A polished proposal can still rely on favourable rent, growth, tax and finance assumptions. Review the numbers independently and separate facts, estimates and sales claims before committing.
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
Does the proposal still work when assumptions are replaced with evidence and downside cases?
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
- Independent evidence for price, rent, vacancy and ongoing costs
- Who prepared the growth forecast and what it assumes
- Finance terms, rate sensitivity and total cash required
- Tax estimates based on your actual ownership and income
- Commissions, referral relationships and incentives
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. Independent evidence for price, rent, vacancy and ongoing costs
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
When proceeding may be considered
The asset and numbers remain credible after independent checks and conservative modelling.
Renegotiate
The property may be suitable, but price, inclusions, finance or contract terms do not reflect the verified position.
Walk away
The case depends on unsupported growth, understated costs or pressure to sign before advice.
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.
| Decision path | What it may look like | Next evidence needed |
|---|---|---|
| When proceeding may be considered | The asset and numbers remain credible after independent checks and conservative modelling. | What must be verified before acting |
| Renegotiate | The property may be suitable, but price, inclusions, finance or contract terms do not reflect the verified position. | What must be verified before acting |
| Walk away | The case depends on unsupported growth, understated costs or pressure to sign before advice. | 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
- Treating projected tax benefits as investment return
- Using gross rent without vacancy, management, maintenance and owner costs
- Accepting a developer or promoter valuation as the only price evidence
- Allowing urgency to replace due diligence
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
What numbers should be independently checked?
Price, comparable sales, rent, vacancy, strata or owner costs, finance, depreciation claims and exit costs.
Does a high tax deduction make the proposal better?
A deduction may reduce part of a cost; it does not turn an overpriced or weak asset into a strong investment.
Can Andrew inspect the building?
The strategy review focuses on the financial, ownership, tax and cash-flow decision. Building, valuation and legal work require the relevant specialists.
