Top tips to use bridging finance for auction properties

Auction properties move on their own timeline.

When you're working in a law firm, you see it regularly: a buyer finds the right property at auction, but their current home hasn't sold yet. The settlement period on an auction purchase is typically 30 to 45 days, and that timeline isn't negotiable. Bridging finance covers the gap between buying and selling, allowing you to secure the property without waiting for your sale to settle first.

How bridging finance works for auction purchases

Bridging finance is a short term loan secured against your current property. The lender advances funds to complete the auction purchase, and you repay the loan once your existing property sells. Most bridging periods run between three and six months, though 12 month terms are available if your sale strategy requires more time. Interest is typically capitalised, meaning it's added to the loan balance rather than paid monthly, and you service only your existing mortgage until the bridge is repaid.

Consider a legal assistant who wins an auction in Newtown with a 42-day settlement. Their current unit in Ashfield is listed but hasn't sold. A bridging loan allows them to settle the Newtown property on time, with the Ashfield sale proceeds used to close the bridge once that transaction completes. The bridging loan amount covers the new purchase price, plus capitalised interest for the bridging period, minus any deposit already paid.

Bridging loan LVR and security requirements

Lenders assess bridging applications using a combined loan to value ratio across both properties. Your current property serves as security for the bridging loan, while the new property is purchased with a standard mortgage. Most lenders cap total exposure at 80% LVR across both securities when bridging, though some will extend to 90% depending on your income and deposit position.

If your current property is valued at $850,000 with a $400,000 mortgage, and you're buying at auction for $1,100,000, the lender calculates peak debt before your sale settles. You'll be carrying $400,000 on the old property, plus $1,100,000 on the new property, for a total of $1,500,000 secured against combined property values of $1,950,000. That's a 77% LVR, which sits within most lenders' bridging criteria.

Bridging finance costs and interest capitalisation

Bridging loan interest rates sit above standard variable rates, usually between 0.5% and 1.5% higher depending on the lender and your LVR. Interest is capitalised over the bridging period, meaning it compounds and is repaid when the bridge closes. You'll also encounter bridging loan fees, including application fees, valuation costs for both properties, and in some cases a discharge fee when the bridge is repaid.

A six month bridging loan of $1,100,000 at a capitalised rate of 7.5% annually results in roughly $41,000 in interest, which gets added to the loan balance. That figure assumes the bridge runs the full six months. If your property sells in three months, the capitalised interest reduces accordingly. Bridging finance costs are higher than standard lending, but the access they provide to auction properties that would otherwise be out of reach justifies the expense for most buyers upgrading without delay.

Bridging loan approval and timing for auctions

Bridging loan approval requires the same documentation as a standard mortgage application: income verification, asset and liability statements, and valuations for both properties. Lenders also require a clear exit strategy, meaning evidence your current property is listed with a realistic price or already under contract. Fast approval is possible if your documentation is current, but you'll need at least five to seven business days for most lenders to assess and issue formal approval.

If you're planning to bid at auction, lodge your bridging finance application before auction day. Conditional approval allows you to bid with confidence, knowing funds will be available to settle within the contract period. Waiting until after you've signed the contract compresses the timeline unnecessarily and increases the risk that approval doesn't land before settlement.

Bridging loan alternatives and when they apply

Bridging finance isn't the only option for buyers upgrading properties, but it's the most direct when auction timing is non-negotiable. Some buyers use a guarantor arrangement, where a family member provides additional security to increase borrowing capacity temporarily. Others negotiate longer settlement terms on private sales, allowing time for their existing property to sell without needing a bridge. Neither of those options work at auction, where settlement is fixed and contracts exchange on the day.

Equity release is another alternative if you have sufficient equity in your current property to fund a deposit without selling first. That approach works when you're keeping the old property as an investment, but it doesn't address the timing issue faced by upgraders who need to sell before holding two properties long term. Bridging finance remains the most direct solution when auction settlement and sale proceeds don't align.

Bridging loan repayment and closing the bridge

Once your existing property sells and settlement completes, the sale proceeds are used to repay the bridging loan in full. Your lender discharges the bridging loan security, leaving only the mortgage on your new property. If sale proceeds exceed the bridging loan amount, the surplus typically reduces the mortgage on your new home, lowering your ongoing repayments.

Your exit strategy should be confirmed before the bridge is approved. If your property is already under contract, the lender will require a copy of the signed agreement showing the sale price and settlement date. If the property is listed but not yet sold, the lender will review your listing price, recent comparable sales, and agent feedback to assess whether the exit timeline is realistic. Lenders won't approve a bridge without confidence that the exit will occur within the bridging period.

Bridging loan risks and how to manage them

The primary risk with bridging finance is that your existing property doesn't sell within the bridging period. If the bridge term expires before your sale settles, you may need to extend the loan, which incurs additional interest and fees, or refinance both properties into a longer term structure. Pricing your property accurately and working with an agent who understands your timeline reduces that risk significantly.

Another consideration is carrying two mortgages during the bridging period. You're servicing your existing loan while interest capitalises on the bridging loan, which can strain cash flow if the bridge runs longer than expected. If you're concerned about dual repayments, speak to your broker about lenders that allow full capitalisation across both loans during the bridge, meaning no monthly repayments until your sale completes.
