6 BRYN RHOSYN Price Paid vs. HPI Average

The below graph shows the average detached house price in the Cardiff local authority area over time, sourced from the HPI. The three 6 BRYN RHOSYN sales between December 1995 and December 2025 have been plotted on the graph. A line has been extrapolated to show what the value of the property might have been over time, following each sale, had it maintained the same margin above or below the HPI (as a percentage). For example, the February 2001 sale was for 29% below the HPI. So the extrapolation line tracks at 29% below the HPI over time, until the December 2025 sale, where it falls to 32% below the HPI. The line then continues to track at 32% below the HPI.

What might 6 BRYN RHOSYN be worth now?

6 BRYN RHOSYN might now be worth an estimated £352,719.

This is based on house price inflation of 0.8%, between December 2025 and May 2026, for detached houses, in the Cardiff local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 0.8% inflationary increase is applied to the most recent sale price for 6 BRYN RHOSYN of £350,000 on 17th December 2025. For the value to have increased from £350,000 to £352,719 over the one year and seven months to May 2026, the following assumptions must hold true:

• The value of 6 BRYN RHOSYN has moved in line with the HPI for detached houses in the Cardiff local authority area.
• The December 2025 sale price of £350,000 represented a fair market value for the property.
