49 BRYN DERWEN 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 two 49 BRYN DERWEN sales from November 2002 and September 2017 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 November 2002 sale was for 39% below the HPI. So the extrapolation line tracks at 39% below the HPI over time, until the September 2017 sale, where it falls to 44% below the HPI. The line then continues to track at 44% below the HPI.

What might 49 BRYN DERWEN be worth now?

This is based on house price inflation of 39.8%, between September 2017 and February 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 39.8% inflationary increase is applied to the most recent sale price for 49 BRYN DERWEN of £210,000 on 15th September 2017. For the value to have increased from £210,000 to £293,610 over the eight years and seven months to February 2025, the following assumptions must hold true:
