Bridging finance allows you to buy your next property before selling your current one. It solves a genuine problem: you find the right property but your current home has not yet sold. For Australian property buyers navigating competitive markets in 2026, bridging finance can be the difference between securing your dream home and watching it slip away. Here is how it works, what it costs, and whether it is right for your situation.
How Bridging Finance Works in Australia
You take out a bridging loan that covers both your existing mortgage and the purchase of the new property. This combined amount is called your peak debt. When you sell the existing property, the proceeds pay down the bridging loan and you are left with just the new property loan.
The bridging loan is typically interest-only and has a term of 6 to 12 months. During this period, you are effectively carrying two properties: the one you are selling and the one you have just bought. Most lenders require you to demonstrate strong income to service the peak debt, or they will assess your capacity based on the eventual end debt (the loan remaining after your current property sells).
Bridging finance is not a separate product. It is a temporary loan structure facilitated by your lender, often through a line of credit or redraw facility attached to your main mortgage. The key is timing: you need to sell your existing property within the bridging period, or you face extension fees and potential forced sale scenarios.
Peak Debt Calculation Example
Understanding your peak debt is critical. This is the maximum amount you will owe when you own both properties simultaneously. Here is a worked example for a typical Melbourne family upsizing from a townhouse to a larger family home:
| Item | Amount |
|---|---|
| Existing home value | $1,500,000 |
| Existing mortgage | $500,000 |
| New property purchase price | $1,800,000 |
| Stamp duty and costs | $100,000 |
| Peak debt (total borrowing) | $2,400,000 |
| After sale of existing home (net $1,000,000) | $1,400,000 remaining |
| End debt (new property loan) | $1,400,000 |
In this scenario, the borrower needs to service a $2,400,000 loan for up to six months. At an 8% interest rate, that is $16,000 per month in interest-only repayments. This is manageable for high-income earners, but prohibitive for most buyers without strong cash reserves or rental income from the existing property.
Closed vs Open Bridging Loans
Not all bridging finance is the same. Lenders distinguish between closed and open bridging loans, and the difference affects your interest rate, approval odds, and risk profile.
Closed Bridging Loan
You have exchanged contracts on your existing property sale before the bridging loan starts. This means you have a confirmed settlement date and a known sale price. Lower risk for the lender translates to a lower interest rate, typically 6.5% to 7.5%. Closed bridging is the preferred structure and is easier to approve because the lender knows exactly when the peak debt will be repaid.
Open Bridging Loan
Your existing property has not yet sold, or you have not even listed it. Higher risk for the lender means higher rates, typically 7.5% to 9.5%, and stricter loan-to-value ratio (LVR) requirements. Lenders may cap your LVR at 70% to 80% across both properties to protect against a slow sale or falling prices. Open bridging is harder to approve and much more expensive. If you can, sell first (exchange contracts) before accessing bridging finance.
The Real Cost of Bridging Finance
On a $2,400,000 peak debt at 8% interest-only for six months, the interest bill is approximately $96,000. Add establishment fees ($1,000 to $2,000), valuation fees ($300 to $600 per property), legal fees, and potential extension fees if your sale is delayed. The total cost can easily exceed $100,000.
This is the cost of buying before you sell. Compare this to the cost and uncertainty of renting in between, or losing the property you want because you need to sell first. For many buyers, $100,000 is a reasonable price to pay for certainty and convenience, especially in competitive markets where off-market deals and auction competition can mean missing out on your ideal property.
However, if your existing property is overpriced, in a slow market, or has structural issues that may delay sale, the cost of bridging finance can blow out significantly. Extension fees range from $500 to $2,000 per month, and if you are forced to reduce your asking price under lender pressure, you may lose more in sale price than you save in bridging costs.
Who Bridging Finance Is Right For
Bridging finance is not for everyone. It suits specific buyer profiles and market conditions. Here is who should consider it:
- Upsizers who have found their dream property and do not want to risk losing it. If you are moving from a two-bedroom apartment to a four-bedroom house in the same suburb, and the house is fairly priced and in demand, bridging finance lets you secure it without the stress of a simultaneous settlement.
- Downsizers who need to purchase in an aged care or retirement context. If you are moving into a retirement village or aged care facility and need to buy before selling, bridging finance provides the flexibility to move on your timeline, not the market’s.
- Those in strong-selling markets where they are confident of a quick sale. If you own a well-presented property in a high-demand suburb (think Ivanhoe, Kew, or Brunswick), and comparable properties are selling in under 30 days, bridging finance is low-risk.
- High-income earners with strong cash reserves. If you can comfortably service the peak debt repayments from your salary or rental income, bridging finance is a tactical tool, not a financial strain.
Bridging finance is not suitable for:
- Buyers in slow-moving markets or with overpriced existing properties. If your suburb has high days-on-market and falling clearance rates, do not start a bridging loan.
- Those with limited cash reserves or tight serviceability. If losing your job or a rental vacancy would mean you cannot make repayments, bridging finance is too risky.
- Investors buying off-the-plan or new builds with long settlement periods. Bridging finance is designed for immediate settlement, not 12 to 18 month construction timelines.
Key Risks of Bridging Finance
The primary risk is that your existing property does not sell during the bridging period. If this happens, the lender will typically extend the bridging term with fees, or may require you to reduce the asking price. In worst cases, the lender can require a forced sale, which means accepting a below-market offer to clear the debt.
Other risks include interest rate rises during the bridging period (most bridging loans are variable rate), unexpected repairs or issues with the existing property that delay sale, and market downturns that reduce your sale price below the valuation used to approve the loan.
Never start a bridging loan without a realistic, independently assessed view of your existing property’s selling price and timeframe. Get a professional appraisal, review recent comparable sales, and factor in a buffer. If your agent says your property will sell in 30 days, plan for 60. If they say 60, plan for 90.

Whether you are buying your first investment property, building a portfolio, or simply upsizing your family home, bridging finance is a powerful tool when used correctly. Speak to your mortgage broker, run the numbers, and make sure your existing property is market-ready before you commit.
