Land registry data shows two sales for 1 THE SLIP since 1st January 1995. 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. Both of the two 1 THE SLIP sales were for below the average price. The average price is sourced from the Office for National Statistics' House Price Index (HPI).
| Date | Price | HPI Price | Variation from HPI |
|---|---|---|---|
2012 18 APR | £204,995 | £269,011 | 24% below HPI |
2011 17 NOV | £158,000 | £272,039 | 42% 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 1 THE SLIP sales from November 2011 and April 2012 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 November 2011 sale was for 42% below the HPI. So the extrapolation line tracks at 42% below the HPI over time, until the April 2012 sale, where it rises to 24% below the HPI. The line then continues to track at 24% below the HPI.

1 THE SLIP might now be worth an estimated £361,023.
This is based on house price inflation of 76.1%, between April 2012 and May 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 76.1% inflationary increase is applied to the most recent sale price for 1 THE SLIP of £204,995 on 18th April 2012. For the value to have increased from £204,995 to £361,023 over the thirteen years and eleven months to May 2026, the following assumptions must hold true:
