What COV actually is

When you agree on a resale price with a seller, HDB separately commissions a professional valuation of the flat. If your agreed price is higher than that valuation, the difference is called Cash-Over-Valuation (COV) — and critically, it must be paid entirely in cash. It cannot be covered by your CPF savings or by your housing loan, both of which are capped at the valuation amount (plus loan-to-value limits).

Why this matters

A $20,000 COV isn't just an extra cost — it's cash you need on hand at completion, on top of your downpayment, BSD and legal fees. Always ask what a realistic valuation range looks like before you agree on a price.

How to negotiate sensibly

  • Research recent transactions for similar units in the same block or estate — our Resale Transactions tool shows real block-by-block prices from the last 6 months.
  • Factor in floor, facing, renovation condition and remaining lease when comparing — two "4-room" flats can be worth very different amounts.
  • Remember the valuation is done after you agree a price, so you're negotiating somewhat blind — build in a buffer for the possibility of COV.
  • Don't be afraid to walk away if COV expectations are unreasonable relative to comparable transactions.

Remaining lease matters more than people expect

Flats with a shorter remaining lease face CPF usage restrictions once the lease runs below certain thresholds relative to the youngest buyer's age, and generally attract lower valuations. Always check remaining lease before falling in love with a unit's price.
