How Maes Y Ffynnon, Mountain Ash prices moved
The chart tracks the median Maes Y Ffynnon, Mountain Ash house price for every year with a recorded sale, from 2008 to 2021. The dashed line restates each year in 2026 money, so the two lines separate exactly as much as inflation has eroded the cash figure.
| Decade | Years with sales | Median paid | In today's money |
|---|---|---|---|
| 2000s | 2 | £103,000 | £187,636 |
| 2010s | 2 | £99,995 | £140,993 |
| 2020s | 1 | £140,500 | £143,554 |
The highest yearly median on record for Maes Y Ffynnon, Mountain Ash is £140,500 in 2021; the lowest is £99,995 in 2010. Across the full 14-year record the cash median has moved from £103,000 to £140,500.
In 2026 money that first median is worth £172,893, so the real change over the whole record is +2.7% — about +0.20% a year after inflation. Cash growth and real growth are not the same story, and the gap is the part most price reports leave out.
Over the last decade alone the difference is stark: +40.5% in cash against +11.2% once inflation is removed. A buyer who sold at the end of that decade would have needed the real figure, not the headline one, to know whether they had actually gained.

The most recent sales

Section 04
What sells here
The mix of property types explains a large part of any area's median. Maes Y Ffynnon, 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 | 67 | 70.5% | £104,995 | £75,000 – £178,000 |
| Semi-detached | 22 | 23.2% | £112,500 | £75,000 – £175,000 |
| Detached | 5 | 5.3% | £161,000 | £155,000 – £274,950 |
| Flat or maisonette | 1 | 1.1% | £97,500 | £97,500 – £97,500 |
Section 06
Ownership and new build in Maes Y Ffynnon, Mountain Ash
1 of the sales on record are leasehold and 94 freehold — 1.1% 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.
The median leasehold sale is £97,500 and the median freehold sale £108,000 — a gap of +10.8%. Most of that gap is property type rather than tenure itself: leasehold here is largely flats, freehold largely houses.
| Category | Sales | Share | Median paid |
|---|---|---|---|
| Leasehold | 1 | 1.1% | £97,500 |
| Freehold | 94 | 98.9% | £108,000 |
| New build | 37 | 38.9% | £105,000 |
| Existing home | 58 | 61.1% | £114,998 |
New builds sold for less than the median existing home — -8.7%. A new-build premium is normal: the buyer gets a warranty and nothing to fix, and the price is set by a developer rather than negotiated between two households.
A further 1 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 Maes Y Ffynnon, Mountain Ash compares
The median across the whole archive is £157,500. Maes Y Ffynnon, Mountain Ash sits below that national figure — -31.4%.
Within Mountain Ash the street ranks 29 of 225 by median price, and its median is above the town figure of £60,000 (+80.0%).
No EPC floor areas could be matched to these sales, so no price per square metre is published here. An estimate would be a guess, and the archive does not publish guesses.
The full range on record runs from £75,000 to £274,950. 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.

Quick answers
Common questions about this data
What is the average house price in Maes Y Ffynnon, Mountain Ash?
The median price paid in Maes Y Ffynnon, Mountain Ash across every sale on the register is £108,000. The median is used rather than the mean because a handful of very large sales would otherwise drag the average away from what a typical buyer paid.
How many homes have sold in Maes Y Ffynnon, Mountain Ash?
95 sales are on record for Maes Y Ffynnon, Mountain Ash, the most recent completing on 29 Jan 2026. Every one is a completed transfer lodged with HM Land Registry, not an asking price or an estimate.
Have Maes Y Ffynnon, Mountain Ash house prices actually risen?
In cash, the median rose +40.5% between 2010 and 2021. In 2026 money — that is, after inflation — the change is +11.2%. Both numbers are true; only the second one tells you whether buying here preserved value.
When were Maes Y Ffynnon, Mountain Ash house prices at their highest?
The highest yearly median on record is £140,500, set in 2021. That is the cash figure; measured in 2026 money the peak may fall in a different year, because inflation reshapes the series.

No EPC floor areas could be matched to these sales, so no price per square metre is published for this area. Nothing is estimated to fill the gap.
How current is this data?
The latest sale shown here completed on 29 Jan 2026. HM Land Registry publishes Price Paid Data monthly and a sale can take a month or two to appear after completion, so the most recent weeks are always incomplete.
