40 KINGSWAY Price Paid vs. HPI Average

The below graph shows the average semi-detached house price in the West Northamptonshire local authority area over time, sourced from the HPI. The two 40 KINGSWAY sales from December 2005 and July 2011 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 December 2005 sale was for 20% above the HPI. So the extrapolation line tracks at 20% above the HPI over time, until the July 2011 sale, where it rises to 29% above the HPI. The line then continues to track at 29% above the HPI.

What might 40 KINGSWAY be worth now?

40 KINGSWAY might now be worth an estimated £366,309.

This is based on house price inflation of 83.2%, between July 2011 and December 2024, for semi-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 83.2% inflationary increase is applied to the most recent sale price for 40 KINGSWAY of £200,000 on 15th July 2011. For the value to have increased from £200,000 to £366,309 over the twelve years and seven months to December 2024, the following assumptions must hold true:

• The value of 40 KINGSWAY has moved in line with the HPI for semi-detached houses in the West Northamptonshire local authority area.
• The July 2011 sale price of £200,000 represented a fair market value for the property.
