Buying before selling is risky because bridging finance is assessed on serviceability (income), not the equity in your existing home, so owning a house outright doesn't guarantee approval. There's no cooling-off period at auction and no finance condition, so a successful bid commits you regardless. The biggest real cost is usually losing the ability to hold out for a better sale price once you're locked into a settlement date.
We've written a fair bit about downsizing — what it really costs, the stamp duty concessions, downsizer contributions, the tax rules when two homes briefly overlap. What we haven't covered is the bit that trips people up first: the order you do it in.
You went looking "just to see what's out there." And there it was — the single-level place near the grandchildren, the one that won't come up again for two years. Your house isn't sold. It might not even be listed.
Everything now hinges on one question: can you afford to own both, even briefly? This article is general information only — not personal, tax, legal or credit advice, and certainly not a recommendation to borrow.
Why doesn't owning it outright get you the loan?
Here's the part that genuinely surprises people.
Buyers in this position reach for bridging finance, which ASIC's MoneySmart defines simply as "short-term finance that covers the period between buying a new property and selling your existing property" (https://moneysmart.gov.au/glossary/bridging-finance, as at August 2026). The catch is how it's assessed. Bridging finance is judged on serviceability — whether you can meet the repayments — and that test is built around income. Your Age Pension, or the deliberately modest drawdown you've set up, reads as low income to that model. It doesn't much matter that there's a fully-owned house sitting behind it.
If that sounds familiar, it's the same mechanism we described in our article on why retirees get knocked back for credit cards: an income test applied to someone who is asset-rich and income-modest. Same logic, considerably larger stakes.
Bridging loans are also usually interest-only, and MoneySmart is blunt about what that means: the interest rate "could be higher than on a principal and interest loan," you "pay nothing off the principal during the interest-only period, so the amount borrowed doesn't reduce," and repayments increase once that period ends — which "may not be affordable" (https://moneysmart.gov.au/home-loans/interest-only-home-loans, as at August 2026). None of that is disqualifying. It's simply the shape of the product, and it's worth understanding before rather than after.
So you can own an unencumbered house worth a great deal and still be unable to borrow against it for three months. Not always — it depends on the lender and your circumstances — but often enough that the instruction is simple: find out what you could actually borrow before you go looking, not after you've fallen in love with something.
What is the auction problem?
This is the sharpest warning in the article, and it is not a matter of degree.
Cooling-off rights on residential property are set by each state and territory, and they are not the same thing as the cooling-off rights on financial products that we cover elsewhere. Buying by private sale, MoneySmart notes, generally gives you "a short cooling-off period in most states and territories" during which you can usually get out of the contract and recover most of your deposit by giving written notice — and the length of it varies by state. But at auction the position is categorical: "There's no cooling-off period if you buy at auction," which also means the sale is "not subject to finance or a building or pest inspection" (ASIC MoneySmart, https://moneysmart.gov.au/home-loans/buying-a-house and https://moneysmart.gov.au/glossary/cooling-off-period, as at August 2026). Check the position for private sales in your own state, because that part does vary.
Read that second half again, because it's the part people miss. Not subject to finance. If you're the successful bidder, you're committed — deposit paid, settlement date set, contract binding — whether or not your own house has sold, and whether or not the finance came through.
So, bluntly: if you haven't sorted your finance and your fallback before the auction, don't bid. Everything else in this article is a judgement call. That one isn't.
What are your options, roughly in order of risk?
Selling first and then buying is the safest by a distance, because you know exactly what you have. The cost is uncertainty about where you're going, and possibly renting for a while — our article on buying versus renting in retirement covers that trade-off. Negotiating a long settlement is the next-best: if you're buying by private treaty, a longer settlement gives your own sale time to happen, and it costs nothing but a cooperative vendor. Making the offer subject to sale — conditional on your own house selling — is realistic in a slow market, weak in a hot one, and no use at all at auction.
A deposit bond is worth understanding properly, because it is commonly misunderstood and the misunderstanding is expensive. MoneySmart's definition is precise: it "can be used in place of a deposit when a buyer exchanges contracts on a property, and it guarantees that the buyer will pay the full deposit by an agreed date" (https://moneysmart.gov.au/glossary/deposit-bond, as at August 2026). So it is a guarantee that you will pay the deposit — not a payment of it, and certainly not of the purchase price. It solves a timing problem at the front end and leaves both the deposit and the settlement money still owing.
Bridging finance is possible, but get a decision in principle in writing before you commit to anything, rather than proceeding on a hopeful assumption. Family help is very common and needs documenting properly, because an undocumented family loan is a problem stored up for later, both for Centrelink purposes and for the estate.
Equity release deserves a caution rather than a listing. Reverse mortgages and the Home Equity Access Scheme exist, and our articles on commercial reverse mortgages and on the Home Equity Access Scheme explain them; MoneySmart's own guidance on home equity release is worth reading first (https://moneysmart.gov.au/retirement-income-sources/reverse-mortgage-and-home-equity-release). They are long-term instruments with compounding costs, designed for a very different purpose. Using one to plug a three-month settlement gap is, in most cases, the wrong tool reached for under pressure.
What is the cost nobody models?
People in this situation worry about bridging interest. In my experience that's rarely what does the damage.
Here's what does. Once you're committed on the purchase, you've lost the ability to hold out on the sale.
Settlement is coming. You have one offer, and it's below what you hoped. Three months earlier you'd have said no and waited for a better one — but you can't, because you have a date to meet and a contract to honour. So you take it.
That discount routinely dwarfs every other cost in the transaction combined — the interest, the duty, the agent's fee, the removalists. It's also the one nobody puts in a spreadsheet, because it doesn't feel like a cost. It feels like bad luck.
It isn't bad luck. It's the predictable consequence of the sequence.
What about two homes at once — Centrelink and tax?
For a period you may own both properties, and that has consequences worth knowing in advance.
Only one place can be your principal home. The other is generally an assessable asset, which can affect your pension (Services Australia, https://www.servicesaustralia.gov.au/assets-test-for-age-pension) — our articles on the principal home and Centrelink, on Age Pension asset categories, and on holiday homes and second properties cover how that works. And once your house sells, the proceeds sitting in your account are assessable and deemed while they sit there. Tell Services Australia; our article on notification obligations covers what's required and when.
On tax, there is a rule that gives relief where two main residences overlap for a limited period, and our article on the six-month main residence overlap explains it. Read it — but read it knowing that it addresses tax, not cash flow. It does not fund anything, and it doesn't make the sequencing problem go away.
Two other things worth checking before you fix any dates: stamp duty concessions may be available to eligible pensioners downsizing, covered in our article on that, and if the proceeds are headed for a downsizer contribution there are timing conditions tied to the settlement date — see our articles on downsizer contributions and on how a downsizer contribution affects the assets test. Those conditions are why the settlement date is worth deciding deliberately rather than accepting whatever is offered.
What do the worked examples show?
Two illustrations of how the sequence, rather than the interest rate, decides the outcome. Both are illustrative only and not personal or credit advice; what any lender will actually do depends on its own assessment.
Consider Margaret, 74, a single homeowner with a house worth about $1.1 million, no mortgage, roughly $180,000 in super and an Age Pension. She finds a $780,000 single-level unit near her daughter and bids successfully at auction. There is no cooling-off period at auction and the sale is not subject to finance (ASIC MoneySmart) — so she is committed. Her broker then explains that bridging finance is assessed on serviceability, and that her pension plus a modest drawdown does not service a $780,000 bridge no matter that $1.1 million of unencumbered property sits behind it. On these facts the rational step was the one available a fortnight earlier: establish in writing what she could borrow, and only then decide whether to bid. Having bid first, her remaining choices are all worse than the one she gave up.
Now consider Tom and Helen, both 70, in the same position but buying by private treaty rather than at auction. Their house is worth around $950,000; the townhouse they want is $690,000. They negotiate a long settlement and make the offer subject to their own sale. When their first offer comes in at $890,000 — $60,000 under their hopes — they are able to decline it and wait, because nothing has committed them to a date. The second offer, some weeks later, is $935,000. On these facts, the $45,000 difference was bought entirely by the sequence, and it exceeds what a bridging facility over the same period would plausibly have cost. That is the trade the article is really about: the cheapest thing in this transaction is usually the ability to say no.
What should you do before you fall in love with a house?
Get more than one appraisal of your own place, and then discount what you're told. Ask a lender or broker what you could actually borrow and on what evidence — before you start looking, not after. Find out your state's cooling-off position for private sales, and take as given that an auction purchase carries none. Choose your sequence on purpose: if it's buy-first, know precisely how you'd fund a worst case in which your house takes six months to sell. And get the Centrelink and tax consequences of the overlap mapped before you commit, not after.
None of this is an argument against downsizing. Plenty of people do it and are glad. It's an argument for deciding the order deliberately — because the order is where the money is won or lost, and it's decided long before anyone signs anything.

Key takeaways
- Bridging finance is assessed on serviceability (your income), not on the equity in your existing home — an unencumbered house doesn't guarantee approval for a bridging loan.
- There is no cooling-off period if you buy at auction, and the sale isn't subject to finance or a building/pest inspection — a successful bid commits you regardless of whether your finance or your own sale has come through.
- A deposit bond guarantees you'll pay the deposit by an agreed date — it is not a payment of the deposit or the purchase price, and doesn't solve the settlement funding gap.
- The biggest cost in a buy-before-sell sequence is usually not bridging interest, but losing the ability to hold out for a better offer once a settlement date is locked in.
- Owning two properties at once has Age Pension and tax consequences: only one home is your principal residence, the other is generally assessable, and sale proceeds become assessable and deemed once received.
Frequently asked questions
Can I get a bridging loan if I own my home outright?
Not necessarily. Bridging finance is assessed on serviceability — whether you can meet the repayments from income — not on the equity in your existing home. An Age Pension or a modest drawdown can read as low income to that test, regardless of how much unencumbered property sits behind it.
Is there a cooling-off period if I buy at auction?
No. There's no cooling-off period if you buy at auction, and the sale is not subject to finance or a building or pest inspection. If you're the successful bidder, you're committed to the deposit and settlement date whether or not your own house has sold or your finance has come through.
What is a deposit bond and does it solve the funding gap?
A deposit bond can be used in place of a cash deposit when exchanging contracts, and it guarantees you'll pay the full deposit by an agreed date. It is a guarantee, not a payment — it solves a timing problem at the front end but leaves both the deposit and the settlement money still owing.
What's the biggest financial risk of buying before selling?
It's usually not the interest on a bridging loan — it's losing the ability to hold out for a better sale price. Once you're committed to a purchase with a settlement date, you can't afford to reject a low offer on your own home the way you could if nothing were locked in, and that discount often dwarfs every other cost combined.
