Buying Off the Plan in NSW: What to Watch Out For

Buying off the plan (OTP) means purchasing a property before it's built — typically an apartment or townhouse — from a developer using architectural plans and display suites. You pay a 10% deposit at exchange, then wait 1–3 years for the building to complete before settling the balance.

For first home buyers, OTP purchases can unlock lower entry prices and new-build stamp duty savings. But the risks are real — and different from buying an established home.

Why Buyers Consider Off the Plan

• Lower entry price: Developers lock in today's price — in rising markets, you could be settling at a below-market price
• Time to save: The 1–3 year build period gives you time to grow your deposit
• First Home Owner Grant eligibility: New builds qualify for the $10,000 FHOG in NSW
• Stamp duty concession: Based on the contract date (pre-build), not settlement — first home buyers may pay no duty if the price is under $800,000
• Brand new warranties: Builder's warranty covers defects for 6 years (structural) and 2 years (non-structural)

The Risks You Must Understand

1. Valuation Gap at Settlement

Your lender values the property at settlement — not at the contract date. If property values fall, or the finished product doesn't match the contract price, your lender may value it below what you've agreed to pay.

This is the single biggest risk of OTP purchases. You must either save extra cash or purchase in a suburb where values are unlikely to fall during the build period.

2. Sunset Clauses

Most OTP contracts include a sunset clause — a date by which the developer must complete the project. If they don't, either party can rescind the contract and the deposit is refunded.

In a rising market, unscrupulous developers have used sunset clauses to deliberately delay construction — then rescind contracts to resell at higher prices. NSW introduced legislation to restrict this practice, but sunset clause terms still vary significantly between contracts.

What to check: Who can trigger the sunset clause? Can the vendor rescind without buyer consent? What compensation applies if rescinded by the developer?

3. Finance Approval Expiry

A pre-approval granted today will expire (typically 90 days). You'll need a fresh finance approval at settlement — 1–3 years from now. Your income, employment situation, or lending environment may be different.

4. Changes to the Final Product

OTP contracts typically allow the developer to make "minor variations" to finishes, layouts, or inclusions. The apartment you receive may differ from the display suite.

What to check: What variations are the developer permitted to make? Is there a minimum floor area guarantee? Are car spaces and storage guaranteed on title?

5. Developer Insolvency

If the developer becomes insolvent during construction, your 10% deposit may be at risk depending on how it was held. In NSW, deposits must be held in trust or covered by deposit bond insurance — but recovery during insolvency can be slow and uncertain.

Key Contract Terms to Check

• Sunset clause date and who can trigger it
• Permitted variations clause — how much can change?
• Car space and storage — are they on title or licence?
• Defect liability period and builder's warranty details
• Deposit holding arrangements (trust vs developer account)
• Completion definition — when does the clock start for settlement?

Stamp Duty on Off-the-Plan Purchases

In NSW, stamp duty on OTP purchases is calculated on the contract price at the date of exchange — not the final value at settlement. This is advantageous because:

• First home buyers under $800,000 pay zero stamp duty at contract date
• If the property's value increases before settlement, you're not taxed on that uplift

However, if the contract price is above the $800,000 threshold at exchange, the full or scaled duty applies regardless of what happens later.
