CF23 6 is a postcode sector: one group of streets inside CF23 (Cardiff). This is as local as the public record gets, but sector medians move on fewer sales than a district's, so expect the lines to be lumpier.

In cash terms the typical CF23 6 home went from £81,500 in 1995 to £363,500 in 2026, roughly 4 times the price. Even after inflation that is a real rise of about 105%: homes here genuinely became dearer, not merely more expensive on paper. The real-terms peak came in 2022, and today's median remains roughly 29% under it: a 2022 buyer is still waiting to get that price back in today's money.
Year-on-year change in the CF23 6 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 1997 (+32.0% on the year before); the weakest, 2026 (−18.5%). 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) | −18.5% | −20.4% |
| 5 years (since 2021) | −0.7% | −5.3% |
| 10 years (since 2016) | +1.8% | −1.5% |
| 20 years (since 2006) | +2.2% | −0.6% |
The table annualises median growth over each period, with the real column deflated by ONS CPIH. Smoothing hides the cycle (see the chart above for it), and none of this forecasts: it is the record.
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 register shows 34 CF23 6 sales across the most recent twelve months of data. Like most of England and Wales, turnover never fully recovered from 2008: the market here averaged 170 sales a year before the financial crisis and 98 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.
Reading the CF23 6 market
Only 34 sales completed here in the last twelve months of data, which makes CF23 6 a thin market. Each figure rests on few transactions, so single streets can swing the median and the charts deserve a sceptical squint. 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. Within CF23, this sector trades 21% above the district median: one of the dearer corners of its district.
The rental side of CF23 6
CF23 6 falls under Cardiff, where the ONS puts the average private rent at £1,157 a month (May 2026 figures). Size sets most of the rent: one-beds average £894 a month here against £1,677 for four or more bedrooms.
Average monthly rent by size, Cardiff
ONS Price Index of Private Rents, May 2026.
£1,157 a month is £13,884 a year, which against the £363,500 median sold price makes a gross yield of 3.8%. 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.
| 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%) |

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.
