The below table shows the price paid for the two sales, along with the average detached price in the West Northamptonshire local authority area for the corresponding sale date.

| Date | Price | HPI Price | Variation from HPI |
|---|---|---|---|
2001 27 APR | £130,000 | £155,562 | 16% below HPI |

The below graph shows the average detached house price in the West Northamptonshire local authority area over time, sourced from the HPI. The two 46 THE SLADE sales from September 1996 and April 2001 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 September 1996 sale was for 23% below the HPI. So the extrapolation line tracks at 23% below the HPI over time, until the April 2001 sale, where it rises to 16% below the HPI. The line then continues to track at 16% below the HPI.

46 THE SLADE might now be worth an estimated £397,641.
This is based on house price inflation of 205.9%, between April 2001 and April 2026, 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 205.9% inflationary increase is applied to the most recent sale price for 46 THE SLADE of £130,000 on 27th April 2001. For the value to have increased from £130,000 to £397,641 over the 25 years to April 2026, the following assumptions must hold true:
