Before You Grant the OTP: An HDB Seller Checklist

Key takeaways

• Register a valid Intent to Sell and observe HDB’s required seven-day period before granting an OTP.
• Confirm that the buyer has a valid HFE letter.
• Use the HDB-prescribed OTP for the resale transaction.
• Agree on more than price: review the deposit, application timing, completion expectations and any extension request.
• The Option Fee can be negotiated between S$1 and S$1,000; the Option Fee and Option Exercise Fee together cannot exceed S$5,000.
• Estimate loan repayment, CPF refund and other applicable amounts before relying on expected cash proceeds.
• Once the buyer exercises the OTP, both parties must coordinate their resale-application submissions carefully.

Background

An HDB resale transaction follows a prescribed sequence. The seller registers an Intent to Sell, markets the flat and negotiates with eligible buyers. Once the parties agree on the resale price and material terms, the seller may grant the HDB-prescribed OTP.

The OTP gives the buyer an exclusive period in which to decide whether to exercise the option. If the buyer does not proceed, HDB states that the seller must wait for the option to expire before granting another OTP.

This makes the pre-OTP review important. A headline offer may be attractive, but the seller should also understand the buyer’s readiness, proposed transaction timeline, likely net proceeds and how the sale connects with the next housing move.

Current HDB process

A seller must have a valid Intent to Sell for at least seven days before granting an OTP. HDB also requires the buyer to have a valid HFE letter before obtaining the OTP. Sellers and buyers must use the prescribed HDB OTP; other agreements or supplementary agreements relating to the resale are not valid under the Housing and Development Act.

After the buyer exercises the OTP, either party may submit its portion of the resale application first. The second party must submit its portion and supporting documents within seven calendar days. The parties must also follow the timeframe agreed under Clause 12 of the OTP.

HDB states that resale completion is generally about eight weeks from its acceptance of the complete resale application. The date in the acceptance letter is the earliest possible completion date, not a guaranteed marketing-to-completion duration.

Who is affected

This checklist is for HDB flat owners who have registered an Intent to Sell and are considering whether to grant an OTP to a resale buyer.

It is particularly relevant when the seller intends to use the proceeds or CPF refund for the next home, needs a particular submission or completion timeline, is considering a temporary extension of stay, has co-owners or unusual supporting documents, or is comparing offers with different buyer-readiness or timing conditions.

Who is not affected

This is not the sale process for private residential, commercial or industrial property. Those transactions use different documents and may involve different legal, tax, financing and completion requirements.

It is also not a buyer’s financing guide. Buyers should review the HFE, bank IPA, Letter of Offer and Request for Value requirements that apply to their situation.

This checklist does not determine whether a particular seller or buyer is eligible, whether a contract is enforceable or how a dispute should be resolved. Those questions require HDB or appropriate professional advice.

What remains unchanged

• The seller and buyer must mutually agree on the resale price.
• A valid Intent to Sell does not guarantee that HDB will approve the eventual transaction.
• The buyer must satisfy the applicable HDB eligibility and financing requirements.
• Gross sale price is not the same as cash proceeds after the outstanding loan, CPF refund and other applicable amounts are accounted for.
• Marketing activity does not guarantee a sale price or completion outcome.
• A temporary extension of stay requires the buyer’s agreement and HDB’s applicable conditions.
• The actual OTP and current instructions in My Flat Dashboard control the transaction.

Planning considerations

1. Confirm that the Intent to Sell is ready

Check My Flat Dashboard for the Intent to Sell validity and the date from which an OTP may be granted. The Intent to Sell also provides information about sale eligibility, applicable block quotas, upgrading matters and nearby transactions.

Do not rely on an old screenshot or earlier assessment if circumstances have changed. Review the current dashboard before committing.

2. Check the buyer’s readiness

HDB requires a buyer to have a valid HFE letter before obtaining an OTP. Ask the buyer or appointed salesperson to confirm that this step is complete.

An HFE letter does not guarantee that every financing or transaction condition will be satisfied. If the buyer is using bank financing, the buyer must complete the applicable Letter of Offer steps before exercising the OTP. The seller need not assess the buyer’s loan, but should understand whether the proposed timeline appears workable.

3. Agree on price and deposit clearly

Record the mutually agreed resale price in the prescribed OTP. HDB allows the Option Fee to be negotiated from S$1 to S$1,000. The Option Exercise Fee is also negotiated, but both fees together cannot exceed S$5,000.

HDB encourages digital payment modes to provide independent proof of payment. Keep complete records of the agreed amounts and receipts.

The buyer’s Request for Value comes after the OTP is granted. A seller should therefore use relevant transaction evidence when considering the price rather than assuming the agreed amount will necessarily be supported for CPF and financing purposes.

4. Estimate the seller’s net position

Before accepting an offer, review the outstanding housing loan, estimated CPF refund with accrued interest, selling expenses and amounts owing to HDB, IRAS or the town council where applicable.

The property sale proceeds calculator can provide an initial illustration, while the CPF refund guide explains the seller-side CPF issue. Confirm the actual figures using official records.

5. Agree on the application timeline

Clause 12 of the OTP records the timeframe within which the parties intend to submit their resale applications. HDB says that changing this contractual timeframe requires mutual agreement.

Once the first party submits its portion, the second party must submit its portion and all required documents within seven calendar days. If the required submissions are not made in time, HDB may cancel the application without refunding the administrative fees.

6. Discuss any extension before granting the OTP

If a seller has committed to buy a completed property in Singapore and needs more time to move, HDB may allow a temporary extension of stay for up to three months, subject to the buyer’s agreement and the prevailing conditions.

The arrangement should be discussed during negotiation and declared in both parties’ resale applications. The buyer becomes the legal owner at completion and bears ownership costs during the extension. Both parties should understand the responsibilities before agreeing.

7. Connect the sale with the next housing plan

Work backwards from the likely completion window. Consider when cash proceeds and CPF refunds may become available, where the household will stay, and whether another purchase depends on the sale.

The HDB selling guide covers the broader journey. Owners moving to another property can also review selling an HDB before buying a condo.
