Bridging Loans Australia: How Bridging Finance Works (2026)

Bridging Loans in Australia: What They Are and How They Work

By Patrick O’Brien, Director and Home Loan Specialist, Mortgage World Australia (since 2001)

A bridging loan is a short-term home loan that lets you buy your next home before you’ve sold the one you live in. The lender rolls your existing mortgage and the money for the new purchase into one combined balance, called the peak debt, and gives you a set period, up to twelve months at the lenders on our panel that write bridging, to sell. When your old home sells, the sale proceeds pay that balance down to the end debt, which carries on as an ordinary home loan on your new property.

That’s the mechanism. Whether it works for you comes down to three numbers: what you’ll owe at the peak, what you’ll owe once the sale settles, and how long the gap lasts.

Bridging finance is built for people moving house: upgraders, downsizers and families who have found the right place before their current home is on the market. First home buyers don’t use it, because there’s nothing to sell. It is also narrower in practice than comparison sites suggest. Only some lenders on our panel write bridging loans, their rules differ widely on term, interest and servicing, and a comparison tool will list more bridging lenders than will actually write your loan.

Below is a worked example in dollars, then open and closed bridging, interest, what lenders assess, costs and risks. We finish with the alternatives we often suggest first.

What is a bridging loan?

A bridging loan (also called bridging finance, a relocation loan, or a swing loan in the United States) covers the timing gap between buying and selling. Without it, you either sell first and risk renting between homes, or you try to line up two settlements on the same day.

With it, you settle on the new home using borrowed funds secured against both properties, move in, then sell the old home on your own timeline. The lender holds a mortgage over both homes until the sale settles.

One point surprises a lot of people. A bridging loan lets you buy before you sell. It does not let you keep the old place. A client once asked us to bridge her into the next home while she held her current one as an investment. Bridging could fund the gap, but only on the basis that the outgoing home would be sold, so the “keep it” version of the plan was never on the table. If you want to hold both, that is an equity release or a second property loan, which we cover in our guide to buying a second home with equity.

How does a bridging loan work?

Most bridging loans follow the same five steps:

1. Assess. Before you bid or sign, the lender values your current home and assesses the new purchase, your income and your expected end debt.
2. Settle on the new home. The lender advances the purchase price and costs. Your existing loan stays in place, so you now owe the peak debt.
3. Hold both properties. This is the bridging period. Interest accrues on the peak debt, either paid monthly or added to the balance, depending on the lender.
4. Sell the old home. Once the sale settles, the net proceeds (after agent fees, marketing and legal costs) go straight to the lender.
5. Carry on with the end debt. What’s left is your ongoing home loan, with normal principal and interest repayments.

It is usually set up as two loan accounts: a bridging account that is paid off and closed when the sale settles, and an end-debt account that stays. If you are downsizing and the sale covers everything, there may be no end debt at all.

Peak debt and end debt: a worked example

Peak debt is the most you’ll owe at any point: your existing mortgage plus everything you borrow for the new home, including purchase costs. End debt is what remains after the net sale proceeds are applied.

Here is a Sydney upgrade in dollars, with no cash contribution. The buyer is not a first home buyer, so standard NSW transfer duty applies to the new home.

The duty figure is $52,237 plus $5.50 for every $100 over $1,290,000, from the Revenue NSW transfer duty rates. Transfer duty figures are based on rates effective 1 July 2026, sourced from Revenue NSW. Other states use different rates, so swap in your own figure.

Two things change this picture in real life.

Capitalised interest. If the lender adds interest to the balance instead of taking monthly payments, the peak debt grows every month. Suppose the interest added over the bridging period comes to $60,000 (the real figure depends on the rate and how long the sale takes). Peak debt rises to $2,028,787, or 78.0% of the combined security, and the end debt becomes $956,287. That extra interest has to fit inside the lender’s limit on peak debt as well: where interest is capitalised, the estimated interest counts inside that limit.

A lower sale price. If the old home sells for $1,000,000 instead of $1,100,000, selling costs fall to $25,000, net proceeds drop to $975,000 and the end debt rises to $993,787. That is $97,500 more debt to carry for the next 25 or 30 years, and it is the number to stress-test before you sign anything. You can check your own figures on our LVR calculator.

In our experience, most “how much can I borrow” questions from upgraders are really “how much will my house sell for” questions in disguise. Before we model a bridging loan, we usually start by asking for three agent appraisals on the current home.

Open vs closed bridging loans

The distinction is whether your current home has already sold.

A closed bridge needs an exchanged, unconditional contract at every lender, and it is the easier approval because the lender can see exactly when and how the loan gets repaid. An open bridge carries the market risk. For an open bridge, a few lenders on our panel take around 10% to 20% off the valuation of the home you’re selling. Some want a signed agency agreement, and several insist on holding security over the home you’re selling so they control the sale proceeds. Open and closed are industry terms rather than product names.

How long does a bridging loan last?

Lenders on our panel that write bridging give you up to twelve months to sell, whether or not the old home has sold. A few limit open bridging to six months where no contract has been exchanged. Extensions are sometimes considered, but you can’t count on one.

A common question is whether a longer settlement on the purchase removes the need for bridging. Usually it doesn’t. We had a buyer ask whether pushing a 42-day settlement out to 60 days would save him. Eighteen extra days didn’t change whether his existing home had sold, so he needed bridging either way. Only something like a three-month settlement changes that, and a vendor sitting on an empty house rarely agrees to that.

How is interest handled: capitalised or paid monthly?

During the bridging period you pay interest, not principal. On a peak debt near $2 million, that is a large monthly bill. Lenders deal with it in one of two ways.

• Interest paid monthly. You make interest-only repayments on the peak debt every month. Total interest is lower, because you’re not paying interest on interest, but you need the cash flow to cover it while you’re also preparing and marketing the old home.
• Interest capitalised. Nothing is paid on the bridging portion during the term. Interest is added to the balance and cleared from the sale proceeds. Cash flow is easier, but the balance grows, so the total cost is higher and your end debt can be larger if the sale drags.

Around half the lenders on our panel that write bridging will capitalise the interest for up to twelve months, and most of those add an estimate of that interest to the peak debt before testing the LVR. The rest want interest paid monthly, and at a couple the capitalisation runs for a limited period before interest-only repayments start. That one policy setting often decides which lender can approve the loan, more than the interest rate does. Moneysmart’s guide to interest-only loans explains why interest-only payments leave the balance where it is.

What lenders assess for a bridging loan

A bridging application is a normal home loan application with three extra questions attached.

Can you service the debt? Most lenders on our panel test your income against the end debt, the loan left after the sale clears the bridging portion. A few test it against the full peak debt, as if you’ll hold both loans indefinitely. The ones that capitalise interest tend to test the end debt, which is why they suit single-income upgraders.

Is there enough equity across both properties? Lenders measure the peak debt against the combined value of both homes. Most lenders on our panel cap peak debt at 80% of that combined value; one or two will go to 85% with mortgage insurance. Where interest is capitalised, the estimated interest counts inside that limit. Bridging doesn’t solve a peak-debt problem; it just relocates it. A buyer looking at a $2 million property asked us about bridging, and the answer was no, because peak debt would still have been over 80%. She ended up selling first.

How certain is the sale? For a closed bridge, every lender wants an exchanged, unconditional sale contract. For an open bridge, a few lenders on our panel take around 10% to 20% off the valuation of the home you’re selling, which pushes up the end debt they assume, and several insist on holding security over that home so they control the sale proceeds.

Three practical points from recent files:

• Fewer lenders than it looks. A panel comparison tool lists more bridging lenders than will write a given loan in practice. At least one lender only considers bridging for existing customers whose current loan is more than two years old, even though a comparison tool lists it as an option. We confirm bridging appetite with the lender directly before a client relies on it.
• Extra paperwork at some banks. One major bank asks you to sign an undertaking to meet the market (a commitment to sell the property at a realistic price), and on one file its assessor insisted on a wet signature rather than a digital one. We build that into the signing plan early.
• Self-employed options exist. At least one specialist lender offers near-prime bridging to 80% LVR for self-employed borrowers using alternative income documentation.

Bridging loan costs

Bridging loans cost more than a standard home loan, mostly because you pay interest on a very large balance for months. The main costs are:

• Interest on the peak debt for the whole bridging period. The rate on the bridging portion varies by lender, but the bigger driver is time: every extra month the old home takes to sell adds another month of interest on the full balance.
• Two valuations, one on each property.
• Loan fees: application, settlement and discharge fees on the bridging account.
• Purchase costs on the new home, mainly transfer duty (see the worked example).
• Selling costs on the old home: agent commission, marketing and conveyancing.

We don’t quote bridging rates here because they move and differ sharply between lenders. What we model for a client is the total cost across a realistic sale timeline, say four, eight and twelve months, because the lowest rate on paper is not always the lowest total cost once the timeline stretches.

Interest on the part of a loan used to buy your own home isn’t tax-deductible. If part of the borrowing funds an income-producing property, the ATO’s rules on interest expenses apply to that part, and mixed-purpose loans need to be apportioned. Get tax advice on your own situation.

The risks: what if your home doesn’t sell?

The whole structure rests on one sale. These are the three ways it goes wrong.

1. It takes longer to sell. Every month adds interest on the full peak debt, and if interest is being capitalised the balance keeps growing.
2. It sells for less. A lower price flows straight into a higher end debt, as the $97,500 swing in the worked example shows. That end debt then has to be serviced for decades.
3. It doesn’t sell within the term. The lender can apply a higher rate, require you to reduce the balance or take steps to sell the property, and any shortfall is added to your ongoing loan.

A valuation shortfall is a related trap. If the lender’s valuer puts your current home well below what you expected, the loan may not be approved at the size you need. On one file we told the client plainly that below about $1.4 million there would be a shortfall to find. A low valuation can sometimes be tested by ordering through a different lender, which usually means a different valuer.

You can cut the risk down. Price the old home realistically from day one and list it before, or as soon as, you buy. If you’re paying interest monthly, keep a cash buffer for it. And model the end debt at a sale price 10% below the appraisal, not at the agent’s top figure.

Bridging for building, renovating or flipping

The search term “bridging loan” covers several different products, and only one of them is a home-moving bridge.

Building your next home. Some borrowers want to stay in their current home while a new one is built, then sell. Around half a dozen lenders on our panel will bridge a build, with the sale period running up to twelve months and the construction cost sitting inside the end debt. The bridging clock generally starts at the beginning, not at construction completion, and one major bank does not allow construction inside a bridging loan at all. Our construction loan guide covers how construction draws work.

Renovating or flipping a property. One or two lenders on our panel will bridge into an investment purchase, and at a few the property being sold can be an investment even where the new one must be your home. Most write bridging for owner-occupiers only, and investors doing a flip usually look at short-term private or business lending instead. At least one short-term business lender offers terms of one to six months (extendable) and lends up to 80% of a residential property’s value. Interest is capitalised for the first six months.

Property development. In development finance, “bridging” means short-term funding for a site while longer-term project finance is arranged. That is commercial lending, assessed on the project rather than your household income, and it is a separate conversation.

Alternatives to a bridging loan

Bridging is what you use when you can’t control the order of events. It isn’t the default, and we often find a lower-cost route first.

• Sell first. You know exactly what you have to spend and carry one loan. The cost is the risk of renting or moving twice if you don’t find the next place in time.
• Control the order of the signatures. A client trading up in a fast market agreed the sale price on his existing home first, then signed the purchase about 24 hours later. That one day meant the sale was effectively locked before the purchase commitment existed, which removed the bridging exposure at no cost.
• Buy subject to sale. Your purchase is conditional on selling your current home. It’s the safest option for you and the weakest offer for the vendor, so it works better in a slower market or a private sale than at auction.
• Use a deposit bond. If the problem is only the deposit on exchange, not the full purchase price, a deposit bond can stand in for the cash deposit until settlement. On one purchase we had the client pay the initial holding deposit from savings and arrange a deposit bond at the end of the cooling-off period.
• Release equity from your current home. If your equity and income are strong enough, a loan increase or a separate equity loan can fund the deposit and costs, with the new home carrying its own loan. You need to be able to service both loans, so this only works if the numbers stack up.

Who a bridging loan suits

A bridging loan tends to suit you if:

• You’re upgrading or downsizing and have found the next home before selling.
• You have substantial equity in your current home, enough to keep peak debt within the lender’s limit.
• Your home is in a market where comparable homes sell reliably and you can price it realistically.
• You can either service interest during the bridge or qualify with a lender that capitalises it.

It usually doesn’t suit you if your equity is thin, your home is unusual or slow to sell, you want to keep the old property, or the plan only works at the top of the agent’s price range.

The bridging loan process and timeline

1. Talk to us before you bid. We model peak debt, end debt and total cost across a few sale timelines, and check which lenders on the panel will actually write your scenario.
2. Get appraisals and a valuation. Agent appraisals on your current home, then a lender valuation.
3. Pre-approval. Where the lender offers it, get bridging pre-approval before auction or exchange.
4. Formal approval and settlement on the new home. Valuation of the new property, loan documents signed (including any undertaking the lender requires) and settlement. Our home loan approval and settlement timeline walks through each stage.
5. Sell and settle the old home within the bridging term. The net proceeds go to the lender and the bridging account closes.
6. Review the end debt. Once the sale has settled, check that the ongoing loan still fits, including rate, offset and repayment type.

The approval itself runs on a normal home loan timeline. The sale is what decides the outcome, which is why the modelling happens first.

Frequently asked questions

What is a bridging loan and how does it work?

A bridging loan is a short-term home loan that lets you buy your next home before you sell your current one. The lender combines your existing mortgage and the new purchase into one peak debt, you sell your old home within a set period, and the sale proceeds reduce the loan to an end debt that continues as a normal home loan.

How long does a bridging loan last?

Up to twelve months at the lenders on our panel that write bridging, whether or not your current home has sold. A few limit open bridging to six months where no contract has been exchanged. Extensions are sometimes considered, but you can’t count on one.

Do you pay two mortgages with a bridging loan?

Not in the usual sense. You pay interest only during the bridging period, and around half the lenders on our panel that write bridging will capitalise that interest for up to twelve months instead of taking monthly payments. Normal principal and interest repayments start on the end debt once your old home sells.

How much equity do you need for a bridging loan?

Enough to keep your peak debt at or under 80% of the combined value of both properties at most lenders on our panel; one or two will go to 85% with mortgage insurance. Lenders also need to be satisfied you can service the loan, which most measure against the end debt and a few against the full peak debt.

What happens if my house doesn’t sell in time?

The lender can apply a higher rate, require you to reduce the balance or take steps to sell the property, and any shortfall is added to your ongoing loan. Pricing realistically and listing early are the main protections.

Can I use a bridging loan to build a new home?

Sometimes. Around half a dozen lenders on our panel will bridge a build while you stay in your current home, with the sale period running up to twelve months and the construction cost sitting inside the end debt. The bridging clock generally starts at the beginning, not at construction completion.

Are bridging loans expensive?

They cost more than a standard home loan, mainly because you pay interest on a large peak debt for months, plus valuations on two properties and loan fees. The length of the sale matters more than the rate: a sale that takes nine months instead of three means six more months of interest on the full peak debt.

What is a swing loan?

Swing loan is the United States name for a bridging loan. In Australia the same product is called a bridging loan or bridging finance.

Talk to us before you sign

We have been arranging home loans since 2001 and work across a panel of 52+ lenders. Only some of them write bridging loans, and their rules differ widely. Before you bid, we can model your peak debt, end debt and total cost at a few realistic sale prices and timelines. Then we’ll tell you whether bridging is the right tool, or whether selling first, a deposit bond or a sequenced sale gets you there for less. Speak to our mortgage brokers in Western Sydney to talk it through.
