The below graph shows the average detached house price in the North Somerset local authority area over time, sourced from the HPI. The four 71 GUILLEMOT ROAD sales between December 2009 and December 2018 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 2015 sale was for 13% above the HPI. So the extrapolation line tracks at 13% above the HPI over time, until the December 2018 sale, where it falls to 2% above the HPI. The line then continues to track at 2% above the HPI.
71 GUILLEMOT ROAD might now be worth an estimated £542,200.
This is based on house price inflation of 23.2%, between December 2018 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 23.2% inflationary increase is applied to the most recent sale price for 71 GUILLEMOT ROAD of £440,000 on 17th December 2018. For the value to have increased from £440,000 to £542,200 over the seven years and ten months to February 2025, the following assumptions must hold true:
