1 BLACKTHORN DRIVE 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 three 1 BLACKTHORN DRIVE sales between November 1998 and September 2004 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 April 2003 sale was for 1% above the HPI. So the extrapolation line tracks at 1% above the HPI over time, until the September 2004 sale, where it falls to 6% below the HPI. The line then continues to track at 6% below the HPI.

What might 1 BLACKTHORN DRIVE be worth now?

This is based on house price inflation of 98.7%, between September 2004 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 98.7% inflationary increase is applied to the most recent sale price for 1 BLACKTHORN DRIVE of £249,950 on 24th September 2004. For the value to have increased from £249,950 to £496,591 over the 21 years and seven months to February 2025, the following assumptions must hold true:
