HFE LETTER

Apply for Your HDB Flat Eligibility (HFE) Letter

Before you start flat-hunting, you must apply for an HDB Flat Eligibility (HFE) Letter via the HDB Flat Portal using Singpass. This letter confirms your eligibility to buy an HDB resale flat, the CPF Housing Grants you qualify for, and the HDB housing loan amount you can take (if applicable).

  • Apply via the HDB Flat Portal with all applicants logged in using Singpass
  • HDB will assess your eligibility based on your household composition, income, and existing property ownership
  • The HFE Letter is valid for 9 months from the date of issue
  • You must have a valid HFE Letter before exercising an OTP
💡 WHY THIS MATTERS

The HFE Letter tells you exactly how much CPF Housing Grant you qualify for and your maximum HDB loan amount. This is essential for budgeting before you start viewing flats — knowing your ceiling prevents disappointment later.

⚠️ PLAN AHEAD — HFE VALIDITY

Your HFE Letter must still be valid at the point of submitting the resale application. If you expect your flat search to take several months, apply early. A lapsed HFE Letter means delays — you will need to reapply before proceeding.

CPF Housing Grants for Resale Flats

FLAT SEARCH

Find the Right Flat

With your HFE Letter in hand, you can now actively search for resale flats. Use the HDB Flat Portal's Resale Flat Listing (RFL) service, property portals, or engage a salesperson to help you find options that meet your needs and budget.

  • Browse listings on the HDB Flat Portal (RFL), 99.co, PropertyGuru, or EdgeProp
  • Check recent transacted prices of nearby flats of the same type via HDB's Resale Statistics
  • Factor in the Ethnic Integration Policy (EIP) — not all buyers are eligible for all blocks due to ethnic quota limits
  • Consider proximity to MRT, schools, amenities, and remaining lease when shortlisting
  • Arrange viewings and assess the condition of the flat — factor in renovation costs
💡 PRO TIP FROM DENNIS

Always check the remaining lease of the flat carefully. HDB flats have a 99-year lease — a flat with fewer than 60 years remaining may affect your CPF usage and bank loan eligibility. Older leases also affect resale value down the road.

📍 EIP & SPR QUOTA

Each HDB block has ethnic and SPR quotas. Before making an offer, check whether you are eligible to buy in that specific block. Your salesperson or the HDB Flat Portal can help verify this before you commit.

OPTION TO PURCHASE

Receive & Review the OTP

Once you and the seller have agreed on the resale price, the seller will grant you an Option to Purchase (OTP). This is a legally binding document that gives you the exclusive right to buy the flat at the agreed price during the Option Period.

  • The seller grants you the OTP at the agreed resale price
  • Pay the Option Fee (negotiable, $1 to $1,000) to the seller upon receiving the OTP
  • The OTP is valid for 21 calendar days from the date it is granted
  • Use this time to carefully review the terms and do your due diligence
  • If you decide not to proceed, allow the OTP to expire — you will forfeit the Option Fee
⚠️ OPTION FEE IS NON-REFUNDABLE

If you choose not to exercise the OTP, you will forfeit the Option Fee paid to the seller. Make sure you are committed before accepting the OTP. Total Option Fee + Exercise Fee cannot exceed $5,000.


4
VALUATION

Submit a Request for Value

After receiving the OTP but before exercising it, you should submit a Request for Value (RFV) through the HDB Flat Portal. This requests an official valuation of the flat, which is important if you are using CPF funds or an HDB loan to finance your purchase.

  • Submit the RFV via the HDB Flat Portal after receiving the OTP
  • HDB will appoint a registered valuer to assess the flat's market value
  • CPF funds and HDB loans can only be used up to the lower of the purchase price or valuation
  • If the agreed price exceeds the valuation (Cash-Over-Valuation or COV), the difference must be paid in cash
💰 UNDERSTANDING COV (CASH-OVER-VALUATION)

If you agree to buy at $650,000 but the valuation comes in at $620,000, you must pay the $30,000 difference entirely in cash — CPF cannot cover COV. Always factor in potential COV when budgeting, especially in a hot market.

🏦 BANK LOAN VS HDB LOAN

If you are taking a bank loan instead of an HDB loan, arrange your In-Principle Approval (IPA) from your bank early. Banks have their own valuation process which may differ from HDB's. Your HFE Letter will confirm which financing option you are eligible for.


5
RESALE APPLICATION

Exercise OTP & Submit Resale Application

To proceed with the purchase, you must exercise the OTP within the 21-day Option Period by paying the Option Exercise Fee to the seller. After exercising, both you and the seller must each submit your respective portions of the resale application within 7 calendar days of each other.

  • Exercise the OTP before it expires — pay the Option Exercise Fee to the seller
  • Log in to the HDB Flat Portal and submit your buyer's portion of the resale application
  • Provide all required information — buyer particulars, financial details, grant declarations
  • Pay the administrative fee upon submission
  • Coordinate with the seller to ensure both submissions are within 7 calendar days of each other
⚠️ 7-DAY RULE — DON'T MISS IT

Both buyer and seller must submit their portions of the resale application within 7 calendar days of each other. If either party misses this window, the entire application is cancelled with no refund of fees. Communicate clearly with the seller on submission timing.

📄 DOCUMENTS YOU WILL NEED

NRIC of all buyers and occupiers, HFE Letter, CPF withdrawal details, bank loan letter (if applicable), and any supporting documents for grants claimed. HDB will notify you if additional documents are required.


6
HDB APPROVAL

Await HDB's Approval

After both parties submit the resale application, HDB will review and process it. This typically takes around 28 working days (approximately 40 calendar days). During this period, HDB verifies eligibility, confirms financing, and processes CPF grant disbursements.

  • HDB checks eligibility of all buyers and occupiers listed in the application
  • CPF Board processes any CPF Housing Grants and CPF withdrawal requests
  • Your bank (if bank loan) will complete its own legal and valuation processes
  • HDB will notify you once the application is accepted and the completion appointment is scheduled
📅 WHAT TO DO DURING THIS PERIOD

Start planning your renovation and move-in timeline. Engage a contractor early as popular ones book up quickly. Also arrange for utilities transfer (SP Group) and update your address with relevant agencies after completion.


7
COMPLETION

Resale Completion — Collect Your Keys

The resale completion appointment is typically scheduled about 8 weeks after HDB's acceptance of the application. This is the final step — ownership of the flat is officially transferred to you and you collect your keys.

  • Attend the resale completion appointment at HDB Hub
  • Bring all documents stated in the appointment letter
  • The remaining purchase price is paid — CPF funds are disbursed, bank loan is drawn down, and any cash balance is paid to the seller
  • Collect the keys to your new flat after the appointment
  • Register your new address with relevant government agencies via Singpass
🔑 AFTER COLLECTION OF KEYS

You may begin renovation after collecting the keys. Note that HDB has renovation guidelines — certain works require HDB's prior approval (e.g. hacking of walls, installation of grilles, air-con trunking). Check with HDB or your contractor before commencing work.

📋 CONDITIONS AFTER BUYING

After buying a resale flat, you are subject to the Minimum Occupation Period (MOP) of 5 years before you can sell the flat or rent it out in its entirety. You also cannot own or invest in private residential property during the MOP.
