If you have lived in Castle Hill, Baulkham Hills or Kellyville for the last decade, you have probably watched your kids outgrow the house. Three bedrooms felt huge in 2014. In 2026, with two teenagers, a home office and a dog, the same house feels half the size. The next move is obvious: a 5-bedroom upgrade nearby. The hard part is the timing. You need to buy before someone else snaps up the home you want, but you also need the equity locked inside your current place to make the numbers work.
This is what bridging finance solves. It lets you settle on the new property while your existing home is still on the market, then collapse the bridging portion once the sale settles. Done well, it removes the renting-in-between drama and the lowball offers that come when buyers know you are under pressure to sell. Done badly, it can leave you carrying $2.6M of debt for six months at 8% interest.
This guide walks you through how bridging finance works in 2026, what the structures actually cost, and how Hills District upgraders can use it without taking on more risk than they need to. Last updated: May 2026.
What a bridging loan is and how it differs from a normal home loan
A bridging loan is short-term finance that funds the gap between buying your new home and selling your old one. Most lenders structure it as a single facility that covers the existing mortgage on your current property, the full purchase price of the new property, and the buying costs (stamp duty, legal fees, lender fees). That total figure is called peak debt. Once you sell your existing home, the net sale proceeds are applied to reduce the loan to what is called end debt, which is the long-term mortgage you keep on the new property.
The differences from a standard home loan come down to three things:
- Term is short. Most lenders cap bridging periods at six months for an existing property already on the market, or twelve months if you are still selling.
- Interest is usually capitalised on the bridging portion, meaning the bank adds the interest to the loan balance rather than asking you for monthly payments while you are also juggling moving costs.
- Serviceability is assessed on end debt only, not peak debt. The bank assumes the sale will happen and looks at whether you can afford the long-term mortgage on the new home.
Bridging finance is most useful when you want to upgrade in the same area, when you have strong equity in your current home, and when local market conditions mean a quick sale is realistic. In the Hills District in 2026, well-presented 3 and 4-bedroom homes in Castle Hill, Baulkham Hills and Kellyville are still moving within 4 to 6 weeks of listing, which makes the strategy workable for most upgraders. For a broader view of how home loans fit together for buyers in your position, see our Sydney home loan options.
When bridging finance makes sense (and when it absolutely does not)
Bridging is the right tool when you have found the right home and the timing of your sale would make you lose it. It is also useful when you want to avoid moving twice, when you have school-aged kids and need to settle into the new home before term starts, or when you want to renovate the new property before moving in. Hills District clients often use bridging when they find a deceased estate or off-market opportunity that needs a fast unconditional offer to win.
It makes sense when:
- Your current home has at least 40% equity, which usually means a loan-to-value ratio under 60% on the existing place.
- Your new purchase price is realistic relative to your end debt capacity (the bank will only approve the bridge if you can service the long-term loan).
- You are confident your existing home will sell within 6 months at a reasonable price.
- You can stomach interest costs of $40,000 to $80,000 over the bridging period without it derailing the upgrade.
- The new property is the one you actually want, not just a fallback.
It does not make sense when:
- You have not yet had your current home appraised by 2 or 3 local agents.
- You are buying in a falling market where your sale price is uncertain.
- Your end debt would push you above 80% LVR on the new property.
- You have less than 6 months of cash reserves to cover delays, repairs, or a price reduction.
- You are buying outside your local area where you cannot read the market.
The two structures: closed bridge vs open bridge
There are two ways banks structure bridging finance, and they price the risk differently.
| Feature | Closed bridge | Open bridge |
|---|---|---|
| Sale status | Contracts exchanged, settlement date known | Not yet sold (may or may not be listed) |
| Typical rate margin | Standard variable plus 0 to 0.20% | Standard variable plus 0.30% to 0.50% |
| Bridging period cap | 30 to 90 days | 6 months (listed) or 12 months (not yet listed) |
| LVR limits | Standard | Tighter (combined LVR usually 75% to 80%) |
| Approval speed | Faster | Slower, more conditions |
Closed bridge. This applies when you have already exchanged contracts on the sale of your existing home with an unconditional contract and a known settlement date. The bank knows when the sale proceeds are landing. Closed bridges are cheaper, usually settle faster, and most major lenders will approve them at standard variable rates plus a small margin.
Open bridge. This applies when you are buying the new home but your existing property is not yet sold, or is on the market but not under contract. The bank is taking on more risk because the sale price and timing are both unknown. Open bridges cost more in interest, have stricter LVR limits, and the lender will assess your serviceability more conservatively. After the bridging period the bank can demand repayment or convert the bridge to a higher-rate temporary loan.
Most Hills District upgraders end up with an open bridge because they find the new property before they have listed the old one. That is not a problem, but it does mean the structure deserves more scrutiny. You want to know exactly what happens at month 6 if the sale has not completed, and you want a written commitment from the bank that the rate will not rise penal if you go over the bridging period by a few weeks. For a deeper view of how pre-approval works before you make an offer, our home loan pre-approval guide walks through the document checklist and timing.
How the bank works out peak debt and end debt
The numbers matter, so let's get specific.
Peak debt is the total amount the bank is exposed to during the bridging period. It is calculated as:
Existing mortgage balance + new purchase price + buying costs (stamp duty, legal, lender fees, moving)
For Sydney upgraders in May 2026, stamp duty on a $2.1M purchase is roughly $98,000, legal and conveyancing runs around $2,500, and lender fees and adjustments add another $2,500. Allow $103,000 in buying costs as a round number, or use a property selling costs calculator to estimate your own. The stamp duty calculator handles the NSW schedule for your specific price point.
End debt is what remains after your existing property sells and the net sale proceeds are applied. It is calculated as:
Peak debt - (sale price - selling costs - existing mortgage payout)
Selling costs in Sydney run 1.8% to 2.5% of the sale price for agent commission, plus marketing, conveyancing, and any pre-sale repairs or styling. For a $1.5M sale, expect roughly $35,000 to $45,000 in selling costs.
The bank will assess two things:
- Whether your end debt is within their normal lending criteria (usually 80% LVR or lower on the new property).
- Whether you can service the end debt on your normal income. They will stress-test the end debt with a 3% rate buffer, which in 2026 means assessing your ability to service the loan at around 9.5% to 10.5%.
If you want to sanity-check your end debt position before you start, run the numbers through our borrowing power calculator using just the end debt figure, not peak debt.
A worked example: $1.5M Castle Hill sale, $2.1M Kellyville purchase
Let's put real numbers on a typical Hills District upgrade. A couple in their late 40s own a 3-bedroom home on a 600m2 block in Castle Hill, worth $1.5M. They have $400,000 left on their existing mortgage. They have found a 5-bedroom family home in Kellyville for $2.1M, on a 750m2 block with a pool. They want to settle on Kellyville first, move in, then list Castle Hill for sale.
Peak debt calculation:
| Component | Amount |
|---|---|
| Existing mortgage on Castle Hill | $400,000 |
| Purchase price of Kellyville | $2,100,000 |
| Stamp duty (NSW, May 2026 schedule) | $98,488 |
| Legal, conveyancing, lender fees, moving | $4,500 |
| Peak debt total | $2,602,988 |
The bank assesses this as an open bridge, since Castle Hill is not yet listed. The couple's combined income is $320,000, and on the bank's serviceability calculation they can comfortably service an end debt of $1.2M at the stress-tested rate. The bridging interest rate is 8.25% per annum (a 0.30% margin above the lender's standard variable rate of 7.95% for an open bridge in May 2026).
Bridging period assumption: 6 months.
Interest on the bridging portion (the $2.2M of new debt) capitalises monthly. At 8.25%, the bridging interest is roughly:
$2,200,000 x 8.25% x 6/12 = $90,750
The existing $400,000 mortgage continues on its current rate (let's say 6.4% on a fixed loan), accruing $12,800 over the 6 months. Most banks roll this into the bridging facility too, so it effectively capitalises.
Total interest cost over the bridging period: approximately $103,550.
In practice, our Hills District clients sell faster than 6 months. If Castle Hill sells within 3 months, the bridging interest drops to roughly $52,000. If it sells in 4 months, around $69,000. The 6-month assumption is a planning ceiling, not the realistic number.
End debt calculation:
- Castle Hill sells for $1.5M (assume the listed price is achieved)
- Selling costs: $40,000 (2.0% agent commission, marketing, conveyancing)
- Net sale proceeds: $1,460,000
- Payout of existing $400k mortgage: $400,000
- Available to apply against peak debt: $1,060,000
- End debt: $2,602,988 - $1,060,000 = approximately $1,543,000
Plus the capitalised bridging interest of around $70,000 (assuming a 4-month bridge), the long-term mortgage settles at roughly $1,613,000 on the Kellyville property. With Kellyville valued at $2.1M, the end LVR is 77%, which is within standard lending criteria.
This is the kind of upgrade that bridging is built for. The couple gets to settle on Kellyville without a contingent offer, moves in over the school holidays, presents Castle Hill empty and well-styled (commanding a stronger price), and pays around $70,000 in total bridging cost for the privilege. Compared to losing the Kellyville property entirely and paying $250,000 more for an equivalent home twelve months later, the math is straightforward.
Bridging interest rates in 2026 (what to actually expect)
The RBA cash rate sits at 4.35% after the 5 May 2026 hike. Here is what the main lenders are pricing in May 2026:
| Lender | Closed bridge | Open bridge |
|---|---|---|
| CBA | 7.95% to 8.25% | 8.25% to 8.55% |
| Westpac | 8.10% to 8.40% | 8.40% to 8.85% |
| NAB | 8.00% to 8.30% | 8.30% to 8.50% |
| St George / BankSA | 7.95% to 8.20% | 8.20% to 8.40% |
| Macquarie | 7.85% to 8.05% | 8.05% to 8.25% |
Your actual rate will depend on loan size, LVR at peak and end debt, and the lender's view of your serviceability. A broker running the deal across 4 or 5 lenders will typically save you 0.20% to 0.40%, which on a $2.2M bridge over 6 months is $2,200 to $4,400 of real money. Smaller lenders and non-banks offer bridging from 9.5% to 12% for clients who do not fit major bank criteria.
How to qualify: serviceability and equity rules
The qualification rules for bridging finance in 2026 are stricter than they were 3 years ago, mostly because lenders have tightened across the board after the 2023 to 2025 rate cycle. Here is what the banks look for:
- Equity in your existing property. Most lenders want at least 40% equity in your current home (so a 60% LVR or lower on the existing mortgage). For a Castle Hill home worth $1.5M with $400k owing, your equity is $1.1M (73%), which comfortably meets the test.
- End debt LVR under 80%. The bank will not approve a bridge if the long-term loan would put you above 80% LVR on the new property.
- Serviceability on end debt with a 3% rate buffer. Income is stress-tested against the end debt at the bridging rate plus 3%, which in 2026 means assessing repayment capacity at around 11.25%.
- Property type. Standard residential properties are easiest. Large rural blocks, unusual zoning, or development-corridor properties may attract lower valuations or outright decline.
- A signed sales agency agreement. CBA and Westpac will often accept a verbal commitment to list. NAB and Macquarie prefer a signed agreement.
The risks and how to manage them
Bridging finance is a powerful tool but it does carry real risks. The honest list:
- Sale takes longer than expected. If your Castle Hill home takes 9 months to sell instead of 4, you carry an extra 5 months of interest. At $2.2M bridging at 8.25%, that is another $75,000 of capitalised cost. Mitigation: build a 6-month bridging period into your planning. List early. Use a top local agent. Price realistically.
- Sale price comes in below expectation. If you list at $1.5M and sell at $1.4M, your end debt goes up by $100k. Mitigation: get 2 to 3 independent agent appraisals before you commit. Build a 5% to 10% buffer into your numbers.
- Interest rate rises during the bridging period. Bridging rates are variable. If the RBA hikes by 0.25% during your 6-month bridge, your capitalised interest rises proportionally. Mitigation: most banks will let you fix the bridging rate for the duration of the bridge if you ask.
- You change your mind on the new property after settlement. If you settle and then realise the property has problems, you are committed. Mitigation: do a thorough pre-purchase inspection. Visit at different times of day. Talk to the neighbours.
- End debt is approved on assumptions that change. If you lose your job during the bridging period, you may struggle to service the end debt. Mitigation: stress-test the deal at 50% to 70% of your current income.
Alternatives to bridging finance
Bridging is not the only way to upgrade. Depending on your situation, one of these alternatives may suit better:
- Sell first, then buy. You list your home, sell it, then have 4 to 8 weeks to find and settle a new one. Cheaper because you avoid bridging interest, but you risk losing the new home while you sell, and you may need to rent in between.
- Long settlement on the purchase. Negotiate a 90 or 120-day settlement on the new home, giving you time to sell in parallel. Costs nothing extra unless the vendor demands a higher price for the longer wait.
- Deposit bond. A deposit bond replaces the 10% cash deposit at exchange with an insurance-backed guarantee. It lets you exchange contracts without tying up cash.
- Simultaneous settlement. Both contracts settle on the same day. Sale proceeds flow directly into the purchase. Works when timing aligns perfectly, but one delay can collapse the chain.
- Rent-back arrangement. You sell your home but negotiate to rent it from the buyer for 30 to 90 days after settlement.
- Equity release on existing home. Keep your existing home as an investment and release equity to fund the deposit on the new home, carrying two mortgages permanently. The math only works if rental yields and your serviceability support both.

Step-by-step process from application to settlement
Here is what the bridging finance process actually looks like, week by week, for a typical Hills District upgrade:
- Weeks 1 to 2: Strategy and pre-approval. Talk to a broker. Get clear on your peak debt, end debt, and serviceability. Run the numbers against 3 or 4 lenders. Get formal pre-approval with bridging conditional approval attached. Get 2 to 3 agent appraisals on your existing home.
- Weeks 3 to 6: Find and exchange on the new property. With pre-approval in hand, you can move quickly. Exchange contracts subject to finance (or unconditional if you have full approval). The bank issues formal approval conditional on satisfactory valuations.
- Weeks 6 to 10: Settlement on the new property. The bank settles using the bridging facility. Peak debt is now in place. You move in. Your existing home is listed within 7 to 14 days of new settlement.
- Weeks 10 to 24: Sale of existing home. Your existing home is on the market. Bridging interest is capitalising. You continue to make repayments on your existing mortgage if it is kept separate.
- Weeks 18 to 30: Settlement on the sale. Once contracts exchange, settlement is usually 42 days later in NSW. Sale proceeds flow to the bank, which applies them against peak debt and converts the bridging facility into a standard mortgage on the new property.
- Week 30 onwards: Normal home loan. You are on a standard variable or fixed-rate home loan, with monthly principal-and-interest repayments. The bridge is collapsed and behind you.

Quick answers
Frequently asked questions
A bridging loan is short-term home finance that lets you settle on a new property before selling your existing one. The lender provides a single facility covering your existing mortgage, the full purchase price of the new home, and the buying costs. That total is called peak debt. Interest is usually capitalised on the bridging portion, so you do not make monthly repayments on it during the bridging period. Once your existing home sells, the net proceeds reduce the loan to a long-term mortgage on the new property, called end debt. The bridging period is typically capped at 6 months for properties already on the market or 12 months for properties not yet listed.
Most lenders allow 6 months on an open bridge if your home is already listed for sale, or 12 months if it is not yet listed. Closed bridges (where you have already exchanged contracts on the sale) are typically capped at 90 days. If you go past the bridging period without selling, the bank can demand repayment, refuse to extend, or convert the loan to a higher-rate temporary facility. In practice most well-presented Hills District homes sell within 4 to 8 weeks of listing, so the 6-month cap is rarely a real constraint, but you should plan for the worst case.
In May 2026, bridging rates range from 7.85% to 8.85% with the major lenders, depending on the structure. Closed bridges price at the lower end, open bridges at the higher end. Smaller and non-bank lenders charge 9.5% to 12% for borrowers who do not fit major-bank criteria. Rates are variable and reflect the RBA cash rate of 4.35% set on 5 May 2026. A broker who runs the deal across multiple lenders will usually save you 0.20% to 0.40%, which on a $2M bridge over 6 months is real money. You can often request a fixed bridging rate for the duration of the bridge.
Yes. This is called an open bridge. Most major lenders will approve it provided you commit to listing the property within 30 to 60 days of new settlement, you have at least 40% equity in your existing home, and you can service the end debt comfortably. Some lenders (NAB, Macquarie) prefer a signed agency agreement before approval. Others (CBA, Westpac) will accept a verbal commitment. Open bridges cost 0.25% to 0.50% more than closed bridges in interest, and the bridging period is usually capped at 6 to 12 months. Most Hills District upgraders use this structure.
A closed bridge applies when you have already exchanged contracts on the sale of your existing home with an unconditional contract and a known settlement date. The bank knows exactly when sale proceeds will arrive, so the structure is cheaper, faster to approve, and the bridging period is short (30 to 90 days). An open bridge applies when you are buying first and selling later, with no signed sale contract in place. It is more flexible but more expensive, with stricter equity and LVR requirements. Most upgraders in the Hills District use open bridges because they find the new property before listing the old one.
On most major bank bridging structures, interest is capitalised on the bridging portion, which means the bank adds the interest to the loan balance each month rather than asking you for monthly repayments. You still make repayments on your existing mortgage (if it is kept separate) or on the long-term portion of the new loan. Capitalisation makes cash flow easier during the bridging period, which is important because you are also paying moving costs, possibly renovating, and managing two properties. The interest accrues against your end debt, so you do effectively pay it once the sale settles.
The maximum is determined by two limits. First, your end debt must be within the bank's serviceability rules (usually 80% LVR or lower on the new property, and your income must service the long-term loan at a stress-tested rate). Second, your peak debt must be within the bank's bridging policy, which usually caps the combined LVR across both properties at 75% to 80%. For most Hills District upgraders with strong existing equity, the binding constraint is end-debt serviceability, not peak debt. In practice we see bridges from $800,000 up to $4M, with $1.5M to $2.5M being the common range.
If you reach the end of the bridging period without selling, the bank has three options. They can extend the bridge for a further 3 to 6 months, usually with conditions (a price reduction, a different agent, evidence of marketing activity). They can convert the bridge to a higher-rate temporary loan, often at the standard variable rate plus 1% to 2%. Or in extreme cases they can demand repayment, which would force a quick sale at whatever price you can get. The mitigation is to price your existing home realistically from day one, use a strong local agent, and start the listing process as soon as the new property settles.
No. The major lenders (CBA, Westpac, NAB, ANZ) all offer bridging, as do most second-tier banks (St George, BankSA, Bank of Melbourne, Bankwest, ING, Suncorp) and the larger non-banks (Macquarie, ME Bank, Pepper). Some smaller lenders and credit unions either do not offer bridging, or only offer closed bridges with strict conditions. A broker can run the deal across 5 to 6 lenders quickly to find the best rate and structure for your situation. Pricing and policy vary meaningfully between lenders, so it pays to shop the deal.
They solve different problems. A deposit bond covers only the 10% deposit at exchange, so you can lock in a contract without tying up cash. It does not help you settle the full purchase price. A bridging loan covers the entire purchase price (and your existing mortgage), so you can settle on the new property before selling. If your existing home will sell quickly and you can settle simultaneously or close to it, a deposit bond plus a long settlement may be enough. If you want to actually move into the new home before selling, you need a bridge. For Hills District upgraders who want to physically settle before listing the old home, bridging is the right tool.
