A loan restructure can improve clarity, pricing and cash flow, but it cannot rewrite how borrowed money was actually used. The design should support both financial management and accurate tax records.
The useful question is not whether one option is universally better. It is whether it produces a stronger result for your income, debt, cash reserves, ownership position and next decision.
The decision to make
Can the debt be made cheaper, clearer and more flexible without mixing purposes or increasing risk?
A proper comparison starts from your position today. It then models what changes under each option. That means showing the cash required, debt after the decision, tax consequences, expected ongoing cash flow and what happens if the plan underperforms.
Generic rules are appealing because they are quick. They are also where expensive mistakes begin. Two people considering the same property can reach different answers because their income, existing assets, loan purpose, ownership, time horizon and capacity for risk are different.
What should be reviewed
- Purpose and transaction history of each loan and redraw
- Interest rate, repayments, term, fees and fixed-rate conditions
- Security allocation and exposure of each property
- Use of offsets, redraws and new splits
- Future purchases, private spending and repayment priorities
These items should be connected in one model. A choice that appears attractive for income tax may create more land tax, restrict finance or weaken cash reserves. A choice with the lowest monthly repayment may extend debt or make future transactions harder. The point of the review is to see the whole effect before acting.
Work through each input rather than relying on a rule of thumb
1. Purpose and transaction history of each loan and redraw
Document the current position, the proposed change and the source of every estimate. Then show how this item changes under each option and under the downside case. If the conclusion depends on an assumption that cannot be verified yet, make that dependency visible rather than treating it as fact.
2. Interest rate, repayments, term, fees and fixed-rate conditions
Document the current position, the proposed change and the source of every estimate. Then show how this item changes under each option and under the downside case. If the conclusion depends on an assumption that cannot be verified yet, make that dependency visible rather than treating it as fact.
3. Security allocation and exposure of each property
Document the current position, the proposed change and the source of every estimate. Then show how this item changes under each option and under the downside case. If the conclusion depends on an assumption that cannot be verified yet, make that dependency visible rather than treating it as fact.

This process matters because one uncertain input can change the result. If the leading option only works when every assumption is favourable, the comparison is not yet well supported. A useful model identifies the break-even point: the interest rate, rent, sale price, cost or holding period at which the result changes.
Three ways the answer can fall
Create clean splits
Different purposes can be separated prospectively and records remain traceable.
When refinance and change securities may be considered
Pricing or control improves enough to justify costs and the new structure supports the portfolio plan.
When leaving the loans unchanged may be considered
The tax history is complex and a proposed restructure adds cost without a material commercial benefit.
The scenarios are not predictions. They are decision tests. The strongest option should remain workable when the assumptions are made less favourable and should have a clear exit if circumstances change.

|---|---|---|

| When refinance and change securities may be considered | Pricing or control improves enough to justify costs and the new structure supports the portfolio plan. | What must be verified before acting |

Build an expected case and a downside case
Start with the expected income, finance costs, property expenses and transaction costs. Then test higher interest, lower income or rent, vacancy, unexpected works and a slower exit. The downside case should show how much cash is consumed, which reserve funds it uses and how long the position can be carried.
Tax belongs inside that model. It changes net cash flow, but a deduction does not remove an expense and a future concession does not solve a current liquidity problem. The timing of payments and tax outcomes can also differ, which is why an annual estimate alone can hide pressure during the year.
Common mistakes
- Believing a refinance converts private debt into investment debt
- Using one redraw for mixed personal and investment spending
- Cross-collateralising by default
- Extending the loan term and considering only the lower monthly repayment
Another mistake is starting with a product or structure and working backwards. Start with the decision, the facts and the outcome you need. Then compare only the options that are legally, financially and practically available.
Information to bring to a review
- Current property values, rents and recent property statements
- Loan balances, rates, repayments, offsets and redraw history
- Household or business income and fixed commitments
- Available cash and the minimum reserve you want to preserve
- Ownership entities, other taxable land and relevant trust or SMSF details
- The proposed property, sale, refinance or restructure information
- Your expected holding period and what would make you exit
Accurate inputs make the recommendation more useful. Where a number is uncertain, record the assumption and show how sensitive the decision is to it.
What a written recommendation should tell you
A useful recommendation does more than name an option. It should explain why that option fits the agreed facts, which alternatives were compared and which assumptions could change the answer. It should also identify the actions that must happen before commitment, who needs to perform them and the order in which they should occur.
The recommendation should distinguish strategy work from implementation. Your accountant or tax adviser may confirm tax treatment and reporting. Your broker or licensed credit adviser deals with credit assistance and loan products. Your solicitor or conveyancer handles the contract, ownership documents and legal risks. Valuers, building inspectors, property managers and buyer's agents may provide other evidence. Coordination matters because a technically correct answer from one discipline can still fail when it is disconnected from the finance, legal or cash-flow position.
The written advice can also identify a review trigger. A change in interest rates, income, property price, rent, contract terms or family plans may justify reopening the model before action. A decision document is most valuable when it shows both the personalised recommendation and the conditions under which it should be reviewed.
Frequently asked questions
Can I choose which part of a mixed loan I repay?
The tax consequences of mixed loans can be complex. Obtain advice based on the actual transactions before acting.
Does the security determine deductibility?
The use of borrowed funds is central; the property used as security does not by itself determine the outcome.
What records help?
Loan statements, settlement records, redraw histories, invoices and a timeline of how funds were used.
