Option to Purchase (OTP) in Singapore: What Property Buyers Must Know

Written By Tamia Cleofas

When buying property in Singapore, one of the most important documents you will encounter is the Option to Purchase (OTP). This legal document grants a buyer the exclusive right to purchase a property within a specified period.

Understanding how the OTP works is crucial. Once the option is exercised, the buyer is legally bound to complete the purchase according to the terms stated in the agreement.

Because of its legal and financial implications, many buyers engage a conveyancing lawyer to review the OTP before exercising it.

Key Takeaways

  • An Option to Purchase (OTP) gives a buyer the exclusive right to buy a property within a fixed timeframe.

  • Buyers typically pay an option fee to secure the OTP.

  • Once the OTP is exercised, the sale becomes legally binding.

  • Missing OTP deadlines can result in losing the option fee.

  • A conveyancing lawyer should review the OTP before it is exercised.

What Is an Option to Purchase (OTP)?

An Option to Purchase is a legal agreement between a property seller and buyer that grants the buyer the right to purchase the property within a set option period.

The OTP typically contains:

  • Property details

  • Purchase price

  • Option fee amount

  • Exercise deadline

  • Completion timeline

If the buyer decides to proceed, they must exercise the option within the option period, usually by signing the OTP and paying the exercise fee.

How the OTP Process Works

Step 1: Seller Grants the OTP

The seller issues the OTP after the buyer agrees on a purchase price.

The buyer pays an option fee, typically:

  • 1% of the purchase price for private property

  • A fixed amount set by HDB guidelines for HDB resale flats

This option fee secures the property for the buyer during the option period.

Step 2: Option Period

The option period gives the buyer time to:

  • Conduct due diligence

  • Secure bank loan approval

  • Confirm CPF usage eligibility

  • Engage a conveyancing lawyer

For private property, the option period is usually 14 days.

Step 3: Exercising the OTP

If the buyer decides to proceed, they must:

  • Sign the OTP

  • Pay the exercise fee (typically making up 4% of the purchase price in total)

  • Submit the exercised OTP to their lawyer

Once exercised, the OTP becomes a binding Sale & Purchase Agreement.

What Happens If You Don’t Exercise the OTP?

If the buyer does not exercise the option before the deadline:

  • The OTP expires automatically

  • The seller keeps the option fee

  • The property can be offered to another buyer

This is why buyers must carefully review the OTP terms before committing.

Why a Conveyancing Lawyer Should Review the OTP

Before exercising the OTP, a conveyancing lawyer will:

  • Review the contractual terms

  • Check for unfavourable clauses

  • Confirm legal ownership and title

  • Advise on completion timelines

Once the OTP is exercised, backing out of the transaction can lead to serious financial consequences.

OTP vs Sale & Purchase Agreement

Many buyers assume the OTP is separate from the sale agreement. In practice:

  • The OTP becomes the Sale & Purchase Agreement once exercised.

  • The terms inside the OTP govern the transaction until completion.

Because of this, careful review is essential before exercising the option.

Common OTP Mistakes Buyers Make

Some of the most common errors include:

  • Exercising the OTP before securing financing

  • Misunderstanding option deadlines

  • Failing to review legal terms

  • Not engaging a conveyancing lawyer early

These mistakes can result in financial loss or failed transactions.

FAQs

1. Is the OTP legally binding?

The OTP becomes legally binding once the buyer exercises the option.

2. Can I negotiate OTP terms?

Yes. Certain terms may be negotiable before signing.

3. Can I withdraw after exercising the OTP?

Withdrawal is difficult and may result in financial penalties.
