Buying off-the-plan in Rushcutters Bay means committing to a property you will not see finished for 18 to 24 months, in a suburb where 98% of housing stock is apartments and supply can shift quickly.
The challenge is not just waiting for construction to complete. It is making sure your finance still works when settlement day arrives, and that the finished apartment values at or above the price you agreed to pay years earlier. Off-the-plan purchases carry specific risks around valuation shortfalls, loan pre-approval expiry, and income changes between contract and settlement. If you are self-employed or your circumstances shift during the construction period, those risks become more pronounced.
What Makes Off-the-Plan Finance Different from Buying Established Property
When you buy an established home, you apply for finance, exchange contracts and settle within 30 to 60 days. When you buy off-the-plan, you sign a contract today but settle in 18 months or longer, and your lender will not provide an unconditional approval that lasts that long.
Most lenders issue conditional approval valid for 90 to 120 days. That approval is based on your income, deposit, credit history and the property valuation at the time you apply. For an off-the-plan purchase, the property does not exist yet, so the valuer assesses the contract price against comparable sales and the development plans. The lender then issues a conditional approval noting that a final valuation will be completed at practical completion, and your financial position will be reassessed before settlement.
Between exchange and settlement, several things can change. Variable rates can rise or fall, affecting your borrowing capacity. Your income can change, particularly if you are self-employed and your most recent tax return shows lower profit. The apartment market in Rushcutters Bay can soften or strengthen. If the final valuation comes in below the contract price, you will need to cover the shortfall with additional savings or accept a higher loan-to-value ratio, which may trigger Lenders Mortgage Insurance or require you to renegotiate your loan structure.
Valuation Risk in a Unit-Dominated Precinct
Rushcutters Bay is almost entirely apartments, with negligible house stock and a current unit median around $1,211,000. The precinct sits between Kings Cross and Edgecliff, within walking distance of the harbour foreshore and Rushcutters Bay Park, and attracts a high proportion of renters given its 63% renter density and strong unit rental yield of approximately 4.76%.
When you buy off-the-plan in a suburb with this profile, valuation risk is driven by two factors: how many similar apartments are completed at the same time, and whether the market has moved in your favour or against you during the construction window. Consider a professional buying a two-bedroom apartment off-the-plan in a development near New South Head Road, with a contract price of $1,150,000 and a 10% deposit of $115,000. At the time of contract, the valuer assesses the unbuilt apartment at $1,150,000 based on comparable sales of existing stock in the area. Eighteen months later, two other developments complete within 500 metres, adding 90 apartments to the local supply. Comparable sales over the preceding three months show a median of $1,080,000 for similar two-bedroom stock. The final valuation comes in at $1,100,000. The lender will only lend against the lower valuation, leaving a $50,000 shortfall the buyer must fund from savings or negotiate as part of a revised loan structure with a higher LVR.
This scenario is not hypothetical. In high-density precincts where multiple developments reach completion in overlapping timeframes, valuations can compress if demand does not absorb the new supply quickly enough. Buyers who do not have additional savings to cover a potential shortfall face either renegotiating finance at a higher LVR, or in the worst case, being unable to settle.

How Sunset Clauses Affect Your Finance Timeline
Every off-the-plan contract includes a sunset clause, which sets a long-stop date by which the developer must reach practical completion. If the development is not completed by that date, either party can rescind the contract and the buyer receives their deposit back, usually without penalty.
Sunset clauses in NSW are commonly set at 24 to 36 months from the contract date. For buyers, the sunset clause provides an exit if construction is significantly delayed. For developers, it provides certainty that they can rescind and resell if market conditions improve sharply and the original contract price no longer reflects current value. Changes to NSW legislation in recent years have tightened the conditions under which developers can exercise sunset clauses to prevent rescissions motivated purely by rising prices, but the clause remains a feature of every contract.
From a finance perspective, the sunset clause determines how long your approval needs to remain flexible. If your contract has a sunset date 30 months out, you need to be confident your financial position will support a loan application reassessed at that time. If you are self-employed and your income fluctuates year to year, or if you plan to change jobs, take parental leave, or reduce your working hours during that period, your borrowing capacity at settlement may differ from your capacity at contract.
Some buyers obtain pre-approval at contract and then reapply closer to settlement. Others work with a broker to structure the loan application upfront in a way that anticipates potential changes, such as using a two-year average of self-employed income rather than the most recent year, or splitting the loan between variable and fixed products to manage interest rate risk during the construction period.
Structuring Your Deposit and Holding Costs During Construction
Most off-the-plan contracts in NSW require a 10% deposit, paid in stages. A typical structure is 5% on exchange, a further 5% within 90 days, and the remaining 90% on settlement. During the construction period, you do not make loan repayments because the loan has not settled, but you also do not have access to the property or any rental income.
If you are buying an investment property off-the-plan, you carry the holding cost of your deposit without receiving rent for 18 to 24 months. If you are buying as an owner-occupier and currently renting, you continue paying rent while your deposit sits in the contract. Either way, the construction period is a dead-money phase where your capital is committed but not working.
For this reason, off-the-plan buyers in Rushcutters Bay often maintain a separate savings buffer for settlement costs and potential valuation shortfalls, rather than committing every available dollar to the deposit. Stamp duty, legal fees, and lender costs are all due at settlement, and if you also need to cover a $30,000 to $50,000 valuation gap, you want that flexibility available without needing to sell other assets or borrow from family at short notice.
Should You Fix Your Rate Before Settlement
One question that comes up regularly is whether you can lock in a fixed rate months before settlement. The short answer is no. Lenders will not allow you to lock a fixed rate until your loan is formally approved and within 90 days of settlement, because they cannot hold a fixed rate allocation open for 18 months while construction proceeds.
What you can do is structure your loan application to include a fixed component at the time of final approval, typically three to four months before the expected settlement date. If you want certainty on your repayments once the loan settles, you can apply for a split loan with part fixed and part variable, giving you stability on a portion of the debt while retaining flexibility and offset access on the variable portion.
If rates have moved significantly between contract and settlement, this can work in your favour or against you. If the cash rate has fallen, as it did in February when the RBA cut to 3.85%, you may settle into a lower variable rate than you anticipated at contract. If rates have risen, your repayments will be higher than your original budget, which is another reason to stress-test your borrowing capacity with a buffer of at least 1% to 2% above current rates when you first apply.
What Happens If Your Income Changes Before Settlement
If you are self-employed, your most recent tax return is the primary document lenders use to assess your income. For an off-the-plan purchase, that means the tax return you lodge in the year leading up to settlement is the one that determines your borrowing capacity when the lender reassesses your application.
Consider a buyer who exchanged contracts in mid-2025 on a one-bedroom apartment off-the-plan in Rushcutters Bay, with settlement expected in late 2026. At the time of contract, their most recent tax return showed a net business income of $145,000, supporting a loan of $870,000 at an 80% LVR on a $1,090,000 purchase price. By the time settlement approaches, they have lodged their next tax return, which shows a net income of $110,000 due to a period of lower business activity. When the lender reassesses the application three months before settlement, the reduced income lowers their borrowing capacity to around $660,000, leaving a $210,000 shortfall they cannot cover.
In this situation, the buyer has three options: find additional savings or a guarantor to cover the gap, negotiate a higher LVR and pay LMI, or fail to settle and lose their deposit under the contract terms. The best protection is to maintain or grow your assessable income during the construction period, and to work with a broker who can structure the application to use averaging or other methods that smooth income volatility where the lender permits it.

Frequently Asked Questions
Can I lock in a fixed interest rate before my off-the-plan property settles?
No, lenders will not let you lock in a fixed rate until your loan is formally approved and within 90 days of settlement. You can structure your loan to include a fixed component at final approval, typically three to four months before settlement.
What happens if the apartment values below the contract price at settlement?
The lender will only lend against the lower valuation, and you will need to cover the shortfall from your own savings or accept a higher loan-to-value ratio, which may trigger Lenders Mortgage Insurance. If you cannot cover the gap, you may be unable to settle.
How long does off-the-plan pre-approval last?
Most lenders issue conditional approval valid for 90 to 120 days. For off-the-plan purchases, the lender will reassess your income, credit position and the property valuation at practical completion before providing final approval.
What is a sunset clause in an off-the-plan contract?
A sunset clause sets a long-stop date by which the developer must complete the property. If construction is not finished by that date, either party can rescind the contract and the buyer receives their deposit back, usually without penalty.
Do I pay loan repayments during the construction period?
No, you do not make loan repayments during construction because the loan has not settled. You also do not receive rental income or occupy the property until settlement, so your deposit is committed but not earning a return during this period.
