Every seller asks the same first question: "How much is my flat worth?"
It's the right question, but the answer is layered. "Worth" means at least three different things in a Singapore HDB transaction, and mixing them up is how sellers end up either under-pricing and leaving money on the table, or over-pricing and watching their listing gather dust.
Here's the breakdown.
Valuation, asking price and offer price: what is the difference?
1. Valuation
HDB determines a value through the buyer’s Request for Value after an Option to Purchase (OTP) is granted. HDB decides whether a valuation is required. If needed, HDB appoints a valuer who arranges an inspection; a visit is not automatic. See the Request for Value conditions.
For a resale flat, loan-to-value calculations use the lower of the agreed purchase price or valuation, subject to the buyer’s approved loan and applicable limits. CPF usage also has limits tied to that lower amount, the remaining lease and other CPF conditions. Neither figure means the whole purchase can be funded by a loan or CPF. Check CPF Board’s loan guidance and CPF housing usage limits. Our HDB loan calculator can help with an indicative budget.
Key point: valuation is not what you list at. It's not even what you negotiate. It's the reference point that shows up after you and the buyer have already agreed on a price.
2. Asking price (listing price)
The number on your PropertyGuru listing. Chosen by you and your agent. It's a marketing decision — high enough to leave negotiation room, low enough to actually attract viewings.
A higher asking price does not guarantee a higher offer. Compare it with registered sales and review buyer feedback before deciding whether to hold or adjust it.
3. Offer price (transaction price)
The price the buyer and seller agree. It may be above, equal to or below valuation. Any amount above valuation is Cash Over Valuation (COV), which the buyer must pay in cash, without CPF or a housing loan. COV is only one part of the buyer’s cash budget.
- Valuation — a reference for financing, subject to the lower purchase price and other limits
- Asking — what the listing shows
- Agreed price — what buyer and seller agree; only the amount above valuation is COV
What evidence supports your asking price?
Start with recent registered sales near your flat. An indicative range can support your asking-price decision, but it cannot guarantee HDB’s value or a buyer’s offer.

When does HDB valuation happen, before or after the OTP?
Here's what surprises sellers: HDB valuation only happens after you've agreed a price with the buyer. You can't get an "official" valuation upfront to price from. The request is made by the buyer or their salesperson, not by the bank.
So how do you price?
An agent can build an indicative price range from comparable sales before you list. This supports an asking-price discussion; it does not predict or replace the value determined through HDB’s process.

Buyers using CPF or a housing loan must submit a Request for Value by the next working day after the Option Date, unless their financial institution advises otherwise. The buyer pays a non-refundable $120 including GST. The result applies to that OTP and lasts three months from availability in the HDB Flat Portal; the resale application must be submitted within that period. Read HDB’s resale terms for the full conditions.
How do agents estimate an HDB flat’s value before it is listed?
Start with registered HDB resale transactions. Automated estimates are secondary checks; private-property data serves a different market.
1. HDB resale transaction data
HDB’s published resale records include the registered price, block, flat type, floor area, storey range, remaining lease and registration month. Start by comparing similar flats:
- Same block, past 6 months — if any
- Neighbouring blocks (same street or estate), past 6 months — check how many comparable sales are available
- Same flat type (4-room, 5-room etc.), same estate, past 12 months
Compare floor level, remaining lease, size and location before treating two sales as equivalent. Inspect condition separately: transaction records do not establish a fixed renovation premium. If few similar sales are available, explain that uncertainty rather than forcing a precise estimate.
2. Automated property estimates
Treat an automated estimate as a secondary reference. Check its date, the records behind it and whether it reflects your flat’s condition. A difference from recent registered sales is a reason to investigate, not proof of a pricing error.
3. Private-property data for your next purchase
URA private-property transaction data can help if you are also comparing condos or landed homes. It does not replace HDB resale records when pricing your HDB flat.
Check the transaction data yourself before you accept a price
Check the registered transactions behind an agent’s proposed range. These tools show transaction evidence and broader market context:
- Your block’s sold prices — every registered resale in your own block and street, with flat type, storey range, floor area and price. This is the evidence an indicative valuation should be built from.
- HDB resale prices by town — the 12-month median, median $psf and transaction count for all 26 towns, so you can see whether your estate is moving before you set an asking price.
- Condo resale prices by district — the same treatment from URA caveats, if the flat is funding a private purchase. Budget the next step with the affordability calculator.
If the comparables an agent shows you are not in that data, ask where they came from.
Worked examples: agreed price, valuation and COV
Illustrative figures only, not actual transactions, an official valuation or a loan approval. These examples show the arithmetic after a price and value are known. They do not estimate a floor or renovation premium.
| Amount | Price above valuation | Price below valuation |
|---|---|---|
| Agreed purchase price | $600,000 | $580,000 |
| Value determined through HDB | $588,000 | $588,000 |
| Lower of price or valuation | $588,000 | $580,000 |
| COV payable in cash | $12,000 | $0 |
In the first example, $600,000 minus $588,000 leaves $12,000 of COV. In the second, the agreed price is lower, so there is no COV; the higher valuation does not increase the financing reference beyond $580,000. The buyer still needs to budget for any required downpayment, fees and other cash costs. Loan approval and CPF usage limits are separate checks.
These figures do not predict sale speed. Finding a buyer and agreeing an OTP come before HDB’s processing stage. HDB describes completion as about eight weeks after acceptance of the resale application. See the HDB sale timeline for the stages.
Why sellers get the price wrong: four common mistakes
Pricing from an automated estimate alone
Ask which comparable transactions support the estimate and what assumptions it makes about your flat. Use an inspection and registered resale evidence to discuss any differences.
Anchoring on a neighbour's asking price
"My neighbour is asking $650k, so mine should be $640k." But is their flat actually selling at $650k? Or has it been listed for 14 weeks with no offers? Asking prices tell you what sellers want — transaction prices tell you what buyers pay. Only the latter is evidence.
Ignoring condition
Condition can affect a buyer’s willingness to pay, but renovation spending does not translate dollar-for-dollar into resale value. Compare the flat with similar registered sales and discuss repairs without assuming a fixed premium.
Assuming "cooling measures" cap your price
Eligibility, financing rules and market conditions can affect which buyers can proceed and what they can afford. Check the current rules and comparable transactions; a market headline alone does not establish a price for your flat.
What should you ask an agent before signing?
When I assess a flat for a seller, I walk them through:
- The 3–6 most comparable transactions around their flat (block, floor, condition, price)
- An indicative valuation built from those comparables
- A recommended listing price with the negotiation math explained
- A realistic lower bound — below which I'd advise against accepting
If an agent walks in, says "I think we can get $X", and can't show you the comparables that back that number, they're guessing. Get a second opinion.
For help turning an indicative price range into a listing and sale plan, see Joe's HDB selling service, including the pricing, marketing and resale support offered.
- "Let's start high and see what happens" — no.
- "The market is very strong right now" — maybe, but show me the 6 transactions that prove it for your flat type in your estate.
- "Don't worry about valuation, we'll handle it" — you can't "handle" HDB valuation. It is what it is.
- No mention of COV, buyer financing, or bank appraisal — the agent doesn't understand the full mechanics.
The bottom line
A good pricing call is a forecast built from data, adjusted for the specifics of your flat. It's a discussion, not a number handed down. When an agent prices your flat, you should finish the conversation understanding exactly why each figure was chosen and what would change if a different comparable closed next week.
Use that evidence to agree a pricing plan and the circumstances for reviewing it. Neither an indicative estimate nor the marketing plan guarantees the final price or sale date.
Frequently asked questions
When does HDB valuation happen?
The buyer’s Request for Value follows the OTP. Buyers using CPF or a housing loan must submit it by the next working day after the Option Date, unless their financial institution advises otherwise. HDB decides whether a valuation is required.
How much does an HDB valuation cost, and who pays?
The buyer pays $120 including GST for a Request for Value. The fee is non-refundable. The result applies to that OTP and is valid for three months from availability in the HDB Flat Portal; the resale application must be submitted within that period.
Can a seller get an official HDB valuation before listing?
Not through HDB’s resale Request for Value process: the buyer needs a granted OTP. Before listing, use comparable HDB resale transactions to discuss an indicative price range with an agent.
What is Cash Over Valuation (COV)?
COV is the amount by which the agreed purchase price exceeds valuation. It must be paid in cash, without CPF or a housing loan. At a price of $600,000 and valuation of $588,000, COV is $12,000. A price at or below valuation has no COV, but other cash costs may still apply.
Why is my flat's valuation lower than recent sales nearby?
Nearby transactions may differ in flat size, remaining lease, storey, condition and location. An asking price is also different from a registered sale price. Compare similar completed sales rather than assuming the highest nearby price applies to your flat.
