Buying your next home: sell first, buy first, or bridge

The short answer

Nobody has to sell first. It's a choice between three ways of moving, and a fourth option that isn't a move at all.

Sell first and buy with certainty and two removalists. Buy first on a bridging loan and pay a cost of convenience for moving once. Line both settlements up on the same day and pay nothing extra, if four strangers are all on time. Or keep the place as a rental and buy the next one off the equity. Which of those is open to you comes down to two numbers a bridging lender cares about, the peak debt and the end debt, and one number you don't control, the bank's valuation. This page is the four paths in order, the numbers underneath them, and the costs people leave out of the spreadsheet.

The three ways to move house

Most people ring me with the sequence already decided: sell, rent for a bit, then buy. That's the version their parents did, and it's the version a bank branch will nod along to because it's the simplest loan to write. It's also the most disruptive way to move, and for anyone who has owned their place for a few years it's usually not the only option. Do I have to sell before I buy is the single most common next-home question I get, and the answer is no, you have three paths, and each one trades money for certainty in a different place.

1. Sell first, then buy. One loan at a time, with a gap in between. You know exactly what you've got to spend because the sale has settled and the money is in the account. The cost isn't on the loan, it's on your life: rent or a stay with family, two moves, and a purchase made under time pressure because the lease is running out. The other cost is the one nobody prices: the place you would have bought comes up while you're still on the market, and you watch it go.

2. Buy first, with bridging. A lender funds the whole next purchase before your current place has sold, on the premise that it sells within a set window, generally six to twelve months. For a period you're carrying both properties under one bigger loan, and you pay a little bit of a premium for it as a cost of convenience. What you get for that premium is the version of moving most people actually want: you find the place, you make an offer that isn't subject to selling anything, you settle on a date you chose, you move once, and then you sell without a deadline hanging over the campaign. The thing that opens this door is equity, which is why it's a real option for someone five years into their loan and a hard one for someone who bought last year with a small deposit.

3. Both on the same day. A simultaneous settlement. Two contracts with matching settlement dates, your buyer's money pays out your loan, what's left becomes the deposit on the new place, and the new lender funds the rest, usually within the same hour on the settlement platform. No second loan, no extra interest. If it lands, it's the cheapest way to move house there is. I've seen it work maybe two or three times, because it depends on your buyer's bank, your buyer's conveyancer, your vendor's discharge and your own loan all being on time on one date, and when any one of them slips, penalty interest can land on you for a delay you didn't cause. Same day buy and sell goes through why it so rarely happens, and why plenty of people pay for bridging instead.

There's a shortcut people try between paths one and two: making an offer subject to sale. You can, and owners accept them all the time in a slower market or on a place that has been sitting. But when there's another offer on the table without the condition, yours sits at the bottom of the pile even if it's a little higher, because the agent works for the seller and a sale that's hostage to your sale is the riskiest one they can recommend. Bridging is how people make an unconditional offer without selling first.

The two numbers every bridging lender looks at

A bridging loan is one loan that changes size. On the day you settle the purchase it's at its biggest: the loan you already had, plus the whole price of the new place, plus the costs of buying it. That's the peak debt. When the old place sells, the proceeds come off the top and the loan drops to whatever is left on the new home. That's the end debt, and it's the loan you actually live with for the next 30 years.

Illustrative numbers, not a quote. A home worth $700k with $300k owing, buying for $900k with about $50k of stamp duty and costs. Peak debt is $1.25 million while you own both. End debt once the $700k sale clears is $550k. The peak is more than double the end debt, and every decision a lender makes about a bridge comes back to which of those two figures it's prepared to test you on. Some lenders assess your income against the peak, as if you were carrying $1.25 million for 30 years, and for most households that answer is a flat no. Others test the end debt, on the basis the peak only exists for a few months. A few sit in between and test the end debt plus the interest the bridge will add before the sale. Same household, same two properties, three different answers, and the one thing that most often turns a declined bridge into an approved one isn't more income. It's savings shown as a repayment buffer for the bridging period.

The peak is fixed the day you settle. The end debt isn't, and three things push it around, all in the same direction. If the sale fetches $650k instead of $700k, the whole $50k shortfall lands on the loan you keep. If the interest is added to the loan instead of paid monthly, every month until the sale goes on top. If the campaign takes nine months instead of three, that's six more months of interest. Whether you make repayments during the bridge depends on the lender: some want interest-only repayments on the peak out of your pocket each month, others capitalise it and take it out of the sale proceeds, and a few split the two. None of that changes what the bridge costs in total. It changes where the money comes from, your pay or your sale.

Then the number you don't control. Both figures are built on what the bank says your current place is worth, and the bank won't use the agent's appraisal. Bank valuations run on settled sales data, so they lag the market, and a $50k gap between the appraisal in your head and the valuation on the file changes the equity, the peak and whether lenders mortgage insurance is back in the maths. I run the lenders' own valuation tools on your place before anything goes near an application, so the plan is built on the number the bank will actually use.

The fourth path: keep it as a rental

Selling isn't the default. If you're interested in holding property for the longer term, keeping the first place as a rental is often the preferred route: you already own it, you know it, and a tenant helps carry it while it grows. The deposit for the next place then comes from the one you already own. Illustrative again: a place worth $700k with $450k owing can be taken to 80% of value, which is $560k, releasing $110k for the deposit and costs on the next purchase without a dollar of new savings. That's the whole answer to do I need 20% again: no, if the equity is there.

Two tests decide whether the fourth path is open. The first is the one people skip: equity isn't borrowing power. You've got to borrow that equity to use it, and to borrow it you've got to show the income to repay it, on top of the new loan, over 30 years. You could have all the equity in the world and still fail that test. The second is the rent. The bank doesn't count 100% of what you expect the tenant to pay. It shades it, and it adds the costs of owning a rental on the other side, so a property that pays for itself in your head can still fail on paper. That's not the bank being difficult. It's the bank assuming a vacancy and a repair bill. If the numbers pass, you hold both. If they don't, you're back to the three paths above, and there's no shame in that.

One honest note on releasing equity. Pulling $110k out of the current home means the loan on it goes up by $110k, and so does the repayment. Where the old place becomes a rental, the rent helps and the interest on the released portion is generally deductible against it, which is an accountant's conversation worth having before you decide rather than after. The version of this that goes wrong is releasing equity to the maximum, buying at the top of the borrowing number, and having no buffer in either loan. Two mortgages with no fat is a stressful way to live, and if the plan is really to sell the old place anyway, a bridge is usually the cleaner structure than a release you'll unwind in six months.

The costs that don't make it into the spreadsheet

Selling costs. I'm no real estate agent, but when I run next-home numbers I use a conservative 3% of the sale price as the budget for the agent and selling the home. On a $700k sale that's $21k set aside, and it comes out of the proceeds before you see a dollar, so it changes the deposit you walk into the next purchase with. If you're bridging, it changes your end debt. Get two agents to quote in writing, all-in, then use the higher one.

Stamp duty on the next place. The cost people leave out when they compare moving with staying put and renovating. On a bigger next home it can be more than the agent's fee, and if you're bridging it's inside the peak debt, so the bank has to fund it too. Leave it out and the peak is wrong before you start.

The deposit you can't reach yet. Your deposit is tied up in the house you haven't sold. A deposit bond is the piece of paper that stands in for it: a guarantee to the agent and the conveyancers that you're good for the deposit, for a fee, issued once the bond provider can see the money is clearly coming on settlement day. It fixes a timing problem, not a deposit problem, and it needs a formal or conditional approval behind it, which is why the timing of the deposit deadline in the contract drives when we apply for it.

LMI, all over again. If the equity and the sale proceeds don't get you to 20% of the next purchase, the new loan sits above 80% of value and lenders mortgage insurance is back, unless your occupation qualifies for a waiver. It's the same maths as a first purchase, just with a bigger loan behind it, and a soft valuation on the old place is the usual way people end up there without expecting to.

The renovation. If the next place needs work and you already own with equity, we can borrow above the purchase price and earmark the extra for it, usually as its own split. Most lenders release renovation money without evidence up to a cap, from no limit at all down to about a hundred thousand at the tightest, and above that or above 80% of value they want quotes or a builder's contract. A few restrict it to non-structural work and push anything structural into a construction loan.

And the one that isn't a cost so much as a timeline: exchange is the point of no return and settlement is when the money moves, generally 30 to 60 days later. On a next-home purchase you're managing two of each, and the dates have to be written into both contracts, not hoped for.

Same move, different lender, different answer

Here's the part a branch can't show you, because a branch only has one set of rules: bridging is the least standardised product on the panel. The same two properties and the same payslips get genuinely different answers depending on where you walk in, on five dials.

Which figure gets tested. Peak, end, or end plus interest, as above. This one alone decides whether a bridge is available to you at all. How long the window runs. Most lenders sit somewhere between six and twelve months, and twelve is a ceiling, not a target: if the sale runs past it, the arrangement gets reviewed, repayments can start, the rate can change, or the lender can ask what the plan is. Whether the interest is paid or added. Monthly interest-only on the peak proves month by month that you can carry it and keeps the end debt exactly where everyone expected. Capitalising it is quieter and compounds, so on a short bridge it's modest and on a slow campaign it's the difference between the end debt you planned and the one you get. Who holds the old loan. Usually the bridging lender refinances your existing loan so both properties sit with one lender. If your current loan stays where it is, its repayments keep running in parallel with whatever the bridge asks of you. And the equity release caps, if you're keeping the place instead: under 80% a good chunk of the panel will release with no dollar cap and just a purpose recorded, others stop at a set figure, and above 80% nearly all of them want a purchase contract for every dollar.

Which is why "can we get a bridging loan" is never a yes or no. It's "which lenders test the number we can actually pass, and what does a month of their bridge cost." None of that is on a comparison site. Which is the job.

The questions, one by one

Each of these has its own full answer, in the order they tend to come up. Find where you're at and go down a level.

Do I have to sell my current home before I buy the next one?

No. Bridging lets you borrow the full amount for the next place before the current one sells, generally inside a twelve month window, for a cost of convenience. The three paths side by side.

Can I make an offer before I've sold my place?

Yes, subject to sale. It sits at the bottom of the stack when there's a cleaner offer next to it, and the three alternatives are bridging, selling first, or a same day settlement.

Do we need a bridging loan if buying and selling on the same day?

No. A simultaneous settlement runs both on one day with nothing extra to pay. It needs four strangers to be on time on one date, which is why I've seen it land maybe two or three times.

Can we afford to buy before we sell? Peak debt versus end debt

Peak debt is everything you owe while you own both. End debt is what's left after the sale. Which one the lender tests you on decides whether the bridge is approved, and savings often matter more than income.

Do I make repayments during bridging finance?

Depends on the lender. Some want interest-only repayments on the peak each month, others add the interest to the loan and take it out of the sale. Same total cost, different cash flow.

Do I have to sell, or can I keep this place as a rental?

You can keep it if your income plus the shaded rent carries both loans. The deposit for the next place often comes out of the equity in the first one.

Do I need to save a full 20% deposit again for my next home?

No. Equity is the deposit you didn't have to save. Short of 20% in cash or equity and the new loan sits above 80%, so LMI is back unless your occupation qualifies for a waiver.

What does it actually cost me to sell a property?

Budget a conservative 3% of the sale price for the agent, then add the stamp duty on the next purchase, which people forget and which can be the bigger number.

Can I borrow extra at purchase to fund the renovations?

If you already own with equity, yes, above the purchase price and usually as its own split. Each lender caps it differently and wants quotes past a point.

What is a deposit bond?

A guarantee that stands in for the cash deposit when your money is tied up in the house you haven't sold. Fixes a timing problem, not a deposit problem.

Bank valuation or agent appraisal: which one counts?

The bank's own valuation, every time. It runs on settled data and lags the market, and it sets your equity, your peak debt and whether LMI is in play.

The honest part

Bridging isn't for everyone, and I'd rather say so here than halfway through an application. If you bought recently with a small deposit, the gap between value and debt may not be enough to carry a second property, and selling first is the cleaner path. That's not a judgement, it's arithmetic. If your income can't pass any lender's version of the peak or end debt test and there's no savings buffer to show, the bridge isn't available, however much sense the move makes. And if the old place is likely to sell slowly or for less than the agent reckons, every month and every dollar of shortfall lands on the loan you keep for 30 years, so plan the sale price low and list early.

The other honest bit is about the same day version. It's the cheapest way to move and I'll always check whether the dates can be written in. But I won't build your whole plan on four strangers being on time, and if the sale side falls over a fortnight out you're a bridging client whether you planned it or not. Having that conversation before you exchange is a lot easier than having it in the last two weeks.

What to bring, and the question to ask

Four things. Your current loan statement and a realistic idea of what your place is worth, which give me the equity. The price range you're buying in and a conservative sale figure, which give me the peak debt and the end debt in about two minutes. Your savings balance, because it decides which lenders would test the peak and whether the buffer you've got is enough to matter. And a couple of payslips, because whichever path you pick, the end debt still has to service like a normal loan. If you've already got a contract on either side, bring it: the settlement date and the price are the two numbers everything hangs off.

Then the question isn't "do we have to sell first." It's "what does buying first cost us per month, can we carry it, and is that worth not moving twice." Three numbers and an honest answer about how you want the next six months to feel. Most people know their answer in about five minutes once those are on the table, and if the answer is sell first, I'll say so.

Thinking about the next place before this one's sold?

Send me your loan statement, a rough value on your place and the price range you're looking at, and I'll map sell first against buy first against keeping it: the equity, the peak debt, the end debt, and what a month of the bridge would cost. Before anything goes near an application.

Common questions about buying your next home

Can I buy a new house before I sell my current one?+

Yes, with bridging finance. A lender funds the whole next purchase before your current place sells, on the premise that it sells within a set window, generally six to twelve months. You carry both properties under one bigger loan for that period and pay a premium for the convenience, in interest on the larger debt and at some lenders a higher rate or a fee on the bridging portion. It depends on having enough equity in the current home to support the combined debt.

How does a bridging loan work in Australia?+

A bridging loan is one loan that changes size. On the day you settle the purchase it's at its biggest, the peak debt: your existing loan plus the full price of the new place plus purchase costs. When the old place sells, the proceeds come off and the loan drops to the end debt, which is what you repay over the normal term. Interest is charged on the peak until the sale, either paid monthly or added to the loan, depending on the lender.

Is it better to sell first or buy first?+

Selling first is the cheapest on paper and the most disruptive in real life: you know your budget, but you rent in between, move twice and buy under time pressure. Buying first with bridging costs a few months of interest on a bigger debt and gets you one move, an unconditional offer and a sale with no deadline. Thin equity or a slow local market pushes people to sell first. A few years of ownership and a sellable home make buying first a real choice rather than a rule.

Do I need a 20% deposit for my second home?+

No. If your current property is worth more than the loan on it, that gap is equity, and it can be released to fund the deposit on the next place without new savings. If cash plus equity comes to less than 20% of the next purchase, the new loan sits above 80% of the property's value and lenders mortgage insurance generally applies, unless your occupation qualifies for a waiver. The bank still has to be satisfied you can repay both loans.

Can I keep my first home as an investment and buy another?+

Often, yes. The bank runs your income plus a shaded portion of the expected rent against the existing loan and the new one, and if it passes you hold both, usually with the deposit for the next place released from the equity in the first. Rent isn't counted in full and the costs of owning a rental go on the other side of the ledger, so a property that pays for itself in your head can still fail on paper. The tax treatment is a question for your accountant before you decide.
