You can refinance your home loan to add features that weren't included in your original product.
An offset account sits alongside your mortgage and reduces the interest you pay on the outstanding balance. If you have $30,000 sitting in an offset and owe $400,000 on your loan, you only pay interest on $370,000. The full loan balance remains, but the daily interest calculation treats the offset balance as though it's sitting against the debt. For anyone running a business or managing variable income, that structure gives you access to cash when you need it without touching the loan itself.
Why self-employed borrowers refinance for offset accounts
Self-employed income moves in cycles, and an offset account lets you park surplus cash during strong months without locking it away in the loan.
Consider a contractor who invoices $80,000 in one quarter and $30,000 in the next. Without an offset, extra repayments made during the high-earning period might be accessible through redraw, but redraw isn't guaranteed and some lenders restrict how often you can pull funds back out. With an offset, the $20,000 surplus from the strong quarter stays liquid. You can transfer it back to your operating account when invoices slow down, and the interest saving continues while the money sits there. That flexibility matters when your income doesn't arrive in neat fortnightly parcels.
How refinancing to add features works
You apply to a new lender or negotiate with your current one to move onto a product that includes the offset account or redraw facility you want.
The refinance process involves a credit assessment, a property valuation, and discharge of your existing loan once the new one settles. Most lenders will value your property as part of the application, and if your equity position has improved since you first borrowed, you might also access a lower rate or remove lender's mortgage insurance from the equation. The offset account typically comes as a standard feature on variable loans, though some lenders charge a slightly higher rate or an annual package fee to include it. Fixed rate loans rarely offer offset accounts, so if you're coming off a fixed rate period, moving to a variable product with offset is a common next step.
Offset accounts compared to redraw facilities
An offset account is a separate transaction account linked to your loan. A redraw facility lets you withdraw extra repayments you've already made into the loan itself.
Both reduce interest, but access works differently. With redraw, you're pulling money back out of the loan, and the lender controls how and when you can do that. Some lenders allow unlimited redraws online, others require a phone call or charge a fee, and a few restrict redraw entirely if you've made certain changes to the loan. An offset account is your money in your account. You move it in and out as you would with any transaction account, and the lender has no say in the matter. For tax purposes, that distinction also matters. If you've claimed interest deductions on an investment loan and then redraw funds for private use, you can muddy the deductibility. With an offset, the loan balance never changes, so the deduction stays intact.
What lenders look for when you refinance
Income verification, equity in the property, and your current repayment history.
If you're self-employed, expect to provide tax returns, business financials, and BAS statements covering the most recent two years. Lenders want to see that your income supports the loan amount and that you've been making repayments on time. The property valuation determines your loan-to-value ratio, which affects whether the lender will approve the refinance and what rate they'll offer. If you've paid down the loan or the property has increased in value, your equity position improves and the application becomes more straightforward. In our experience, borrowers who've been in the same loan for three or four years often find they've built enough equity to remove any LMI component and access a product with features they couldn't originally qualify for.
Refinancing to release equity and add offset together
You can combine a refinance for features with a withdrawal of equity if the numbers support it.
Say you owe $320,000 on a property now valued at $500,000. That gives you $180,000 in equity, and most lenders will let you borrow up to 80% of the property value without LMI, which is $400,000. You could refinance to a loan of $380,000, add an offset account, and walk away with $60,000 in cash for a deposit on an investment property or to cover business expenses. The offset account then gives you somewhere to hold any surplus income while you manage the larger loan balance. This approach works well when you're consolidating other debts or moving funds into a structure that improves tax outcomes, but the numbers need to stack up against your income and the rental yield or business return you're chasing.
How much offset activity actually saves on interest
The saving depends on the average daily balance sitting in the offset account and the interest rate on your loan.
If you're paying 6% on a $400,000 mortgage and you keep $40,000 in an offset year-round, you'll save around $2,400 in interest over twelve months. That's $40,000 multiplied by 6%, with the saving compounding as the loan balance reduces over time. The actual benefit increases if you use the offset strategically, parking business income, rental payments, or tax refunds there until you need them. We regularly see clients with offset balances that fluctuate between $10,000 and $60,000 depending on the season, and even with that variation, the interest reduction adds up. The key is keeping the account active and using it as your primary transaction account so everyday funds contribute to the offset balance rather than sitting in a separate savings account earning minimal interest.
When refinancing for features makes sense
When the interest saving or cash access outweighs the cost of moving loans.
Refinancing incurs discharge fees from your current lender, application fees or valuation costs with the new one, and sometimes legal fees if there's a change in title or security. Those costs typically sit between $800 and $1,500 for a straightforward refinance. If adding an offset account will save you $2,000 or more per year in interest, or if the flexibility helps you avoid drawing on a business overdraft at 9%, the move pays for itself quickly. On the other hand, if your loan balance is small or you're planning to sell the property within a year, the setup cost might not justify the switch. A loan health check helps you weigh the cost against the benefit and identify whether there are other rate or feature improvements worth chasing at the same time.

Frequently Asked Questions
Can I refinance just to add an offset account?
Yes, you can refinance to move onto a loan product that includes an offset account even if you're not changing your loan amount or lender. The process involves a credit assessment and property valuation, and the offset account is typically available as a standard feature on variable rate loans.
How much does it cost to refinance and add features?
Refinancing usually costs between $800 and $1,500, including discharge fees from your current lender and application or valuation fees with the new one. Some lenders also charge a higher rate or annual package fee for loans that include offset accounts.
What's the difference between an offset account and redraw?
An offset account is a separate transaction account you control, while redraw lets you withdraw extra repayments already made into the loan. Offset gives you unrestricted access to your funds, whereas redraw is controlled by the lender and may have fees or restrictions.
Do I need equity in my property to refinance for an offset?
You don't need additional equity to refinance for features alone, but lenders will assess your loan-to-value ratio as part of the application. If you've built equity since your original loan, it can improve your rate and make approval more straightforward.
Can I release equity and add an offset in the same refinance?
Yes, you can combine both if your equity position supports it. Most lenders allow you to borrow up to 80% of your property value, so if you've paid down the loan or the property has increased in value, you can withdraw cash and move onto a product with an offset account at the same time.
