17 THE GARSTONS Price Paid vs. HPI Average

The below graph shows the average detached house price in the North Somerset local authority area over time, sourced from the HPI. The two 17 THE GARSTONS sales from October 2006 and December 2020 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 October 2006 sale was for 24% below the HPI. So the extrapolation line tracks at 24% below the HPI over time, until the December 2020 sale, where it falls to 25% below the HPI. The line then continues to track at 25% below the HPI.

What might 17 THE GARSTONS be worth now?

This is based on house price inflation of 14.9%, between December 2020 and February 2025, for detached houses, in the North Somerset local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 14.9% inflationary increase is applied to the most recent sale price for 17 THE GARSTONS of £347,000 on 9th December 2020. For the value to have increased from £347,000 to £398,725 over the five years and ten months to February 2025, the following assumptions must hold true:
