What Is the HDB Flat Portal?
The HDB Flat Portal (flat.gov.sg) is HDB’s centralised digital platform that consolidated several previously separate applications into one interface. The portal handles:
- HFE (HDB Flat Eligibility) letter applications
- BTO flat applications and ballot queue checks
- Resale flat transactions (intent to buy/sell, valuation request, resale application)
- CPF housing withdrawal enquiries
- Flat ownership and eligibility checks
Agents acting for clients in HDB transactions must be familiar with the portal because most steps that previously required an HDB branch visit are now completed online. Delays in client transactions are often caused by incomplete portal submissions or missing SingPass-linked documents.
Step 1: HFE Letter — Before Any Flat Booking
The Flat Eligibility (HFE) letter replaced the older HDB Loan Eligibility (HLE) letter and In-Principle Approval (IPA) process. Clients must obtain an HFE letter before:
- Booking a BTO flat
- Registering Intent to Buy a resale flat
The HFE letter covers in one document:
- Eligibility to buy an HDB flat (citizenship, ownership history, income ceiling)
- HDB Concessionary Loan eligibility and maximum loan quantum
- CPF housing grants the household qualifies for (EHG, Family Grant, PHG)
Agents should advise clients to apply for the HFE letter well in advance of any BTO launch or resale OTP signing. The HFE letter is valid for 6 months from issue date. If it expires before the transaction completes, the client must apply for a new one.
HFE Letter Application: Documents and MyInfo
The HFE application is done through the Flat Portal using SingPass MyInfo. The portal pre-populates income data from IRAS (based on the prior Notice of Assessment) and CPF contribution history. Agents should prepare clients for the following:
- Income data lag: MyInfo pulls prior-year IRAS income data. Clients whose income changed significantly in the current year (e.g., recently employed, recently self-employed) may need to provide manual income documentation for the HDB assessment to reflect their current income accurately.
- Co-applicant SingPass access: All co-applicants must log in individually to consent to MyInfo data sharing. This includes the spouse or fiancé/fiancée co-applying for the flat.
- Foreign spouses: Non-Singapore Citizens/PRs who do not have a SingPass account cannot use MyInfo. Their income and identity documents must be submitted manually through HDB’s offline channels. Agents should flag this early to avoid delays.
- Processing time: HFE letters are typically issued within a few working days for straightforward applications. Complex cases (self-employed, variable income, foreign co-applicants) may take longer.
BTO Application Workflow Through the Portal
For BTO flat applications, the Flat Portal workflow proceeds as follows:
- Application window: During a BTO launch exercise (typically quarterly), clients apply through the Flat Portal during the specified application window (usually 1 week). Clients select their preferred project, flat type, and indicate any applicable priority schemes (PPS, MCPS, TCPS, SPS, MGPS).
- Ballot queue result: After the application window closes, HDB releases ballot queue numbers via the Flat Portal. Clients can log in to check their queue number. A lower queue number means earlier selection access.
- Flat selection appointment: Clients with sufficient queue numbers are invited for a flat selection appointment. The invitation is sent through the Flat Portal and by letter. Agents should confirm the appointment date with clients and prepare them for the selection process.
- Agreement for Lease (AFL) signing: After selecting a flat, the client signs the Agreement for Lease through the portal (or at HDB). The Stage 1 downpayment is collected at this point.
Resale Flat Workflow Through the Portal
For HDB resale transactions, the Flat Portal manages both the buyer and seller sides. The key steps:
- Seller: Register Intent to Sell — Sellers must register their intent to sell through the Flat Portal before granting an OTP. This step checks MOP compliance, outstanding loans, and ownership eligibility to sell. Registration is valid for 12 months.
- Buyer: Register Intent to Buy — Buyers must register their intent to buy (and have a valid HFE letter) before receiving an OTP from the seller. This confirms the buyer’s eligibility and applies the applicable grants.
- Option to Purchase (OTP): Once both intent registrations are complete, the seller grants the OTP. The buyer has 21 days from the OTP date to exercise it (or the extended period if agreed).
- Resale application submission: After the OTP is exercised, both buyer and seller submit their resale application through the Flat Portal — buyer and seller must each submit their own portion. HDB requires both submissions within a specified window.
- HDB approval and completion: HDB processes the resale application, issues the approval letter, and schedules the resale completion appointment. The completion timeline is typically 8 weeks from submission for straightforward cases.
CPF Housing Withdrawal Through the Portal
CPF withdrawal for HDB flat purchases is also managed through the Flat Portal in coordination with CPF Board. When the client has an approved HFE letter and completes a flat booking, the portal links the transaction to the CPF withdrawal request. Key points for agents:
- CPF withdrawal is processed by CPF Board after the resale application is approved or the AFL is signed. The client does not separately apply to CPF — the Flat Portal triggers the CPF deduction.
- The CPF withdrawal amount is limited to the Valuation Limit (the lower of purchase price or valuation) plus applicable housing grants credited to CPF OA.
- Clients should maintain sufficient CPF OA balance to cover their downpayment at each stage (especially relevant for the Staggered Downpayment Scheme).
Common Portal Errors and How Agents Can Help
Agents should be aware of the most common causes of portal delays:
- Expired HFE letter: The transaction cannot proceed without a valid HFE letter. If the letter expires, advise the client to reapply immediately. The reapplication process is the same as the initial application.
- Missing co-applicant consent: If a co-applicant has not completed their MyInfo consent, the HFE application will stall. Ensure all co-applicants complete their login steps before the application is submitted.
- Intent to Sell not registered: Sellers who have not registered their intent to sell before granting an OTP may have the OTP invalidated by HDB. Confirm registration before any OTP is issued.
- Resale application mismatch: If the buyer and seller portal submissions contain inconsistent information (price, included items, completion date), HDB will flag the discrepancy. Agents should ensure all transaction terms are agreed in writing before portal submission.
Frequently Asked Questions
Q: Can an agent submit the HFE letter application on behalf of the client?
A: No. The HFE application requires each applicant to log in individually using their own SingPass to consent to MyInfo data sharing. Agents cannot submit on behalf of clients and must not handle clients' SingPass credentials. Agents can guide clients through what to do in the portal and review the output together, but the client must perform all portal steps themselves.
Q: How long does the HDB resale portal process take from submission to completion?
A: For straightforward HDB resale cases, the portal process from submission to HDB approval typically takes 8 weeks. Complex cases (foreign co-applicants, outstanding CPF or HDB loans, disputes on flat condition) may take longer. Agents should set client expectations at 8–12 weeks from OTP exercise to key handover.
Q: What happens if the seller registers Intent to Sell but then decides not to sell?
A: The Intent to Sell registration does not obligate the seller to sell. It is an eligibility check, not a binding commitment. If the seller changes their mind after registration, there is no penalty from HDB — however, if an OTP has already been granted and the seller defaults, standard contractual remedies (forfeiture of option fee, damages) apply.
Q: Can buyers check their BTO ballot queue number through the portal before the flat selection appointment?
A: Yes. After the ballot results are released, applicants can log into the Flat Portal with their SingPass to check their queue number and estimated selection window. Agents should remind clients to check their queue number promptly, as flat selection invitations may be sent on short notice once queues begin moving.
