In cash terms the typical CF23 9 home went from £39,100 in 1995 to £300,000 in 2026, roughly 8 times the price. Adjusted for inflation it still comes to a real rise of roughly 253%, so homes here got dearer in substance, not only in cash. In inflation-adjusted terms the high-water mark was 2021. 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 CF23 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 2021 (+41.7% on the year before); the weakest, 2017 (−20.4%). Single-year swings like these are why the annualised table below matters more than any one year's headline.
What CF23 9 has returned, per year

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.
Sales activity in CF23 9
Sales per year, counted
Recorded sales per year. The dip after 2008 is the financial crisis; the last bar is still filling in as recent sales get registered.
CF23 9 recorded 39 sales in the last twelve months of data. Like most of England and Wales, turnover never fully recovered from 2008: the market here averaged 180 sales a year before the financial crisis and 110 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 CF23 9 market
This is a thin market: 39 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.
What tenants pay around CF23 9
For renting purposes CF23 9 sits in Cardiff. The ONS average private rent there is £1,157 a month (May 2026). The spread runs from £894 a month for a typical one-bed to £1,677 at four-plus bedrooms, which is size doing most of the pricing.
Average monthly rent by size, Cardiff
ONS Price Index of Private Rents, May 2026.
Set against the £300,000 median sold price, £1,157 a month is £13,884 a year, a gross yield of 4.6%: 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.

Bedroom by bedroom: CF prices by size
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. Blank cells mean too few homes for the figure to mean anything.
