Bridging Finance Explained: How to Buy Before You Sell

The Problem Bridging Finance Solves
In an ideal world, every property transaction would involve perfect timing: you sell your existing home on one day and settle on your new purchase the next. In practice, settlement dates rarely align this cleanly. Sellers may need time to find their next home, buyers' conditions take time to clear, and the property market does not wait for convenient scheduling.
Without bridging finance, the conventional approach is to sell first and then buy, which means either needing to negotiate a lengthy settlement on your sale, or accepting a period of renting or living with family while you search for a new property. For many buyers, particularly those in competitive markets, having to sell unconditionally before buying puts them at a significant disadvantage.
Bridging finance removes this constraint. The lender effectively funds the purchase of the new property while your existing home remains on the market, with the full debt position resolved once the sale settles.
How the Loan Is Structured
The mechanics of bridging finance vary between lenders, but the most common structure works as follows. When you apply for a bridging loan, the lender calculates your peak debt: the combined value of your existing mortgage (if any) and the loan required to purchase the new property. During the bridging period, typically up to six or twelve months, you hold both properties and make interest payments, often capitalised (added to the loan balance) rather than paid out of pocket each month.
Once your existing property sells, the net proceeds from that sale are applied to reduce the total debt. The remaining balance becomes your ongoing loan on the new property, ideally structured as a standard principal and interest loan at that point. If the sale proceeds are sufficient, the bridging arrangement concludes cleanly. If the sale price is lower than expected, you may carry a higher ongoing loan balance than planned.
Closed vs Open Bridging
Bridging loans are categorised as either closed or open, depending on whether the sale of the existing property has already been contracted.
A closed bridge means contracts have been exchanged on the sale of your existing property. The sale is legally committed, and only settlement is pending. Lenders are considerably more comfortable with this scenario because the sale proceeds are known and the repayment of the bridging debt is largely certain. Closed bridging typically attracts lower rates and more straightforward approval conditions.
An open bridge means your existing property has not yet been sold. The lender is lending against an assumed future sale price, which introduces uncertainty. Open bridging is more expensive to service, comes with stricter lending criteria, and typically carries a maximum term. Most lenders will not extend open bridging beyond six to twelve months. If your property has not sold within the bridging term, you may face pressure to reduce the asking price or explore other refinancing options.
The Costs to Understand
Bridging finance is more expensive than standard home loan finance for several reasons. Interest rates on bridging products tend to sit higher than equivalent standard variable rates. The peak debt figure (which can be substantially larger than your eventual end debt) accrues interest throughout the bridging period. When interest is capitalised rather than paid, the compounding effect can materially increase the total cost.
There are also establishment fees, potential valuation fees on both properties, and legal costs associated with the bridging structure. Lenders may require building and pest inspections on the new purchase and a formal valuation of your existing property to determine their comfort with the assumed sale price.
| Feature | Closed Bridge | Open Bridge |
|---|---|---|
| Sale contracted? | Yes. Exchange completed. | No. Property not yet sold. |
| Lender comfort | Higher | Lower |
| Interest rate | Generally lower | Generally higher |
| Typical maximum term | Up to 12 months | 6–12 months (strictly enforced) |
| Risk to borrower | Lower (sale outcome known) | Higher (sale price uncertain) |
When Bridging Finance Makes Sense
Bridging finance works best when the borrower has strong equity in their existing property, a realistic sale price that comfortably covers the anticipated shortfall, and a clear timeline for settlement. It is most suitable in markets where properties are selling within normal timeframes, not those where extended days on market are common, as a prolonged bridging period amplifies costs significantly.
It is less suitable when the existing property's value is uncertain, when the borrower has limited income relative to the peak debt obligations, or when the sale timeline is highly unpredictable. In those cases, the risk of carrying two properties at elevated interest costs, potentially for longer than expected, can put significant financial pressure on the borrower.
A broker can model the worst-case outcome: what happens if your existing property takes four months longer to sell than expected, or sells for $50,000 less than anticipated, and help you determine whether the bridging structure remains viable under those conditions before you commit.
Key Takeaways
- Bridging finance covers the financial gap between purchasing a new property and settling the sale of your existing one.
- The peak debt during bridging includes your existing mortgage plus the new purchase loan. Interest accrues on the full combined amount.
- Closed bridges (existing property already contracted for sale) are lower risk and generally cheaper than open bridges.
- Open bridging carries meaningful risk: if your property takes longer than expected to sell, costs escalate and the lender may enforce a sale.
- Bridging works best with strong existing equity, a realistic sale price estimate, and a short, predictable gap between settlement dates.
- Always model the downside scenario before proceeding: what the position looks like if the sale takes longer or achieves less than expected.
