20 BLACKTHORN SQUARE Price Paid vs. HPI Average

The below graph shows the average terraced house price in the North Somerset local authority area over time, sourced from the HPI. The four 20 BLACKTHORN SQUARE sales between September 1998 and October 2025 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 January 2018 sale was for 8% above the HPI. So the extrapolation line tracks at 8% above the HPI over time, until the October 2025 sale, where it rises to 13% above the HPI. The line then continues to track at 13% above the HPI.

What might 20 BLACKTHORN SQUARE be worth now?

This is based on house price inflation of 3.5%, between October 2025 and May 2026, for terraced 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 3.5% inflationary increase is applied to the most recent sale price for 20 BLACKTHORN SQUARE of £295,000 on 17th October 2025. For the value to have increased from £295,000 to £305,195 over the one year and five months to May 2026, the following assumptions must hold true:

• The value of 20 BLACKTHORN SQUARE has moved in line with the HPI for terraced houses in the North Somerset local authority area.
• The October 2025 sale price of £295,000 represented a fair market value for the property.
