15 SWIFT CLOSE 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 four 15 SWIFT CLOSE sales between December 2002 and September 2020 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 2011 sale was for 26% above the HPI. So the extrapolation line tracks at 26% above the HPI over time, until the September 2020 sale, where it falls to 20% above the HPI. The line then continues to track at 20% above the HPI.

What might 15 SWIFT CLOSE be worth now?

This is based on house price inflation of 18.2%, between September 2020 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 18.2% inflationary increase is applied to the most recent sale price for 15 SWIFT CLOSE of £480,000 on 11th September 2020. For the value to have increased from £480,000 to £567,235 over the five years and seven months to February 2025, the following assumptions must hold true:
