Key Takeaways
- • Apply for the HFE letter via Singpass on the HDB Flat Portal before viewing flats it tells you your exact eligibility, grant entitlement, and maximum loan amount.
- • The Option to Purchase (OTP) requires a 1% option fee upfront; you then have up to 21 days to exercise it with a further 4% exercise fee.
- • According to HDB, both buyer and seller must independently submit their portions of the resale application on the HDB Flat Portal within 7 days of each other.
- • First-timer families can receive grants totalling up to $120k (EHG) on top of other housing grants but only for income-eligible buyers purchasing a resale flat.
- • Cash Over Valuation (COV) the amount you pay above HDB's assessed value must be paid fully in cash. Budget for this separately from your downpayment.
Buying an HDB resale flat is the most common property transaction in Singapore, yet many buyers start their search without completing the critical first step: obtaining the HFE letter. This guide walks through the full process in chronological order, the way I walk buyers through it in practice.
What is the HFE Letter, and Why Does It Come First?
The HDB Flat Eligibility (HFE) letter is an official document from HDB confirming your eligibility to purchase an HDB flat, the grants you qualify for, and the maximum HDB Concessionary Loan amount available to you (if applicable). According to HDB, you must have a valid HFE letter before an OTP can be granted by a seller.
Apply via Singpass on the HDB Flat Portal (flat.hdb.gov.sg). The application process typically takes 2 to 4 weeks. You will need to provide income details, citizenship status, current property ownership, and marital status. The HFE letter is valid for 9 months.
What the HFE letter tells you:
- Whether you are eligible to buy an HDB resale flat at all (citizenship and family nucleus requirements).
- Your CPF Housing Grant eligibility Enhanced Housing Grant (EHG), Proximity Housing Grant (PHG), and CPF Housing Grant for Families (CHG).
- Whether you qualify for an HDB Concessionary Loan (at 2.6% fixed) or must use a bank loan.
- The maximum loan amount from HDB (if applicable).

How Does the OTP Work for HDB Resale?
The Option to Purchase (OTP) is the legally binding contract between buyer and seller in the HDB resale market. It works as follows:
According to HDB, the OTP cannot be extended beyond 21 days. If the option lapses without exercise, the transaction falls through and the buyer loses the option fee.
Co-buyer rules
All persons listed on the OTP must also be listed on the HFE letter. You cannot add or remove co-buyers between the OTP and completion without withdrawing and re-applying. Get your co-buyer situation settled before the OTP is granted.
What Grants Can You Get When Buying HDB Resale?
Resale flats are eligible for more grant types than BTO flats in many cases. The three key grants in 2026:
Enhanced Housing Grant (EHG) up to $120,000
Income-tested grant for first-timer families purchasing a resale flat. Applicable only if at least one buyer has worked continuously for 12 months prior to application. Income ceiling: $9,000/mth for singles, $9,000/mth household income for families (with varying caps depending on flat type and household income). The EHG amount is tiered based on income the lower your income, the higher the grant.
CPF Housing Grant for Families (CHG) up to $80,000
For first-timer families purchasing a resale flat. Up to $80,000 if both buyers are first-timers purchasing a 4-room or smaller flat; up to $50,000 for a 5-room or larger flat. If one buyer is a second-timer, the grant is halved.
Proximity Housing Grant (PHG) up to $50,000
According to CPF Board, the PHG is available regardless of first-timer status. It rewards buyers who purchase a resale flat within 4km of their parents' or children's home, or to live with them in the same flat. Up to $30,000 if you buy within 4km; up to $20,000 additional if you buy to live with parents or children in the same flat (combined max $50,000).
What Is Cash Over Valuation (COV) and How Do You Handle It?
When you agree to buy a resale flat at a price higher than HDB's assessed valuation, the difference is called Cash Over Valuation (COV). COV must be paid entirely in cash it cannot be covered by your CPF or your bank loan.
For example: if the agreed price is $650,000 and HDB's valuation comes in at $610,000, the COV is $40,000. This $40,000 must come from your own cash savings, on top of your regular downpayment.
How to handle COV in your negotiation:
- Check recent transaction prices for comparable flats in the same block and vicinity on the HDB Resale Flat Prices portal (data.gov.sg / HDB portal) before making an offer.
- COV negotiation is entirely between buyer and seller HDB does not intervene in price negotiations.
- If a flat has a very high COV expectation, model the total cash outflow carefully before deciding whether to proceed.
- Get the valuation report from your bank early (usually within 5 days of appointing a valuer). If the gap is larger than expected, you have time to renegotiate or walk away before exercising the OTP.
Winfred's Take
Most buyers focus on the flat price and forget that COV can add $30,000 to $60,000 in additional cash they weren't expecting. Always get the HFE letter before you start viewing so you walk into every negotiation knowing your precise CPF usage, grant entitlement, loan ceiling, and how much cash you actually have to work with. Buyers who skip this step end up either losing their 1% option fee when financing doesn't work out, or overstretching on COV because they hadn't done the full cash-out calculation.

Frequently Asked Questions
Can I start viewing flats before my HFE letter is ready?
You can attend viewings, but you should not make any offers or pay any option fees until your HFE letter is in hand. Without it, you don't know your actual budget and sellers who receive an offer without an HFE letter are unlikely to take it seriously.
What happens if HDB rejects my resale application?
HDB rejections are rare and typically involve eligibility issues (ownership of another property, citizenship requirements not met, family nucleus not satisfied). If rejected, the transaction is unwound the buyer's option fees may be forfeited depending on the reason. Always verify eligibility via the HFE letter process before signing any OTP.
Can I use both CPF and cash for the downpayment?
Yes. If you are using a bank loan, the minimum downpayment is 25% of the purchase price 5% must be in cash and the remaining 20% can be CPF OA, cash, or a combination. If you are using an HDB loan, the minimum downpayment is 20%, which can be fully paid using CPF OA.
Is there a minimum occupation period (MOP) for resale flats I buy?
Yes. You must occupy the HDB resale flat you purchase for a minimum of 5 years (MOP) before you can sell it on the resale market or rent it out entirely. You can, however, rent out individual bedrooms (subject to HDB approval) during the MOP.
Do I need a property agent to buy a resale flat?
It is not mandatory, but HDB's resale portal process and grant applications involve multiple overlapping deadlines. An experienced agent ensures your HFE letter, AIP, OTP timeline, and portal submission are synchronised and can negotiate price and COV on your behalf using real transaction data. The cost of a buyer's agent is typically 1% of the purchase price.
