| Date | Price | HPI Price | Variation from HPI |

The below graph shows the average detached house price in the North Northamptonshire local authority area over time, sourced from the HPI. The two 10 WESTHILL DRIVE sales from October 1997 and April 1999 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 1997 sale was for 7% below the HPI. So the extrapolation line tracks at 7% below the HPI over time, until the April 1999 sale, where it rises to 3% above the HPI. The line then continues to track at 3% above the HPI.

10 WESTHILL DRIVE might now be worth an estimated £427,266.
This is based on house price inflation of 380.1%, between April 1999 and August 2025, for detached houses, in the North Northamptonshire local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
The 380.1% inflationary increase is applied to the most recent sale price for 10 WESTHILL DRIVE of £89,000 on 27th April 1999. For the value to have increased from £89,000 to £427,266 over the 25 years and eight months to August 2025, the following assumptions must hold true:
