In cash terms the typical CF39 8 home went from £35,000 in 1995 to £175,000 in 2026, roughly 5 times the price. Inflation explains only part of it: in today's money the rise is still about 130%, a genuine increase in what a home here costs. In inflation-adjusted terms the high-water mark was 2022. The market now sits about 17% below it, so a peak-time purchase has yet to recover its real value.
Year-on-year change in the CF39 8 median
Each bar is the change on the year before, in cash. The zero line is the boundary between rising and falling.
The strongest year on record here is 2002 (+40.4% on the year before); the weakest, 2011 (−15.4%). Single-year swings like these are why the annualised table below matters more than any one year's headline.
Growth per year, over one to twenty years
| Period | Cash, per year | Real terms, per year |
|---|---|---|
| 1 years (since 2025) | −1.7% | −4.0% |
| 5 years (since 2021) | +2.1% | −2.6% |
| 10 years (since 2016) | +3.6% | +0.2% |
| 20 years (since 2006) | +2.6% | −0.2% |
Each row is compound annual growth of the median; ONS CPIH supplies the real-terms deflator. Annualising irons out the cycle, which the chart above shows in full, and past growth records what happened rather than predicting anything.
Sales activity in CF39 8
Sales per year, counted
Annual recorded sales. The post-2008 trough is the financial crisis; treat the final bar as provisional while registrations catch up.
Over the last twelve months of data, 78 sales completed in CF39 8. Like most of England and Wales, turnover never fully recovered from 2008: the market here averaged 262 sales a year before the financial crisis and 178 a year over the last five. Watch the volume as closely as the price. Thin years make jumpy medians, where one street's sales can move the figure, and the newest year is always incomplete because registrations trail completions by weeks or months.
How CF39 8 trades
Expect volatility in the annual figures: swings past ten per cent show up repeatedly above, and they usually reflect the mix of homes sold in a given year rather than genuine repricing. Against the CF39 district median, CF39 8 sits 17% higher, marking it as a dearer pocket of the district.
Rents around CF39 8
For renting purposes CF39 8 sits in Rhondda Cynon Taf. The ONS average private rent there is £748 a month (May 2026). The spread runs from £524 a month for a typical one-bed to £991 at four-plus bedrooms, which is size doing most of the pricing.

ONS Price Index of Private Rents, May 2026.
£748 a month is £8,976 a year, which against the £175,000 median sold price makes a gross yield of 5.1%. Gross means before letting costs, voids, maintenance and tax: treat it as a ceiling. The ONS publishes rents by local authority, so neighbouring districts under the same authority share these numbers.

Moving up a bedroom in CF: the cost
The Land Registry record, split by size: what each kind of home actually sold for across the CF area. Size steps are fiercely local. A third bedroom adds a quarter to the price in some areas and close to four fifths in others, which is why no national rule of thumb survives contact with a real market.
