A property purchase can look comfortable using today’s income and become much tighter when work or family circumstances change. If parental leave, a new job, self-employment, retirement or reduced hours are ahead, the decision should be tested against the transition—not only the latest payslip.
This does not automatically mean you should delay. It means the income change must be treated as part of the property decision rather than an issue to solve after settlement.
Identify the change precisely
Record the expected date, duration and range of income. Separate confirmed changes from possibilities. A signed employment contract, approved parental leave arrangement or planned retirement date carries different weight from a general intention to change careers.
Also identify secondary effects: bonuses may stop, childcare or commuting costs may change, business expenses may rise, or employer super contributions may differ.
Build a transition cash-flow view
Prepare monthly household cash flow for three periods:
- Before the change: current income, saving rate and existing commitments.
- During the transition: reduced or uncertain income, one-off costs and available leave or savings.
- After the change: the realistic ongoing position rather than the best-case income.
Add the proposed property’s rent, repayments, management, insurance, rates, strata, maintenance and vacancy allowance. Keep the expected tax position separate from the cash moving through the bank account.
Review borrowing before changing employment
Lenders assess income evidence and employment circumstances under their own policies. A probation period, new business, variable commissions or planned leave may affect the information required or the timing of an application. Ask your broker or lender to assess the actual circumstances rather than assuming an earlier pre-approval will remain unchanged.
Do not change or withhold material information to preserve an approval. Confirm credit and documentation questions with the appropriately authorised broker or lender.
Preserve liquidity through the change
A larger deposit may reduce borrowing but also consume the cash needed during a lower-income period. Compare the interest effect with the value of retaining an accessible buffer. Consider transaction costs and known property work as well as the deposit.
Be careful with redraws, company money and mixed-purpose accounts. How borrowed funds are used can affect the tax analysis and required records.
Consider ownership without chasing the highest deduction
If one partner’s income will fall, it may be tempting to make the ownership decision using a single year’s tax result. Ownership also affects control, land tax, future income, capital gains, finance and estate planning. A temporary income change should be considered within the expected holding period.
Stress-test the period with the least flexibility
Ask what happens if the income change lasts longer, the new role pays less, rent starts later or repairs arise. The decision does not need to survive every imaginable event, but it should not depend on every transition assumption being perfect.
Questions to resolve before committing
- What income evidence will the lender require?
- How much cash remains after deposit and costs?
- What is the property’s cash requirement during the lower-income period?
- Which expenses can be reduced if the transition is longer?
- Does the purchaser still make sense over the full holding period?
- Will this purchase restrict the next home, family or business decision?
Frequently asked questions
Should I buy before changing jobs?
There is no universal answer. Compare credit timing, employment evidence, the cash-flow transition and whether the purchase remains appropriate after the change.
Can I rely on a future salary increase?
Use confirmed information where possible and test a lower outcome. A forecast increase should not be the only reason the holding cost appears manageable.
Does parental leave mean I cannot invest?
Not automatically. The relevant questions include duration, household income, benefits, expenses, cash reserves, loan assessment and the property’s holding cost.
