23 BLACKDOWN WAY Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the West Berkshire local authority area over time, sourced from the HPI. The two 23 BLACKDOWN WAY sales from October 1999 and December 2005 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 1999 sale was for 19% below the HPI. So the extrapolation line tracks at 19% below the HPI over time, until the December 2005 sale, which was also at 19% below the HPI.

What might 23 BLACKDOWN WAY be worth now?

This is based on house price inflation of 97.4%, between December 2005 and June 2025, for semi-detached houses, in the West Berkshire local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 97.4% inflationary increase is applied to the most recent sale price for 23 BLACKDOWN WAY of £165,500 on 2nd December 2005. For the value to have increased from £165,500 to £326,660 over the twenty years and six months to June 2025, the following assumptions must hold true:
