18 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 three 18 KINGSWAY sales between February 1999 and May 2014 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 February 2002 sale was for 107% above the HPI. So the extrapolation line tracks at 107% above the HPI over time, until the May 2014 sale, where it falls to 85% above the HPI. The line then continues to track at 85% above the HPI.

What might 18 KINGSWAY be worth now?

18 KINGSWAY might now be worth an estimated £523,174.

This is based on house price inflation of 64.5%, between May 2014 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 64.5% inflationary increase is applied to the most recent sale price for 18 KINGSWAY of £318,000 on 21st May 2014. For the value to have increased from £318,000 to £523,174 over the nine years and five months to December 2024, the following assumptions must hold true:

• The value of 18 KINGSWAY has moved in line with the HPI for semi-detached houses in the West Northamptonshire local authority area.
• The May 2014 sale price of £318,000 represented a fair market value for the property.
