Price band
Enter saleable area and floor to get this estate's transacted price band and what a negotiation is worth.
| Reduction | Saved | Net of our fee |
|---|---|---|
| 3% | HK$523,545 | HK$261,773 |
| 5% | HK$872,575 | HK$436,288 |
| 8% | HK$1,396,120 | HK$698,060 |
Saved = band midpoint × reduction; net = saved ÷ 2. Real room depends on the seller's position, the bank valuation and same-period comparables.
The negotiating read
Transactions are steady but not constant, so a stale listing and a seller with a deadline are where the discount actually appears.

Taken from the live rental listings on the major portals — the check on yield, and on how easily the flat lets.
The whole-estate average the portals publish, across all layouts.
Is the asking price fair?
We value each listing against this estate's own reported deals, weighting recent deals more heavily and adjusting for deal date, saleable area, floor level and block, and show the price we would negotiate towards. Where deals are too thin, we fall back to the live asking distribution — the method used is stated below the table.
