A loan split is a separate account or portion of a lending facility. Investors might use one to keep a deposit borrowing separate from their existing home loan, or to hold fixed and variable portions separately. These are different objectives. Before asking a broker to create a split, explain what money will be used for and what flexibility you need.
Through our finance and lending referral service, you can speak directly with an independent broker about available structures. This guide is a meeting checklist, not a recommendation to borrow or a tax strategy. For the broader purchase context, read using equity to invest.
Separate purpose from pricing
Ask whether the proposed splits separate borrowing purposes, interest-rate types, or both. An account labelled 'investment' does not make all its interest deductible. The ATO explains that the use of borrowed money matters, including later redraws for private spending. Your accountant needs the transaction history, not just the lender's account labels.
Nor does a split automatically mean separate security. Multiple accounts can remain secured by your home or by several properties together. Request a diagram showing the borrower, each loan, the amount, the intended use and the security supporting it. Have your broker explain what would happen if you sold one property or changed lenders.
Questions about getting the money to its destination
- Will the new borrowing go directly to settlement, or pass through another account? What records should I keep for every transfer?
- Can the deposit and purchase-cost borrowing be separated from private spending before funds are drawn?
- Which split has an offset account, and what fees or restrictions apply to it?
- What happens to loan purposes and records if I redraw, refinance, consolidate accounts or repay part of a mixed-purpose loan?
- Does each split have its own repayment, minimum balance, term and fixed-rate break-cost exposure?
A hypothetical tracing problem
Imagine a borrower draws funds for an investment deposit and later uses the same loan's redraw for a personal car. The account is now associated with different uses. Keeping a spreadsheet is useful, but it does not change the underlying transactions. The ATO describes apportionment requirements for mixed private and rental borrowings; ask an accountant to apply those rules rather than choosing which portion a repayment should reduce yourself.
This example illustrates record keeping only. It does not establish that any particular interest expense is deductible. Avoid moving money simply to 'clean up' the structure before getting advice: a new account or refinance may not undo the history.
Agree on a practical handover
Before proceeding, ask for the proposed structure in writing, a comparison of costs and a list of documents your accountant needs to review. Save loan contracts, drawdown statements, settlement statements and evidence of the destination of funds. Check the account setup after settlement against the agreed plan, including offset links and direct-debit instructions.
A final question
Does splitting the loan increase borrowing capacity?
Not by itself. Capacity still depends on the lender's assessment of income, expenses, liabilities and security. Ask your broker to distinguish an administrative split from a new credit application and to explain the assessment involved.
