Selling Tips
Sell First or Buy First? How to Upsize in Adelaide (and How Bridging Loans Work)
30 October 2026 · Vin Sran · 7 min read
For many Adelaide homeowners, upsizing is a natural next step: a growing family, a home office, or simply more space to live. But it raises one of the most important financial decisions in any move: should you sell your current home first, or buy your next one first? The right answer depends on your equity, your borrowing capacity and how much risk you are prepared to carry. This guide explains the three main pathways, including how bridging loans work, so you can plan your move with confidence.
Selling first: certainty, with a timing trade-off
Selling before you buy gives you the clearest financial picture. Once your sale is unconditional, you know exactly what equity you have to put towards your next home, and your lender can assess your purchase on firm numbers rather than an estimate.
It also strengthens your position as a buyer. An offer that is not conditional on another sale is generally more attractive to sellers, particularly when several buyers are interested in the same property.
The trade-off is timing. If you have not secured your next home by settlement, you may need short-term rental accommodation, storage and two moves. These risks can be reduced by:
- Negotiating a longer settlement period on your sale to give yourself more time to buy.
- Asking your buyer whether you can lease the property back for a short period after settlement.
- Starting your search well before you list, so you are ready to act quickly.
Buying first: securing the right home
Buying first allows you to secure the right property without the pressure of a deadline, and usually means only one move. It suits buyers with substantial equity who are confident their current home will sell within a reasonable timeframe and at a realistic price.
The key risk is that you commit to a purchase before your sale price is known. If your home takes longer to sell than expected, or sells below your estimate, you may carry two properties for longer and have less equity for the new one than you planned.
Some buyers manage this risk by making an offer subject to the sale of their existing home. The purchase only proceeds if your home sells, which protects you financially. However, sellers often prefer unconditional offers, so this approach tends to work best when there is limited competition for the property.
How a bridging loan works
A bridging loan is short-term finance that allows you to buy your next home before your current home is sold. Your lender temporarily combines the debt on both properties into one structure until your sale settles. Two figures are central to how it works:
- Peak debt: the highest amount you owe during the bridging period. It is generally your existing loan plus the loan for your new purchase, and may include costs such as stamp duty and fees.
- End debt: the loan that remains once your current home sells and the sale proceeds are applied. This becomes your ongoing home loan, usually on principal and interest repayments.
Bridging periods typically run for six to 12 months, depending on the lender. During that time, repayments are usually interest-only, or the interest is capitalised (added to the loan balance) so you are not making repayments on two properties at once. Lenders will generally assess:
- the equity in your current home and the combined loan-to-value ratio (LVR) across both properties;
- your income and ability to service the end debt;
- a conservative estimate of your current home’s sale price.
A simple worked example
The figures below are illustrative only, to show how the calculation works.
| Item | Amount |
|---|---|
| Existing home loan | $250,000 |
| New home purchase price | $950,000 |
| Purchase costs (stamp duty, fees) | $50,000 |
| Peak debt | $1,250,000 |
| Net proceeds from selling current home | –$680,000 |
| End debt (ongoing loan) | $570,000, plus any capitalised interest |
In this example, the lender would look at whether the $1.25 million peak debt fits within its limits against the combined value of both homes, and whether you can comfortably repay the $570,000 end debt. This is why an accurate, evidence-based estimate of your home’s value is essential before you commit.
The costs and risks of bridging finance
Bridging finance can be an effective tool, but it is not the right fit for every household. Before proceeding, consider:
- Sale timing: the longer your home takes to sell, the more interest accrues on the peak debt.
- Sale price: a lower-than-expected result increases your end debt.
- Higher costs: bridging rates and fees can be higher than a standard home loan.
- Deadlines: if your home is not sold within the bridging term, lenders may apply a higher rate and can require the property to be sold.
Speak with your bank or a licensed mortgage broker to understand the full costs, your borrowing capacity and the lender’s conditions before you sign a contract.
Other ways to bridge the gap
Bridging finance is one option, but not the only one. Depending on your circumstances, you may also consider:
- Aligning settlements: negotiating your sale and purchase so they settle on the same day, or close together.
- A subject-to-sale offer: protects you if your home does not sell, though it may make your offer less competitive.
- A deposit bond: can be used in place of a cash deposit when your funds are tied up in your current home.
- Accessing existing equity: some owners refinance to release equity for a deposit, subject to the lender’s assessment.
Selling first, buying first or bridging: a comparison
| Sell first | Buy first | Bridging loan | |
|---|---|---|---|
| Budget certainty | High | Low | Moderate |
| Risk of holding two homes | None | High | Managed within the bridging term |
| Risk of moving twice | Possible | Low | Low |
| Strength of your offer | Strong (unconditional) | Weaker if subject to sale | Strong |
| Additional costs | Possible rent and storage | Double holding costs | Bridging interest and fees |

South Australian rules that affect your timing
Cooling-off period. In South Australia, a buyer’s cooling-off right ends at the end of the second clear business day after the Form 1 (vendor’s statement) is served. There is no cooling-off period for properties bought at auction, so make sure your finance is approved before you bid.
Settlement is negotiable. The settlement date is agreed in the contract. Coordinating your sale and purchase settlements is one of the most effective ways to avoid holding two properties.
Prepare your documents early. Because the buyer’s cooling-off period runs from when the Form 1 is served, having your disclosure documents ready early helps your sale progress quickly and with greater certainty.

Frequently asked questions
Is it better to sell or buy first in Adelaide?
It depends on your equity, borrowing capacity and appetite for risk. Selling first provides budget certainty, while buying first secures the property you want but may mean holding two homes for a period.
How long can a bridging loan last?
Bridging periods are typically six to 12 months, depending on the lender. Your lender will want to be confident your current home can sell within that time.
What is the difference between peak debt and end debt?
Peak debt is the total you owe while holding both properties. End debt is the loan remaining after your current home sells and the proceeds are applied.
Can I buy a house subject to selling my own in SA?
Yes, if the seller agrees to include that condition in the contract. It reduces your risk but can make your offer less competitive.
How do I find out what my home is worth before I buy?
Request a sale appraisal from a local agent. It is based on recent comparable sales and current buyer demand in your area, and gives you a realistic figure for planning.
