In cash terms the typical CF39 home went from £34,000 in 1995 to £150,000 in 2026, roughly 4 times the price. Inflation explains only part of it: in today's money the rise is still about 103%, a genuine increase in what a home here costs. In inflation-adjusted terms the high-water mark was 2022. The market now sits about 14% below it, so a peak-time purchase has yet to recover its real value.
Year-on-year change in the CF39 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 (+40.0% on the year before); the weakest, 2009 (−10.6%). 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, 56% of the typed total. In 2023, the last year both were recorded here, a detached home traded at £295,000 against £55,000 for a flat, 5.4 times the price.

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.
Transaction volumes
How many homes change hands
Recorded sales per year. The dip after 2008 is the financial crisis; the last bar is still filling in as recent sales get registered.
The monthly pulse, last five years
Registrations by month. The repeating sawtooth is seasonality, and the right-hand edge always dips because the register lags completions.
CF39 recorded 277 sales in the last twelve months of data. Like most of England and Wales, turnover never fully recovered from 2008: the market here averaged 511 sales a year before the financial crisis and 319 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.
Rents around CF39
CF39 falls under Rhondda Cynon Taf, where the ONS puts the average private rent 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 £150,000 median purchase price, a rent of £748 a month (£8,976 a year) works out at a 6.0% 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.

What another bedroom costs in CF
Real sold prices by size across the CF area, straight from the Land Registry record. 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.

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

Built from the last four years of recorded sales by form and bedroom count. Bedroom counts are estimated from EPC records (the register carries none), so expect a small number of homes one size adrift. Sizes with too few homes to be meaningful are left blank.
