How does buying a resale HDB flat actually work?

📌 Quick Answer 

 Start by getting your HFE letter, which can take up to a month once all the required documents are submitted. After a seller grants you the OTP, you have 21 calendar days to settle the valuation and financing before deciding whether to proceed. Once both parties submit the resale application, HDB may take up to 28 working days to accept it, with completion usually about eight weeks later. And don’t budget for the downpayment alone: you will also need to account for the cash deposit, valuation, application, stamp duty and legal fees. But agreeing on the price is only the beginning. Before the keys are handed over, you still need to secure the OTP, confirm the valuation and financing, submit the resale application and complete the legal transfer. None of these stages is especially complicated on its own. The tricky part is knowing what must happen first, which deadlines you cannot miss and how much cash or CPF savings you will need along the way. 

Here is how the HDB resale process works, from initial planning to key collection. 

1. Get your eligibility and financing sorted 

 Before you seriously search for a resale flat, apply for an HFE letter through the HDB Flat Portal. 

The letter confirms: 

• Whether you are eligible to buy an HDB flat 

• Which CPF housing grants you may receive 

• Whether you qualify for an HDB housing loan 

• The amount of HDB housing loan you may be offered 

HDB may take up to a month to process the application after receiving all the required information and documents. Processing can take longer during busy periods, so this is not something to leave until you have found a flat you love. 

Your HFE letter is valid for nine months from its date of issue. It must be valid when the seller grants you an OTP and again when you submit your resale application. 

The applicants and occupiers named in the resale application must also match those in the HFE letter. If your household composition, marital status, citizenship or property ownership changes before you submit the resale application, check with HDB early. Depending on the change, you may need to cancel the existing HFE letter and apply for a new one. 

If you are considering a bank loan, you can request an In-Principle Approval (IPA) from a participating financial institution at the same time as your HFE application. This lets you compare your HDB and bank financing options before committing to either. 

 2. Find a flat and agree on the price 

Once your HFE letter is in hand, you can search for a flat within your budget. This is also where it pays to look past the asking price: check recent transacted prices for comparable units in the same block or estate, since that’s a better anchor for negotiation than the seller’s listing figure alone. 

When you and the seller agree on a price, the seller grants you an Option to Purchase. The seller must have had an Intent to Sell registered for at least seven days before they can grant it. 

You’ll pay the seller an Option Fee at this point, negotiated between $1 and $1,000. You then have 21 calendar days to decide whether to exercise the option. If you do, you pay an Option Exercise Fee, and the two fees combined are capped at $5,000 in total. 

Suppose you pay the maximum $1,000 Option Fee. Because the combined cap is $5,000, your Option Exercise Fee on exercising can be at most $4,000, for a $5,000 total deposit regardless of the flat’s price. If you’re using CPF savings or a housing loan, you (or your agent) must submit a Request for Value to HDB by the next working day after receiving the OTP. If you’re paying entirely in cash, this step doesn’t apply. 

If you’re taking an HDB loan, your HFE letter’s loan outcome carries through automatically. If you’re taking a bank loan instead, you’ll need a valid Letter of Offer before you exercise the OTP. If you requested an IPA earlier, this is the point to convert it. If the flat is bought above its valuation, that gap, the cash-over-valuation, must be paid entirely in cash, separately from your loan and CPF. 

3. Submit your resale application 

 After you exercise the OTP, you and the seller must each submit your portion of the resale application through My Flat Dashboard. Both submissions must be made within the period agreed in the OTP and within seven days of each other. 

HDB considers the application complete only after receiving both portions and the required supporting documents. If everything is in order, HDB will verify both parties’ eligibility and accept the application within 28 working days. 

About three weeks after acceptance, HDB will prepare the resale documents for both parties to endorse. You and the seller must then endorse the documents and pay the applicable fees, including legal fees and Buyer’s Stamp Duty. 

If the seller needs a temporary extension of stay, both parties must declare the arrangement when submitting their respective portions of the resale application. It cannot be added informally after the application has been submitted.4.  Prepare for completion and key collection 

Once documents are endorsed and fees paid, HDB grants approval for the transaction. Completion is scheduled for about 8 weeks from the date HDB accepted the resale application, and you’ll be notified of the appointment by SMS. 

At the completion appointment itself, ownership formally transfers to you: your loan and CPF funds are disbursed, the  You must pay the balance of the purchase price and any outstanding fees before or during the completion appointment when you receive the keys.  Before the appointment, inspect the flat to confirm that the seller has moved out and that vacant possession will be delivered. You can also check that any fittings or appliances included in the agreed inventory remain in the flat. 

What if the Seller Needs More Time to Move Out? 

A seller may request a temporary extension of stay for up to three months after completion, but it is not automatically available simply because they need more moving time. 

Among other conditions, the seller must have committed to buying a completed residential property in Singapore and must not be renting out the whole resale flat. The buyer must agree to the arrangement, and both parties must declare it when submitting their portions of the resale application. 

The resale transaction still completes on schedule, which means the buyer becomes the legal owner while the seller remains temporarily in the flat. The $20 administrative fee for the extension is payable by the buyer. During the extension, the buyer is responsible for ownership costs such as: 

• Housing-loan instalments 

• Service and conservancy charges 

• Property tax at the non-owner-occupied rate 

The buyer’s Minimum Occupation Period begins only after the temporary extension ends. Because this is a private arrangement, both parties should discuss the practical and financial terms carefully before agreeing to it. What does buying an HDB resale flat cost beyond the price? 

The downpayment is not the only amount you need to plan for. Depending on your purchase, the additional costs may include: 

• Option Fee and Option Exercise Fee of up to $5,000 in total 

• $120 Request for Value fee 

• Resale application fee of $40 for a one- or two-room flat, or $80 for a larger flat 

• Buyer’s Stamp Duty 

• Legal, conveyancing and registration fees 

• Cash-over-valuation, if applicable 

• Private solicitor’s fees if you use a bank loan 

• Agent commission if you engage a property agent 

• Additional Buyer’s Stamp Duty, if applicable 

Suppose you are buying a $500,000 resale flat. Buyer’s Stamp Duty is calculated progressively: 

• 1% on the first $180,000: $1,800 

• 2% on the next $180,000: $3,600 

• 3% on the remaining $140,000: $4,200 

That brings the total Buyer’s Stamp Duty to $9,600. 

CPF Ordinary Account savings may be used for eligible stamp duty and legal fees. However, because an HDB resale flat is a completed property, you may need to pay the stamp duty in cash first and receive the CPF reimbursement when the purchase is completed. The Option Fee, Option Exercise Fee and any COV must be paid in cash. How the Process can differ by buyer 

If you’re a second-timer who previously bought a subsidised flat, check early whether a resale levy applies to your specific move; it doesn’t change any of the steps above, but it does change how much cash you need on hand by completion. 

If you’re buying with a bank loan rather than an HDB loan, the timeline has one extra dependency: your Letter of Offer needs to be valid before you exercise the OTP, on top of your HFE letter being valid at both checkpoints. Applying for your IPA at the same time as your HFE letter keeps these running in parallel instead of one holding up the other. 

And if you’re buying with family, most of the process is identical, but the household arrangement on your HFE letter, who’s listed as an applicant, co-applicant, or occupier, needs to be settled before you apply, since changing it later can mean reapplying rather than simply amending a detail. 

Get the HFE letter before you get attached to a flat 

It is tempting to begin with listings, viewings and neighbourhood comparisons. But the most useful first step is getting your HFE letter and understanding what you can comfortably afford. Once that is sorted, the rest of the process becomes much easier to manage. You will know your financing options, understand your deadlines and be less likely to lose a flat because an important document or approval is missing. 

The resale process involves several stages, but they all lead to one very satisfying final step: collecting the keys to a home that is officially yours.
