Bridging Loans in Australia: Verify the Debt, Cost and Exit Plan
A practical, source-led guide to bridging finance, peak and end debt, lender-specific terms, sale assumptions and the questions to answer before buying first.
Short-term finance covering the period between buying a new property and selling an existing property. The exact debt structure, term, repayments, security and sale requirements are set by the lender's product and loan contract.
Bridging finance can fund a purchase before the sale proceeds from an existing home are available. That simple purpose hides several moving parts: two properties, sale-price assumptions, a short contractual term and a larger temporary debt. The decision should be made from a written lender proposal and realistic sale evidence, not from a headline rate or an expected best-case sale price.
What bridging finance does
ASIC's Moneysmart defines bridging financeas short-term finance covering the period between buying a new property and selling an existing one. Beyond that definition, products differ. For example, ANZ's current public material describes its own bridging product as combining the current and new home lending, with interest-only repayments during a stated maximum period. Westpac describes assessment of “peak debt” and warns that interest may be capitalised under its product. Those are lender-specific terms, not rules for every bridge.
Do not copy another lender's terms
A term, rate, loan-to-value limit or repayment method shown on one lender's page applies only to that lender's stated product and is subject to approval and change. Confirm every material term in the proposal for the facility actually being considered.
Peak debt and end debt
Lenders may use different labels and calculations, but two figures are central to a bridge:
- Temporary or peak debt:the highest projected amount owed while both properties are held, after allowing for the borrower's cash contribution and any costs or interest included in the facility.
- End debt: the amount expected to remain after the existing property settles and its net sale proceeds are applied as required by the loan contract.
Westpac's current bridging explanationsays its application is assessed on peak debt and identifies valuation costs, interest on interest and a short term as potential downsides. Ask the proposed lender for its own calculation, including each input. Do not reconstruct it from a different bank's example.
The expected end debt is only as sound as the assumed sale proceeds. Start with expected sale price, then deduct the existing mortgage payout, selling commission, marketing, legal and settlement costs, and any other amount that will not be available to reduce the bridge.
How to calculate the real cost
There is no reliable national “typical” bridging rate or fee. Pricing changes and may depend on the property, loan-to-value ratio, borrower and product. ASIC's home-loan comparison guide says to compare the interest rate, comparison rate, repayments, application and ongoing fees, term and features. For a bridge, add the temporary debt profile and sale timing.
- Obtain a dated written quote showing the rate, comparison rate and every fee.
- Confirm the balance on which interest will be calculated each day.
- Confirm whether interest is paid, capitalised, or handled differently across loan splits.
- Model several settlement dates using the quoted rate, not a market average.
- Add selling, valuation, legal, discharge and purchase costs from actual quotes or official calculators.
- Recalculate the end debt using lower net sale proceeds.
If repayments are interest-only during any period, ASIC's interest-only guidance explains that principal is not reduced by those scheduled payments and that later principal-and-interest repayments may be higher. Check the exact transition in the loan contract.
What the lender may assess
A lender may assess income, expenses, existing liabilities, credit history, both properties, available equity, the proposed sale and the debt remaining afterwards. The inputs and approval decision remain lender-specific.
APRA states that APRA-regulated banks must apply a minimum mortgage serviceability buffer of three percentage points above the loan rate when assessing a new borrower's capacity. Its May 2026 System Risk Outlook also explains that this is a minimum system setting. It is not the interest rate charged, a borrowing recommendation, or a promise that a lender will approve a particular bridge.
A lender may also require valuations or impose a maximum loan-to-value ratio. If lenders mortgage insurance is relevant, confirm the premium and whether it is added to the debt; see our LMI guide. Product availability does not show that bridging is suitable for the borrower.
Stress-test the sale assumptions
Replace confidence about the sale with three documented scenarios. For each, calculate the net sale proceeds, time carrying the temporary debt, interest using the proposed lender's terms, and resulting end debt.
- Evidence case: the price and campaign length supported by comparable settled sales and agent evidence.
- Lower-proceeds case: a lower price plus the full selling costs.
- Delayed-settlement case: a later sale or settlement within the contractual bridge period.
Also ask what happens if the property remains unsold when the term ends. There is no universal outcome. Extension, repricing, refinance, enforcement and sale provisions depend on the contract and lender decision. Contact the lender before a deadline is missed and obtain independent advice if the exit plan is no longer credible.
Questions to answer in writing
Bridge proposal checklist
- What is the lender's calculated peak debt, and what inputs does it include?
- What sale value and selling-cost allowance has the lender used?
- What end debt is projected, and how was serviceability assessed?
- What is the maximum bridge period, and when does it begin and end?
- Which rate applies to each loan split, and can that rate change?
- Is interest paid or capitalised, and can interest be charged on capitalised interest?
- What application, valuation, package, discharge and extension-related costs can apply?
- What repayments are required while both properties are held?
- What security does the lender take over each property?
- What does the contract allow the lender to do if the sale is late or proceeds are insufficient?
- Can extra repayments be made, and can they later be redrawn?
- Which conditions must be satisfied before funds are available for settlement?
Alternatives to compare
- Sell before buying: establishes the net proceeds before committing to the next purchase, but may require temporary housing or another move.
- Coordinate settlements: ask the conveyancer whether contract dates can align. This depends on both transactions and the other parties.
- Longer settlement or a sale condition: only if the seller agrees and the conveyancer confirms the wording and consequences.
- Deposit bond: may address the contract deposit rather than the full purchase funding gap. The seller must accept it and the buyer still needs settlement funds. Read the deposit-bond guide.
A bridge is a short-term debt arrangement, not a forecast that the existing home will sell on time or at the expected price. The defensible decision uses the actual lender terms, net sale evidence and a lower-price, later-settlement stress test.
