Goldmine Building sits in Chai Wan with about 520 units completed 1978–1978. Roughly 4.4% of its stock changes hands each year, the weighted commute to the main employment hubs is about 26 minutes, and the net rental yield after management fee, rates and a vacancy allowance works out at 2.48%.
The five pillars
The closer to the outer ring, the stronger. High liquidity means easy entry and exit; high yield means rent supports the price; short commute, younger stock and a solid developer hold value better.

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$80,391 | HK$40,195 |
| 5% | HK$133,984 | HK$66,992 |
| 8% | HK$214,375 | HK$107,188 |
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. At 48 years old, bank valuation and mortgage tenor also come into play, and a valuation shortfall is a legitimate lever on price.

Sourced from public pages on the listing portals for comparison only. What any individual flat trades at still depends on aspect, floor, condition and the seller's position.

Rental levels
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.
Best value on the market now: A座, asking about 11% below our estimate. Ask us what it should actually close at before you make an offer.
