12 THE SLIP 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 12 THE SLIP sales between June 1997 and June 2007 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 March 2005 sale was for 10% below the HPI. So the extrapolation line tracks at 10% below the HPI over time, until the June 2007 sale, where it rises to 5% below the HPI. The line then continues to track at 5% below the HPI.

What might 12 THE SLIP be worth now?

12 THE SLIP might now be worth an estimated £448,335.

This is based on house price inflation of 66.1%, between June 2007 and February 2025, 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 66.1% inflationary increase is applied to the most recent sale price for 12 THE SLIP of £270,000 on 19th June 2007. For the value to have increased from £270,000 to £448,335 over the eighteen years and four months to February 2025, the following assumptions must hold true:

• The value of 12 THE SLIP has moved in line with the HPI for detached houses in the West Northamptonshire local authority area.
• The June 2007 sale price of £270,000 represented a fair market value for the property.
• The size, condition, and specification of 12 THE SLIP has not materially changed since June 2007.
