25 ADDISON ROAD Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the West Northamptonshire local authority area over time, sourced from the HPI. The three 25 ADDISON ROAD sales between September 1995 and December 2008 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 June 2004 sale was for 32% below the HPI. So the extrapolation line tracks at 32% below the HPI over time, until the December 2008 sale, where it rises to 17% below the HPI. The line then continues to track at 17% below the HPI.

What might 25 ADDISON ROAD be worth now?

25 ADDISON ROAD might now be worth an estimated £236,484.

This is based on house price inflation of 89.2%, between December 2008 and July 2025, for semi-detached houses, in the West Northamptonshire local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).

The 89.2% inflationary increase is applied to the most recent sale price for 25 ADDISON ROAD of £125,000 on 3rd December 2008. For the value to have increased from £125,000 to £236,484 over the seventeen years and five months to July 2025, the following assumptions must hold true:

• The value of 25 ADDISON ROAD has moved in line with the HPI for semi-detached houses in the West Northamptonshire local authority area.
• The December 2008 sale price of £125,000 represented a fair market value for the property.
