Your Guide to Buying Off The Plan Property

Long Saad Woodbridge’s property law team specialises in representing both developers and purchasers considering buying off the plan, ranging from small-scale land subdivisions to large mixed-use developments across Australia.

Our extensive experience has underscored the critical points that buyers need to be aware of at the outset of their property search. Setting expectations early regarding what can be expected from a legal perspective is paramount, making a knowledgeable and specialised property lawyer an essential partner for a successful transaction.

Key Points when Buying Off The Plan Property

Before you embark on your journey to buying off the plan property, there are crucial aspects to consider:

Sunset Dates

Every contract should have a “sunset date“, which is the latest date by which the developer must register the plan, in order for settlement of the purchase to occur. Without this date, purchasers can get strung along for years on end without any certainty. A sunset date provides a timeframe for the purchaser to choose not to proceed with the purchase, and get back their deposit.


As the developer does not have control over what requirements and changes councils, surveyors and other stakeholders may require, plans may be subject to change. However, off the plan contracts should contain a condition that limits these changes so that they must be reasonably required, and also that the area/size of the property cannot be reduced by more than a fixed percentage from the initial plans. The national industry standard is 5%.

Settlement Timeframe

It is important that a lawyer negotiates a practical timeframe for settlement to occur, once the plan is registered. This ranges from 7 to 28 days, and we generally like to see 14 to 21 days, as this time is used for the bank to finalise a loan and finance, and for the necessary legal steps to take place.

GST and Capital Gains

Most contracts will require the purchaser to withhold a percentage of the purchase price on account of the developer’s Goods and Services Tax (GST) and Capital Gains Tax (CGT) liabilities, and pay this directly to the ATO. It is important that the purchaser’s lawyer is aware of these requirements to ensure compliance, noting that the onus is on the purchaser.

Understanding the Risks Involved

Buying a brand-new home off the plan does however come with some risks and considerations. It’s important to understand these risks, and be well-prepared to deal with them should they arise. Buying off the plan risks include both financial and time-delay risks.
