What does COV mean in HDB resale?

COV stands for cash over valuation: the amount by which the agreed resale price exceeds HDB’s official valuation of the flat. That difference must be paid in cash. It cannot come from CPF savings or a housing loan.

Why do I only find out the valuation after agreeing on a price?

Since 2014, HDB only accepts a valuation request after buyer and seller have agreed on price and an option has been granted. The rule was introduced to stop COV from being used as the headline negotiation number, which was inflating prices.

How do I avoid paying high COV?

Anchor your offer on the block’s recent transacted prices rather than the asking price. Valuers look at the same recent transactions you can see, so an offer near the recent median for that block and flat type usually lands near valuation.

Is COV negotiable or refundable?

COV is not a fee, it is just the cash portion of the price you agreed. If the valuation comes in low and the gap is bigger than you can fund, you can choose not to exercise the option, forfeiting the option fee of up to $1,000.

COV: cash over valuation

Why you only learn the valuation after agreeing on price, and how recent block sales protect you.

The gap you pay in cash

Every HDB resale deal has two numbers: the price you agreed, and the valuation HDB assigns. Loans and CPF can only stretch to the valuation. Anything above it, the cash over valuation, comes out of the buyer’s pocket, in actual cash, before anything else is disbursed.

Agree to pay $700,000 for a flat valued at $670,000 and you need $30,000 in cash on top of your downpayment. That is the entire concept.

Why the valuation hides until you commit

Here is the part that catches first-time buyers. You negotiate the price first. Only after the seller grants an Option to Purchase can you request the valuation. In hot markets sellers know this and price ahead of the last done deal, betting the buyer will swallow the gap rather than walk away from the option fee.

HDB designed it this way on purpose. Before 2014, agents marketed flats by their expected COV, and the cash premium became the negotiation itself. Hiding the valuation until after the handshake killed that practice, but it moved the burden onto buyers to know the data.

The data is the defence

Valuers do not pull numbers from the air. They lean on recent transactions in the same block and nearby, adjusted for floor, size, and remaining lease. Which means you can roughly predict the valuation yourself: look at what the block actually transacted at recently, for your flat type, around your storey range.

Every block page on Property Beep lists exactly those sales, back to 1990, with the 12-month median worked out for you. Find your block before you make an offer, and set a beep so every new sale in that block lands in your inbox while you hunt.
