11 MALLORY 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 11 MALLORY WAY sales between November 1999 and September 2010 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 2007 sale was for 2% below the HPI. So the extrapolation line tracks at 2% below the HPI over time, until the September 2010 sale, where it rises to 3% above the HPI. The line then continues to track at 3% above the HPI.

What might 11 MALLORY WAY be worth now?

11 MALLORY WAY might now be worth an estimated £490,814.

This is based on house price inflation of 69.2%, between September 2010 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 69.2% inflationary increase is applied to the most recent sale price for 11 MALLORY WAY of £290,000 on 17th September 2010. For the value to have increased from £290,000 to £490,814 over the fifteen years and seven months to February 2025, the following assumptions must hold true:

• The value of 11 MALLORY WAY has moved in line with the HPI for detached houses in the West Northamptonshire local authority area.
• The September 2010 sale price of £290,000 represented a fair market value for the property.
• The size, condition, and specification of 11 MALLORY WAY has not materially changed since September 2010.
