You have found a bigger home, a better location, or you have simply outgrown your first place. The question that stops most Adelaide upgraders in their tracks is not whether to buy - it is how to manage the transition. Do you sell first and risk missing out on the next property? Buy first and carry two mortgages? Or keep the first home as an investment?
Each approach has different financial implications, and the right answer depends on your equity, income, risk appetite, and the current market conditions.
This is the safest path. You sell your current home, bank the equity, and then buy your next property knowing exactly how much you have available. There is no risk of carrying two mortgages and no pressure to sell quickly.
The downside is the gap between selling and buying. You may need to rent or stay with family for a few months. And in a rising market, the property you want might increase in price while you are waiting.
In Adelaide's current market, this approach works well when you are confident about finding your next property quickly and rental availability in your preferred area is reasonable.
A bridging loan lets you purchase your new home before selling the old one. You hold both properties for a short period - typically 6 to 12 months - while your existing home is on the market.
During the bridging period, most lenders charge interest on the combined debt but may allow interest-only repayments or even capitalise the interest (add it to the loan). Once your old property sells, the bridging component is repaid and you are left with a standard mortgage on the new home.
The risk is obvious - if your old property takes longer to sell or sells for less than you expected, you are carrying more debt for longer. Bridging works best when your existing property is in a high-demand area and likely to sell quickly.
This is increasingly popular in Adelaide, especially when the first property is in a strong rental area. Instead of selling, you keep it as an investment property and use your equity as a deposit for the new home.
The advantages are clear: you build a property portfolio, benefit from rental income, and potentially claim tax deductions on the investment property. The rental income helps service the second mortgage, and over time both properties should grow in value.
The challenges are also real. You need enough income to service both loans (lenders will assess at the full rate plus a buffer). You become a landlord with all the responsibilities that entails. And your equity position needs to support two properties without stretching to uncomfortable LVR levels.
Whether you are selling or keeping your first home, your equity is your deposit for the next purchase. The usable equity is typically 80% of your property's value minus your current loan balance.
For example, if your home is worth $700,000 and you owe $300,000, your usable equity is ($700,000 x 0.80) - $300,000 = $260,000. That is a substantial deposit for your next home.
If you sell your current home and buy a new one, ideally both transactions settle on the same day. This avoids the need for temporary accommodation or bridging finance. Your conveyancer can coordinate this, but it requires careful planning and some flexibility from all parties.
If a simultaneous settlement is not possible, even a short gap of a few days can be bridged informally by most lenders without requiring a formal bridging loan.
In South Australia, you can make an offer on a property that is subject to the sale of your existing home. This gives you a defined period to sell your property before the purchase contract becomes unconditional. It is a safer middle ground, though sellers in a competitive market may prefer offers without this condition.
Lendology's approach: We model every scenario with real numbers before you commit. Sell, keep, bridge - we show you the cash flow, the equity position, and the risk for each path. Book a free chat and we will map it out together.
Yes. Many Australians hold two mortgages - one on their home and one on an investment property. The lender will assess whether your income supports both repayments, plus a buffer. If you are keeping your first home as a rental, the expected rental income will be included in the assessment (usually at 80% of the market rent). Lendology models both scenarios so you can see what is affordable.
A bridging loan covers the gap between buying your new home and selling your old one. You effectively hold both properties for a short period (usually 6-12 months). During the bridging period, you typically make interest-only payments on the combined debt. Once your old property sells, the bridging loan is repaid and you revert to a standard mortgage on the new property. The risk is that if your old property takes longer to sell or sells for less than expected, you are carrying a larger debt for longer.
Selling first is the safer option - you know exactly how much you have to spend, and you avoid the stress of carrying two properties. But it means you may need temporary accommodation between selling and buying. Buying first gives you more time to find the right property and avoids a rushed purchase, but you carry the financial risk of holding two properties. The right choice depends on your financial position, the current market, and your risk tolerance.
