Overview: The HDB Resale Portal
The HDB Resale Portal (resale.hdb.gov.sg) is the mandatory platform for all HDB resale flat transactions in Singapore. It handles:
- Intent to Sell and Intent to Buy registration
- Resale application submission (joint buyer-seller submission)
- Document uploads and verification
- HDB appointment scheduling
- Disbursement instructions (CPF, HDB loan, cash)
All registered CEA agents can transact via the portal using their Singpass. Agents submit on behalf of their clients with client authorisation — clients must still log in separately to approve and verify key steps using their own Singpass.
Stage 1: Intent to Sell (Seller)
Before granting an OTP to a buyer, the seller (or the seller's agent on their behalf) must register an Intent to Sell on the HDB Resale Portal.
What Intent to Sell Does
- Checks if the seller is eligible to sell (MOP status, outstanding charges, flat type restrictions)
- Generates a HDB Ethnic Integration Policy (EIP) and SPR Quota eligibility check — confirming which buyer ethnicities and PR status are eligible for the specific block and neighbourhood
- Triggers a check on any outstanding HDB upgrading levy or service and conservancy charges
- The system generates an eligibility result that is valid for 7 days
Agent's Role at Intent to Sell Stage
The seller's agent should:
- Assist the seller to log in to the portal and register the Intent to Sell before marketing the property
- Review the EIP/SPR Quota result — if the block's quota for certain ethnicities or PRs is filled, this restricts the eligible buyer pool and must be disclosed to prospective buyers
- Note the 7-day validity — if the OTP is granted after the Intent to Sell expires, a fresh registration is required
Stage 2: Intent to Buy (Buyer)
The buyer must register an Intent to Buy on the HDB Resale Portal before exercising the OTP. The Intent to Buy:
- Checks the buyer's eligibility to purchase an HDB resale flat (family nucleus, citizenship/PR status, ownership of other properties)
- Allows the buyer to apply for the HDB Loan Eligibility (HLE) letter if they intend to use an HDB concessionary loan — the HLE is required before OTP exercise for HDB loan buyers
- Provides the buyer with an estimate of CPF grants they may be eligible for (Enhanced Housing Grant, Family Grant, Proximity Housing Grant)
Agent's Role at Intent to Buy Stage
The buyer's agent should:
- Ensure the buyer completes Intent to Buy before the seller grants the OTP — this establishes the buyer's eligibility and informs the decision to proceed
- If the buyer needs an HDB loan, ensure the HLE letter is obtained before OTP exercise (not during the exercise period)
- Review the CPF grant estimates with the buyer — grants affect the buyer's net cash outlay and CPF usage planning
Stage 3: OTP Grant and Exercise
After Intent to Sell and Intent to Buy are registered, the seller grants the OTP. Standard HDB resale OTP:
- Option fee: S$1 to S$1,000 (capped by HDB at S$1,000 for resale flats)
- Option period: 21 calendar days (fixed — cannot be extended)
- Exercise money: S$4,999 maximum (combined with option fee, total cannot exceed S$5,000 for HDB resale)
The buyer exercises the OTP by signing and returning it to the seller with the exercise money within the 21-day option period.
Stage 4: Joint Resale Application Submission
After OTP exercise, both buyer and seller must jointly submit the resale application via the HDB Resale Portal within 7 days of OTP exercise. Both parties (or their agents on their behalf) must submit their respective portions within the same 7-day window.
Seller's Submission
Documents and information required from the seller side:
- Seller's particulars and NRIC details
- Agreed resale price
- Confirmation of resale conditions (MOP, HDB upgrading levy)
- CPF charge settlement instructions (outstanding CPF principal + accrued interest to be refunded to seller's CPF OA upon completion)
- Outstanding HDB loan redemption statement (if any)
Buyer's Submission
Documents and information required from the buyer side:
- Buyer's particulars and family nucleus details
- Financing mode (HDB loan or bank loan or cash)
- CPF usage amount and CPF grant applications
- Solicitor details (if using a law firm for conveyancing)
- HLE letter (if HDB loan) or bank's Letter of Offer (if bank loan)
Stage 5: HDB Processing and Valuation
After joint submission, HDB processes the application. Key steps during this period:
- HDB valuation — HDB will instruct a valuer to value the flat. Cash Over Valuation (COV) cannot be financed by HDB loan or CPF — it must be paid in cash by the buyer
- Document verification — HDB verifies all documents and eligibility conditions
- CPF grant processing — CPF Board processes any applicable housing grants
- HDB appointment scheduling — HDB schedules the resale completion appointment
Processing typically takes 6–8 weeks from submission. Complex cases (those involving CPF accrued interest disputes, overseas sellers, or legal complications) may take longer.
Stage 6: HDB Resale Completion Appointment
The HDB completion appointment is held at HDB Hub or a satellite HDB office. Both buyer and seller (or their solicitors/authorised representatives) attend. At the appointment:
- Seller signs documents confirming transfer of flat ownership
- Buyer pays the balance purchase price (cash portion after CPF and HDB/ bank loan)
- HDB registers the transfer of ownership
- Keys are handed over to the buyer
- Seller's CPF refund (principal + accrued interest) is processed automatically by CPF Board
| Stage | Who Acts | Typical Timeline |
|---|---|---|
| Intent to Sell | Seller (before OTP grant) | Before marketing; valid 7 days |
| Intent to Buy | Buyer (before OTP exercise) | Before OTP exercise; HLE required if HDB loan |
| OTP grant | Seller | Day 0 |
| OTP exercise | Buyer | Within 21 days of grant |
| Joint resale application | Buyer + Seller (jointly) | Within 7 days of OTP exercise |
| HDB processing + valuation | HDB | ~6–8 weeks |
| Completion appointment + keys | Buyer + Seller at HDB | ~8–12 weeks from OTP exercise |
Common Causes of Delay
Agents should watch for these frequent delay triggers:
- Missing documents at joint submission — incomplete submissions extend HDB processing time
- COV disputes — if HDB's valuation is lower than the agreed price, the buyer must confirm they can pay the COV in cash before HDB proceeds
- Outstanding HDB upgrading levy — must be resolved before completion
- Overseas seller — a seller residing overseas needs to arrange a power of attorney for HDB completion; this adds lead time
- CPF accrued interest shortfall — if sale proceeds are insufficient to fully refund CPF (principal + accrued interest), CPF Board must approve the shortfall before HDB releases the completion date
Frequently Asked Questions
Q: Can the agent submit the resale application without the client being present?
A: Yes — the agent can submit the seller's or buyer's portion of the resale application on their behalf through the portal. However, the client must separately log in to the portal with their Singpass to verify and approve certain steps, including the final resale application. The client cannot completely delegate all portal actions to the agent.
Q: What if the buyer changes financing mode after the application is submitted (e.g., switches from HDB loan to bank loan)?
A: A change in financing mode after the resale application has been submitted requires the buyer to update the application on the portal. If the change is significant (e.g., HDB loan to bank loan), the buyer may need to withdraw the HLE letter and submit a bank's letter of offer instead. This can delay processing. Agents should confirm financing mode before submission.
Q: Does the seller's agent need to be present at the HDB completion appointment?
A: Agents do not need to attend the HDB completion appointment — it is primarily a legal completion between buyer, seller (or their solicitors), and HDB. However, some agents attend as a client service, particularly to assist with any last-minute issues. If either party has appointed a solicitor, the solicitor handles the appointment.
Q: What happens if the joint resale application is not submitted within 7 days?
A: HDB will reject the application. The parties will need to restart — a new OTP must be granted and exercised. The original OTP exercise does not remain valid. This means a fresh 21-day OTP period, re-registration of Intent to Sell/Buy if the validity has expired, and the associated delay costs. Agents must track the 7-day deadline carefully.
Q: Can the seller find a new buyer while the resale application is being processed?
A: No. Once the resale application is submitted and accepted by HDB, the seller is committed to selling to that specific buyer. The seller cannot market the flat or accept another offer while the application is in process. Withdrawing the application after submission may attract administrative consequences and requires both buyer and seller to agree.
