fallen, the cost can be substantial. Most lenders will provide a break cost estimate over the phone, and it's worth checking this figure a few months before your fixed term ends. If the break cost is low enough that the monthly saving from a lower rate will recover it within six to twelve months, refinancing early can still make sense.

How refinancing works for self-employed borrowers

Self-employed applicants need to provide more documentation than PAYG employees, but the refinance process is otherwise identical. Lenders typically ask for two years of tax returns, two years of notices of assessment, and recent business activity statements. If your income has increased since your original loan was approved, that works in your favour. If it has decreased or become more variable, some lenders will still approve the refinance based on a longer income average or by giving more weight to recent trading conditions.

In our experience, self-employed borrowers around Rushcutters Bay often have more complex income structures involving trusts, companies, or multiple income streams. Not all lenders assess these structures the same way. One lender might add back depreciation and certain business expenses to calculate your serviceability, while another treats the same income more conservatively. A loan health check before you apply helps identify which lenders will assess your income most favourably and whether your current loan structure still suits your circumstances.

What to look for beyond the interest rate

A lower rate is the primary reason to refinance, but it's not the only feature that matters. Offset accounts, redraw facilities, and repayment flexibility all affect how much interest you pay over the life of the loan.

An offset account is particularly useful for working professionals who hold surplus cash for tax, irregular income, or upcoming expenses. Every dollar in the offset reduces the balance on which interest is calculated, and the savings compound over time. If you're holding $50,000 in an offset against an $800,000 loan at 6.0%, you're saving $3,000 each year in interest without losing access to that cash.

Redraw facilities allow you to access extra repayments you've made, but the terms vary. Some lenders limit how much you can redraw or impose processing times. If you're self-employed and your income fluctuates, the ability to make extra repayments during high-income periods and redraw during leaner months can improve cashflow without needing a separate line of credit.

Accessing equity when you refinance

If your property has increased in value since you took out the original loan, refinancing can also be an opportunity to access equity. This is common among Rushcutters Bay property owners looking to fund renovations, purchase an investment property, or consolidate other debts.

Lenders will typically allow you to borrow up to 80% of your property's current value without paying lenders mortgage insurance. If your property was valued at $1.2 million when you bought it and is now worth $1.5 million, that's an additional $240,000 in available equity at the 80% threshold. The equity can be drawn as cash at settlement or set up as a separate split within the loan structure, depending on how you plan to use it. If you're considering investment property expansion or debt recycling, structuring the equity correctly from the start makes the tax treatment clearer and gives you more flexibility later.

How long the refinance process takes

From application to settlement, refinancing typically takes four to six weeks. The timeline depends on how quickly you can provide documentation, how long the lender takes to assess the application, and whether a property valuation is required. Most lenders order an automated valuation first. If that comes back within their acceptable range, no physical inspection is needed. If the automated valuation is unclear or falls short, they'll arrange a physical appraisal, which adds another week or two.

For self-employed applicants, the assessment stage can take a few days longer, particularly if your income structure requires manual underwriting. Lodging complete documentation upfront speeds things up. That means tax returns, notices of assessment, business financials, and recent BAS statements all provided at the time of application, not in response to follow-up requests.

When refinancing to variable doesn't make sense

Refinancing isn't always the right move. If you're planning to sell the property within the next twelve months, the cost and time involved in refinancing may outweigh the interest saving. If your loan balance is low relative to the property value and you're already making significant extra repayments, the dollar saving from a slightly lower rate may not justify the effort.

Some borrowers prefer the certainty of fixing again rather than moving to a variable rate, particularly if they believe rates will rise further. If that's your view, compare the cost of fixing with your current lender against refinancing to a new lender and fixing there. The lowest fixed rates are rarely offered to existing customers, so refinancing to fix can still deliver a lower rate than staying put.

What happens if your loan application is declined

If your financial circumstances have changed since your original loan was approved, there's a chance your refinance application could be declined. This can happen if your income has dropped, your expenses have increased, or your credit file now shows missed payments or defaults.

A declined application doesn't prevent you from applying elsewhere, but it does appear on your credit file and may prompt questions from the next lender. Before applying, it's worth reviewing your credit file and running your income and expenses through a serviceability calculator to confirm the loan is affordable on paper. If your circumstances have changed significantly, it may be worth delaying the refinance until your income stabilises or your expenses reduce.

Refinancing when your fixed rate period is ending gives you control over what rate you pay and what features your loan includes. It's particularly relevant for self-employed borrowers and professionals in Rushcutters Bay, where property values have held firm and many households are managing multiple income sources or planning their next property move.
