A resale buyer and seller can agree on a price without HDB deciding that the flat is worth exactly that amount for financing purposes.
This is one of the most important distinctions in the HDB resale system.
The agreed price answers:
What price did this buyer and seller agree for this flat?
The HDB value answers a different question:
What value will form the basis for CPF usage and the relevant housing-loan reference?
HDB’s Request for Value process is the bridge between those two numbers.

This article reflects HDB guidance available on 4 September 2026.
Quick Answer
After the seller grants the HDB-prescribed OTP, a buyer using CPF savings and/or a housing loan must submit a Request for Value through My Flat Dashboard.
HDB currently requires the request by the next working day after the Option Date, together with the required OTP page and a processing fee of $120 including GST.
HDB states that the outcome is typically available within 10 working days. The outcome is valid for 3 months, and the buyer and seller must submit their resale applications within that validity period or a new Request for Value will be required for the same transaction.
Official HDB guidance: Request for Value for a Resale Flat.
The mechanism is:
AGREED RESALE PRICE → OTP GRANTED → REQUEST FOR VALUE → HDB VALUE OUTCOME → CPF / LOAN BASIS → COMPARE VALUE WITH AGREED PRICE → EXERCISE OR DO NOT EXERCISE OTP
Wait, What? HDB Does Not Give You the Value Before You Negotiate
Under the current process, buyer and seller first negotiate and agree on the resale price.
The seller then grants the OTP.
Only after that does the buyer request the flat value.
This means the buyer cannot simply ask HDB:
Tell me the valuation and I will offer exactly that.
The market negotiation happens first.
HDB valuation enters afterwards as the financing anchor.
Why Separate Market Price From Financing Value?
Because one individual buyer can be unusually enthusiastic.
One seller can be unusually reluctant.
A negotiated price can include subjective value attached to:
- specific floor;
- orientation;
- renovation;
- proximity to parents;
- school logistics;
- view;
- urgency;
- scarcity of similar units.
CPF and housing finance need a more disciplined reference than one pair of negotiating preferences.
The valuation layer creates that reference.
The Value Is a Financing Boundary
HDB states that the Request for Value outcome forms the basis for CPF usage and/or the reference for the housing-loan amount from HDB or a financial institution, unless the financial institution advises otherwise under its own valuation process.
That means the value is not merely informational.
It constrains what kinds of money can support the purchase.
Cash-Only Buyers Do Not Need a Request for Value
HDB currently states that a buyer paying entirely in cash, with no CPF usage and no housing loan, does not need to submit a Request for Value.
Why?
Because the value’s main operational job is to govern CPF and financing.
If neither system is being used, that particular financing anchor is unnecessary for the purchase path.
Why the Request Must Be Made Quickly
The OTP lasts 21 calendar days.
The buyer must obtain the value before exercising if CPF or a housing loan will be used.
HDB therefore requires the Request for Value by the next working day after the Option Date.
This keeps the valuation process inside the contract decision window.
Sometimes a Physical Valuation Inspection Is Needed
HDB states that if a formal valuation of the flat is required, an appointed valuer will contact the seller to arrange an inspection.
Not every request therefore follows an identical physical inspection path.
The system determines whether additional valuation work is needed.
The Outcome Is Not Permanent
HDB currently gives the Request for Value outcome a 3-month validity period from the date it becomes available in My Flat Dashboard.
This makes sense because property markets change.
A value used to anchor one transaction should not remain valid indefinitely while the market, lease and transaction state move on.
Agreed Price Below Value
Suppose the buyer and seller agree on $650,000 and the value outcome is $670,000.
The purchase price is still $650,000.
The valuation does not force the buyer to pay $670,000.
A value is not a minimum selling price.
The transaction remains based on the true agreed price.
Agreed Price Equal to Value
If the agreed price and HDB value are the same, there is no price-above-value gap.
The financing calculation still depends on loan and CPF rules, but Cash Over Valuation is zero.
Agreed Price Above Value
Suppose the buyer and seller agree on $700,000 and HDB’s value is $680,000.
The $20,000 difference is the COV.
CPF Board’s current guidance states that this amount cannot be paid with CPF OA savings and must be paid in cash.
The next article owns that cash-gap mechanism.
Valuation Does Not Tell You Whether a Flat Is “Worth It” to You
A household may rationally pay above valuation because the location has unusually high personal value.
Living next door to ageing parents may save hours of travel every week.
A rare floor plan may fit a caregiving arrangement.
A particular school or transport node may transform daily logistics.
Valuation does not erase subjective value.
It simply refuses to let CPF and mortgage financing automatically fund every subjective premium.
Recent Transaction Data Helps Before the Value Is Known
HDB advises buyers to check recent transacted resale prices when deciding what to pay.
This is important because the buyer must negotiate before receiving the Request for Value outcome.
Past transactions do not guarantee the value of the next flat.
They provide a market reference that can reduce blind bidding.
Why Renovation Does Not Translate Dollar-for-Dollar Into Value
A seller may have spent $100,000 renovating the flat.
That does not mean the valuation rises by $100,000.
Renovation is partly consumption.
Some features may suit the buyer.
Others may be removed immediately.
Market value is not a reimbursement schedule for the seller’s interior-design budget.
Remaining Lease Sits Inside the Asset
An HDB flat is a leasehold housing asset.
Two otherwise similar flats with materially different remaining leases do not carry identical long-term housing claims.
Lease interacts with market value, CPF usage and financing.

Failure Mode: Calling the HDB Value the “Correct Price”
The market price is what the buyer and seller actually agree, subject to the rules.
The HDB value is the financing reference used in the resale process.
They can match.
They do not have to.
Failure Mode: Assuming Valuation Will Rescue an Over-Aggressive Offer
The buyer agrees to a high price and thinks:
If HDB values it lower, we can just borrow the difference somehow.
That is exactly the risk COV exposes.
The amount above valuation must be planned as cash, not imagined as automatically financeable housing value.
Failure Mode: Treating the Value as a Prediction of Future Resale Price
The Request for Value supports the current transaction.
It does not guarantee what another buyer will pay five or ten years later.
Future price depends on future demand, lease, policy, interest rates, town development and market conditions.
Forward Play: Follow the Two Numbers
Buyer and seller create one number through negotiation.
HDB’s Request for Value creates another number for financing purposes.
If they match, the transaction has no COV.
If purchase price is higher, the difference becomes cash-only.
If purchase price is lower, the buyer still pays the lower agreed purchase price.
Valuation therefore does not set the bargain.
It sets a financial boundary around the bargain.
Reverse Play: Start From the COV
A buyer discovers $30,000 COV.
Work backwards.
The agreed price exceeded the HDB value by $30,000.
That happened because negotiation occurred before valuation.
The COV is therefore not a mysterious extra fee.
It is the arithmetic gap between two different kinds of price signal.
The Deeper Finance Principle
Markets can decide what people are willing to pay.
Lenders and savings systems still need to decide what value they are willing to recognise for financing.
Those functions should not be confused.
A market can contain enthusiasm.
A financing system needs boundaries.
The Deepest Answer
HDB resale valuation works because a resale flat has two simultaneous truths.
It has the price two people are willing to transact at.
And it has a value the housing-finance system is willing to recognise for CPF and loan purposes.
When those numbers are the same, the distinction disappears from view.
When they separate, the buyer suddenly sees why the distinction was necessary.
The Request for Value does not tell the household what the flat means to them.
It tells the financing system where its recognised value stops.
