In cash terms the typical CF45 4 home went from £32,200 in 1995 to £149,000 in 2026, roughly 5 times the price. Inflation explains only part of it: in today's money the rise is still about 113%, a genuine increase in what a home here costs.
Year-on-year change in the CF45 4 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 2004 (+50.0% on the year before); the weakest, 2013 (−16.3%). 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) | +10.4% | +7.8% |
| 5 years (since 2021) | +6.3% | +1.4% |
| 10 years (since 2016) | +6.7% | +3.2% |
| 20 years (since 2006) | +3.0% | +0.2% |
Compound annual growth of the median sold price; the real column deflates by ONS CPIH. Annualised figures smooth the cycle (the chart above shows the cycle), and past growth is a record, not a forecast.
The turnover behind the prices
The year-by-year sales count
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, 47 sales completed in CF45 4. Like most of England and Wales, turnover never fully recovered from 2008: the market here averaged 155 sales a year before the financial crisis and 97 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.
The shape of the CF45 4 market
This is a thin market: 47 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 CF45 district median, CF45 4 sits 10% higher, marking it as a dearer pocket of the district.
Rents around CF45 4
For renting purposes CF45 4 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.
Average monthly rent by size, Rhondda Cynon Taf
ONS Price Index of Private Rents, May 2026.
£748 a month is £8,976 a year, which against the £149,000 median sold price makes a gross yield of 6.0%. 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.

What another bedroom costs in CF
The Land Registry record, split by size: what each kind of home actually sold for across the CF area. 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.

|---|---|---|---|---|---|
