How Mount Stuart Square, Cardiff prices moved
The chart tracks the median Mount Stuart Square, Cardiff house price for every year with a recorded sale, from 2002 to 2021. The dashed line restates each year in 2026 money, so the two lines separate exactly as much as inflation has eroded the cash figure.
| Decade | Years with sales | Median paid | In today's money |
|---|---|---|---|
| 2000s | 6 | £165,000 | £300,581 |
| 2010s | 4 | £150,000 | £211,500 |
| 2020s | 2 | £165,000 | £168,587 |
The highest yearly median on record for Mount Stuart Square, Cardiff is £185,000 in 2021; the lowest is £88,500 in 2017. Across the full 20-year record the cash median has moved from £133,000 to £185,000.
In 2026 money that first median is worth £256,539, so the real change over the whole record is -8.9% — about -0.49% a year after inflation. Cash growth and real growth are not the same story, and the gap is the part most price reports leave out.
Over the last decade alone the difference is stark: +6.8% in cash against -22.4% once inflation is removed. A buyer who sold at the end of that decade would have needed the real figure, not the headline one, to know whether they had actually gained.

The most recent sales
Every row is a completed sale as lodged with HM Land Registry. The right-hand column restates the price in 2026 money, which is the only fair way to compare a sale from the 1990s with one from last year.

Section 04
What sells here
The mix of property types explains a large part of any area's median. Mount Stuart Square, Cardiff is dominated by the type at the top of this table, so its overall median leans that way.
| Property type | Sales | Share | Median paid | Range |
|---|---|---|---|---|
| Flat or maisonette | 253 | 94.4% | £157,000 | £56,500 – £892,491 |
| Terraced | 9 | 3.4% | £250,000 | £35,750 – £480,000 |
| Semi-detached | 3 | 1.1% | £180,000 | £142,500 – £200,000 |

Section 06
Ownership and new build in Mount Stuart Square, Cardiff
254 of the sales on record are leasehold and 14 freehold — 94.8% of the market. Tenure is not a detail: a leasehold flat and a freehold house are different assets, and mixing them into one median hides the difference.
The median leasehold sale is £157,000 and the median freehold sale £267,500 — a gap of +70.4%. Most of that gap is property type rather than tenure itself: leasehold here is largely flats, freehold largely houses.
| Category | Sales | Share | Median paid |
|---|---|---|---|
| Leasehold | 254 | 94.8% | £157,000 |
| Freehold | 14 | 5.2% | £267,500 |
| New build | 133 | 49.6% | £150,000 |
| Existing home | 135 | 50.4% | £164,000 |
New builds sold for less than the median existing home — -8.5%. A new-build premium is normal: the buyer gets a warranty and nothing to fix, and the price is set by a developer rather than negotiated between two households.
A further 81 transfers for this area are on the register but are left out of every figure above. HM Land Registry marks them as additional price paid entries: repossessions, buy-to-let portfolio moves, transfers between companies or family, and sales at a discount such as right to buy. They are real records but they are not open-market prices, and including them would drag the median somewhere no buyer ever paid.
Section 09
How Mount Stuart Square, Cardiff compares
The median across the whole archive is £157,500. Mount Stuart Square, Cardiff sits above that national figure — +0.7%.
Within Cardiff the street ranks 1575 of 3205 by median price, and its median is above the town figure of £149,000 (+6.5%).
Where an EPC floor area could be matched to the sale, the median works out at £2,237 per square metre, across 58 of the 268 sales on record. Price per square metre is the only figure that compares a two-bed flat with a four-bed house honestly.
The full range on record runs from £35,750 to £892,491. Extremes usually mean something unusual — a plot sold without a house on it, a transfer between family members, or a very large property — so the median is the number to trust.
