17 DOWNING WAY Price Paid vs. HPI Average

The below graph shows the average detached house price in the West Northamptonshire local authority area over time, sourced from the HPI. The three 17 DOWNING WAY sales between March 1996 and November 2015 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 August 2003 sale was for 10% below the HPI. So the extrapolation line tracks at 10% below the HPI over time, until the November 2015 sale, where it falls to 17% below the HPI. The line then continues to track at 17% below the HPI.

What might 17 DOWNING WAY be worth now?

17 DOWNING WAY might now be worth an estimated £389,279.

This is based on house price inflation of 39%, between November 2015 and December 2024, for 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 39% inflationary increase is applied to the most recent sale price for 17 DOWNING WAY of £280,000 on 11th November 2015. For the value to have increased from £280,000 to £389,279 over the eight years and eleven months to December 2024, the following assumptions must hold true:

• The value of 17 DOWNING WAY has moved in line with the HPI for detached houses in the West Northamptonshire local authority area.
• The November 2015 sale price of £280,000 represented a fair market value for the property.
