The HDB resale buying process starts with your HDB Flat Eligibility (HFE) letter, followed by choosing a flat, obtaining an Option to Purchase (OTP), checking financing and submitting the resale application. Completion comes later, after HDB accepts and processes the application.
Keep a calendar for the transaction. Eligibility, valuation, financing and payment checks need to happen in the correct order, even when you have already agreed on the price.
- Obtain your HFE letter and plan financing.
- Choose an eligible flat and agree on the terms.
- Obtain the prescribed OTP.
- Request the value where required and confirm funding.
- Exercise the OTP if proceeding.
- Submit the resale application and complete HDB’s instructions.
- Complete the purchase and arrange possession.
1. Obtain your HFE letter before getting an OTP
The HFE letter assesses your eligibility to buy a flat, receive CPF housing grants and obtain an HDB housing loan, including the assessed amounts. It replaces the old HDB Loan Eligibility (HLE) approach for current applications.
You need a valid HFE letter before obtaining an OTP and when submitting your resale application. Apply early through HDB’s services and provide the required information. Check the letter’s validity and any changes in your household circumstances before proceeding.
If using a bank loan, obtain a financing assessment separately. Set your budget using the funds and loan available to you, not the largest grant or loan advertised for other buyers.
2. Shortlist flats and check the full budget
Check eligibility for the particular flat, including the Ethnic Integration Policy and applicable Singapore Permanent Resident quota. Review its classification, occupation conditions and remaining lease.
Allow for the downpayment, applicable duties, legal and administrative fees, renovation, moving and a reserve. Confirm how much CPF you can use and which payments require cash.
Inspect the actual home and clarify alterations, condition, included items and possession arrangements. Our HDB resale viewing checklist covers this stage in detail.
3. Agree on price and obtain the prescribed OTP
Use HDB’s prescribed OTP. Agree on the price and important terms before paying. Check that the seller has completed the required Intent to Sell waiting period and is eligible to sell.
The option fee cannot exceed $1,000. If you proceed, the option fee and option exercise fee together cannot exceed $5,000. These payments form part of the purchase price; they are not the entire downpayment or transaction budget.
The option period is 21 calendar days after the Option Date, including weekends and public holidays. Record the exact expiry shown in the documents. Do not assume it can be extended to accommodate an unfinished loan application.
4. Request the value and confirm your funding
If buying with CPF savings and/or a housing loan, submit the Request for Value by the next working day after obtaining the OTP. Follow HDB’s submission instructions and provide the required documents.
The agreed price may differ from the value used for financing and CPF purposes. Any cash-over-valuation amount needs cash funding. Check the actual valuation outcome and available funds before exercising.
If taking a bank loan, you must have a valid Letter of Offer when exercising the OTP. An earlier indicative assessment is not a substitute. Confirm the loan terms, required acceptance steps and payment arrangements with your bank.
HDB’s official buying overview explains the sequence. Resolve any funding shortfall before the contractual deadline.
5. Exercise only when ready to proceed
Review the documents and confirm that the price, financing, cash requirements and agreed terms work for you. Follow the prescribed exercise procedure and pay the agreed exercise fee within the option period.
If you allow the OTP to expire without exercising, the option fee is forfeited under the prescribed terms. Exercising creates a binding sale and purchase contract. Do not assume you can later withdraw simply by losing the deposit.
Get advice from your conveyancer on unresolved contractual questions before exercising.
6. Submit both portions of the resale application
Buyer and seller submit their respective portions within the agreed submission period. Once one party submits, the other must submit within seven calendar days. Coordinate this in advance and prepare supporting documents.
Submission is different from HDB’s acceptance. HDB checks the application and may require additional information. Keep contact details current and respond promptly to requests.
Do not book irreversible renovation or moving arrangements based only on the date you submit.
7. Endorse documents and make the required payments
Follow the notifications in the HDB Flat Portal. Review the financial plan and documents carefully, endorse within the stated deadline and arrange the required payments.
HDB’s current guidance provides a six-calendar-day endorsement window after notification. Use the actual instructions for your application; late endorsement or payment can delay the transaction.
Coordinate CPF applications, bank funds and conveyancing arrangements where applicable. Confirm the balance payable and duty arrangements rather than assuming that every cost is covered by your loan.
8. Prepare for completion and possession
HDB’s published guide indicates completion is about eight weeks from acceptance of the resale application. This is not an eight-week guarantee from your first viewing or OTP date. Your application and any approved arrangements determine the actual schedule.
Before completion, arrange the inspection required of buyers and check the agreed condition and included items. HDB’s own inspection is not a comprehensive condition survey. Raise unresolved issues through the appropriate parties.
Confirm when you receive possession. A seller’s temporary extension of stay requires the applicable HDB approval and means moving in can occur after legal completion. Understand the costs and responsibilities before agreeing.
After possession, arrange utilities, insurance, renovation approvals and moving. Keep the purchase documents and payment records.
Common mistakes to avoid
- Obtaining an OTP before having a valid HFE letter.
- Missing the next-working-day Request for Value deadline.
- Exercising before confirming the required bank Letter of Offer.
- Assuming the option payments cover the full downpayment.
- Confusing submission, acceptance, completion and possession dates.
- Relying on a seller extension that has not been properly arranged.
Keep the official HDB resale terms alongside your transaction calendar. Your agent, lender and conveyancer should help you resolve questions before the relevant deadline.
