In cash terms the typical CF23 home went from £60,000 in 1995 to £300,000 in 2026, roughly 5 times the price. Inflation explains only part of it: in today's money the rise is still about 130%, a genuine increase in what a home here costs. The real-terms peak came in 2021, and today's median remains roughly 20% under it: a 2021 buyer is still waiting to get that price back in today's money.
Year-on-year change in the CF23 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 2002 (+35.6% on the year before); the weakest, 2023 (−5.9%). Single-year swings like these are why the annualised table below matters more than any one year's headline.
Growth per year, over one to twenty years
| Period | Cash, per year | Real terms, per year |
|---|---|---|
| 1 years (since 2025) | +3.4% | +1.0% |
| 5 years (since 2021) | +0.3% | −4.3% |
| 10 years (since 2016) | +3.2% | −0.2% |
| 20 years (since 2006) | +2.8% | 0.0% |
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.
Detached, semi, terraced, flat: four markets in one
A single median hides the split beneath it. Sales of terraced homes dominate the record here, 32% of the typed total. A detached home currently trades at £487,500 against £169,000 for a flat, 2.9 times the price.

The turnover behind the prices
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 last five years, month by month
Sales as they reached the register each month. Expect the seasonal sawtooth, and discount the newest months while late entries land.
The register shows 474 CF23 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 989 sales a year before the financial crisis and 497 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.
What kind of market CF23 is
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. Among the 35 measurable districts of its area, CF23 ranks 7 by median price: firmly in the dearer tier.
Rents around CF23
For renting purposes CF23 sits in Cardiff. The ONS average private rent there is £1,157 a month (May 2026). 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.
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.

What another bedroom costs in CF
What homes of each size actually sold for across the CF area, from the Land Registry record. 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%) | — |
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. Where too few homes exist to say anything meaningful, the cell is blank.
