6 BRYN BRIALLU 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 BRIALLU sales between August 2017 and December 2023 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 March 2021 sale was for 73% above the HPI. So the extrapolation line tracks at 73% above the HPI over time, until the December 2023 sale, which was also at 73% above the HPI.

What might 6 BRYN BRIALLU be worth now?

This is based on house price inflation of 3.7%, between December 2023 and June 2025, 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 3.7% inflationary increase is applied to the most recent sale price for 6 BRYN BRIALLU of £862,500 on 18th December 2023. For the value to have increased from £862,500 to £894,073 over the two years and six months to June 2025, the following assumptions must hold true:
