Bridging Loans for Auction Buyers: Common Mistakes

Bridging finance can let you bid at auction before your current home has sold, but only if your exit plan holds up.

Auction contracts are usually unconditional. That means you can't make the purchase subject to selling your home. For nurses and midwives working rosters, the timing pressure is real. This article covers the mistakes that cause the most trouble and how to avoid them.

What Is Bridging Finance and How Does It Work for Auction Buyers?

Bridging finance is short-term lending that covers the gap between buying a new home and selling your existing one. APRA describes it as owner-occupied lending for borrowers who intend to transfer their principal place of residence and, in the meantime, still have an existing owner-occupied loan. APRA expects the arrangement to be completed within twelve months of the loan starting.

For an auction buyer, this means you can bid without waiting for a sale. You still need to settle the purchase on the contract date, so the finance must be lined up before you raise your hand. Talk to a broker about bridging loans for nurses well before auction day, not after the hammer falls.

Mistake One: Bidding Before You Have Finance Approved

The most common mistake is bidding without approval in place. A winning bid at auction is a binding contract, usually with no finance clause and often with a deposit due on the day.

Getting loan pre-approval first tells you your ceiling. For bridging, lenders look at your existing loan, the new loan and your income together. Lenders must also make reasonable inquiries and check your financial situation under responsible lending laws. A broker also has a legal duty to act in your interests.

Bridging applications can involve more documents and checks, so start early. Pre-approval is also not a promise of final approval, as the lender will still value the property.

Mistake Two: Ignoring How Lenders Assess Your Repayments

Lenders must make reasonable inquiries and be satisfied you can meet repayments without substantial hardship. ASIC guidance says repayments should in most cases come from income rather than the sale of an asset. It recognises that bridging loans can be an exception, because the sale of your existing home may form part of the repayment plan.

Under the National Consumer Credit Protection Act, if you could only meet your obligations by selling your home, it is presumed you could do so only with substantial hardship, unless the lender proves otherwise.

Lenders still apply a serviceability buffer of at least 3 percentage points over the loan rate. As of APRA's 28 May 2026 update, that buffer stays at 3 percentage points.

One useful point: APRA's debt-to-income limits, which started on 1 February 2026, exempt bridging finance for owner-occupiers. Check with your broker how your chosen lender applies this. To see where you stand, use the borrowing capacity page.

Bridging Loan Example: Buying at Auction Before Selling

Here is an illustrative example at 6.75% p.a. Consider a registered nurse and a partner who plan to upgrade. They are keen on a home going to auction in three weeks. Their current home is not yet listed.

The situation: They have a home loan of $400,000 and want to borrow $800,000 for the new property. During the bridging period they would hold both debts. Their broker explains that the lender will assess the peak debt, which is both loans together.

The solution: The broker arranges approval before auction day and the couple set a sale plan. They list the existing home soon after the auction win, with a set bridging period of six months.

The outcome: Their current home sells in the fourth month. At 6.75% p.a., interest on the $800,000 is about $4,500 a month if it is interest only, or about $18,000 over four months. Interest on the existing $400,000 adds about $2,250 a month, or about $9,000 over the same four months. That is about $27,000 in interest across both loans, before fees. The sale proceeds repay the existing loan and part of the new one, leaving a smaller end debt on the new home.

Your own figures will differ with the lender, the rate and your deposit. Run numbers through a lender calculator and ask your broker for the full costs, including fees and any interest being capitalised, which means added to the loan balance.

What Happens If Your Home Does Not Sell in Time?

If your home has not sold when the bridging period ends, you may need to extend, refinance or reprice the debt, depending on the lender. What happens depends on your loan terms, so ask your lender before you sign.

APRA expects banks to monitor these loans over the twelve months. The risk is that you carry two debts for longer than planned. Interest keeps running, and a falling sale price leaves a bigger end debt. Price your home to sell and set a fallback, such as refinancing the debt to a standard loan.

If repayments become hard, ASIC's Moneysmart says you can ask your lender for a hardship variation, and the lender must respond within 21 days of receiving the information it needs.

Tax Points to Raise With Your Accountant

The ATO says you can treat both homes as your main residence for up to 6 months when buying before selling, if certain conditions are met. These include living in the old home for at least 3 months in the 12 months before it sells, and not using it to earn rent. If the sale takes longer than 6 months, part of the gain on the old home may be taxable.

If you sell the old home, you need to give the buyer a clearance certificate. The ATO says applications can take up to 28 days, so apply early. Land tax transitional rules also differ by state and territory. Speak to your accountant about how these rules apply to you, as outcomes depend on your circumstances.

Is a Bridging Loan the Only Option?

No. Alternatives include selling first, using equity in your current home, or asking about a longer settlement. Each has a trade-off.

Selling first removes the double debt but may mean renting while you search. An equity release loan can fund a deposit, though it adds to your debt on your current home. Your broker can compare these with buying your next home in mind.

Bridging suits auction buyers because the timing is fixed, but it can cost more than a standard loan depending on the lender.
