In cash terms the typical CF45 home went from £30,000 in 1995 to £135,000 in 2026, roughly 5 times the price. Adjusted for inflation it still comes to a real rise of roughly 107%, so homes here got dearer in substance, not only in cash.
Year-on-year change in the CF45 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 (+42.0% on the year before); the weakest, 2013 (−15.4%). Single-year swings like these are why the annualised table below matters more than any one year's headline.
Detached, semi, terraced, flat: four markets in one
A single median hides the split beneath it. Sales of terraced homes dominate the record here, 77% of the typed total. In 2025, the last year both were recorded here, a detached home traded at £372,500 against £95,000 for a flat, 3.9 times the price.

The long view: annualised growth
| Period | Cash, per year | Real terms, per year |
|---|---|---|
| 1 years (since 2025) | +8.0% | +5.5% |
| 5 years (since 2021) | +7.3% | +2.3% |
| 10 years (since 2016) | +6.4% | +2.9% |
| 20 years (since 2006) | +3.4% | +0.6% |
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.
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.
The last five years, month by month
Monthly registrations. The sawtooth is seasonal; the register runs weeks behind completions at the right-hand edge.
CF45 recorded 160 sales in the last twelve months of data. Like most of England and Wales, turnover never fully recovered from 2008: the market here averaged 347 sales a year before the financial crisis and 194 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.
The rental side of CF45
The local authority for CF45 is Rhondda Cynon Taf, and its ONS average private rent currently stands at £748 a month (May 2026 figures). A one-bed averages £524 a month here and a four-or-more-bed £991, so size does most of the work in setting the rent.
Average monthly rent by size, Rhondda Cynon Taf
ONS Price Index of Private Rents, May 2026.
Against the £135,000 median purchase price, a rent of £748 a month (£8,976 a year) works out at a 6.6% 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.
How CF45 trades
The record here is jumpy: year-on-year moves of ten per cent or more are common in the chart above, mostly a function of which homes happened to sell rather than the market lurching. Among the 35 measurable districts of its area, CF45 ranks 30 by median price: towards the affordable end.

The price of an extra bedroom 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.
| Type | 1 bed | 2 bed | 3 bed | 4 bed | 5 bed |
|---|---|---|---|---|---|
| Detached | — | £275,000 | £367,000 (+33%) | £550,000 (+50%) | £790,000 (+44%) |
| Semi-detached | £190,000 | £217,000 (+14%) | £260,000 (+20%) | £380,000 (+46%) | £530,000 (+39%) |

| Flat | £140,000 | £180,000 (+29%) | £275,000 (+53%) | £417,500 (+52%) | — |
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. Blank cells mean too few homes for the figure to mean anything.
