23 THAMES ROAD 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 23 THAMES ROAD sales between November 2001 and June 2018 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 April 2004 sale was for 5% below the HPI. So the extrapolation line tracks at 5% below the HPI over time, until the June 2018 sale, where it rises to 1% above the HPI. The line then continues to track at 1% above the HPI.
