On Sydney's North Shore and Northern Beaches, most of the people we help are not moving into the area — they are moving up within it. That creates a timing problem with no comfortable answer: sell first and you may have nowhere to live, buy first and you are carrying two properties.
Bridging finance exists for exactly that gap. It is well understood and widely available, but it works differently to a standard home loan and it is not the right answer for everyone.
Peak debt and end debt
A bridging loan is usually structured around two figures.
Peak debt is the total you owe while you hold both properties — your existing mortgage, plus the purchase price of the new home, plus costs. It is the high-water mark, and it exists only for the period between the two settlements.
End debt is what remains once the first property sells and the proceeds are applied. That residual becomes your ongoing home loan, and it is the figure the lender is really assessing you against for the long term.
Most lenders will also capitalise the interest during the bridging period, meaning you are not making full repayments on peak debt while you hold both. The interest accrues and is settled when the sale completes.
Closed versus open bridging
Closed bridging applies when your existing property is already under an unconditional contract with a known settlement date. The lender knows when the debt reduces and by roughly how much, so the risk is contained and the terms are generally better.
Open bridging applies when you have not sold yet. The lender is carrying more uncertainty — they do not know when the sale will happen or what it will fetch — so expect a shorter maximum term, a more conservative view of your property's value, and closer scrutiny of your ability to service peak debt if the sale takes longer than planned.
What can go wrong
Bridging is a genuinely useful product, and it does carry risks worth naming plainly.
- The sale takes longer than expected. Bridging periods are finite. Running past the term means renegotiating, usually from a weak position.
- The sale price disappoints. End debt is calculated on what the property actually fetches, not what you hoped. A shortfall becomes ongoing debt.
- Pressure to accept a low offer. This is the real cost of open bridging — the clock can push you into accepting less than the property is worth, which can easily exceed any interest saved.
- Capitalised interest compounds. Not paying interest during the bridging period does not mean not incurring it.
The alternatives worth comparing
Bridging is one option among several, and it is not automatically the best one.
- Releasing equity from your current home before you list, to fund the deposit. Often cleaner than bridging if you have the equity and the serviceability.
- A long or delayed settlement on the purchase, negotiated up front. Costs nothing and solves the timing problem outright when the vendor is amenable.
- A deposit bond or bank guarantee, which covers the deposit without moving cash, though it does not help with the balance at settlement.
- An offer subject to sale, which removes the risk entirely but weakens your position — and is not available at auction.
- Selling first and renting briefly. Unglamorous, and it puts you in the strongest possible buying position with cash in hand.
Who bridging genuinely suits
It tends to work best where there is substantial equity in the existing property, the end debt is comfortably serviceable on its own, the property is in a segment that sells reliably, and there is a real reason the purchase cannot wait — the right home in the right street does not come up often.
It works least well where the numbers only hold together if the sale hits an optimistic price, or where end debt would stretch serviceability even after the sale completes.
Plan it before you start looking
The most common mistake is treating bridging as something to arrange after finding the property. By then you are negotiating under time pressure with no idea of your real ceiling.
Sorted out beforehand, you know your peak debt limit, your end debt position and what the holding period costs — which means you can bid with confidence and walk away when the number stops making sense.
