The Buffer Flip Strategy is Oliey Finance’s approach to directing an affordable cash surplus into a linked offset account. Developed by Fran Jerome in Cranbourne, it starts with your current income, actual expenses, existing commitments and emergency reserves.
Start with a surplus you can sustain
Banks subject to APRA’s requirements generally assess residential mortgage serviceability using a rate buffer of at least three percentage points above the loan rate. This is a lending assessment safeguard. It does not prove that the difference between the assessed and actual repayment is spare money in your household today. Circumstances may have changed since approval, and lender assessment methods differ.
Use a current budget to decide what, if anything, you can comfortably contribute. Keep sufficient funds available for expected expenses and emergencies. If there is no sustainable surplus, do not set a contribution simply because a lender previously assessed you at a higher rate.
How the Buffer Flip Strategy works
- Identify an affordable contribution. Review income, spending and reserves. Choose a contribution that remains practical when expenses rise or income falls.
- Check the loan and offset. Confirm the offset percentage, fees, access conditions and whether the linked loan is suitable for your needs.
- Model and review. Estimate the effect of contributions and withdrawals on interest and repayment progress. Review the plan when your income, spending, rate or goals change.
With a 100% offset, the balance generally reduces the amount on which interest is calculated. Building that balance can reduce interest and help you make faster progress, provided the loan terms and repayments support it. Withdrawing money reduces the offset benefit. The outcome depends on the actual balances, rates, fees and contributions over time.
A simple interest illustration
If a home loan has a $600,000 balance and a linked 100% offset holds $20,000, interest is generally calculated on $580,000. At an unchanged rate of 6% per year, maintaining that offset balance for a year would reduce interest by approximately $1,200 before fees and other effects. Actual interest is calculated under the lender’s terms and varies as the loan and offset balances change.
This illustration does not establish a particular payoff date. A personalised model should show contributions, withdrawals, rates, fees and repayment assumptions before estimating a loan-term reduction.
Frequently asked questions
Does loan approval mean I have extra money available?
No. Approval reflects a lender’s assessment at that time. Your contribution should come from a current budget and leave room for expenses and emergency reserves.
How many years could this save?
There is no standard result. The effect depends on your loan, actual offset balances, additional contributions, withdrawals, interest rates and fees. Fran can help compare scenarios using clearly stated assumptions.
Is this the same as making extra repayments?
Both can reduce interest, but the money is held differently. Offset funds remain in a separate linked account; extra repayments reduce the loan balance. Redraw access depends on lender terms. If you may later rent out the property, obtain advice from a registered tax practitioner before choosing a structure.
Do APRA’s buffer rules apply to every lender?
APRA’s prudential rules apply to authorised deposit-taking institutions. Non-bank lender requirements and individual assessment policies may differ.
What type of loan is needed?
Check that your loan offers a linked offset account and confirm whether it is full or partial. Compare any additional fees and rate differences with the expected benefit. Fixed-rate products may restrict offset features. Refinancing is not automatically necessary or worthwhile.
