Downsizing sounds straightforward: sell the big family home, buy something smaller, and pocket the difference. But the reality is considerably more complex. The difference between the sale price and the purchase price is not the amount available to spend. It is the starting point for a series of calculations that many Australians only discover after they have already committed to moving.
The most common downsizing calculation goes like this: sell the family home for $1.2 million, buy a smaller property for $800,000, and $400,000 becomes available for retirement. It is a number that appears in countless retirement conversations.
It is also not the amount that actually ends up available.
Between selling one property and purchasing another, a series of costs reduces that apparent windfall. How much depends on the state or territory, the property prices involved, and individual circumstances — but the reduction is always significant.
The following is an illustrative example only. Costs vary considerably by state, property price, circumstances and service providers. It is intended to show the types of costs involved — not to represent the costs that apply in any specific situation.
This example is illustrative only. Stamp duty varies significantly by state and territory. Agent commissions, legal fees and moving costs vary by location and provider. Always obtain specific quotes and professional advice before making financial decisions based on downsizing.
The difference between $400,000 and $300,000 is not trivial. For retirement planning purposes, it is a significant gap — and yet many Australians begin planning based on the headline figure rather than the net figure.
The first step in any serious downsizing analysis is calculating every cost, not just the price difference.
Despite the transaction costs, downsizing can genuinely improve a retirement financial position — for a number of reasons that go beyond the lump sum released.
A smaller, less expensive property typically costs less to maintain, insure, heat and cool. Rates may be lower. Garden maintenance may be reduced or eliminated. For many retirees, the annual saving in ongoing costs is as significant over a decade as the lump sum released at the point of sale.
The freed capital — properly invested — can also generate income. A $300,000 sum invested in a diversified portfolio earning a modest 5% generates $15,000 per year. That is before any drawdown of the capital itself.
The Retirement Calculator at wealthlorraine.com allows you to model what an additional lump sum of capital could mean for your retirement income across different scenarios — a useful starting point before making any decisions.
One of the most powerful — and underused — aspects of downsizing in Australia is the ability to make a downsizer contribution to superannuation from the sale proceeds.
As of the time of writing, the key rules are as follows. Always verify current rules directly with the ATO before acting, as rules can change:
Superannuation rules, contribution caps and eligibility requirements change over time. Always verify current rules directly with the Australian Taxation Office before making any contribution decisions. The information above reflects rules as understood at the time of writing and does not constitute financial advice.
For eligible Australians, the downsizer contribution represents a significant opportunity to move money into the superannuation environment — which offers tax-advantaged investment returns in retirement phase. As we explored in How Much Super Should You Have at Your Age?, the tax treatment of assets inside super in retirement can be considerably more favourable than holding equivalent assets outside super.
Perhaps the most misunderstood aspect of downsizing is its interaction with the Age Pension assets test.
Under current Australian rules, your principal home is exempt from the Age Pension assets test. This means that a retiree living in a $1.2 million home may be eligible for the Age Pension in circumstances where a retiree with $1.2 million in investable assets would not be.
When a home is sold and the proceeds become cash or investments, those proceeds are generally counted under the assets test. This can reduce or eliminate Age Pension entitlements that existed while the property was the principal residence.
There is a temporary exemption for sale proceeds when the intention is to purchase another principal residence. Services Australia currently provides a 12-month exemption period in certain circumstances — but this is subject to rules and conditions. Always verify current rules directly with Services Australia before making decisions.
The practical implication: a retiree receiving a full or partial Age Pension who sells their home to downsize could find their pension reduced or cancelled if the net sale proceeds push their assessable assets above the relevant threshold. The financial benefit of downsizing must always be modelled alongside the Age Pension impact — not separately from it.
This is explored further in The Biggest Home Ownership Myth About the Age Pension.
There is another side to this that spreadsheets cannot measure.
Your home affects your everyday life. A large family home may have wonderful memories attached to it. But it may also mean stairs that become increasingly difficult, a large garden requiring constant maintenance, rooms you rarely use, high maintenance expenses, distance from medical services, distance from children or grandchildren, and dependence on a car.
A well-planned move could provide something considerably more valuable than extra investment capital: freedom.
This is another common trap. Selling a large suburban home doesn’t guarantee you’ll release significant capital. A smaller apartment in a highly desirable coastal or inner-city location could cost almost as much — or even more.
Then there may be body corporate or strata fees, special levies, higher insurance costs, parking costs and facility fees. A $750,000 apartment with $8,000 per year in strata fees and a parking space costs meaningfully more to own over a decade than the purchase price alone suggests.
The right comparison is not house price versus apartment price. It is total cost of ownership across the retirement period you are planning for.
There is no universal answer. But these six questions provide a useful framework for thinking it through:
There is a tendency in retirement planning to reduce everything to dollars. But consider two scenarios.
Option A: Stay in a $1.2 million home that requires constant maintenance and leaves little money available for travel and experiences.
Option B: Move into an $800,000 home you love, reduce ongoing expenses and release capital that gives you greater financial flexibility.
Option B may look compelling. But change the circumstances: the $800,000 property has large strata fees, is further from family, and selling your existing home reduces an Age Pension entitlement. Suddenly, the calculation looks different.
That is why there is no universal answer — and why the decision deserves a thorough, personalised analysis rather than a quick back-of-envelope calculation.
