Buying off the plan: what to check before you sign

Off-the-plan contracts are not standard. Before you sign, understand the sunset date, deposit arrangements, what can change, and what your cooling-off position is.

Buying off the plan means committing to something that does not exist yet. The contract is where that risk is allocated — which is why it deserves proper legal review rather than a skim.

This is a checklist to work through with your own solicitor or conveyancer. It is general information, not legal advice, and it is not a substitute for having your specific contract reviewed.

The sunset date

Every off-the-plan contract has a date by which the plan must be registered or the building completed. Ask:

  • what is the sunset date, and is it realistic given the current stage?
  • what happens if it passes — who can rescind, and on what conditions?
  • what notice must be given, and what are my rights if the vendor seeks to rescind?

Your deposit

  • How much is payable, and when?
  • Where is it held, and in whose name?
  • Is a deposit bond or bank guarantee acceptable instead of cash?
  • On what conditions can it be released to the vendor before completion?

What can change

Off-the-plan contracts usually permit some variation. Understand:

  • what tolerance applies to floor area, and what happens if the finished home falls outside it
  • which finishes and inclusions are fixed, and which are "or equivalent"
  • whether car parking, storage and unit numbering are fixed
  • what happens to the common property and amenity shown in marketing material

Cooling off and disclosure

In NSW, off-the-plan contracts carry specific disclosure requirements and cooling-off provisions. Your solicitor will explain what applies to your contract, what you have received, and what you should have received.

Practical checks

  • Get every representation that matters to you into the contract in writing.
  • Keep the marketing material you relied on, dated.
  • Ask what warranties apply on completion and how defects are handled.
  • Understand the strata or community-title arrangements and the estimated levies.
  • Talk to your lender early: valuation at completion, not at signing, is what matters.

Before you commit to one project

Compare at least two or three genuine alternatives at a similar stage. It is much easier to judge whether a contract is reasonable when you have seen more than one.
