A discount to market: what the number is measured against, and when to distrust it

Every listing platform in this market has learned to put a percentage next to a price. The percentage is meaningless on its own, because a discount is a gap between two numbers and the second one is almost never stated. So here is the second one, for the figures we publish, and the conditions under which it should not be trusted.

What the badge compares against

The gap is measured against the median price of comparable stock: the same project where the project is large enough to have one, or the same class of building in the same district; the same property type; a similar size. It is computed automatically against the current sample and recalculated nightly, not typed in by a broker who wants the lot to look attractive.

That has a specific implication people usually miss. The badge is exactly as reliable as the comparables behind it — no more. It is not an appraisal, it is not a valuation for lending purposes, and it is not a claim about what the property will be worth later. It is one sentence: this asking price sits this far below the middle of what similar stock is currently priced at.

A lot carrying no badge is not defective. It means the price is in line with comparable stock, that any reduction has to be negotiated from scratch, and that the reason to buy is the property rather than the entry price.

When the number is solid and when it is an estimate

The quality of a discount figure tracks the depth of the sample it was computed against, and that varies enormously across this market.

• Solid: a standard studio or one-bedroom in a large scheme with dozens of near-identical units on the market at once. Here −20% genuinely means the equivalent flat costs about a fifth more.
• Indicative: a mid-size building with a handful of comparables. The direction is real, the magnitude is soft.
• Unreliable: penthouses, duplexes, one-off villa layouts, anything where the comparison set is a few properties that are not really alike. Rare property compares badly by construction, not by carelessness.

Three things the calculation cannot see

No automated comparison has access to the interior condition, the view, or the floor. All three are genuine price determinants inside a single building: a unit facing the neighbouring tower's wall and one facing the canal trade at different prices for good reason, and part of a headline discount is sometimes that reason rather than any distress on the seller's side.

This is why a viewing is not a formality even on a well-evidenced discount. The viewing tells you which part of the gap is the seller's situation and which part was always priced into that particular unit.

Not the same thing as a developer discount

A developer announcing "20% off at launch" is discounting a price he set himself, and the only reference point is his own next price list. It is a sales instrument.

A discount on a resale is measured against what comparable property is actually priced at now. The difference matters at the exit rather than the entry: you will resell at market, not at a developer's list price, so a gap to the market converts into a result and a gap to a list price does not always.

When a real discount is still not a bargain

• When the property is illiquid. Twenty per cent below market in a project where a deal closes once a quarter is a paper gain and a real problem on the way out. Look at how many comparable units actually sold recently, not only at the entry price.
• When the unit explains the price. Ground floor facing the service road, a bedroom without a window, a building with a reputation. That is not distress, that is what such a unit costs — and the same discount will be waiting for you when you sell.
• When the building explains it. Poor management, lifts permanently out, an owners' association in litigation, service charges at twice the neighbours'. That kind of gap is not a one-off; it stays with you.
• When transaction costs eat it. Budget roughly 7–8% above the price on a cash purchase — the 4% Land Department transfer fee plus administrative charges, 2% agency commission plus VAT on resale, trustee fees, and the developer's NOC fee. A property bought 7% below market and sold a year later hands the discount back in fees. (Fee levels as at 2025; confirm the components at the time of the deal.)

The five questions

Ask these of any discount number, ours included: what is the reference price; is it a mean or a median; how many comparables sit behind it; when was it last recalculated; and what would explain this gap other than the seller's situation. A source that can answer all five is publishing a measurement. One that cannot is publishing an adjective.
