Assisting an adult child into property: the decisions worth making carefully
The decision to assist an adult child into property is one that arrives with genuine emotional weight, and it warrants the same rigour applied to any significant financial commitment. The question is rarely whether to help — it is how to structure that assistance so that the generosity does not compromise the financial position that made it possible. We have seen both outcomes. The difference is almost always in the preparation.
Assess your own position first
No assistance to a child should be committed before a clear-eyed assessment of your own retirement position. That means quantifying your expected retirement income — superannuation, investment returns, Age Pension entitlement if applicable — against a realistic estimate of your spending needs, including an allowance for an extended life expectancy and unexpected health costs. A cash reserve for contingencies should also be accounted for. What remains after that assessment has been completed honestly is what is genuinely available to deploy.
The five principal structures
Once the capacity to assist has been established, there are five approaches worth considering, each with different implications for both parties.
A cash gift provides immediate, unconditional support. It requires no documentation and places no ongoing obligation on the recipient. It also means the funds are gone permanently — there is no recovery mechanism if circumstances change. Only amounts that can be released without consequence to your own position should be gifted.
An interest-free or low-interest loan preserves the capital and allows for its return if needed. It must be documented formally as a loan — not doing so creates ambiguity that courts and families both find difficult to resolve, particularly in the event of a relationship breakdown or death. The loan should specify repayment terms and be reviewed periodically.
A guarantor arrangement allows a child to avoid lenders mortgage insurance by securing part of their borrowing against your property. It is a widely used structure, but the exposure is real — in the event of default, the lender will pursue the guarantor. In the worst case, the guarantor's property can be called upon. This is a commitment that should be entered with complete clarity about the downside.
Joint borrowing and co-ownership is appropriate where you have substantial equity and the appetite to share both the mortgage obligation and the asset. It requires legal documentation of the ownership structure and the exit mechanism — specifically, how and when your interest in the property is transferred to your child. Capital gains implications attach to this structure and warrant separate consideration.
Practical assistance — allowing a child to live with you rent-free while they save, or assisting with the application process for a First Home Owner Grant — has no financial downside for the parent and can materially shorten the time required to reach an independent deposit. It is often overlooked in favour of more complex arrangements.
Centrelink gifting rules
For those receiving a full or part Age Pension, the gifting rules are specific. You may gift $10,000 in any financial year, and no more than $30,000 across any rolling five-year period, without affecting your pension entitlement. Amounts above these thresholds are treated as deprived assets for five years — they continue to be assessed as your assets for both eligibility and deeming purposes. A loan to a child is treated as an asset for pension purposes and will affect the deeming calculation accordingly.
Family dynamics
Where there is more than one child, the terms of any assistance — and the intention regarding equity across siblings — should be made explicit before any commitment is made. Assumptions about what will be offered to others, or what provision will be made in an estate, have a habit of diverging from reality in ways that damage relationships long after the property transaction has been forgotten.
It is also worth noting that a property handed to a child outright, even where the financial capacity exists, removes the experience of managing a significant financial commitment. That experience has value that is difficult to replace after the fact.
If you would like to work through the most appropriate structure for your circumstances, we are available to do so.
