What is a Put and Call Option?

A put and call option is a two-part agreement used in property transactions that gives:

  • The buyer (call option): The right, but not obligation, to purchase the property at an agreed price within a set timeframe
  • The seller (put option): The right to force the sale to the buyer if the buyer hasn't exercised their call option by the deadline

This structure is commonly used in development site transactions because it gives the developer time to obtain DA approval and finance before committing to the purchase.

How It Works in Practice

Step 1: Option Agreement

The developer pays an option fee (typically 1-3% of the agreed purchase price) for the right to purchase your property within a defined period (often 12-18 months).

Step 2: Option Period

During this period, the developer pursues DA approval, conducts due diligence, and arranges finance. You continue to own and occupy the property.

Step 3: Exercise or Expiry

At the end of the option period:

  • If the developer exercises the call option, a binding contract of sale is created at the pre-agreed price
  • If the developer doesn't exercise, you can exercise the put option to force the sale, or the option simply expires
  • If neither party exercises, the option lapses and you keep the option fee

  • Upfront option fee: You receive a payment (usually non-refundable) regardless of whether the sale proceeds
  • Agreed price: The purchase price is locked in upfront, protecting you from market falls
  • Put option protection: If the developer doesn't proceed after obtaining DA, you can force the sale
  • Continued occupation: You remain in the property during the option period
  • Limited obligation: Until the option is exercised, there's no binding contract of sale

Disadvantages for Sellers

  • Property is tied up: While the option is on foot, you can't sell to anyone else
  • Opportunity cost: If the market rises significantly, you're locked into the agreed price
  • Stamp duty timing: The option fee may have stamp duty implications
  • Complexity: Option agreements are more complex than standard contracts and require specialist legal advice

Key Terms to Negotiate

Put and Call vs Conditional Contract

Both structures serve a similar purpose — allowing the developer time to obtain approvals before committing. The key differences:

Stamp dutyDeferred until exercisePayable at exchange
DepositOption fee (smaller)Full deposit (5-10%)
