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.
Annualised returns
| Period | Cash, per year | Real terms, per year |
|---|---|---|
| 1 years (since 2025) | +19.0% | +19.0% |
| 5 years (since 2021) | +7.6% | +3.1% |
| 10 years (since 2016) | +6.6% | +3.3% |
| 20 years (since 2006) | +3.0% | +0.3% |
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.
CF45 4 recorded 31 sales in the last twelve months of data. 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 113 a year over the last five. Volume matters as much as price: when few homes change hands, the median gets jumpy and a single street can move the figure. The most recent year is always still filling in, because sales appear in the Land Registry weeks or months after completion.
What homes rent for around CF45 4
CF45 4 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.
Set against the £149,000 median sold price, £748 a month is £8,976 a year, a gross yield of 6.0%: gross, before letting costs, voids, maintenance and tax, so a ceiling rather than a promise. Rents are published at local-authority level, so nearby districts in the same authority share these figures.
Will CF45 4 prices rise from here?
Nobody can tell you that, and this page will not pretend to. What the record shows: the median is up 44% over five years in cash and up 16% after inflation. If you are weighing a purchase, read the volume chart alongside the price one, and remember that every figure here is a completed sale, lagged by the weeks it takes the Land Registry to register it.

How this page is made: the statistics are computed from HM Land Registry Price Paid Data (Crown copyright, OGL v3.0), geocoded to address level; inflation adjustment uses the ONS CPIH index; rents are the ONS Price Index of Private Rents at local-authority level. Medians of recorded sales, not valuations. Nothing on this page is financial advice.
