A split home loan divides the debt into separate loan accounts or portions, commonly one fixed and one variable. It can be useful for borrowers who want some protection from rate changes without giving up all flexibility, but the split percentages should be linked to your actual cash-flow plan.
- Size the variable portion around offset needs
- Use fixed debt for repayment certainty
- Check extra repayment limits
- Review the structure at fixed-rate expiry
- Keep each split’s purpose clear
Match the variable split to your cash
If you expect to keep $100,000 in an offset, there may be little value in fixing so much of the loan that the variable balance is smaller than the offset you plan to hold.
The offset works most effectively when it is linked to a loan balance large enough to use the available cash.
Use the fixed portion for certainty
The fixed split can provide a known repayment on part of the debt during the fixed period. That can reduce the impact if variable rates rise.
However, extra repayment caps and break costs still apply to the fixed portion.
Review when the fixed term ends
At expiry, the fixed split will usually revert to a variable rate unless a new arrangement is made. That is a natural time to review the full structure, remaining loan term and competing lender options.
Do not allow a well-designed split to become an accidental, outdated structure years later.
Frequently asked questions
Can I split an existing loan?
Often yes, subject to lender product options and any fixed-rate implications.
Does each split have a separate repayment?
Usually each account has its own scheduled repayment and statement.
Can I have multiple splits?
Many lenders permit several splits, which can be useful for different purposes, but complexity should have a reason.
