Bridging Loans to Buy at Auction Before You Sell

You can buy at auction before you sell your home, but only if your finance is lined up before the hammer falls. A bridging loan covers the gap between buying the new place and selling the old one, and for a FIFO mobile plant operator on a tight roster, the timing is the hard part.

Auction purchases are normally unconditional, with no cooling-off period and no finance clause, but check the contract and your state's rules. If you win, you are usually expected to pay the deposit on the day and settle on the date in the contract. That is why bridging loans for FIFO workers need to be sorted early, not after you have raised your hand.

What Is a Bridging Loan and How Does It Work for an Auction Purchase?

A bridging loan is short-term property finance that lets you buy a new home while you still own and owe money on your old one. APRA describes bridging finance as owner-occupied lending for people who plan to move their main home and, in the meantime, still have an existing owner-occupied loan. It expects the arrangement to be finished within twelve months.

Many lenders take security over both properties, but this varies by lender and product. Ask your broker how the loan is secured. You carry the old loan and the new one together until the old home sells, then the sale proceeds pay down the debt. Lenders set their own fees, rates and maximum loan to value ratio (LVR), so these differ depending on your deposit, equity and lender. A broker can compare options from the lenders on their panel.

The main trade-off is that you are carrying two homes at once. If the old home sells slowly or for less than you hoped, the debt stays higher for longer.

Why Auction Day Timing Is Tricky on a FIFO Roster

Auction timing is tricky because the date is fixed and your roster is not. A swing that lands on auction day, or a flight out the day after, can leave you with no time to sign papers.

The fix is to have your finance assessed before you bid. Ask for pre-approval so you know your ceiling, and set a firm limit you will not go past. You can read more on getting loan pre-approval before you pick an auction date. Pre-approval is not a promise of the final loan. The lender still values the property and checks your details before settlement.

If you will be on site, you can talk to your broker about bidding by phone or through an agent, and about signing documents electronically. Check the auction conditions with the agent well ahead of time.

How Do Lenders Assess a Bridging Loan Application?

Lenders assess a bridging loan by checking that you can afford the repayments on your income, not just on the sale of the old home. Under responsible lending rules, a loan is likely to be unsuitable if you could only repay it by selling your main home. That sale is presumed to cause substantial hardship unless the lender shows otherwise.

ASIC's guidance does name bridging loans as a case where selling an asset can form part of the plan. Even so, expect the lender to test the higher debt level. APRA's serviceability buffer is 3 percentage points above the loan rate, as confirmed in its 28 May 2026 update.

For mobile plant operators, base pay, rostered overtime and allowances are treated differently by different lenders. Your borrowing capacity can change a lot depending on which lender looks at your payslips. Our page on home loans for FIFO mobile plant operators explains how that income is often viewed.

A Worked Example: Buying at Auction With the Old Home Still Listed

Consider an operator who finds a house at auction while the current home is yet to be sold. The goal is to bid with confidence, so the operator speaks to a broker three weeks out.

The broker sets up a bridging structure and the lender values both homes. Say the combined peak debt is $900,000, a figure used purely for illustration. At the illustrative rate of 6.75% p.a., interest-only repayments on that amount would be about $5,063 a month ($900,000 x 6.75% / 12). That is the cost of carrying the debt while both homes are owned, before any other costs.

The operator wins the auction, pays the deposit and lists the old home straight away. It sells within the bridging period. The sale proceeds pay down the debt, and the loan falls to the end debt, which the operator then repays under a standard home loan. In this scenario, the operator avoided selling first and rushing into rental accommodation. The trade-off was a few months of heavy repayments and extra costs.

Your real figures will differ. Use a repayment calculator and ask your broker to run the numbers with your actual lender.

Bridging Loan Costs and Risks to Weigh Up First

The main costs of a bridging loan are interest on both debts, lender fees, and the usual buying costs such as stamp duty. Each lender sets its own fees and rates for bridging loans, so compare them closely.

The biggest risk is the old home not selling in time. What happens if the old home is unsold at the end of the bridging period depends on your lender's terms, so ask before you sign. Moneysmart says you can ask your lender for a hardship variation if you struggle with repayments. Talk to your broker early if things are slipping.

If a lender capitalises interest, unpaid interest is added to the loan balance, so you may owe more at the end. Ask each lender how interest is charged before you sign.

Tax and Land Tax Points When You Own Two Homes

Owning two homes for a short time can affect your capital gains tax and land tax, so speak to your accountant before you buy. The ATO says you may treat both homes as your main residence for up to 6 months if you meet its conditions. These include living in the old home for at least 3 months in the 12 months before selling it, and not renting it out in that time.

If the old home takes longer than 6 months to sell, part of the gain may be taxable. Land tax concessions for people who own two homes also differ by state, and they often do not apply if either home is rented. Check the rules in your state and get advice from your accountant.

When you sell, each owner will need a clearance certificate for the buyer at or before settlement. The ATO says they can take up to 28 days to process, so apply early.

Is There an Alternative to a Bridging Loan?

Yes. You can sell first, use an equity release loan, or buy with a larger deposit from savings. Each has a trade-off. Selling first removes the double debt but may leave you needing a place to live. Accessing equity can work if you have enough in your current home, but it adds to your debt. See equity release loans for FIFO workers for how that works.

A bridging loan is not for everyone. If the repayments on both homes would squeeze you, selling first can be the safer move, even if it feels slower.
