In cash terms the typical CF39 9 home went from £31,500 in 1995 to £138,000 in 2026, roughly 4 times the price. Inflation explains only part of it: in today's money the rise is still about 102%, a genuine increase in what a home here costs.
Year-on-year change in the CF39 9 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 2003 (+30.2% on the year before); the weakest, 1997 (−22.3%). Single-year swings like these are why the annualised table below matters more than any one year's headline.
The long view: annualised growth
| Period | Cash, per year | Real terms, per year |
|---|---|---|
| 1 years (since 2025) | +15.0% | +12.3% |
| 5 years (since 2021) | +6.7% | +1.7% |
| 10 years (since 2016) | +7.8% | +4.2% |
| 20 years (since 2006) | +3.0% | +0.2% |
The table annualises median growth over each period, with the real column deflated by ONS CPIH. Smoothing hides the cycle (see the chart above for it), and none of this forecasts: it is the record.
The turnover behind the prices
How many homes change hands
Annual recorded sales. The post-2008 trough is the financial crisis; treat the final bar as provisional while registrations catch up.
CF39 9 recorded 43 sales in the last twelve months of data. Like most of England and Wales, turnover never fully recovered from 2008: the market here averaged 145 sales a year before the financial crisis and 84 a year over the last five. Price without volume misleads: a median built on few sales jumps around, and one street can tilt it. Keep in mind too that the latest year is still filling in, since sales reach the register weeks or months after completion.
What homes rent for around CF39 9
CF39 9 falls under Rhondda Cynon Taf, where the ONS puts the average private rent at £748 a month (May 2026 figures). 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.
Average monthly rent by size, Rhondda Cynon Taf
ONS Price Index of Private Rents, May 2026.
Against the £138,000 median purchase price, a rent of £748 a month (£8,976 a year) works out at a 6.5% gross yield, a ceiling figure that ignores letting costs, voids, maintenance and tax. Because rents are local-authority statistics, districts sharing the authority share the figure.
The shape of the CF39 9 market
This is a thin market: 43 sales in the last twelve months of data. With that few transactions, one street selling well (or one block of cheap transfers) can move the median, so read the year lines as a range rather than a verdict. 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 9 sits 8% lower, marking it as a cheaper pocket of the district.

What another bedroom costs in CF
Real sold prices by size across the CF area, straight from the Land Registry record. The jump between sizes is local: in some areas a third bedroom adds a quarter to the price, in others nearly four fifths, so a national rule of thumb will mislead you here.

|---|---|---|---|---|---|
| Detached | — | £275,000 | £367,000 (+33%) | £550,000 (+50%) | £790,000 (+44%) |

Four years of recorded sales, split by built form and bedroom count. The register does not state bedrooms, so sizes come from each home's EPC record and a few homes will land one size out. Sizes with too few homes to be meaningful are left blank.
