What sells here
The mix of property types explains a large part of any area's median. Sierra Pines, Mountain Ash is dominated by the type at the top of this table, so its overall median leans that way.
| Property type | Sales | Share | Median paid | Range |
|---|---|---|---|---|
| Terraced | 54 | 69.2% | £75,000 | £19,000 – £150,000 |

Section 06
Ownership and new build in Sierra Pines, Mountain Ash
0 of the sales on record are leasehold and 78 freehold — 0.0% of the market. Tenure is not a detail: a leasehold flat and a freehold house are different assets, and mixing them into one median hides the difference.
| Category | Sales | Share | Median paid |
|---|---|---|---|
| Leasehold | 0 | 0.0% | — |
| Freehold | 78 | 100.0% | £81,250 |
A further 2 transfers for this area are on the register but are left out of every figure above. HM Land Registry marks them as additional price paid entries: repossessions, buy-to-let portfolio moves, transfers between companies or family, and sales at a discount such as right to buy. They are real records but they are not open-market prices, and including them would drag the median somewhere no buyer ever paid.
Section 09
How Sierra Pines, Mountain Ash compares
The median across the whole archive is £157,500. Sierra Pines, Mountain Ash sits below that national figure — -48.4%.
Within Mountain Ash the street ranks 56 of 225 by median price, and its median is above the town figure of £60,000 (+35.4%).
Where an EPC floor area could be matched to the sale, the median works out at £1,314 per square metre, across 25 of the 78 sales on record. Price per square metre is the only figure that compares a two-bed flat with a four-bed house honestly.
The full range on record runs from £19,000 to £365,000. Extremes usually mean something unusual — a plot sold without a house on it, a transfer between family members, or a very large property — so the median is the number to trust.
